Good results can also be had by cooking the bread in a pre-heated Dutch oven with a well-fitting lid. Most expensive is a
Vacuum ceramic filter discharge due to reduced resistance and marginally lower cake moisture. Stage 2: Dewatering In rare cases, due to the even structure of the cakes formed, the steady flow profile of the ceramic filter media and the gas free filtrate flow cake, washing has proved to be efficient in ceramic disc filters. The formation of thicker cakes during filtration and higher vacuum level leads to greater removal of solute. Stage 3: Discharge The basic scraper works well when the cakes are relatively thick and non-sticky. The final cakes are discharged by blade or wire scrapers on either side of the discs
