Vacuum drying equipment tray dryer The dried material falls from the bottom drying tray to the bottom layer with cooling of the shell

The wet material is continuously fed into the pressure-resistant feeding hopper. After the material is distributed into the material tank through the upper vacuum ball valve, the upper and lower vacuum ball valves of the material tank are alternately opened and closed, and the material is continuously added to the upper first layer of the dryer under the action of the stirring motor for drying. On the plate, the rake arm with rake leaves rotates so that the rake leaves continuously turn over the material, so that the material can fully absorb heat, the material flows along the surface of the drying plate along the exponential spiral, and the material on the small drying plate is moved to the outside. At the outer edge, it falls to the outer edge of the large drying plate below. The material on the large drying plate moves inward and falls into the lower small drying plate from the middle blanking opening. The large and small drying plates are alternately arranged up and down, and the materials can be continuously flow through the entire dryer, and the heating medium is passed into the hollow drying tray. The heating medium enters the drying tray from one end of the drying tray, and is led out from the other end. The dried material falls from the bottom drying plate to the bottom layer of the shell with cooling, and then is moved by the rakes to the discharge port to discharge the bottom material tank, and is discharged through the upper and lower vacuum ball valves alternately switch. Moisture evaporates and evaporates from the material and escapes, and is forced out by a vacuum pump. The solvent is condensed by a condenser and enters the buffer tank for recovery. The whole operation process is carried out under negative pressure, and the moisture is emptied.
