Composite cereal drum scraper dryer

Compound cereal refers to cereal products made by mixing and processing multiple grains such as oats, wheat, barley, etc. It may also have added other ingredients such as nuts, dried fruits, seeds, etc. to increase nutritional value and taste diversity. This combination not only enriches the nutritional content of cereal, but also provides a more comprehensive range of dietary fiber, vitamins, and minerals.

OneComposite cereal drum scraper dryerOverview
The rotating drum of the drum scraper dryer adheres to a thick film of material through its lower chute, and heat is transported to the inner wall of the drum through pipelines, conducted to the outer wall of the drum, and then transmitted to the film, causing the humidity in the film to evaporate and dehumidify, and drying the material containing moisture. The dried material is removed from the drum by a scraper installed on the surface of the drum, and then transported to a screw conveyor placed below the scraper. The dry material is then collected and packaged by the screw conveyor.

IIComposite cereal drum scraper dryerprinciple
Composite cereal liquid or slurry like materials form a thin film on the surface of a drum heated by water vapor or other heat carriers. During one rotation of the drum, it is dried completely. The product is scraped off with a scraper, and the exposed surface of the drum comes into contact with the raw materials again to form a thin film for drying.

1. High drying rate: Due to the thin film and consistent direction of heat and mass transfer, the surface of the film can maintain a vaporization intensity of 30-70 kg · H2O (m ² · h);
2. High operational flexibility: Wide adaptability, able to meet the requirements of various materials and different production volumes;
3. High thermal efficiency: Its general thermal efficiency is between 80-90%;
4. Short drying time: The drying cycle of materials is generally only 10-300 seconds, which is suitable for heat sensitive materials. If the drum dryer is set in a vacuum chamber, it can operate under reduced pressure conditions.
