Precision grind
Packing coffee into 8-gram capsules requires precision, so much
so that grinding for single-serve applications presents technical
challenges addressed by Neuhaus Neotec in its next-generation
Neogrind series machines.
Since production runs are long, operators must concern
themselves with machine efficiencies such as cooling rotors to
prevent variations in gap. Temperature also effects the coffee.
Cooler coffee is more brittle which causes more fines to be pro-
duced during grinding. Coffee at higher temperatures is mal-
leable, reducing the number of fines and increasing flow rate.
"Uniform particle distribution, even in the finest grinds,
as well as a high reproducibility and low-dust grinding are the
strong points of these machines," according to Neotec's Mi-
chael Ziemann, an engineer who helped develop the dual-speed
rollers and reduction gear design.
"The aim was not only to comply with legal standards for
energy-efficient motors, but to exceed them. With the IE-3 mo-
tors for the optional individually driven, continuously adjustable
rolls, Neogrind relies on particularly energy-efficient motors as-
suring a high capacity," he said.
Ziemann explained that temperature controls ensure the
temperature of each roll can be maintained (which requires
heating rolls at the beginning of the run and cooling as the run
progresses). A smooth-walled grinding chamber prevents prod-
uct adhesions and the grinding chamber is fully accessible in or-
der to facilitate cleaning. Like the other grinders of the Neuhaus
Neotec grinder family, the Neogrind can be easily customized
thanks to different configuration options.
Capacity varies with the roller length. A 200 mm roller pro-
duces 200 kilos per hour (espresso settings) and 650 kilos per
hour at filter coffee settings. A 400 mm roller produces 400 ki-
los per hour of espresso grind and up to 1,300 kilos per hour of
filter grind.
The Neogrind is specifically designed for coffee capsules
and pods and offers the highest accuracy in particle distribution,
closing a gap in the company's family of grinders that span a
range from laboratory to full-scale commercial grinders.
