Abstract:The influence for flow granulating of traditional Chinese mediciue to be taken after being mixed with boiling water: spray air pressure>powder granularity>inlet, exit temperature>wind speed. Optimum condition: inlet temperature 110℃, exit temperature 50℃; spray air pressure 1.0kgf/cm~2; sugar powder granularity: 40～60 eye; wind speed: 1.5 gear. It is necessary to provide reference basis for production by pilot test.
