The invention relates to the field of extracting, and specifically relates to a
supercritical fluid extracting device. The device comprises a fixing frame, a storing mechanism, a
barrel body, a driving mechanism, a mixing mechanism, a filtering mechanism, an extracting mechanism and a feeding port, wherein the mixing mechanism is mounted in the
barrel body and comprises injecting heads, an air
pipe, a rubber rod, a funnel and a compressing plate; the inner sidewall of the
barrel body is fixedly connected to the funnel; the top surface of the funnel is connected to the compressing plate throughthe elastic rubber rod; the top surface of the compressing plate is propped against the driving mechanism; the bottom end of the funnel is equipped with the air
pipe; the injecting heads which are distributed at equal intervals are arranged on the sidewall of the air
pipe; and the filtering mechanism is in thread connection with the bottom end of the barrel body. According to the device, air in the barrel body is compressed and blown into the materials and the
supercritical fluid, so that the dissolving rate of the materials in the
supercritical fluid is increased, and moreover, the temperature of the supercritical fluid does not increase.
