PURPOSE:To provide a ripening apparatus effective in accelerating the ripening of vinegar, etc., and composed of an electromagnetic wave antenna, an ultrasonic vibrator and a far infrared generation element placed on the inner wall of a tank or a pipe and a driving apparatus to drive the above devices in a continuous, intermittent or staggered mode. CONSTITUTION:Two or more devices selected from an electromagnetic wave antenna 3, an ultrasonic vibrator 4 and a far infrared generation element 5 are placed on the inner wall of a tank 1 and the devices are driven in continuous, intermittent or staggered mode with driving apparatuses 8, 9, 10. A ripening object such as rice wine or vinegar filled in the tank 1 is ripened in a short time by using the ripening apparatus having the above construction.
