FIELD: drying and granulation equipment. SUBSTANCE: drying and granulation is effected due to thermal treatment of moistened mass of aspartam crystals with use of hot carrier gas. Moistened mass of aspartam crystals are fed into high-speed blade-type drier which is provided with heating jacket with heating temperature of 80-190 C and blades mounted on central shaft with adjustable rotation speed. Also adjustable in process of rotation is distance to blades and their angle in relation to jacket and they are located so that preset size of granules can be produced. Rotation speed is selected so that Froude number is larger than 1. Supplied material must be processed in blade-type drier during 15-600 s at simultaneous presence of carrier gas with its temperature at inlet being 100-200 C. Obtained granulated product is discharged from blade-type drier and if necessary is additionally dried by one or more stages in other drying equipment. EFFECT: high efficiency. 13 cl, 5 tbl
