  • Blade cleaner for a continuous loop blade on a food slicing machine
    Patent number: 6968764
    Abstract: A cleaning device for a continuous loop band blade food processing machine. A pair of scrapers is positioned on, and seated against, opposite sides of the blade for scraping matter from the blade as it passes between the scrapers. The scrapers are biased against the blade. The upper scraper has an axis that is transverse to the blade's axis, and the blade can be removed by loosening the screw attaching the upper scraper and pivoting the scraper about the screw. The edge of the upper scraper is transverse to the blade's axis to cause scraped matter to flow toward a deflector panel that guides air and scraped matter into a vacuum inlet which is positioned near the edges of each scraper.
