The Continuous Azolla Biochar Machine is equipment that carbonizes Azolla under high temperature conditions in a carbonization machine.

By carbonizing Azolla feedstock with the biochar machine, biochar with high fixed carbon content and a low H/Corg ratio is obtained. This biochar can be used for carbon credit applications and mixed with animal manure, such as cow dung, to produce biochar-based fertilizer pellets, generating two sources of income.

Carbonization

Raw material

Carbonization equipment which can carbonize coconut shell, walnut shell, apricot shell, hemp pole, sawdust, sawdust, rice husk, bamboo, eucalyptus, mushroom residue, medicine residue, furfural residue, coffee residue, palm shell, peanut shell and sunflower seed shell in the carbonization machine under high temperature conditions.

Crushed

Raw materials are heated in a carbonization furnace under oxygen‑limited conditions. The organic matter undergoes pyrolysis, removing volatile components, and finally forming solid biomass charcoal. The carbonization temperature and holding time directly affect the quality of finished charcoal.

Drying

The charcoal powder is mixed with an appropriate amount of binder, and extruded by a briquette machine under high pressure to form regular charcoal sticks or charcoal blocks. The density and molding rate of the finished product can be controlled by adjusting the pressure and feeding speed.

Carbonization

Raw materials with high moisture content need to be dried first. The drying system removes free water in the material to ensure that the moisture is controlled within 8‑12%, which avoids cracking and poor molding during subsequent carbonization and briquetting processing.

Azolla carbonization machine is a device that heats and azolla or other biomass materials under oxygen-free conditions to produce biochar, combustible gas, etc.

The Azolla Biochar Machine consists of equipment such as a conveyor, main drum, dust removal system, purification system, burner, and distribution cabinet. It adopts an upper-lower layer design, significantly improving drying and carbonization efficiency. This newly developed continuous carbonization equipment integrates high efficiency, environmental protection, and intelligence.

The high-quality Azolla biochar produced has a high fixed carbon content and an H/Corg ratio of <0.2, meeting the highest quality standards of Puro Earth.

The entire production line can also be equipped with a mixer, pellet machine, and pellet drying machine, allowing the produced biochar-based organic fertilizer pellets to be directly packaged and sold.

01 Screw Conveyor

The screw conveyor is used for sealed and continuous feeding of raw materials into the carbonization system. It ensures stable material transfer while preventing air leakage during operation.

02 Carbonization Machine

The carbonization machine is the core unit of the system, where organic materials are thermally decomposed under controlled conditions. Through continuous heating, volatile components are released and converted into combustible gas, producing high‑quality charcoal.

03 Cyclone

The cyclone separates solid particles from the hot gas generated during carbonization. It removes coarse charcoal powder, protecting downstream equipment and improving system stability.

04 Charcoal Powder Cooler

The charcoal powder cooler reduces the temperature of collected charcoal powder. Controlled cooling prevents spontaneous combustion and facilitates safe handling and storage.

05 Washing Tower

The washing tower is used to clean carbonization gas by removing dust and tar components. It improves gas quality and reduces pollutant emissions.

06 Condensing Tower

The condensing tower cools the carbonization gas to condense tar and moisture. This step enables effective recovery of by‑products and further gas purification.

07 Circulating Cooling Pool

The circulating cooling pool supplies cooling water for the washing and condensing systems. It enables closed‑loop water circulation, reducing water consumption and supporting continuous operation.
