Sunflower Seed Processing Line

Sunflower Seed Processing Line

Sunflower seeds are not only processed for oil extraction but are also sold as snack foods and bird feed, making it necessary to have a processing line capable of handling various end-product standards. Shijiazhuang Xinlu Technology Co., Ltd. has developed a Sunflower Seed Processing Line that offers adaptability, efficiency, and stable output for small, medium, and large-scale processing operations.

The processing starts with bulk material intake and feeding into a pre-cleaning unit. This machine uses screens and aspirators to remove coarse contaminants such as soil, branches, and husks. Since sunflower seeds are relatively light and prone to breaking, the equipment is calibrated to reduce mechanical stress during material transfer.

A critical part of the sunflower seed processing line is the dehuller, which removes the hard shell from the seed without damaging the kernel. The machine adjusts pressure and rotational speed according to the seed size and variety. After hulling, a separation unit distinguishes the kernel from the shell, using air and sieves to make the process efficient.

Post-dehulling, the kernels are subjected to gravity separation, which removes broken kernels, undersized material, and foreign matter. For snack-grade sunflower seeds, a polishing machine can be added to improve seed appearance. An optional grading machine can classify seeds into uniform sizes, which is essential for packaging and marketing.

The control system enables operators to manage the entire line from a central panel, adjusting flow rates, separating thresholds, and monitoring key indicators such as temperature and capacity. All parts in contact with the seeds are made from food-grade materials to ensure compliance with hygiene standards.

Shijiazhuang Xinlu Technology Co., Ltd. supports customers with layout design, installation guidance, and technical support to ensure the sunflower seed processing line performs efficiently throughout its life cycle. This solution is ideal for seed producers looking to enhance product quality for human consumption, oil pressing, or feed purposes.
