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.

TDS Induction Mixers draw powder, liquids or gases below their level into liquids and at the same time homogenise the contents of the container. The vacuum required for induction is generated in the mixing head. The machine is installed in the container from above by means of a flange or traverse. Alternatively, the TDS Induction Mixer can work on a lifting frame. The powder is inducted from the container and introduced under the fluid level by mixing it immediately and wetting. The mixing head generates the required negative pressure. Dust loads are prevented during the addition of powder by direct induction from the bag. Effective micro and macro mixing of the complete container contents with simultaneous addition of powder. Immediate wetting under fluid level. Complete mass transfer and homogeneity across all container levels via the jetstream mixing principle. In addition, liquids and gases can be inducted.

The DaiTec offers all the advantages of the Conti-TDS technology and is specially tailored to the requirements of the milk processing and food industry. It is characterized by its 3A certified design and a powder feeding table with integrated hopper at an ergonomic working height. It is connected directly to existing containers and is ready for operation after a few simple steps. Due to its powerful suction vacuum, the machine can suck in and disperse directly from the powder container by means of a suction pipe in addition to suction from the hopper. It ensures dust-free container emptying, powder transport, powder introduction, powder wetting and dispersion. Agglomerate-free, highly concentrated, homogeneous and very stable dispersions due to the use of high shear energy and the wetting/dispersing of powders under vacuum. Excellent emulsifying properties - narrow spectrum of droplet size even without high pressure homogenizer. 3A-certified design

The latest generation of multifunctional YSTRAL PiloTec process equipment offers you the opportunity to use established production processes on a laboratory scale. Thanks to Conti-TDS technology, powder can be inducted, wetted and dispersed under vacuum, dust-free and in a single operation. Easy-to-use swappable tools enable operation using the innovative Multi-Z or Z-Inline process with high-precision multi-stage shear ring systems. Established procedures and a specific energy input independent of the batch size guarantee excellent and consistent results. These can be easily transferred to production scale - a safe scale-up to ystral plant construction. The modular design enables extension to the PiloTec-Plant process plant with ystral mixing technology, systems for handling powders and liquids, measuring technology and sensors, lifting stands as well as other modular components.

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.

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.
