The Brabender DSR Loss-in-Weight single screw is capable of reliably and accurately metering bulk ingredients at low to medium feed rates. The feeder has the following main components: a free-standing mounting base/scale with a high-accuracy strain gauge load cell, a horizontal stirring agitator in the screw trough, and an extension hopper for ingredient storage. The screw feeder provides mass flow of ingredient and consistent screw filling since the stirring agitator prevents bridging and promotes ingredient flow into the screw. This all stainless-steel feeder is also available in a volumetric version.
