Vacuum pre-cooling machine

Abstract

The invention provides a vacuum pre-cooling machine which is used for carrying out vacuum pre-cooling on materials. The vacuum pre-cooling machine comprises a vacuum system, an ozone generator, a refrigeration system and a water supplementing system. The vacuum system is provided with a vacuum chamber, a Roots pump and a water ring pump, which are connected in sequence through a vacuum pipeline; the vacuum chamber is used for storing materials; the Roots pump and the water ring pump are used for vacuumizing the vacuum chamber; the ozone generator is communicated with the vacuum chamber through a pipeline and is used for carrying out pressure returning, sterilization and disinfection on the vacuum chamber; the refrigeration system is used for cooling gas pumped by the Roots pump and the water ring pump and is provided with an open type water catching device, a compressor and a condenser, which are connected in sequence through a pipeline; the open type water catching device is further connected with the water ring pump through a pipeline; the water supplementing system is provided with a water tank of small molecule water, which is communicated with the vacuum chamber, and is used for supplementing water for materials; the water tank of the small molecule water is used for storing the small molecule water.

Problems solved by technology

[0004] At present, vacuum pre-coolers on the market mostly use closed water traps. After working for a period of time, a large amount of grease will condense on the surface of the water trap coils. Due to the closed type, it is not conducive to cleaning the coils, resulting in reduced cooling effects and food cooling time. Prolonged, increased production costs

Vacuum cooling technology uses part of the food itself to evaporate and absorb heat to cool down. After vacuum cooling, the food moisture is reduced. Research data shows that the weight loss rate of cooked meat after cooling is 7% to 10%. Too much weight loss will affect the quality and flav
