PROBLEM TO BE SOLVED: To provide a throwing-in apparatus of powdery and granular material and a throwing-in method for the material showing excellent working efficiency and working safety in throwing-in the powdery and granular material to be cut off from oxygen.;SOLUTION: The throwing-in nozzle 3 is equipped with a throwing-in pipe 52 having one edge inserted into a bag 15 to throw bisphenol A in the bag 15, an injection pipe 51 having another edge inserted into the bag 15 to inject nitrogen gas in the bag 15 and an exhaust pipe 53 having one edge tightly connected with the bag 15 to exhaust air in the bag 15. By the throwing-in nozzle 3, another equipment to make inner gas (nitrogen gas) atmosphere in the bag 15 is not necessitated, and the working efficiency in attachment of the throwing-in nozzle 3 is good. Accordingly the throwing-in nozzle 3 shows the excellent working efficiency in the attaching operation.;COPYRIGHT: (C)2004,JPO
