How food packaging machines work

Food vacuum cooler is the key equipment for packaging food preservation and safety. Compared with the general cooling method (natural cooling, blast cooling, cold room cooling), it can not only achieve aseptic cooling, but also has a faster cooling rate (only 5 to 15 minutes, the general cooling method requires at least several hours to tens of hours). It can also achieve uniform cooling of the food center and surface at the same time, thus avoiding the breeding temperature zone of bacteria between 55 °C and 30 °C, ensuring the hygienic quality of food cooling, and the key technology for ensuring the safety of packaged food and preventing food poisoning. equipment.
