This lift type stirring dryer adopts high-efficient sorbent, very suitable to resolve many problems in engineering plastic, such as short intension, size error, bad shine and etc. By means of chemcial drying principle, air with high water percentage is extracted out. When the air passes tank, water is absorbed completely. Dewatered dry air is heated to set temperature and sent into fry tank. The dry air absorb water remained in plastic very quickly. This air is extracted out from tank again. After processed in cooler and heated, it is changed into dry hot air again. Therefore the same processes go on again and again to realize dahunmidifying purpose.
