The new IceCon® plant from Dan Kaffe has a pre-cooling system that cools down the coffee extract before it enters the freeze concentrator, maximizing ice production capacity.
Also, the number of moving parts has been reduced, making the new plant easier to operate, lighter to maintain and energy efficient since it consumes 50% less energy in comparison with the old plant. All of this translates in a significative operative cost reduction.

Managing Director at Dan Kaffe
In September 2023 the installation started with remote support from the GEA Freeze Concentration team in The Netherlands and since Dan Kaffe didn’t want to compromise their production schedule, most of the installation and commissioning of the new IceCon® plant was done while the old plant was still running. The time dedicated to connecting the new plant and shutting down the old one was kept to a minimum thanks to a carefully crafted installation & commissioning schedule.
All in all, the operation was a success and the production output targets as well as the concentration levels were met while plant downtime was very limited. Dan Kaffe will go on delivering the best premium quality with the help of GEA IceCon®.
The joint story of GEA & Dan Kaffe goes a long way back and we are proud for Dan Kaffe’s new and bespoke IceCon® plant to join other GEA equipment behind their production of prime quality coffee products.
GEA and Dan Kaffe – the ideal partnership behind prime quality coffee products.
After the extraction process, the low concentration coffee extract enters the pre-cooler of the freeze concentration system and gets cooled down to +4ºC then enters the IceCon® crystallizer. The outside jacket of the crystallizer is actively cooled, reducing the temperature of the coffee to its freezing point – hence, water will be converted into pure ice crystals. The mixture of coffee + ice crystals is fed into the wash columns, where the ice crystals are efficiently separated. Heat of the refrigeration system is used for melting the ice crystals, eliminating steam consumption.
As the removed water is replaced by fresh coffee extract, the concentration will increase.
Thanks to the low temperature processing and highly efficient removal of pure ice crystals, all nice coffee aromas are maintained in the concentrate -a trait that sets freeze concentration apart from other concentration technologies.
Here is to many more years of good coffee and partnership with Dan Kaffe.
