Innovative Mixing System: Intensive Mixer with Vortex Chamber
The latest development of Lipp Mischtechnik, the Vortex Chamber, is an efficient mixing system with outstanding homogenizing and disintegrating characteristics.
The Vortex Chamber is mounted laterally on the mixing vessel. Contrary to other built-in homogenizers no part of the system protrudes into the mixing vessel so that the surface of the vessel is wiped completely by the mixing paddles.
By the rotation of the rotor inside the Vortex Chamber product is sucked into the centre of the chamber. After being passed through the outer area of the Vortex Chamber with its toothed shear system the mass is thrown back into the product in the mixing vessel. The mixing tools permanently transport new product into the Vortex Chamber so that the whole product is passed through the shearing zone in a very short time.

The special geometry of the Vortex Chamber is capable of sucking in and disintegrating also larger pieces.
Although the chamber is a recess in the mixing vessel, during discharging of the machine the rotor of the Vortex Chamber removes the product completely with no residues left in the chamber.
By constantly exchanging the product inside the Vortex Chamber with the entire product inside the mixer the heating of the product stays low and temperature gradients are avoided.
For the confectionary industry the Vortex Chamber represents an improvement of the previously developed LIPP machines, especially for the processing of rework. It is extremely efficient for rework which holds particles of wafer, nuts and biscuits as well as for rework containing water such as bars with caramel filling.

The advantages of the new system lie especially in the improved disintegration of agglomerates and the further reduction of the particle size which leads to a faster and more complete drying of the product. To retrofit already existing mixers with the Vortex Chamber is easily possible without having to adapt the mixing mechanism of the relevant mixers. Further applications are for e.g. the perfect wetting of powders with liquids, reduced conching time (liquefaction of refiner flakes) or the production of fillings containing nuts and almonds which are disintegrated through shearing and then transformed into a paste. |
