TOMRA 3A

Boasting the highest capacity on the market, the TOMRA 3A is the most reliable and cost-effective optical sorter available for growers. Built to last, it is a durable, powerful, and highly efficient labor-saving solution specifically developed to provide unrivaled foreign material removal and exceed harvest demands. The machine is easy to use, simple to maintain, and its smooth install makes for an easy fit into the harvest cleaning and grading line, or out-of-storage sorting.

SOPHISTICATED TECHNOLOGY.
HIGH PERFORMANCE.


The TOMRA 3A utilizes NIR (Near Infra-Red) multi-spectral sensors for an unobstructed assessment of every object, seamlessly identifying between a good product and foreign material. Color sensors also enable the detection of unwanted green potatoes. Positioned at the end of the conveyor belt, intelligent finger ejectors achieve superior foreign material and green potato removal with minimum loss of good product.

The strategic combination of multi-spectral pulsed LED technology, high-resolution cameras, and TOMRA analysis software ensures the accurate and consistent removal of stones, soil clods, rocks, wood, bone, plastic, glass, metal, and rubber.

Enclosed in a fully sealed box, the camera is tolerant of most environmental conditions such as rain, wind, dust, and heat, and the optical system has no moving parts, making the TOMRA 3A the most mobile, dependable, and stable sorter available.

Working Principle

The produce is spread uniformly onto the infeed belt and scanned in-flight by a full-width NIR and color vision in the inspection zone. A few milliseconds later, the foreign material is rejected by intelligent finger ejectors, positioned off the end of the conveyor belt, while the good produce is conveyed away by the supplied accept take away conveyor.
