[0050] The filter assembly 6 is connected to the bottom of the heating tank 1, and the top of the filter assembly 6 is sealed and rotated with the output end of the rotating assembly 3.

[0051] The filter assembly 6 includes a fixed disk 61 and a movable ring 62. The fixed disk 61 is fixedly connected to the bottom of the heating tank 1 and is sealed and rotatably connected to the bottom of the rotating cylinder 33. A plurality of liquid outlet holes 611 are penetrated through the fixed disk 61. The outer side of the movable ring 62 is sealed and slidably connected to the bottom of the heating tank 1. A plurality of first electric telescopic rods 65 are installed at the bottom of the heating tank 1.

A plurality of sealing plugs 63 are fixedly connected to the movable ring 62. After the plurality of sealing plugs 63 move upward, they are sealed and slidably matched with the plurality of liquid outlet holes 611 one by one. The bottom of the movable ring 62 is connected to a funnel-shaped filter plate 64. One side of the heating tank 1 is connected to a vacuum pump 2 through a connecting pipe, wherein the connecting pipe is connected to the bottom of the fixed disk 61 in the heating tank 1.

[0052] The liquid outlet 7 is connected to the bottom of the heating tank 1. The liquid outlet 7 includes a liquid outlet pipe connected to the bottom of the heating tank 1 and a valve installed on the liquid outlet pipe to facilitate the control of the outflow of the extraction liquid.

[0053] In the present invention, ethanol and licorice powder are added into the interior of the heating tank 1 through the opened connecting portion 42, and then the connecting portions 42 of multiple groups are closed;

[0054] Then, the first motor 32 is started, and the output end of the first motor 32 rotates through the rotating cylinder 33 to drive the stirring and shearing assembly 5 to rotate, so that the stirring frame 531 and the tooth plate 552 both rotate inside the heating tank 1, thereby forming a stirring and mixing effect on the ethanol and licorice powder in the heating tank 1;

[0055] During this process, the heating component in the heating tank 1 works, so that the temperature of the mixed solution of ethanol and licorice powder increases, promoting the precipitation of the effective ingredients in the licorice powder;

[0056] At the same time, the second motor 511 is started, and its output end rotates to drive the screw rod 512 to rotate. Under the restriction of the rotating cylinder 33, the threaded block 513 moves vertically up and down along the screw rod 512. The transmission of the elastic connecting component 52 allows the stirring frame 531 and the tooth plate 552 to move up and down while rotating inside the heating tank 1, so that the solutions at different positions inside the heating tank 1 can be stirred by the stirring frame 531 and the tooth plate 552, so that the solutions can be quickly mixed and evenly mixed.

[0057] When the stirring frame 531 rotates, the motor 551 is started, and the two motors 551 cause the two sets of tooth plates 552 in the same stirring frame 531 to rotate in opposite directions, so that the two sets of embedded rings 522 are interlaced with each other during rotation, and the rotating tooth plates 552 are interlaced with the adjacent embedded strips 533, so that the licorice powder is sheared when passing through the gap between the tooth plates 552 and the embedded strips 533, which can not only reduce the agglomeration of particles and improve the mixing effect, but also promote the precipitation of effective ingredients in the licorice powder and improve the efficiency of separation and extraction;

[0058] After stirring for a period of time, the second motor 511 is controlled to drive the threaded block 513 and the blocking block 54 to move upward, so that the embedding groove 541 on the blocking block 54 matches the position of the embedding block 452, and then the second electric telescopic rod 451 is started, and its output end is extended to push the embedding block 452 to be embedded in the embedding groove 541 through the strip groove seal, and then the clamping part 43 is controlled to release the clamping of the rotating cylinder 33. At this time, the blocking block 54 moves with the threaded block 513 and can drive the filter plate 41 to move together, so that the filter plate 41 and the threaded block 513 are linked;

[0059] Then, the second motor 511 works to make the threaded block 513 drive the filter disc 41 to move downward for a distance. Since the solution can pass through the filter holes on the filter disc 41, the licorice powder residue will be gathered and squeezed between the filter disc 41 and the fixed disc 61. Before this, the moving ring 62 is pushed to the upper position by the output end of the first electric telescopic rod 65. The upper end of the sealing plug 63 on the moving ring 62 protrudes from the liquid outlet hole 611 to seal the liquid outlet hole 611, which can prevent the extract from leaking downward. The blocking block 54 can prevent the licorice powder residue from moving upward from the inside of the rotating cylinder 33.

[0060] Then, the rotating cylinder 33 rotates, so that the filter disc 41 and the stirring rod 44 continue to rotate, and the rotating stirring rod 44 can continuously stir the accumulated liquorice powder residue;

[0061] By controlling the output end of the first electric telescopic rod 65 to move slightly, the moving ring 62 and the sealing plug 63 move up and down slightly, that is, the sealing state of the sealing plug 63 and the liquid outlet 611 is maintained. When the multiple groups of sealing plugs 63 move up and down, the accumulated licorice powder residue can be squeezed. At the same time, the rotation of the two groups of tooth plates 552 can shear the licorice powder residue, so that the licorice powder residue can be continuously squeezed, stirred and sheared. On the one hand, the licorice powder residue can be stirred to improve the uniformity of the extrusion of the licorice powder residue, thereby promoting the further precipitation of the effective components in the licorice powder residue. On the other hand, the licorice powder residue can be prevented from agglomerating due to extrusion.

[0062] Since the connecting cylinder 523 can rotate on the outer surface of the fixed cylinder 521 to overcome the elastic force of the torsion spring 525, the stirring frame 531 can also rotate. When the sealing plug 63 moves up and down, the deflectable stirring frame 531 will not block the movement of the sealing plug 63.

[0063] After squeezing for a period of time, the second motor 511 is controlled to move the filter disc 41 upward, and the multiple groups of connecting parts 42 are opened, so that the solution can quickly pass through the filter disc 41, and then the agitation frame 531 and the tooth plate 552 are stirred to make the gathered licorice residues fully contact with ethanol again for extraction;

[0064] After the extraction is completed, the sealing plug 63 is separated from the fixed plate 61 by two groups of first electric telescopic rods 65, and the vacuum pump 2 is started at the same time, so that the extract can quickly pass through the multiple groups of liquid outlet holes 611 and fall onto the moving ring 62 and the funnel-shaped filter plate 64. The licorice powder residue can be filtered through the funnel-shaped filter plate 64, which promotes the filtration of the extract and improves the filtration efficiency.

[0065] The filtered extract can be discharged through the liquid outlet 7 .

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
