In chili pepper processing, appearance, color uniformity, and cleanliness directly determine the product’s value and market acceptance.
Raw chili peppers often contain stems, stalks, spotted or discolored pods, which cannot be completely removed in a single sorting stage.
To achieve higher precision and consistent quality, GroTech introduces the Dual-Stage Chili Pepper Sorting System — two AI-powered color sorters working in series to ensure exceptional purity and efficiency.
The first GroTech color sorter performs coarse sorting.
It efficiently separates:
Chili stems and broken stalks、
Peppers with attached handles、
Foreign impurities and large debris。
After this process, clean and qualified chili peppers are transferred automatically to the second sorting stage.
The second GroTech color sorter focuses on fine sorting and defect removal.
Using multi-spectral imaging and AI visual recognition, it identifies and removes:
Spotted or blotchy chili peppers
Discolored or sunburned pods
Irregular or deformed peppers
The result is a batch of uniform, bright red, premium-quality chili peppers ready for grading and packaging.
After dual-stage sorting, GroTech systems can grade chili peppers by size and color, meeting the requirements for export, seasoning production, and food processing.
This setup not only improves sorting accuracy but also:
✅ Reduces manual labor costs
✅ Minimizes product loss
✅ Ensures consistent high-quality output

Using two color sorters in series allows each to focus on a specific task — one for impurity removal, the other for defect detection.
This division of labor significantly enhances both throughput and accuracy, ensuring every chili pepper meets top-grade visual and quality standards.
With years of experience in optical sorting technology, GroTech provides intelligent solutions tailored for chili pepper processing factories worldwide.
From stem removal to final color grading, GroTech helps manufacturers achieve cleaner, faster, and smarter chili pepper sorting — step by step.
