Red Mill Snack Foods have helped increase their production and ensure

the high quality of their products by installing Watson-Marlow 700 series

pumps to meter flavourings. Unfailing, repeatable accuracy (± 0.5%)

and ease of cleaning, added to reliability and low maintenance, are the

keys to the long term success of Watson-Marlow peristaltic pumps at

the Red Mill production facility. The pumps handle some thirty different

flavourings used in the extensive range of extruded maize snacks.

The low shear pumping action and the ability to totally enclose the

pumped media within the tube, ensures optimum levels of hygiene and

product integrity. The ability to sustain volumetric accuracy ensures that

consistent dosage of the flavouring is maintained at all times. At the end

of a shift the pumps are reversed to scavenge the lines and return

residual product to the mixing kettles, so saving waste.
