Pellet Sorter II

Hiroshima, Japan; June 19, 2025 - Satake launched an optical sorter exclusively developed for plastic pellets, Pellet Sorter II.

Pellet Sorter II is a specialized optical sorter to remove defective products such as speck damage and discolorations mixed in plastic pellet raw materials, with a high throughput of up to 3.0t/h.
Fed by a 600mm wide belt conveyor, product is scanned by front and rear 4K high-definition cameras. Using Satake Intelligent Software, accept and reject products are instantly identified and reject products are efficiently removed by the high-speed Piezo ejector valves.
In 2009, Satake developed the first Pellet Sorter, an optical sorter capable of sorting plastic pellets, which achieved results not previously possible within the industry. Committed to continuous development of new technology, Satake has not rested and has been working on the development of a new optical sorter with the aim of further improving the defective product sorting ratio.
The new Pellet Sorter II was redesigned to use high intensity LED lighting and now has the ability to sort transparent or opaque pellets with a single unit.
In addition, the all new 4k cameras, combined with advanced Japanese designed high-speed signal processors and Satake Intelligent Software give the high resolution to achieve precision targeted separation of discolored and defective pellets and can detect 0.1mm speck damage. The adoption of patented Piezo valves enables removal of defective pellets with pinpoint accuracy to increase the purity of the plastic pellets while minimizing product loss.
