上海生物化学制药厂为生产酶、蛋白质激素等生化药品的专业工厂,成品均以冻干制剂出厂,因此冻干机成为本厂的关键设备。1981年对国内外冻干机作了调研,并对各种导热液进行了试验,解决了冻干机用的导热液。82年初设计和制造了8.1m~2冻干机。于82年6月试运转,8月份投产。干燥时间由原来36小时缩短为22小时。每箱产量为2ml安瓿6万支。现将该机的设计和实践作一介绍。 Shanghai Biochemical Pharmaceutical Factory is a specialized factory producing biochemical drugs such as enzymes and protein hormones. The finished products are all manufactured by freeze-dried preparations. Therefore, the freeze-drying machine has become the key equipment of our factory. In 1981 the domestic and international lyophilizer made a research, and conducted a variety of thermal fluid test, to solve the lyophilizer with thermal fluid. 82 early in the design and manufacture of 8.1m ~ 2 freeze dryer. Commissioned in June 82, commissioning in August. Drying time reduced from 36 hours to 22 hours. The output of each box is 2ml ampoules 60,000. Now the machine design and practice for an introduction.
