Kelstream
Inline heating or cooling of viscous products
- Complete surface is continuously scraped to prevent burn-on or product build-up
- Two heat transfer surfaces in one machine for highly efficient heat transfer
- Hygienic lipseal solution
- Big heat transfer surface on a small footprint
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.
Options and Applications
The Kelstream is available in several sizes. Next to that we can offer different options.

How it works
Continuously scraped
The scraper system 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. Furthermore, this prevents the product from sticking to the surface.
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. The maximum product identity is preserved. You can cool/heat products with particles of a maximum size of 25 mm.
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.
Hygienic lipseal
The Kelstream is equipped with a hygienic lipseal. With this lipseal, you don’t need a barrier fluid to keep the seal working. But, when a hygienic solution is required, you can flush or clean the seal from within.
This prevents microbiological build-up or crystallization. The lipseal is cost effective, since you only need to replace the wearing parts of the seal.
