Performance requirements for fiberglass tanks

Performance requirements for fiberglass tanks
In recent years, with the continuous progress of science and technology, fiberglass tanks have achieved rapid development in the fermentation industry, which is related to the national economy and people's livelihood. Fermentation equipment has also been updated from traditional to modern directions. Fiberglass equipment is an ideal replacement product for fermentation equipment due to its good corrosion resistance, lightweight, high-strength, and green environmental protection characteristics.
Performance requirements for fermentation equipment
1. Corrosion resistance
There are three main types of corrosive media in the fermentation industry: one is the corrosion of its products or intermediates in the production process, as well as the corrosion of the products themselves, such as citric acid, acetic acid, and salts in soy sauce; The second is the various auxiliary materials and cleaning and sterilization supplies required in the process, such as various salts, inorganic salts (hydrochloric acid, sulfuric acid, sulfite, etc.), and alkalis (sodium hydroxide, ammonia water); The third is the mixture of the above two, as well as the waste gas and wastewater that should be treated for environmental protection.
2. The material is non-toxic and can come into contact with food
Fermentation equipment needs to meet the hygiene requirements for containing food.
3. Beneficial for preventing and controlling polluting bacteria
During the fermentation process, contaminated bacteria or bacteriophages are the major enemies of the fermentation industry. Infection not only hinders the growth of production bacteria and the synthesis of products, disrupting normal production management order, but also affects the product quality of the next process. In severe cases, it can cause tank overturning, placing the fermentation liquid into the sewer, causing significant production losses. Therefore, equipment requirements are made to be free of dead corners and leaks, and its material is free of dirt, making it difficult to breed Retain defective bacterial strains, etc.
4. Has a certain strength and stiffness.
In addition to storage tanks for finished products and raw materials in the fermentation industry, some equipment also requires temperature, pressure, and agitators, such as various fermentation tanks, neutralization tanks for monosodium glutamate industry, ion exchange columns, vacuum concentration tanks for citric acid production, and so on. Therefore, there are certain strength and stiffness requirements for the materials used in manufacturing equipment.
