摘要：

This paper presents kinetics of batchwise drying in a spouted bed apparatus with cyclically shifted gas stream, i.e. drying medium flowrate is changed cyclically along inlet cross-section of a bed during operation time. Such an apparatus provides advantages of both spouted and oscillating beds which include: good hydrodynamic conditions within the bed and energy savings. Two types of particulate materials i.e. beet and wheat seeds, which differ largely in physical properties were used in experiments. Based on the results of this investigation formulae for reduced moisture content (X(red)) in dependence on drying time and air temperature were developed.
