The installation and construction of the clean room of Malata Food Factory is to ensure the treatment of food and extend its warranty period. The name of food is an ancient and permanent word, and people can only survive by relying on food. Today, people's pursuit of food has higher conditions.
The food factory clean room is the product of the society's high quality requirements for food. It consists of a central air conditioning and air purification system, which is the heart of the purification system. It mainly controls the number of air dust particles in the purification workshop and adjusts the temperature and humidity of the workshop. The design requirements of the clean workshop of the food factory are also very high. The workshop adopts the air shower channel to blow off the dust attached to the surface of the person entering the clean workshop and the object, and at the same time acts as an air brake to prevent the unpurified air from entering the clean area. It is an effective device for personal and material purification and for preventing outdoor air from entering the clean area. The air shower has a chassis-free and sill configuration, which provides convenience for trucks to enter and exit. The cargo shower room is equipped with infrared device spray to implement automatic control. Through photoelectric induction, the two doors are interlocked and automatically closed, which provides convenience for people (goods) to enter and exit.
Method for grading detection of indoor air pollution degree in clean workshop of food factory
1. The medium was prepared and sterilized according to the preparation requirements of each medium, and the culture dish (9 cm) was sterilized by dry heat (160 ° C, 2 h). Pour 15~20ml of medium into each dish and use it after cooling and solidification.
2. Space microbiological testing should be carried out under dynamic conditions (detection under static conditions for assessing spatial disinfection effects).
3, layout: the area is less than 30 square, take the diagonal three points, that is, the two ends, the middle three points; the area is greater than 30 squares take two diagonal five points; the sampling point is 1 meter away from the wall, 1 meter away from the ground, avoid Open the door and window air circulation.
4. Adopt natural sedimentation method: open the plate cover and expose the plate to air for 5 minutes.
5. Culture: The total number of bacteria was cultured at 36 °C ± 1 °C for 48 ± 2 hours.
6. Counting: Count the number of colonies on each plate, find the average number of colonies at all sampling points, record the average number of colonies, and report the results in "single/plate".
The reason why it can be called a food factory clean workshop is that it should be clean and hygienic and clean. These people have a standard in entering and exiting people. They can not go in casually, and they are organized in an orderly manner. They care about every rule and regulation. , can be a qualified clean workshop.
