High-capacity pre-cleaner drum for grain silo storage
Optimize your pre-cleaning process with a high-capacity drum that efficiently removes unwanted debris from cereals and powdery products, ensuring your downstream equipment operates at peak performance and reducing maintenance demands.

Removes Foreign Materials from Grains and Powders
The SEMB Pre-Cleaner Drum by Stolz efficiently addresses the challenges of cleaning grain and powdery products by utilizing a rotary drum sieve system. This equipment operates continuously, removing large foreign materials and fine dust to streamline subsequent processing stages. Ideal for industries like agribusiness and biofuel production, the SEMB is commonly employed in the processing of cereals, rice, cocoa, flour, and more. Its high-capacity operations ensure effective handling of incoming materials, reducing the frequency of dryer cleanings and minimizing equipment wear.
With an integrated suction system to enhance waste removal, the SEMB pre-cleaner supports seamless integration into your existing production line, protecting downstream equipment and optimizing cleaning efficiency. It features a feeding shovel with adjustable slope and a double-part waste hopper, providing flexibility in processing varying product types and conditions.
Manufactured with robust components, the SEMB Pre-Cleaner Drum can be customized to meet specific operational needs, including variable sieve mesh sizes and additional options such as anti-filling sensors and reclaiming hoppers. This adaptability ensures it meets diverse industrial requirements and maintains efficient, continuous operation.
