Classification of Supercritical Drying Methods and a Reactor Design

Abstract

Although there are many drying techniques in everyday life, most of them are insufficient to protect the structural features of dried products. On the contrary of popular usage of traditional dryings techniques, supercritical drying method provides lots of advantages. Supercritical drying has attracted attention in many areas with superior properties. In this study, supercritical drying methods were investigated and classified. There are basically five types of supercritical drying methods. These are supercritical organic solvent drying, supercritical gas drying, supercritical mixture solvent drying, supercritical gas extraction-drying, and supercritical fluid-assisted spray drying. On the other hand supercritical conditions were specified and a supercritical drying reactor model was created. The model can perform above critical conditions of most substance.
