Disc continuous dryer is a highly efficient conductive continuous drying equipment. The heat medium transfers heat to the heated material through the heat exchange of the partition wall, which greatly reduces the participation of hot air, simplifies the system, and obtains a very high thermal efficiency.

The disc continuous dryer is a multi-layer hollow disc structure, and the wet material is continuously added to the first drying disc on the upper part of the dryer, and the rake arm with the rake leaves rotates so that the rake leaves continuously turn over the material. The material flows through the surface of the drying plate along an exponential spiral, and falls to the drying plate below one by one. The large and small drying trays are arranged alternately up and down, so that the material can continuously flow through the entire dryer. A heating medium such as saturated steam, hot water, heat transfer oil or high-temperature molten salt is passed into the hollow drying plate. Dried materials fall from the bottom layer of the drying plate to the bottom layer of the shell, and are finally moved by the rake leaves to the discharge port for discharge. 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 from the vacuum pump port on the top cover. The solvent can be easily recovered by adding a condenser. Adding auxiliary equipment such as fin heater, bag filter, induced draft fan, etc. can improve its drying production capacity. The tray dryer can also perform pyrolysis and reaction operations.

Features

1. Easy to control, strong applicability, and very simple to start and stop operations.

2. Each layer of drying tray can be fed with hot/cold medium separately, and the material temperature can be controlled accurately.

3. The residence time of the material can be adjusted accurately.

4. Single material flow direction, no back-mixing phenomenon, uniform drying and stable quality.

5. After stopping the feeding, the rake blades that convey the material can quickly empty the material in the dryer.

6. Through the special large-size inspection door and sight glass, the inside of the equipment can be carefully cleaned and observed.

7. The material layer is very thin, the spindle speed is low, the system installed power is small, and the power consumption is low.

8. The operating environment is good, the solvent can be recycled, and the exhaust dust content is very low.

9. It can be operated under vacuum, especially suitable for drying heat sensitive materials.

10. The dryer is delivered as a whole, and only needs to be hoisted in place, which is very easy to install and locate.

11. Drying trays are arranged in layers and installed vertically, occupying a small area.

Operating procedures

Basic configuration disc continuous drying process

The wet material is uniformly added to the top of the disc continuous dryer through a quantitative feeder, and the drying process is completed when flowing through the dryer from top to bottom, and the dry material is discharged from the bottom of the dryer. The moisture escaping from the material is discharged into the atmosphere through the moisture outlet on the top of the dryer.

Optional disc continuous drying process

On the basis of the basic configuration, according to the different drying requirements of different materials, some auxiliary settings can be added to achieve a better drying effect:
