Disc Dryer

The disc dryer is a contact dryer used to extract dry matter from liquids containing solid particles, such as solutions and suspensions. The liquid to be dried is sprayed onto a set of discs heated by steam from the center through a pump and multiple nozzle bodies. The liquid evaporates on the surface of the heated discs. After the remaining dry matter has rotated once, it is scraped off the surface of the disc by a scraper located on the disc. The resulting dry material is transported out of the dryer by a conveying device. After that, the exhaust gas containing water vapor is discharged. Therefore, the heat energy consumption of this dryer is relatively low.

Disc dryers have particular advantages in terms of energy consumption. The structure and design of the disc pack makes it significantly more compact than other similar contact dryers, such as drum scraper dryers. In addition, the heat transfer capacity per square meter of heated surface is also higher than that of drum dryers.

Application
1. Industrial wastewater, ceramic suspensions and ceramic glazes, salt solutions, paints.
2. Kaolin slurry, bentonite slurry, resins, brewery wastewater.
3. Yeast suspension, egg liquid, gel, fish farming wastewater, spray paint wastewater, hydroxides.
4. Silicates, concentrated working fluids of tin, zinc, tungsten, nickel, etc., and others, graphite.
5. In addition to being used to extract dry substances from liquids, it can also evaporate part of the liquid for concentration. Disc dryers are also a reliable alternative to vertical thin film evaporators.

Structure drawing


Liquid is supplied to the Disk surface
The raw liquid from the circulation tank is pumped to the disk through the liquid inlet pipe. The liquid spreads into a thin film, which improves the heat transfer efficiency. The excess solution returns to the circulation tank and is pumped again.


Drying 
The solution attached to the surface of the heating disk is dried as the disk rotates. By changing the rotation speed of the disk and the steam pressure (drying temperature), the processing capacity and the moisture content of the dried product can be adjusted.


Dry material collection
The scraper scrapes the product off the disc surface. The scraper continuously cleans the disc surface (heat exchange surface) to maintain good heat conductivity
Compact structure
The space saving of the disc dryer is about 40% of that of a twin-drum dryer with the same heat transfer area.


Comparison of dryers
1. Disc dryers are unique in many other ways.
2. Compatible with a wide range of applications, including powder production, drying/concentrating and recycling of waste liquids.
3. Save space and reduce installation costs by using one unit to dry and pulverize all types of liquids (organic or inorganic).
4. Dry waste liquids to reduce their volume.
5. Sell and profit from recovered resources such as precious or rare metals.
6. Protect the global environment while reducing costs for your business.
