LEO-150D3 Color Sorter

The Anzai LEO-150D3 (commonly known as the Leo Sorter series) is a high-end, compact belt-type color sorter from Anzai Manufacturing Corporation of Japan.

Unlike traditional chute-type sorting machines that often scratch or break delicate materials, the LEO-150D3 uses a flat conveyor system to transport materials smoothly. This is a top-of-the-line optical sorting solution for fragile food products, irregularly shaped items, or recycled materials (plastics, electronic components) requiring absolute precision at the laboratory and small to medium-sized production facility scale.

Breakthrough technologies on the Anzai LEO-150D3

Exclusive “Human Eye” & “Highlight” recognition technology

The LEO-150D3 integrates the latest generation Full RGB digital camera for accurate visual simulation similar to the human eye.

Three-Attribute Color Analysis: Instead of simply identifying light and dark, the machine deeply analyzes color structure based on three mathematical parameters of the color spectrum: H (Hue), S (Saturation), and V (Brightness). This allows it to distinguish up to 16,770,000 different colors and detect even extremely microscopic color-changing particles.

Real-time Highlighting Feature: The LEO-150D3 automatically highlights defective areas of the material on the screen in real time. Operators simply touch the displayed defect point on the screen to initiate removal – a unique, intuitive, and easy operating experience.

Flat Conveyor Design Prevents Material Loss

100% Shape Protection: Materials remain stable on the conveyor belt sliding through the scanning chamber instead of falling freely or colliding with the trough walls. This completely eliminates the rate of cracking and scratching of product surfaces.

Ultra-Compact Size: The conveyor belt width of the LEO-150D3 has been refined to only 150 mm (half the width of the standard LEO-300 model), making it a mini sorting station that doesn’t take up much factory space.

Quick-Disassembly & Waterproof Design: The conveyor belt has a smart tool-free disassembly mechanism, allowing for cleaning and batch switching in minutes.

Twin LED and Infrared Lighting (D3 Configuration)

The D3 designation represents the highest-end Full Color segment of the machine. The machine is equipped with a durable Twin LED (Top & Bottom) lighting system combined with a near-infrared (NIR) LED system. This combination allows the machine to easily separate foreign objects of the same color but different materials (e.g., transparent plastic pieces mixed in with food, stones, glass).

SY Ejector & AI System

New generation SY ejector system: Extremely fast firing response, concentrated pin-point airflow for precise removal of foreign objects without displacing adjacent finished product particles.

Integrated AI system: The machine uses self-learning AI algorithms to analyze data and automatically suggest the optimal sorting filter based on the input material sample.

Intelligent management: 8-inch touchscreen displays ejector firing frequency graphs, stores error history and operation logs directly via USB for optimized quality management.

Diverse Practical Applications of LEO-150D3

Thanks to its flat conveyor belt principle that doesn’t destroy the material structure, the LEO-150D3 excellently solves problems that vertical chute machines cannot handle:

Agricultural Products & Premium Foods: Fragile or oily nuts such as cashews, almonds, walnuts, various beans (red beans, soybeans, green beans), buckwheat, raisins, dried garlic slices, and especially potato chips and baked rice cakes.

Recycling Plastics & Electronic Components: Color sorting of shredded plastic granules (PET, PP, HDPE flakes), separation of metal fragments, faulty circuit boards, or sorting of industrial scrap.
