Summary:A method for roasting coffee beans comprising the steps of a) heating the coffee beans until the temperature of the coffee beans is at least 180°C; b) injecting a stream of oxygen-containing gas into the flow of hot air after the burner; and c) maintaining the injection of the stream of oxygen-containing gas until the end of the roasting process to mitigate the concentration of carbon monoxide in the roasting chamber, and wherein the coffee beans are roasted in a rotating fluidized bed roaster. L'invention concerne un procédé de torréfaction de grains de café comprenant les étapes consistant à a) chauffer les grains de café jusqu'à ce que la température des grains de café soit d'au moins 180 °C; b) injecter un flux de gaz contenant de l'oxygène dans le flux d'air chaud après le brûleur ; et c) maintenir l'injection du flux de gaz contenant de l'oxygène jusqu'à la fin du processus de torréfaction pour atténuer la concentration de monoxyde de carbone dans la chambre de torréfaction, et les grains de café étant torréfiés dans un torréfacteur à lit fluidisé rotatif.
