Kvantificering Blanding med Magnetic Resonance Imaging

Biology
 

Summary

Magnetic resonance imaging (MRI) giver et kraftfuldt værktøj til at evaluere effektiviteten af ​​procesudstyr under drift. Vi diskuterer brugen af ​​MRI til at visualisere blanding i en statisk mixer. Ansøgningen er relevant for produkter til personlig pleje, men kan anvendes til en bred vifte af fødevarer, kemisk, biomasse og biologiske væsker.
