Colour Sorters

Perry provide an optical Colour Sorter range which consists of cost effective, high capacity, machines featuring either the latest full colour RGB (Red, Green, Blue) technology or the more accurate Near Infrared technology. 

How it works

The products to be sorted drop by gravity on the chute and are inspected by a series of digital cameras that are able to recognise any defect in the product. Once the defect has been recognised, a blow of compressed air deflects it, bringing it to the waste collection area.

What makes these colour sorters so good?

These optical sorters are able to detect any defect in the inspected material, using digital cameras at high resolution able to distinguish 16 million colors and imperfections up to 0.09 mm. This is possible thanks to the full color and trichromatic technology, which allows the camera lenses to replicate the human eye’s ability to distinguish even the smallest shade of colour.

In addition the colour sorters cross recognise in size and colour. This double evaluation allows you to select the materials by limiting the processing waste as much as possible and, consequently, increasing the quality of the final product.

What capacity can they do?

The range has sorters from 1 chute through to 8 chutes with ~ 4-6tph capacity on wheat per chute.

The actual capacity is governed by the characteristics of the product and the level of contamination present.

Who’s the manufacturer?

The colour sorters are designed and manufactured by IST Technologies in Italy.  Just like Perrys they develop their product ranges in-house including the software so they can easily answer any queries.

The Perry team have invested in training up our technical support team in the UK in the operation of the IST colour sorters and also hold a stock of spare parts in their UK based factory so speedy support can be given.
