【Abstract】 With the basic theories of fluid mechanics being applied) the air velocity and temperature distributions in the relevant fields in the drying room of a heated air dryer were intensively analyzed. Furthermore, a structure scheme of the drying room was advanced to enable the even distributions of the air velocity and temperature in the fields to be obtained. Meanwhile, an experimental study on the Model ST-1 chest-type two-direction flow heated air dryer was carri e d out. It was found possible and practical to utilize the scheme in this kind of dryers, and the scheme can be taken as reference in the designing and studying for this kind of dryers.更多还原
