System for manufacturing emulsified/dispersed liquid

A system for manufacturing an emulsified/dispersed liquid by applying a shearing force to a liquid mixture containing a medium liquid and an emulsification/dispersion material of solid state or liquid state which is not soluble into the medium liquid so as to emulsify or disperse the emulsification/dispersion material into the medium liquid, the system comprising:

• a liquid mixture supplying device for supplying the liquid mixture containing the medium liquid and the emulsification/dispersion material;
• a liquid mixture pressurizing device for pressurizing the liquid mixture supplied by the liquid mixture supplying device and discharging the pressurized liquid mixture therefrom;
• an emulsification/dispersion device adapted to receive the pressurized liquid mixture discharged by the liquid mixture pressurizing device and generate a jet flow of the liquid mixture by transforming pressure energy of the liquid mixture to kinetic energy so as to emulsify/disperse the emulsification/dispersion material in the liquid mixture into the medium liquid in the liquid mixture by means of the shearing force generated by the jet flow to produce the emulsified/dispersed liquid and discharge the emulsified/dispersed liquid therefrom;
• and
• a multistage pressure/temperature control device adapted to receive the emulsified/dispersed liquid discharged by the emulsification/dispersion device and control temperature of the emulsified/dispersed liquid while lowering the pressure of the emulsified/dispersed liquid, and simultaneously to apply a backpressure to the emulsified/dispersed liquid in the emulsification/dispersion device, wherein
• the multistage pressure/temperature control device comprises first to third controllers which are arranged in series from the upstream side to the downstream side with respect to a direction of a flow of the emulsified/dispersed liquid, each of the first to third controllers having a shell through which a heat transfer medium passes and a heat transfer tube arranged in the shell, through which the emulsified/dispersed liquid passes, the heat transfer tubes of the first to third controllers are connected to one another in series, and wherein;
• the first to third controllers have inner diameters, total lengths, and general shapes of the heat transfer tubes which are designed on a basis of a flow rate and viscosity of the emulsified/dispersed liquid in the heat transfer tubes so as to satisfy a relationship of ΔP1>ΔP3>ΔP2, wherein ΔP1, ΔP2 and ΔP3 are amounts of pressure drops in the heat transfer tubes of the first to third controllers, respectively.
