Hollow blade stirring dryer is an indirect heating low-speed stirring dryer that can operate continuously and belongs to high-efficiency and energy-saving drying equipment. There are two or four hollow rotating shafts inside the equipment, and wedge-shaped hollow blades are densely arranged on the hollow shafts. The heat medium flows through the blades through the hollow shafts. The flow channel inside the hot shaft is special and cleverly designed. The two shafts rotate in opposite directions, causing compression and relaxation between the shafts. With the help of wedge-shaped blades, the material is constantly flipped and stirred, updating the heating surface of the material and greatly improving the evaporation efficiency. According to the drying temperature, commonly used heat media include steam, thermal oil, hot water, and cooling water, which can complete unit operations such as drying, cooling, heating, and reaction.
