Abstract

PURPOSE: After heated with mirowaves, raw coffee beans are roasted, thus effecting uniform heating and drying in a relatively short time to produce coffee beans showing good smell and taste when ground.
CONSTITUTION: Raw coffee beans are dried by irradiating with microwaves of higher than 300MHz to a level of 8W19%, preferably 12W15% water content. Then, they are roasted at a bean temperature of higher than about 140°C, preferably at about 180°C.
