Preparation device and forming method of three-layer microcapsule

The invention discloses a preparation device and a forming method of a three-layer microcapsule. The preparation device of the three-layer microcapsule comprises a water dropper module, a first water phase feeding device, a first conveying pipe, a vibration element, a second water phase feeding device, a second conveying pipe, an oil phase feeding device, an oil phase conveying pipe, a cooling liquid feeding device, a cooling liquid conveying pipe, a cooling forming pipe, a collecting box and a cooling box. The water dropper module is used for converging the first water phase, the oil phase, the second water phase and the cooling liquid to form a three-layer microcapsule. The preparation device of the three-layer microcapsule can be used for preparing the three-layer microcapsule in one step, the operation is simple, the dripping process is stable, the prepared microcapsule is uniform in size and stable in structure, and the droplet diameter and the interfacial film thickness can be accurately controlled. 本发明
