Simultaneous sorting by quality, size and shape

How Newtec specializes in potato size-sorting

In terms of size-sorting, we measure length, diameter and volume with our in-house developed high-speed cameras.

12 vibrating channel feeders ensure gentle and efficient separation of the potatoes as they enter the camera unit. From the infeed section, the potatoes are rotated through the camera unit on Newtec roller vibrators (international patent) for complete surface coverage.

Upon exiting the camera unit, the potatoes are smoothly and gently placed on the spinaflex unit for transportation to the specified outlet. Once reaching the outlet, the spinaflex is triggered by electro-magnetic impulses and the potato is delivered. It is in this section where potatoes are sorted according to pre-set sorting criteria.

Each outlet (ranging from 2-13) gently carries a specific class or classes of the sorted potatoes e.g. outlet 1 for rejects.

Choosing the best angle

Every single potato is assessed in the camera section. The extended camera section is equipped with 3 cameras that photograph each and every potato up to 45 times to capture precise data on size, shape and surface quality.

The design of our camera sections is adapted to potatoes. The potatoes are conveyed and led through the camera section on vibrating rollers - a unique and patented system which ensures that the potatoes are inspected from all angles because they rotate while they are propelled forward by gentle roller vibrations.

The machine is constructed with maximum efficiency in mind, combining high production throughput with a relatively small footprint.

We are proud to offer an efficient and space-saving machine that ensures a very thorough quality check and classification of every single crop before it is presented in the sales packaging.

From farm to fork

It is amazing how many criteria growers, manufacturers and consumers have when it comes to defining the best potato quality. There are grower’s demands for disease resistance, agronomic qualities and profitability as well as manufacturers’ demands for high-speed production, accuracy and consistency in quality. The large supermarket chains have on-going demands for better and more competitive products for their consumers in the different markets. Wishes for appearance, variety, taste, size, shape and quality varies from consumer to consumer, market to market.

Quality control begins prior to the crop being planted. The growers choose the most suitable fields for growing crop, agree on a fertilizing strategy and determine the planting density for the different varieties in order to optimize the yield.

The production manager inspects the fields during the growth season to check for virus, bacterial diseases, areas with water shortage or other conditions of importance for the quality.

When the potatoes have been harvested and stored, a sample of the raw material from the lot is taken. The sample is analyzed and the suitability of the lot is evaluated for export.

Newtec manufactures the machines for the type of potato that will work in your market and live up to your quality standards and pre-set classifications.
