Price list of electric high-temperature butterfly valve Selection of valve data in food pipeline
In the past, when people's life and death level is getting higher and higher, food and clothing problems will not appear at all, and the demand for food is getting higher and higher, especially in the past, people often report a series of food safety problems such as gutter oil here, Sudan red there, and so on. So people also pay great attention to food safety, and in food processing plants, There are some valves used in food pipes. The material requirements for such valves are stricter than those for transporting food.
Food grade valves use imported silicone collagen materials, apply scientific consumption process, and adopt the intermittent method to stop the consumption of raw rubber. This product is a high-quality silicone rubber tube that stops consumption for the characteristics of high tear resistance and high transparency of gas phase rubber, ultra-high and lower hardness of rubber mix, functional rubber mix, and so on. This product has more universal compliance. Compared with the silicone tube and silica gel profiled material of the traditional double two four vulcanization process, it has the advantages of high transparency, no smell, no yellowing, no frosting, etc., especially the problem of black tube frosting, and the fading of blue products. It is non-toxic and tasteless, with stable chemical performance. Under normal conditions, except for caustic soda and hydrofluoric acid, it does not react with any acid, alkali or salt. As it is a colloidal structure, it has many micropores and a large specific surface area. The pore diameter of edible silica gel is about 8-10nm. In the test, the specific surface area of silicon is 300-500m2/g, and the surface is hydrophilic. It has a strong ability to absorb water. Under high humidity conditions, its water absorption capacity can reach 80% - 100% of its own weight. Therefore, food grade silica gel can be used as external drying agent for food and medicine. As the edible silica gel is refined and sterilized, it can be directly mixed with food and drugs according to demand to ensure that the food is dry and eaten with food, without any toxic reaction to human body.
