The machine adopts honeycomb silica gel wheel for dehumidification. After the dehumidification effect is achieved, the dry air directly enters the heating chamber for heating (the heating temperature can be set according to different process requirements of different materials). Finally, it diffuses into the dynamic drying hopper in the form of 360 vortex air inlet from bottom to top, and at the same time, the materials are subject to low-speed rubbing (simulating the form of manual rubbing), Increase the looseness of materials, make each material evenly heated to the greatest extent, and complete dynamic drying.
