Yes. WESORT offers an AI coffee cherry sorting solution for processors who need to control ripeness variation before pulping, fermentation or further processing. The solution is built around the customer’s actual cherries, quality standard and production conditions.
The problem starts when one harvest contains several maturity levels
Coffee cherries rarely arrive in a perfectly uniform condition. During the harvest season, green cherries, properly ripe cherries and overripe cherries can enter the same receiving line. To a busy processing plant, this may look like a normal raw-material variation. In the next stage, however, the difference in maturity can create an inconsistent feed and make the process harder to control.
Many processors first try to manage this variation with manual inspection. Operators stand beside the line and remove cherries that look too green, too dark or visibly abnormal. This approach may work for small batches, but it becomes difficult to maintain the same judgment throughout a long shift. Borderline cherries are particularly challenging because different people may classify them differently.
How WESORT approaches coffee cherry sorting
WESORT’s coffee cherry sorter uses a controlled horizontal belt inspection structure. The cherries are fed into the inspection area, where front and rear cameras capture visible features from two sides. The system compares each cherry with the selected sorting criteria and uses air jets to remove cherries assigned to the reject stream.
This makes the solution suitable for applications such as removing clearly unripe green cherries, separating visibly overripe cherries and reducing abnormal fruit before the next process. The system is not intended to replace every quality-control method. It is designed to apply a defined visual standard repeatedly to the material that passes through the line.
What can be evaluated?
The exact categories must be agreed with the processor because coffee varieties, harvest conditions and commercial standards differ. A sample test may evaluate:
- Clearly green or insufficiently ripe cherries.
- Ripe cherries within the accepted color range.
- Overripe cherries with a visibly different appearance.
- Dark, shriveled or visibly damaged cherries.
- Borderline cherries that need a separate review standard.
Optical sorting evaluates visible surface characteristics. It does not automatically confirm internal fermentation, internal moisture, flavor or defects hidden beneath the skin. This distinction is important when a processor is defining the role of the machine in the complete quality-control process.
Why the sample test comes before the final machine decision
A general statement such as “we need to remove green cherries” is not enough to configure a reliable program. The plant should first decide how green is defined, whether yellow-green cherries are accepted, how overripe fruit is handled and how much borderline material can enter the good stream.
WESORT recommends a representative sample containing good ripe cherries, clearly green cherries, intermediate-color cherries and difficult surface conditions. The test should review both results: how much target material is removed and how much acceptable product enters the reject stream.
Feeding conditions also matter. Overlapping cherries, unstable spacing, excessive moisture and surface dirt can reduce the visible information available to the cameras. A result from a clean demonstration sample may therefore be different from a result in a real harvest batch.
Where does the sorter fit in the coffee process?
The coffee cherry sorter can be considered before pulping or another downstream operation when the processor wants to reduce visible maturity variation at the beginning of the process. The final position depends on the existing cleaning, conveying and collection equipment.
For plants handling multiple varieties or harvest conditions, separate sorting programs may be needed. Each program should be validated with the relevant sample rather than transferred automatically from another origin or season.
What should a coffee processor prepare?
To receive a useful recommendation, prepare the coffee cherry variety, size range, moisture condition, expected throughput, target categories, acceptable borderline material and current line layout. Representative samples are the most valuable part of the request.
Conclusion
WESORT does offer a sorting solution for coffee cherries. Its value is not simply that the machine can remove a visibly green cherry. The larger benefit is that a coffee processor can turn a subjective manual judgment into a repeatable sorting program based on the actual raw material and commercial quality standard.
When the sample test, feeding conditions and acceptance criteria are clear, the processor can make a more informed decision about machine structure, sorting settings and line integration.
