A magnet module used for producing a carbon nanotube dispersion liquid, comprising: a pipe portion having a first opening connected to a shearing module, and a second opening at both ends; and a magnet disposed in the pipe portion, wherein a medium liquid containing the carbon nanotube defibrated by the shearing module is supplied through the first opening, and after a ferromagnetic impurity attached to the carbon nanotube is attracted to the magnet and removed, the medium liquid is discharged from the second opening.

A system for manufacturing an emulsified/dispersed liquid has first and second emulsification/dispersion devices which produce the emulsified/dispersed liquid by emulsifying/dispersing emulsification/dispersion material in a liquid mixture into a medium liquid in the liquid mixture. A multistage pressure/temperature control device of a multistage type cools the emulsified/dispersed liquid discharged by the second emulsification/dispersion device while applying a backpressure which can prevent occurrence of bubbling to the first and second emulsification/dispersion devices. The multistage pressure/temperature control device reduces the pressure of the emulsified/dispersed liquid gradually or in stages, and finally lowers the pressure of the emulsified/dispersed liquid to a pressure that bubbling is not caused if the emulsification/dispersion liquid is released into an atmospheric condition. The system can apply sufficient shearing force to the liquid mixture so as to sufficiently atomize the emulsification/dispersion material.

System for manufacturing emulsified/dispersed liquid

Disclosed is an agitating device () to be disposed in a batch-type vessel or the like. The agitating device () has an upper cover plate (), a bottom cover plate (), an impeller (), an inner screen member (), and first and second outer screen members (). When a mixed liquid including a dispersoid and a dispersion medium passes through liquid communication holes () of the inner screen member () and liquid communication holes () of the outer screen members () during the course where it flows outward from the impeller () to get out of an interplate space, the circumferential component of the flow vector of the mixed liquid is mostly eliminated to allow the mixed liquid to have substantially only the radial component. This prevents the generation of vortexes so as to apply a sufficiently high shearing force to the mixed liquid to effectively prevent the formation of macro bubbles in the mixed liquid.

Agitating device, and dispersing apparatus using the agitating device

Disclosed is an emulsification/dispersion system, which comprises an emulsification/dispersion apparatus, and a multistage depressurization module connected to the outlet side of the emulsification/dispersion apparatus directly or through a heat exchanger. The multistage depressurization module is provided with a plurality of depressurization cells arranged in a multistage manner through seals, and adapted to apply a given backpressure to the emulsification/dispersion apparatus and to reduce the backpressure in a stepwise manner through the series of depressurization cells so as to prevent the occurrence of bubbling even when an emulsified liquid is released to atmosphere. The present invention can prevent the occurrence of bubbling in both processes of forming an emulsified liquid and taking out the emulsified liquid as a product.

Emulsification/dispersion system using multistage depressurization module and method for producing emulsified/dispersed liquid

The invention relates to a method of manufacturing microcapsules (fat emulsion or liposome) of high stability and smaller mean particle size with a smaller energy and in a shorter treating time. Prior to dispersing a phospholipid treating liquid in a high speed rotary dispersing machine, a treating tank of the high speed rotary dispersing machine is filled up with only the treating liquid. Dispersion of the treating liquid is conducted by rotating at high speed while the treating tank is pressurized to reduce cavitation generation. For precision dispersion of this treating liquid, it is transferred into a precision dispersion apparatus, such as high pressure homogenizer, without contacting with a gas phase. The method reduces the mean particle size of the microcapsules to increase their stability for a long time period.
