Longradar offer approximate ten thousand of products of pressure, vacuum, flow, air velocity, temperature, humidity, level and valves, which are commonly applied in the fields of industrial automation, hvac, building autoimmunization control, electric power, petroleum, chemical industry, boilers, water treatment, compressors, freezing refrigeration, food brewage, pharmacy, light industrial, environmsent protec - tion, clean industry etc
在上游安裝一個帶有蛋形格柵的橢圓形流體噴嘴，可以提供一個精確構造簡單的空氣體積測量系統。在噴嘴的出口，空氣釋放時的風速分配是一致的靜壓為零。因此，噴嘴上游的總壓力是噴嘴出的速度壓力-於是就容易計算體積了。 -
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。 -
