Drying device for seedling-culture nutrition blocks

The utility model discloses a drying device for seedling-culture nutrition blocks, which comprises a drying drum, a screw conveyor belt, a feed conveyor, a discharge hole and a marsh gas delivery pipe. The drying device is characterized by further comprising an induced draft fan, a marsh gas combustion chamber, an electrical control cabinet and a marsh gas generating set, wherein the marsh gas generating set generates power through the marsh gas delivered through the marsh gas delivery pipe and is connected with the electrical control cabinet; the electrical control cabinet outputs electric power for driving the drying drum to rotate; and the seedling-culture nutrition blocks are dried by using heat generated marsh gas burning. The drying device has the advantages that the heat generated marsh gas burning is in direct contact and mixed with the seedling-culture nutrition blocks by adopting the direct drying technology, and the seedling-culture nutrition blocks are dried by the heat generated during marsh gas burning and through marsh gas power generation, and is simple to operate.
