The Hot air circulation seaweed drum dryer is mainly composed of the front and rear supporting wheel device of the cylinder device, the feeding and discharging device, the transmission device and the gear cover.The drum dryer adopts a new type of lifting plate device, which has multiple functions such as guiding, equalizing, and lifting, which can make the material uniformly distributed in the radial section of the dryer, and the material curtain becomes thin, uniform and full. Fully contact the hot air flow to achieve the purpose of making full use of heat energy.
