OLT-S Carbonization Machine -The First Choice For Biochar Production Equipment

January 22, 2024

Olten® OLT-S Carbonization Machine is the main biochar production equipment. It can process various biomass raw materials to obtain biochar. In recent years, with the development of environmental protection, the market demand for biochar is increasing. As a leading manufacturer of biochar production equipment in China, Olten® OLT-S Carbonization Machine must be your best choice.

Henan Olten Environmental Sci-Tech Co., Ltd.

Biochar Production Technology

During the high temperature carbonization process, the biomass is carbonized into bio-charcoal in a micro-oxygen environment. Except for biochar, there are also byproducts like combustible gas, wood vinegar and tar generated in the process. Owing to the differences between the raw materials, the biochar will be different. Generally, our biochar production units can process wood, rice husk, coconut shells, sawdust, straw, bamboo, palm kernel shells and sewage sludge, etc. But theoretically, it can process all the organic wastes.

Biochar Production Process

1.Dry: If the moisture content exceeds 15%, it is recommended to first dry it with a dryer to ensure the effect of carbonization in the next stage.

2.Carbonized: Biomass will be carbonized and pyrolyzed in a carbonization furnace to obtain biochar.

3.The combustible gas produced during biochar production goes to the condenser, which is then separated into wood vinegar and tar. After the flue gas is treated by the purification system, it is safely discharged outdoors.
