Dingli dregs dryer has simple structure, mature technology, high production efficiency, easy operation and maintenance, stable operation of equipment during work, high temperature and rapid drying process, large heat transfer coefficient, high thermal efficiency, and high dry strength; high-speed mixing and drying The combination of airflow drying can fully disperse the viscous dregs and greatly increase the contact area between the dregs and the heat medium, which is beneficial to the drying process. A special scraping device is used in the machine to avoid sticking to the dregs.
