Artificial Snow 1-2

Artificial snow is small particles of ice that are used to increase the amount of snow available for winter sports such as skiing or snow boarding. It is produced by a machine that uses a high-pressure pump to spray a mist of water into the cold air. The water droplets subsequently crystallize to form fake snow. The first commercially successful machines were developed in the 1950s and improvements in technology have steadily been introduced. With the increase in the popularity of winter sports, the artificial snow market is expected to show significant growth. Background The machines that produce artificial snow are designed to mimic the way that natural snow is made. In nature, snowflakes are formed when the temperature falls below 32° F (0° C). Atmospheric water then condenses on particles in the air and crystallizes. This action produces snowflakes that have a variety of sizes and shapes. In a snow machine, water is first mixed with […]

Water to Ice: How an Ice Machine Works

There was a time when a chilled drink and refrigerated food storage were the domain of cold climates and winter days. Since Boston businessman Frederick Tudor decided in 1806 to sell blocks of ice pulled from the surfaces of New England ponds, large parts of the world have come to rely on ice as a year-round staple and dining requirement. Over a couple of centuries and some years since then, we’ve moved from fickle, hard-to-store, and sometimes dirty natural ice to cubes, flakes, and nuggets produced by ice machines. Though the process is a little less organic now, at its heart it’s no less simple than combining cold and water. Still, some steps in making ice are still a mystery even to those who have been dealing with a commercial ice maker for years. So, let’s look inside the machinery and inside the process.

Is R22 still the best option?

R-22, also known as Freon, has historically been one of the most common refrigerants used in air conditioning units and other cooling applications. However, its use has been steadily getting phased out since 2010 by the U.S. Environmental Protection Agency (EPA) due to some of the negative effects it has been shown to have on the earth’s ozone layer. Since that time, there has been a massive reduction in how much R-22 is being produced in the United States, leading to a significant increase in the cost of R-22 for homeowners. By 2020, R-22 will no longer be produced or imported in the United States at all, which means homeowners who have older AC units that rely on that coolant will likely need to upgrade to a new unit. Therefore, if you are still using R-22 as your primary refrigerant for your commercial HVAC in Eugene, OR, it’s time to start preparing for the full phase-out, which is less than two years away.

WHY WALK-IN COOLER FLOOR INSULATION IS IMPORTANT

  Commercial Walk-In Coolers for SaleProper walk-in cooler insulation helps your cooler maintain the proper temperature and keeps your inventory safe and stable. The last thing a business owner wants to deal with is needless expenses from inefficient walk-in operations. Without proper insulation, cool air is able to escape from your walk-in and warm air is able to penetrate it – causing fluctuating temperatures and humidity levels. Keeping temperatures stable and secure also helps your inventory stay fresh longer and lowers supply costs. Insulation is required for almost all walk-in coolers. The only time a walk-in does not require insulation is when it is installed on ground level cement with no other rooms underneath it.

Snowmaking is the production of snow by forcing water and pressurized air through a “snow gun,” also known as a “snow cannon.” Snowmaking is mainly used at ski resorts to supplement natural snow. This allows ski resorts to improve the reliability of their snow cover and to extend their ski seasons from late autumn to early spring. Indoor ski slopes often use snowmaking. They can generally do so year-round as they have a climate-controlled environment. The use of snowmaking machines is becoming increasingly common as changing weather patterns and the rising popularity of indoor ski resorts create a demand for snow beyond that which is provided by nature. Snowmaking machines have addressed the shortage in the supply of snow, however, there are significant environmental and cultural costs associated with the artificial production of snow.

Advantages of Having a Blast Freezer.

Food products require a lot of care. The food products should be stored with proper care. It is important that there is adequate cold storage for the food. All of the food businesses have refrigeration appliances to make sure that their food products are safe and fresh for use. The large food businesses need to have large stocks of food products at all times. Food products can only be stored if there are heavy duty refrigeration appliances available. To make sure that the food products are kept fresh, they need to be stored at the temperature of +68 C and +8 C for as little time as possible. The decreased temperature will result in decreased growth of the bacteria. The food is spoiled by the growth of the microorganisms such as the bacteria. Blast chillers: The food products can be frozen and chilled by using the freezers or the blast chillers. The blast chilling is an excellent way of making sure that the food products are not kept at […]

History of Ice Making

In 1842 John Gorrie created a system capable of refrigerating water to produce ice. Although it was a commercial failure, it inspired scientists and inventors around the world. France’s Ferdinand Carre was one of the inspired and he created an ice producing system that was simpler and smaller than that of Gorrie. During the Civil War, cities such as New Orleans could no longer get ice from New England via the coastal ice trade. Carre’s refrigeration system became the solution to New Orleans ice problems and by 1865 the city had three of Carre’s machines.[13] In 1867, in San Antonio, Texas, a French immigrant named Andrew Muhl built an ice-making machine to help service the expanding beef industry before moving it to Waco in 1871. In 1873, the patent for this machine was contracted by the Columbus Iron Works, a company acquired by the W.C. Bradley Co., which went on to produce the first commercial ice-makers in the US. By the 1870s brewe […]

INDUSTRIAL REFRIGERATION INNOVATIONS

For food and beverage processing facilities, the industrial refrigeration system is key to operations. It can also be the key investment and factor in a facility’s operational efficiency and ongoing costs for maintenance and energy use. Being environmentally responsible is becoming more important for industries across the board, and in recent years, the field of industrial refrigeration engineering has seen an array of advances in more efficient equipment and more sustainable refrigerants. However, in much of the industry, engineering practices that have been the industry standard for years are slowing the adoption and use of these new technologies. By employing older, typical engineering approaches in the design of new systems, production facilities are not only unnecessarily wasting energy and resources, which also impacts the environment, but these businesses that rely on refrigeration are wasting their cold hard cash.

Newly Identified Green Material for Refrigeration

Researchers from the UK and Spain have identified an eco-friendly solid that could replace the inefficient and polluting gases used in most refrigerators and air conditioners. When put under pressure, plastic crystals of neopentylglycol yield huge cooling effects—enough that they are competitive with conventional coolants. In addition, the material is inexpensive, widely available and functions at close to room temperature. Details are published in the journal Nature Communications. The gases currently used in the vast majority of refrigerators and air conditioners —hydrofluorocarbons and hydrocarbons (HFCs and HCs)—are toxic and flammable. When they leak into the air, they also contribute to global warming. “Refrigerators and air conditioners based on HFCs and HCs are also relatively inefficient,” said Dr. Xavier Moya, from the University of Cambridge, who led the research with Professor Josep Lluís Tamarit, from the Univer […]

Cold Rooms 101

The use of refrigerator-based equipment is a requirement of all food service operations–large or small–almost without exception. And being of such common occurrence, it’s normal to take such equipment for granted. However, like many other aspects of food service equipment, there’s always an opportunity to learn more about the use and function of refrigeration. Try to answer the following questions: * Does a refrigeration system pump cold air into a unit to lower the temperature of the food therein? Or, does it extract the heat from the food to lower its temperature? * What is the correct temperature for holding refrigerated meats, vegetables, beverages, etc.? * How long should it take to reduce cooked product temperatures from 140[degrees]F to below 40[degrees]F? * Based on meal volume, what size in cubic feet should a raw bulk storage cooler be? * Is a water-cooled refrigeration system faster than an air-cooled […]

Developments in food refrigeration

Refrigeration is a vital part of modern food production. Without a means to cool and keep food cold, the quality and safety of food would be compromised and the sophisticated cold chain we are used to would not be possible. The whole food chain is underpinned by refrigeration from primary food processing through storage, transport, retail and domestic refrigeration in consumers’ homes. Refrigerants Refrigeration systems using a working fluid or ‘refrigerant’ were invented in the early 1800s. These early systems used air, carbon dioxide, sulfur dioxide or ammonia as the refrigerating fluid. Such systems were superseded in the 1930s by CFCs (Chlorofluorocarbons) that quickly became the dominant refrigerants as they were then considered to be efficient, cheap, non-flammable and non-toxic. In the 1970s it was realized that CFCs were responsible for damaging the ozone layer and in 1989 the Montreal Protocol agreed on a phase-out of CFCs. Thi […]

History of Ice Machines

The first ever patent for an Ice Machine was granted to John Gorrie in 1851 after he had perfected his 1842 invention of a system that was able to chill water to produce ice. However, his plan to manufacture the machine for the general public was thwarted by a smear campaign led by Frederic Tudor, and the death of his partner. He died four years later in 1855, humiliated and financially ruined. He lays buried in Apalachicola, at Gorrie Square, and his original machine and plans are held at the Smithsonian Institution, Washington, D.C. Alexander Twining also received a patent for an Ice Making Machine in 1853. His experiments led to the first commercial refrigeration system in the USA (1856) and he also established the first practical method for bulk producing ice by artificial means. Professor Jürgen Hans also experimented with ice creation and in 1929 he successfully developed a machine that was capable of making ice that was edible. H […]

Making the Case for CO2 Refrigeration in Warm Climates

  For a decade or more, the potential of CO2 in supermarket refrigeration has been recognized in Northern Europe. Thanks to its unique properties, notably the high heat transfer coefficients and the low sensitivity to pressure losses, CO2 delivers high performance in supermarket applications.   In warmer climates, the advantages of CO2 in food retail applications have been disputed. In recent years, however, the interest from forward-thinking retailers has fueled the invention of new technologies that make transcritical CO2 systems in warmer climates both viable and profitable. New technologies are rapidly emerging as highly energy-efficient solutions that help retailers reduce complexity and meet current and future regulation on traditional refrigerants. In this article, we will explore the pros and cons of different solutions for CO2 refrigeration in warmer climates – from basic cascade systems to the advanced ejector techno […]

How Solar Cells Work

You’ve probably seen calculators with solar cells — devices that never need batteries and in some cases, don’t even have an off button. As long as there’s enough light, they seem to work forever. You may also have seen larger solar panels, perhaps on emergency road signs, call boxes, buoys and even in parking lots to power the lights. Although these larger panels aren’t as common as solar-powered calculators, they’re out there and not that hard to spot if you know where to look. In fact, photovoltaics — which were once used almost exclusively in space, powering satellites’ electrical systems as far back as 1958 — are being used more and more in less exotic ways. The technology continues to pop up in new devices all the time, from sunglasses to electric vehicle charging stations. The hope for a “solar revolution” has been floating around for decades — the idea that o […]

History of refrigeration

In the 1800s natural refrigeration was a vibrant part of the economy. Natural ice harvested from the pristine rivers and lakes of the northern United States, particularly those in New England, was in demand. Harvested ice was stored in large quantities in ice houses and covered with sawdust for insulation. Later, merchants loaded the ice in sailing ships as ballast. Again, the ice was covered with sawdust. Ice was delivered to as far away as India, where it was welcomed, and to England, where interest was low. The supply of harvested ice was erratic, depending on the weather where it was harvested. During the 1800s many mechanical-type refrigeration systems were being invented and used refrigerants such as sulfur dioxide, methyl chloride, ether, carbon dioxide, as well as wine, brandy, vinegar, etc. The early refrigeration systems designed between 1850 and 1920 produced ice year-round to compete with harvested ice. The harvested ice pro […]

Magnetic cooling enables efficient, ‘green’ refrigeration

Magnetic cooling is a promising new refrigeration technology boasting several advantages – ranging from lower energy consumption to eliminating the use of hazardous fluids – that combine to make it a much more environmentally friendly option than today’s standard fluid-compression form of refrigeration. One novel magnetic cooling approach, developed by a team of Canadian-Bulgarian researchers, relies on solid magnetic substances called magnetocaloric materials to act as the refrigerant in miniaturized magnetic refrigerators. As the team describes in the journal Applied Physics Letters, from AIP Publishing, these materials are the key to the development of a “green” cooling technology whose efficiency is able to scale directly with the generated magnetocaloric effect. The magnetocaloric effect is “the thermal response of a magnetic material to the change of an external magnetic field, which manifests as a change i […]

Compressors 101

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids. Types of compressors The main and important types of gas compressors are illustrated and discussed below:   Positive displacement Positive displacement compressor means a system which compresses the air by the displacement of a mechanical linkage reducing the volume (since the reduction in volume due to a piston in thermodynamics is considered as the positive displacement of the piston).   Reciprocating compressors Reciprocating compressors use pistons driven b […]

Benefits and Advantages of Thermostatic Expansion Valves Versus Other Throttling Devices

Thermostatic expansion valves (TXVs) are one of the most common types of adjustable orifice throttling device in air conditioning and refrigeration systems worldwide. They earned this place by being both efficient and affordable. But how do TXVs compare to other throttling devices? Fixed orifice devices like capillary tubes or pistons are cheaper and electronic expansion valves (EEVs) offer greater superheat control across a large load range, so why are TXVs so popular? Fixed Versus fixed orifices: orifice devices are ideal throttling devices if conditions never change. If the load on the system is constant and the ambient temperature remains steady, then a simple capillary tube or piston would be preferable to an adjustable orifice device like a TXV. However, outside of a laboratory, static conditions are simply not realistic. Seasonal temperature changes have a profound effect on system performance, as does increaseing the heat load i […]

Energy Efficient Hydrocarbon Ice Makers

For the commercial food service and related industries – which rely daily on large quantities of ice for food displays, safety, preparation, beverages and more – the ability to reliably and cost-effectively produce ice can have an impact on a business’ operation. Between 2005 and 2010, Manitowoc Ice, Inc., the Wisconsin-based manufacturer of commercial ice machines, became interested in taking their product portfolio one step further and turned to Danfoss with the idea to design an ice machine that would improve customers’ sustainability efforts by operating on natural refrigerants. The collaboration with Danfoss led to the development of two new models within Manitowoc’s Indigo Series and two Q-Series under-counter units that are cooled by R290, or propane, which Manitowoc introduced in mid-2011. The use of an environmentally friendly hydrocarbon refrigerant enables Manitowoc to offer customers a product that has zero ozone depletion p […]

Meeting Safety Requirements in Industrial Refrigeration

Modern industrial production, storage, and distribution would be impossible without the extensive use of refrigeration. Ammonia (NH3) has long been the prevalent refrigerant in industrial refrigeration due to its high degree of efficiency, low environmental impact, and affordability. Ammonia is commonly used in food processing facilities, dairies, breweries, meat processing plants and cold storage warehouses, where a large cooling demand is required. Ammonia is a cost-effective and efficient refrigerant. The only drawback is its classification as a poisonous refrigerant that in case of leakage can be harmful to personnel and the food items that the refrigeration system was designed to protect. The risk of leaks arises from many different sources, ranging from inadequate operating procedures or lack of training to failures in piping, welds or poor maintenance. Due to its classification as a poisonous gas, design, construction and operati […]

How to keep your ice clean

When making or handling ice, the below precautions should be taken. Do not store anything but ice in the ice machine storage bin so that there is no potential for contamination. Not even the scoop. Always be sure to wash your hands before handling ice or utensils that touch the ice. Only use the handle of the scoop when retrieving ice. Never handle ice with bare hands. The scoop should be kept outside of the bin in a sanitary location between uses. Employees should never use the cup or glass for customer use as a scoop. Never put ice that is unused back into the ice holding bin. Instead, discard it and start with fresh ice. All ice handling equipment such as scoops should be washed daily in the kitchen dishwasher and sanitized properly according to health department standards. If you need to store some ice outside of the bin, make use of dedicated containers that are labelled “Ice only” so that they are only used for that purpose. These […]

Ice Cubes as clear as crystal from Impure Water

An ice cube machine does not freeze ice like an ice tray. Take a look at an ice cube from an ice tray and you will see a cloudy area in the centre. Then take a look at an ice cube made from a machine. You will see that it is clear all the way through. This is what allows it to make clean ice with dirty water. Here’s how. First, only pure water freezes at 32 degrees Fahrenheit. Impure water freezes at lower temperatures. The water around the outside of the cube is exposed to the coldest first and starts to freeze. The pure water freezes around the outside and pushes the minerals towards the middle. The mineral-laden water in the middle freezes last, making the cloudy ball in the middle of an ice tray made the ice cube. But the ice cube machine makes ice without the cloudy middle. How Ice Cubes Machines Avoid Freezing Impure Water An ice cube tray holds the water in place. The pure water freezes first and then the impure water freez […]

Condensers 101

Condenser, a device for reducing a gas or vapour to a liquid. Condensers are employed in power plants to condense exhaust steam from turbines and in refrigeration plants to condense refrigerant vapours, such as ammonia and fluorinated hydrocarbons. The petroleum and chemical industries employ condensers for the condensation of hydrocarbons and other chemical vapours. In distilling operations, the device in which the vapour is transformed to a liquid state is called a condenser. All condensers operate by removing heat from the gas or vapour; once sufficient heat is eliminated, liquefaction occurs. For some applications, all that is necessary is to pass the gas through a long tube (usually arranged in a coil or other compact shape) to permit heat to escape into the surrounding air. A heat-conductive metal, such as copper, is commonly used to transport the vapour. A condenser’s efficiency is often enhanced by attaching fins (i.e., flat she […]

Refrigeration

Refrigeration, the process of removing heat from an enclosed space or from a substance for the purpose of lowering the temperature. In the industrialized nations and affluent regions in the developing world, refrigeration is chiefly used to store foodstuffs at low temperatures, thus inhibiting the destructive action of bacteria, yeast, and mold. Many perishable products can be frozen, permitting them to be kept for months and even years with little loss in nutrition or flavor or change in appearance. Air-conditioning, the use of refrigeration for comfort cooling, has also become widespread in more developed nations. Before mechanical refrigeration systems were introduced, ancient peoples, including the Greeks and Romans, cooled their food with ice transported from the mountains. Wealthy families made use of snow cellars, pits that were dug into the ground and insulated with wood and straw, to store the ice. In this manner, packed snow a […]

Solar power applications on Cold storage

Fishermen in Somalia which is located on the in the east of Africa, have no electricity. But for the past year they have been able to store their fish on cold rooms: Four cold storage rooms, powered by nothing but the scorching sun, with a capacity of storing 30 ton of fish per day. There’s a global scramble to drive down emissions of carbon dioxide: the electricity to power just refrigerators in the U.S. contributes 102 million tons annually. Solar refrigeration can also be inexpensive and it would give the electric grid much-needed relief. Electricity demand peaks on hot summer days—150 gigawatts more in summer than winter in the U.S. (A gigawatt equals one billion watts.) That’s almost 1.5 times the generating capacity of all the coal-fired power plants west of the Mississippi River. Further, solar is plentiful. The solar energy hitting 54 square feet (five square meters) of land each year is the equivalent of all the ele […]

Cold Room 101

Refrigeration is important for maintaining a proper, unbroken cold chain. Using dairy as an example, after the cows are milked, their milk is pasteurized and rapidly chilled. Once the milk has been chilled, it must be maintained at that low temperature from the farm to the grocery store, including during bottling and shipping. If the cold chain is broken, bacteria or fungus can grow, making the food unsafe for human consumption. The United States Department of Agriculture requires that business-owned refrigeration systems have an internal temperature of 40°F or below for refrigerated food and 0°F for frozen food1. Businesses operating refrigerators or freezers above these temperatures face fines and other penalties, so maintaining a reliable temperature is imperative. One of the most popular types of business-owned refrigeration systems is the cold room. Cold rooms are staples of restaurants, hotels, supermarkets, and any other place th […]

Ice Machines Preventive Maintenance

Preventive Maintenance (PM) is the key to maximum running efficiency, less downtime, and longer life out of an ice machine. The primary items for an ice machine PM check are as follows: Clean and sanitize the water system. Clean air filters on air-cooled models. Check external filter system and change cartridges as needed. Check inlet water valve screens. Conduct bearing and auger inspection on extruded ice makers. Conduct a visual inspection of components, controls, and wiring for oil spots, loose wires, loose fasteners, corrosion, etc. Clean the bin interior and unit exterior. Clean and Sanitize As ice forms on an ice machine evaporator plate, a separation occurs. Minerals separate from the water and form scale which sticks to the surfaces of the water system components. This scale will be more visible when the surfaces are dry. The color of the scale will vary due to the type of minerals in the local water supply. As an example, lime […]

Compressors 101

Pumps Versus Compressors Some people say that compressors are simply pumps that pump gas. This may be true to some extent, but significant differences exist between them. First, let’s explore the similarities. They both have positive displacement and dynamic designs capable of satisfying a broad range of flow and head requirements. Reciprocating pumps and compressors are both used for low-flow, high-head applications; centrifugal pumps and compressors are used for high flow, low-head applications and screw pumps and compressors are used for mid-flow, mid-head applications. As with pumps, multistaging can be used with any of these compressor designs whenever higher heads are required.  Both pumps and compressors use seals, bearings, lubrications systems and some type of driver. This is where the similarities end. The T-Word (Thermodynamics) The key difference between pumps and compressors is related to the thermodynamic nature of g […]

How to choose the proper ice machine

If you are in a business that relies on ice, you no doubt need an ice machine to make ice for you. However, the type of ice machine that is right for your business will vary greatly depending on what exactly you’re serving. There are several different types of ice machines and each produces a different kind of ice. If you are serving iced drinks, mixed drinks, or bagging ice to be sold or dispensed, then you will probably need a cubed ice machine. This type of machine is perfect for bars, bagging facilities, and many restaurants. Ice-o-Matic, Manitowoc, and Hoshizaki, and Scotsman all make variations of these machines. All of these produce the rhomboid ice cubes found in most bars and restaurants, with the exception of Hoshizaki’s cube, which is round. These type of ice machines offer a higher water to ice ratio, allowing for a slower melt, decreasing production. Another good choice for those in the bar or restaurant industr […]

R20 vs R404A: do the advantages outweigh the disadvantages?

According to a publication of the ‘Improving Cold Storage Equipment in Europe’ (ICE-E) project deliverables, the use of ammonia in cold stores and food processing industry applications is growing in Europe, however, the use of R404A is still quite common. In North America on the other hand, the use of ammonia is predominant, at least in large cold stores. The two refrigerants can be considered almost equivalent in terms of relationship saturation temperature/pressure, volumetric cooling capacity, thermodynamic efficiency of the reference ideal cycle. With this in mind, the “Refrigerants” information document of the ICE-E Info Pack, looks at other criteria like refrigerant cost, leakage detection, environmental compatibility or refrigerant compatibility with materials to analyze the main advantages and disadvantages of R404A and R717. Advantages of ammonia over R404A The advantages of ammonia, when compared to R404A, are cost, heat trans […]

How to determine which capacity to choose

When deciding which ice machine will be best for your needs, it is important to consider the application of the ice produced and determine the amount of ice needed. It is important to consider your ice demand during both high and low seasons, ensuring that you are never with a surplus of unusable ice or without ice in a peak season. The table below gives a good representation of ice usage estimates based on the industry your ice machine is needed for. Type of Operation Usage Food Service Restaurant 1.5 lbs. Per Person Bar/Cocktail 3.5 lbs. Per Seat Salad Bar 40 lbs. Per Cubic Foot Fast Food 5 oz. Per 7 – 10 oz. Drink 8 oz. Per 12 – 16 oz. Drink 12 oz. Per 18 – 24 oz. Drink Lodging Guest Ice 5 lbs.

Ice Making: Then & Now

There was a time when a chilled drink and refrigerated food storage were the domain of cold climates and winter days. Since Boston businessman Frederick Tudor decided in 1806 to sell blocks of ice pulled from the surfaces of New England ponds, large parts of the world have come to rely on ice as a year-round staple and dining requirement. Over the couple centuries and some years since then, we’ve moved from fickle, hard-to-store, and sometimes dirty natural ice to cubes, flakes, and nuggets produced by ice machines. Though the process is a little less organic now, at its heart it’s no less simple than combining cold and water. Still, some steps in making ice are still a mystery even to those who have been dealing with a commercial ice maker for years. So, let’s look at the machinery and inside the process. The Refrigeration System in a Commercial Ice Machine The heart of every commercial ice machine is a refrigeration system similar to […]

Refrigeration, Yesterday and Today

  REFRIGERATION     The preservation of winter ice, principally for cooling drinks in summer, was practiced from antiquity when ice was stored in insulated caves. Ice cooling was so popular in America that, within a decade of the Revolution, the United States led the world in both the production and consumption of ice. As the use of ice was extended to the preservation of fish, meat, and dairy products, ice production became a major industry in the northern states, and ice was shipped not only to the southern states but to the West Indies and South America. By 1880 the demand in New York City exceeded the capacity of 160 large commercial icehouses on the Hudson River. This industry reached its peak in 1886 when 25 million pounds were “harvested” by cutting lake and river ice with   Horse-drawn saws. The advent of mechanical refrigeration in the nineteenth century began a slow decline in the ice trade. The natural ice industr […]

Proper Ice Machine Cleaning and Maintenance

Very few end users fully understand the importance of properly cleaning and sanitizing their ice machines, storage bins, and dispensers. Many don’t even view ice as a food commodity. Yet the quality and safety of every beverage they serve as well as the longevity and power consumption of their equipment depend on the proper maintenance of this equipment. Adding to the problem is that some contractors and technicians may not realize the importance of how to properly perform this task and how to help customers maintain the quality of ice that is being consumed. Many rushes through ice machine cleaning and sanitizing using untrained, entry-level personnel to minimize the cost to their customers. In reality, they are doing their customers a disservice by not being effective at eliminating bacterial growth and scale deposits. Here are some tips that can help your company do a thorough job when cleaning this equipment and help ensure your cus […]

Compressor Checkup Tips

1. General inspection of the compressor. Check compressor shell, piping connections and mounting. To start, check the compressor for discoloration on the head and by the discharge line. This can indicate that the compressor is experiencing excessively high discharge temperatures. If you see blistered paint or a brownish tinge, make note of it. Observe the mounting grommets and make sure they are not split or missing chunks. Ensure the fastening bolts are all present and not loose. On tandem compressor arrangements, make sure the assembly is mounted as per the manufacturer’s requirements or excessive vibration can occur. Look for oil around the piping connections and below the compressor which can indicate a leak. 2. Electrical connections. Check the electrical connectors to ensure that they are tight with no free play. Loose connectors can cause poor voltage resulting in overheating of the connectors and motor. Look for discoloration of […]

Determining Proper Cooling Tower Size

To maximize cooling tower benefits, the appropriate tower size must be selected Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial and commercial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as commercial HVAC systems. As the worldwide market for these applications continues to grow, so does the need to address the issue: How large should a cooling tower be to efficiently handle a specific application. “There are a lot of different applications where you certainly don’t want an undersized cooling tower,” said John Flaherty, president of Delta Cooling Towers. Delta manufactures a line of high-density polyethylene (HDPE) engineered plastic tower models. “For example, if an undersized cooling tower is not producing cold enough water to cool the condenser loop of an office building’s HVAC chiller, t […]
