PURPOSE:To cause preserved coffee beans to generate an excellent aroma again and to amuse diversification of coffee by roasting by a method wherein a beam heating device is provided in a coffee bean storage chamber or a coffee bean crushing chamber. CONSTITUTION:A bean heating device 5 is mounted to the bottom part of a bean storage chamber 1, and the temperature of a bean heating device 5 is controlled by means of a temperature detector 6. By means of a switch panel 20, it is inputted by on ON and OFF key 21 whether additional roasting is effected, and the degree of toasting is inputted by a roasting degree UP and DOWN key 23. The number of cups for drinking coffee is inputted by a number of cups UP and DOWN key 24. When preparation is completed, a start key 22 is pressed. When additional roasting of beans is completed, a cutter 2 is rotated at a high speed to crush beans. The crushed beans are flied to the outside by means of a centrifugal force, and are forced to pass a porous plate 12 to convey them to an extracting part 10. Water in a water tank is guided to a water heating device 8 and fed through a hot water feed port 9 to the extracting part 10 to perform extraction of coffee. |
