Lanzhou Kejin Vacuum Freeze Dry Technology Co. Ltd，systematically renamed after Kejin Technology Company of Institute of Modern Time Physics of Academy of Science of China， is a high-tech enterprise engaged in development of technology in food freeze drying and design，manufacture，installation and test of its facilities. Its key technological members are those who have worked long in research of heavy ion plasma accelerators and are well experienced both theoretically and practically in technological fields concerning food freeze dryers in mechanics, vacuum, refrigeration, thermal technique, electronics and automatic control.     The company was established in March 1999. Up to the end of March, 2008, 55 production lines have been installed in 18 provinces (cities), autonomous regions in China and in Russia and totally 141 JDG series food freeze dryers, over 30 small-sized freeze dryers have been sold, covering 21,339 square meters charging area (the total feeding area in China is 50,000 square meters) which is 42% of the marketing coverage.     In November 1994, our JDG-60 vacuum freeze dryer passed the appraisal by experts organized by Gansu Science Committee.     In December，2007 JDG-200F vacuum freeze dryer passed the appraisal of new scientific and technological products organized by Gansu Science and Technology Department and the appraisal organized by Gansu Economic Commission. The comment was “The technological level of series JDG freeze dryers has reached domestical leading level in the same kind of products and its energy preserving index has reached internationally advanced level.     In 2001 JDG series freeze dryer was placed by Ministry of Science and Technology into 《Guiding Program in the Plan to Popularize the Key National Scientific and Technological Products》 and 《State-level Torch Program in 2001》. In 2001 Certificate of National Key New Products was issued jointly by Ministry of Science and Technology and other 4 ministries and commissions. In December, 2002, the company passed ISO9001:2000 Quality-Management System Certification.     In November, 2007, our Small-Sized JDG Energy Conserving Freeze Dryers Project was awarded by Ministry Science and Technology nonreimbursable fund aid to scientific middle and small-sized creative enterprises.     At present we have already won two Firsts:     The first in marketing share in the same trade in China     The first in energy preserving in the same trade in China      Zhang Guanghua(the third from the left)，chairman of the company board is showing Wu Guanzheng (the second from the left)，the member of the Standing Committee of the Political Bureau of Central Committee of CCP our food vacuum freeze drying production line in Shanxian County, Shandong, China .   Zhang Guanghua (the first from the right), chairman of the company board is showing Li Xueyong (the one in the middle), vice minister of Ministry of Science and Technology our freeze drying laboratory and introducing the technique of food vacuum freeze drying.   Zhang Enhou (the first from the right), chief engineer of our company is showing Song Zhaosu (the first one from the left), Party secretary of Gansu Province freeze drying laboratory and introducing the technique of food vacuum freeze drying.   Zhang Enhou (the second from the right) research fellow of the company is showing Jiang Mianheng ( the first from the left), the vice chairman of the Academy of Sciences of China our freeze drying laboratory and introducing the technique of food vacuum freeze drying.   Zhang Guanghua (the first from the right) is showing Huang Kehua (the second from the left), deputy Party secretary of Shandong Province our food vacuum freeze drying introduction line in Lingshu, Shandong.   Zhang Guanghua (the first from the right), chairman of the company board is introducing the technique of food vacuum freeze drying to Hu Renyu (the second from the right), the academician and the leader from Sichuan Sciences Commission.     Pu Qingyu, (the first from the right) is introducing the technique of food vacuum freeze drying to Wang Jingchuan (the second from the right), deputy director of State Bureau of Intellectual Property.
