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.

Integrimix IBV60 fitted with High Flow impeller and vortex-eliminator shroud mixing dried whole egg powder into 150 litres of sugar/cream base.  The vortex-eliminator shroud reduces overall agitation and stops an aerating vortex from forming.  Minimising aeration is beneficial in many processes.
