3. Stone Removing
The destoner removes stones and heavy impurities according to density difference, protecting downstream equipment.

4. Magnetic Separation
The magnetic separator removes metal impurities to ensure safe operation.

5. Gravity Separation
The gravity separator separates beans according to specific gravity and improves uniformity and quality.

6. Color Sorting
The color sorter detects and removes discolored, damaged and defective coffee beans through advanced optical technology.

7. Polishing (Optional)
The coffee polisher removes surface dust and improves bean appearance and market value.
