Special "Optoelectronic Sorting"

The sorting of brushed, unwashed potatoes will be demonstrated live in the Special “Optoelectronic Sorting”. Will it be possible to replace complex manual work by technology in future? Be there when the potatoes roll and drop into the designated boxes. The machines will be running several times a day.

How will the market for sorting machines develop in the near to mid-term future?


The way of buying food is moving, and big distributors are already following this movement as new actors like Amazon are coming. Mid-size and even small cooperatives will also have to provide a best sorting quality at an affordable price and modern sorting technology can help for this. Traceability of is an important point: Some of the consumers are already asking where the vegetables have been cultivated. This could even go further with data collecting during the whole production process. The market has the possibility to have a quality level between low price products and extra quality is a win-win solution as the distributors can sell more products at their correct price.


Which are some of the main challenges associated with the sorting segment and what is Visar Sorting’s approach to overcoming them?


The consumers requirements are increasing day after day (price, freshness, quality, traceability) and that comes back on distributors, and so on packagers. They need a maximum efficiency as the freshness flow cannot be depreciated. The reliability of our machine that can sometimes work 24/7 is our main goal, and as a swiss company we are proudly attached to defend our reputation of quality in equipment and service. We work on increasing capacity of our machine with no compromising on quality and reliability.


What are Visar Sorting’s latest innovation targeting potato sorting equipment? 

The “Visar Sortop Potatoes” can sort washed potatoes, unwashed potatoes (seed potatoes for example) and peeled potatoes. It has a unique optical configuration combining full 360° viewing in one shot and high definition (0.16 mm2) with infrared signal camera. This allows to analyze shape, green surfaces, strokes, dark spots, scab, silver scab, cracks, worms holes with the best accuracy. Each criterion has three quality levels. A product that doesn’t reach the lowest level on one of the criterion goes to waste.The machine can sort about 2,5 t/h depending diameter of products. 



Due to the high-resolution infrared view with additional color vision, the smallest damage such as worm holes can be detected. All detected damages are accurately displayed on the screen.

The principle is based on artificial intelligence, which allows the subjective assessment of quality, shape and appearance of each potato. In this way a simple selection of three quality levels -and additionally waste- is possible.
