Filtration is a key component in processing sugar beets into usable components. Our filters are used in many steps in the process, such as water filtration, mud-dewatering and juice clarification. Our filters are also used in the desugaring of molasses by both the Steffen process and the chromatographic processes.
Durco Filters Pressure Nutsches are ideal for piloting of new or modified batch operation and/or processes requiring recovery of process solids as dry or wet cake. They have the following benefits:
Easy recovery of cake in dry or wet form
Wide variety of construction materials
Available with alloy or rubber-lined vessels
No wasted heel (zero bypass)
Designs from full vacuum to 300 psi (20.68 bar) or higher
Wide variety of flow rates and solids loadings
Applications where cakes can build to several inches
Further treatment with nitrogen purges or washes (acids)
Permits multiple processes to take place within the filter such as steaming, sparging, drying or washing

High-fructose corn syrup comprises any of a group of corn syrups that has undergone enzymatic processing to convert some of its glucose into fructose to produce a desired sweetness. It has become very common in processed foods and beverages including breads, cereals, breakfast bars, lunch meats, yogurts, soups, and condiments. Our filters remove contaminants resulting in a pure and visibly clear product.
Filtration is a key process step in the edible/vegetable oil industry. Durco
Filters Pressure Leaf Filter and Filter Press products remove waxes, gums, slimes and gels that are present in applications.
Filtration of other oils: peanut, soya, sunflower, fish, olive
Crude oil filtration
Gum prefiltration prior to lecithin process
