Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to carbon dioxide deep-freezing refrigeration equipment. Background Art

[0002] Refrigeration equipment refers to equipment used for cooling, freezing and maintaining low temperatures. They are usually used in industrial, commercial and scientific fields to meet cooling and freezing requirements under different needs. In order to keep the material fresh for a long time, it should be kept out of contact with air as much as possible and the product temperature should be quickly reduced. The spray freezing method was developed to meet these conditions. Liquid CO2 spray quick freezing is to spray liquid CO2 onto the frozen object to freeze it quickly.

[0003] Since carbon dioxide freezing isolates the air, the material will not be oxidized. When liquid CO2 is quick-frozen, CO2 directly contacts the food to cool it down, while traditional mechanical freezing transfers heat to the air medium through a heat exchanger, and then the cold air cools the food, so more heat is lost in this process.

[0004] When using the current carbon dioxide cryogenic freezing equipment, due to the different storage locations of the materials, the materials may be unevenly or incompletely contacted when sprayed with liquid carbon dioxide, which will affect the freezing effect of the materials. In addition, during the freezing process, the materials are easily frozen in the storage tank through the moisture attached to their surface, making it difficult to take out the materials after freezing. Therefore, improvements are needed. Utility Model Content
