Abstract
Uniform droplets of a bead-forming liquid are produced by positioning the end of a capillary tube in the throat of a venturi. An immiscible fluid flowing through the venturi detaches the droplets from the end of the capillary tube to produce uniform, spherical droplets which harden into spheroidal beads which have a uniform size.
Claims14
A method of producing uniform spheroidal beads from a bead-forming liquid comprising:
- supplying said liquid to a capillary tube;
- supplying an immiscible fluid which flows through a venturi throat in which the other end of said capillary tube is positioned;
- detaching uniform, spherical droplets of said bead-forming liquid from the other end of said capillary tube by said flow of said immiscible fluid;
- and
- hardening said droplets into uniform spheroidal beads.
