RheoStream® – rheology on track

RheoStream® is a rheometer for real time in-process measurement of shear thinning, apparent yield stress and viscoelasticity in viscous non-Newtonian liquids like paint, detergent, soap, skin care, sauces and dressings.

The end product may be creams or liquids, emulsions or suspensions, or it may be a solid after having passed through liquid stages. In any case the production process will transfer and convert raw materials through multiple stages, and RheoStream® will measure the rheological properties to guide potential adjustments ensuring the liquid can be pumped, mixed, filled and stored.

When products are used, the consumer perception and the functionality also rely on properly balanced rheology – will a paint run, does the cleaner cling to the surface and will the lotion hydrate the skin? RheoStream® helps secure a consistent quality.

In-process rheometer

RheoStream® is implemented directly in the production process, right next to the liquid to be measured. It pulls out frequent samples which are handled and analyzed in the instrument. The instrument supplies data to the factory control system and allows for manual or automated control of the process.

Replacing today’s common practices

RheoStream® is a new alternative replacing the two most common practices for measuring flow qualities:

  • Inline viscometers providing real time data on viscosity
  • Manual in-plant or laboratory rheometers providing full set of rheology data

While the two common practices either provides you with too little data or provides you with the data too late for making adjustments, RheoStream® will provide you with a full set of real-time rheology data.

With real time measurements it is possible to intervene and adjust a manufacturing process in time to keep it on track by adding thickener, diluting with solvent or other corrective processes.

The benefits of using RheoStream®

By implementing RheoStream® you get the opportunity to:

  • Reduce off-spec rate and rework – with real time rheology information the production process can be continuously regulated, ensuring that the processed liquids comply with specification limits.
  • Optimize capacity and resource utilization – a controlled process reduces the need for reworking off-spec material and this frees up capacity and enables a larger throughput.
  • Streamline your value chain – when every batch and every ton produced meets the specification the output is predictable, allowing for an optimized and streamlined supply chain.
  • Gather data for big data analysis / smart manufacturing / Industry 4.0 – with so many parameters to adjust in a process and so few real insights into the actual properties of the liquid inside the stainless steel it is challenging to establish a model-based understanding of process performance. Adding rheology to the picture enhances the understanding of process performance, both on the shop floor and in digital models.
