Agricultural cleaner-separator for grain processing
Optimize your grain processing with a versatile cleaner-separator engineered to enhance purity by efficiently removing impurities, ensuring high-quality end products such as flour and oil. This essential integration streamlines the critical grain cleaning stage, boosting production line performance.

Screens, Cleans, and Grades Grains and Seeds
The Cleaner-Separator SNST from Stolz is an effective and efficient solution designed for agribusiness operators, grain storage facilities, and biofuel producers. It employs a combination of screening, cleaning, and grading technologies to handle diverse materials such as cereals, flours, cocoa, rice, and oilseeds. Central to its operation is a weighted rubber ball system that enhances screening performance by maintaining clean working surfaces, while a counter-current airflow removes light impurities like shells and hollow grains.
The SNST operates continuously, featuring a suspended casing with circular movement for increased efficiency, and offers variable motor power ranging from 0.75 to 7.5 kW. It integrates seamlessly into existing lines with options like a rotary feeder with air dust aspiration for uniform distribution and initial vacuum cleaning. Typical applications include the processing of cornflakes, granola, rapeseed oil, and ethanol, supporting throughput requirements typical of large industrial operations. Constructed from modern materials for durability and low maintenance, the SNST ensures reliability in demanding environments.
