Overview scraper dryer is heating conduction type of rotating drying equipment, wet material in the drum outer heat transfer by conduction mode, the removal of water, to water it requires moisture content, heat to the outer wall of an inner cylinder tube wall and then through the membrane material, high thermal efficiency, continuous operation, it is widely used in liquid or dry material strip material for paste and viscous materials more appropriate. Structure can be divided into two kinds of forms: monocular, binoculars dryer, it is also divided according to operating pressure atmospheric and vacuum forms. Features and application: 1. operating flexibility, adaptability, able to adapt to a variety of materials and different production requirements 2. high thermal efficiency, which is typically between 80-90% thermal efficiency of about 3. The drying time is short: the outer wall of the drum on dry material drying wet material film can be formed at the beginning is generally 0.5-1.5mm, the whole drying cycle is only 10-15s, especially suitable for heat sensitive materials The drying rate: As thin film material, and heat and mass transfer in the same direction, the material surface of the film may remain 30-70kg.H2O (m2.h) vaporization strength is widely used: rice, cereals, α starch, potato powder, dried foods refined into a sheet, powder and granular form.
