Tablet Coating Machine

The machine works by rotating a coating pan at variable speeds while tablets (loaded at 50–80% fill volume) tumble inside. A spraying system (often with a peristaltic pump) applies the coating solution in controlled pulses. Simultaneously, a hot air blower system supplies heated air (typically 50–80°C) to dry the coating evenly. The process includes pre-heating, spraying, drying, optional curing, and unloading stages for a smooth, uniform finish.

Key features include a compact GMP-compliant design, sanitary stainless steel pan with welded baffles for excellent tablet rolling, adjustable pan angle, interchangeable pans for different capacities, optional spraying system with peristaltic pump, quick-adjust spray guns, exhaust blower, and advanced options like PLC/HMI controls and IQ/OQ documentation. Safety features include interlocked heaters that activate only when the blower is on.

The machines are available in various pan sizes from lab-scale (e.g., 8-inch) to industrial models up to 72 inches. Standard models include ACP 18” (12 L), ACP 30” (40 L), ACP 36” (75 L), ACP 42” (125 L), ACP 48” (200 L), ACP 60” (310 L), and ACP 72” (520 L) working capacities, with corresponding blower and motor specifications to suit different batch sizes.

Advantages include uniform coating thickness for consistent quality, improved product stability and shelf life, compliance with GMP standards, scalability from lab (1 kg) to large production batches (300+ kg), precise process control (temperature, spray rate, pan speed), and enhanced tablet appearance, taste-masking, and controlled-release capabilities. Custom flameproof/explosion-proof options are also available.
