Abstract
Provided is a manufacturing method of particles coated with coatable microparticles. The method is a manufacturing method of particles coated with coatable microparticles, comprising the step of adding the coatable microparticles to an inner core comprising a component of interest and a macromolecule, and, while rolling the mixture, coating the mixture while spraying a solvent that can dissolve the macromolecule, wherein the particles coated with the coatable microparticles are coated, component of interest-containing hollow particles.
Claims8
A method of manufacturing hollow particles coated with coatable microparticles, comprising:
- mixing the coatable microparticles with an inner core comprising a component of interest and a macromolecule such that a mixture is obtained;
- and
- performing coating while rolling the mixture and while spraying a solvent that has a property of dissolving the macromolecule, such that hollow particles including the component of interest and coated with the coatable microparticles are obtained,
- wherein the inner core has a shell and a hollow section.
