For melting chocolate, fat and powders
Industrial Melting Unit
For inline- or batch melting of products, Gpi designs and produces industrial melting vats. The melting unit is capable to melt 100 up to 6000kg/h of various products. Think not only of chocolate, blocks of fat, margarine and butter, but also of powders and pellets.
The melting units range from 0.5m² up to 15m² of melting surface.
See the possible options and applications below.
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.

Standard cooking kettles or tailor made for your product and process
We understand that every cooking kettle is different. Therefor we design our kettles tailormade for you, so you can be sure that the tank will suit to your product and process best. Options we can include into your tank are:
- Fully integrated control panel
- Level switches
- Cleaning options
- Skid mounted
Agitator design and fabrication
In addition to tanks, Gpi De Gouwe also makes its own agitators. This way you have one point of contact for the entire tank concept. Agitators that we design and produce are:
- Anchor agitator
- Gate agitator
- Combination of agitators
- High shear mixers
- Turbo mixers
- Side entry agitators
- Static mixers
- External homogenizer
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. “
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
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.
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.
