The company will exhibit its product range at ACHEMA 2024, including its coflow machine

The German machinery and plant manufacturer ystral is showcasing its products at ACHEMA 2024 under the motto "Innovation beats tradition in process engineering". 

The mixing and dispersing technology specialist will be presenting the newly developed continuously operating powder wetting and dispersing machine YSTRAL Coflow for the first time at the leading international trade fair for the process industry in Frankfurt / Germany from June 10 to 14, 2024. 

With its theme-oriented presentation at the exhibition, the machine and plant manufacturer aims to demonstrate in which areas of process engineering the most significant added value can be realised through the use of innovative technologies. 

"Traditional process engineering is often limited by outdated methods and technologies," says Dr Hans-Joachim Jacob, Senior Expert Process and Applications at ystral. "Innovations enable us to overcome these limitations and develop more efficient, sustainable and future-proof solutions – this is what we want to discuss with trade fair visitors." 


YSTRAL Coflow allows uninterrupted production without mixing containers 

To expand its machine portfolio, ystral has developed the continuously operating YSTRAL Coflow, which will be presented to a trade fair audience as a premiere at this year's ACHEMA in Hall 6.0, Stand B49.  

In the YSTRAL Coflow, solids and liquid components are introduced in controlled quantities via solids dosing units or a liquid pump and combined in a premixing zone. 

Fine dispersion then takes place using a rotor-stator system, whereby the stator can be designed with different slot widths depending on the application. "An inducer installed between the premixing zone and the rotor-stator zone is effectuating a pressure increase," says Uwe Klaumünzner, Expert Process and Application Engineering at ystral. "This change in pressure causes the air brought in with the powder to be separated, resulting in a lower residual air content in the product." 


Suitable for a wide range of applications 

The YSTRAL Coflow is designed for a wide range of applications in various industries. The focus lies on products with powders that are easy to process and do not require post-dispersion as well as users with a lean product portfolio or relatively few product changes.

"Compared to a classic batch process in a container, the YSTRAL Coflow enables production with a significantly reduced machine footprint, faster processing times, better OEE values and a higher degree of automation, in addition the cleaning of the machine is much easier due to the smaller product contact surface," says Raoul Pila Nunninger, Head of R&D at ystral and project manager for the development of the YSTRAL Coflow. "The machine is also characterised by its low energy consumption – especially at low viscosities, the Coflow has a minimal power intake." 

For the market launch, the YSTRAL Coflow is available in the size Coflow-4 for production with a total capacity of 6,000-13,500 kg/h. The size Coflow-3 is currently under development and, with a total capacity of 2,000-8,000 kg/h, suitable for small-scale production and for use in pilot plants and technical training centers.
