A method for obtaining a powdered product of raw plant material, according to which preliminary prepared raw plant material is delivered into a drying chamber, in the lower part of which it is comminuted with the aid of at least one activator up to obtaining of the preset particle size and dried in a flow of a gaseous heat-carrying agent, moving in the drying chamber in an upward direction with the speed, which is 1.0-1.5 of free-falling speed of particles. Said particles are then carried over from the drying chamber into a cyclone for collecting the powdered product together with a flow of the gaseous heat-carrying agent. In doing so the flows of the gaseous heat-carrying agent, being formed at the outlet of each heat generator, are entered into the lower part of the drying chamber oppositely to each other, and the speed of a flow of the gaseous heat-carrying agent, coming to the cyclone from the drying chamber, is set up depending on parameters of initial raw plant material. |
