Can use coal, electricity, steam as heat source, drying temperature, speed, full automatic control. Material in the dryer, a circulation fan will air waft into drying materials. The dryer has the platoon is wet system to exclude moisture in time, to achieve the purpose of drying.

Belt drier belongs to the jet stream type belt drying, hot air to hole beam by top and bottom spray to the conveyor belt of logistics at the same time, because of the jet gas velocity is up to more than 15 m/s, so the convection heat transfer of film to a very thin, heat transfer coefficient is big, fast drying speed. DWF series belt drying machine is used for airtight class material, the jet stream is still to return to the above, the following exhausts still return below, in the loop. Of air permeability material has strong penetrability and internal diffusivity in the material. Using the heat source can be steam, electric heating, hot blast stove and flue gas fuel oil, etc. DWF type jet stream belt drying machine is mainly used for fiber board, gypsum board, carton board, pulp film, coating and drying, etc., can also be applied to dry flake material and some special material.
