Food clean rooms are mainly used for the production and storage of beverages, milk, cheese, mushrooms and other food products. These facilities typically include designated locker rooms, air showers, airlocks, and clean production areas. Food is particularly susceptible to spoilage due to the presence of microbial particles in the air. Therefore, the sterile clean room plays a vital role in preserving food by effectively eliminating microorganisms and retaining the nutrients and flavor of food through low-temperature storage and high-temperature sterilization.
