Particle.coatin.s are.use. e.te.sive.y to ge.e.ate.dispe.se. solids with we.l-de.in.0} prope.tie., e.g., to prote.t active.in.re.ie.ts, with most coatin. proce.se. usin. core.particle. of a diame.e. large. than.200 μm. This work con.ribute. to the.de.e.opme.t of a coatin. proce.s for fin.0}dispe.se. particle. （diam- e.e. le.s than.50 μm） by combin.n. two particle.formulation.proce.se., n.me.y, coatin. an. spray dryin.. The.fe.sibility of the.ope.ation.is base. on.an. de.on.trate. by the.in.ovative.application.of a two-fluid n.zzle. e.pe.ime.ts we.e.con.ucte. by usin. glass particle. as core.particle. an. sodium be.zoate.as the.coatin. age.t. The.coatin. of fin.0}y dispe.se. particle. is achie.e. by the.sprayin. of particle. an. coatin. solution.as a homoge.e.us suspe.sion. The.aim is to cre.te.drople.s with on.y on.0}con.ain.0} particle.at the.n.zzle.outle.. Afte. e.aporation.of the.wate. in.the.drople., a thin.solid film is built on.the.particle.surface.
