Impact dehuller for sunflower, soybean, and cottonseed
Enhance oil extraction efficiency with a dehulling solution that gently separates hulls while maintaining high-protein meal quality, ideal for diverse seed processing operations.

Efficiently Dehulls and Separates Oilseeds
The Impact Dehuller DOSB from Bühler Group is engineered for oilseed processing, delivering optimized performance for dehulling sunflower seeds, soybeans, and cottonseeds. This vertical dehuller utilizes an adjustable impact cone to facilitate efficient separation of hulls without damaging kernels, ensuring low-fiber, high-protein meal production. With a throughput of up to 180 tons per day, the DOSB offers seamless integration into high-speed, continuous operations with minimal downtime, thanks to its wear-resistant steel lining and easy-access design for maintenance. Fitted with an advanced, permanent magnet system, it enhances machine protection by removing ferrous contaminants, which prolongs equipment life and ensures product purity. Ideal for processing multiple seed varieties, the DOSB supports flexible production capabilities crucial for edible oil manufacturers and seed processing plants.
