Abstract

The invention discloses a three-dimensional parallel device for rapidly preparing multiple emulsions. The apparatus comprises an inner fluid distribution channel which is connected with an inner fluid inlet adapter tube; a plurality of outer fluid distribution channels which are respectively connected with outer fluid inlet adapter tubes; an emulsion collecting channel which is connected with an outlet adapter tube; and a plurality of emulsion generating units connected between the inner fluid distribution channel and the emulsion collecting channel and respectively connected with the outer fluid distribution channels. The three-dimensional parallel device for rapidly preparing multiple emulsions, adopting modular design, has the advantages of good expandability, high space utilization rate, realization of rapid and highly-efficient production of the multiple emulsions, uniformity in distribution of the fluid in the device, and avoiding of flowing dead zones, so the high monodispersbility and the high uniformity of emulsion production are guaranteed.

Description

technical field [0001] The invention relates to the field of preparation of multiple emulsions, in particular to a three-dimensional parallel multiple emulsion rapid preparation device. Background technique [0002] Multiple emulsion is a highly structured special multiphase fluid structure, which is composed of multicomponent fluids nested in each other. The special core-shell structure of multiple emulsion droplets makes it suitable for selective extraction, purification, oral administration, toxin absorption in gastrointestinal tract, etc. It has a wide range of applications in biomedicine, food, chemical and other industries. Traditional multiple emulsion preparation methods usually have many problems such as low sphericity, non-uniform droplet size and poor monodispersity of the obtained multiple emulsion droplets. In addition, the distribution channel of the traditional production device is very long, the flow dead zone is large, and the preparation efficiency is low....
