Classification by Detection Technology
Optical color sorter
Technical Principle: Utilizing high-resolution CCD cameras or photoelectric sensors to capture optical feature differences such as color, shape, and surface texture of materials for sorting.
Application Scenarios: Widely used in the food and agricultural product processing industry, such as in the processing of grains like rice and wheat, where it can precisely remove discolored grains, diseased grains, and impurities; in tea processing, it can separate yellowed leaves, tea stems, and discolored leaves; for nuts, it can screen out defective or discolored fruits and foreign objects mixed in; in plastic recycling, it can sort plastic pellets or bottle fragments of different colors, but struggles to identify internal impurities or compositional differences in the materials.
X-ray color sorter
Technical Principle: By penetrating the material with X-rays, it detects internal structures, density, and compositional differences, unaffected by surface color interference.
Application Scenario: Suitable for industrial fields requiring the detection of internal impurities or components in materials. For example, in ore sorting, it can identify metal impurities or different mineral layers within the ore; in plastic recycling, it enables precise separation of plastics containing metal impurities; and it can also be used in the food industry to detect the presence of metal foreign objects in packaged foods, addressing the limitation of optical color sorters in identifying internal material issues.
Near-infrared color sorter
Technical Principle: Utilizing near-infrared spectroscopy to analyze the chemical composition differences of materials, such as spectral variations caused by varying levels of moisture, protein, sugar, caffeine, and other components.
Application Scenario: Primarily used for component sorting of organic materials such as agricultural products and food. For instance, in coffee bean sorting, beans of different qualities can be selected based on variations in caffeine content. In grain processing, grains can be graded according to moisture or protein content. It is also applicable to traditional Chinese medicine sorting, where the quality and authenticity of herbs can be distinguished based on component differences.
Categorized by the type of material processed
Grain color sorter
Equipment Features: Designed for the size, shape, and common impurity characteristics of grain particles, it features rapid sorting speed, high processing capacity, and effectively removes discolored grains, moldy grains, insect-damaged grains, as well as impurities such as stones and weed seeds.
Application Scenario: Specifically designed for the processing of grain crops such as rice, wheat, corn, and sorghum, this system enhances the purity and quality of grains, ensures food safety, and meets the quality requirements of various consumption scenarios. For instance, high-end rice processing requires the removal of extremely tiny discolored particles to guarantee quality.
Nut Color Sorter
Equipment Features: Capable of adapting to various sizes, shapes, and surface characteristics of nuts, it can accurately identify and remove moldy, rotten, hollow, or defective nuts, as well as foreign objects. Some high-end models can also classify nuts based on maturity and plumpness.
Application Scenario: Suitable for the processing of nuts such as walnuts, macadamia, almonds, and pistachios, it enhances the grade and appearance of nut products, boosts market competitiveness, and particularly meets stringent quality standards in nut export processing.
Bean color sorter
Equipment features: Optimized based on the characteristics of bean materials, such as the size and color differences of soybeans, red beans, mung beans, etc., it can effectively remove discolored beans, moldy beans, impurities, and immature beans from beans.
Application scenario: Mainly used for the processing and production of various beans, including soybeans, red beans, mung beans, coffee beans, etc., to ensure the purity and quality of bean products and meet the requirements of different downstream industries such as food processing and beverage production for bean raw materials.
Ore color sorter
Equipment features: It has strong wear resistance and impact resistance, can adapt to harsh environments in ore processing, and can separate useful ore and gangue according to the color, luster and other characteristics of the ore. Some models can also handle large particle ore.
Application scenario: Used for sorting various types of ores such as aluminum ore, quartz sand, fluorite, calcium carbonate, potassium feldspar, etc., to improve ore grade and recovery rate, and reduce subsequent processing costs. For example, in quartz sand purification, iron containing impurities or gangue minerals can be separated.
Plastic color sorter
Equipment features: It can recognize plastics of different colors and materials. Some models combine X-ray or near-infrared technology to further distinguish the composition of plastics or whether they contain impurities. The sorting accuracy is high and can meet the purity requirements of recycled plastics.
Application scenario: Mainly used in the field of plastic recycling, sorting PET bottles, PP, PE particles, etc., separating plastics of different colors and materials, removing impurities from plastics, improving the quality and utilization value of recycled plastics, and promoting resource recycling.
Sichuan pepper color selection machine
Equipment features: It is divided into specialized models such as blue and white pepper color sorter and red pepper color sorter, which can accurately identify impurities (such as stems, leaves, seeds, snails, etc.) and defective products (such as discolored, diseased, and irregular Sichuan pepper) in Sichuan pepper.
Application scenario: Suitable for Sichuan pepper processing plants, purchasing cooperatives, food and spice trading companies, etc., used for sorting and processing green Sichuan pepper and red Sichuan pepper, improving the purity, neatness, and export quality of Sichuan pepper, and reducing export return rates.
