refrigeration equipment

Abstract

The invention provides refrigerating equipment. The refrigerating equipment comprises a freezing chamber used for containing frozen objects, a freezing circulating system comprising a compressor, a condenser, an expansion mechanism and an evaporator which are connected together, an air supply path used for conveying cool air generated by the evaporator, a pallet used for bearing the frozen objects in the freezing chamber and provided with a plurality of through holes, and a blower used for blowing the cool air conveyed by the air supply path towards the pallet on the lower portion in the freezing chamber, wherein the evaporator is used for generating refrigerating cool air through cooling; and an air supply cavity is formed in the bottom of the pallet and used for receiving the cool air conveyed by the air supply path and discharging the cool air through through holes in the bottom of the pallet upwards. Food is frozen effectively through supercooling so that the supercooling effect can be improved.

Description

technical field [0001] The present invention relates to a refrigerating device for cooling and preserving food etc. in a storage room, and more particularly to a refrigerating device having the function of supercooling and freezing the food etc. in the freezing room. Background technique [0002] So far, the freezing method of freezing food through a supercooled state during freezing in the freezer has been used. When this method is used, because the ice crystals are small, it is not easy to damage the cells of the food, so the effect of reducing blood loss can be obtained. Chinese Patent No. 2016100332561 discloses a refrigeration device with the above-mentioned supercooling function. By using a loading plate with through holes to place items that need to be overcooled, the cold air output from the air duct at the top of the loading plate passes through the through holes from the loading Items are refrigerated on both the upper and lower portions of the shelf. However, in ...

Problems solved by technology

However, in the actual use process, it is found that the amount of cold air entering the bottom from the through hole of the mounting plate is relatively small, and the effect of supercooling is still not well achieved.
