Calculation of vacuum drying of dispersed materials from multicomponent liquid systems

Calculation methods for different types of drying operations (vacuum-coduct ive drying drying by pressure drop, self-freezing before sublimation) from multiliquid systems were presented. Kinetic relations of vacuum drying were obtained which allow calculation of drying equipment and choise of optimal operating conditions. The existence of balance invariants removing multico mponent liquid systems - single-valued relations between pressure, moisture content, liquid and exhausted vapour phase composition and product tempera ture were found. These relations are used to reduce the number of experimen ts needed to analyze the dryer.
