为了确定荔枝真空冷冻干燥的工艺参数,采用电阻法测量荔枝真空冷冻干燥的物料共晶点,并应用响应面法,以冻干品生产能耗为指标进行评定考察冻干效果,优化荔枝真空冷冻干燥工艺。结果表明:荔枝真空冷冻干燥物料的共晶点温度为-23℃,干燥室压力为60Pa、物料厚度为4mm、加热温度为35℃,应用该优化技术工艺可最大限度地降低生产能耗。
Abstract：In order to confirm the optimum technological parameter in vacuum freeze-drying of litchi,experiments were conducted with litchi.The eutectic point of litchi was determined by electrical resistance method in the vacuum freeze-drying.The technologies of the vacuum freeze-drying of litchi were optimized by Response Surface Methodology,and according to evaluating the effects of the energy consumption indexes in the process.The results showed that the eutectic point of litchi pulp materials were-23℃ in the vacuum freeze-drying.The optimized combination of factors is pressure of drying house 60pa,material thickness 4mm,heating temperature 35℃.With the application of the technology to the optimization of the maximize production energy consumption.
