With the launch of the PowerCombi, it is possible to use a receiving hopper with three highly efficient separation mechanisms to not only increase separation accuracy, but also to increase capacity up to 100 tonnes per hour. Up to 25% more efficient than the common systems. The first separator consists of the well known, infinitely adjustable packages of PU-spiral rollers. The first and the second package of rollers help to separate loose soil and to break up lumps of soil. The third roller package is used to pre-grade and to separate smaller potatoes and clods, which are conveyed to the second separator. The second separator is made of two specially designed rotating rollers, to aid further with separating smaller potatoes from the main crop. Oversized potatoes and other remaining impurities then pass through to the third separating device. An optical high performance separator, called TOMRA 3A. Clods, stones and foreign material in the crop flow are sorted out automatically by means of ejection fingers. Due to the high and exact separation, operating at up to 98% efficiency, far less staff are required to check for waste/bad crop and therefore this allows for considerably lower labour costs. The PowerCombi can easily be operated by a sole person.
