Kvantifisering Mixing bruke Magnetic Resonance Imaging

Biology
 

Summary

Magnetic resonance imaging (MRI) gir et kraftig verktøy for å evaluere effektiviteten av prosessutstyr under drift. Vi diskuterer bruken av MR for å visualisere blande i en statisk mikser. Søknaden er relevant for produkter til personlig pleie, men kan brukes til et bredt spekter av mat, kjemiske, biomasse og biologiske væsker.
