Mixing disperser YSTRAL Dispermix

Flexibility in chemical, food, cosmetic and pharmaceutical production. With only one machine, different products and product quantities can be produced with the most suitable tool. The tool shaft can be easily disconnected from the drive, e.g. for cleaning, while continuing to work with a second shaft. The tool shaft has a shaft bearing separate to the motor, which is driven via a plug connection. The possibility of adding a mobile lifting stand offers additional flexibility. Batch sizes from 5 to 1,000 l are covered by the X50, X100 and X200 series. The X100/X50 adapter enables an X100 to be used to produce batches ranging from 5 to 1,000 l. By simply exchanging the shafts, it is possible to conduct jet mixing, mixing dispersion, dispersion, powder aspiration and wetting. Maximum flexibility creates investment security - short set-up times and easy handling.

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.

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 high-performance dispersing machines work according to the rotor-stator principle with high shear gradients. The extreme fine distribution of solids (suspensions) and liquids (emulsions) in presented liquid media is achieved by the perfectly coordinated interaction of various comminution processes. The high-precision dispersion tools are individually adapted to the respective task. Robust rotor-stator tools with a narrow radial gap ensure high shear gradients. A strong dispersing effect is achieved by impact and high-frequency pressure-relief processes. Solid particles and/or droplets are reliably comminuted and homogeneously distributed. Different rotor-stator-pairs allow the adaptation to the corresponding application. No rotating vessel contents - no formation of droplets and no air ingress. No free-running shaft and no free-running dispersing tools. Batch dispersion directly in the vessel.
