Air Flow Bed Technology

The Bohle Tablet Coater is equipped with L.B. Bohle’s patented air flow bed technology. This air flow design within the tablet coating pan virtually eliminates the likelihood of spray drying during the tablet coating. It produces a higher spray rate for higher efficiencies and cost savings in pharmaceutical and nutraceutical processing.


Inlet and exhaust air flows are guided through the tablet bed twice, producing a constant flow within the bed and minimizing turbulence above the bed. The air flow cools while in the tablet bed and not in the spray zone so there is no evaporation of suspension. This almost eliminates spray drying, resulting in minimal tablet coating solution loss, uniform tablet surfaces, and a high-quality, defect-free film coat.
