Abstract: The device for implementing the method comprises a receptacle (3) whose internal profile has the shape of an asymmetric cone (3d) inside which is arranged a blade (5b) of an agitator (5) to agitate with a slow motion the bath of refrigerating liquid contained in the receptacle (3), an orifice (3i) being provided at the bottom of the cone (3d) and communicating with a pipe (3j) wherein is rotationally driven an Archimedean screw (6b) of an extractor device (6) to evacuate continuously the solid particles.

Abstract: Apparatus for the storage and projection of ice balls comprising in combination:a revolving tank terminated by an opening in the lower part for linking with a ball injection chamber (44) to which are fixed:a) a motor (32) able to rotate an axial rod (30) equipped with mixing or stirring blades (36) of an Archimedean screw (38) and, between the two, a means for sealing the passage of the balls (40),b) a jack (34) able to control a translation of the axial rod (30),a gun (4) for projecting the balls and connected to the outlet (58) of the injection chamber,a compressed air source (6),on the gun, a double contact trigger (60), the first contact of which controls the injection of air and the second contact controls the raising jack (34) of the axial rod (30) and the rotation of the motor (32).
