Series HKRF
Rotoflow Feeder
The rotoflow feeder meters flour evenly into the bagging scale or the pneumatic line and prevents bridging in the bin.

Flour tends to bridge in a bin and interrupt the flow. The rotoflow feeder carries a rotating shaft across the full section under the bin, breaking that bridge and drawing product evenly from the whole cross-section.
Even feeding directly affects the weighing accuracy of the bagging scale and the stability of the pneumatic line. Because the shaft turns slowly the flour is not aerated and its density stays constant.
Separate body widths for flour and bran, motor ratings and dimensions are given in the model table. End bearings are lubricated from outside.
Key features
- Rotating shaft that prevents bridging under the bin
- Even draw across the whole cross-section
- Low speed that does not aerate the flour
- Separate body widths for flour and bran
- End bearings lubricated from outside
Applications
- Feeding bagging scales
- Feeding pneumatic lines
- Under flour and bran bins
How it works
Working principle
Packaging fills 25–50 kg bags with repeatable accuracy at the end of the line, ready for palletising and dispatch.
- 1The carousel turns the filling spouts past a single operator, who hangs an empty bag on each.
- 2Each spout fills its bag in a coarse stream and then a fine stream for an exact weight.
- 3A double weighing scale checks every bag against the set point.
- 4Filled bags drop onto the take-away conveyor towards closing and palletising.
