METHOD OF DRYING OF HEAT-LABILE MATERIALS Russian patent published in 2017 - IPC F26B3/24 F26B3/36 

FIELD: technological processes.

SUBSTANCE: thermolabile materials are first shredded in a shredder 8 down to a predetermined value. Then materials are supplied into the mixer 9 where they are mixed with the substance conformally coating the particles of heat-labile materials, in the amount sufficient for conformal coating. The possible coating material is dry starch or liquid dextrin. During rotation of the screw 5 in particles of coarse vegetable raw material in the outlet 3 in the gap between the rings 6 and 7 the shear stresses occur in combination with pressure, temperature and vapour action. An additional grinding of heat-labile materials with high rate of bond splitting. After the process of conformal coating of materials with starch the evaporation will take place through the film of dextrin and simple sugars without oxygen access.

EFFECT: protection from oxidation of active medicines.
