JCT Series Special Drying Oven

 Principle                                      
The air steam passes through only the surface of raw material in traditional chamber drier. The disadvantage is that the coefficient of raw material only in traditional level chamber dryer. The disadvantage is that the coefficient of heat transfer is low, the drying time is long, and it has defects in structure, can not be in conformity with the requirements of "GMP". In order to over-come the shortage, we designed and developed the penetrating air stream chamber dryer on the basis of absorbing foreign advanced technology. The principle of work is shown in the diagram below. 
The fresh air is sucked by fan and then filtered by pre, post and sub-high efficiency to achieve 10,00 grade clean effect. Pass through steam heat exchanger the temperature of air rises to certain temperature. The heated air passes through flow distributor enters every layer, passes through each layer of raw material to be dried, humid air is exhausted through the inclined air channel under the drying tray. Part of the air circulates in the system. 

    

Feature

1.To avoid pollution of product caused by circulation air, all circulation air passes through post or high efficiency filters. It is in conformity with the requirements of GMP.
2.Compared to traditional horizontal chamber dryer, its capacity of drying is larger. The thickness of raw materials each layer can be over three times. 
3.Compared to traditional horizontal chamber dryer, its drying area is large and its efficiency is high. Its capacity of drying might be several times higher, the cost is reasonable.
4.Applicable to dry various kinds of granules and block of materials. 
5.Easy in operation, convenient in parts exchanging, low in faults. 
6.There are air filters at air inlet and air outlet. Therefore the dried raw materials can’t be polluted and the quality of product can’t be effected. 
7.The hot source can adopt steam , oil or electric heater.
