Cleaning and separation systems
All belts and rollers are hydraulically driven and therefore speeds can be steplessly adjusted.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.
Model overview

KEILER 2 RK22 CLASSIC
The Keiler 2 Classic with 2 pintle belts is perfect for efficient and gentle separation of crop and impurities on light, loose soils.
Twin-clean
In the Keiler 2 RK22, the first lifting chain or sieve conveyor is hydraulically reversible
Twin-Clean is the new optional split of the first sieve conveyor into a lifting chain and a sieve conveyor. Both conveyors can be operated with different pitches and at different speeds. It is as useful for quick replacement of the first lifting chain as for adjustment to different harvesting conditions or when switching to onions. The sieve channel is designed in such a way that the Twin-Clean can also be retrofitted later. The height difference of the conveyors increases 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 optimized 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
- Optimal conveyor regulation with no additional effort due to the combination of driving speed-dependent and load-dependent control
- When the driving speed changes, the speeds of sieve conveyor 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
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 press crushes and grinds the tubers sorted out via the discharge chutes and trash track. This promotes decay and consistently prevents the germination of tubers the next year.
FUNCTION AND BENEFITS OF THE ROPA POTATO CRUSHER

1. Shredding blade of Hardox on a crushing tire
Small pieces are beat off large potatoes until these are caught, crushed, and pressed by the pressing rollers
Large clods are broken up into small pieces, caught, and also crushed
2. Hydraulic drive of the rubber wheels
The friction effect of the different rotational speeds of the wheels reinforces the shredding during pressing
The speeds can be adjusted variably with a quantity controller
3. Mechanical guard against stones and foreign bodies via spiral springs for pre-tensioning - for uninterrupted harvesting

1. Quantity controller for speed adjustment
2. Very quiet operation
- No direct contact of the pressing rollers
- The distance between the pressing rollers can be set variably with a spindle
Rubber tires as pressing rollers
- Low wear
- Little application of force
- Quiet and low-vibration running, even with more stones in the soil
- Variably adjustable air pressure in the wheels
The potato crusher consists of two pneumatic wheels driven 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 - large working area allows greater freedom of movement
Customized 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.
