Product Description

Product introduction:
The hollow paddle dryer is a horizontal agitating dryer mainly based on heat conduction. Because the inner hollow mixing blade is shaped like a boat paddle, it is called a hollow paddle dryer. Since the heat required for the drying of the equipment is indirect heating by heat conduction, the drying process only needs a small amount of gas to take away the moisture, which greatly reduces the loss of this part of the heat taken away by the gas and improves the use of heat. Rate, hollow blade dryer is an energy-saving drying equipment. It is suitable for the drying of granular and powder materials, and can smoothly dry paste materials.

Working principle:
Wedge-shaped hollow blades are densely arranged on the hollow shaft, and the heat medium flows through the blades through the hollow shaft. The heat transfer area per unit volume is large, and the temperature of the heating medium ranges from -40°C to 320°C. It can be steam or liquid: such as hot water, heat transfer oil, etc.
Indirect conduction heating, no air is carried to take away the heat, and the heat is used to heat the material. The heat loss is only the heat dissipation to the environment through the insulation layer of the body.
The heat transfer surface of the wedge-shaped blade has a self-cleaning function. The relative movement of the material particles and the wedge-shaped surface produces a scrubbing effect, which can wash off the attached material on the wedge-shaped surface, so that a clean heat transfer surface is always maintained during operation. The shell of the blade dryer is Ω-shaped, and two to four hollow stirring shafts are generally arranged in the shell. The shell has a sealed end cover and an upper cover to prevent material dust from leaking out and give full play to its effect. 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 excellent heat transfer effect.
