AI Technical Summary
Existing pharmaceutical fluidized bed discharges are not clean, with a large amount of residue, requiring manual cleaning after shutdown. The discharge valve sealing structure is easily damaged and difficult to clean.
Design a fluidized bed structure including an air inlet assembly, a fluidized bed body, an exhaust assembly, and a lifting dry granulator. The material is spiraled and automatically discharged through the discharge valve of the cyclone distribution plate and the anti-torsion cylinder. Combined with telescopic cleaning balls and non-metallic seals, sealing performance and easy cleaning are ensured.
It achieves automated discharge of fluidized bed material, reduces manual cleaning costs, improves sealing effect and cleaning efficiency, and solves the problem of unclean discharge.
