| 摘 要： | 采用电阻法测量了生姜的共晶点和共熔点温度，其值分别为-13℃和-12℃。在实验室冻干机上进行了正交试验，结果表明：真空冷冻干燥过程中加热方式、加热温度、干燥室压力以及物料厚度等因素对冷冻干燥速率均有影响，影响程度依次为：物料厚度＞加热板温度＞干燥室压力。

| Abstract: | A set of experiments designed by the orthogonal method was carried out on a lab scale vacuum freeze dryer and the freeze drying characteristics of gingers, such as the temperatures of eutectic and co melting points, were measured during the experiments. The analysis of the experimental results showed that the main influencing factors of freeze drying were heating temperature, material thickness and pressure of drying chamber. The sequence of importance were material thickness, heating temperature and pressure of chamber respectively |
