Superiority:

Huangshi Jiake Environmental Protection Technology Co., Ltd. has a building area of more than 150,000 square meters. It is a professional manufacturer of high-purity industrial-grade anhydrous sodium sulfite and sodium metabisulfite. We have annual productive capacities of 200,000 tons of anhydrous sodium sulfite with purity 96~98%.

We have experienced technicians, leading facilities, a modern management system and an excellent after-sale service system. We use the Mechanical Vapor Recompression technology for production and Automachine for package. Our products is clean and pure, the quality is over food grade standard. Output of sodium metabisulfite covers over 18 provinces in china market，our production capacity is leading globally.

Details:

We use experienced technology for production. First,extract the chean gas of sulfur dioxide from the production part of sulfuric acid, Mixture with food grade sodium carbonate,it comes out high quality sodium hydrogen sulfite. Second,after chemical treatment of sodium hydrogen sulfite ,mixture with ionic membrane sodium hydroxide, generated sodium sulfite with water. After concentration, desiccation and crystallization,it comes out sodium sulfite anhydrous,then we packed up the products into the warehouse.
