Title (EN) A METHOD FOR THE CONTINUOUS PRODUCTION OF COFFEE EXTRACT
(FR) PROCEDE DE PRODUCTION CONTINUE D'EXTRAIT DE CAFE
Abstract:
(EN) The disclosure relates to a method of producing a high-quality coffee extract. The roasted coffee beans are positively fed into water and are ground in a colloid mill (10) during simultaneous mixing to form a coffee suspension. The coffee suspension is extracted in at least one decanter centrifuge (21) to form a liquid coffee extract of high quality. The coffee concentrate possibly passes through a filter (28) before being cooled in, for example, a plate heat exchanger (29). The system for carrying the method into effect is a closed system (32) from the infeed of the coffee beans into water, and until the finished coffee extract has been cooled.
(FR) L'invention concerne un procédé de production d'extrait de café de grande qualité. Les grains de café torréfiés sont envoyés dans l'eau, sont moulus dans un broyeur colloïdal (10) et mélangés simultanément de sorte qu'une suspension de café soit formée. La susupension de café est extraite dans au moins une centrifugeuse de décantation (21) de sorte qu'un extrait de café liquide de grande qualité soit formé. Le concentré de café passe éventuellement dans un filtre (28) avant d'être refroidi dans, par exemple, un échangeur thermique à plaques (29). Le système pour la mise en oeuvre dudit procédé est un système clos (32), depuis l'alimentation en grains de café dans de l'eau jusqu'au refroidissement de l'extrait de café fini.
