Foods produced in a clean room, because of their high degree of cleanliness can ensure that food is not attached to bacteria, but can not eliminate the bacteria originally brought by the food, so it also needs heating, spraying, irradiation and other methods of sterilization.
Many food clean rooms are mainly used for cooling, cutting (sheets), and packaging after sterilization.
In the [Beverage Enterprise Good Manufacturing Practices" (GB12695-2003), it is required that the filling area is partially class 100 (Grade 5), the clean area is 10000 (Grade 7), and the quasi-clean area is 100,000 (Grade 8).
