冷冻干燥是将某种物质的溶液经冷冻固化,通过减压升华除去溶剂的一种物理过程。现介绍一种较为简易的冷冻干燥装置,凡是有低温冰箱的医院即可装置生产冷冻干燥制品,效率较高。本装置结构如附图。 Freeze-drying is a physical process by which a solution of a substance is freeze-cured and the solvent is removed by depressurization and sublimation. Now introduce a more simple freeze-drying device, any hospital with a low-temperature refrigerator device can be installed to produce freeze-dried products, high efficiency. The device structure as the picture.
