A distinction is made between basic mixing machines (“mixers”) and machines that fulfil other tasks at the same time as mixing, such as dispersers. “Mixers” work optimally according to the jetstream principle. In jetstream mixers, a fluid jet is steered to the bottom of the vessel during the mixing process. The fluid stream then divides here towards the vessel walls, where it then moves upwards. Once at the surface, it is sucked down by the mixing tool again (Jetstream Mixer, TDS-Induction Mixer, Multipurpose). In this way, optimum micro and macro-mixing can be guaranteed.
