Product Description          
Vacuum pre-cooling machine, also known as vacuum cooling machine, rapid cooling machine, or fresh food cooling machine, is a sterile cooling equipment for locking and packaging high-temperature cooked food sauce and braised meat. It is an indispensable food pre-cooling mechanical equipment for solving the preservation and packaging of high-temperature cooked food in developed countries such as Europe and America.

Why we need Vacuum Pre-cooling Machine              
With fast development of economy and continuous progress of society, the living standard of people is increasingly improved, so that the sanitation of ready food is immensely strict, forming the scale production and concentrating distribution center.
The steamed, boiled and cooked food such as rice, vegetables and meat will be propagated and infected with bacteria between the temperature 30℃~60℃ if the temperature can't drop quickly. The natural cooling time is too long so that the the living place of bacteria infection and reproduction is very high, which makes food easy to deteriorate,revert and corrupt.
Traditional cooling method is natural cooling or cold store cooling. Traditional cooling time is too long and temperature difference between inside and outside is big, which may easily cause secondary pollution of food and bacteria exceeding standard.However,vacuum rapid cooling is a kind of quick evaporative cooling technique.
It puts oven-fresh deli into hermetic vacuum chamber, through vacuum depressurization,making food moisture fast evaporative cooling in low pressure to cool food.
Through this ready food using vacuum cooler, it only needs 10-25 minutes to cool from 90℃ to around 25~0℃. It effectively stride over bacteria propagating period in 30℃~60℃, avoiding the space of bacteria infection and propagation to keep color, aroma and taste. It rapidly and effectively prolongs warranty period of food.
Vacuum pre cooling machine for cooked food vacuum cooler bread cooling
Vacuum pre cooling machine for cooked food vacuum cooler applies vacuum cooling technique,which use the vacuum pump to pump the air and steam out of the vacuum tank so as to lower the inner room pressure and temperature In the low pressure,the water's boiling point is cut down,steam generate rate speed up.These conditions take the heat both the food and environment's away so as to cool the food better.
