Embodiment 1

[0015] One embodiment of the present invention is a device for manufacturing composite microcapsules based on composite microspray. Such as figure 1 As shown, the composite microspray structure is composed of an inner nozzle 1 and an outer nozzle 2, and the inner nozzle 1 is inserted into the outer nozzle 2. The inner nozzle 1 communicates with the first pump 3 , the outer nozzle 2 communicates with the second pump 4 , and both the first pump 3 and the second pump 4 are micro-pulse pumps. The outer nozzle 2 is inserted into the micropipe 5, and the joint is sealed by a seal 6 to prevent leakage. One side of the micro-pipeline 5 is connected to the third pump 7, and the opening of the other side has a sieve conveyor 8, and a collector 9 is arranged below the sieve conveyor 8. The composite microspray structure can be made of glass or metal. The minimum size of the inner nozzle 1 is about 100 microns, and the size of the outer nozzle 2 is generally 10 times that of the inner n...
