Mixing is a crucial part of the
anaerobic digestion process
and Huntingdon-based
System Mix, which markets
the Rotamix System incorp –
orating the Vaughan chopper
pump, is an established
supplier of digester mixing
systems at numerous
installations across the UK.

Director, Andy Parr, says:
“It is crucial to the AD process
that suitable pre-conditioning
of solids is carried-out prior to
digestion and our system has
protection technology mean
significantly reduced
downtime and savings on
consumables, says the
company. A tough stainlesssteel
nozzle guard protects the
printhead from possible
damage, caused by impact
with the boxes on the line,
while remaining close enough
to the packaging to ensure
good print quality.

been proven to be one of the
most effective in achieving this.

“The Vaughan pump
prevents re-accumulation of
fibrous and fatty material in the
digester and this means that
material continues to pass
through the nozzles. This in
turn ensures that digestate is
adequately conditioned and
actually benefits all postdigestion
equipment.”
He concludes: “As many
AD operators are now
looking to maximise the
sustainable credentials of
their plant and equipment
even further, we are confident
that the benefits of our
mixing systems are becoming
even more important.”
