Drum Scraper Dryer Equipment Overview
The drum scraper dryer is an internal heating conduction type rotary continuous drying equipment. The rotating drum adheres to the material film of a certain thickness through the lower material trough. The heat is transferred to the inner wall of the drum through the pipeline and is transferred to the outer wall of the drum. Parts of the material are dried. The dried material is shoveled away from the drum by a scraper mounted on the surface of the drum, to the screw conveyor placed under the scraper, and then the dry material is concentrated and packaged by the screw conveyor.
The roller scraper dryer is suitable for the drying of relatively viscous liquid materials in the chemical, dye, pharmaceutical, food, metallurgy, yeast and other industries. Widely used in: rice flour, oatmeal, alpha starch, potato powder and other dried food products into flakes, powders and granules.
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.

Features of drum scraper dryer
1. 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.
