Evaporators Falling or rising film

Modern evaporators designed foroptimal performance and reliability

Easy installation • Local fabrication ensures rapid delivery and lower cost• Easy adaptation: small footprint; outdoor installation possible;

easy integration in existing multiple effect stations

Outstanding performance• High heat-exchange coefficient for both beet and cane

applications thanks to specific and well adapted designs

• Low ΔT on all juices (high or low brix)

Unrivalled reliability• Integrated skirt protects the tube bundle from vibrations• Proven designs ensure maximum sugar yield

Easy maintenance • Falling film (beet design): low risk of fouling and minimal juice

colour increase thanks to short retention time• Falling film (cane design): removable upper part facilitates

cleaning (cleaning frequency reduced by 2 to 3)

Fives Cail has been providing outstanding evaporators to its customers

for more than 150 years. Drawing on this long experience, the Group

continues to revolutionize evaporator technology by efficiently

adapting the falling film to cane sugar processing. It has built the

world’s largest evaporator, with an exchange area of 7,540 m².

Fives Cail now offers 3 distinct evaporator designs perfectly adapted

to beet and cane sugar plants and refineries: rising film evaporators,

and distinct falling film models for beet and cane sugar.

With more than 500 units sold, Fives Cail evaporators are

acknowledged for their excellent heat-exchange performance,

minimal colour increase and entrainment.

Rising film evaporators Improved climbing performance

Very clear improvement of heat exchange by steam Injection in the juice: installation of aspecific ejector

Juice colour increase Minimal colour increase thanks to short retention time

Juice distribution Patented designs specifically adapted for cane and beet applications Uniform distribution of juice Low ∆T on all juices (high or low brix) Option: double juice circulation

Heat exchange performance Excellent heat exchange: optimal steam distribution Consistent steam circulation by recovery of non-condensable circulation gases at the center of the calandriaLow rate of tube fouling

Calandria reliability An integrated skirt ensures mechanical protection of the calandria Calandrias available in various materials: carbon steel, stainless(ferritic or austenitic)
