mixer
preparing
a
hydrocolloid
dispersion
in
water.
The
objective
is
to
disperse
the
solid
rapidly
to
avoid
agglomeration.
Once
dispersed,
the
particles
can
hydrate
quickly
and
evenly
without
forming
lumps.

High Flow
unit with
open shaft
in 200
litres
of water.
10kg of
flour
is added
to demonstrate
rapid
powder
dispersion.
Note how
the High
Flow impeller
increases
agitation
compared
with the
example
above,
but also
increases
aeration.

mixing
a slurry
of 3200cP
guar gum
in 8 litres
of water.
500g of
guar powder
is added
to the
water
slowly
to ensure
that lumps
or "fisheyes"
are developed.
The video
shows
how these
lumps
are rapidly
processed
away to
leave
a smooth
hydrated
paste
ready
for dilution.

mixing
a 6% (by
weight)
slurry
of sodium
alginate
powder
and water
similar
to the
guar gum
above.
The difference
here is
that all
of the
powder
is added
at once.
The first
clip shows
the powder
addition
and the
second
clip is
taken
20 seconds
later
as the
alginate
completes
its hydration.
No lumps
or dry
material
remain
in the
vessel.
