The five-channel color sorter is suitable for:
- Commercial seed processing plants
- Grain cleaning and packaging facilities
- Pulse and lentil processing plants
- Sunflower and edible seed operations
- Peanut and pistachio processing lines
- Specialty crop cleaning facilities
- Food ingredient preparation systems
- Contract seed and grain cleaning businesses
- Export-oriented agricultural processing plants
- Automated optical sorting and bagging lines
- Plastic granule color sorting applications
The CSR-005 can be supplied as standalone color sorting equipment or integrated with MMCTECH pre-cleaners, fine screen cleaners, gravity separators, destoners, magnetic separators, bucket elevators, conveyors, weighing systems, bagging machines, and PLC or SCADA plant automation.
How Does the CSR-005 Five Channel Color Sorting Machine Work?
The product enters through a controlled feeding system and is distributed across five optical sorting channels. As individual particles pass through the camera inspection zone, the CCD color imaging system analyzes visible characteristics such as color, shade, contrast, and surface appearance.
The machine compares the observed particles with the acceptable product parameters selected for the current recipe. When a particle falls outside the programmed visual range, the control system activates the corresponding ejector. A short and accurately timed pulse of compressed air redirects the unwanted particle into the reject stream while acceptable material continues toward the primary product outlet.
The sorting sequence includes:
- Controlled product feeding
- Distribution across five optical channels
- CCD color camera inspection
- Real-time image and color analysis
- Accept-or-reject classification
- Pneumatic rejection through 315 ejectors
- Separate accepted, rejected, and bouncing-product discharge
Stable results depend on uniform product feeding, clean camera windows, suitable lighting and background settings, correct recipe selection, stable compressed-air pressure, precise ejector timing, and appropriate pre-cleaning.
CCD Camera-Based Optical Sorting Technology
The standard CSR-005 uses CCD color camera technology to distinguish acceptable products from visually different defects and foreign material. Depending on product characteristics and available visual contrast, the optical color sorter may help remove:
- Discolored seeds and grains
- Dark or light defective particles
- Stained kernels
- Visibly damaged products
- Burned or heat-discolored material
- Mold-discolored particles
- Immature material with visible differences
- Shell fragments
- Contrasting foreign seeds
- Foreign material with a different visible appearance
- Particles outside the selected color range
The CSR-005 makes sorting decisions according to visible characteristics. It does not replace machinery that separates material according to screen size, length, shape, specific gravity, aerodynamic properties, magnetic response, or chemical composition.
Optional NIR Camera Configuration
An optional NIR camera configuration may be evaluated for applications where standard visible color inspection does not provide enough contrast between acceptable material and the target defect. Near-infrared imaging may support the identification of certain material differences that are difficult to distinguish using only visible CCD color cameras.
NIR performance is application-specific. Product and defect samples should be evaluated before selecting an NIR configuration because not every contaminant, crop defect, or foreign material creates sufficient near-infrared contrast.
Is the CSR-005 an AI Color Sorter Machine?
The CSR-005 uses programmable camera-based image processing, configurable product recipes, real-time classification, and electronically controlled pneumatic rejection. Buyers frequently search for this category using terms such as AI color sorter machine, AI-powered color sorter, vision color sorter, or automatic camera sorting machine.
Specific artificial-intelligence functions, software features, automatic learning capabilities, remote services, and image-processing options should be confirmed in the final supplied configuration. MMCTECH does not rely on unsupported AI claims when defining the technical scope of the machine.
Seed Sorting Machine for Commercial Processing Plants
The CSR-005 can function as a high-capacity seed sorting machine after appropriate mechanical cleaning, grading, aspiration, density separation, and magnetic separation stages. Its purpose is to remove visible defects and foreign particles that remain after conventional seed cleaning.
Potential seed applications include:
- Sunflower seed
- Pumpkin seed
- Watermelon seed
- Wheat seed
- Bean seed
- Chickpea seed
- Lentil seed
- Sesame seed
- Nigella or black seed
- Specialty planting seed
Mechanical seed cleaners and optical sorters perform different functions. A screen cleaner separates according to particle dimensions. An aspirator removes lightweight material. A gravity separator classifies according to density. A magnetic separator removes responsive ferrous contamination. The CSR-005 provides a visual inspection and pneumatic rejection stage.
White Wheat and Red Wheat Color Sorting
The CSR-005 provides one of its highest nominal capacities when processing wheat:
- White wheat: approximately 10,582 lbs/hour (4,800 kg/hour)
- Red wheat: approximately 8,818 lbs/hour (4,000 kg/hour)
The wheat color sorter may help remove dark kernels, stained grains, visibly damaged product, contrasting foreign seeds, and particles outside the selected visual range. White wheat and red wheat should use separately optimized sorting recipes because their normal color characteristics and target defects differ.
A complete wheat cleaning system may include pre-cleaning, fine screen cleaning, aspiration, stone removal, gravity separation, length separation, magnetic separation, optical color sorting, final inspection, weighing, and bagging.
Rye and Bulgur Color Sorting Machine
The published nominal capacity for rye is approximately 7,055 lbs/hour (3,200 kg/hour). The published nominal capacity for bulgur is approximately 8,818 lbs/hour (4,000 kg/hour).
Rye and bulgur require separate product settings because particle size, surface appearance, processing history, and acceptable color ranges differ. Bulgur applications should also be evaluated for dust level, particle uniformity, and product flow before establishing final operating capacity.
Sunflower Seed Color Sorter Machine
The CSR-005 supports several sunflower seed products with the following published nominal capacities:
- White sunflower seed: approximately 7,937 lbs/hour (3,600 kg/hour)
- Roasted sunflower seed: approximately 7,055 lbs/hour (3,200 kg/hour)
- Black sunflower seed: approximately 7,055 lbs/hour (3,200 kg/hour)
- Dakota sunflower seed: approximately 7,055 lbs/hour (3,200 kg/hour)
- Sunflower kernels: approximately 6,173 lbs/hour (2,800 kg/hour)
The machine may remove visually stained, burned, discolored, damaged, light-colored, dark-colored, or foreign particles when adequate optical contrast exists. Raw seed, roasted seed, striped sunflower varieties, black sunflower seed, and dehulled kernels require independent recipes.
Sunflower Kernel Optical Sorting
High-quality sunflower kernel production normally requires several separation stages. Screening removes oversize and undersize material. Aspiration removes lightweight shells and dust. Destoners remove heavy mineral contamination. Gravity separators remove low-density kernels. Magnetic separators help control ferrous contamination. The CSR-005 then performs visual defect removal.
Final purity depends on incoming material, pre-cleaning performance, defect visibility, product presentation, camera settings, reject sensitivity, acceptable product recovery, and the number of optical sorting passes. No fixed purity percentage should be guaranteed for every product lot.
Pumpkin Seed Color Sorter
The published nominal pumpkin seed capacity is approximately 7,937 lbs/hour (3,600 kg/hour). The optical system may help remove visibly discolored, stained, damaged, burned, foreign, or visually inconsistent pumpkin seeds.
Pumpkin seed varieties can differ in size, thickness, surface pattern, and natural color. Product feeding and recipe settings should be adjusted according to the actual variety rather than using one universal configuration.
Watermelon Seed Color Sorting
The published nominal watermelon seed capacity is approximately 6,173 lbs/hour (2,800 kg/hour). Controlled feeding is important because overlapping seeds can reduce individual camera visibility and make accurate pneumatic rejection more difficult.
Beans Sorting Machine
The CSR-005 can be used as a high-capacity beans sorting machine with a published nominal bean capacity of approximately 10,582 lbs/hour (4,800 kg/hour).
Depending on visual contrast, the machine may remove:
- Dark or light defective beans
- Stained beans
- Visibly damaged beans
- Mold-discolored particles
- Contrasting foreign beans
- Shell fragments
- Foreign material with a different color
Beans that have the same visible appearance as acceptable product but different density may require gravity separation rather than optical sorting.
Chickpea Color Sorting
The published nominal chickpea capacity is approximately 8,818 lbs/hour (4,000 kg/hour). A chickpea color sorting machine can help remove visibly darkened, stained, damaged, discolored, or foreign particles after the product has been mechanically cleaned and graded.
Lentils Color Sorting Machine
The CSR-005 can be configured as a high-capacity lentils color sorting machine. Published nominal capacities are:
- Green lentils: approximately 8,818 lbs/hour (4,000 kg/hour)
- Red lentils: approximately 8,818 lbs/hour (4,000 kg/hour)
- Yellow lentils: approximately 8,818 lbs/hour (4,000 kg/hour)
Green, red, and yellow lentils should each use an independently prepared recipe. Their normal colors, defect contrasts, background requirements, and acceptable shade ranges differ. Product-contact areas and sorting channels should be cleaned between changes to reduce cross-contamination.
Peanut Color Sorter Machine
The CSR-005 can be configured as a commercial peanut color sorter machine with the following published capacities:
- Unshelled peanuts: approximately 6,173 lbs/hour (2,800 kg/hour)
- Shelled peanuts: approximately 8,818 lbs/hour (4,000 kg/hour)
A peanut color sorter may help remove visibly darkened, stained, damaged, mold-discolored, burned, or foreign particles. Shelled and unshelled peanuts require separate feeding, camera, background, and ejector settings because their physical and visual properties differ.
Optical sorting supports visual quality control but does not replace aflatoxin testing, laboratory analysis, food-safety inspection, or other required peanut safety procedures.
Pistachio and Nut Color Sorter
The published nominal pistachio capacity is approximately 8,818 lbs/hour (4,000 kg/hour). The CSR-005 may help separate visually defective pistachios and foreign particles when sufficient color or appearance differences exist.
Pistachios and other nuts can vary naturally in color, shell condition, surface texture, and shape. Product testing helps establish the correct sensitivity, feeding rate, optical background, and acceptable recovery target.
Walnut Color Sorter Applications
The CSR-005 may be evaluated for walnut sorting, but walnuts are not assigned a specific capacity in the supplied CSR-005 capacity table. Final throughput and sorting performance should be confirmed through sample testing and engineering review.
The same evaluation requirement applies to cashews, almonds, hazelnuts, and other nut products not included in the published capacity reference.
Sesame Color Sorter
The published nominal sesame seed capacity is approximately 6,173 lbs/hour (2,800 kg/hour). Small seeds require clean optical surfaces, controlled product separation, stable feeding, and precise ejector timing.
The sesame color sorter may help remove dark seeds, light seeds, discolored particles, contrasting foreign seeds, shell fragments, and foreign materials that are visibly different from the accepted product.
Black Seed and Nigella Sorting
The published nominal capacity for black seed or nigella is approximately 4,409 lbs/hour (2,000 kg/hour). Because nigella particles are small, maintaining a controlled product layer and stable feeding is important for reliable optical inspection.
Rice Paddy Color Sorting
The CSR-005 has a published nominal rice paddy capacity of approximately 8,818 lbs/hour (4,000 kg/hour). It may help remove discolored paddy, contrasting foreign grains, and visually inconsistent particles after proper pre-cleaning.
Dust, straw, stones, broken material, and excessive foreign matter should be removed before optical sorting. Cleaner incoming product improves camera visibility, reduces ejector activity, lowers compressed-air demand, and supports higher acceptable-product recovery.
Corn Sorting Machine and Corn Color Sorter Applications
The CSR-005 may be evaluated as a corn sorting machine or corn color sorter for suitable dry corn products. Depending on visible contrast, it may help remove darkened, burned, mold-discolored, damaged, or foreign kernels.
Corn does not have a separate capacity value in the supplied CSR-005 table. Final capacity should therefore be established through product testing, crop evaluation, defect analysis, and review of the required final quality.
Soybean Color Sorter Applications
The CSR-005 may be evaluated as a soybean color sorter for removing visibly stained, discolored, damaged, darkened, or contrasting particles. Soybeans are not assigned a specific capacity in the supplied reference, so project throughput should be confirmed using representative product samples.
Salt, Chili, Cardamom and Spice Sorting
The CSR-005 may be evaluated for suitable salt, chili, cardamom, pepper, cumin, and other dry specialty products when their physical characteristics are compatible with the feeding and optical systems.
Transparent, reflective, dusty, irregular, or lightweight products may require specialized settings or equipment modifications. Capacity should not be inferred from seed or grain data when the product is not included in the published table.
Raisin, Coffee and Other Food Ingredient Applications
Raisins, coffee beans, and selected dry food ingredients may be considered after product evaluation. Sticky, semi-dried, oily, or non-free-flowing products can require a different feeding system or another optical sorter configuration.
The CSR-005 should not automatically be described as suitable for every fruit or semi-dried food application without testing the actual material.
Plastic Color Sorter Machine
The CSR-005 can be evaluated as a plastic color sorter machine for suitable plastic granules. The published nominal plastic capacity is approximately 4,409 lbs/hour (2,000 kg/hour).
It may separate plastic granules according to visible color differences when product flow is stable and individual particles can be presented clearly. Static electricity, transparency, reflectivity, particle shape, dust, and material temperature should be reviewed before final machine selection.
Belt Type Color Sorter Versus Chute Color Sorter
The CSR-005 uses channel-based free-fall optical sorting rather than a horizontal belt-type presentation system. Chute or channel sorters are commonly used for free-flowing seeds, grains, pulses, and granules.
A belt color sorter may be preferred for fragile, irregular, non-free-flowing, flat, wet, or delicate products that require horizontal presentation. Machine selection should be based on the actual product rather than assuming one technology is best for every application.
315 High-Speed Pneumatic Ejectors
The CSR-005 is equipped with 315 pneumatic ejectors. The optical control system activates individual ejectors to generate short air pulses that change the trajectory of unwanted particles without intentionally disturbing the accepted product stream.
Ejector performance depends on:
- Stable compressed-air pressure
- Clean and dry compressed air
- Correct ejector timing
- Product speed
- Particle size
- Channel loading
- Defect percentage
- Sorting sensitivity
- Routine inspection and maintenance
Increasing sensitivity can improve defect rejection but may also increase acceptable product loss and compressed-air consumption. The operating recipe should balance purity, product recovery, capacity, and operating cost.
CSR-005 Compressed-Air Requirements
The CSR-005 requires a nominal operating air pressure of approximately 87–116 psi (0.6–0.8 MPa / 6–8 bar). Published nominal compressed-air consumption is approximately 70.6–105.9 CFM (2,000–3,000 L/min).
Actual air consumption varies according to product type, reject percentage, processing rate, sensitivity settings, ejector activity, and the selected sorting recipe. The compressor package should be sized for maximum expected demand and should include sufficient reserve capacity.
A complete compressed-air system should include:
- Correctly sized air compressor
- Air receiver tank
- Moisture separator
- Compressed-air dryer
- Oil filtration
- Particle filtration
- Pressure regulation
- Pressure monitoring
- Properly sized air lines
- Minimal pressure drop between the compressor and sorter
Why Optical Grain Sorter Pre-Cleaning Is Essential
The CSR-005 should normally receive product that has already passed through appropriate mechanical cleaning equipment. Excessive dust, chaff, stones, broken particles, oversize material, undersize particles, and lightweight impurities can reduce optical performance and increase ejector workload.
A typical processing sequence may include:
- Seed or grain pre-cleaner
- Fine screen cleaner
- Aspiration system
- Destoner
- Gravity separator
- Indented cylinder separator when required
- Magnetic separator
- CSR-005 five-channel optical color sorter
- Final inspection
- Weighing, bagging, or storage
Correct pre-cleaning can improve camera visibility, reduce contamination on optical surfaces, lower reject load, reduce compressed-air use, improve accepted-product recovery, and provide more consistent final quality.
Color Sorter Versus Seed Cleaner
A seed cleaner removes material according to size, airflow, and mechanical characteristics. A color sorter removes particles according to visible appearance. The CSR-005 should generally be installed after mechanical seed cleaning rather than used as a replacement for screen and aspiration equipment.
Color Sorter Versus Gravity Separator
A gravity separator classifies particles according to density or specific gravity. It may remove hollow, lightweight, immature, insect-damaged, or low-density particles even when their color is similar to acceptable product.
The CSR-005 removes visibly different particles. Combining gravity separation and optical color sorting can provide more complete separation than relying on either technology alone.
Color Sorter Versus Magnetic Separator
A magnetic separator captures ferromagnetic and sufficiently responsive magnetic contamination. The CSR-005 detects visible differences. Dedicated magnetic separation or metal-detection equipment should be used for reliable metal-contamination control.
