"Disease comes from the mouth", and food hygiene is directly related to people's health. Whether it is the processing workshop and packaging workshop of the food factory, there are high hygiene standards and requirements. Among them, microbial contamination is the most important factor affecting food quality, and it is also the focus of the purification project in the packaging workshop and processing workshop of the food factory.
Food safety and hygiene should be controlled in three aspects: first, control the standardized operation of production personnel; The second is to control external environmental pollution (to establish a relatively purified operating space. The third is to purchase raw materials from the source to eliminate problematic products.
The construction of a good hygienic production environment for food purification workshop is mainly based on five aspects: key control area, background area, food contact surface, personal purification room, and material purification room.
Critical control area, an area in the purification room in the food processing process, if the area is not properly controlled, it is very likely to cause harm and can easily lead to contamination of the finished product.
The background area, the area around the critical control area in the same purification room.
Food contact surfaces, those surfaces that come into contact with food, and those surfaces that will drip on food or splash on food during normal processing.
A personal purification room, a room where the staff decontaminates according to certain procedures before entering the purification area.
Material purification room, a room where materials are purified according to a certain procedure before entering the purification area.
The purification plant of the food factory should be graded according to the requirements of sterilization, dust removal and hygiene according to food production. The food dust-free workshop should clarify the key control points, key areas and background areas of production, and should be graded separately, and the area of high-level areas should be reduced as much as possible.
Requirements for clean workshops.
The process that has aseptic requirements but cannot be sterilized but cannot be sterilized and the process that can achieve terminal sterilization but is aseptic after sterilization should be carried out in the purification workshop.
The purification workshop with the requirements of a good hygienic production environment shall include the storage and processing places for perishable food, ready-to-eat semi-finished products or finished products before the final cooling or packaging, the pre-treatment of raw materials, product sealing and molding sites that cannot be terminally sterilized, the exposure environment after the final sterilization of products, the preparation area and inner packaging room of the inner packaging materials, as well as the processing and processing places and inspection rooms for food production and improving food characteristics or preservation.
The production process of the workshop and the corresponding level of the purification room require a reasonable layout. The line layout should not cause round-trip crossovers and discontinuities.
The different workshops that are connected to each other in the production area should meet the needs of varieties and processes, and if necessary, there should be buffer rooms and other measures to prevent cross-contamination, and the buffer room area should not be less than 3 square meters.
The pre-treatment of raw materials and the production of finished products do not use the same purification area.
The area and space suitable for the production scale in the production workshop should be used as a temporary storage area for materials, intermediate products, products to be inspected and finished products, and crossing, confusion and pollution should be strictly prevented.
The laboratory should be set up independently, and there should be proper treatment measures for its exhaust and drainage. If there is an air purification requirement for the inspection process of the product, a purification workbench should be set up.
