Handling equipment - Receiving hopper | PowerCombi

Process up to 100 tons crop per hour with a maximum separation accuracy

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.

Gentle soil cleaning and pre-grading

Mechanical separation of loose soil, breaking up lumps of soil as well as pre-grading of smaller potatoes and cluds by use of GRIMME spiral rollers, made of polyurethane.

Gently separation of small potatoes from other trash

Two clod separators (CLS II) are separating small potatoes in a very gentle way
from other trash

The opto-electronic high performance separator TOMRA 3A

Clods, stones and foreign material are sorted out by means of ejection fingers.

Consistently high and precise separation performance of up to 98 %.

Far less staff are required to check for waste products and therefore this allows for considerably lower labour costs.

Control Systems


  • Precise separation performance of up to 98 %
  • Throughput up to 100 tons per hour
  • Conveniently operated by one person, thus labour costs can be significantly reduced
  • Gentle intake due to soft bags
  • Excellent emptying due to deep bags with active sealing
  • Durable due to large exterior rollers of the hopper floor chain
  • Optimum crop flow due to infinitely variable hopper floor speed
  • The gooseneck-shaped top end of the hopper ensures an even crop flow and discharge.
  • Gentle crop discharge from the hopper floor onto the spiral coils
  • Gentle soil cleaning and pre-grading with PU spiral coils
  • For quick adaptation to varying soil and amount of trash, as well as different sizes for pre-grading, the distance and inclination adjustment of the PU spiral rollers can be infinitely adjusted.
  • Ergonomically designed control platform
  • Maintenance free direct drives
  • Comfortable operation via operator terminal, type VC 50
