Distromix
DB25E 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.

Distromix
DB100F 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.

Distromix
DB100 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.

Distromix
DB100 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.
