The dynamic scraped surface heat exchangers incorporate an internal mechanism which periodically removes the product from the heat transfer wall. The product side is scraped by blades attached to a moving shaft or frame. The blades are made of a rigid plastic material to prevent damage to the scraped surface.
Another type of heat exchanger is called "(dynamic) scraped surface heat exchanger". This is mainly used for heating or cooling with high-viscosity products, crystallization processes, evaporation and high-fouling applications. Long running times are achieved due to the continuous scraping of the surface, thus avoiding fouling and achieving a ...
A regenerative thermal oxidizer (RTO) is an example of a waste heat recovery unit that utilizes a regenerative process.. A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.

The idea is to use a well-polished evaporator surface (dynamic scraped surface heat exchanger) and appropriate mechanisms to prevent tubing from adhering to the ice embryos, and to prevent growth and a thickening of the ice on the inside cooling surface. A whip rod, screw, or shaft with metallic or plastic wipers is usually used as a mechanism ...
In some heat-transfer applications, mechanical mitigation with dynamic scraped surface heat exchangers is an option. Also ultrasonic or abrasive cleaning methods are available for many specific applications.
In indirect systems, the product is heated by a solid heat exchanger similar to those used for pasteurization. However, as higher temperatures are applied, it is necessary to employ higher pressures in order to prevent boiling. [14] There are three types of exchangers in use: [15] Plate exchangers, Tubular exchangers; Scraped-surface exchangers.
The flow conditions in many industrial equipment (such as pipes, ducts, precipitators, gas scrubbers, dynamic scraped surface heat exchangers, etc.) and machines (for instance, internal combustion engines and gas turbines). The external flow over all kinds of vehicles such as cars, airplanes, ships, and submarines.
