"Food is the most important thing for the people, and the disease comes from the mouth", which shows the importance of food hygiene and safety. In order to ensure the quality and safety of food safety, it is necessary to analyze, evaluate and control the possible hazards in all aspects from raw material procurement to product processing, production, packaging and so on. Especially in the process of production and processing, food will frequently come into contact with personnel, equipment and exposed to the air. It is easy to be contaminated by microorganisms or micro dust particles, which will lead to bad results such as mildew and decay of food. In this way, we must rely on clean production environment to achieve the control of food production environment. Through the construction of aseptic clean workshop, we can continuously improve and improve the safety of food.
Clean workshop?
Clean workshop is also called dust-free workshop, clean room and clean room. It refers to the elimination of pollutants such as particles, harmful air, bacteria and other pollutants in the air within a certain space range, and control the indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise, vibration, illumination and static electricity within a certain range of demand. That is, no matter how the external air conditions change, the indoor can maintain the original set requirements of cleanliness, temperature, humidity and pressure characteristics. For different industries, different production links may have different specific requirements, but according to the air level, it is generally divided into four levels: 300000, 100000, 10000 and 100.
100000 class clean workshop?
For the food and beverage clean workshop, it is necessary to reach the air purification standard of class 100000. Simply speaking, the number of particles with diameter ≥ 0.5 μ m per cubic meter in the workshop is no more than 3.52 million. The less the number of particles in the air, the less dust and microorganisms. The cleaner the air is. The 100000 class clean workshop also requires 15-19 air changes per hour, and the air purification time should not exceed 40 minutes after complete air exchange. In order to strictly control the air quality of clean room, it is necessary to select qualified and reliable air filter products. It mainly adopts centralized air purification treatment, which is composed of standard combined air conditioning cabinet + air filtration system + clean room ventilation and insulation pipe + HEPA efficient air supply outlet + clean room return air duct system. Continuous circulation and supply of fresh air into the clean workshop will achieve the required cleanliness of the production environment.
