He continues: " On the nano side,
we have to push for higher vacuum
and higher temperatures, as many of
the nano-based products require mixing
technologies that can handle temperatures
of 350°C under full vacuum
for anywhere between 16 to 24 hours
of time in order for the molecules to
properly bond. On the natural side,
we are taking ingredients with various
densities and characteristics and,
without adding binders or artificial ingredients,
we have to find a way to
mix them quickly and efficiently.
" Not only do we need to accommodate
these different, but current
and relevant needs, but we must
keep in mind that when we go into
a facility, the processors usually have
an established footprint and process
in place, so tearing apart the existing
line to trade in a new mixer is not an
option. And, on top of that, we have
to keep efficiency and sustainability
top of mind. "
To meet these challenges, PerMix
developed a vertical paddle mixer
that operates as both a vacuum
mixer and a dryer. PAM Series vertical
paddle mixers (Figure 8) are
efficient and versatile blending machines
for batch mixing of free-flowing
powders, granules and pellets.
They allow the material particles and
ingredients to be mixed with minimal
mechanical and thermal stress,
which makes this type of mixer a
viable solution for fragile and heatsensitive
products.
Designed with a single shaft with
only one ribbon, the mixer can provide
multi-dimensional movement of
the materials. The ribbon inside the
mixing vessel moves the materials
upward from the bottom to the top.
The materials then drop by gravity
into the center, generating a counter
flow of the product particles. The
ribbon design ensures that the linear
speed of the particles are different
from one point to another, which results
in a turbulence flow field. During
operation, material particles and
heat are exchanged quickly, creating
a homogeneous product. In addition,
a high-speed chopper can be
added to provide intensive mixing
and/or lump breaking in applications
that require a liquid to be added to
powdery materials.
Thanks to recent innovations,
chemical processors are finding
ways to maximize the efficiency of
their mixing operations to help reduce
costs and increase sustainability
while providing new and better
chemical products.
