FIELD: chemical or physical processes.

SUBSTANCE: present invention relates to methods of producing solid amino acid-containing mixtures and an apparatus for producing such mixtures. L-amino acids are used as components of pharmaceutical raw materials, food additives, animal feedstuffs, nutrients, insecticides and bactericides. Method of producing a solid mixture containing an amino acid includes a first step for preparing a solution of a mixture containing an amino acid, second step of mixing the solution of the mixture containing the amino acid to form a thin film, drying and spraying the formed thin film to obtain wet granules and a third step of drying the wet granules to obtain a solid granular composition containing the amino acid. Second step of drying the solution containing the amino acid is performed so that the concentration of the solid substance in the wet granules is in the concentration range, suitable for granulation.

EFFECT: providing a method and apparatus which enable to obtain a granular mixture containing an amino acid with high efficiency.
