Statement 1: Scraping improves heat transfer co-efficient by 5 times in case of non-Newtonian fluids. Statement 2: In food industry, major physical changes to food items when they’re processed, take place like transformation from Newtonian to Non-Newtonian fluids. Hence, scraped surface heat exchangers are very beneficial.
