The principle of vacuum cooling
Fresh fruit and vegetables contained in a closed container, whipped out the air andwater vapor as the pressure continues to drop fruits and vegetables because of constant, rapid evaporation and cooling. Vacuum cooling case cooling from within theOrganization to the outside at the same time, uniform cooling, water generally about 3%, not flaccid, loss of fresh fruits and vegetables. ease of long-term preservationand transportation.
Advantages: • long preservation time, directly without cold storage transport and short distance transport without holding;
• Cooling time very quickly, generally more than 20 minutes, but also where vent packaging can be;
• Original sensory and quality (color, aroma, flavor and nutrients) to maintain the best;
• Inhibits or kills bacteria and micro-organisms;
⒌ "thin-layer drying effect"-some small damage on the surface of fruits and vegetables can be "healed" healing or will not continue to expand;
• No pollution to the environment;
⒎ low running costs;
⒏ can extend the shelf life, the leafy vegetable vacuum pre-cooling, no refrigeratordirectly into upscale supermarkets.
