| Brief Introduction There must be cooling process in the production of cooked food such as pork, poultry, rice and bean made products, vegetable, bread, cake etc. The quality and quality preservation duration is closely related with the speed and effect of the cooling. The traditional cooling styles are always natural cooling or cooling in the refrigeration house with long cooling time and a big inside-outside temperature difference, liable to "second pollution". Vacuum cooler of cooked food adopts advanced vacuum cooling technology to aseptically cool the cooked food in the fully-isolated stainless steel chamber. It reduces the environment pressure of the products being cooled so that the boiling point of the water in the products is lowered to have the water vaporized to absorb the products themselves' heat, then to lower the products' temperature. It can avoid the second pollution and get across the temperature range of 25~50 centigrade which is very suitable for the breed of bacteria with rapid cooling speed, as well as cool the center and surface of food to the expected temperature at the same time to furthest make sure the cooling rapidly and evenly so that the quality and safety of the cooked food is improved greatly and the preservation period is extended. There are 3 series of vacuum cooler of cooked food including normal temperature series (3~5 centigrade higher than that of cooling water), low temperature series(3~8 centigrad), medium temperature series(15-20centigrade). The medium temperature vacuum cooling machine which is specially designed by SGET with brand new design concept has a lot of advantages over normal temperature and low temperature cooling machine. Comparing with normal temperature series, the advantages are: 1. Better cooling quality, can reach lower and more stable final cooling temperature in all seasons, which is different from normal temperature series that is influenced by the temperature of cooling water. 2. Solve the problem of "liquid splashing" 3. Much less water consumption Comparing with low temperature series, the advantages are: 1. The structure is much more simplified 2. Less motion parts in the machine to lower the cost and improve the reliability 3. Lower noise 4. Less power consumption to reduce the operation cost 5. Smaller dimension to reduce over 40% occupation area. |
