What kind of valves are the most suitable ones for sugar industry? Sugar processing conditions are tough, requiring robustness, accuracy and reliability of the valves. The 'sugar' valves need to withstand continuous operation in high temperatures, and they need to handle erosive slurries fluids – not to mention the caustic and corrosive chemicals. Corrosion-resistant high performance valves provide high reliability and efficiency, leading to high uptime and very long service life. Valmet's valves are a cost effectiove solution for sugar processing.
Milling and extraction
The raw materials, sugarcane or sugar beet, are milled and then the sugar is extracted to produce a sugar-rich juice. Neles Wafer-Sphere™ butterfly valves keep your processes operating smoothly from start to finish, and deliver lower installed costs together with more up-time.
Filtration and chemical treatment
The juice is filtered and chemically treated to remove impurities. Valmet's range of high-performance valves are built to perform reliably in these tough conditions, which involve high temperatures and corrosive chemicals.
The juice is further refined with more filtering, clarification and evaporation. From here the sugar can either be crystalized for use as sugar or concentrated into molasses to ferment into ethanol. Valmet offers valves to handle all kinds of liquids, from viscous to volatile.
