摘要
Calculation methods for different types of drying operations (vacuum-coductive 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 multicomponent liquid systems - single-valued relations between pressure, moisture content, liquid and exhausted vapour phase composition and product temperature were found. These relations are used to reduce the number of experiments needed to analyze the dryer.
