Agitator technology stirs up drinks

The unique ability of the 'Visco-Jet' mixer is to safely blend heat-sensitive or fragile media of any viscosity while eliminating foaming by not producing bubbles and even giving big energy savings
The unique ability of the 'Visco-Jet' mixer's agitator technology to thoroughly and safely blend heat-sensitive or fragile media of any viscosity while eliminating foaming by not producing bubbles and even giving big energy savings has brought particular acclaim for this system in the drink and beverages industry Available in the UK from Orthos, Visco-Jet mixers have special cup-shaped agitators creating dynamic flow conditions at low operating speed that rapidly process virtually any aqueous medium without shear, heat or other damaging forces in containers of any size or shape

An added benefit is that container fill-level has no effect on complete mixing and homogenising performance, enabling plant to operate significantly more flexibly and cost-effectively.
But especially valued is the fact that a single universally deployable agitator design combines the advantages of product preservation with major cost-savings from reducing drive energy requirement and ending the user need for a wide selection of different stirrer types.
The 'secret' lies in the particular geometry of its cone-shaped stirrer mechanism.

Vibratory screen combine low cost and versatility
The Allgaier VRS vibratory screen, being shown at the RWM Show by Orthos, combines the lowest cost of operation with versatility and ease of use for wet and dry screening, dedusting and dewatering.
Through ingenious spatial and angular proportions, the agitator produces a prolonged flow and turbulence with low circumferential speeds, very gently and quickly guaranteeing an optimal homogenous mixing process.
Unlike conventional mixing devices, it does not produce turbulent flow at the edges, which eliminates shearing action.
Combined with the low rotational speed and short mixing time, this means media is not significantly heated and that optimal heat and cold transfer is guaranteed.
Foaming is avoided as air is not entrained during mixing.
Energy savings of up to 300% over conventional blade stirrers are provided by the Visco-Jet low-speed agitator design only needing low drive levels of 1.5 to 5kW regardless of media viscosity.
At the same time, low circumferential speeds of just 2 to 3m/sec, and even down to down to 0.35m/sec, also enable even perishable media to be processed safely.
Costs are further reduced, especially in the Drink and Bev industry, by only one agitator stage usually being needed for large container volumes.
For example, a single unit with three agitators and a 1.8m diameter is sufficient to fully homogenise the contents of a 3m diameter 15m3 capacity container.
Another major benefit of the Visco-Jet agitator system is that the stirring action spreads throughout the media and eliminates 'dead' points in all usual container geometries, including square.
All areas of the product are fully mixed without the need for additional inserts.
Various folding versions of the Visco-Jet that fit through the smallest holes and open out by centrifugal force allow use of this system in almost any container, even interchangeable transport units.
Agitators of virtually any diameter can be supplied for stationary applications.
