Product introduction：

The roller scraper dryer is a kind of rotating continuous drying equipment with internal heating conduction.

The rotating drum is attached to a thickness of the material film through its lower tank, and the heat is transported to the inner wall of the drum through the pipeline, and then transmitted to the outer wall of the drum, and then transmitted to the material film, so that the humidity in the material film can be evaporated and dehumidified, and the material with wet content can be dried.

The dried material is removed from the drum by a scraper installed on the surface of the drum to a spiral conveyor placed under the scraper, through which the dry material is concentrated and packaged.

Technical parameter：

Working principle：

Let the liquid or slurry material form a film on the surface of the drum heated by water vapor or other heat carrier, and it will be dried during the process of one turn of the drum. Use a scraper to scrape off the product, and the exposed surface of the drum will contact the raw material again and form a film for drying.

Product characteristics：

●  Large drying rate: because the material film is very thin, and the direction of heat and mass transfer is the same, the surface of the material film can be maintained 30-70kg... The vaporization strength of H2O(m².h);

●  Operation flexibility: wide adaptability, can adapt to a variety of materials and different production requirements;

●  High thermal efficiency: its general thermal efficiency is about 80-90%;

●  Short drying time: the drying cycle of the material is generally only 10-300 seconds, which is suitable for heat-sensitive materials. If the drum dryer is set in the vacuum, it can run under reduced pressure.
