Abstract
A system for compacting organic material such as silage and inserting compacted material into an elongate plastic bag. A feed table delivers material to a rotor that propels and compacts material into an inlet of a tunnel. A proportional valve controlling the hydraulic motor of the feed table controls the rate of which the feed table delivers material. A speed sensor senses the speed of the rotor and transmits a signal to the control unit connected to the proportional valve of the feed table. Overfeeding of material to the rotor results in a reduction of the rotor speed. Such reduction is sensed and the feed table delivery rate adjusted accordingly to optimize filling of the bag.
