Dry Milling Cambodian Green Coffee: What Buyers Should Know

Dry milling is where Robusta Cambodia parchment or dried cherry becomes export-ready green coffee. The quality of this stage affects physical consistency, defect removal and the reliability of the final shipment.

Preparation should match the contract

Hulling, cleaning, size separation, density separation and sorting may all be used depending on the lot. Buyers should define the required preparation rather than assuming every export grade is processed the same way.

Sorting adds value only when calibrated

Color sorting, hand sorting and density separation can remove unwanted material, but machines and teams need clear acceptance criteria. Excessive sorting can also add cost without improving the buyer's real application.

Prevent lot mixing

The mill should maintain lot identification throughout intake, processing, temporary storage and bagging. This is especially important for differentiated Robusta Cambodia lots sold on traceability.

Mill questions

• What equipment is used?
• How is the mill cleaned between lots?
• How are rejects handled?
• How is final weight reconciled?
• Is a post-mill sample checked before bagging?

Dry milling is the final opportunity to improve physical preparation before export. A strong system protects both quality and traceability.
