Mechanical Delinting Process Explained

Delinting cotton seed via mechanic process. 

Cotton Seed Delinting Process: 

1. Seed Delivery and Initial Cleaning: 

   • Cotton seeds are delivered into the seed funnel, preparing them for the delinting process.
   • Feeding rollers, powered by an automatic control motor, rotate face-to-face in the funnel to guide the seeds. 
   • The cotton seeds then drop onto a sliding plate and enter the processing box. 
   • Iron foreign matter is attracted and removed by a magnet on the back of the sliding plate, preventing it from damaging the saw blades. 

2. Formation of Cotton Seed Rolls: 

   • The clean cotton seeds enter the processing box, where the action of the seed stirring roller and the saw blades causes the seeds to form seed rolls. 
   • This action creates a linear velocity difference between the cotton seed rolls and the saw blades, which is crucial for the delinting process. 

3. Delinting Process: 

   • The cotton seeds, hooked by the saw blades, move toward the delinting processing point, where they are separated from the cotton linters. 
   • The separated linters are carried by the saw blades into the cotton brushing system. 

4. Separation of Clean Cotton Seeds and Linter: 

   • The cotton seeds, having less adhesion to the saw blades, are discharged from the system along the rib frame. 
   • The separated linter is brushed off from the saw blades, either by a brush or airflow, and sent to the linter condenser for baling. 

5. Removal of Foreign Matter: 

   • Foreign matter, which has a much greater centrifugal force than the linter, is separated from the linters using an impurity cutting knife. 
   • This foreign matter is then removed from the system by the foreign matter conveyer distributor.
