Process time

Is your process too time-consuming? Are your process systems in production occupied for too long to be efficient? In most cases, processes can be made more efficient. Our experienced experts can help you to significantly reduce process times: with the plant engineering, machines and concepts – tailored to your individual mixing requirements.

Space requirements

Would you like to increase your capacity, but your available space is already exhausted? By modifying your existing process and/or relying on new technologies, you can still reach your goal. We will be happy to analyse together which solution will add the most value to your production. Often a closer look reveals that no more space is needed at all to increase the capacity of a plant.

Resources and energy

In your industries, are energy and resources critical cost factors? Often, a few adjustments in production can reduce costs considerably. We have proven time and again that, with a plant analysed and improved by our process engineers, we will achieve significant resource savings and a fast ROI.

Four times passion in action


Do you know when an idea just won’t let you go? That is how our process and application engineering experts sometimes feel, even after hours. The following videos show just how much creativity is produced when “the mind is always on mixing”. Have fun watching!

Chez ystral, nous faisons la distinction entre mélanger et agiter.

Il suffit de regarder combien de temps d’agitation vous avez actuellement prévu dans vos protocoles de traitement par lots. Vous pouvez agiter le contenu d’une cuve procédé dans un mouvement circulaire pendant longtemps, il n’en deviendra pas plus homogène. Ce n’est pas possible, car l’inertie du liquide en rotation horizontale entrave la circulation verticale. Au cours du webinaire, vous ferez l’expérience de différents agitateurs dans des cuves procédé et de grands récipients en verre et pourrez ensuite vous faire votre propre image de ce qui se passe dans vos cuves.

A contrario, nous nous appuyons sur un principe de mélange systématiquement vertical, le mélange par jet dirigé. En un temps très court, le produit est mélangé intégralement et de façon totalement homogène. La différence est énorme. Si on remplace un agitateur par un mélangeur à jet dirigé, il faudra moins d’un dixième du temps, un dixième des cuves procédé et un tiers de l’énergie.
En env. ¾ d’heures, nous vous donnerons un aperçu de ce que vous n’avez probablement jamais vu auparavant. Et certainement, il vous suffira simplement d’équiper vos installations procédé de nouveaux mélangeurs pour doubler leur efficacité.

How our experts guide you to your perfect plan

Step by step to achieving the individual optimum

What good is an ingenious mixing process concept if there are problems in production? And no matter how high the quality of fabrication, you will not achieve the desired result in terms of efficiency and profitability, if sufficient testing was not carried out during development, or if commissioning is not carried out with the greatest possible care. What you need and what we at ystral deliver is a comprehensive service with a fast return on investment:

From the start of the project to the moment the machine is running. And keeps on running.

From needs assessment to initial analysis

From the very beginning, we deal intensively with you and your requirements. An experienced process and application engineering expert accompanies you from the initial discussion to the acceptance of your new system – with dedication and practical knowledge. Together, we clarify your exact requirements and leave no stone unturned. This is because the more precise the task and basic data, the more accurately we can calculate your solution. As a result, you receive a mix of optimal machine technology, leaner processes and improved formulas.

From analysis to the test centre

With our process engineers, you develop new, efficient production processes. Or you can optimise existing ones. In our test centre, almost the entire range of ystral machines – from laboratory to production scale – is available to you for this purpose. Even seasoned process professionals learn new things about their process and raw materials here time and again. This is how – step by step and with great teamwork – the first concept for your new plant is created. Then we continue to test and optimise together. Not to determine what the maximum technically feasible option is, but rather to find your own individual optimum.

From the concept to the built system

Based on the ensuing analysis, we define the requirements for main components and machines. The result: a plant concept including flow charts and diagrams ready for implementation. An informative offer then rounds off the concept phase. Once you have decided on the implementation, you will receive a modelled 3D layout with all the important elements for process, operation, integration and maintenance. Before we build the plant, we check all documents together with you. On this basis, we manufacture the required components for your plants and machines at our premises. We then assemble them in the assembly hall until the turnkey system is ready.


Commissioning and start-up of your new system

When the day of initial acceptance arrives, the system is delivered to you and set up. The installation is carried out by yourself or your contractual partners, if desired, under the direction of our application engineers. If you wish, we can take over responsibility for installation and connection completely by arrangement. After completion of the installation and set-up phases, the system is commissioned and adjusted to fit various parameters. This is followed by the final acceptance from your side. And that’s it. Together, we have created a system with tangible added value.

Technical articles and success stories

In specific terms: our applications

With the help of technical articles, case studies and success stories with (and without) a specific customer reference, you can build an idea here of how we advise, develop and produce. This is what the day-to-day practice of our process and application engineering experts, our measurable results and our extraordinary added-value look like.


In the beginning, YSTRAL machines and plant engineering were mainly used in the food industry. But, since the 1970s, our machines have been used in many different sectors. In the chemical industry, for example, they are used in the production of lacquers, paints and coatings, as well as in adhesives, sealants and insulating materials. Do you want to produce a cleaning or care product? No problem for our machines and systems. In the cosmetics industry, ystral machines are used to produce deodorants, fragrances, gels, hair lacquers, shampoos and sunscreens. In the pharmaceutical industry, they are used for gels, ointments, suspensions and tablet coatings. As our machines and equipment are extremely versatile, we look forward to every new challenge.

Yes, trials are generally possible in the presence of the customer, provided that all currently applicable guidelines are adhered to. At the moment, this would mean, for example, that if the customer is coming from a high-risk area, a meeting is only possible after the required quarantine of at least 5 days and a negative coronavirus test. Alternatively, the trial can take place without customers, with an appropriate protocol and the collection of samples. Or we can provide you with test machines on loan. Meaning that you can test them and perform your own trials on-site.

In principle, trials can be carried out with flammable or explosive media. However, safety data sheets are required for this. Some H-phrases are excluded if, for example, substances are involved that are toxic upon skin contact or inhalation, or that are explosive (even without oxygen). For more detailed information on this, please feel free to contact us at any time.

Provided that current government regulations are adhered to, a wide variety of trials can be carried out on-site at the centre. Together with our process engineers, you can develop new efficient production processes or improve existing ones. All with original ystral machines and your raw materials. Discover a whole new side to them. The trials are documented in detail. If you prefer to test in your familiar environment, you can rent ystral test machines. We will be happy to accompany you during the trials on-site and during commissioning.

We use the optical microscope to examine your samples with regard to various factors: Both density measurement and particle size analysis with dynamic light scattering are possible. We can also determine viscosities using various measuring methods with and without tempering, and we can plot curves of various shear rates. We are also happy to take care of sample collection and return.

From the very beginning, we deal intensively with your requirements, your inquiry and you. The requirement definition and initial analysis are, therefore, steps of intensive cooperation between our process engineers and you. Then we go to the test centre together to get to know your formulas, processes and raw materials better. An initial concept is developed from these collected findings. Once the concept has been approved, it is time to build the new plant and put it into operation together.
