Biomass Feedstock: The first step in the pelletisation process is the preparation of feedstock (Raw materials, like agricultural residues, wood shavings, etc.), which includes selecting a feedstock suitable for this process, its filtration, storage and protection. Filtration is done to remove unwanted materials like stones, metals, etc.

Drying: Next step is Drying; the moisture content of the raw material must be around 10% to 12 %—a rotary drum dryer equipment used for this purpose. Drying is the most energy-intensive process. However, this increases the efficiency of biomass, and it produces almost no smoke on combustion.

Grinding: Before feeding biomass to pellet mills for further processing, the biomass is reduced to small particles of the order of not more than 5mm. If the pellet size is too large or too small, it affects the quality of the pellet and, in turn, increases the energy consumption. Therefore, we ensure the particles are of a suitable size and consistent quality.

Pelletising: Once the raw material has achieved the moisture and size requirements, pellets are produced. The pellet mill machine is used to pelletise the raw materials into wood pellets.

Cooling: Pelletisation generates additional heat to reduce the heat before packaging coolers are placed at the end of the process. These coolers utilise the surrounding air to lower the temperature of the pellet, resulting in a pellet be 5 to 10 degrees C above temperature.

Final Sifting and Packaging: Lastly, the Pellets pass through a sifter to get rid of any dust or crumbs, which get recirculated back in the process. Once this is done, the pellets are ready to pack for distribution.
