Applications:
DWP type spray air mesh-belt drying machine is mainly used for drying the fiber plate, plaster plate, carton board, 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 air jet mesh-belt dryer, 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 air jet flow will return to the top and the bottom flow will return to the bottom, take part in circulation. For some materials, the air flows will pass through the inside of the materials, the heat source can be steam, electricity, thermal furnaces and combustion oil flue and etc.
