Working process of  rotary air dryer

The rotary air dryer is a type of industrial dryer employed to reduce or minimize the moisture content of the material. It is handling by bringing it into direct contact with a heated gas. The rotary air dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The rotary air dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through rotary air dryer under gravity. Material to be dried enters the rotary air dryer, and as the rotary air dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the rotary air dryer.When the material gets high enough to roll back off the fins, it falls back down to the bottom of the rotary air dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the rotary air dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the rotary air dryer.The rotary air dryeras an indirect-heated type. Often, indirect heated rotary air dryer is used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary air dryeris also available to improve the overall efficiency.
