BST-50S Sawdust Charcoal Machine: Large Capacity & Reliable Output

Stable Recycling Efficiency

BST-50S sawdust charcoal machine features a self-cleaning system for tar/wood vinegar/dust. It enables continuous operation of up to 7,200 hours per year. This reliability brings multiple benefits for wood processing industry:

Consistent Charcoal Production
Stable sawdust charcoal output, provides a reliable supply whether for on-site boilers or for sale to downstream customers. Generally, it ensures continuous flow of in-stock product.
Lower Operating Costs
Continuous operation reduces downtime enery cost, maintenance fees, and labor requirements. Thus, it maintains smooth production while lowering overall operational expenses.

Large Processing Scale

BST-50S wood to charcoal machine features a dual-tube main furnace design, ensuring a processing capacity of over 10 m³ per hour. This high throughput brings multiple operational benefits for the wood processing industry:

Significant Space Savings
By converting loose sawdust (≈0.25 t/m³) into compact charcoal (≈0.7 t/m³), BST-50S can reduce peak storage space by nearly 90%, freeing up valuable factory area and improving site safety.
Reduced Disposal & Transport Costs
With high processing capacity, BST-50S can convert daily sawdust into charcoal on-site, minimizing the need for external hauling or landfill disposal. It lowers transportation and tipping expenses.

Successful Case: Sawdust Charcoal Making Machine in Brazil

01 Client Background

In August 2025, Beston Group delivered a BST-50 sawdust charcoal making machine to a bioenergy company in Brazil. The client, originally working with eucalyptus & bamboo sawdust from the local wood-processing sector, supplies clean fuels to the domestic market.

02 Problems Faced

The client previously relied on traditional earth kilns. This caused low output, unstable quality, and high labor demand. The kilns making it impossible to keep up with Brazil’s rising demand for barbecue charcoal. For large-scale sawdust processing, this meant wasted resources and limited ability to scale up.

03 Solution

We provided BST-50 biomass pyrolysis plant with a drying system to handle large volumes of eucalyptus & bamboo sawdust. The system provides a high degree of automation and stable operation. This allows Brazilian client to realize a high-value application of sawdust.

04 Value Added

Stable Output: Delivers 6,000 tons of barbecue charcoal annually with consistent quality.
Lower Costs: Automation reduces manual labor and operating expenses.
Market Advantage: Strengthens competitiveness in the barbecue charcoal sector while supporting sustainable growth.

Working Processing

01 Sawdust Pretreatment

Drying: Moisture is reduced to below 20% to improve pyrolysis efficiency.
Screening: Proper size ensures smooth feeding and stable operation.

02 Sawdust Pyrolysis

After entering biochar reactor through the high-angle belt conveyor, the sawdust undergoes the following changes:

Moisture Removal: Rising temperature drives out water from sawdust.
Gas Release: At 200–500℃, volatile gases are released. These gases serve as heating fuel for the reactor.
Charcoal Formation: Above 500℃, sawdust turns into stable charcoal.

03 Combustible Gas Recycling

The combustible gas, after dust removal, is sent into the burner. It supplies continuous heat for the reactor and reduces external fuel demand.

04 Flue Gas Utilization

Direct Treatment: A part goes to the tail gas system after cyclone dust removal.
Heat Exchange: A part enters the air-to-air exchanger to preheat combustion air.
Drying Support: Another part heats the dryer to support sawdust drying.

05 Sawdust Charcoal Discharge

The finished sawdust charcoal is cooled by multi-stage water-cooled screws before being safely discharged and collected.

06 Tail Gas Treatment

The remaining gas passes through heat exchanger, bag filter, desulfurization tower, and activated carbon unit, then is released through the chimney.
