Double screw continuous reverse flow supersonic extractor

The utility model discloses a dual screw continuous countercurrent superaudiable soak distill device. The utility model is composed of a main device soak bin 1, superaudiable energy exchanging devices 22, a superaudiable power 23, a feed device 2, a residue discharge device 4, a filter 4, a condenser 5, a juice crushing device 6, and a dynamic drive device 7. The inclined arranged soak bin is provided with two reversal screw axes side by side inside; the soak bin outside wall is arranged with a plenty of superaudiable energy exchanging devices on the lower part forming an angle of 0-90 degrees with the level direction; the cavitating and wall-breaking effect of the superaudiable as well as the machine shaking effect can stably realize the continuous countercurrent soak process, maximally keep the energy difference of the dissolvable content between the inside and outside of the raw material, increase the total soak speed and efficiency, reduce the menstruum dosage, and decrease the liquid-out coefficient. The screw axis is composed of several sections with two connection points of two are alternate to connected with a bearing or an up frame of the soak bin to form a hanging brace. The soak bin has a large effective bulk and good effect of countercurrent distilling; and the superuadiable power and the frequency can be combined in many forms, which in particular breaks the length limitation sue to the gravity deflexion factor of the screw axis.
