In the processing and storage of meat products, the pass box plays a vital role. It can effectively prevent cross-contamination and ensure product quality. Here are some key requirements that the pass box should meet.

Firstly, the pass box should have excellent sealing performance. This can prevent external pollutants from entering and also stop the internal odors and microorganisms from spreading out. Secondly, the choice of materials is crucial. Corrosion-resistant and easy-to-clean materials, such as stainless steel, should be used for convenient daily maintenance and hygiene treatment. Additionally, the pass box needs to have suitable internal lighting, enabling operators to clearly see the items inside and avoid misoperations.

Furthermore, ultraviolet germicidal lamps are also necessary. By using ultraviolet germicidal lamps, the number of microorganisms inside can be reduced, providing a safer environment for meat products. Finally, the doors of the transfer window should have interlocking functions to prevent both sides from opening at the same time, thus avoiding air circulation and cross-contamination.

In conclusion, in the processing and storage of meat products, only when the pass box meets these key requirements can it better play its role and ensure the safety and quality of meat products.
