D-1525 IMPROVED SCRAPED-SURFACE APPARATUS Abstract of the Disclosure Scraped-surface heat exchangers and similar apparatus employing scraper blades hinged to a shaft so as to scrape a fluid being processed from an elongated cylindrical wall are improved so as to obviate any need either for separate bear- ings at opposite ends of the shaft or for special skids to be used in disassembly and reassembly and so as to allow the blades to be biased against the wall without separate springs. Each blade bears on the wall not only at its lead- ing or scraping edge but also at a trailing or bearing surface, so as to center the shaft and facilitate its rotation, so as to hold the edge in uniform relation to the wall, and so as to bias the edge of the blade against the wall.
