Plate technology boosts capacity at sugar refinery

Indonesia's largest sugar refinery, PT Angels Products, boosted its capacity by installing a sugar evaporation system utilising plate technology from Alfa Laval. It includes three AlfaVap plate evaporators and an AlfaCond condenser.

Operation Director James R. Isman says: “I have good experience of Alfa Laval and we now have the most efficient, up-to-date evaporators on the market. We are the first sugar refinery in Indonesia to invest in this technology, and others are following.”

Located in Serang on the western side of Java, PT Angels Products imports raw sugar which is refined to produce different grades. The process consists of dissolving the raw sugar in hot water, various purification steps, evaporation of the water, crystallisation and drying. The plant has an output of 1,100 tons of refined sugar per day.

Customer's voice

The new system reduced steam consumption in the process by about 25%. “The residence time in the vacuum pans is shorter as well, from three to two hours. The AlfaVap evaporators work efficiently, and it has not been necessary to open them.
