METHOD OF DEPOSITION OF THE COATING ON THE PARTICLES OF THE BULK MATERIALS Russian patent published in 2006 - IPC B01J2/16 B05D1/22 

FIELD: chemical industry; food industry; pharmaceutical industry; other industries; methods of deposition of coatings on the particles of the bulk materials.

SUBSTANCE: the invention is pertaining to the method of deposition of coatings on the particles of the bulk materials and may be used in chemical, food, pharmaceutical and other industries. The technical result of the invention is the increased efficiency and the improved quality of the product. The method of deposition of coatings on the particles of the bulk materials provides for the coating melt atomization of a melt of cover by the gas heated above the fusion point of the coating material into the liquated layer of the particles of the bulk material. The bulk material preliminary is heated up to the temperature of 0.5-0.6 of the fusion points of the coating material by the flow of the fluidizing agent. At dosage of the melt the temperature in the liquefied layer of the bulk material makes no more than 0.6-0.8 of the temperature of the coating materials fusion points. After termination of the batching of the melt conduct the gradual reduction of the temperature of the layer of the material up to the temperature of the environment.

EFFECT: the invention ensures the increased efficiency and the improved quality of the products.
