FlexWall®Plus Feeder

The FlexWall®Plus feeder is a universal, super compact screw-type metering feeder for virtually all kinds of bulk ingredients even with poorest flowability, featuring a trapezoid design and a paddle-massaged flexible polyurethane hopper. The feeder is available as a fully digital loss-in-weight feeder with a built-in digital load cell with two vibrating wires (“DigiMASS-2”) or as a volumetric metering feeder. The trapezoid design with divergent walls and the paddle principle ensuring full agitation of the entire ingredient compartment induce free mass flow and an optimum screw filling level without ingredient deterioration. To suit a variety of ingredients, the paddle agitation amplitudes can be varied. Single and twin screws are interchangeable. The unique design of the FlexWall®Plus feeder permits easy disassembly and cleaning. The polyurethane hopper features a lip, which seals to the upper edge of the stainless steel housing, and can easily be removed for wet cleaning. The super compact trapeziform design allows to configure up to 6 feeders or more around a central point of discharge in an extraordinarily space-saving manner. Suitable support structures can be supplied. Operation, service and maintenance do not require lateral feeder access so that the units can be placed closely side by side. For backward screw exchange from the rear feeder end a version can be supplied featuring a slewable motor. All gravimetric feeder versions are available as “intelligent” weigh feeders with integrated control and regulation electronics for control networks (field bus, Ethernet) connected either to Brabender touch screen operating units or directly to customers’ host or PLC systems.
