Abstract:
An apparatus for encapsulating a substance in small substantially spherical particles formed from an encapsulating fluid, said apparatus comprising:a pulsation chamber containing a movable wall for receiving an encapsulating fluid containing a substance to be encapsulated;a nozzle spaced downstream from the pulsation chamber for receiving the encapsulating fluid containing the substance to be encapsulated from the pulsation chamber;a permanent magnet mounted on the movable wall of the pulsation chamber:a coil spaced from the permanent magnet by an air gap and the coil being located proximate to the permanent magnet;an alternating current source connected to the coil for creating an alternating magnetic wave of the permanent magnet to cause vibration of the permanent magnet and wall attached thereto to result in pulsing of the encapsulating fluid containing the substance to be encapsulated from the pulsation chamber and through the nozzle to encapsulate the substance in small substantially spherical particles formed from the encapsulating fluid.
