Bühler launches new Arrius grinding solution for the milling industry
Bühler has unveiled a new age in milling
technology with the launch of Arrius, an
integrated grinding technology for milling
wheat, durum, rye, barley, corn and spelt.
The launch follows a rethink of the
traditional grinding methods that lie
at the heart of the milling process. By
redesigning each technology component,
Bühler has produced an integrated and
self-adjusting grinding system that
empowers millers with greater control
over the quality and consistency of their
product.
Arrius has an integrated drive and gearbox, resulting in energy cost savings of up to 10%
At the heart of the Arrius step change lie
the sensors in the feeding module and
the roller pack enabling control of the
product flow and grinding process. It
allows Arrius to automatically adjust to
the characteristics of the raw material.
Double-sided sensors in the new roller
pack allow millers to continuously measure
the grinding force of the rollers. This
feature also allows the miller to control the
grinding process closely and thus optimise
product characteristics for their specific
market.
Besides the particle size distribution,
starch damage is a parameter that can
be improved. According to Bühler, Arrius
allows millers to better control the grinding
process of the product and increase starch
damage by up to 10% if required. And on
energy, Arrius has also been designed with
an integrated drive and gearbox, resulting
in energy cost savings of up to 10%, the
company added.
Commenting on the new technology, Dan
Dye, CEO of Denver-based Ardent Mills,
who has been working as a development
partner with Bühler on the project, said:
