Product Introduction
Palm dregs is the residue left after the palm fruit bunches are shredded. After drying and granulation, it is a good biomass fuel. The palm residue tumble dryer is a dryer designed and manufactured by the company through a large number of experiments and according to the characteristics of palm residue materials and customer requirements. The company’s technical staff can, according to the characteristics of various biomass materials, output size, application requirements, cost control, degree of automation,

Optimize the drying process technology and equipment configuration on site working conditions and customer needs to meet the individual needs of customers.
working principle
The material flow is: the crushed material with a moisture content of about 25-55% is sent by the conveyor to the drum to achieve downstream drying. The material is continuously picked up and scattered under the inner layer of the copy plate, and moves forward in a spiral manner. Three layers, to realize the heat exchange between the material and the hot air, the material that achieves the drying effect is quickly discharged out of the drum under the action of the wind, and the wet material that does not achieve the drying effect is caused by

The material is too heavy to move quickly, and the material is fully dried in the control stroke to achieve the drying effect. The moisture of the material is reduced to 5-15% (discharge moisture is adjustable), and the drying process is completed and discharged by the screw conveyor. A self-cleaning device is installed inside the drum to prevent the material from adhering to the wall of the drum.
  The palm waste enters the dryer through the feeder. Due to the high temperature and hot air, the material heats up and reaches the wet bulb temperature of the hot air. At this time, the moisture of the palm waste hardly changes, and the temperature of the hot air decreases slightly. The heat released is mainly used for Preheating of palm waste.
BC section: constant speed drying section
　　The drying rate is a constant value, and there is always surface water on the surface of the palm waste in this section, and the heat transferred from the hot air to the palm waste is used for water vaporization. Therefore, the surface temperature of the palm waste is always kept as the wet bulb temperature of the air, and the hot air temperature and the moisture of the palm waste are rapidly reduced.
CD section: drying enters the deceleration section
　　The internal water diffusion rate of the palm waste is less than the surface moisture vaporization rate, and the surface of the palm waste does not have enough water, so the drying rate is reduced. The heat transferred from the air to the material is greater than the heat consumed by water vaporization, so the surface temperature of the palm waste continues to increase, and the air temperature further decreases.
DE section: enter the cooling section
　　The moisture content of the palm waste has dropped to the required value. The palm waste discharged from the dryer enters the cooling system to lower the temperature of the dried palm waste and prevent the palm waste from re-absorbing moisture in the air. The cooled palm waste can be directly pressed into blocks.
