Cleaning and separation systems
All belts and rollers are hydraulically driven, therefore their speed can be adjusted steplessly.The ROPA Keiler has large cleaning components with maximum cleaning area for gentle and efficient cleaning. The ROPA Keiler is particularly efficient for harvesting on heavy soils and/or during bad weather.
Overview of models

KEILER 2 RK22 CLASSIC
The Keiler 2 Classic with 2 pintle belts is perfect for high performance and gentle separation of crop and impurities on loose soils.
Twin-Clean
In the Keiler 2 RK22, the first lifting chain or sieve conveyor is hydraulically reversible.
With Twin Clean, ROPA introduces a new optional split of the first sieve conveyor into a lifting chain and a sieve conveyor. This configuration allows both belts to be operated with different pitches and speeds. It is useful for both quick replacement of the lifting chain as well as adjustment to different harvesting conditions or when switching to onions. The optimized sieve channel is designed in such a way that the Twin Clean can also be easily retrofitted later. Switching between Twin Clean and the sieve conveyor can be performed quickly and easily during the season. The height difference of the conveyors additionally improves the sieving performance.
Hydraulic drives:
1. Shaker.
2. Sieve conveyor
3. Lifter chain
Trash management
Improved leaf chain routing and leaf retainer springs
The interaction between the leaf chain and the arrangement of the retention springs has been adapted for optimised leaf removal and improved separation as well as reducing potato losses at the same time. The pull-off rods can be easily installed if required.

Dirt discharge conveyor
The leaf chain, which can be selected in different pitches, separates leaf residues from the potato flow and conveys them to the rear of the machine.
Wizard systems
- Optimum conveyor regulation with no additional effort due to the combination of driving speed-dependent and load-dependent control
- When the driving speed changes, speeds of sieve conveyors 1 and 2 as well as pintle belt 1 are adjusted proportionally to the driving speed
- In case of temporary load peaks, the load-dependent control temporarily increases the speed of sieve conveyor 2 and pintle belt 1 in order to avoid reduced cleaning performance or blockages
- For particularly efficient and gentle harvesting with the automatic conveyor regulation, the minimum and maximum speed can be set individually
- Saving of up to 6 lifting programmes and manual conveyor control possible for cleaning and service purposes
ROPA potato crusher
The ROPA potato crusher with integrated stone protection is a sustainable, herbicide-free and resource-saving method for reducing regrowth of potatoes in the successor crop. The potato crusher squashes and grinds the tubers, sorted out via discharge chutes and a trash track. This promotes rotting and prevents germination of potatoes in the following year.
FUNCTION AND BENEFITS OF THE ROPA POTATO CRUSHER

1. Hardox shredding knife on one crusher wheel
Small pieces are shredded from large potatoes, until they are caught by the crusher wheels, crushed and pressed through the gap
Large tubers are shredded to small pieces, caught and also crushed
2. Hydraulic drive for rubber wheels
The friction effect of the different rotational speeds of the wheels reinforces the shredding effect during crushing
The rotary speed can be adjusted by a volume regulator
3. Mechanical stone and foreign object protection pre-tensioned by spiral springs - for uninterrupted harvesting

1. Volume regulator for speed adjustment
2. Very quiet operation
- Crusher wheels not in direct contact
- The distance between the crusher rollers can be adjusted by a spindle
Rubber tyres as crusher rollers
- Low wear and tear
- Low force required
- Quiet operation with low vibration, even with high proportion of stones in the soil
- Air pressure in wheels can be adjusted
The potato crusher consists of two pneumatic tyres rotating at different speeds
Sorting platform
Comfortable sorting platform
The large-dimensioned sorting platform provides enough place for up to 5 operators. Thanks to the pull-out sorting stand the platform can be extended by 300 mm. The trash conveyor, which can be independently adjusted in speed, transports the admixtures sorted out by the UFK to the right discharge chute. The discharge chutes with rounded edges reliably guide the sorted out admixtures onto the trash discharge conveyor, which can guide the admixtures back into the sieve channel 2 if required.

Working platform, 300 mm extendable - immense working area allows freedom of movement
Customised upholstered parts, a hand-washing tank and drink holders provide further comfort at the sorting platform. A folding ladder with damping and pinch protection provides easy access to the platform.
