A Turkish packer was losing revenue. Their green peppers went to the right channel. Their red peppers went to the right channel. But the peppers in between — the ones that were neither fully green nor fully red — kept ending up in the wrong pack. Here's how an optical sorter solved the problem.
One Packer's Problem: The Cost of "Almost"
Recently, a Turkish customer approached Fstsort with a specific challenge. They were processing different varieties of tomatoes and green peppers — and they were struggling with color sorting.
The issue wasn't obvious at first. Their green peppers were clearly green. Their red peppers were clearly red. But a significant portion of their harvest fell somewhere in between — peppers that had started changing color but hadn't fully turned.
For a manual sorter, these "in-between" peppers are a problem. One worker might call it green and send it to the green channel. Another might call it red and send it to the red channel. Neither worker is wrong — but the inconsistency was costing the packer money.
The result: mixed packs, rejected shipments, and revenue lost to inconsistent color judgment.
The customer needed a solution that could make the same call every time — no matter who was operating the line, no matter what time of day, no matter how fast the line was running.
The Real Challenge: Color Judgment Is Subjective
This Turkish packer's problem isn't unique. It's the same challenge that packers face wherever bell peppers are graded by hand.
Bell peppers change color as they ripen. They start green, then transition through stages of green-yellow, yellow-orange, orange-red, and finally full red, yellow, or orange.
At each stage, the color is slightly different. And at the transition points — where a pepper is 70% green and 30% red — different workers make different calls.
Manual Sorting Problem | The Result |
|---|---|
Different workers, different standards | One person's "green" is another person's "red" |
Same worker, different time of day | Morning judgment and afternoon judgment don‘t always match |
Fast-moving line | No time to examine each pepper carefully — quick decisions lead to errors |
High volume pressure | When the line is full, accuracy drops |
For packers supplying supermarkets or export markets, where color consistency is non-negotiable, this inconsistency is a business risk.
What an Optical Sorter Does Differently
An optical sorter doesn't have this problem. It uses high-speed cameras to inspect every pepper, every time, with the same standard.
Once the color parameters are set — this is green, this is red, this is yellow, this is orange — the machine applies them consistently, without fatigue, without distraction, without subjective judgment.
What the Fstsort optical sorter delivers:
· Green, red, yellow, orange — sorts by ripeness and color grade with consistent accuracy
· External defects — detects scars, sunburn, rot, insect damage, mechanical marks
· Zero physical contact — cameras only, no damage to delicate skin
· High speed — matches the throughput of roller or weight sorters
· Modular integration — combines with roller sizers or weight sorters for complete quality control
The system processes peppers continuously — no breaks, no shift changes, no inconsistency. Every pepper is evaluated against the same standard.
The Solution: A Complete Packing Line
After discussing the customer's specific needs — the varieties they grow, the markets they serve, and the volumes they process — Fstsort recommended a tailored solution.
The line includes:
· Soft nylon brushes — gentle cleaning without damaging the product
· Air drying — removes surface moisture before sorting
· Optical color sorting — separates green, red, yellow, and orange with consistent accuracy
· Large packaging tables — each color grade exits to its own packing station, eliminating cross-contamination
The result: green peppers go to the green channel, red peppers to the red channel, and every pepper finds its right buyer at the right price.

The Cost of "Almost"
Inconsistent color sorting isn't a minor issue. It's a direct hit to your revenue.
A red pepper that goes to the green channel sells at a discount. A green pepper that goes to the red channel results in a customer complaint. And the in-between peppers — the ones that different workers sort differently — are where most of the losses happen.
The technology exists to eliminate the guesswork. The question is whether your line is still relying on subjective judgment.
