FIELD: prevention of agglomeration of viscous particles at drying in a boiling layer. SUBSTANCE: the method consists in feeding of viscous particles through the boiling layer; air flow for drying is fed upwards through a perforated container to the viscous particles. The viscous particles are subjected to the effect of the flow of pulsating air. The feeding of the air flow for drying and the flow of pulsating air, pulsation and air temperature are controlled. The invention concerns also the installation of the boiling layer providing prevention of agglomeration in the process of drying; the installation has a means for introduction of viscous particles onto the upper surface of the perforated container made for movement of viscous particles through the boiling layer, output facility for discharge of viscous particles, means for feeding of air for drying and pulsating air. EFFECT: single-stage method for drying of viscous particles, prevented agglomeration, drying of a great quantity of viscous particles, preserved good surface properties. 32 cl, 2 dwg
