Heat exchangers are machines used to transfer heat between two liquids. A scraped surface heat exchanger is a specific type of heat exchanger that has been designed to meet specific needs and address certain problems associated with other models of heat exchangers.
By removing fouling layers, preventing ice and other by-products from being generated, and increasing turbulence when faced with high viscosity flow, they are able to increase the transfer of heat.
They are designed to be suitable for products with varying viscosities and are often used in the food industry as they are able to effectively process products containing particulates like meat sauces.
It can be difficult to find information about specialist products like this on google, so it’s often worth searching directly on manufacturer websites.
