Spray drying system for drying a liquid feed, consisting of a solution or suspension of particles in a fluid medium. The system enables spray drying of wet material and converting thereof into powder by means of evaporation of a liquid medium at reduced pressure or at vacuum. The system comprises heating chamber and an evacuation means, communicating with interior thereof. This provision enables creating of reduced pressure within the chamber, accompanied by evaporation of fluid medium at temperatures lower than needed for evaporation at normal pressure and evacuation of the moisture vapour, generated during evaporation. |
