Apparatus for preparing encapsulated bodies

Abstract

An apparatus for the production of encapsulated bodies employing a dropping tank for a fluid to form the cores of the encapsulated bodies and a reaction tank containing a solution capable of forming gel skins upon contact with the core material in communication therewith. Double-walled cylindrical nozzles are arranged in a lower part of the drop tank, the inner and outer walls of the double-walled cylindrical nozzles being coaxial. A pressurized air feed pipe is in communication with an upper part of the dropping tank. The peripheral walls of the reaction tank are in the form of a double-walled cylinder whose upper peripheral portion of its inner wall contains a screen. A liquid feed pipe and a capsule discharge port are provided in communication with the interior of the reaction tank through lower parts of the double-walled cylinder. A liquid discharge port also is provided in communication with an annular spacing of the double-walled cylinder through its outer wall. The apparatus provides for obtaining a dispersion of encapsulated bodies without their mechanical separation from the liquid in which they are prepared.
