Claims11
A system for coating a fertilizer substrate, the system comprising a mixing unit, wherein the mixing unit comprises a container bowl having an oblate spheroidal configuration and having an inlet portion and an outlet portion, wherein the inlet portion is operatively fastened to a hot air conduit having a blowing unit connected at one end;
- and
- a gel preparation unit and/or a gel dispersing unit,
- wherein the system is adapted to first coat a fertilizer substrate with a gel to form a gel-coated substrate and then coat the gel-coated substrate with a homogenized powder comprising a super absorbent polymer,
- wherein the gel comprises a starch-based superabsorbent polymer, and wherein the hot air conduit is adapted to provide a controlled temperature and flow rate to minimize deformation of the coating and nitrogen leachate.
