Working principle of food packaging machine

Food vacuum cooling machine is a crucial equipment for packaging food preservation and safety. Compared with general cooling methods such as natural cooling, blast cooling, and cold room cooling, it can not only achieve sterile cooling, but also has a faster cooling speed (only 5-15 minutes, while general cooling methods require at least a few hours to several tens of hours). It can also achieve uniform cooling of the food center and surface simultaneously, avoiding the breeding temperature zone of bacteria between 55 ℃ and 30 ℃, ensuring the hygiene quality of food cooling. It is a key technical equipment to ensure the safety of packaged food and prevent food poisoning.
