Drum dryer performance characteristics:
1, high thermal efficiency. Because the heat transfer mechanism of the drum dryer is heat conduction, the heat transfer direction is consistent throughout the entire operating cycle. Except for the cover heat dissipation and thermal radiation loss, all the remaining heat is used for evaporation of the moisture content of the cartridge membrane, and the thermal efficiency can reach 70%. -80%.
2, the operation flexibility, wide applicability. Adjust the drying factors of the drum dryer. Such as the concentration of the feed, the thickness of the coating material film, the temperature of the heating medium, the rotation speed of the drum, etc., can change the drying efficiency of the drum dryer, and many factors are not implicated in each other. This brings great convenience to the drum drying operation, so that it can adapt to the drying of a variety of materials and different production requirements.
3, drying time is short. The drying cycle of materials is generally only 10-300 seconds, suitable for heat-sensitive materials. If the drum dryer is set in a vacuum, it can be operated under reduced pressure.
4, drying rate. Since the coating material applied to the wall of the coating is very thin, generally 0.3-1.5mm, and the direction of heat transfer and mass transfer is consistent, the surface of the coating film can maintain 20-70kg? The strong evaporation drum dryer of H2O/m2?h is suitable for materials : Suitable for the drying of liquids or more viscous materials in the chemical, dye, pharmaceutical, food, metallurgical and other industries
Changzhou Changjiang Drying Dye Dedicated Drum Dryer
Recently, according to the customer's demand, the drying of the Yangtze River has focused on the drying characteristics of the dye industry, optimized the performance of the drum dryer, and introduced a drum dryer suitable for use in liquids or more viscous materials. The tumble dryer is an internal heating conduction type rotary continuous drying device. The rotating drum passes through the lower chute and adheres to a film of thickness. The heat is transported through the pipe to the inner wall of the drum and is conducted to the outer wall of the drum. The feed film is then conducted, so that the moisture in the film is evaporated, dehumidified, The moisture content of the material is dry. The dried material is scraped off the drum by a scraper on the surface of the drum to an auger placed under the scraper, and the dry material is collected and packaged by an auger.
