板長厚比參數
英文
plate slenderness parameter-
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
試驗表明：凍干厚度、加熱板溫度、系統的真空度是最重要的三個過程參數；凍結速率對總凍干時間沒有影響，慢凍物料的升華乾燥時間要比快凍物料短，但慢凍的解析時間相對較長，兩者的總凍干時間相差很小；初始凍結溫度對凍干過程的影響可以忽略。During the analysis, three non - dimensional parameter is considered : the ratio of the inserting depth of steel pipe to plate ; the ratio of the length of plate to the width of plate ; the ratio of the width of plate to the thick of plate
分析時考慮了三個無量綱參數，鋼板插入鋼管深度lw與鋼管直徑之比;鋼板長度與鋼板厚度之比;鋼板寬度與鋼板厚度之比。
