What is Tablet Coating?

Tablet coating is a process where particles tumble in a rotating bed and are coated with a solution. Air is incorporated into the system, which dries the coating onto the particles. The tumbling action facilitates application of an even coating on your particles. 

AVEKA’s tablet coating system creates a controlled atmosphere inside a perforated rotating drum that is ideal for many materials. The no-drip spray design with needle valves ensures precise atomization control coupled with the patterned air flow which creates a uniform particle coating and increases efficiency.
