Filling a biogas plant is faster and more efficient with the "Ruby 2000" beet pulper. The attachment takes care of picking up the beets, transporting and crushing them as well as feeding the biogas plant in just one operation: The sugar beets are crushed by a roller and fall directly into the pre-pit or the solids feeder. Stones in the beet mass cannot cause any damage to the device. With the Fliegl beet pulper, energy farmers work more easily and economically, because it eliminates the need for a separate shredder for sugar beet.
