Briquetting Process

The briquetting procedure is the conversion of agricultural waste into uniformly shaped briquettes that is easy to use, transport and store.

The briquetting process primarily involves drying, grinding, sieving, compacting, and cooling. The components of a typical briquetting unit are (1) preprocessing equipment; (2) material handling equipment; and (3) briquetting press.

The idea of briquetting is using raw materials that are not usable due to a lack of density, compressing them into a solid fuel of a convenient shape that can be burned like wood or charcoal. The briquettes have improved physical and combustion characteristics than the initial waste.

We are using our state-of-the-art briquetting machine to make charcoal. We also keep trying to improve our charcoal making process in order to meet customer satisfaction.

Pyrolysis Process

We apply the pyrolysis process to guarantee the purity of the biochar product.

Pyrolysis is a thermochemical decomposition process of organic material without or with limited air at a temperature of around 300-500°C for 4 to 7 hours so that it is enough to deconstruct the biopolymers contained in the raw materials.

Because there is no oxygen, combustion does not occur, but the biomass decomposes thermally into gas (fuel gas), liquid (bio-oil), and solid (charcoal). The proportion of the product yield adjusts the composition of raw materials and process parameters.

Through the pyrolysis method, we guarantee the production of superior quality and safe biochar for you.

GO

Stage 1: Material Mixture

We only use fine and medium grain hardwood sawdust, clean and high quality sawdust.
Then we mix the hardwood sawdust using best composition, according to our standards, or based on customer’s requirements.

Stage 2: Drying

The mixed sawdust is then dried at the optimal temperature, to condition the material ready for extrusion.

Stage 3: High Temperature Extrusion

The sawdust material is then extruded at an optimal high temperature. Being a quality briquette, it has 4800 kcal/kg heating value.

Stage 4: Sawdust Briquette

Briquettes are selected through a QC process and are ready to be carbonized.

Stage 5: Carbonization (Pyrolysis)

The next process is to burn the briquettes in a special furnace, using the low oxygen pyrolysis method.

Stage 6: Ready To Grill

After the pyrolysis process is complete, the charcoal briquette products with high carbon and calories are ready to be packaged and shipped to customers.
