About used Potato sorting machines

Today's market requires both seed and consumer potatoes to be of an outstanding and uniform quality. The use of a potato grading machine will considerably increase your revenue, as this will enable more of your potatoes to be marketed in a better-paying trade size.

Potatoes can be graded according to size using several types of potato grading machines: crate grading machines, hopper grading machines and step grading machines. All of these machines are based on more or less the same grading method.

Vibration sorting machines for potatoes

Potatoes can be sorted and graded very accurately and in a highly product-friendly way in a vibration grading machine. The potatoes are conveyed upwards at a diagonal angle and tipped over slightly at a forwards slant with every vibrating movement. The shock depth and direction of most of these grading machines can be easily adjusted. This enables you to direct the machine's movement in such a way that you will always have the right vibratory movement for not only various seed and consumer potato varieties, but also for onions and Brussels sprouts.

The rubber-lined sieves reduce all chances of damage to a minimum and will not fill as quickly as steel sieves. As the rubber lining can rotate around the steel, any chances of the products becoming trapped in the mesh will be reduced considerably.

Quality inspection by potato grading machines

Besides the actual process of sorting by size, grading the quality of the potatoes is also very important. You can be assured of delivering products of a uniform quality by using a roller inspection table to identify dirt and poor quality potatoes. Nowadays optical grading machines with cameras are also available for precision grading by quality.

Investing in a potato sorting machine
