in addition, when the wet materials are gradually dried and moved into the exhaust gas bin 104, the wet materials do not enter the exhaust gas bin 104 to block the exhaust gas pipe 2 because of the limitation of the shape of the arc-shaped coordination plate 1001, but the exhaust gas generated therein can be discharged through the air-permeable and water-permeable membrane 9 thereon, and the arc-shaped coordination plate 1001 does not interfere with the normal rotation of the heat supply tub 6.
