Generally speaking, food processing is raw materials - semi-finished products - finished products, processing plant shall be in accordance with the order of the product processing process layout, that is, from the non-clean to the clean link transition, do not allow the processing process in the cross and backflow. Between the clean area and non-clean area to take appropriate isolation measures in order to control the flow of people and logistics between each other, so as to avoid cross-contamination, processed goods transfer through the transfer window.
2, the processing of raw materials and production of finished products using the same clean area
Raw material acceptance, acceptance, raw material pre-treatment and raw material storage, all production and processing until the finished product into the warehouse, the requirements of a production line, to eliminate cross-pollution of production and processing.
3, aseptic clean room space to be compatible with the production
The size of the clean room depending on the need, in general, the production of clean room processing personnel per capita has an area of (in addition to equipment) of not less than 1.5 square meters. Overcrowded clean room, not only hinder the production operation, but also the mutual collision between personnel, personnel overalls and production equipment contact, it is easy to cause product contamination. In addition, the walls of the workshop should be smooth without dead ends for cleaning and disinfection. Clean room should be closed and keep the workshop static pressure difference for positive pressure, set up air disinfection with ultraviolet lamps, ozone sterilization, air filtration purifiers and air purification devices.
4, the production area, living area and factory layout
Living area (including dormitories, canteens, bathrooms, etc.) should be located in the production area upwind. Pre-plant area (including communication room, office building, parking lot, garage, etc.) should be separated from the production area. Logistics corridor and dust-producing buildings, such as boiler room, to be built in the plant downwind side of the year-round dominant wind direction. Mutually influential production processes, should not be located in the same building, the respective production areas should be effective partition measures. Production of fermented products should have a dedicated fermentation workshop.
