Proper operation and maintenance are crucial when using cold storage, as they ensure stable operation, reduce failures, and extend the lifespan of the facility. Here are the main precautions to consider when using cold storage:   1. Keep the Cold Storage Clean Maintaining cleanliness inside the cold storage is fundamental to its normal operation. Regularly clean the interior to prevent the accumulation of dust, dirt, and mold, which is especially important for cold storage facilities that handle food. Floors, walls, and shelves inside the cold storage should be cleaned and disinfected regularly to ensure a hygienic environment, preventing food contamination and the development of unpleasant odors.   2. Control Temperature and Humidity The temperature and humidity levels within the cold storage are critical for preserving stored items. It’s important to set appropriate temperature and humidity parameters based on the char […]

When selecting an ice machine, the choice of cooling method is a crucial consideration. The cooling method not only affects the efficiency and performance of the ice machine but also directly impacts operating costs, equipment maintenance, and environmental adaptability. The three main cooling methods available on the market today are air-cooled, water-cooled, and evaporative-cooled. Each method has its own advantages and suitable scenarios. This article will explore the characteristics of these three cooling methods and their applicable situations to help you make a more informed decision.   I. Air-Cooled Ice Machines Air-cooled ice machines use fans to blow air over the condenser, dissipating the heat carried by the refrigerant into the surrounding air. This method relies on the ambient air to complete the cooling process, with the temperature of the condenser fluctuating according to the environmental temperature. Advantages Eas […]

The particle ice machine is a device specially used to produce particle ice cubes. Its basic structure mainly includes the following parts: Compressor: It is the core component of the particle ice machine and is responsible for compressing the refrigerant to produce a freezing effect. Evaporator: It converts water into ice by absorbing heat and is the main component of the ice machine to freeze water. Condenser: Cools the compressed refrigerant, usually by air cooling or water cooling. Ice storage bucket: It is used to store the produced particle ice and usually has a heat preservation function to maintain the quality of ice cubes. Control system: It includes electrical control and programming systems to monitor and adjust the entire ice making process. The working principle of the particle ice machine is based on the refrigeration cycle and the water freezing process. First, the compressor compresses the low-pressure refrigerant into a […]

Block ice machine is a common ice-making equipment, widely used in food preservation, cold chain transportation, industrial cooling and other fields. Block ice machine is mainly divided into two types: direct cooling block ice machine and brine block ice machine. This article will focus on the direct cooling block ice machine, and explore its working principle, advantages and disadvantages, and application in different fields. Direct cooling block ice machine makes ice by direct contact with refrigerant. This design eliminates the intermediate medium, making the heat exchange process more efficient. The working principle of direct cooling block ice machine is as follows: The refrigerant directly contacts the ice-making mold through the cooling pipe. Water is poured into the mold and freezes quickly under the action of the refrigerant. When the ice reaches the predetermined thickness, the refrigerant stops circulating, the mold is heated […]

The development of cold storage can be traced back to the time when humans began to use natural ice and snow to preserve food. With the advancement of science and technology, cold storage technology has gradually evolved and has gone through several important stages. In ancient times, humans relied on natural ice and snow to preserve food. For example, ancient Chinese ice cellars used ice and snow collected in winter to store food, and ancient civilizations such as Egypt, Greece, and Rome also had similar technologies. Although this method is simple, it is limited by climatic conditions and storage time. In the early 19th century, mechanical refrigeration technology began to appear, marking a revolutionary advancement in cold storage technology. In 1805, American Oliver Evans designed the first vapor compression refrigerator. Subsequently, John Gorrie of Britain and Carl von Linde of Germany successfully manufactured practical refrigera […]

The refrigeration system is a general term for the equipment and pipelines through which the refrigerant flows, including compressors, condensers, throttling devices, evaporators, pipelines and auxiliary equipment. It is the main component system of air conditioning equipment, cooling and refrigeration equipment. The blockage failure of the refrigeration system has many forms such as ice blockage, dirty blockage and oil blockage. The unified fault characteristics of blockage are: the condenser is not hot when touched, the evaporator is not cold, the compressor operating current is smaller than normal, the pressure gauge is connected to the bypass charging valve, indicating negative pressure, the outdoor unit is running light, and there is no sound of liquid in the evaporator. Causes and fault phenomena of ice blockage The occurrence of ice blockage failure is mainly due to excessive moisture in the refrigeration system. With the continu […]
