Hollow Paddle Dryer

1. Low energy consumption: Thanks to indirect heating, no large volume of carrier air takes away heat, and the outer wall of the dryer is equipped with an insulation layer. For high-humidity materials.
2. Low system cost: The huge heat transfer surface per unit effective volume shortens the processing time and reduces the equipment size, thus greatly saving the building area and space.
3. Wide range of processable materials: Different media can be used to process both heat-sensitive and high-temperature treatable materials. Common media include: saturated steam, thermal oil, hot water, cooling water, etc. It can be operated continuously or intermittently and applied in many fields.
4. Low environmental pollution: A small amount of carrier air results in minimal entrainment of dust materials. For working conditions involving polluting materials or solvent recovery, a closed circulation system can be adopted.
5. Low operating cost: The equipment only requires 1 operator per day for normal operation. Low-speed stirring and a rational structure lead to minimal wear and very low maintenance costs.
6. Stable operation: Due to the special compression-expansion stirring effect of the wedge-shaped paddles, material particles are in full contact with the heat transfer surface. In the axial range, the temperature, humidity, and mixing temperature gradients of materials are extremely small, thus ensuring process stability
