Abstract

An apparatus for mixing and dispersing powdered or granular materials into a liquid solvent with a pneumatic transport means including a supply hooper, a pressure vessel which receives granular materials from the hopper for pressurization, a granular material transport pipe attached at one end to the discharge portion of the pressure vessel, a pneumatic force source for feeding the granular materials under pressure through the granular material transport pipe to a mixing tank accommodating the liquid solvent therein. The granular material transport pipe is connected to the mixing tank in an upward or lateral direction at the level below the surface of the liquid solvent contained in the mixing tank. With this structure the granular material is kept from scattering towards the upper portion of the mixing tank, making the operation more sanitary. Further, since the granular material is fed into the solvent contained in the mixing tank by pressurized feeding gas, a uniform mixing may be achieve, and the formation of undissolved powder lumps or flocs can be prevented.
