Environment-friendly food freezing device

Abstract

The invention discloses an environment-friendly food freezing device, and belongs to the field of food freezing. The device comprises a freezer, a first shell is fixed in the freezer, a mounting frameis fixed in the first shell, an evaporator is mounted on the mounting frame, a second shell is fixed on the side wall of one side of the freezer, a compressor is installed at the inner bottom of thesecond shell, a condenser and a capillary are fixed in the second shell, an air outlet of the compressor is connected with the condenser, the air inlet of the compressor is connected with a first conduit, the other end of the first conduit is connected with the evaporator, the air outlet of the condenser is connected with the capillary, and the air outlet of the capillary is connected with the evaporator. According to the environment-friendly food freezing device, heat exchange can be effectively reduced, the freezing liquid is subjected to secondary cooling through the evaporator providing cold air, energy is saved, cost is saved, the freezing process is continuous and efficient, residual freezing liquid collection circulation can be carried out in time, operation steps are reduced, and work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of food freezing, and in particular relates to an environment-friendly food freezing equipment. Background technique [0002] At present, frozen food has become a well-known content of the public, and there are various methods of freezing. It is different from the ordinary air-cooled freezing that usually seals the air in the freezing chamber so that the food is frozen. The food is directly contacted with the liquid cooling device of the freezing liquid, which can contact the controllable freezing liquid at an ultra-low temperature to produce ultra-high-speed and uniform frozen products, so that the food to be frozen can be quickly cooled from the outside to the inside within a short period of time. Freezing can avoid the expansion of the volume of the food cells during the crystallization process of the water inside the food cells due to too slow freezing, which will lead to the damage of the cell walls, an...

AI Technical Summary

Problems solved by technology

[0003] Existing food freezing equipment usually uses low-temperature refrigerated liquid for freezing. When the refrigerated liquid rises to a certain temperature, the refrigerated liquid needs to be cooled again by adding a heat exchange device. The structure is complex and the cost is high, and the refrigerated liquid does not Recycling in time causes the refrigerant to heat up rapidly. When it is cooled again, it absorbs a lot of heat and increases energy consumption.
