APEX Green Coffee Bean Color Sorter for Bulk Arabica/Robusta

Features of Green Coffee Color Sorter

This A+AI Series multi-channel industrial green coffee color sorter is customized for large-volume continuous production lines, coffee processing plants and coffee exporters. Different from the Compact M32 Small Green Coffee Color Sorter, it delivers high-throughput and high-precision sorting performance for bulk Arabica and Robusta green coffee beans.

1. High tonnage continuous processing capacity

Boasting scalable multi-channel design, the machine supports flexible capacity expansion. Each single channel reaches 300–400kg/h, and combined multi-channel configuration achieves ton-level hourly output. It perfectly matches mass production and bulk raw material upgrading of Arabica and Robusta green coffee beans.

2. AI & CCD system for accurate detection of coffee defects

Matched with high-precision CCD image acquisition system and mature deep learning AI sorting algorithm, the equipment accurately screens out moldy beans, discolored beans, broken kernels, insect-damaged beans and foreign contaminants. It is optimized specially for green coffee beans, and also compatible with common grains and seeds for auxiliary sorting work.

3. Stable 24-hour continuous industrial operation

Built with a dustproof structure adapted to coffee workshop environment, this sorter runs steadily for long-cycle nonstop production. It effectively reduces unexpected downtime and guarantees consistent sorting quality for large-volume green coffee processing lines.

4. Easy operation & low maintenance cost

It is equipped with an intuitive touch screen for quick parameter adjustment to adapt to different coffee varieties. Simple mechanical structure brings low daily maintenance workload, helping coffee processors cut labor cost and lift final coffee grade for export.

Unprocessed green coffee beans often carry impurities including twigs, insect-damaged beans, black husks and small mineral stones, which hurt your final coffee grade and commercial value.

APEX coffee bean sorting machine separates qualified coffee beans and rejects unwanted contaminants in real time. We can fully customize sorting parameters to match your raw material conditions.
✅ Clean qualified green coffee beans from finished outlet
❌ Defective beans, twigs, husks and stones discharged from reject outlet

This sorting machine brings high-precision and stable separation results. It cuts manual sorting workload, upgrades your coffee quality and maximizes profit for coffee processing plants and exporters.

Working Principle-How does it work?

Working Principle of Industrial Bulk Green Coffee Bean Intelligent Sorting System

Step-by-Step Sorting Workflow:

1. Bulk raw Arabica and Robusta green coffee beans mixed with moldy, discolored, broken and insect-damaged kernels are loaded into the top feeding hopper.
2. The feeding vibrator uniformly feeds materials along the multi-channel chute, separating beans to form stable single-particle free-falling tracks, tailored to the size characteristics of green coffee beans.
3. With calibrated stable light sources, dual-side high-precision CCD cameras capture full-surface image information of falling beans and transmit data to the signal processor.
4. The embedded AI sorting algorithm analyzes real-time visual data, rapidly identifying defective green coffee beans and foreign contaminants.
5. The signal processor immediately delivers commands to the nozzle array; compressed air precisely ejects unqualified materials into the rejected product hopper.
6. Premium intact green coffee beans naturally drop into the accepted product hopper, completing the high-throughput sorting cycle for large-volume coffee processing lines.

Performance Comparison

Green Coffee Beans Sorting

Qualified Green Coffee Beans
Complete bean shape, natural uniform surface colour without mildew, discoloration or deformity, which is the basic guarantee for stable coffee flavour in subsequent roasting procedures.

Defective Green Coffee Beans
Contains moldy beans, deep yellow / light yellow discolored beans, unripe grains, malformed and broken fragments. Our industrial multi-channel green coffee color sorter identifies tiny surface differences to completely screen out these inferior raw materials for large-volume coffee export processing lines.

Applicable Sorting Materials

Bulk granular raw materials dominated by Arabica and Robusta green coffee beans, compatible with assorted grains and seed particles for auxiliary sorting. The AI algorithm is optimized to identify surface defects for large-volume granular raw material processing.

Built with high-precision dual-sided CCD paired with mature AI deep learning algorithm, this industrial multi-channel green coffee sorting machine is customized for continuous bulk sorting of raw green coffee beans. Meanwhile, it supports most granular agricultural raw materials as secondary processing options.

Main Applicable Materials

• Coffee raw materials: Arabica green coffee beans, Robusta green coffee beans
• Expanded applicable grains: Sesame, millet, quinoa, buckwheat and other grain seeds for auxiliary sorting
• Processing form: Large-volume raw material purification, continuous industrial production for coffee exporters and coffee processing plants

Supported defect screening types

• For green coffee beans: Moldy particles, discolored beans, immature beans, malformed beans, broken fragments, insect-damaged kernels
• For miscellaneous grains: Heterochromatic grains, deteriorated particles, shrivelled seeds and foreign impurities

Designed for large coffee processing factories and bulk coffee export production lines, the equipment delivers stable high-precision sorting for continuous ton-level raw material purification, supporting nonstop 24-hour industrial production.
