There are several basic types of heat exchangers available, but for sanitary processing, scrape-surface heat exchangers are amongst the most popular. Scrape surface HEX (heat exchangers) are recommended for viscous products (greater than 1000 cps) and for challenging to process products. A scrape surface HEX is highly efficient and productive because of the system’s simplistic design. The HEX heats and cools continuously moving parts by allowing for a large heat transfer surface in only a small, confined space. Scrape surface HEX is generally used for the cooling and heating of high-viscosity products. This includes products with:

  • Particulates
  • Aseptic processes
  • Evaporation
  • High-fouling applications
  • Crystallization processes

Heat exchanges serve multiple functions depending on the industry that is used by the tool. Many advantages can be found when using a scrape surface HEX. These benefits include:

  1. Scraping is economical and clean
  2. Consistent homogeneity during the mixing processes
  3. Cooling and Heating for products that have firm components
  4. Complete and thorough cleaning
  5. Low downtime
  6. Constant temperature
  7. Compatible capacity

Because of the benefits, scrape surface heat exchangers serve in many different applications. They are used when processing package food, and they are used for industrial refrigerations. They are consistently found in the biotechnology field, as well as within agricultural processing.

    Dynamic Scraped Surface Heat ExchangerSCRAPED 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 scrape the inner wall of the inner pipe, allowing for continuous stable heat transfer by removing the film or crystals from the heat transfer surface. Overall heat transfer is improved by the scraping action.
