Benefits Of Evaporator Automation:
  • Maintained Heat Transfer Coefficient Optimizes The Evaporation Efficiency
  • Maintained Outlet Brix Of All Bodies Maintains Consistent Efficiency
  • Maintained Body Level And Temperature Of Each Body Hence Excellent Mass Balance Is Achieved Besides Avoiding Entrainment
  • Unnecessary Human Errors Leading To Process Disturbance And Stoppages Are Completely Avoided
  • Huge Power And Water Saving
  • Intelligent Data Analysis With Maintenance And Cleaning Alarming System Reduces Inversion And Improves Sugar Recovery
  • Constant Evaporation Rate Is Maintained, This Increases Overall Efficiency

Application In Sugar Industries For Brix Measurement And Automation Of:

  • Batch Type Vacuum Pan (A, B, C, And Graining Pans)
  • Continuous Vacuum Pan
  • Vertical Continuous Pan
  • Roberts / Semi-Kestner Evaporator
  • Falling Film Evaporators
  • Sugar Melter Automation
  • Molasses Conditioner Juice And Syrup Mixer
  • Baume Of Milk Of Lime

Evaporator Automation:

  • Level Of Evaporator Defines Its Efficiency. The Above Graph Shows The Variation Of The Heat Transfer Coefficient With Juice Level. Even A Small 5% Variation In Level Drastically Reduces The Heat Transfer Coefficient And In Turn, Seriously Reduces The Heating Efficiency Of The Rising Film Evaporator Body.
  • Highly Accurate Sensing Of Fluid-Density-Brix Gives An Accurate Feedback Control.

Evaporator Automation Features:

  • Fluid-Density-Brix Sensing And Control Of The Last Body By Controlling Outlet Control Valve
  • Level And Temperature Sensing Of Each Body
  • Level Control Of Each Body To Maximize Evaporator Efficiency By Optimizing The Heat Transfer Coefficient
  • Heating Steam / Vapour Temperature And Pressure Sensing
  • Level Maintained In Each Body By Controlling Each Body'S Outlet Control Valve
  • Fluid-Density-Brix Maintained In The Last Body And Treated As The Master Control For Previous Bodies
  • Preceding Body Level Synchronization For All Bodies Including Juice Tanks And Cane Carriers
  • Intelligent Data Analysis With Maintenance And Cleaning Alarming System


Exhaust Steam Condensate Bypass System:

  • Exhaust Steam Condensate Conductivity Sensing To Detect Entrainment
  • 3-Way Valve For Exhaust Steam Bypass
  • If Entrainment Is Detected, A 3-Way Valve Is Operated To Bypass The Steam Condensate To Other Line And Not Allow Contaminated Condensate To Enter The Boiler Feed Water

Condenser Automation Advantages From An Evaporator Perspective:

  • Avoid Entrainment Especially In Semi-Condenser Automation Advantages From An Evaporator Perspective:
  • Kestner Due To Uneven Vacuum Shocks And Avoid Time And Resources Wasted In Rework
  • Constant Vacuum
    • Maintained Vacuum Ensures Good Pan Boiling And Evaporation Efficiency
    • Maintained Vacuum Also Ensures Stabilized Vapour Load Thus Heating Efficiency Is Increased

Condenser Automation Philosophy:

  • Vapour Vacuum And Temperature Sensed
  • Condensate Temperature Sensed In Tail Pipe
  • Temperature Difference Calculated
  • Vacuum And Temperature Difference Are Both Analyzed To Derive Remote Dynamic Set Point
  • Spray Water Is Controlled As Below:
    • Multi-Entry System:
      • Spray Jets Are Controlled By Separate On/Off Type Control Valves As Per The Remote Dynamic Set-Point
      • 2, 3, Or 4 Sets Of Nozzles For Spray As Per Design
      • 1 Or 2 Sets Of Jet Nozzles As Per Design Are Controlled Only If Necessary
    • Single-Entry System:
      • Spray Jets Are Controlled By A Control Valve In Pid Action As Per The Remote Dynamic Set-Point
      • 1 or 2 Sets Of Jet Nozzles As Per Design Are Controlled Only If Necessary
