Performance characteristics

1. The structure of the three tube dryer adopts a sleeve type, which enables rapid drying of materials.

2. Design the cylinder to self insulate, achieving a thermal efficiency of over 80%.

3. The product has exquisite structure and smooth operation.

4. Good drying effect, with a coal consumption of less than 8kg per ton of dry material.

5. The fuel can be used with kerosene and gasoline. Capable of drying block and powder materials below 20mm.

6. Reduce the footprint by about 50% compared to a single drum dryer, lower the civil engineering investment by about 50%, and lower the electricity consumption by 60%.

7. The final moisture index can be easily adjusted according to user requirements.

8. Low exhaust temperature and long usage time of dust removal equipment.

9. No need for large or small gears to rotate, using a tugboat for rotation.

10. The discharge temperature is below 60 degrees. Can continuously produce packaging.

working principle

The material enters the inner layer of the three cylinder dryer through the feeding device. The material is continuously picked up and scattered under the inner layer's plate to achieve heat exchange in a spiral motion. The material moves to the other end of the inner layer and enters the middle layer for counter current drying. The material is repeatedly lifted in the middle layer, following a two-step forward and backward motion. The material fully absorbs the heat emitted by the inner layer drum and the middle layer drum in the middle layer, while also extending the drying time. The material reaches a dry state here. Then the material falls from the other end of the middle layer into the outer layer, and travels in a rectangular multi loop manner in the outer drum. The material that achieves the drying effect quickly travels out of the drum under the action of hot air, while the wet material that does not achieve the drying effect cannot move quickly due to its own weight. The material is fully dried in this rectangular plate, thus achieving the purpose of drying.
