The wet material self-feeder is continuously added to the drying disc of the first layer of the drying machine, and the rake arm with the rake blade is rotated so that the rake arm is rotated so that the rake blade is continuously turned over the material. The material flows through the surface of the drying tray along the exponential helix. 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. The material on the large drying tray moves inward and falls to the next small drying tray through the middle blanking port. The size of the drying tray is arranged alternately up and down, so that the material can flow continuously through the entire dryer. The heating medium in the form of saturated steam, hot water, heat conduction oil and high temperature molten salt is passed into the hollow drying tray. The heating medium enters from one end of the drying tray and is exported from the other end. The dried material falls to the bottom of the shell from the last drying tray and is finally transferred to the discharge port by the rake leaf. The moisture overflows from the material and is discharged through the moisture discharge port on the top cover. The moisture of the vacuum disc dryer is discharged through the vacuum pump port on the top cover. Dry material discharged from the bottom layer can be packaged directly. By adding fin heater, solvent recovery condenser, bag dust collector, dry material remixing mechanism, induced draft fan and other auxiliary machines, it can improve its drying production capacity, dry paste and heat sensitive materials, can easily recover solvent, and can carry out pyrolysis and reaction operations.
