    Abstract: An equipment comprising a vibration part, a transmitting drum and vibration absorbers for extracting raw materials using ultrasonic waves is provided to extract the raw materials easily by obtaining a high yield and reducing an extraction time, and consume a low extraction cost by making it not necessary to perform an additional purification process. An equipment for extracting raw materials using ultrasonic waves comprises: an extraction tank(100) containing an extraction object and an extraction solvent; a vibration part(103) disposed to surround an outer part of the extraction tank; a transmitting drum(109) which is disposed such that the transmitting plate is spaced from the vibration part in a predetermined distance, and the extraction object is separated from the vibration part, and which transmits ultrasonic waves generated from the vibration part to the extraction object; and an ultrasonic wave-transmitting substance (107) filled in a space within the transmitting drum including the vibration part. The transmitting drum is a thin plate made of a material that is insert to the ultrasonic wave-transmitting substance or the extraction solvent. The equipment further comprises vibration absorbers(108) disposed on upper and lower portions of the transmitting drum, impellers(105) driven by an agitator(104), a baffle plate(106) installed in a lower part within the extraction tank, and an oscillation part(101) connected to the vibration part to generate ultrasonic waves.
