High-Efficiency Bohle Tablet Coater

L.B. Bohle has developed the future of tablet coating, the high-efficiency Bohle Tablet Coater (BTC). The tablet coater reduces processing times up to 35 percent compared to conventional tablet coating systems, yielding significant cost savings and improved campaign efficiency while maintaining cGMP standards.

The BTC provides superior coating uniformity, producing considerably fewer rejects and using less coating material. L.B. Bohle’s patented air flow bed technology eliminates spray drying, thereby reducing waste while lengthening campaigns between cleaning. It also promotes uniform tablet coating with a high-quality, defect-free film coat.

The tablet coater’s elongated coating pan provides a larger tablet spraying surface accommodating up to 10 spray nozzles, which delivers more suspension solution and reduces overall coating time. The BTC’s integrated mixing baffles are double-helix shaped to ensure thorough tablet mixing with gentle handling. The baffle design provides 100-percent tablet discharge, increasing campaign efficiency.

The BTC is ergonomically designed for efficient material handling and is capable of Wash-in-Place (WIP) cleaning. The BTC spray arm and nozzles are mounted on the front door assembly, simplifying inspection and maintenance.

Benefits of the Bohle coating technology:

• Excellent mixing thanks to patented spirals • Careful product movement thanks to low tablet bed thickness • Easy discharge by changing the rotating direction of the pan • Nozzles with ABC caps ensure long service life • Highly efficient suspension system thanks to the reduction of spraying losses • Faster processing due to a high number of nozzles and an efficient air system • High batch size variability from approx. 35 to 100% filling volume • Same pan geometries for easy scale-up • Rapid and simple cleaning

The L.B. Bohle Coating products:

• Bohle Tablet Coater BTC • Bohle Film Coater BFC TriPan • Bohle Film Coater BFC
