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 of the heat transfer is low and the utilization factor is poor and the drying time so long.In order to overcome the shortcoming,we designed and developed the penetrating air stream box type drier on the basis of absorbing abroad advanced technology.The principle of work is shown in the figure listed below:
1.filter for damp discharge
2.filter for fresh air
3.heater
4.drying trolly
5.sub-high(high)efficiency filter
6.flow leading piece
7.centrifugal fan
8.pressing mechanism for air suction
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 flows 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.Parts 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.
Features
1. 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.
2. Compared with laminar flow type oven,the dry capacity is higher.The thickness of raw material to be dried is more than three times.
3. The dry area is large and the efficiency is high.Compared with level flow type oven,the capacity is more than 3-6 times .The cost is lower.
4. It is suitable for all kinds of raw materials having the shape of granule of block drying.
5. It is easy in operation and quick in clean and exchange and low in trouble.
6. There are air filters at inlet and outet.The raw material to be dried can not be polluted and the quality of raw materials to be dried can not be damaged.
7. The heat source may be steam or electric heater.
