WORKING PRINCIPLE


Wedge shaped hollow blades are densely arranged on the hollow shaft, and the thermal medium flows through the blades through the hollow shaft. The heat transfer area per unit effective volume is very large, and the temperature of heat medium ranges from - 40℃to 320℃. It can be steam or liquid, such as hot water, heat transfer oil, etc. Indirect conduction heating, without air to take away heat, heat is used to heat materials. The heat loss is only the outward heat dissipation through the insulation layer of the body. The heat transfer surface of wedge blade has self-cleaning function. The relative movement of the material particles and the wedge-shaped surface produces a scrubbing effect, which can wash away the attached materials on the wedge-shaped surface and keep a clean heat transfer surface during operation. The shell of paddle dryer isΩtype, and two to four hollow mixing shafts are generally arranged in the shell. The shell is provided with a sealed end cover and an upper cover to prevent the leakage of material dust and give full play to the function.

 

The heat transfer medium flows through the shell jacket and the hollow stirring shaft through the rotary joint. The hollow stirring shaft has different internal structures according to the type of heat medium to ensure the heat transfer effect.
