YSTRAL Conti-TDS - No. 1 in powder wetting
Induction of powder, wetting and dispersing – with the YSTRAL Conti-TDS Dust- and loss-free powder container emptying, powder transporting and then wetting and dispersing down to a complete des-agglomeration are realised within a single machine – the YSTRAL Conti-TDS. Powders are not only wetted but dispersed into a liquid under vacuum. The formation of agglomerates is avoided. Higher efficiency incorporation of the raw materials and a better quality of the products are the natural result. The combination of processing steps in one machine results in an enormous potential for process rationalising. The essential advantages: • Production times are minimised • Partial processing steps are completely eliminated • Cost of production is reduced • Clean process due to dust- and loss-free powder induction, even for difficult to wet, sticky or dusty powders • Induction and dispersing of powders directly from silo (with intermediate buffer), Big Bag, hopper, sack, barrel, etc. • No adhesion to the vessel or installed components • Fast and reproducible adjustment of the products due to an immediate and complete incorporation of the raw materials • No induction of false air – powder transportation under vacuum in the dense phase
Simultaneous Mixing and Dispersing - DISPERMIX
In many applications simple mixing is not sufficient to get a product with a homogeneous quality. This is especially true when powders that tend to form agglomerates or gels (CMC, Xanthan, Carbopol, Locust bean gum, Alginate etc.) have to be mixed into liquids. This is the point where the capability of a mixing tool has to show its effect. Large area mixing does not help even when using a Jetstream mixer as the moment when the agglomerates leave the mixing head the turbulence in the liquid is not strong enough to destroy the lumps or agglomerates, and they float with the turbulence only. The best example is the treatment of the above mentioned powders. Conventional stirrers require a lot of energy and time to dissolve or break the lumps as the powder immediately forms a layer of gel at the surface and further powders then float at the surface level. The stirring element can [after some time], remove the layer but the small lumps, some less than a millimetre, can’t be broken down. Very often an additional processing step with a dispersing machine or a high pressure homogeniser is required. Especially for such applications a mixing and dispersing tool has been developed that offers a perfect compromise between large volume mixing (macro mixing) and required dispersing effect (micro mixing). The part of the mixing head that is responsible for the large volume mixing shows a similarity with the head of a Jetstream mixer, while the part for the dispersing looks like a batch rotor-stator high shear system. The performance of a DISPERMIX is in-between the performance of a Jetstream mixer and the shear capability of a batch disperser. Perfect applications are the dissolving of CMC powder; Carbopol; Plastisol colouring; Polymer solutions; cold emulsifying of aroma oil; production and suspending of juice concentrates; ice cream pre-mix; pre-Emulsifying of soft margarine; dessert-sauces of all kind; chocolate, and milk pudding; and pre-mixes, especially when hydro colloids have to be mixed into a liquid.
PiloTec - ystral in laboratory and pilot plant scale
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.
YSTRAL Jetstream Mixer - Constant product quality during mixing
The predominant mixing principle An effective micro and macro mixing is mandatory to achieve a consistent quality of a product in a variety of applications. The YSTRAL Jetstream Mixer fulfils all the requirements that are necessary for a completely and homogeneous mixture in a vessel. Therefore, economy, optimised mixing efficiency and simple handling are not compromised. The essential advantages: • Effective micro and macro mixing of the complete contents in the vessel without air induction • Complete material exchange over all the levels due to a vertical mixing effect • The applied energy is converted up to 90% in a vertical stream – no rotation of the contents in the vessel • Even heavy sediments are suspended by the directed stream • No free running shaft and mixing tools • No Vortex is formed, no air is introduced • Installation to the vessel from top, bottom, side or mounted on a moveable lift • For open vessels, no special fixing devices are required
YSTRAL Multipurpose X50/X100/X200 - flexibility is the key
Multi-functional by exchangeable shafts and Tools The advantage of the YSTRAL Multipurpose-Elements is given by the modular set-up: exchangeable shafts and exchangeable mixing and dispersing tools. Up to now this was known primarly in the laboratory sector. With the YSTRAL Multipurpose this advantage is also applied for the production equipment. With only one machine a variety of products and volumes may be treated with the most suitable tool. For the highest demands in hygienic fields of application, all connections are sealed according to the GMP guidelines. Numerous variants for drives and lifting frames complete the Multipurpose systems. The essential advantages: • Highest flexibility provides certainty in the investment – short set-up times and simple handling • Batch sizes from 5 up to 2.000 l are covered by the X50, X100 and X200 series • Different variants for drives and lifting frames • The adapter X100/X50 offers the possibility to produce batches with a volume of 5 up to 1.000 l with the X100 system • By a simple exchange of the shafts you can use it as a Jetstream Mixer, a Dispermix, a Disperser or as a powder induction and wetting system
