Wet material from the feeder continuously added to the dryer on the first layer of the upper drying disc, with a rake leaf rake arm for rotary movement so that the rake arm for rotary movement so that the rake leaf continuous plunge material. The material flows through the surface of the drying disc along the index helix, and the material on the small drying disc is moved to the outer edge, and falls to the outer edge of the large drying disc below the outer edge of the large drying disc, and the material on the large drying disc moves inwardly and falls down to the next layer of small drying discs from the middle of the material falling mouth. The size of the drying discs arranged alternately up and down, the material to flow continuously through the entire dryer. The hollow drying disc passes into the heating medium, the form of heating medium has saturated steam, hot water and heat-conducting oil, the heating medium enters from one end of the drying disc, and leads out from the other end. The dried material falls to the bottom of the shell from the latter layer of drying disc, and then is moved to the discharge port by the rake leaves. Moisture escapes from the material, and is discharged by the moisture discharge port located on the top cover, and the moisture of the vacuum-type disc dryer is discharged by the vacuum pump port located on the top cover. The dry material discharged from the bottom can be packed directly. By adding fin heater, solvent recovery condenser, bag-type dust collector, dry material re-mixing mechanism, induced draft fan and other auxiliary machines, it can improve its drying production capacity, drying paste and heat-sensitive materials, can be convenient to recover solvents, and can carry out pyrolysis and reaction operations.

Equipment features

(I) Easy regulation and strong applicability
◎The drying process can reach the state by adjusting the thickness of material layer, the rotating speed of main shaft, the number of rake arms, the type and size of rake leaves.
◎ Each layer of drying disc can be individually heated or cooled by entering hot medium or cold medium, and the temperature of material can be controlled accurately and easily.
The residence time of material can be adjusted precisely.
The flow direction of the material is single, no mixing phenomenon, even drying, stable quality, no need to mix again.
(II) Simple and easy operation
◎The start and stop operation of the dryer is very simple.
After stopping the feeding, the rake blade which transfers the material can empty the material in the dryer very quickly.
◎ Through the special large inspection door of the sight glass, can be very carefully cleaned and observed inside the equipment.
(C) Low energy consumption
◎The material layer is very thin, the main shaft rotational speed is low, the power required for the material transfer system is small, and the electricity consumption is low.
◎ Drying by conduction heat, high thermal efficiency, low energy consumption.
(D) good operating environment, solvent recovery, dust emissions in line with requirements
Atmospheric pressure type: Due to the low speed of airflow in the equipment, and the humidity distribution in the equipment is high and low, it is difficult for the dust to float to the top of the equipment, so the exhaust gas discharged from the humidity discharge port at the top almost does not contain dust.
◎ Closed type: Equipped with a solvent recovery device, the organic solvent in the moisture-carrying gas can be easily recovered. The solvent recovery device is simple, with high recovery rate. For flammable, explosive, toxic and oxidising materials, nitrogen can be used as the humidity-carrying gas for closed-circuit recycling, making it safe to operate. It is especially suitable for the drying of flammable, explosive and toxic materials.
◎ Vacuum type: disc dryer operated under vacuum, especially suitable for drying heat-sensitive materials.
(E) Convenient installation and small floor space
◎The dryer is shipped as a whole, transported as a whole, and only needs to be lifted into position, so it is very easy to be installed and positioned.
◎ Because of the drying disc layer arrangement, vertical installation, even if the drying area is very large, covers an area of very small.
