The mixer delivers high consistent homogeneity and above 99% accuracy. And it lets you maximize throughput and number of batches, handling up to ten batches per hour thanks to the twin paddle shaft technology. Based on our database of over 5,000 powders and detailed homogeneity performance trials, we help you select the optimal mixer size, powder filling ratio and cycle time for your specific products. Take the opportunity to perform homogeneity trials with your specific products at our product development centre in Le May-sur-Évre, France.
Thanks to our intensively tested design, this mixer secures paddle clearance and thus eliminates contamination risk. It is also designed for cleanability and is fully openable and inspectable. It has a fully welded top with no seals, edges or sharp corners – and the door seals are dust tight. To minimize powder residue, the internal surface roughness is under 0.8 microns and the inspection doors and outlet hatch are flush with inner surface.
Every element of this mixer is designed to streamline the cleaning process – so cleaning is required less often and takes less time and effort. Inspection hatches allow quick assessment of cleaning needs without stopping production and opening the mixer. The large doors with patented ergonomic handles and cantilevered shaft enable fast and full accessibility to the mixing vessel for cleaning. And our patented new discharge valve is fully dismountable and rotates outward for easy and ergonomic access to the hatch and seals in just a few seconds.
Just 10 minutes for a simple flushing and only 90 minutes and one operator for a thorough cleaning with vacuum and dust-cloth – that’s all you need to clean our new powder-to-powder mixer. This represents the fastest cleaning in the industry and cuts your downtime for cleaning significantly for big savings on your overall operational costs. That’s vital in production where high hygiene is the top priority. In infant formula production, for example, every hour of cleaning time saved is worth approximately €125,000.
This mixer is equipped with synchronized rotating shafts that circulate powder effectively in the mixing vessel. As you can see here, the shafts move in counter-rotating directions from the outer wall to the center of the mixing tank, creating a product fluidization zone (A) and a product circulation zone (B). Paddle mixing ensures quickest, most accurate mixing compared to alternative technologies.
