In the design of cleanrooms for the food processing industry, pass box and air shower are crucial facilities to ensure the cleanliness of the production environment.

Pass boxes are designed for the transfer of items between clean and non-clean areas, aiming to reduce the frequency of door openings. They prevent low-level contaminated air from entering high-level clean rooms, effectively minimizing the risk of contamination in the cleanroom. Pass boxer are typically made of stainless steel or cold-rolled steel, with a smooth surface for easy cleaning. They are equipped with ultraviolet germicidal lamps to ensure the sanitary safety of transferred items. Doors feature mechanical or electronic interlocking systems to ensure operational safety and consistency.

Located between changing rooms and operational areas, air showers are used for the disinfection of personnel and items before entering cleanrooms. Equipped with efficient filters and air shower devices, they effectively control the introduction of external microorganisms. Air shower rooms ensure that personnel and material flows entering cleanrooms pass through necessary disinfection steps, maintaining high cleanliness levels in the production environment.

To meet the operational needs of sterile cleanrooms for food and beverage production, the architectural layout should include:

By implementing these designs and facilities effectively, the food processing environment can achieve high cleanliness standards, complying with global food safety standards and industry regulations to ensure product quality and safety.
