Make You Know More About Direct Cooling Block Ice Machine!

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, and the ice is demolded.

The brine block ice machine uses brine as an intermediate medium for heat exchange. Its working principle is as follows:
The refrigerant cools the brine through the pipe.
The brine transfers the cold to the ice-making mold through the circulation system.
Water is poured into the mold and freezes under the cooling effect of the brine.
When the ice cubes reach the predetermined thickness, the mold is heated and the ice cubes are demolded.
Advantages and Disadvantages of Direct Cooling Block Ice Machines

Direct cooling block ice machines show significant advantages over brine block ice machines. First, their refrigeration efficiency is higher because the direct cooling block ice machine is in direct contact with the refrigerant, thereby achieving a faster ice-making speed. Secondly, the direct cooling block ice machine does not require brine as an intermediate medium, which not only reduces energy consumption, but also reduces environmental pollution, showing higher energy-saving and environmental protection performance. In addition, the direct cooling block ice machine has a simple design, and is easier to operate and maintain. At the same time, it avoids the use of brine, making the produced ice cubes cleaner and more hygienic. However, direct cooling block ice machines also have some shortcomings, such as high initial investment costs, and the refrigeration effect may be affected to a certain extent in extreme environments. In contrast, although the brine block ice machine has a lower cost and strong adaptability, its shortcomings such as low refrigeration efficiency, high energy consumption, and complex maintenance limit its scope of application.

Block ice has the following advantages over other forms of ice (such as flake ice, tube ice, etc.):
Slow melting speed: Block ice is large in size, melts slowly, and can maintain low temperatures for a long time.
Easy to store: Block ice is easy to store and transport, suitable for large-scale applications.
Good cooling effect: Block ice has a high density and can provide a longer-lasting cooling effect.

Direct cooling block ice machines are widely used in the following fields:
Food preservation: used for the preservation and transportation of aquatic products, meat, fruits and vegetables, etc. to ensure the freshness of food.
Industrial cooling: used for cooling in industrial fields such as chemical and pharmaceutical industries to ensure the stability of the production process.
Emergency rescue: Provide cooling and preservation support in emergency situations such as natural disasters.
Commercial application: used in commercial places such as bars and restaurants to provide customers with high-quality ice cubes.

Direct cooling block ice machines occupy an important position in the ice making field with their high efficiency, energy saving and environmental protection. Despite the high initial investment cost, its superior performance and wide application prospects make it an important direction for the development of ice making technology in the future. For users who pursue high-quality ice making effects, direct cooling block ice machines are undoubtedly the best choice.
