The Optica S from Tolsma-Grisnich is an optical sorting solution designed to remove unwanted materials and quality defects before potatoes or other produce enter storage. It detects and automatically sorts out stones, clods, rot, Fusarium, major surface defects and foreign objects, helping ensure that only clean, valuable produce reaches the store.
Designed to start sorting during intake, the Optica S combines intelligent optical detection, smart size and product separation, robust machine construction and easy operation. By removing soil, stones, clods and unwanted produce before storage, the system helps reduce waste, improve product flow and make better use of valuable storage capacity.
The machine integrates directly into the intake line and can be connected to the receiving hopper. Its screen belt removes loose soil before optical sorting, creating a cleaner product flow and supporting accurate sorting results. The screen belt is also better suited to batches containing stones than a flat PVC belt, which can be damaged by sharp stones.
The Optica S combines multiple sorting functions in one solution. An intuitive touchscreen and unique setup assistant support operators when configuring the machine and make daily operation straightforward. All functionality is included, with no separate licence required to operate the machine.
With faster intake, reduced labour requirements and a more efficient product flow, the Optica S is designed to improve the complete storage process. Removing unwanted materials at the front end results in a cleaner batch entering storage, while the product-friendly intake line helps reduce product damage from intake through to storage.
