A 10% slurry of green tea being discharged from a Model 500 SCC after stripping of volatiles. The flow rate was 300 L/h. Several areas of SCC technology have been substantially expanded during the development of slurry processing applications. These include specialised CIP techniques and systems for controlling the flow pattern of high solids feed materials inside the column. The need to maintain the homogeneity of slurries in the column, particularly at the feed point, has led to the design and exhaustive testing of new mechanical arrangements. As a result, the processing of tea and coffee slurries is now routine on purpose-built SCC systems.
