About kit Optical Color Sorter & Aerodynamic Grain Cleaner (6AS+ADS)

Pairing the METRA ADS grain cleaner with the METRA 6AS color sorter provides comprehensive, high-quality grain processing. The METRA ADS performs aerodynamic cleaning, removing large and small impurities to achieve up to 98% purity, enhancing germination and quality for seed use. In the next stage, the METRA 6AS uses artificial intelligence to accurately identify and eliminate defective grains, ensuring uniformity suitable for premium and food-grade markets.

This combination reduces waste, boosts profitability, and enhances overall product quality: the METRA ADS efficiently cleans grain from contaminants, while the METRA 6AS, powered by deep learning and remote control, automatically detects and removes damaged grains, ensuring high sorting precision.

Improved Performance
Metra 6AS+ADS kit

Superior separation - 68 injectors VS 64 — won't let a single impurity through.

With a 5400-pixel CCD camera, defects as small as 0.01mm² can be sorted.
Shadow-free LED lighting ensures precise detection and optimal sorting accuracy.
Wide-angle design, anti-corrosion, non-toxic and harmless aluminum alloy grain chutes.
High-speed electromagnetic levitated ejector. Durable and fast responding

Remote control capability via a mobile app, with a tablet operating system.

Precise Sorting with Artificial Intelligence. Automatically detects and removes defective grains through deep learning technology, enhancing product quality.
Remote Control via Mobile App Allows monitoring and adjustment of the sorter through a mobile app, facilitating remote management and technical support.

Careful processing of grain using a laminar
airstream, without damaging the grain

Changing from one commodity to the next takes as little as 5 minutes.
All dust and small particles are collected by the Cyclone Dust Collector for non-grain waste and are discharged through a channel into separate trays via the airstream
The machines are suitable for operation both indoors and outdoors

All machines come with special rubber
padding within the separation chamber.

30% lower electrical consumption. Lower electrical consumption vs like type separators
Reliability and engine protection. The frequency converter protects from voltage surges allowing the motor to start and stop smoothly
You receive 90% of grain which has the best value and can be sold for top dollar
Germinate and mature simultaneously which gives you up to 40% better yields
