Scraped Surface Heat Exchanger

The Kelstream Scraped Surface Heat Exchanger is a vertical scraped heat exchanger with double concentric heated surfaces for an optimal heat exchange for food, feed, pharma and non-food.

This unique design in thermal processing brings all the benefits of different types heat exchangers together in one package: it can handle high viscous products like mashed potato, it has a large heated surface per unit, it takes only a small footprint and it doesn’t damage your product.

How a Scraped Surface Heat Exchanger works

Scraped Surface Heat Exchanger - render

Continuously scraped

The Kelstream continuously scrapes the whole heated or cooled surface, resulting in an extremely efficient heattransfer. This scraping principle has a major efficiency advantage compared to conventional plate or tube-shaped heat exchangers. In addition the scrapers prevent product contamination on the wall.

Two heat transfer surfaces

The Kelstream has two heat transfer surfaces. The heating or cooling media is fully separated from the product area.

Media which can be used are: glycol, icewater, water, liquid ammonia, steam or hot water.

Heating or cooling products with solid components

With the Kelstream Scraped Surface Heat Exchanger you can cool and heat products that contain firm components, with a maximum size of 25mm. Product identity is preserved in this process.

CIP cleanable​

The Kelstream Scraped Surface Heat  Exchanger can be fully included in the existing CIP system. You can clean the Kelstream counterlow, whereby the scraping system can rotate clockwise or anticlockwise. This results in optimum cleaning of the Kelstream.

Patented cartridge seal

The Kelstream is equipped with a hygienic lipseal. This lipseal does not require a barrier fluid to function. When the product or process requires a different type of seal, there is also a choice of a single or double mechanical seal with various barrier fluids.
