The Visar Sortop optical sorting machine is the latest, fully automatic electronic vegetable sorter ideal for high-quality optical grading and sorting of carrots and potatoes. The Visar optical grader can sort any batch of carrots or potatoes consistently and efficiently, completely removing the need for manual sorting.

Tong is proud to be the UK’s sole distributor of the Swiss Visar Sortop carrot and potato sorters. Due to the success of its original carrot sorter, Visar now offers its advanced optical sorting technology in two models. A highly accurate optical carrot sorter, and an intelligent optical potato sorter.

The 360 degree mirror system means that every carrot and potato is entirely analysed, at an impressive rate of 12 to 15 carrots per second. This is the only reliable means of detecting any defects, whilst grading and weighing the carrots with exceptional accuracy to the nearest millimetre and gram.



A highly accurate nozzle system blows compressed air following a calculated trajectory, based on each carrot or potato’s dimension and weight.


Crop is handled exceptionally gently with no drops. Soft-lined output areas ensure the highest quality crop with no damage or breakages.


The Visar Sortop is different from any other optical sorter on the market. It can sort your whole crop efficiently, automatically and without manual labour. Other sorters often require an extra manual sort, some need crop to be re-graded, and others don’t have a grading and weighing function. The Visar offers a completely automatic optical sorting solution.

The unique software of the Sortop sorter really sets it apart from other optical sorting systems on the market. The exclusive design intelligent controls allow the system to work as if you were sorting manually, but with greater capacity and consistency.

The Visar-exclusive auto-learning software progressively and automatically learns what defects are acceptable and not, removing the removes the need for tedious adjusting and programming. This results in a very intelligent optical sorting solution which allows you to literally pass any batch of carrots or potatoes through the machine without adjustment.
