Definitions

  • the present invention relates to food processing, and particularly to a method and device for processing unroasted beans and a coffee maker.
  • Coffee beans are taken from a living plant and contain both volatile oils and many anti-oxidant elements.
  • the volatile oils will give coffee its characteristic flavor with a roasting process.
  • the roasting process will also make the anti-oxidant elements (which are healthy ingredients for human beings) loss, such as Chlorogenic Acid that green coffee beans contains the most of it than other plants.
  • the first one is that, pre-heating the green coffee beans shortly before grinding will reduce greatly the required cutting force and make the grinding more easily. For example, cutting green coffee beans directly requires 16kg force, meanwhile the cutting force could be significantly reduced when the green coffee beans are shortly heated. With a heating temperature of 180* , the required cutting force is reduced by 4 times, dropping from 16kg to about 4kg after the green coffee beans are heated about 1 minute, and dropping to 2kg after the green coffee beans are heated about 2 minutes. For roasted beans, the cutting force is about 1.5- 2kg. And then it only needs small or even no modification to the current grinder in a coffee maker to make it suitable to grind the green coffee beans.
  • the second one is that, the contents of key nutrients of coffee beans vary against heating time. Typically, the content of, for example, a specific healthy ingredient such as the Chlorogenic Acid in the heated coffee beans increases shortly and then decreases as the heating duration increases.

  • the heating processing may be controlled by different kinds of parameters and thus the heating process can be controlled more effectively.

Abstract

L'invention se rapporte à un procédé de transformation de grains non torréfiés. Le procédé comprend les étapes consistant à chauffer les grains non torréfiés ; et à broyer les grains non torréfiés chauffés. La présente invention se rapporte également à un dispositif destiné à transformer les grains de café non torréfiés et à une machine à café utilisant le procédé décrit ci-dessus. Grâce à l'utilisation des procédés, dispositif ou machine à café précités, les grains de café bruts peuvent être d'abord chauffés pendant une certaine durée, et les grains de café bruts chauffés sont alors plus friables et peuvent être broyés plus facilement. Grâce à un mélange avec les grains torréfiés, du café contenant des ingrédients plus sains et ayant un bon goût peut être proposé aux consommateurs.
