Drum Scraper Dryer Equipment
The drum scraper dryer is an internal heating conduction type rotary continuous drying device. The rotating drum is adhered to a film of a thickness through the lower trough, and the heat is transported to the inner wall of the drum through the pipeline, and is conducted to the outer wall of the drum, and then the feed film is transferred, so that the humidity in the film is evaporated and dehumidified. The moisture-containing material is dried. The dried material is scraped off the drum by the scraper attached to the surface of the drum, to the screw conveyor placed under the scraper, and the dry material is concentrated and packaged by the screw conveyor.
Working principle of roller scraper dryer
Drying process: Let the liquid or muddy material form a film on the
surface of the drum heated by steam or other heat carriers. The
drum is dried in one revolution. The product is scraped off with a
scraper, and the exposed surface of the drum comes into contact
with the raw material again. And form a film to dry.
The drum scraper dryer uses a certain method to spread the liquid
or pasty material on the drum (hollow metal cylinder) with a
0.1-1.5mm film. The drum can be heated with steam, hot water or
thermal oil. When the drum rotates once, the material can be dried
and scraped off the surface of the cylinder by a special scraper.
The drum scraper dryer generally rotates at a speed of 4 to 6 rpm.
The drying of the paste-like material is to adjust the thickness of
the material and to compact the material layer. On the side close
to the feeding device, a material compression shaft is installed to
make the material evenly spread on the drum. In order to make the
material easier to fall off when the scraper discharges the
material, before the scraping, the cold air pipe can also be used
to blow a certain amount of cold air to cool the material.

Applications
It can quickly dehydrate and dry materials with high humidity to achieve the effect of turning waste into treasures. It is one of the most important dehydration and drying equipment in the drying industry. It is suitable for drying liquid and viscous materials in chemical, dye, pharmaceutical, food, metallurgy, yeast and other industries.
Features of drum scraper dryer
Large operation flexibility and wide adaptability, the operation
flexibility of the drum dryer is very large, and can adapt to the
requirements of multiple materials and different output;
2. The thermal efficiency of the roller scraper drying is high;
3. The drying time is short, the wet material film of the material
to be dried on the outer wall of the drum is generally 0.3 to 1.5
mm, and the entire drying cycle takes only 10 to 60 s;
4. Large drying rate: Because the material film is very thin, the
surface of the material film can maintain the drying strength of
15-50kg water/m2h;
5. Continuous operation, stable quality, labor saving, and uniform
product can be obtained;
6. The inside of the machine is easy to clean, and it is easy to
change the variety;
7. Exhaust gas does not take away materials, and no dust removal
equipment is required.
