Key Features of Falling Film Evaporator with Long Vertical Tubes

• Long Vertical tubes [6 - 12 meters long, hence smaller diameter]
• Multi tray juice distribution system, ensuring uniform wetting of the tubes and formation of film
• Juice flow from top to bottom in the tubes and formation of film
• Baffle plates provided in the calandria for proper location of tubes
• Efficient steam distribution and adequate number of condensate and vent connections
• Higher evaporation rates
• Short retention time, minimising inversion
• Efficient external centrifugal separator
• Operates at low exhaust pressure as compared to rising film evaporator
• Smaller at plus higher vapour temperature which results in steam economy
