Bio charcoal making machine is closely related to the processing of waste biomass and the production of biochar. Biomass carbonization machine is the core equipment for converting various waste biomass into biochar. It plays a vital role in environmental protection and resource utilization.
So what is biochar? Biochar is a carbonaceous material produced by the high-temperature pyrolysis of biomass under anoxic or anaerobic conditions. Its primary chemical composition includes carbon, hydrogen, oxygen, and nitrogen, with a high carbon content and a low ash content. Biochar has a rich pore structure and a high specific surface area. These properties make it crucial for a wide range of applications.
How the Bio Charcoal Making Machine Works
The bio charcoal making machine primarily utilizes continuous pyrolysis, with high-temperature anaerobic pyrolysis technology being its core secret. When biomass is fed into the biochar making machine, it first enters a sealed reaction vessel, which becomes the stage for its remarkable transformation.
A special oxygen-deficient or oxygen-free environment is created within the pyrolysis plant. This is a key condition for the successful anaerobic pyrolysis reaction. In the presence of oxygen, the biomass may burn, rather than undergoing the desired pyrolysis and conversion to biochar.
Next, the carbonization equipment rapidly heats up. The temperature is adjusted based on the type of biomass and the desired biochar properties.
Under the influence of high temperatures, the organic matter in the biomass begins to decompose. These organic matter, like tightly packed “molecular building blocks,” are gradually disassembled and reassembled under the impact of the high temperature. Water in the biomass is first evaporated.
Subsequently, volatile substances gradually evaporate as the temperature rises, leaving the biomass as gases. As the reaction continues, the remaining material undergoes further pyrolysis. During this process, the carbon in the biomass is gradually enriched and rearranged, forming biochar with a unique structure.
This unique structure gives biochar a rich porosity. This rich porosity is the key to its many excellent properties. For example, it significantly increases its surface area, enhancing its adsorption capacity. Biochar plays a vital role in absorbing nutrients from soil and pollutants from wastewater.
In addition to biochar, the biomass pyrolysis process also produces other byproducts, such as tar and syngas.
Wood tar is a black, viscous liquid. It contains a variety of complex organic components and has applications in the chemical industry. After purification, the syngas can be used as a heating device in the pyrolysis reactor.
