Six Channel High-Speed Seed Sorting Machine and Commercial Grain Color Sorter
The MMCTECH CSR-006 Six Channel Color Sorter is a high-capacity industrial seed sorting machine manufactured for commercial seed processing plants, grain cleaning facilities, pulse processors, oilseed operations, nut processing companies, specialty crop facilities, food ingredient plants, and automated agricultural production lines. The CSR-006 combines six optical sorting channels, CCD color camera inspection, and 378 high-speed pneumatic ejectors to identify and remove discolored, stained, damaged, foreign, and visually inconsistent particles from properly pre-cleaned, dry, and free-flowing products.
The MMCTECH CSR-006 is a six-channel high-speed seed sorting machine and commercial grain color sorter designed for optical color sorting of seeds, grains, pulses, edible seeds, peanuts, pistachios, rice paddy, and suitable specialty materials. Its six-channel configuration provides a larger inspection and product-distribution area than the CSR-001 through CSR-005 models, supporting higher throughput while maintaining controlled product presentation and targeted pneumatic rejection.
According to the supplied C-6 capacity reference, nominal product capacity ranges from approximately 5,512 to 13,228 lbs/hour (2,500 to 6,000 kg/hour). Published applications include white sunflower seed, roasted sunflower seed, black sunflower seed, Dakota sunflower seed, pumpkin seed, watermelon seed, sunflower kernels, beans, chickpeas, green lentils, red lentils, yellow lentils, white wheat, red wheat, rye, bulgur, unshelled peanuts, shelled peanuts, pistachios, sesame seed, black seed or nigella, rice paddy, and suitable plastic granules.
High-Speed Sorting Machine for Industrial Processing Plants
The CSR-006 is designed for processors that require more production capacity than a small, mini, or medium-channel color sorter can provide. Its six-channel configuration allows the feeding system to distribute product across a larger optical inspection area, making the machine suitable for continuous commercial processing and higher-volume production schedules.
Typical CSR-006 applications include:
- Commercial seed processing plants
- High-capacity grain cleaning lines
- Pulse and legume processing facilities
- Sunflower seed and edible seed plants
- Wheat and cereal grain processing operations
- Peanut and pistachio sorting lines
- Specialty crop cleaning facilities
- Rice paddy processing plants
- Contract seed and grain cleaning businesses
- Automated optical sorting and bagging systems
- Suitable plastic granule sorting projects
The CSR-006 can be supplied as standalone color sorting equipment or integrated into a complete MMCTECH processing line with seed pre-cleaners, fine screen cleaners, seed graders, aspirators, destoners, gravity separators, magnetic separators, bucket elevators, conveyors, weighing systems, bagging machines, and PLC or SCADA automation.
How Does the CSR-006 Six Channel Color Sorter Work?
The product enters the machine through a controlled feeding system and is distributed across six optical sorting channels. As individual particles pass through the inspection area, the CCD color camera system analyzes visible characteristics such as color, shade, contrast, and surface appearance.
The sorter compares the observed particles with the acceptable product parameters saved for the selected crop or material. When a particle falls outside the programmed visual range, the control system activates the corresponding pneumatic ejector. A short, accurately timed pulse of compressed air changes the trajectory of the unwanted particle and directs it into the reject stream. Acceptable product continues toward the primary product outlet.
The optical sorting process includes:
- Controlled product feeding
- Distribution across six sorting channels
- CCD camera inspection
- Real-time visual analysis
- Accept-or-reject classification
- Pneumatic rejection through 378 ejectors
- Separate accepted, rejected, and bouncing-product discharge
Sorting performance depends on product preparation, feed uniformity, camera visibility, defect contrast, compressed-air stability, ejector timing, sensitivity settings, acceptable product recovery, and the number of sorting passes.
CCD Color Camera Optical Sorting
The standard CSR-006 configuration uses CCD color camera technology to inspect visible differences between acceptable products and unwanted particles. Depending on the crop, contamination, and selected sorting recipe, the machine 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 products with visible differences
- Shell fragments
- Contrasting foreign seeds
- Foreign material with a different visible appearance
- Particles outside the programmed acceptable color range
The CSR-006 makes optical sorting decisions according to visible characteristics. It does not replace equipment designed to classify products according to screen size, length, shape, density, aerodynamic behavior, or magnetic response.
Optional NIR Camera Configuration
An optional NIR camera configuration may be evaluated when visible color inspection alone cannot provide sufficient separation between acceptable product and the target defect. Near-infrared technology may help distinguish certain material differences that are difficult to identify using standard visible imaging.
NIR suitability is product-specific. Representative product and defect samples should be reviewed before selecting this option because not every contaminant, crop defect, or foreign material produces enough near-infrared contrast for dependable separation.
378 High-Speed Pneumatic Ejectors
The CSR-006 is equipped with 378 pneumatic ejectors. The optical control system activates individual ejectors to create short air pulses that remove unwanted particles from the 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 cleaning and maintenance
Increasing sensitivity may improve defect rejection, but it can also increase acceptable product loss, reject volume, and compressed-air consumption. The correct operating recipe should balance final purity, product recovery, capacity, and operating cost.
Commercial Wheat and Grain Color Sorter
The CSR-006 can operate as a high-capacity commercial grain color sorter for suitable wheat, rye, bulgur, and other free-flowing grains. Published nominal capacities include:
- White wheat: approximately 13,228 lbs/hour (6,000 kg/hour)
- Red wheat: approximately 11,023 lbs/hour (5,000 kg/hour)
- Rye: approximately 8,818 lbs/hour (4,000 kg/hour)
- Bulgur: approximately 11,023 lbs/hour (5,000 kg/hour)
The grain color sorter may help remove visibly darkened kernels, stained grains, damaged product, contrasting foreign seeds, and particles outside the selected appearance range. White wheat and red wheat should use separate recipes because their normal colors and defect characteristics differ.
A complete grain processing system may include pre-cleaning, fine screen cleaning, aspiration, stone separation, gravity separation, length separation, magnetic separation, optical sorting, final inspection, weighing, and bagging.
Sunflower Seed Color Sorter
The CSR-006 supports several sunflower products with the following published nominal capacities:
- White sunflower seed: approximately 9,921 lbs/hour (4,500 kg/hour)
- Roasted sunflower seed: approximately 8,818 lbs/hour (4,000 kg/hour)
- Black sunflower seed: approximately 8,818 lbs/hour (4,000 kg/hour)
- Dakota sunflower seed: approximately 8,818 lbs/hour (4,000 kg/hour)
- Sunflower kernels: approximately 7,716 lbs/hour (3,500 kg/hour)
The machine may help remove visibly discolored, stained, burned, damaged, light-colored, dark-colored, or contrasting foreign particles. Raw sunflower seed, roasted seed, striped varieties, black sunflower seed, and dehulled kernels should each use independently optimized recipes.
Pumpkin and Watermelon Seed Sorting
The published nominal pumpkin seed capacity is approximately 9,921 lbs/hour (4,500 kg/hour). The published nominal watermelon seed capacity is approximately 7,716 lbs/hour (3,500 kg/hour).
Pumpkin and watermelon seed varieties can differ in thickness, size, color, surface pattern, and reflectivity. Controlled feeding is important because overlapping seeds can reduce individual camera visibility and interfere with accurate pneumatic rejection.
Bean Sorting Machine and Chickpea Color Sorter
The CSR-006 provides high commercial capacity for beans and chickpeas:
- Beans: approximately 13,228 lbs/hour (6,000 kg/hour)
- Chickpeas: approximately 11,023 lbs/hour (5,000 kg/hour)
A bean or chickpea color sorter may help remove visually stained, darkened, light-colored, damaged, mold-discolored, or foreign particles. Defects that look similar to acceptable product but have a different density may require gravity separation before optical sorting.
Lentil and Pulse Color Sorting
The CSR-006 can be configured for high-volume pulse processing. Published nominal capacity for green lentils, red lentils, and yellow lentils is approximately 11,023 lbs/hour (5,000 kg/hour) for each product.
Each lentil variety requires a separate recipe because its acceptable color range, target defects, background contrast, and sensitivity requirements differ. The channels and product-contact surfaces should be cleaned during crop changes to reduce cross-contamination.
Peanut and Pistachio Color Sorting
Published capacities for nut-related applications include:
- Unshelled peanuts: approximately 7,716 lbs/hour (3,500 kg/hour)
- Shelled peanuts: approximately 11,023 lbs/hour (5,000 kg/hour)
- Pistachios: approximately 11,023 lbs/hour (5,000 kg/hour)
Optical sorting may help remove visibly darkened, stained, damaged, mold-discolored, burned, or foreign particles. Shelled peanuts, unshelled peanuts, and pistachios require separate feeding and optical settings because their shapes, surfaces, and normal color ranges differ.
Optical sorting supports visual quality control but does not replace laboratory analysis, aflatoxin testing, food-safety inspection, or other required quality-control procedures.
Sesame and Black Seed Sorting
The CSR-006 has a published nominal sesame capacity of approximately 7,716 lbs/hour (3,500 kg/hour). The published nominal black seed or nigella capacity is approximately 5,512 lbs/hour (2,500 kg/hour).
Small seeds require stable feeding, clean optical surfaces, controlled particle separation, and precise ejector timing. Their lower capacity compared with beans or wheat reflects the need to present individual particles clearly to the camera system.
Rice Paddy Color Sorter
The published nominal rice paddy capacity is approximately 11,023 lbs/hour (5,000 kg/hour). The CSR-006 may help remove discolored paddy, contrasting foreign grains, and visually inconsistent particles after suitable pre-cleaning.
Dust, straw, stones, broken material, and excessive foreign matter should be removed before optical sorting. A cleaner incoming product improves camera visibility, reduces unnecessary ejector activity, lowers compressed-air demand, and supports better product recovery.
Soybean and Corn Color Sorter Applications
The CSR-006 may be evaluated as a soybean color sorter or corn color sorter when representative samples, defect characteristics, required throughput, and feeding behavior are reviewed. Soybeans and corn are not assigned individual capacity values in the supplied C-6 reference, so final throughput should be confirmed through product evaluation.
Depending on visible contrast, optical sorting may help remove stained, discolored, damaged, burned, mold-discolored, or foreign kernels.
Plastic Granule Color Sorting
The CSR-006 may be evaluated for suitable plastic granules at a published nominal capacity of approximately 5,512 lbs/hour (2,500 kg/hour).
Plastic sorting performance depends on particle color, transparency, reflectivity, static electricity, shape, dust, temperature, and feeding behavior. Product testing is recommended before confirming final capacity and machine configuration.
Chute Color Sorter Versus Belt Color Sorter
The CSR-006 uses a channel-based free-fall sorting arrangement. This design is generally suitable for dry and free-flowing seeds, grains, pulses, and granules.
A belt-type color sorter may be more appropriate for fragile, flat, irregular, sticky, semi-dried, or non-free-flowing products that require horizontal presentation. The correct optical sorter should be selected according to the material rather than assuming one design is suitable for every application.
Why Pre-Cleaning Is Important Before Optical Sorting
The CSR-006 should normally receive product that has already passed through suitable mechanical cleaning equipment. Excessive dust, chaff, stones, broken particles, oversize material, undersize particles, and lightweight impurities increase the workload on the optical and pneumatic systems.
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-006 six-channel color sorter
- Final inspection
- Weighing, bagging, or storage
Correct pre-cleaning can improve camera visibility, reduce contamination of optical surfaces, lower ejector workload, decrease compressed-air consumption, improve acceptable-product recovery, and support more consistent final quality.
Color Sorter Versus Seed Cleaner
A seed cleaner removes impurities according to screen size, airflow, and mechanical characteristics. A seed color sorter removes particles according to visible appearance. The CSR-006 should generally be installed after mechanical cleaning rather than used as a replacement for screen and aspiration equipment.
Color Sorter Versus Gravity Separator
A gravity separator classifies material according to density or specific gravity. It may remove hollow, immature, insect-damaged, lightweight, or low-density particles even when their color resembles acceptable product.
The CSR-006 removes visually different material. Using gravity separation before optical sorting can provide more complete defect removal than relying on either machine alone.
Color Sorter Versus Magnetic Separator
A magnetic separator captures ferromagnetic and sufficiently responsive magnetic contamination. The CSR-006 identifies visible differences. Dedicated magnetic separation or metal-detection equipment should be used for reliable metal-contamination control.
CSR-006 Compressed-Air Requirements
The CSR-006 requires a nominal operating pressure of approximately 87–116 psi (0.6–0.8 MPa / 6–8 bar). Published nominal compressed-air consumption is approximately 88.3–127.1 CFM (2,500–3,600 L/min).
Actual air demand depends on product type, defect percentage, processing rate, sorting sensitivity, ejector activity, and the selected recipe. The compressor system should be sized for maximum expected demand with suitable reserve capacity.
A complete compressed-air package should include:
- Correctly sized air compressor
- Air receiver tank
- Moisture separator
- Compressed-air dryer
- Oil filtration
- Particle filtration
- Pressure regulator
- Pressure monitoring
- Correctly sized air lines
- Minimal pressure loss between compressor and sorter
North American and International Electrical Standards
The CSR-006 has a nominal machine power requirement of approximately 4.02 HP (3.0 kW). For North American and international installations, the machine can be configured for 208 / 240 / 480 VAC – 3 Phase – 50/60 Hz, subject to final project engineering.
The compressor, elevators, feeders, conveyors, dust-control equipment, and other auxiliary machinery require separate electrical power and should be included when calculating the total connected load.
Machine Weight, Channel Size and Noise Level
The CSR-006 has a nominal machine weight of approximately 2,579 lbs (1,170 kg). The published nominal channel measurement is approximately 4.72 × 1.18 in (120 × 30 mm).
The nominal machine noise level is approximately 80 dB. Total workplace sound can be higher when the compressor, elevators, conveyors, and other processing machinery are operating.
