METHOD AND DEVICE FOR FLUIDIZING GRANULAR OR POWDERY BODY

摘要

PROBLEM TO BE SOLVED: To shorten a treating time while suppressing the generation of lump particles. SOLUTION: One or plural spray nozzles 8 for spraying a spray soln. in mist-like by spray air are provided in a treating chamber 4a. The spray nozzle 8, enables a high volume soln. injection of >=700 NL/min spray air flow rate and 360 g/min spray soln. flow rate per one spray nozzle. The treating time per one batch can be shortened compared with the conventional method while suppressing the generation of the lump particles by executing high concn. soln. injection and the high volume soln. injection by using the high volume spray nozzle 8.
