Dynamic scraped surface heat exchanger
open-in-new
<p>The dynamic scraped surface heat exchanger (DSSHE) is a type of <a href="/facts/Heat_exchanger/CUzlMnBG">heat exchanger</a> used to remove or add heat to fluids, mainly foodstuffs, but also other industrial products. They have been designed to address specific problems that impede efficient heat transfer. DSSHEs improve efficiency by removing <a href="/facts/Fouling/4UxQP5Wk">fouling</a> layers, increasing <a href="/facts/Turbulence/NpgFUhG5">turbulence</a> in the case of high <a href="/facts/Viscosity/QLVfrdCz">viscosity</a> flow, and avoiding the generation of crystals and other process by-products. DSSHEs incorporate an internal mechanism which periodically removes the product from the heat transfer wall. The sides are scraped by blades made of a rigid plastic material to prevent damage to the scraped surface. </p>
