Piles of sawdust are often a headache in wood processing plants. If the sawdust has high humidity it will easily lead to mouldy lumps. This doubles the transport costs. If the waste sawdust is burned directly, it will cause a waste of resources. If you use a sawdust dryer machine to dry the sawdust. After drying the sawdust price doubled. It can be made into mechanism charcoal or biomass pellets.
Sawdust dryer turns sawdust with 30% moisture content into fluffy sawdust with 8% moisture content in a very short time. Unique hot air through-flow design avoids carbonisation. Meanwhile, it is equipped with dust explosion-proof system to ensure safety. Only energy consumption can be controlled to save 15% of the cost. Thus turning waste into treasure.

Its core principle is to reduce the moisture content of sawdust by heat exchange and air circulation. When the dryer is working, the wet sawdust is sent to the drying cylinder through the conveying device. The cylinder is equipped with heating devices, such as electric heaters, gas heaters, burners, steam heat exchangers and so on. The hot air can fully contact with the sawdust. Moisture is then evaporated by the heated airflow. The moisture generated during the drying process is discharged by the moisture removal system. The final dried sawdust is collected by discharging device. The sawdust dryer is designed with multi-layer drum or vibrating screen. This prolongs the residence time of sawdust. Improve the uniformity of material drying. The whole set of dryer includes: air heater, feeder, airflow drying tube, cyclone separator, fan and other components. Through these parts work together. Make the whole drying process efficient and orderly.
According to the difference of heat source and equipment structure. Common sawdust dryer machinecan be divided into the following types:
Drum dryer: through the rotating drum to make the sawdust constantly tumbling. Sawdust and hot air contact evenly. Drum dryer is suitable for large-scale continuous production.
Airflow dryer: Using high-speed airflow to transport the sawdust suspension and rapid drying. High drying efficiency but high energy consumption.
Box dryer: adopts static layered drying. Suitable for small-scale processing. Convenient operation but long drying cycle.
Solar dryer: rely on solar energy auxiliary heating, energy saving and environmental protection. But limited by weather conditions.
Sawdust briquette machine is a kind of screw extrusion type press. Also known as: biomass ball making machine and charcoal machine. It is used to make biomass raw material into fuel-type balls. Sawdust briquette machine can take waste agricultural materi
Charcoal briquette extruder machine is also called coal stick extruder. Adopting the principle of spiral extrusion. It is a coal bar forming equipment that compresses the modulated coal powder into a prefabricated shape with a certain strength.
Bamboo charcoal has high utilisation value. In daily life, bamboo charcoal is mainly used to eliminate and adsorb odours. For example, it can be used to eliminate the odour of a new car or to eliminate the odour of a new house after renovation.
Continuous carbonization furnace can directly carbonise: sawdust, coconut shell, rice husk, bamboo shavings, straw, nut shell, coffee shell, palm shell, peanut shell, and other biomass raw materials. It is a new type of carbonization equipment.
Horizontal Carbonization Furnace Also known as charcoal making machine. It can carbonise all kinds of raw materials. The equipment adopts new high temperature dry distillation pyrolysis carbonization technology.
The vertical lifting carbonization furnace uses advanced airflow carbonization. It can produce all kinds of biomass charcoal. The carbonization furnace has convenient operation, environmental protection and energy saving, high production efficiency, and c
Sawdust dryer refers to putting the powder granular wet sawdust. After a high temperature, hot airflow is conveyed and dispersed. Make the moisture in the material evaporate. Sawdust dryer can dry sawdust, rice husk, wood chips, biomass granules...
The air flow dryer is widely used for drying powder-like material. The humidity can be controlled at 10-16%. It is a kind of highly efficient, continuous, and fast solid fluidised drying method. Loose powdery or granular materials are dispersed and suspen
