Abstract
A method and a device for making a dispersion or an emulsion (41) from at least two fluids known to be unmiscible, the fluids constituting a dispersed phase (40) and a dispersing phase (44), the dispersed phase (40) being driven through a porous body (24) into the dispersing phase (44). The invention is characterized in that the porous body (24) is vibrated by a mechanical, electrical or magnetic excitation.
Claims14
A method for making an emulsion (41) from at least two liquids, said liquids constituting a dispersed phase (40) and a dispersing phase (44), comprising:
- forcing said dispersed phase (40) from a surrounding portion of a cylindrical porous body through the cylindrical porous body (24) into the dispersing phase (44) within the inner hollow portion of the cylindrical porous body (24), wherein a mechanical excitation system (251) makes the porous body (24) vibrate by applying vibrations directly to said porous body (24), and the mechanical excitation system (251) acts in traction and in compression perpendicularly to an axis of the porous body (24).
A method for making an emulsion (41) from at least two liquids, said liquids constituting a dispersed phase (40) and a dispersing phase (44), comprising:
- forcing said dispersed phase (40) through a porous body (24) into the dispersing phase (44), wherein an excitation system (251) makes the porous body (24) vibrate by applying vibrations directly to said porous body (24),
- wherein a wave in a microwave frequency range, which causes heating of the porous body (24), is superimposed on an excitation at frequencies which generate the vibrations of the porous body.
