Optical Sorting Machine is a high-precision automatic sorting equipment based on image recognition and intelligent control technology. It is widely used in solid waste recycling, food processing, plastic sorting, mineral metallurgy, agricultural processing and other fields. The equipment uses high-resolution optical sensors (such as CCD cameras, near-infrared NIR, short-wave infrared SWIR) and high-speed jet systems, combined with image recognition and artificial intelligence algorithms, to achieve rapid recognition and automatic separation of multi-dimensional features such as material color, shape, size, surface defects and material.

The working principle of the optical sorting machine mainly includes three core links: material supply, optical recognition and airflow removal. First, the material is transported to the conveyor belt or free fall area through a uniform feeding device and enters the optical recognition area; then, the high-speed camera or multi-spectral imaging device scans the material frame by frame, and identifies and analyzes its appearance characteristics or material through the image processing system; finally, the control system determines which materials should be retained or removed, and quickly controls the corresponding jet valve action to remove impurities or foreign matter that do not meet the standards, thereby achieving automatic sorting.

Modern optical sorting machines use advanced AI deep learning technology, which can continuously optimize recognition models and adapt to complex and diverse sorting needs. It can not only accurately distinguish plastics of different colors and materials, and separate organic and inorganic substances, but also detect spots, mildew, foreign matter and other defective products in food industries such as fruits, vegetables, nuts, and grains, effectively ensuring product quality and safety.

Compared with traditional manual or mechanical sorting methods, optical sorting machines have many advantages such as high precision, fast speed, high efficiency, low pollution, and manpower saving. Its sorting accuracy can reach more than 99%, and its processing capacity ranges from several tons to tens of tons per hour, which is suitable for various production scales from small workshops to large industrial assembly lines.

The equipment has a compact structure and modular design for easy installation and maintenance. It can be configured with a variety of functional modules according to different customer needs, such as dust removal system, metal detection, electromagnetic sorting, etc., to further expand its application range and sorting effect.

Optical sorting machines are one of the core equipment for realizing industrial automation and intelligent sorting, and play an increasingly important role in many industries such as environmental protection, food, and resource recycling.

Optical Sorting Machine is an efficient and automated equipment that uses optical recognition and intelligent control technology to realize automatic identification and separation of materials. Its working principle is mainly based on physical characteristics such as color, shape, size and material. It uses high-speed image acquisition system and intelligent algorithm to make real-time judgments to achieve accurate sorting. It is widely used in solid waste recycling, food processing, ore processing, plastic classification and other fields.

The core components of the photoelectric sorting machine include feeding system, optical detection system, image processing system, blowing system and control unit. First, the material is evenly distributed on the conveying path through a conveyor belt or a vibrating feeding device to form a single-layer fluidized state, which is conducive to subsequent identification.

Next, the optical detection system starts working. The system usually consists of a high-resolution industrial camera, an LED light source and a spectral sensor, which can capture the image information of each material particle in real time. Some high-end equipment is also equipped with near-infrared (NIR), short-wave infrared (SWIR) or multi-spectral imaging systems to analyze the reflectance spectrum of the material to distinguish material differences. For example, the type of plastic can be identified by NIR, and different colors of glass or food can be distinguished by a color camera.

After image acquisition, the data is immediately transmitted to the image processing module. This module usually integrates artificial intelligence (AI) algorithms and machine learning models to perform high-speed identification, classification and defect judgment on each object. The processing system will set screening criteria, such as color mismatch, foreign matter, damage or size mismatch. Once the non-compliant material is identified, the system will instruct the spraying device to start in real time.

The spraying system usually uses a high-pressure airflow nozzle to complete precise spraying within milliseconds according to the signal sent by the processor, and remove the unqualified materials from the normal materials. Its response speed is extremely fast and suitable for large-flow continuous operation. In high-end equipment, tens of thousands of particles can be processed per second to ensure high efficiency and high precision.

The control system is responsible for the coordinated operation of various parts, recording production data, supporting remote monitoring, data export and parameter setting. Some equipment can also be connected to the production management system through the network to meet the needs of digital factories.

Optical Sorting Machine  realizes accurate identification and efficient sorting of materials through the coordinated work of optical recognition, image processing and intelligent spraying system, which not only improves product quality and resource utilization, but also significantly reduces labor costs. It is an indispensable intelligent device in modern sorting technology.

Optical Sorting Machine is an automated sorting equipment based on image recognition and intelligent analysis technology.
