Soybean dehulling separator
Enhance the quality of your oilseeds and grains by efficiently separating hulls and impurities, utilizing advanced cascade technology for optimal product purity and yield in continuous operations.

Separates and Dehulls Soybeans and Oilseeds Efficiently
The Cascade Separator OLSA by Bühler stands out as a vital component in soybean and oilseed processing operations. Utilizing a cascade aspiration process, it effectively achieves efficient separation and dehulling through five aspirated zones. Designed for continuous and high-speed operations, it optimizes production for a wide range of end products including soybean meal, wheat and chickpea flours, and vegetable oils. Its compact vertical design integrates seamlessly into existing production lines, while its closed air circuit enhances energy efficiency by minimizing heat loss. The machinery’s absence of moving parts reduces maintenance requirements, supported by ease of access for adjustments via large doors. Available in various models to match specific process conditions, it ensures versatility and adaptability for food and feed processors. With support for customization and Bühler’s engineering expertise, the separator promises high operational safety and consistent performance.
