This five-volume handbook provides a comprehensive overview of all important aspects of modern drying technology, including only cutting-edge results.

Volume 2 comprises experimental methods used in various industries and in research in order to design and control drying processes, measure moisture and moisture distributions, characterize particulate material and the internal micro-structure of dried products, and investigate the behavior of particle systems in drying equipment. Key topics include acoustic levitation, near-infrared spectral imaging, magnetic resonance imaging, X-ray tomography, and positron emission tracking.

Unvermeidbar, aber energieintensiv und schwer zu modellieren: Industrielle Trocknungsprozesse sind eine Herausforderung für den forschenden Ingenieur ebenso wie für den Praktiker in der Produktion. Dieses fünfbändige Handbuch stellt sich allen komplizierten Fragen der modernen Trocknungstechnologie von der Berechnung über die experimentelle Untersuchung bis zur Intensivierung und Optimierung. Im Mittelpunkt des zweiten Bandes stehen Verfahren zur Messung des Feuchtegehalts wie akustische Levitation, Taupunktspiegel, Coulometrie, bildgebende IR- und NMR-Spektroskopie sowie Röntgentomographie. Ein- und Mehrteilchensysteme werden erläutert und mit realen Situationen verglichen.
