介绍了原料药真空干燥工艺。结合有机溶剂的特点,分析了传统湿式真空系统在回收有机溶剂方面的局限性。介绍了干式真空泵的结构和优点。提出了干式真空冷凝系统的概念,并对系统组成部分(干式螺杆真空泵、真空管路和冷凝器等)的设计、选型作了介绍。
Introduced the raw material vacuum drying process. Combined with the characteristics of organic solvents, the limitations of traditional wet vacuum systems in the recovery of organic solvents were analyzed. The structure and advantages of dry vacuum pump are introduced. The concept of dry vacuum condensing system was put forward and the design and selection of system components (dry screw vacuum pump, vacuum circuit and condenser) were introduced.
