Cooking Kettle

Cooking kettles come in various sizes and can be used in a wide range of industries. Gpi Process Equipment is a manufacturer of stainless steel cooking kettles designed to fit your products and processes. Our cooking kettles start as small as 50 liter but can go up to 12.5m³.

For processes such as cooking and pasteurization, efficient heating of the tank is crucial and can be done various ways. Ensure the correct combination of heating capabilities and insulation of the tank in order to heat or cool your product within the desired time frame.  Let us know directly what heating capacity you require, and we will collaborate with you in order to arrive at the most efficient solution, whether this concerns a dimple, a double wall or a half pipe.

Finishing levels

As a standard, Gpi ensures a high-finishing level. For some applications, such as in the food industry or even in the pharmaceutical industry, specific requirements are applicable. As a standard, food tanks are produced with an internal roughness of Ra 0.8, but if desired we can also produce tanks with much smoother (and therefore more hygienic) inner walls.

Inline heating or cooling of viscous products

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.

“Gpi De Gouwe is not only a highly innovative company to work with,
but they also help you select the perfect process equipment.

Bas Jürgens, Protix

Models, options and products

The Kelstream is available in several sizes. In addition, there are several options to choose from. The Kelstreams are available as single units and also fully integrated. Get in contact to hear all the possibilities.

How a Scraped Surface Heat Exchanger works

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.

“Gpi did a magnificent job of producing fast, efficient
and user-friendly melting tanks in line with our requirements

Hans Zweers, Intersnack

Options and applications

The melting units are available in several sizes. Next to that we can offer different options. 
Get in contact to hear all the possibilities.

How a Melting Unit works

Unique melting grid design

Thanks to the special melting grid, manufactured on an automatic Tig/plasma welding bench, the product to be melted is constantly refreshed. In this way the temperature of the grid can be raised higher than on conventional melting units, without damaging (burning) delicate products. Due to the high heated surface, a high melting capacity is achieved on a minimal surface.

Customize to your wishes

We understand that a standard melting unit might not meet your wishes. That is why our melting trays can be equipped with a large number of options, so that we can be sure that the melting unit fits best with your product and process. 

As an example, we can include an extra melting plate in the design to guarantee fully melted product for difficult products. In addition, the collection container for molten product can also be equipped with a heating jacket.

Test the melting unit
with your own product

Gpi has melting units available for testing with your own product. This ensures you get a melting unit that works.
