Application

DWP type spray air mesh-belt drier/drying machine/drying equipment is mainly used for drying the fiber plate, plaster plate, paper case plate, pulp film, coated cloth and etc. The machine is also suitable for drying the sheet state material and some special materials

Principle

For DWP type spray air mesh-belt drying machine, the hot air flows, through narrow seams or holes, downward or upward to the materials on the transmission belt. Because the spray air speed is up to more than 15m/s, the heat transmitting film is very thin, the heat transmitting co-efficiency is big and the drying speed is fast. When the machine is used for the air tight grains, the above spray air flow will return go the top and the bottom spray air flow will return to the bottom. The air flows will be circulated. For some materials, the air flows will pass throough the inside of the materials. The heat source can be steam, electric, thermal furnaces and combustion oil and etc.
