Biochar Dryer
The biochar drying process utilizes controlled heat and airflow to evaporate moisture from the material. In a rotary biochar dryer, the biochar is fed into a rotating drum, where it is exposed to hot air generated by a heating system. The tumbling action ensures even drying, while exhaust systems remove humid air. This method guarantees efficient moisture removal without compromising the biochar’s structural integrity.
The coal rotary dryer operates by feeding wet coal into a rotating drum, which is slightly inclined. Hot air or combustion gases flow through the drum, either in the same direction (co-current) or opposite direction (counter-current) to the coal. As the drum rotates, the coal is lifted by internal fins and cascaded down through the hot air, ensuring even and efficient drying. The dried coal is then discharged from the other end.
