Falling Film Evaporators
FFE plus Falling Film Evaporators
The efficiency of the sugar plants depends to a large extent on the performance of its evaporators. The conventional Robert evaporators used in the most of the cane sugar factories work with high ΔT thus usually 1st or 2nd vapours are required for heating/ boiling of juice/ massecuite. Robert and Kestner evaporators allow steam saving only down to a level of approx. 40% steam on cane. Blow this level, falling film evaporators become essential. Further, to target a steam demand of less than 32% on cane, it is a must to operate a complete falling film evaporation plant.
IPRO and IPROINDIA group is pioneer in introducing the Falling Film Evaporators in the cane sugar industry.
The first ever complete falling film evaporation plants in the cane sugar industry have been commissioned in India at Shree Renuka, Athani and in Pakistan at Almoiz, both in 2007 based on IPRO design. Both the plants achieved the best steam performance in their respective country and set benchmarks. Since this time, a boom of installations of falling film evaporators followed.
