Inlet With Shaker Feeder (1)


Optimal feed over the full width of the cleaner is achieved with a shaker feeder. The shaker feeder is designed to handle all kinds of grain and seed through a gentle and controlled feeding. The feeding rate is controlled through a stepless speed adjustment, ensuring the required capacity for any application.


Pre- & After-Suction (2)

All Cimbria cleaners are equipped with a two-pass air separation system. The pre-suction is designed to remove dust and light foreign material at the inlet of the machine to reduce the amount of dust and fines inside the machine. This ensures a nice and even flow of product on the screens. The after-suction is designed to collect remaining husk and fines in the clean grain at the final outlet of the cleaner.


Flow (3)

Cimbria Delta cleaners are designed with a flexible flow system which offers the operator the possibility of using the optimum flow for a specific application. With easy changeable outlets and dividers the operator can choose between up to 16 different flow options on specific models. The optimum flow ensures maximum capacity and quality.



Screens (4)

The Cimbria screens are designed for highest possible efficiency and are effectively kept clean by rubber balls in special designed ball boxes. A high percentage of open area ensures maximum capacity in the machine.




Screen Shoes (5)

The screens shoes are made in coated marine plywood to ensure a long lifetime. With its strong and flexible structure, this material is extremely resistant against the constant movement in the machine. Wear areas inside the screen shoes are protected by easy replaceable plates in hardened steel.



Eccentric System (6)

The eccentric system is designed to drive the screen shoes and create a gentle flow of product through the machine. The weight of each screen shoe is optimized to ensure a wellbalanced and smooth motion. Supplied as standard with flywheel to recapture the force created by the movement of the screens shoes and reduce the power consumption.


Electronic Control System (7)

Cimbria fine cleaners are supplied with an electronic control system. The system consists of a control panel which operates actuators and motors with integrated frequency control. The actuators operate numerous air gates inside the machine, and with digital adjustment settings ranging from 0-100, the accuracy in the settings are very high.




Airlifting System (8)

The airlifting system consist of the airlifting unit providing a positive air flow from below the product and the negative air from the after-suction above. The unit is equipped with two staggered fans which ensures a homogenous air flow through the product on the final air screen. This combined with the electronic control system provides the most precise air separation adjustments on the market.


operator safety

Operator safety is our highest priority. The Cimbria cleaners are designed with covers to protect the operator from all moving parts. Samples from each outlet of the machine can be obtained with a special designed sample takers to ensure a user friendly and safe operation.
