<p>An apparatus and a method for emulsifying a pressurized multi-component liquid by applying ultrasonic energy to a portion of the pressurized multi-component liquid as it is received in a chamber and passed through an orifice. The apparatus (100) includes a die housing (102) which defines a chamber (104) adapted to receive a pressurized multi-component liquid and a means for applying ultrasonic energy (116) to a portion of the pressurized liquid. The die housing (102) further includes an inlet (110) adapted to supply the chamber with the pressurized multi-component liquid, and an exit orifice (112) defined by the walls of a die tip (136). The exit orifice (112) is adapted to emulsify a pressurized multi-component liquid when the means for applying ultrasonic energy is excited with ultrasonic energy while the exit orifice (112) receives pressurized multi-component liquid from the chamber and passes the liquid out of the die housing (102). When the means for applying ultrasonic energy (116) is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip (136). The method involves supplying a pressurized multi-component liquid to the foregoing apparatus (100), applying ultrasonic energy to the pressurized liquid but not the die tip (136) while the exit orifice (112) receives pressurized liquid from the chamber (104), and passing the pressurized liquid out of the exit orifice (112) in the die tip (136) so that the multi-component liquid is emulsified.</p> |
