Exchangeable shaft system YSTRAL Multipurpose

Intensive vertical mixing of the container ingredients in the micro and macro range. An additional downstream shear ring dispersion is not necessary. Due to optimal dispersion performance, high efficiency and easy handling of the mixing tools used, the Dispermix meets the high requirements of demanding production processes for the introduction of liquids or powders into liquid. Agglomerates are crushed and thus better wetting of the powder with the liquid. Different slot widths allow the adaptation to the corresponding application. The Dispermix head generates two differently directed liquid streams. A vertical partial flow is directed straight to the vessel bottom, where it is divided and circulates the entire vessel contents. A second partial stream is deflected horizontally in the Dispermix head and guided through the dispersion zone. Solid particles and/or droplets are reliably comminuted and homogeneously distributed.

The YSTRAL inline dispersing machines work according to the rotor-stator system. The dispersing machine is suitable for the production of suspensions, solutions and emulsions in the chemical, food, pharmaceutical and cosmetic industries. Due to the close radial gap between rotor and stator and the high circumferential speed of the rotating rotor, very large shear gradients are generated. The product enters the shear zone through the slots between the rotor teeth and leaves it again via the stator slots. Due to the multi-tooth configuration of rotor and stator, additional mechanical forces act on the product to be dispersed. The product is guided through a rotor-stator system. The liquid is highly accelerated by the inner rotor ring, is completely decelerated at the stator ring and then accelerated again to maximum speed via the next rotor ring. In this way, solid particles and/or droplets are effectively comminuted and homogeneously distributed.

The YSTRAL jet stream mixer fulfils all requirements for a complete and homogeneous mixing of the contents of a vessel. Effective micro- and macro-mixing of the entire contents of the vessel without the introduction of air. Complete mass transfer across all vessel levels due to vertical mixing. Up to 90% of the energy used is converted into vertical flow - no rotating vessel contents. Even heavy sediments are suspended by directed streams. Rotating parts are protected against unintentional intervention. With open tanks no tank fixing is necessary. A fast rotating rotor surrounded by a stator generates a downward directed guide jet which directs the liquid flow directly to the bottom of the container. At the bottom of the container, the stream splits and creates an upward flow on the outer wall. At the surface, the liquid flow is redirected towards the bottom of the tank.
