Whether you’re looking to fill 1 ton big bags or 1 ton boxes, the Tong UniFill gives you the flexibility to automatically fill both. Our range of ton box fillers have throughputs between 15 to 18 tonnes per hour.

Manufactured to offer the gentlest handling of the crop by safely holding crop in ‘pockets’ within the vertical filling crop elevators, the UniFill operates with a twin elevator system fed by one reversible crop conveyor. It fills boxes or big bags using one elevator at a time.


The UniFill automatically lowers the crop elevator into the big bag and as the bag fills, the elevator rises. When full, the reversible conveyor automatically reverses to feed the other vertical elevator and the process is repeated. When box filling, the conveyor traverses over the box allowing the vertical elevators to fill boxes evenly and gently.

The perfect solution for potatoes, carrots, parsnips and more.

A fixed-top model is available for filling big bags only, in which the crop conveyor is fixed for big bag filling, without the need to traverse.





Fitted with a heavy duty finger-flighted PVC belt, the UniFill big bag and box filling elevators gently receive crop from the cross conveyor. It holds crop in a ‘pocket’ formed by the belt’s fingers and an outer-fitted crop retaining belt. This ensures crop is held within the belts finger flights until it reaches the bottom of the elevator, guaranteeing minimal drop into the big bag or box.



Featuring fully automatic, microprocessor control via crop-sensing probes. The UniFill offers effective, gentle and even filling of big bag and boxes at the touch of a button.



Base on a simple yet effective design, the UniFill gives complete flexibility to growers and processors who regularly need to fill both big bags and boxes. Allowing quick and efficient fulfillment of contract demands.
