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

Embodiment Construction

[0014] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0015] figure 1 It is a structural schematic diagram of a vacuum precooler of the present invention.

[0016] Such as figure 1 As shown, a vacuum precooler 100 provided by the present invention includes a vacuum system, an ozone generator 2, a refrigeration system and a water supply system.

[0017] The vacuum system has a vacuum chamber 18 , a Roots pump 17 and a water ring pump 9 , the vacuum chamber 18 is used to accommodate materials, and the Roots pump 17 and the water ring pump 9 are used to evacuate the vacuum chamber 18 . The vacuum chamber 18, the Roots pump 17 and the water ring pump 9 are connected in sequence through a vacuum pipeline. In this embodiment, the vacuum system also has a frequency converter 15 connected to the water ring pump 9 for controlling the power of the water ring pump 9 .
