CERAMIC MEMBRANES FOR CANE SUGAR JUICE CLARIFICATION

摘要

Ceramic membranes are increasingly being used in the sugar industry. Thanks to their unique thermal, chemical, and mechanical properties, ceramic membranes offer several advantages over polymeric membranes, stainless steel membranes, and conventional filtration techniques (e.g. rotary drum filtration, decantation, centrifugation, and media filtration). Ceramic membrane technology can be successfully employed at various sugar processing stages including clarification of raw juice during raw sugar production and clarification of raw/single-effect juice, upstream to chromatography or ion-exchange step, during refined sugar production. The presentation will highlight the ability of ceramic membranes to remove suspended/colloidal solids, reduce color, and increase sugar purity, making them a cost-effective and preferred method of filtration.
