A conical jet‐spouted bed dryer with inert bodies was used for drying of animal blood plasma. The effects of the operating conditions on the product properties, final moisture content and throughput of the dryer were investigated. A drying rate model using the conventional rate equation, where the overall effective driving force is based on the surface temperature calculated from the unsteady‐state heat transfer Fourier equation, was proposed. Satisfactory agreement between calculated and experimental results was obtained.
