Granule drier

The invention discloses a granule drier. The granule drier comprises a barrel, a blower, a heater and a cyclone separator, wherein a granule distribution grating plate is arranged in the barrel; 3-6 notches are uniformly distributed at the circumferential lower part of the granule distribution grating plate; clamp tables matched with the notches are arranged on the inner wall of the barrel; a rotatable limit block is arranged on the upper surface of each clamp table; the limit blocks are rotated to be located in or extend out of an edge on the upper surface of the corresponding clamp tables; afeed pipe and a discharge pipe are respectively arranged on two opposite sides of the side wall of the barrel; an air inlet is formed in the bottom of the barrel; an air outlet is formed in the top of the barrel; the blower is connected with an inlet of the heater through an air inlet pipe; an outlet of the heater is connected with the air inlet; the air outlet is connected with an inlet of the cyclone separator through an air outlet pipe; and a gas outlet of the cyclone separator is connected to the air inlet pipe in a returning manner. Under the action of hot air, granules are in a boilingstate, so that moisture on the surfaces of the granules is quickly taken away, and accordingly, the granules are dried. Waste heat is recycled, so that the energy consumption is low.
