Sunflower husk pellets are a type of biomass fuel made from the by-products of sunflower seed processing. After the seeds are extracted for oil production, the remaining husks are compressed into small, cylindrical pellets. These pellets are highly efficient, with a high calorific value, making them an excellent source of renewable energy.

Key Characteristics:

High Calorific Value: Sunflower husk pellets have a high energy content, making them efficient for heating and power generation.
Low Moisture Content: The pellets are dried during production, ensuring they burn efficiently.
Eco-Friendly: As a by-product of sunflower processing, they contribute to waste reduction and sustainable energy production.

3. Production Process of Sunflower Husk Pellets

Caption: A typical production line for sunflower husk pellets.

The production of sunflower husk pellets involves several steps:

Collection of Husks: After sunflower seeds are processed for oil, the husks are collected.
Drying: The husks are dried to reduce moisture content, which is crucial for efficient combustion.
Grinding: The dried husks are ground into a fine powder.
Pelletizing: The powdered husks are compressed into pellets using a pellet mill.
Cooling and Packaging: The pellets are cooled and then packaged for distribution.

Quality Control:

Moisture Content: Must be below 10% for optimal combustion.
Pellet Density: High density ensures longer burn times and higher energy output.
Ash Content: Low ash content is preferred to reduce residue after burning.
