Continuous Vacuum Pan


 Advantages

 
  • Excellent massecuite exhaustion
  • Significant improvement in raw sugar recovery
  • Consistent production conditions
Continuous vacuum pan

 

 Features

 
  • Horizontal pan layout comprising well-mixed cells
  • Small number of cells of optimal individual cell volumes
  • Separate modules with calandria in each module
  • Vertical tube calandria with sloping tube plates
  • Low massecuite boiling head
  • Ensure strong circulation of massecuite
  • Provide uniform conditions for crystal growth at any section along the pan
  • Generate narrow crystal size distribution
  • Provide flexibility of operation with minimal operator supervision
  • Allow easy observation of boiling conditions
  • Permit all operations to be conducted from one side of pan
  • Minimise number of control instruments
  • Provide easy access to calandrias for maintenance
  • Simplify valving and feed pipework
  • Augment production capacity by addition of extra module

 Process Enhancement

 
  • Strong circulation movement in pan allows production of well exhausted massecuite of high dry solid content.
  • Typically for 64 purity C massecuite of high dry, the crystal content in the product exceeds 35% on solids.
  • A minimum of operator supervision while maintaining consistent production performance.
  • Production capacity of Continuous Vacuum Pan is about 30% greater than batch pan of comparable volume.
