Triple Pass Dryer Features
- The investment required for equipment is 1/6 of the imported products.
- The thermal efficiency of the self-insulation of the cylinder is as high as more than 70% (the thermal efficiency of the traditional single-cylinder dryer is only 35%), and the thermal efficiency is improved by more than 50%.
- Compared with the single-cylinder dryer, the floor area is reduced by about 50%, the civil construction investment is reduced by about 50%, and the power consumption is reduced by 60%.
- A variety of circumferential lifting materials are combined and distributed, which can effectively control the drying time and achieve good drying effect.
- The desired final moisture index can be easily adjusted according to user requirements
- Using frequency conversion speed regulation to control material flow.
- The outlet air temperature is low, the dust removal equipment is used for a long time, and the next process can be continuously produced.

Working Principle
The triple-pass dryer is composed of three layers of inner and outer cylinders.
The wet material enters from one end of the inner cylinder. Inside the dryer, the inner cylinder goes from the inner cylinder to the middle cylinder, and after drying from the middle cylinder to the outer cylinder, the dry material enters from the outer cylinder.
The tail was collected with a separator. The hot air enters from the inner cylinder and is discharged from the tail of the outer cylinder. The barrel is equipped with a forward copying plate, so that the material is continuously picked up and sprinkled during the rotation of the barrel, so that it is fully contacted with the hot air flow, so as to improve the drying efficiency and make the material achieve the drying effect.
The advantages of two and Triple-pass Dryer: Materials suitable for drying: wood chips, bamboo chips, mushroom residues, coffee grounds, vinegar grains, distiller’s grains, eucalyptus residues, straw crushed materials, etc.
CUSTOMER CASES
Triple-Pass Dryer, Energy Saving And More Efficient
- The required investment of the equipment is 1/6 of the imported products other countries.
- The self-heating thermal efficiency of the dryer body is as high as 70% (the thermal efficiency of the traditional single drum dryer is only 35%), and the heat efficiency is increased by more than 50%.
- Compared with the single drum dryer, it will reduce the land occupation by about 50%; the civil construction investment will be reduced by about 50%; the electricity consumption will be reduced by 60%.
- Combination of Multi-directional lifting, which can regulate of drying time effectively and get good drying effect.
