Qingdao Kehai Biochemistry Co., Ltd.
Qingdao Kehai Biochemistry Co., Ltd, a subsidiary of Qingdao Langyatai Group Co., Ltd, is a high-new technology company and key biotechnology enterprises in Qingdao. Its leading products include itaconic acid series and sodium gluconate series. The itaconic acid has achieved an annual output of 10,000 tons; sodium gluconate has reached 50,000 tons on production capacity.
Qingdao Kehai Biochemistry Co,. Ltd has set up bio-fermentation engineering technology research centers with strong technique power. Laying technology as the basis and continual technology innovation, the company has firstly in China established complete production line based on GMP standard and utilized automatic control. The level of its refined process technology has fully reached that of Japan, USA and other advanced countries, and its quality has completely attained and even exceeded international standard. In recent years, in order to research and develop derivatives of itaconic acid, Qingdao Kehai Biochemistry Co,. Ltd gradually increases science investment and strengthens cooperation with research colleges and institutes. It has developed successfully tartaric acid, itaconic anhydride, dimethyl itaconate, Scale - Corrosion Inhibitor, Dibutyl Itaconic, Itaconic acid octyl and so on. Dimethyl itaconate has been classified as a state-level new product, scale- corrosion inhibitors Program has been included in the national key promotion projects as to fill the domestic blank. Meanwhile, itaconic acid projects with 10,000 tons are recognized as a national key Torch Program by the National Ministry of Science and Technology, and sodium gluconate Program is rated as a national Spark Program project.
The company possesses its own professional quality engineer team and has established excellent quality assurance system and work procedures. It attaches much importance to and uses statistics quality management method to improve product and service quality and utilizes strict quality control. It successively imported several advanced test instruments including VARIAN from USA, SARTORIUS made in Germany and METTLER-TOLEDO with the origin of Switzerland, and achieved the goal to connect with the world both in hardware and software and meet customers’ demands in all ways.
By using its self import-export right, the company actively deals with electronic business. In recent years, its international business develops rapidly and business channels have been continually broadened. Currently, its business has spreaded to Europe, America, South Korea, Australia, and Japan, etc. Meanwhile, it has established close relations with worldly famous chemical corporations including BASF and Dow.etc.
After the rapid development in recent years, relying on the original fermentation advantages of the company, it has developed into a biochemical high-tech enterprises with gradually mature fermentation technology. At the same time, the company has strong research and development capacity of bio-chemical technology with abundant talent, advanced equipment. It will surely develop into an international renowned biochemical model through its strong scientific strength, excellent product quality and perfect sales channel.
