Scraped surface heat exchangers

With a large variety, it is likely you purchase your scraped surface heat exchanger from Foeth!

Scraping heat exchangers are widely used in the pharmaceutical and cosmetic industry for, for instance, piecemeal creams. In the food industry, this heat exchanger is used as a standard for the production of, for example, sauces, baby food, and dairy. These process machines are specifically designed for handling viscous or sticky products and are very versatile. Our stock is regularly supplied with models from specialized brands such as Deutsche Vacuumapparate, Alfa Laval, or APV.

What are scraped surface heat exchangers?

Scraped surface heat exchangers consist of a double casing and a stirrer with scraper blades. The outer shell is heated or cooled by a liquid, the product to be heated or cooled is mixed in the tube. The scraper heat exchanger is suitable for viscous products, with the scraper blades on the agitator keeping the inner wall clean. The vertical scraping heat exchanger "terlotherm" uses a tangential inlet and mixing space for maintaining product quality. The product is heated or cooled via concentric heat transfer surfaces of two. Because the product is scraped continuously from the walls, there is no burning or freezing.

The main advantages of agitation and scraping are as follows:

  • Clean inner wall due to continuous scraping.

  • Thermal efficiency with the elimination of the low-conductivity layer adhering to the wall.

  • Preservation of product quality by preventing localized burns or freezing.

  • Enhanced mixing efficiency.

  • Reduction of pressure drop in the exchanger.

Types of scraped surface heat exchangers and applications:

Scraped surface heat exchangers exist in horizontal or vertical configurations. The central tube can be concentric (agitator shaft in the center of the tube, constant wall thickness), eccentric (agitator shaft offset from the center of the tube, variable wall thickness), or oval.

Eccentric tubes are suitable for moderately viscous products. They introduce variability in heat exchange, with higher exchanges occurring where the wall is the thinnest. Mass rotation of the product and mechanical thermal loads are reduced, favoring mixing and thermal efficiency.

Oval-shaped tubes have even higher performance and are suitable for highly viscous, sticky, or fouling products. They also balance internal forces, preventing any deviation of the shaft.

The scrapers can be made of stainless steel (316), copper, or heat-resistant plastic (PEEK). The "Terlotherm" vertical scraped surface heat exchanger uses a tangential inlet and a mixing space to maintain product quality.

Scraped surface heat exchangers are widely used in the pharmaceutical, cosmetic, and food industries. They are involved in processes such as heating, cooling, pasteurization, sterilization, crystallization, gelatinization, freezing, evaporation, and more. They are used, among others, in the production of sauces, baby food, dairy products, concentrates, chocolate, margarine, pastry butter, caramel, soups, and jelly.
