【摘要】：真空冻干机是一种利用冷冻真空干燥技术的化工过程装备,其应用十分广泛。但相比于国外技术而言,国产设备在生产效率、能耗等级、设备可靠性上仍有较大的差距。因此,为提高设备的可靠性,本文结合冻干机发展趋势,采用先进的现代设计方法设计了一台真空冻干机,并对核心部件进行了分析研究。本研究首先确定了 Ray125型真空冻干机的整体设计方案,并对整个系统参数进行了理论分析和计算。在此基础上,对干燥罐、冷凝器进行了常规设计,并使用有限元分析软件行了设计研究和设计验证;同时基于弹性分析设计方法,对加热板和冷凝器进行了的分析设计研究。为进一步提高设计的可靠性和安全性,对干燥罐进行了失稳分析,对冷凝器进行了疲劳分析。本文设计的真空冻干机已成功应用于实际生产,并已交付客户用于咖啡的冻干,且实现了两年无故障的运行。
[Abstract]:Vacuum freeze drying machine is equipped with a chemical process using the vacuum freeze drying technology, its application is very extensive. But compared with foreign technology, domestic equipment in the production efficiency, energy consumption level, there is still a large gap between the reliability of the equipment. Therefore, in order to improve the reliability of the equipment, combining with the development trend of the lyophilizer, the modern advanced design method to design a vacuum freeze drying machine, and the core components are analyzed. This study first determine the overall design scheme of Ray125 type vacuum freeze drying machine, and the system parameters are analyzed and calculated. Based on this, the drying tank, condenser were conducted. Design and the design research and design verification using finite element analysis software design method based on elastic analysis; at the same time, the research on the analysis and design of the heating plate and the condenser. In order to further improve the design The reliability and safety of the drying tank were analyzed. The fatigue analysis of the condenser was carried out. The vacuum freeze-drying machine designed in this paper has been successfully applied to the actual production, and has been delivered to the customers for coffee freeze-drying, and it has been running for two years without fault.
