The side of the lower surface of the lower roasting and grinding chamber 3 is formed in a hole-free part 4 and many hot air through holes 5 are formed over whole circumference in an upper part than the intermediate. An agitating body 7 having an agitating wing 9 for jumping coffee beans up to the upper smoking chamber 12 is installed in the lower roasting and grinding chamber 3 and an earthen parching pan 22 for placing a seasoning member 17, e.g. charcoal wood, stone or seashell such as oyster shell or pearl shell for generating original taste when heated is detachably provided at nearly lower position of a roasting container 2 and a burner 25 is provided below the earthen parching pan 22 for placing.
