Coffee sorting changes with green and roasted beans, screen size, defect mix and the buyer’s tolerance for good beans in the reject stream. A sample test is the safest way to see what the sorter can actually separate.
Bean type, screen size, defect examples, feed condition and normal hourly throughput.
Black, sour, immature, insect-damaged and visibly off-color beans in the same condition as production.
The reject stream should be checked carefully, because over-rejecting good beans can cost more than the defect itself.
BEFORE QUOTING
Coffee buyers usually care about both defect removal and yield loss. The sample review should make both sides visible.
Tell us whether you process green or roasted coffee, which defects must be removed and the throughput required.
Share the material you process, the visible defects you need to remove and your target throughput. If you can send a representative sample, we can plan the selection around real test conditions.
