According to the equipment for rapidly and continuously manufacturing droplet microspheres and the application, continuous phases and dispersed phases are conveyed into the continuous phase pressure tank continuously to achieve rapid and continuous material supply, and rotating blades play a role in assisting in material supply, so that working efficiency is improved; liquid drops are brought into a discharge device through inlet air in an air chamber, and the droplet microspheres are prepared efficiently, rapidly and continuously.

Description

Technical field [0001] The invention relates to a device for rapidly and continuously preparing droplet microspheres and its application, and belongs to the technical field of droplet microsphere preparation. Background technique [0002] Micro-droplets have many excellent properties such as small size, no diffusion between droplets, avoiding cross-contamination between droplets, stable reaction conditions, controllable mixing and many other excellent properties, and are more and more widely used. The droplet size uniformity (monodispersity) obtained by traditional mechanical stirring and colloid milling methods is poor; the microfluidic technology based on hydrodynamics is currently the main method for producing monodisperse microdroplets, but the rate is at ml / H level, although the micro-droplet growth rate can be improved by integrated micro-channels, it is still difficult to reach the order of l / h, and the mutual influence between multiple channels is large, which reduces th...
