GEA Liquid Processing in Skanderborg Denmark, part of GEA Process Engineering, has developed a new type of inline mixing system for the food and beverage industry. The new technology, called Multi-Rota™ significantly reduces energy, equipment and maintenance costs for processing plants.
Inline mixing plants are used throughout the food and beverage industry for the single or multi-pass mixing of dissolvable powders up to 400cP. This includes applications such as milk recombination, juice concentration, beverage preparation and the manufacture of base slurries.
The innovation is to the design of the mixing rota. The Multi-Rota™ as the new design is called, is designed not only to create the necessary sheering force to mix the product but also to develop sufficient centrifugal pressure to pump the product to the storage silos without the need of a separate centrifugal pump. This is achieved by splitting the vanes of the rota around the stator to create the necessary external pressure.
The new development offers a number of benefits over current technology. Firstly, eliminating the need for a separate centrifugal pump immediately reduces capital, installation and maintenance costs. Secondly, the increased pressure means that storage silos can be re-circulated more quickly reducing batch processing time. Finally, tests have proven that the new system is significantly more efficient than existing systems cutting power usage by up to 15%.
Claus Patscheider is the Area Sales Manager at GEA Liquid Processing. “Motors for this type of mixing equipment are usually 75kW or 55 kW. In tests we have been using 45kW motors so the power usage will be much lower,” he explained. “We have been very impressed with the new design and are now very close to releasing it onto the market. It is a major leap forward in technology for the food and beverage industry.”
Inline mixing is the preferred technology for food and beverage plants that require the high volume mixing of low viscosity products.
