Gentle and crop protective

The deep, soft bunker bags ensure a gentle crop handling and even unloading.

High efficiency with significantly reduced labor costs

The GRIMME PowerCombi impresses with its exact separation performance of up to 98 % and a throughput rate of up to 100 tons per hour. Furthermore, the PowerCombi can be conveniently operated by one person, which significantly reduces labor costs.

Mechanically height-adjustable rubber intake flap

The height of the rubber intake flap can be adjusted easily and without tools, so that a simple, perfect adaptation to different transport vehicles is possible.

Thoroughly cleaned

The centrifugal cleaning system Turbo Clean offers the possibility to remove sticky soil from the rollers. Turbo Clean is ideal for sticky, adhesive soils. By use of an automatic timer it can be activated without the need for manual intervention.

Capacity Control

A sensor which monitors the filling level of the receiving hopper regulates the optimum hopper floor speed at all times. In this way the entire storage line is used to its capacity without manual readjustment.

Powerful and gentle

For maximum crop protection with the highest separation performance, GRIMME has perfected the soft PU spiral rollers over the years. The soft spiral rollers have a high self-cleaning effect to achieve an optimal cleaning result without obstructions even under difficult, sticky conditions.

Long service life

The sturdy bunker floor chain ensures a long service life and minimal maintenance.

Optimum crop flow

The infinitely adjustable hopper floor speed enables an optimum crop flow 

Maintenance-free

The rollers are driven directly and without loss of power by one hydraulic motor each. The speed of each pair of rollers can be adjusted independently of each other. Furthermore, the groups of rollers are adjustable in distance to achieve the best results with different crop sizes.

Trouble-free operation

The Top Clean belt scrapers ensure that the belts run smoothly on heavy, sticky soils.

The storage line evolves into an assembled unit

Flow Control connects all machines that belong to one storing line to each other. The entire line can be stopped by each machine without delay or automatically stops itself in case of trouble. The entire storage line can be started at the push of a button in a programmed start-up sequence from any terminal. In order to avoid blockages, the machines start from the final discharge point of the storage line back to the receiving hopper with a programmable time offset. The minimal manual control effort allows the entire line to be operated by a single person, thus reducing the need for additional manpower. In conjunction with the automatic speed control of the hopper floor, called Capacity Control, a uniform crop flow in the entire storing line can be ensured under all conditions.

Comfortable operation

The individually configurable operator terminal VC 50 allows each user to adapt his own user-interface in that way, that he is able to make settings as quickly and conveniently as possible.

Infinitely adjustment

The speed of the roller-sets can be infinitely adjusted for optimum and particularly gentle crop cleaning. The infinitely variable spacing and inclination adjustment of the PU spiral rollers enables quick adaptation of the soil cleaning to varying soil and trash proportions. The intensity of cleaning can be adapted via levelling adjustment.

Gentle crop transfer

The minimal drop step enables gentle crop transfer from the hopper floor to the PU spiral rollers.

1st separator

The first separator consists of 19 adjustable PU spiral rollers that separate the potatoes from loose soil, break up clods and pre-grade the potatoes according to a defined size. The pre-grading of the harvested crop into different sizes is important to ensure maximum throughput of the following separators while at the same time being as gentle as possible to the crop.

Clod separator

For the pre-graded fraction of potatoes with a diameter of less than 45 mm, the unique double clod separator, type CLS II, enables a gentle and efficient separation of stones and clods. Two clod separators are arranged one downstream to the other for maximum separation accuracy.

Completely automatic

The portion of the harvested crop with a diameter larger than 45 mm is passed by the high-performance opto-electronic separator, type TOMRA 3A. The separating device scans each individual item so that clods, stones and other foreign material are effectively sorted out by means of ejection fingers. As the uniformity and size of the crop increases, the throughput of the separator also increases significantly.

Optionally, potatoes with excessive green colouring are detected by the electronic image processing and sorted out fully automatically.
