Scraped Surface Heat Exchangers (SSHE) are designed to overcome process problems encountered when processing viscous fluids. During some processes, shell and tube or plate and frame heat exchangers can foul and need to be taken out of service due to reduced heat transfer capacity. SSHE, on the other hand, continually scrapes the inner wall of the inner pipe, allowing for continuous and stable heat transfer by removing the film or crystals from the heat transfer surface. Overall, heat transfer is improved by the scraping action.
Margarine is similar in taste and appearance to butter but possesses several distinct differences. Margarine was developed as a substitute for butter. By the 19th century, butter had become a common staple in the diet of people who lived off the land, but was expensive for those who did not. Louis N
