A process for emulsification which comprises producing an oily phase solution of a hydrophobic material in a dissolving-emulsifying tank equipped with a high speed dispersing means by stirring the hydrophobic material directly or dissolving the hydrophobic material or a hydrophobic material and an emulsifying agent in an organic solvent with heating, forming a water-in-oil emulsion by adding water or water and an emulsifying agent to said solution of the hydrophobic material with stirring, continuing the addition of water or water and the emulsifying agent to form an oil-in-water emulsion by phase inversion, adding a water-soluble binder to said oil-in-water emulsion and stirring the emulsion to form the desired oil-in-water emulsion.

Emulsification process

An apparatus for noodling a gelating dispersion which continuously gels and noodles the gelatin dispersion and supplies noodles of the dispersion into cold water in a washing tank, said apparatus comprising a means for supplying a predetermined quantity of said dispersion to an extruder at a predetermined pressure, said extruder comprising a plurality of supply nozzles that extend from a receiving chamber for said dispersion which are preferably made of a material having higher thermal conductivity than the walls of the chamber, and a washing tank to which cold water has free access, the supply nozzles of said extruder being so arranged as to be immersed in the cold water in said washing tank, to thereby promote gelation of said dispersion flowing down through each of said nozzles and to form firmer and stabler noodles.
