The design flexibility of FRP storage tanks is excellent, and the performance of the tank wall is excellent. Fiber-reinforced FRP can change the resin system or reinforcing material to the high-speed FRP storage tanks and the physical and chemical properties of non-standard devices to meet the needs of different media and working conditions. Through the structure layer thickness, winding angle and wall thickness structure and design to adjust the bearing capacity of the tank body, made of FRP storage tanks and non-standard devices with different pressure levels or some special properties, which is not an isotropic metal material Compared to.
FRP storage tanks are popular because they have the following characteristics:
There are mainly three types of corrosive media in the fermentation industry: one is the corrosion of its products or intermediates in the production process and the product itself, such as: citric acid, acetic acid, salts in soy sauce, etc .; the second is necessary in the process Various auxiliary materials and cleaning sterilization supplies, such as: various salts, inorganic salts (hydrochloric acid, sulfuric acid, sulfurous acid, etc.), alkalis (sodium hydroxide, ammonia water); the third is a mixture of the above two, and should be environmentally friendly Waste gas, wastewater, etc.
2. The material is non-toxic and can contact food
Fermentation equipment must meet the hygienic requirements of foods.
3. Conducive to the prevention and control of contaminated bacteria
During the fermentation process, contaminating bacteria or phages are the enemy of the fermentation industry. Bacteria infection not only hinders the growth of production strains and the synthesis of products, disrupts the normal production management order, but also affects the product quality of the next process. In the tank, the fermentation broth is put into the sewer, which causes great losses in production. Therefore, the equipment is required to have no dead ends and no leakage, and its material is free of dirt, which is not easy to breed and retain bad bacteria.
4, have a certain strength and stiffness.
In addition to storage tanks for finished products and raw and auxiliary materials in the fermentation industry, some equipment also requires temperature, pressure, and agitator requirements, such as various fermentation tanks, neutralization tanks for the MSG industry, ion exchange columns, and vacuum concentration for citric acid production. Cans and more. Therefore, there are certain strength and rigidity requirements for the materials of manufacturing equipment.
