GPCG, AGT and GF - fluid bed

When coating in the fluid bed the particles are fluidizied and the coating liquid is sprayed into the bed while drying the particle. No over-wetting is allowed in order to prevent agglomeration of the particles. For many application this technology is sufficient. A complete coverage of the particle surface requires a lot of coating material. Depending on the throughput, batch or continuous units can be used.
