冷冻干燥机(简称冻干机)用于生物制品、药品、血液制品……等进行冷冻干燥,干燥后的制品,具有原有的物理化学性质,可保持原有的体积,冻干后成疏松的海绵状,保存期长,并有复水快的特点。特别适用于热敏感物质的干燥。在国内工业用冻干机制冷系统大都采用1/3FV7B单机双级半封闭制冷压缩机,该压缩机属于70系列产品,它有三个低压缸,一个高压缸,缸径70mm,行程60mm,转速1450r/min,配10kW的耐
Freeze-drying machine (referred to as freeze-drying machine) for biological products, pharmaceuticals, blood products ... ... and other freeze-dried, dried products, with the original physicochemical properties, to maintain the original volume, Sponge-like, long shelf life, and fast water complex features. Particularly suitable for heat-sensitive material drying. In the domestic industrial freeze dryer refrigeration system mostly adopt 1 / 3FV7B stand-alone two-stage semi-enclosed refrigeration compressor, the compressor belongs to the 70 series of products, it has three low pressure cylinder, a high pressure cylinder, bore 70mm, stroke 60mm, speed 1450r / min, with 10kW resistance
