Freezing is a widely used method of food preservation however many food products are sensitive to the freezing process, which affects quality, nutritional value, and appearance thus, the freezing method and system selected can have substantial impact on quality and economy.as compared to other freezing methods, the most significant advantage of a blast freezer is their versatility and fitness for various uses. Blast freezers tend to be a good choice for products that are irregular in size and shape.to achieve the desired result in a blast freezer, the size and capacity of evaporators and refrigerating machines should be in harmony with each other which makes the task of creating and designing an ideal, versatile and flexible shock freezer for any application very difficult for example if the room is not properly sized and get overloaded, the air temperature rises and freezing time extends; at the same time, the outlet pressure of the refrigeration compressor rises. In this case if the system is not equipped with proper safety measures this can lead to serious damage in the compressor. Loading the room with less than its capacity does not lead to as serious problems as overloading, but increases operation costs.
