Screw Feeder DDSR40B 2.0 (AC) Volumetric and gravimetric General Information The DDSR40B feeder is ideal for difficult flowing, sticky, bulk ingredients that tend to compact or form bridges while it is at rest in the storage hopper. The feeder has the following main components: A stainless steel screw trough with inspection opening, a modular gear block, a two-part agitator in the screw trough, a three-phase motor to drive the agitator, a double screw, a three-phase motor for driving the screw, a screw tube, an extension hopper with a capacity of 100 dm³ (3.5 cuft) or 200 dm³ (7.1 cuft) for storing bulk material. For caking bulk solids, which tend to solidify and bridge when at rest in the hopper, a 180 dm³ (6.4 cuft) hopper with an agitator (AR) can be used. The horizontal agitator works to consistently fill the screw and prevents hopper bridging while providing mass flow. This results in optimal feeder accuracy and control. In addition, the twin screw is characterized by a particularly large feed area which, in conjunction with a steep-walled hopper, ensures reliable mass flow even with bulk materials that normally require an additional agitator in the hopper. The DDSR40B is easily disassembled for wet or dry cleaning. All service is from the front or back. The gravimetric version includes the weighing systems DLS6 and MD6 featuring a high resolution digital load cell with serial data transmission as well as MS6 with strain gauge load cell with advanced filtering technology. The unit conforms to CE directives.

Depending on the flow characteristics the screw filling level may decrease to 50%. Further limitations have to be considered for gravimetric feeding, as max. speed should be reduced to allow for bulk density variations.
