本文从理论分析入手,参考在研制 DLGJ 型和 ZLG-5型真空冷冻干燥机中所测试的数据,分析影响直接制冷、间接加热式搁板的温度均匀性的因素,从而进一步探讨提高搁板温度均匀性的途径和设计方法。
Starting from the theoretical analysis, this paper analyzes the data of the DLGJ and ZLG-5 vacuum freeze-dryers and analyzes the factors that affect the temperature uniformity of the direct-cooling and indirect-heating shelves, so as to further explore how to raise the shelf temperature The way of uniformity and design method.
