RC DE30 Destoner — Pneumatic Density Coffee Destoner (DE30 / DE60 / DE120 Series)
DE separates stones and heavy impurities from roasted coffee. Controlled airflow separates coffee beans from heavier particles, protecting final product quality and preventing stones, metal fragments and other impurities from reaching packaging or grinding.

Frequently Asked Questions
How does the DE Series separate stones from roasted coffee?
It uses fluid-dynamics airflow and weight differential: roasted coffee beans are light enough to be vacuumed upward into the storage tank, while heavy stones and metals fall into the collection drawer.
