In this paper, via analysis and research on the actual working situation of JK3 type vacuum concentrating equipment we have found that reasons of the reduced function of working are the result of that the vacuum degree of work cuts down and isn't suitable with the temperature of heating and the heat cycle in each evaporator.
本文通过对 JK3型真空浓缩设备工作性能的研究分析表明 :导致其生产能力和蒸发量减少 ,能耗增加 ,蒸发温度升高 ,产品质量下降的主要原因是各效蒸发器工作真空度下降 ,加热温度和热循环与其不相匹配所致。
