The trends of modernization and improvement of the technology and technical equipment for the powder food supplements made of germinated grain are presented. The experimental apparatus for the thermal and chemical processing of the humid alimentary products is developed and shown. The technological parameters of the thermo-mechanical processing of the rye are analyzed. The design of a dryer and the principle of its operation are described. The dryer allows simultaneous drying and crushing of grain crops and producing ready food additives in the form of powder. On the basis of experimental research the analysis of the combined crushing and drying processes in the dryer for sprouted grains is made. Data on the fractional structure of prepared powders depending on the moisture content of the processed product, installation productivity and a grinder rotation frequency are obtained. Quality indicators of the crushing process for sprouted grains in the form of the dependence between the crushing degree and the Froude number are defined. The presented unit (drying-disperser) allows to extend the technological abilities of the dryers and to increase the drying process of the humid, lump and clammy materials
