Quantificare miscelazione con risonanza magnetica

Biology
 

Summary

Risonanza magnetica (MRI) fornisce un potente strumento per valutare l'efficacia delle apparecchiature di processo durante il funzionamento. Noi discutere l'uso della risonanza magnetica per visualizzare miscelazione con miscelatore statico. L'applicazione è rilevante per prodotti per la cura personale, ma può essere applicata a una vasta gamma di fluidi alimentari, chimiche, le biomasse e biologici.
