YSTRAL GMBH MASCHINENBAU + PROCESSTECHNIK

The combination of different process steps in one machine provides you with great rationalisation potential: Production times are minimised, sub-processes are completely eliminated, production costs are reduced.The YSTRAL Conti-TDS is based on the same principle as the YSTRAL Inline Disperser. A special rotor-stator system generates a large negative pressure and absorbs powder, without dust formation and loss-free, directly into the liquid. The inducted powder is dispersed immediately and under high shear. Clean manufacturing process thanks to a dust and loss-free powder feed, even with powders that are difficult to wet, sticky or dusty Aspirating and dispersing of powders directly from silo (via buffer hopper), big bag, hopper, sack, barrel etc. Optimized result a better digestion, a higher effectiveness of the raw materials and a higher product quality.

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.

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.
