- B01F 31/10 with a mixing receptacle rotating alternately in opposite directions
- B01F 31/20 Mixing the contents of independent containers, e.g. test tubes
- B01F 31/29 Mixing by periodically deforming flexible tubular members through which the material is flowing
- B01F 31/30 comprising a receptacle to only a part of which the shaking, oscillating, or vibrating movement is imparted
- B01F 31/40 with an axially oscillating rotary stirrer
- B01F 31/42 with pendulum stirrers, i.e. with stirrers suspended so as to oscillate about fixed points or axes
- B01F 31/44 with stirrers performing an oscillatory, vibratory or shaking movement (B01F31/40, B01F31/42 take precedence)
- B01F 31/46 with an annular vibrating trough
- B01F 31/50 with a receptacle submitted to a combination of movements, i.e. at least one vibratory or oscillatory movement
- B01F 31/55 the materials to be mixed being contained in a flexible bag submitted to periodical deformation
- B01F 31/60 with a vibrating receptacle (B01F31/10, B01F31/20, B01F31/50 take precedence)
- B01F 31/65 the materials to be mixed being directly submitted to a pulsating movement, e.g. by means of an oscillating piston or air column
- B01F 31/80 Mixing by means of high-frequency vibrations above one kHz, e.g. ultrasonic vibrations
