工作原理
在傳統(tǒng)的水平流廂式干燥器中，氣流只在物料表面流過，其缺點是傳熱系數(shù)低，熱利用率差，物料干燥時間長，且由于結(jié)構(gòu)的缺陷，無法完成符合 "GMP"藥品生產(chǎn)規(guī)范。為了克服以上缺點，我廠根據(jù)*進技術(shù)設(shè)計開發(fā)了穿流式箱式干燥器，其工作原理見圖:
Principle of work
The air steam passes through the surface of raw material only in traditional level chamber drier. The disadvantage is that the coefficient fo heat transfer is low and the utilization factor is poor and the drying time so long.Moreover because of the defect of sturcture,it can not be in conformity with the requirements of "GMP" .In order to overcome the shortcoming,we designed and developed the penetrating air stream box type drier on the basis of absorbing abroad advanced techonogy.The principle of work is shown in the figure listed below:

本機由風機將一部分新鮮空氣經(jīng)初，中·高三效過濾，達到十萬級凈化，經(jīng)蒸汽熱交換器，使空氣升溫至一定溫度，通過過濾器使熱空氣凈化后，再由左側(cè)分流板分至各層，使熱風平均通過每層被干燥的物料。濕空氣從烘盤底下的傾斜風道抽出后，經(jīng)離心風機使一部分濕空氣排出烘箱，另一部分空氣繼續(xù)循環(huán)加熱，達到干燥目的。
The fresh air is sucked through fan and then filterd through primary,secondary and high efficiency.Therefore the purification reaches to one hundred thousand grades.Through steam heat exchanger,the temperature of air is raised to certain temperature.The heated air is purified through filter again and then folws to every layer through left glow divider.It makes the hot air pass through the raw material to be dried evenly.The damp air is sucked from the inclined air channel under the drying tray.Pafrts of damp air are exhausted out off the oven through centrifuge fan and the other is circled and heated still. In this way the purpose can be realized.

熱性

熱風每一循環(huán)均通過亞高效或高效過濾器過濾，能有效避免空氣中夾帶物料在循環(huán)再加熱過程發(fā)生變質(zhì)，對藥品的污染，*符合“GMP"藥品生產(chǎn)規(guī)范。
穿流式烘箱比平流式烘箱干燥能力大，每層物料裝料厚度為平流式烘箱的三倍以上。
穿流式烘箱干燥面積大，效率高，能力比平流式烘箱大3-6倍，成本費用較低。
適合各種顆粒狀，塊狀物品的干燥。
操作容易，清洗更換便捷，故障率較低。
空氣進出口都有空氣過濾器，不會污染被干燥的物料，影響其品質(zhì)。
烘箱加熱熱源可采用蒸汽或電加熱。

Fetures
Because the hot air of each circle is filtered through sub-high or high efficiency filter,it can avoid effectively that the carried raw material in the
air is deteriouated and polluted during the period of re-circle and re-heating.It is in conformity with the requirements of "GMP" fully.
Compared with laminar flow type oven,the dry capacity is higher.The thickness of raw material to be dried is more than three times.
The dry afrea si large and the efficiency is high.Compared with level flow type ven.the capacity is more than 3-6 times.The cost is lower.
It is suitable for all kinds of raw materials having the shape of granule of block drying .
It is easy in operation and quick in clean and exchange and low in trouble.
There are air filters at inlet and outlet.The raw material to be dried can not be polluted and the quality of raw materials to be dried can not be damaged.
The heat source may be steam or electric heater.
