摘　　要：首先论述了冷冻浓缩的原理、工艺种类及研究选择原则,并基于国内外现有的研究成果,采用悬浮式冷冻浓缩原理,针对特定料液构建了一套使用PLC自动控制的悬浮式冷冻浓缩中试装置。通过该中试装置进行工况测试、数据采集处理和试验结果分析,研究西瓜汁在冷冻浓缩过程中冷媒温度、刮刀转速和冷媒流量等对其结晶强度和冰晶纯度的影响,以便用于优化装置结构及操作运行参数等,使其能尽快得以工程应用和推广。This paper discusses frozen concentrated principle, craft category and researches choice principle. Based on existing research results at home and abroad, a frozen concentrated suspension pilot plant is build by using PLC automatic control for the specific feed solution. Through the working condition testing of pilot plant, data acquisition, processing and analysis of test results, the effects of the refrigerant temperature, drawknife turn and refrigerant flow to crystallization strength and ice crystal pure degree are researched. It is used for optimization to the device structure and the parameters of operation. Itcan apply to engineering application.
