Abstract
A method of preparing droplets wherein a dispersion phase, insoluble or sparingly soluble in water, is injected in the form of a laminar flow into an aqueous continuous phase through an orifice. The viscosity ratio between the two phases is adjusted to a specific range to produce droplets of uniform diameter at a specified jet velocity.
Claims6
A method of preparing droplets without forced vibration wherein a dispersion phase insoluble or sparingly soluble in an aqueous continuous phase is injected in the form of a laminar flow into the continuous phase through an orifice, the method being characterized in that when the viscosity of the dispersion phase is .mu.' and the viscosity of the continuous phase is .mu., the viscosity ratio .mu.'/.mu. between the two phases is adjusted to the range of from 0.9 to 4 to produce droplets having a uniform diameter without using forced vibration.
