The wet material is continuously fed from the feeder to the first layer of the drying tray on the upper part of the dryer, and the rake arm with the rake leaves rotates to make the rake arm rotate, so that the rake leaves continuously turn over the material.
The material flows over the surface of the drying tray along the exponential spiral, the material on the small drying tray is moved to the outer edge, and falls to the outer edge of the large drying tray below, on the large drying tray, the material moves inward and falls from the middle. The material mouth falls into the following layer of small drying trays.
The large and small drying trays are arranged alternately up and down, so that the material can flow through the entire dryer continuously. A heating medium is introduced into the hollow drying pan, and the heating medium is in the form of saturated steam, hot water and heat-conducting oil. The heating medium enters from one end of the drying pan and is led out from the other end. The dried material falls from the bottom drying tray to the bottom layer of the shell, and is then moved by the rakes to the discharge port for discharge.
The moisture escapes from the material and is discharged from the moisture outlet on the top cover, and the moisture in the vacuum type disc dryer is discharged from the vacuum pump port on the top cover.
The dry material discharged from the bottom layer can be packed directly. By adding auxiliary machines such as fin heater, solvent recovery condenser, bag filter, dry material back-mixing mechanism, induced draft fan, etc., its drying production capacity can be improved, and drying paste and heat-sensitive materials can be easily recovered. Solvent, and can carry out pyrolysis and reaction operations.
