Food-grade PP Vertical Type Storage Tanks manufactured by Xinda Chemical are widely adopted to store pharmaceutical raw materials, as their material property and structural design satisfy strict hygiene standards for pharmaceutical production. Below is a detailed breakdown.
The tank body uses food-grade polypropylene or PPH material, which has passed SGS test report and CE certification. This raw material is non-toxic, tasteless and non-extractable. It will not release harmful substances or react with pharmaceutical raw materials during contact. Unlike metal tanks, PP material will not produce metal ion contamination, preventing raw material degradation and impurity introduction. The material also resists most weak acids and aqueous pharmaceutical solutions.
Xinda Chemical adopts integral welding or winding forming technology. The tank shell has no dead corners and no hidden weld gaps. Traditional segmented tanks leave narrow crevices where residues and microbes can accumulate. The smooth inner surface of PP vertical tanks avoids material adhesion. Operators can easily clean and sanitize the tank interior, which effectively inhibits bacterial growth and cross-contamination between batches of pharmaceutical raw materials.
These vertical PP tanks can be customized with hygienic accessories as required. Optional manholes, sanitary feeding ports and discharge outlets help complete fully sealed material transfer. The ear-hanging type and flat-bottom type structures both avoid liquid stagnant zones. Flat-bottom design enables complete emptying of raw materials, eliminating residual materials that may go bad. The tank can be equipped with vent filters to block airborne pollutants entering the tank.
PP material can withstand repeated cleaning with common sanitizers such as diluted hydrogen peroxide and purified water. It will not crack, peel or shed particles after frequent cleaning cycles. Under normal temperature and pressure, the design service life exceeds 15 years. The tank maintains stable surface performance in long-term use, without scaling or corrosion that would compromise hygiene.
As a verified manufacturer, Xinda Chemical controls the whole production process of food-grade PP tanks. The finished tanks go through leakage testing and surface inspection before delivery. Wholesale service is available, and customized capacity from 0.5 ton to 100 ton supports different pharmaceutical workshop layouts. The tanks are suitable for storing liquid pharmaceutical raw materials, buffer solutions and auxiliary materials that demand high hygienic levels.
