PROBLEM TO BE SOLVED: To provide a drying system for rubber crumbs with the use of warm air which has an excellent effect to reduce the amount of heating steam to be used and exhaust gas by circulating/reusing air used for the warm air-drying. SOLUTION: In the drying system for the rubber crumbs with the use of the warm air, at least part of the warm air used for the drying is recycled to dry the rubber crumbs again. The warm air which is not recycled is discharged outside the system. The recycling rate (the ratio of the recycled warm air to the total amount of the warm air used for the drying) is preferably 10-70%. When the ratio is too small, the exhaust gas is not necessarily reduced. When the ratio is too large, the dying is not necessarily enough. COPYRIGHT: (C)2005,JPO&NCIPI |
