Patent abstract
A curved scraper blade for a scraped-surface heat exchanger pivots about an axis off the centerline of the blade. The profile of the blade is chosen to provide a low initial scrape angle and to change gradually if at all as the blade wears away in service. The off-center pivot placement allows scraped material to flow between the blade and the drive shaft. Several materials are suitable for the blade, including PEEK thermoplastic.
