APEX AI Deep Learning Green/Roasted Coffee Bean Sorting Machine

Features of Coffee Bean Sorting Machine

The Model M32+AI is a compact vertical mini AI grain color sorter, customized for small-batch production lines, startup processing workshops, lab sample inspection and high-grade personalized coffee & grain deep processing. Unlike the A+AI Series high-capacity industrial Green Coffee Color Sorter Built for Mass Production, it delivers micron-level precise sorting performance within a greatly reduced installation footprint.

1. Space-saving compact layout

Boasting a tiny occupied area and free flexible layout installation, this unit solves the space shortage pain point of large industrial color sorters. It fits perfectly in small workshops, experimental testing rooms and multi-variety intermittent small-batch production of coffee beans and miscellaneous grains.

2. AI-powered precise elimination of micro defects

Matched with high-definition CCD image acquisition system and built-in deep learning AI algorithm, the equipment accurately screens out micro mold spots, faded discolored grains, underdeveloped immature kernels and trace stained impurities, targeting specialty coffee beans while being compatible with most common small granular grains.

3. Low investment & user-friendly flexible operation

It comes with low running power consumption, one-touch intelligent operation interface and low daily maintenance workload. With very low upfront procurement cost, it supports specialty coffee bean purification, high-end small-batch grain finishing and customized raw material quality upgrading for individual processors.
Model M32+AI mini intelligent color sorter empowers small manufacturers and individual workshops to stably produce high-purity premium grains and specialty coffee beans, fully satisfying flexible small-lot, high-precision personalized processing requirements.

Raw Green Coffee Bean Sorting Demo | Remove Twigs, Stones & Defective Beans

Watch our live sorting test for raw green coffee beans.
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.

Roasted Coffee Bean Sorting Demo Video

Watch our sorting test for roasted coffee beans.
Mixed roasted coffee often contains under-roasted green beans, corn kernels and off-color particles, which downgrade your finished coffee and hurt your brand reputation.

✅ Clean qualified roasted coffee beans from finished outlet
❌ Under-roasted beans, corn and defective particles discharged from reject outlet

This sorter delivers stable, high-precision separation for roasted coffee batches. It reduces manual picking work, stabilizes your premium coffee grade and improves yield for roasters and coffee exporters.

Working Principle-How does it work?

Working Principle of Model M32+AI Mini Coffee & Grain Intelligent Sorting System

Step-by-Step Sorting Workflow:

1. Raw coffee beans or mixed miscellaneous grains containing moldy particles, discolored grains and immature kernels are poured into the top feeding hopper.
2. The feeding vibrator conveys materials evenly down the streamlined chute to form stable single-particle free falling tracks, adapting to the small particle characteristics of coffee beans.
3. Under matched stable light sources, dual-side high-definition cameras capture complete surface image data of falling particles and transmit data to the signal processor.
4. The built-in AI deep learning algorithm analyzes real-time image information, quickly marks defective coffee beans and impurity particles with tiny flaws.
5. The signal processor instantly sends instructions to the nozzle group, and compressed air accurately blows defective materials into the rejected product hopper.
6. High-quality qualified coffee beans and clean grains fall naturally into the accepted product hopper, finishing the whole compact high-precision sorting process for small-batch production.

Performance Comparison

Green Coffee Beans Sorting

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

Defective Green Coffee Beans
Contains moldy beans, deep yellow / light yellow discolored beans, unripe grains, malformed and broken fragments. M32+AI high-precision AI algorithm identifies tiny surface differences to completely screen out these inferior raw materials at the initial processing stage.

Roasted Coffee Beans Sorting

Qualified Roasted Coffee Beans
Even baking degree, plump and intact bean structure, consistent surface luster, greatly improving the taste uniformity of hand-brewed coffee and commercial finished coffee products.

Defective Roasted Coffee Beans
Mainly includes over-burnt carbonized beans, under-roasted lighter grains, cracked fragments and mechanically damaged beans. The mini M32+AI equipment realizes precise separation of good and bad roasted beans for small-batch coffee roasting production.

Applicable Sorting Materials

Mini-sized granular materials dominated by green coffee beans & roasted coffee beans, compatible with various small miscellaneous grains and seed particles; AI algorithm targets tiny surface defects of small-particle materials.

Built with lightweight dual-sided CCD matching mini iterative AI deep learning algorithm, Model M32+AI compact coffee bean sorting machine is primarily customized for the whole-process sorting of green raw coffee beans and roasted coffee beans, meanwhile compatible with most small granular food raw materials.

Main Applicable Materials

• Coffee raw materials: Green unroasted coffee beans, medium/well roasted coffee beans
• Expanded applicable grains: Sesame, millet, quinoa, buckwheat, various small seeds and miniature granular miscellaneous grains
• Processing form: Small-batch raw material purification, laboratory sample screening, handmade boutique grain finishing

Supported defect screening types

• For coffee beans: Moldy particles, yellow discoloration, immature beans, malformed, broken fragments, burnt & under-roasted grains
• For miscellaneous grains: Heterochromatic grains, deteriorated particles, shriveled seeds and tiny foreign impurities

Designed for small workshops, coffee roasteries and laboratory testing scenarios, the equipment realizes high-precision fine sorting for small-batch premium food raw materials without large site occupation.
