Vacuum Pans

Continuous Vacuum Pan

Vacuum Pans

In early 90s, Shrijee introduced the Continuous Vacuum Pan in India, and today Shrijee is one of the largest suppliers of continuous Pans in the world. Modernizing the Pan house in sugar industry involved meeting the requirement of economy in processing by way of increased throughput, improving process efficiencies, economy of steam, energy and manpower. Shrijee in close co-operation with the industry has designed the Continuous Vacuum Pan and over 230 installations in India and abroad have been successfully executed. The capacity range is from 25tons/hour to 100 tons/hour for low-grade massecuite and high- grade massecuite.

Features

  • Heart-shaped profile of Pan to enhance natural circulation.
  • Operator friendly and fully automated.
  • Ensure uniform throughput and product quality.
  • Saves space and energy.
  • Low temperature vapor boiling.
  • Maximized exhaustion of mother liquor.
  • Equipped with multi-baffle entrainment arrestor in SS construction.
  • Single largest capacity (225m3) continuous Pan supplied to KSL (Thailand).
  • Complete automation and control system.
  • Shrijee has successfully increased the capacity of existing Continuous Vacuum Pan by adding new compartments with mechanical circulators.

More than 230 units supplied world-wide


Dual Continuous Pan

Dual Continuous Vacuum Pan

Dual continuous pan can be operated for two different grades of massecuite simultaneously. The Dual continuous pan shall have only one condenser. Heating steam shall be admitted on both ends of the pan and easy to control the steam for the respective massecuite as per the requirement. This pan is having the provision to stop any one of the massecuite boiling without affecting the other massecuite boiling. The calendria will have vertical tubes with peripheral down take. The calendria shall be divided into multiple equal sized compartments to ensure closer approach to plug flow. This Design can ensure better exhaustion of feed molasses.

Advantages of Dual Continuous Pan

  • Simultaneous boiling of two different grades of massecuite.
  • Lesser initial investment compared to individual pans for two different grades for the same output of massecuite.
  • Lesser space is required than the individual pans.
  • Only one condenser, hence water and power saving.
  • Only one condensate extraction system with one pump. Hence saving of power and maintenance cost.
  • Suitable for 100% automation and man power saving.
  • Less steam consumption.
  • High exhaustion due to improved massecuite circulation.
  • Flexibility to run any one massecuite.
  • More exhaustion and high sugar recovery.

Split Continuous Pan

Dual Continuous Vacuum Pan

The split continuous pan shall have one condenser or double condensers as per the size of the pan. Heating steam shall be admitted on both ends of the pan and easy to control the steam as per the requirement. This pan is having the provision to stop either side of 50% for water boiling or to operate at 50% capacity. The calendria will have vertical tubes with peripheral down take and shall be divided into multiple equal sized compartments to ensure closer approach to plug flow. This Design can ensure better exhaustion of feed molasses.

Advantages of Split Continuous Pan

  • Pan can be operated at full capacity or at 50% capacity without effect on performance.
  • Less initial investment compared to individual pans of different capacity.
  • Lesser space is required than the individual pans.
  • One/two condenser as per requirement.
  • Either side of 50% pan can be stopped for water boiling or at 50% Plant crushing capacity.
  • No need of crushing stoppage for water boiling of the continuous pan.
  • Pan can be operated with two different vapour, hence steam saving.
  • Less steam consumption.
  • High exhaustion due to improved massecuite circulation and recovery increase.
  • Suitable for 100% automation.

Multi Down Take Rapid Boiling Batch Pans

Rapid Boiling Pan

Multi down take batch pan is Rapid boiling pan. The pan shall have specially designed multi down takes to provide shortest circulation path for the massecuite so as to ensure higher heat transfer with low temperature and pressure bled vapors. This pan ensures 100% activated zones because of good massecuite circulation and avoids sugar loss due to localized high temperature.

Advantages of Multi-Down Take Rapid Boiling Batch Pans:

  • Suitable for boiling with low pressure and temperature bled vapors, Steam saving.
  • Better circulation and high exhaustion up to 65% and high sugar recovery.
  • Rapid boiling and saving of time up to 0.25-0.5hrs per strike.
  • Higher throughput than the normal pan of same capacity. Increase in pan floor capacity.
  • Less boiling point elevation.
  • No sugar loss due to high massecuite boiling temperature.
  • Suitable for complete automation.
