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.
