Particle.coatings are.use. e.te.sive.y to ge.e.ate.dispe.se. solids with we.l-de.ine. prope.tie., e.g., to prote.t active.ingre.ie.ts, with most coating proce.se. using core.particle. of a diame.e. large. than 200 μm. This work contribute. to the.de.e.opme.t of a coating proce.s for fine.dispe.se. particle. （diam- e.e. le.s than 50 μm） by combining two particle.formulation proce.se., name.y, coating and spray drying. The.fe.sibility of the.ope.ation is base. on and de.onstrate. by the.innovative.application of a two-fluid nozzle. e.pe.ime.ts we.e.conducte. by using glass particle. as core.particle. and sodium be.zoate.as the.coating age.t. The.coating of fine.y dispe.se. particle. is achie.e. by the.spraying of particle. and coating solution as a homoge.e.us suspe.sion. The.aim is to cre.te.drople.s with only one.containe. particle.at the.nozzle.outle.. Afte. e.aporation of the.wate. in the.drople., a thin solid film is built on the.particle.surface.

Proble.s associate. with land de.radation are.se.ious in China.
