Embodiment Construction

[0015] see Figure 1-Figure 3 , an immersion quick-freezing machine includes a low-temperature refrigeration unit A, a brine pool 8 and a transport assembly, and there is a pipeline connection between the brine pool 8 and the refrigerating low-temperature refrigeration unit A to realize heat exchange. The brine pool 8 is arranged in the storage body 10 to prevent the cold loss in the brine pool.

[0016] The low-temperature refrigeration unit A includes a bottom frame 2 and a bipolar compressor 1, a condenser 3, an evaporator 5, an oil separator 7, a gas-liquid separator 4, an expansion valve 12, an economizer 13 and an electric control box arranged on it 6. Bipolar compressor 1, condenser 3, evaporator 5, oil separator 7, gas-liquid separator 4, expansion valve 12 and economizer 13 are connected by pipelines to form a refrigeration cycle, and the pipelines are equipped with control components and The electric control box 6 is connected, and the refrigerant in the refrigerati...

Abstract

The invention belongs to the technical field of freezing and provides an immersing type instant freezer. The immersing type instant freezer comprises a low-temperature refrigerating set, a refrigerating medium tank and a conveying assembly, wherein the refrigerating set and a refrigerating medium circulating pipeline of the refrigerating medium tank are subjected to heat exchange; the conveying assembly comprises a conveying belt and a transmission accessory thereof; and the conveying belt extends to the outer part through the refrigerating medium tank. The immersing type instant freezer disclosed by the invention has the advantages of fast freezing speed, short freezing time, less dehydration loss of frozen products, very high quality of the frozen products, and capability of realizing continuous freezing production; and compared with conventional flat plate type instant freezing, the immersing type instant freezer has a small occupied space and less energy consumption.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to an immersion refrigerator. Background technique [0002] Quick freezing refers to the method in which food quickly passes through its maximum ice crystal formation area and freezes rapidly when the average temperature reaches -18°C. Food undergoes various changes during the freezing process, such as physical changes, chemical changes, cell tissue changes, and biological and microbial changes. Quick-frozen food is characterized by maintaining the original nutritional value, color, flavor and flavor of the food to the greatest extent. That is to say, it is necessary to ensure the maximum reversibility of the above-mentioned changes in the food during the freezing process. [0003] The existing quick-freezing device adopts the traditional flat-plate air-cooled quick-freezing machine, the cooling medium is air, the heat transfer coefficient is low, the freezing time is long, and the dehydr...
