APP Jingui BM2: Moving towards a low-carbon operation
In 2021, APP Group successfully started up their new Jingui BM2 machine. The Valmet-supplied technology used in BM2 helps the company meet its goals for low-carbon operations. Part of the delivery was an Enzymatic Starch Cooking ZE unit.
The starch cooking system in the CCK workshop adopts the new integrated technology to collect waste heat from the cooking process for heating fresh water. Recycling hot water is in line with our targets for low carbon operations. The integrated design improves our field installation efficiency. It covers a smaller and more compact area than before, and the operation is easy to master.”
