SED-800JB-E — Simplified Coating Machine

Tablets are loaded into the 800 mm coating drum which rotates clockwise (0–32 r/min, frequency-converter speed regulation). A fixed deflector plate forces the tablets onto a complex tumbling trajectory, repeatedly passing the spray zone. An RA-C1 high-atomization spray gun, fed by a coating-liquid cylinder and compressed air (4–6 kg/cm²), sprays an even film of atomized coating solution onto the tablets. A controllable hot-air system (internal heater 2 kW + external heater 2 kW, total 4 kW heating power; draft fan 200 W) introduces warmed air at room temperature to 80°C into the drum, rapidly evaporating the solvent so the tablets dry into a solid, smooth, complete film. Drum tilt is adjustable 15–45° (typical 30°) to control tablet motion.
