AI Technical Summary
In existing drying equipment, when PVC granules are stirred, the granules come into direct contact with the inner wall of the equipment, causing wear on the inner wall, increasing the resistance to movement, affecting the drying efficiency, and potentially mixing in metal fragments, thus reducing the quality of the granules.
The stainless steel outer barrel is equipped with a circular air-permeable mesh and ceramic stirring blades. A servo motor drives a friction wheel to rotate the air-permeable mesh, preventing the particles from contacting the inner wall. The ceramic stirring blades agitate the PVC particles, achieving uniform heating and efficient drying.
This avoids debris from inner wall wear from mixing into the granules, improving granule purity and drying efficiency, shortening the production cycle, and reducing production costs.
