The disc drier is a drying device which is developed by integrating a series of advanced technologies and continuously improving on the basis of an intermittent stirring and conducting drier, is a multi-layer fixed hollow heating circular material carrying disc, is stirred by a rotary rake, and is vertical and continuous and mainly used for heat conduction. The drying process is that heat carrier is introduced into hollow discs in different layers to heat wet material on the disc surface indirectly in heat conducting mode, and under the action of the rotating rake blades, the wet material in the material is evaporated at operation temperature and the vapor is exhausted with tail gas from the apparatus to obtain qualified dried product continuously in the bottom of the apparatus.

The wet material is continuously added to the first layer of drying disk on the upper part of the dryer from the feeder, and the rake arm with the rake blades rotates to enable the rake shovel to continuously turn over and copy the material. The material flows over the surface of the drying tray along an exponential spiral line, the material on the small drying tray is transferred to the outer edge and falls to the outer edge of the large drying tray below at the outer edge, and the material on the large drying tray moves inwards and falls into the next small drying tray from the middle blanking port.
