Determination of the form of Unit Cooler Defrosting There are three types of defrosting methods currently used in refrigeration systems, water defrosting, hot gas defrosting, and electric defrosting. Ⅰ Situation analysis： The original system uses ammonia refrigerant, and the defrosting method is water defrosting, which causes serious water accumulation in the cold storage room, and the temperature of the room is -18~-22℃, and the accumulation of water is frozen, which affects the storage of the products. a) Analyze the causes: ①Because of incomplete defrosting, the chiller enters the cooling mode without completing the defrosting process, resulting in ice blockage of ...

Food Storage and Cooling Technology Refrigeration cycle according to the principle of refrigeration compressor, condenser, throttle and evaporator, and in order to make the refrigeration more efficient, safer operation of auxiliary equipment (oil separator, reservoir, gas-liquid separator, circulating reservoirs, oil collector, air bleeder, valves, instrumentation, etc.) connected into a closed and refrigeration cycle. Refrigeration process design is directly related to the quality of food cold processing and dry loss, but also has an impact on the operating efficiency of cold storage enterprises. The next few common types of cooling rooms are introduced to you. Meat Cooling Room Just after the ...

What are the Food Freezing Devices? In recent years, the processing and consumption of frozen food has been growing rapidly, and there are more and more varieties of colours, and the quality requirements for frozen food are getting higher and higher. In order to adapt to the technological characteristics of different foods, shorten the freezing time, and improve the quality and production efficiency of frozen food, the freezing process of food has evolved from a single freezing room freezing to the use of a variety of new types of continuous freezing devices for freezing and processing. Compared with general freezing ...
