LG Series AI Deep Learning Optical Sorter for Bean Processing

High-Precision Optical Sorting Machine with UHDR Technology

In modern bean processing plants, achieving high purity, consistent quality, and maximum yield requires more than traditional color sorting.
The LG Series AI Deep Learning Color Sorter, developed by Goldensorter is a next-generation belt-type optical sorting machine designed for complex bean sorting applications.

Powered by Deep Learning AI and UHDR (Ultra High Definition Recognition) technology, the LG Series delivers outstanding accuracy and efficiency for high-end bean processing.

Why Bean Sorting Needs AI Deep Learning

Beans such as fava beans, mung beans, soybeans, red beans, and mixed beans often contain defects caused by:

• Diseases, pests, and growing conditions

• Mechanical damage during harvesting and processing

• Mold and mildew during storage and transportation

• Mixed organic and inorganic impurities

Many of these defects show micro color differences, micro shape differences, or same-color impurities, which are extremely difficult to identify using conventional color sorters.

Optical Sorter with AI Deep Learning Sorting Technology

Our AI deep learning color sorter goes far beyond traditional RGB or simple shape recognition.

Key Advantages of Deep Learning Sorting:

• Multi-dimensional recognition: color, shape, size, texture, and surface patterns

• Self-learning algorithms trained on massive bean defect samples

• Accurate identification of subtle defects, such as:

  • Wrinkled skin

  • Hidden insect damage

  • Slight mold and early-stage mildew

  • Dark texture differences with the same color and shape

By simulating human visual judgment and continuously optimizing through data learning, the machine achieves stable and consistent sorting performance even with complex mixed materials.

The system is trained using a 20-billion-level self-collected open-source material database, which can be shared among users and continuously optimized for different bean varieties.

UHDR – Ultra High Definition Recognition

The LG Series adopts four-dimensional UHDR technology, achieving ultra-clear and ultra-precise identification of materials based on:

• Color

• Shape

• Texture

• Area, light, and shade

This multi-dimensional recognition allows the LG Series to easily solve sorting problems that traditional machines cannot handle.

Optional Infrared Sorting

With an optional high-end infrared configuration, the LG Series can effectively separate:

• Same-color foreign objects

• Organic and inorganic impurities

• Difficult-to-identify contaminants

This ensures ultimate product purity, making the LG Series ideal for premium and export-grade bean processing.
