AI Technical Summary
The existing wet mixing granulator's stirring paddle is prone to uneven granulation. The paddle and the pot have a large contact area and high friction, which increases energy consumption and internal temperature, affecting pharmaceutical stability.
A stirring paddle consisting of a stirring base, three paddle arms and three bending plates was designed. The angle between the paddle arms and the bending plates was 150°. Combined with a protective component, the contact area between the paddle blades and the pot body was reduced. The rotation of the stirring base, paddle arms and bending plates made the material tumble, avoiding the formation of laminar flow and reducing energy consumption and temperature.
It achieves more uniform mixing of materials, reduces energy consumption and internal temperature, improves pharmaceutical stability and cleaning convenience, and avoids the occurrence of uneven granulation.
