摘要
真空冷冻干燥(简称冻干)技术是一种现代化的高新干燥技术。由于是在低温及真空状态下完成对制品的脱水干燥,因而成为医学生物制品中首选的干燥保存方法。为此,介绍了药品冻干机自动装卸料系统的原理和结构,讨论了系统的控制方法,设计了系统的硬件模型和软件程序,阐述了PLC控制程序软件的设计与开发。
The principle and structure of the vacuum-freeze dryer loading and unloading system was introduced. The control method of the system was discussed. The hardware and software of the system was researched. Design and development on PLC control software were described in detail, which can realize the auto loading, and unloading function and auto manufacture process.
