Tumble dryer

Equipment principle

Three-cylinder dryer:

The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the lifting plate in the inner layer to achieve heat exchange in a spiral manner. The material moves to the other end of the inner layer and enters In the middle layer, countercurrent drying is carried out. The material is repeatedly pushed forward in the middle layer in a two-step-forward and one-step-back motion. The material in the middle layer fully absorbs the heat emitted by the inner drum and the heat of the middle drum. At the same time, the drying time is extended. The material reaches the best drying state here.

The material travels to the other end of the middle layer and falls into the outer layer. The material travels in a rectangular multi-circuit manner in the outer drum. The material that has achieved the drying effect travels quickly and is discharged from the drum under the action of hot air. The wet material that has not achieved the drying effect cannot travel quickly due to its own weight. The material is fully dried in this rectangular lifting plate, thereby completing the drying purpose.

Preface.

Single-cylinder dryer

Tumble dryer is a drum dryer in which hot air flows in from the front and the hot air goes to the rear of the dryer. , fully contact with the material, and make full use of the heat transfer through heat conduction, convection, and radiation;

The heat energy is directly transferred to the material, so that the moisture of the material is continuously evaporated in the cylinder. The air induction device at the material inlet draws out a large amount of water and wet air flow to prevent secondary pollution caused by dust discharge; through internal spiral stirring, sweeping, and plate lifting, the movement of the material is promoted to complete the entire drying process;

Countercurrent conduction dehumidification avoids the need to reduce repeated drying procedures.

Product features:

Three-cylinder dryer

1. Three-cylinder design, high thermal efficiency utilization and large production capacity.

2. Three-cylinder structure, occupying less area.

3. Suitable for large-scale drying production lines such as sawdust and powder materials.

Single-cylinder dryer

The lifting plate in the cylinder is designed at multiple angles to make the material form a material curtain in the cylinder.

The contact surface between the material and hot air is high, the thermal efficiency is high, and the drying effect is good.

The structure is reasonably designed and easy to maintain. It has a wide range of materials and can be used for drying powder, wood chips, filamentous materials, etc.

1.2×12 meters, 1.5×12 meters, 1.5×18 meters are driven by sprockets and chains;

1.8×18 meters, 2.0*18 meters, 2×24 meters, 2.2*18 meters, 2.2×24 meters, 2.5*18 meters, 2.5×24 meters and other dryer models above are driven by gears.
