Introduction to Color Sorter

Colour sorters or color sorters (sometimes called optical sorters, digital sorters, or electronic colour sorters) are machines used on production lines in bulk food processing and other industries. They sort items by color, detecting passing items' colors and using mechanical or pneumatic devices to divert items with colors outside the acceptable range or to create distinct groups.

Types of Color Sorter Machines

Chute Color Sorter

A chute sorter has rows of optical sensors all along its product chutes, which operate simultaneously to ensure comprehensive and accurate detection. These machines can sort a high volume of material quickly, making them ideal for high-capacity production lines.

Belt Color Sorter

This type of sorter uses a conveyor belt that moves the material past a single optical sensor. As the objects don’t move as much, they’re far less prone to breakage, so many businesses use this type of sorter for delicate items.

Optical Color Sorter

Optical color sorting uses lasers or cameras to sort bulk products automatically. This non-destructive machine can recognize a product’s structure, shape, defect size, and chemical composition and has a 100% inspection rate.

Application of Color Sorter

Food Industry

Color sorters can be divided into different types according to different applications. They can be applied in the food processing industry such as coffee, nuts, vegetables, and tea. These color sorting machines can also be called coffee color sorter, nut color sorter, and tea sorter machine. The purpose of color sorting machines in the food industry is to separate discolored, toxic, and unripe. Compared to manual sorting, color sorting machines have high efficiency and low cost.

Agriculture Industry

The color sorters in the agriculture industry are mainly used to classify grains and the rice color sorter machine is the most popular. The rice sorter usually adopts advanced CCD optical sensors to separate rice according to its color of it. Color sorters can also be used in other areas such as wheat, corn, peanuts, and beans.

Components of Color Sorter

Feeder: To achieve the stability and regulation of flow.
Groove: Get a uniform tea flow and a constant tea grain speed.
Fluorescent Lamp: Provides a specified light frequency area, stable performance of the light source.
Background Plate: Contrasts or transmission light that shines on the tea stream and reflects it to the photoelectric sensor.
CCD/CMOS Device: Using the difference in color between genuine tea grains and different color tea grains, high-speed image scanning of flowing tea streams is carried out.
Photoelectric Sensor: Converts the optical signal into a digital electrical signal and transmits it to the electrical signal processing system.
Signal Processing and Integrated Circuit System: To complete the identification processing of electrical signals, the release of instructions and drivers for functional components, etc.
Injection Valve: Executes the opening and closing instructions of the electrical signal processing system and blows the different colored tea grains.
Automatic Cleaning Mechanism: Automatic cleaning of dust on dustproof glass.
Compressed Air Conditioning Device: Pressure regulation and further filtration of compressed air provided by the air compression system, and the provision of qualified compressed air to gas systems such as injection valves and automatic cleaning mechanisms.

Working Principle of Color Sorter

A color sorter utilizes innovative technology to identify the characteristics of raw material going through its feeding hopper as part of a bulk processing line. First, the operator places the material into the hopper, where vibrations move it down the chute. Then, a pneumatic or mechanical ejection device separates the material based on size and quality, ejecting defective material.
Next, the selected material slides into a sorting chamber where a high-speed CCD chip performs precise, high-definition imaging to form a video signal output and display to complete the sorting based on color differences. These machines identify and eliminate defective, imperfect, and diseased elements based on health requirements and the strictest food hygiene standards.

Tips for Color Sorter

●Choose products according to output.
●Pay attention to the net selection rate (refers to the ratio of the weight of the available part of the food raw materials after the initial processing to the total weight of the raw materials before processing). Generally, the higher the purity of the selection, the higher the value. This should be selected according to your own requirements.
●The budget determines the configuration of the color sorter. It is recommended to buy the color sorter that is most suitable for you within a limited budget.
●After-sales service: Good suppliers, with perfect after-sales service, promptly solve problems encountered during use.
●If there is a problem with the color sorter and the maintenance is not timely, it will inevitably cause the entire production line to stop working and cause heavy loss.

Ultimate FAQ Guide to Color Sorter

Q: What is a color sorter?

A: Colour sorting machines, as the name suggests, enable the sorting of individual items on a production line by colour. Most colour sorting machines nowadays use high-resolution optical sensors to identify items, and either a pneumatic or mechanical ejection device to expel unwanted items from the main line.

Q: What are the benefits of a color sorter machine?

A: This product can be used in the farming, grain industry, chemical, medicinal and other sectors. The colour sorting machine saves work, saves resources, and provides high efficiency with considerably lower production costs as compared with manual sorting.

Q: In what fields is Color Sorter mainly used?

A: Colour sorters are mostly used in sorting grain (agricultural products). The rice sorting industry is the first big market. The rice sorting technology is according to the color differences of rice (husked paddy) materials, using a high-resolution CCD optical sensor to separate stones, black rice, etc. It is the final step after polishing rice with a rice polisher. The second sorting market is in use for coarse cereals, such as wheat, corn, peanuts, different kinds of beans, sesame seeds, etc. This can also include grains, seeds, cereals, pulses, coffee, and nuts. The color sorters can also be used to remove harmful plastics and metals.

Q: What are the principles of color sorter machine?

A: The working principle of the CCD color sorter is to determine the color depth and light transmittance of the material by taking pictures of the material, compare the amplitude of the light change, and eject the material whose amplitude exceeds the set value. When the color sorter starts to work, the materials in the feeding hopper are evenly distributed to each channel under the action of the vibrator. The falling materials are detected by the CCD camera in the sorting room. If unqualified materials or impurities are found in the materials, the main control machine will start the spray valve to blow them down into the defective hopper.

Q: Why is a color sorter beneficial?

A: ● Multi-Functional
A commodity that is particularly suitable for rice, tea, sesame, beans, seed, raisin, or other areas of colour. This product can be used in the farming, grain industry, chemical, medicinal and other sectors.

Q: What are the common applications of a Color Sorter?

A: Color sorters are integral to many businesses, particularly in the agricultural and food processing industry. For example, a color sorter can display seed images and swiftly sort through grains and harvested products with rapid efficiency, including: Corn, Beans, Nuts, Fruits, Seeds, Peanuts, Plastic, Salt, Wheat, Tea, Dehydrated vegetables, Spices, Snacks, Oats, Coffee beans, etc. In addition, the recycling, diamond, and mining industries, as well as many other companies use them to sort minerals, sand, stone, and ore.

Q: How much space is needed to install a Color Sorter?

A: Enough space around the color sorter is necessary for debugging and maintenance, and the recommended space around the sorter is above 60cm. As grounding the sorter can avoid the lightning stroke damage to the machine or any personal damage due to current leakage which resulted by misoperation, users are recommended to embed ground wire before welding the platform.

Q: What are the installation environment requirements for Color Sorter?

A: As the external light will directly affect the color separation, it is necessary to keep the color sorter away from strong light and forbidden to put a ceiling lamp above it. Enough lighting, of course, is necessary for the operation and maintenance. Like the common domestic appliances, in terms of ambient temperature, the color sorter is required to be 0-40 Celsius.

Q: What are the components of a Colour sorting machine?

A: The primary components of a color sorter include the feeding system, where the material enters the channel or chutes, the main control machine, and the optoelectronic system, containing a sorting cabinet, light source, cameras, reflectors, etc.

Q: What mandatory maintenance does the Color Sorter require?

A: Keeping all relevant areas of the optical sorter clean and mechanically maintained will have the biggest impact on uptime and performance. This includes monitoring and, if required, adjusting the tracking of the high-speed acceleration belt, its bearings and areas around and below the return idlers, tail and head pulleys. The splitter roller inside the catcher hood as well as the air valve/nozzle assembly are spots where materials can build up over time as well. Keeping those areas clean and easily accessible to maintenance personnel will reduce the risk of jams.
The halogen lamps that illuminate the sensing zone have a limited lifetime and must be replaced eventually. On older machines, manual monitoring of the light intensity might be required. Newer units have the capability to alert the operator when lamps should be replaced. While some optical sorters available in the marketplace will keep sorting when halogen bulbs have burned out, they will do so at reduced efficiency.
Especially during rain and snow events, the air ejectors will generate mist and liquid splatter that will settle over time on the glass surfaces that cover the halogen light assemblies as well as the sensor itself. Keeping those surfaces as clean and transparent as possible will ensure the maximum amount of light reaches the near-infrared (NIR) color spectrometers.

Q: In the summer, does the Color Sorter need to be cooled by air conditioning?

A: In the summer, air conditioning units help to keep the sensor housings as well as the operator touch-screen control panel from overheating. The dust filters for those units need to be checked, cleaned and possibly replaced on a regular basis. Extended exposure to high temperatures is a sure way to shorten the lifetime of the internal electronics.

Q: How to extend the service life of Color Sorter?

A: An important aspect to increase the longevity of optical sorters is providing ultraclean compressed air that is free of moisture, oil and dust. Monitor the air quality coming from the compressor on a regular basis, otherwise the internal valve mechanisms could fail, causing the valves to remain in the open or closed position.

Q: What are the precautions for the use of the color sorter?

A: ●When operating the keyboard, you should touch the keys lightly and do not hit hard or touch with a hard and sharp object.
●Hard objects are not allowed to wipe the channel, otherwise it will damage the surface of the channel and affect the color selection effect.
●When cleaning the channel sorting room, receiving hopper, etc. with an air gun, never blow the air gun mouth toward the nozzle direction.
●The operation of the Growking Optoelectronic color sorter should strictly follow the operating procedures. Only after confirming that the preparations have been completed can it be turned on; the shutdown should also be performed in the shutdown sequence, and it cannot be turned off at will.
●Prevent strong electromagnetic interference in site and around the site, so users must use iron pipes for self-connected incoming and outgoing feeding pipes and exhaust pipes. Plastic pipes and other non-metallic pipes should not be used, and it should have good grounding, and the grounding resistance should be less than 10Ω.

Q: How do I know when the Color Sorter needs maintenance?

A: For the wearing parts, if the small belt of the cleaning brush is worn out, you need to consider whether to replace it. Test each valve. If abnormal, repair or consider replacing the solenoid valve. Depending on the conditions of use, the use time of the filter element varies, and it is generally replaced once a year.

Q: How accurate is a color sorter in detecting colors?

A: Sensors see color differences to detect a wide range of defects, including fruit that's over-ripe, diseased, bird-pecked, and decayed. High sorting accuracy of up to 95% reduces loss of saleable product.
