■ Raw material will be loaded on trays and put on trolley. Driven system will transfer trolleys into tunnel oven. Conveying speed of trolleys is adjustable. Fresh air get into centrifuge fan through air window. After being heated by heat exchanger hot air will blow into tunnel oven chamber and fully contact with wet raw material. After exchanging thermal heat, moisture in wet material will be evaporated into vapor. Vapor will get into side air chamber together with hot air, then some part of vapor will exhaust outside through exhaust window, the other part vapor will be absorbed by centrifuge fan and recycle used in drying system.As in each drying section, water content of raw material is different, so in each dryer section exhausting air and circulating air ratio is different; during whole drying process, drying temperature for each drying section is different too; at primary drying process, because water content of raw material is high, so we should design higher temperature hot air ; but at end drying process water content of raw material is lower, so we should design lower temperature hot air for this section.

 

Features

 

■ According to the features of raw material, thecustomer can choose the drying method of either vertical or horizontal circle, in order to  enhance the efficiency and quality of product.
