Level Measurement in Dough Mixers for Pastry Production
Accurately measure dough levels despite the challenge of constantly moving blades in industrial mixers.
Reliable, Continuous Measurement with Non-contacting Radar
Sifted flour, along with pre-measured sugar, yeast and flavorings, are added to an industrial mixer with temperature-controlled water to create dough. The dough mixer is a constantly moving process where mixing blades are used to mix in the additives and to create a smooth-blended product. Given the presence of the moving blades, a non-contacting level measurement is mandatory.
