工作原理
在传统的水平流厢式干燥器中,气流只在物料表面流过,其缺点是传热系数低,热利用率差,物料干燥时间长,且由于结构的缺陷,无法完成符合 "GMP"药品生产规范。为了克服以上缺点,我厂根据*进技术设计开发了穿流式箱式干燥器,其工作原理见图:
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:
本机由风机将一部分新鲜空气经初,中·高三效过滤,达到十万级净化,经蒸汽热交换器,使空气升温至一定温度,通过过滤器使热空气净化后,再由左侧分流板分至各层,使热风平均通过每层被干燥的物料。湿空气从烘盘底下的倾斜风道抽出后,经离心风机使一部分湿空气排出烘箱,另一部分空气继续循环加热,达到干燥目的。
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.
热性
热风每一循环均通过亚高效或高效过滤器过滤,能有效避免空气中夹带物料在循环再加热过程发生变质,对药品的污染,*符合“GMP”药品生产规范。
穿流式烘箱比平流式烘箱干燥能力大,每层物料装料厚度为平流式烘箱的三倍以上。
穿流式烘箱干燥面积大,效率高,能力比平流式烘箱大3-6倍,成本费用较低。
适合各种颗粒状,块状物品的干燥。
操作容易,清洗更换便捷,故障率较低。
空气进出口都有空气过滤器,不会污染被干燥的物料,影响其品质。
烘箱加热热源可采用蒸汽或电加热。
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.
