The results indicate that drying thickness , radiant temperature and pressure of drying chamber are the most three significant factors . there ' s hardly any relationship between freezing rate and drying time , the sublimation drying time of slow freezing material is shorter than quick freezing one , but its desorption drying time is relatively longer , so the total drying time is approximately the same . the initial freezing temperature and freezing manner has little influence on vacuum freeze drying process
试验表明：冻干厚度、加热板温度、系统的真空度是最重要的三个过程参数；冻结速率对总冻干时间没有影响，慢冻物料的升华干燥时间要比快冻物料短，但慢冻的解析时间相对较长，两者的总冻干时间相差很小；初始冻结温度对冻干过程的影响可以忽略。
