Abstract
The residual material in a filter-dryer (1) is removed from the screen (15) by careful scraping with a lasso like belt (20). The scraped material will be removed through a side opening (16). To gain this remaining material adds to the yield of the process by reducing loss of product, and does not endanger personnel unnecessarily and therefore save process costs.
