The optical sorter is an intelligent sorting tool in modern industrial production and is playing an increasingly important role. It uses advanced optical principles to accurately screen and classify various materials.

The working principle of the optical sorter is based on the different reflection and absorption characteristics of materials to light. When a specific light source irradiates the material, the optical sorter detects the reflected light through an optical sensor. For example, in some ore sorting scenarios, different minerals have different reflectivities to light, and the optical sorter can select the target mineral from the mixed ore based on this characteristic.

In terms of type, the optical sorter is mainly divided into two types: sorting according to the color of the object and sorting according to the shape of the object. Regardless of the type, it is inseparable from the collaboration of high-speed cameras and image processing systems. High-speed cameras quickly capture the optical information of the material, and the image processing system analyzes and processes this information to quickly and accurately determine whether the material meets the screening criteria.

The application field of the optical sorter is extremely wide. In the food processing industry, it can be used to sort fruits, vegetables, nuts and other foods. For example, it can select fruits with poor color and damage to ensure the high quality of fruit products and enhance the market competitiveness of products; in the pharmaceutical industry, optical sorters can screen materials such as drug particles and capsules to ensure the purity and consistency of drugs and ensure the safety of drug use; the sorting and screening of chemical raw materials are also inseparable from optical sorters, which can improve the quality of chemical products by removing impurities; in the field of agricultural product processing, optical sorters can improve the purity of agricultural products such as grains and beans; even in the field of environmental protection, optical sorters can be used for garbage recycling and treatment, separating recyclables from other garbage, improving recycling efficiency, and promoting resource recycling.

Compared with traditional screening methods, optical sorters have significant advantages. Its high efficiency is reflected in the ability to quickly complete the sorting of materials, greatly improving production efficiency; high precision, can accurately identify subtle differences in materials, and ensure screening quality; it can also save a lot of manpower and reduce the labor intensity and cost of manual sorting; and it adopts advanced technology, high reliability, stable equipment operation, and reduces the frequency of failures. With the continuous advancement of science and technology, optical sorters will continue to upgrade and play a greater role in more fields.

The core of the optical sorter is to utilize the differences in the optical properties of materials, and to achieve efficient and accurate automatic sorting through photoelectric detection and intelligent processing technology, which plays an important role in the fields of ore processing and agricultural product grading.

The work flow of the optical sorter starts with material transportation. The material enters the detection area of the optical sorter at high speed in a uniform single layer state through a vibrating feeder or a belt conveyor. In this critical area, the high-precision optical detection system begins to play a role. It consists of multiple high-resolution photoelectric sensors and light sources. The light source emits light of a specific wavelength to the material, and the light reflected or transmitted by the surface of the material is received by the photoelectric sensor. Materials of different types or qualities have different reflection, absorption, and transmission capabilities for light due to their chemical composition, surface structure and other factors, thereby generating unique optical signals, such as color differences, spectral reflectivity differences, etc.

The optical signals captured by the optical detection system are converted into electrical signals and transmitted to the intelligent control system. The system has built-in powerful algorithms and databases, which can quickly analyze and process these electrical signals, compare them with pre-set standard parameters, and determine the category and quality of the materials. Once the target material to be sorted is confirmed, the control system will immediately issue a command to trigger the actuator. The actuator usually uses a high-pressure air valve or a pulse jet device to eject a high-pressure airflow in a very short time, blowing the target material away from the conveying flow and making it fall into the designated collection area, while the material that does not meet the requirements continues to enter other collection areas with the conveying flow, thus completing the entire sorting process.

With the continuous development of technology, the detection accuracy and sorting efficiency of optical sorters continue to improve, and in the future, they will be more widely and intelligently applied in more industries.

The most prominent feature of the optical sorter is high-precision screening. It uses advanced optical detection technology to accurately identify the color, shape, size, material and other characteristics of the material. Taking the food industry as an example, when screening raisins, the optical sorter can keenly distinguish the dull color, shriveled particles and impurities mixed in it, and accurately select high-quality raisins to ensure uniform and stable product quality.

The screening efficiency of the optical sorter is extremely high. The traditional manual screening method is slow and easily affected by factors such as fatigue. The optical sorter can process several tons or even tens of tons of materials per hour with its high-speed transmission device and fast-response detection system. In the field of ore sorting, an optical sorter can process tens of tons per hour, greatly improving the mining and processing efficiency of mineral resources.

Its intelligence is also a highlight. The optical sorter is equipped with an intelligent operating system, which can flexibly set the screening parameters according to the screening requirements of different materials. The operator only needs to enter relevant instructions on the control interface, and the machine can automatically complete the screening work, and can monitor the screening process in real time. Once an abnormality occurs, it will issue an alarm and automatically adjust it in time, reducing manual intervention and labor intensity.

Optical optical sorters have a wide range of applications. They can be used in many industries such as food, medicine, chemical industry, mining, environmental protection and recycling. In pharmaceutical production, they are used to screen medicinal materials to ensure the quality of medicines; in the field of environmental protection and recycling, they can sort waste plastics, metals, etc. to help recycle resources.

The optical optical sorter has good stability and durability. It uses high-quality materials and precision manufacturing processes, and key components have been specially treated to adapt to harsh working environments such as high temperature, humidity, and dust. It can operate stably for a long time, reduce equipment failures and maintenance costs, and provide strong guarantees for the company's continued efficient production.
