FIELD: chemistry.
SUBSTANCE: in the disclosed microencapsulation method, which includes feeding a coating melt into a fluidised layer of heated granular material, the melt is fed to particles of the granular material through porous heated surfaces located above the fixed layer of granular material and which vibrate in the vertical plane. Temperature of the porous heated surface is 1.05 to 1.25 times the melting point of the coating substance.
EFFECT: high efficiency of the process of microencapsulation of granular materials and the quality of the obtained product owing to contact between the particles of the granular material and the porous heated surfaces, through which the coating melt enters the apparatus and into the fluidised layer of granular material.
