Tablet coating machine accurately deposits controlled amounts of coating materials on tablets, even if they are extremely hygroscopic or friable. The tablets are coated with the coating spray in the same direction as the drying gas, resulting in a more efficient process. Due to supercell™ coating technology's unique air distribution plate design, the tablets move quickly and predictably through the spray zone, receiving only a small amount of coating per pass, and therefore achieving higher coating accuracy. The process time is short, seconds or minutes as opposed to hours and therefore gentler on the tablets. Supercell™ coating technology allows for coating of friable tablets, as well as, flat or highly oblong tablet shapes. Drying is very fast, making it possible to coat extremely hydroscopic tablets. The accuracy of deposition is great enough that active pharmaceutical ingredients can be layered onto tablets, and uniform layers of taste masking or modified release coatings can be added in a single continuous batch without resulting in any problems.
