Key benefits

Efficient separation

The cascade separator exposes your product to air flow in multiple separation zones, bringing you excellent separating efficiency.

Low maintenance requirements

Without any moving machine parts, the cascade separator offers high operating safety and low maintenance requirements. Furthermore, integrated sight glasses and large doors are fitted for easy access and process adjustments.

Energy efficiency

The closed air circuit prevents heat loss, thereby significantly increasing energy efficiency.

Highlight features

Cascade aspiration

Cleaning and separation in five zones

Your grain, oilseed or prepared products fall through a total of five cascaded separation zones, where they are exposed to an airflow. This repeated aspiration results in a high degree of separating efficiency.

Small footprint

Easy to fit into your plant

The vertical cylindrical form creates a high surface area for separation with only little space requirements.


A choice of models to meet your needs

The cascade separator comes in two models and different sizes. You can choose the aspiration box option with air recycling, perfect for the warm and hot dehulling of soybeans. For other separating processes at ambient air temperatures, the unit can be specified without an air recirculation hood.
