Kernel separator OLSA

cascadefor the food industrycompact

Overview
The Cascade separator OLSA from Bühler is a vertical cylindrical cascade aspirator designed for separating hulls from broken soybean kernels in warm and hot dehulling processes. It exposes product to controlled airflow across multiple stages to achieve high separating performance.

Key benefits

• Efficient separation - Repeated aspiration across five cascaded zones increases separating efficiency.
• Low maintenance requirements - No moving parts in the separation zone; integrated sight glasses and large access doors simplify inspection and adjustments.
• Energy efficiency - Option for a closed air circuit with air recirculation reduces heat loss and improves energy utilisation.

Highlight features

• Cascade aspiration — Cleaning and separation in five zones - Product falls through five cascaded separation zones and is repeatedly exposed to an airflow for high separating efficiency.
• Small footprint - Vertical cylindrical design provides a large separation surface while minimising installed floor area.
• Versatile models & options - Available in two model variants and multiple sizes; option of an aspiration box with air recycling (for warm/hot dehulling) or without an air recirculation hood for ambient‑temperature separation.

Applications

• Primary use: soybean warm and hot dehulling to separate hulls from broken soybean kernels after cracking.
• Also suitable for grain, oilseed and prepared products requiring aspiration‑based separation.

Operation & maintenance
The absence of moving parts in the separator ensures high operating safety and low maintenance. Sight glasses and large access doors provide straightforward inspection and process adjustment. The air recirculation option supports energy‑efficient operation in warm/hot processes.
