Components

A brewing system for every need. Make a coffee the traditional way with paper filter with the FilterFresh® system or create freshbrew coffee and real Espresso with the one brewer CoEx® with its patented pressure switch.

  CoEx®

CoEx® is a unique brewer, developed and patented by de Jong DUKE. It is the only brewer in the world that allows you to make two distinctly different coffees, with just one machine;

  • Fresh brew coffee, at 1-8 bar pressure

We use a Uni-Brewer that makes each cup of coffee fresh through it's unique filterfresh® vacuum principle. To ensure a clean cup of coffee, the system uses filterpaper. For fresh brew coffee a (paper)filter system gives you the best quality.


The process

The brewer operates according to the vacuum principle. Grinded coffee is dosed into the brewer chamber, together with the hot water. Then the brewer motor turns, moving the piston up. By this movement, the water and coffee are mixed, improving the extraction. Consequently, less ground coffee is necessary to obtain stronger and more flavoured coffee. Subsequently, the piston moves down, pulling the coffee through the filter paper. The coffee flows out of the cylinder via the outflow into the cup. The filter paper, together with the coffee residue, is transported by means of the transport wheels, when the piston is in the almost lower position and the brewer chamber is lifted. After this, the brewer returns to the rest mode and is ready for the next cycle.
