Working principle

Drum Dryer is a kind of internal heating conduction type rotating drying equipment, wet material on the outer wall of the drum to obtain heat transfer method to remove moisture, to achieve the required wet water content. Heat from the tube wall to the outer wall of the tube, and then through the material film, its high thermal efficiency, can be continuously operated, it is widely used in liquid materials or strip material drying, paste and viscous materials more suitable. Can be divided into two kinds of forms: single-cylinder, double-cylinder dryer. In addition, the operating pressure can also be divided into two forms of normal and decompression.

Features and application
flexible operation, wide adaptability, can adapt to a variety of materials and different production
requirements.
The thermal efficiency is high, the general thermal efficiency is about 80%-90%.
Short Drying time: drying materials on the outer wall of the drum can be formed at the start of drying wet material film is generally 0.5-1.5mm, the entire drying period is only 10-15s, especially for thermal sensitive materials.
High drying rate: Because the film is thin, and the heat transfer and mass transfer direction is consistent, the material film surface can be maintained 30-70kg vaporization intensity of H20 (M2 h).
widely used in food, meat, yeast, starch, chemicals, dairy products and so on.
