In many applications simple mixing is not sufficient to get a product with a homogeneous quality.
This is especially true when powders that tend to form agglomerates or gels (CMC, Xanthan, Carbopol, Locust bean gum, Alginate etc.) have to be mixed into liquids. This is the point where the capability of a mixing tool has to show its effect.
Large area mixing does not help even when using a Jetstream mixer as the moment when the agglomerates leave the mixing head the turbulence in the liquid is not strong enough to destroy the lumps or agglomerates, and they float with the turbulence only.
The best example is the treatment of the above mentioned powders. Conventional stirrers require a lot of energy and time to dissolve or break the lumps as the powder immediately forms a layer of gel at the surface and further powders then float at the surface level.
The stirring element can [after some time], remove the layer but the small lumps, some less than a millimetre, can’t be broken down.
Very often an additional processing step with a dispersing machine or a high pressure homogeniser is required.
Especially for such applications a mixing and dispersing tool has been developed that offers a perfect compromise between large volume mixing (macro mixing) and required dispersing effect (micro mixing).
The part of the mixing head that is responsible for the large volume mixing shows a similarity with the head of a Jetstream mixer, while the part for the dispersing looks like a batch rotor-stator high shear system.
The performance of a DISPERMIX is in-between the performance of a Jetstream mixer and the shear capability of a batch disperser.
Perfect applications are the dissolving of CMC powder; Carbopol; Plastisol colouring; Polymer solutions; cold emulsifying of aroma oil; production and suspending of juice concentrates; ice cream pre-mix; pre-Emulsifying of soft margarine; dessert-sauces of all kind; chocolate, and milk pudding; and pre-mixes, especially when hydro colloids have to be mixed into a liquid.
