Introduction of Straw Carbonization Machine
This line converts straw (corn stalk, wheat straw, rice straw, cotton stalk, etc.) into high-quality biochar through continuous high-temperature pyrolysis (380–850°C) under oxygen-limited conditions. Since straw is bulky, light and often moist, the line integrates crushing and drying pretreatment. The pyrolysis gas is purified and recycled for self-heating, while wood vinegar and wood tar are recovered as by-products.
Advantages of Straw Carbonization Machine
01
Dynamic Sealing
Specialized inlet and discharge designs keep the system sealed during operation; material enters continuously while finished charcoal is discharged, with a daily capacity of 20–120 tons.
02
Double-Layer Drum
The inner drum handles drying while the outer drum handles carbonization, cutting the footprint by nearly half and reducing heat loss.
03
Triple Safety Protection
Explosion-proof panels release abnormal pressure, sensors detect anomalies immediately, and IoT remote monitoring enables real-time management.

Working Principle of Straw Carbonization Machine
Process: Raw material storage → conveying → sealed feeding → continuous carbonization → syngas recovery & reuse → char cooling → finished product collection/packing.
Main equipment: Feeding hopper, screw conveyor, rotary carbonization furnace, dust removal & condensation system, water-cooled discharger, gas recycling unit, and centralized control cabinet.
Applications: Soil amendment / biochar fertilizer, metallurgical insulation, adsorbents, incense & filter materials, or briquetting into charcoal sticks.
