玻璃钢（FRP）发酵罐
FRP (Fiberglass Reinforced Plastic) fermentation tanks are corrosion-resistant, lightweight, and highly durable vessels designed for microbial fermentation processes in industries such as pharmaceuticals, food and beverage, agriculture, chemical processing, and biofuel production. These tanks are engineered using advanced composite technology, combining a chemical-resistant inner lining with high-strength fiberglass reinforcement to create a sanitary, thermally stable, and long-lasting vessel capable of withstanding both biological and chemical agents.
产品性能介绍
As the demand for cost-effective, long-life fermentation vessels increases, FRP fermentation tanks have become a preferred alternative to traditional stainless steel and carbon steel tanks, especially where chemical or pH exposure is a concern.
主要特征
-
Chemical & Corrosion Resistance: Excellent resistance to organic acids, bases, solvents, and disinfectants used in cleaning (CIP/SIP systems).
-
热稳定性: Maintains mechanical integrity under fermentation temperatures up to 120°C depending on resin system.
-
Sanitary Inner Surface: Smooth, non-porous, food-safe inner liner prevents contamination, easy to clean and sterilize.
-
Customizable Configurations: Built in vertical or horizontal form, with options for conical bottoms, heating/cooling jackets, agitators, and nozzles.
-
轻巧且强度高: Easy transportation and installation, especially for large-scale tanks.
-
经济高效: Lower lifecycle cost compared to metal fermentation tanks due to corrosion resistance and minimal maintenance.
应用场景
FRP fermentation tanks are suitable for aerobic and anaerobic fermentation processes in:
-
Pharmaceutical Industry: Antibiotics, insulin, enzymes, and probiotics.
-
Food & Beverage Industry: Yogurt, kombucha, vinegar, beer, wine, soy sauce, pickles, and kimchi.
-
农业: Animal feed fermentation, silage, and biofertilizer production.
-
Biotechnology: Bioethanol, biogas, bioplastics, algae, and microbial biomass production.
-
废水处理: Anaerobic digestion for methane production.
-
