Ribbon Blender
comprises of a U-shaped horizontal
trough and a specially designed
Double Helical Ribbon Agitator
rotating within. Ribbon Blenders
are based on a proven agitator
construction that provides a triple
mixing action ensuring fast, efficient
blending. The dimensions and configuration
of the ribbons are carefully balanced
to provide a movement of material
within the container that avoids
dead spots and gives rapid product
discharge.
An
alternate design is the paddle agitator.
The paddles are positioned to move
the material in opposing lateral
directions as well as radially.
The paddle design is generally employed
where friable materials are being
blended, and when batches as small
as 15% of the total capacity are
going to be mixed in the blender.
Design
Highlights
The outer ribbon displaces
the material from the ends
to the center while the inner
ribbon moves the material
from the center to the ends.
This counter-current action
results in homogenous blending.
The
ribbons rotate at approximately
70 - 100 meters per minute
and move the material both
radially and laterally to
ensure thorough blends in
short cycle times.
Triple
Mixing Action - The Key to Fast,
Efficient Blending
As the agitator
rotates, the material is tumbled
and carried radially around
the inside of the blender.
The pitch
of the outer ribbon moves
the material toward the discharge
opening.
The inner
ribbon which has an opposing
pitch moves the material away
from the discharge opening

Applications
Food
& Ingredients
Infant formula, cocoa mix,
instant salad dressing, cake
mixes, seasonings, flavorings,
gelatin ... the list of food
material in which our blender
can speed up mix times and
provide consistent uniformity,
goes on and on. All models
can be outfitted with cleaning
nozzles to aid in batch changes.
A variety of feed and discharge
arrangements are possible
to tailor to your needs.
Our blenders
provide the required uniformity
in shorter times which means
less dusting and breakage
of the ingredients that can
cause gastric ulcers in the
animals, and bridging of downstream
handling equipment. Additionally,
by using scrapers or drop
bottom discharge, the amount
of material left over between
batches is minimized, reducing
the opportunity for bacterial
growth.
Slurries
The action within ribbon blenders
is vigorous enough to homogenously
distribute liquid slurries.
Special high speed intensifiers
can be added to the bottom
to help break lumps that may
be present. Proper shaft seal
design is critical for handling
liquids. Shaft seal choices
include: mechanical, packing
glands and double mechanical.
