[0021] The beneficial effects of the above technical solution are: The extraction device is used to extract licorice residue raw material (the moisture content of licorice residue is about 5%) to obtain an extract. The specific steps are as follows: a certain weight portion of licorice residue raw material is put into the extraction chamber 201, and then a certain weight portion of methanol and ethyl acetate are added to the extraction chamber 201, wherein the weight portion ratio of the licorice residue raw material, methanol and ethyl acetate is 5:1:19. After soaking for 30 minutes, the stirring mechanism 1 is turned on. After stirring for 2.5 hours, the feeding pump 7 is controlled to work, and the solution in the extraction chamber 201 is filtered through the filter screen 1 and then sent to the extraction chamber 201 through the transmission pipe 8. into the impurity removal chamber 4 in the impurity removal and adsorption integrated device, and then add a certain weight portion of a mixed solution of methanol and ethyl acetate to the extraction chamber 201 again, the weight portion ratio of the methanol added this time to the methanol added for the first time is 3:20, and the weight portion ratio of the ethyl acetate added this time to the ethyl acetate added for the first time is 14.25:19, and the stirring mechanism is controlled to work for 2 hours again, and the solution in the extraction chamber 201 is filtered again through the filter screen, and sent to the impurity removal chamber 4 in the impurity removal and adsorption integrated device through the transmission pipe 8, and the two extracts are mixed; Then, the mixed liquid is first concentrated in the impurity removal chamber 4. When the volume of the concentrated liquid is reduced to 40%-60% of the liquid before concentration, pure water is gradually added to the remaining concentrated liquid, and the concentration is continued. The volume of the pure water added is 70%-90% of the total volume of the concentrated liquid before concentration. During the concentration process, the solvent in the concentrated liquid is discharged from the impurity removal chamber 4 and recovered. Then, the concentrated liquid is filtered and discharged from the impurity removal chamber 4 while hot. The concentrated liquid is impurities, and the remaining solids continue to be in the impurity removal chamber 4. Then, a certain weight of pure water is added to the impurity removal chamber 4. The pure water and the impurity removal chamber 4 are mixed. The weight ratio of the solid in the chamber 4 is 8:1, and the temperature is raised to maintain at 50°C, and then a 5% NaOH solution is added to the impurity removal chamber 4 until the pH value of the liquid in the impurity removal chamber 4 is controlled at 10, and the addition of the NaOH solution is stopped. After the stirring mechanism 2 is controlled to work for 1 hour, the stirring mechanism 2 is stopped, and the temperature is allowed to stand for 2 hours to cool down. The obtained solution is filtered and discharged into the impurity removal adsorption chamber 5. While the stirring mechanism 2 is controlled to work, a 5% HCl solution is added to the impurity removal adsorption chamber 5. After the pH value of the solution in the impurity removal adsorption chamber 5 reaches 1, the addition of the HCl solution is stopped, and the stirring mechanism 2 is continued to work for 1 hour. The stirring mechanism 2 is stopped, and the liquid is allowed to stand for 1 hour, and the liquid is discharged from the impurity removal adsorption chamber 5; A certain amount of 85% ethanol is added to the impurity removal adsorption chamber 5, and the solids remaining in the impurity removal adsorption chamber 5 are completely dissolved with the 85% ethanol, wherein the weight ratio of the added 85% ethanol to the solids remaining in the impurity removal adsorption chamber 5 is 1.5:1, and finally pure water is added, and the weight ratio of the added pure water to the 85% ethanol is 7.5:1, and finally the mixed solution is discharged from the impurity removal adsorption chamber 5 and passed through a macroporous adsorption resin, and after the resin is saturated with adsorption, it is washed with clean water, and then desorbed with a 60% ethanol solvent to elute the glabridin adsorbed on the resin, and the desorbed liquid is concentrated and dried to obtain a glabridin solid powder; In the above-mentioned extraction and separation process of glabridin, multiple stirring, multiple filtering, multiple heating concentration and adsorption drying processes are integrated into the extraction equipment and the impurity removal and adsorption integrated equipment, which not only reduces the installation space required for too many equipment, but also reduces the manpower and time consumption for transferring materials generated in each process, facilitates the operation of the staff, improves the extraction and separation efficiency of glabridin, and solves the problem that multiple stirring, multiple filtering, multiple heating concentration and adsorption drying processes are required in the process of obtaining glabridin. If corresponding equipment is set for each process, it will not only occupy a large space volume, but also need to transfer the materials generated in each process, which increases the cumbersomeness of the staff's operation, wastes time and effort, and reduces the technical problem of the extraction and separation efficiency of glabridin.

The stirring rod 202 is evenly spaced with a plurality of stirring blades 203 along the up and down directions. The stirring rod 202 passes through the upper end of the extraction chamber 201 and is fixedly connected to an external motor 6, which is fixedly arranged in the middle of the upper end of the extraction shell 2.

[0023] The beneficial effects of the above technical solution are: When the stirring mechanism is working, the motor 6 is controlled to work, the motor 6 drives the stirring rod 202 to rotate, the stirring rod 202 drives the stirring blade 203 to rotate, and the stirring blade 203 can stir and mix the materials in the extraction chamber 201 when it rotates.

The distance sensor 103 detects the distance between the lower end of the bottom plate 104 and the lower end of the bottom shell 1, so as to obtain the movement amount of the bottom plate 104. According to the stiffness coefficient of the spring damping rod 102, the elastic force change value of the spring damping rod 102 can be obtained, thereby obtaining the gravity of the material added to the extraction chamber 201. According to the preset movement amount of the bottom plate 104, materials are added in sequence. Specifically, when adding licorice residue raw material, methanol and ethyl acetate, the corresponding movement amount of the bottom plate 104 is set in sequence according to their weight ratio. After the movement amount of the bottom plate 104 reaches the movement amount corresponding to the weight of the licorice residue raw material, the addition of the licorice residue raw material is stopped and methanol is started. After the bottom plate 104 continues to move and its movement amount reaches the movement amount corresponding to the weight of methanol, the addition of methanol is stopped and ethyl acetate is started. After the movement amount of the bottom plate 104 reaches the movement amount corresponding to the weight of ethyl acetate, the feeding step is completed. The setting of the distance sensor 103 and the plurality of spring damping rods 102 facilitates the precise control of the material addition amount added to the extraction chamber 201, which is beneficial to improving the extraction effect and avoiding waste of materials.

The ratio is the weight ratio of methanol and ethyl acetate, that is, the ratio of the distance from the middle of the feed shell 1 224 to the center of the rotating shaft 219 along the horizontal direction to the distance from the middle of the feed shell 213 to the center of the rotating shaft 219 along the horizontal direction is 1:19. The balance block 218 is regarded as a balance bar, so that the torques on the left and right sides of the balance block 218 are the same, so it is only necessary to ensure that the balance block 218 reaches a balanced state, that is, after the matching shaft 223 moves to the corresponding position of the movable groove, the limit plate 211 and the plurality of springs 210 return to their original positions, and the weight ratio of methanol and ethyl acetate reaches the target ratio. At this time, under the action of gravity, the operating block 222 drives the matching shaft 223 to slide downward along the movable groove, and the operating block 222 drives the connecting plate 217 to move downward.The connecting plate 217 drives the stopper 216 to disengage from the material hole. At the same time, since the limiting plate 211 and the plurality of springs 210 return to their original positions, the force acting on the block 209 is reduced, so that the connecting plate 217 can push the block 209 to separate from the feeding port 215, so that the methanol and ethyl acetate in the material chamber 214 flow into the extraction chamber 201. The setting of the feeding mechanism facilitates the accurate control of the weight ratio of methanol and ethyl acetate, and the setting of the feeding mechanism reduces the number of times the movement of the bottom plate 104 is monitored. By adjusting the horizontal spacing from the middle of the feeding shell 1 224 to the center of the rotating shaft 219 and the horizontal spacing from the middle of the feeding shell 213 to the center of the rotating shaft 219, two different liquid materials can be added according to the target weight ratio, which saves time and effort, does not need to be weighed, and can also reduce the number of monitoring the movement of the bottom plate 104 in Example 2. The feeding port 3 can also be provided with a feeding mechanism to facilitate the control of the amount of methanol and ethyl acetate added for the second time. Example 4

[0029] The beneficial effects of the above technical solution are: A certain amount of 85% ethanol is added to the impurity removal adsorption chamber 5 through the feed port 502 to completely dissolve the solids remaining in the impurity removal adsorption chamber 5 with the 85% ethanol. Finally, pure water is added through the feed port 502. Finally, the valve 3 507 is opened to discharge the mixed solution from the impurity removal adsorption chamber 5 and into the adsorption chamber 318. The impurities passing through the macroporous adsorption resin are collected in the collection shell 2 11 through the discharge port 5 304 and the bellows 3. In this process, glabridin is adsorbed by the macroporous adsorption resin. The weight of the grease gradually increases, driving the adsorption shell 303 to move downward, and the adsorption shell 303 drives the limiting annular block 302 to slide downward along the annular cavity 301. At the same time, in the process of the adsorption shell 303 moving downward, it contacts the inclined ends of the positioning block 2 322 and the positioning block 1 306, so that the positioning block 2 322 and the positioning block 1 306 move in a direction away from each other, and the positioning block 1 306 drives the baffle plate 2 307 and the sliding plate 1 308 to move, the spring 4 309 is compressed, and the positioning block 2 322 drives the spring 5 317 to compress until After the macroporous adsorption resin is saturated with adsorption, the limiting annular block 302 just contacts the contact switch at the bottom of the annular cavity 301, the baffle hole 305 and the baffle 307 are matched, and the convex movable port 319 just matches the baffle hole 312.

The contact switch controls the valve 3 507 to close automatically through the controller. When the springs 309 are always in a compressed state, the valve 307 is automatically closed. Under the elastic action of 314, the baffle plate 1 311 pushes the push block 320 into the convex movable port 319 through the guide wheel 315, so that the baffle plate 1 311 no longer blocks the discharge port 4 310, and then the clean water is introduced into the adsorption chamber 318 through the liquid inlet to wash the macroporous adsorption resin. The washed liquid is sent to the drying box 12 through the discharge port 4 310 and the bellows 2. At this time, the discharge port of the drying box 12 needs to be opened until the washing is completed, and then the discharge port of the drying box 12 is closed, and 60% of the liquid is sent through the liquid inlet.

The arrangement of the above-mentioned adsorption shell 303, the positioning block 1 306 and the positioning block 2 322 and their connecting parts can automatically determine whether the macroporous adsorption resin is saturated with adsorption, so as to avoid the waste caused by continuing to introduce the mixed solution containing glabridin in the impurity removal adsorption chamber 5 into the adsorption chamber 318 after the macroporous adsorption resin is saturated with adsorption. When the macroporous adsorption resin is desorbed and reused, the baffle 1 311 and the guide wheel 315 are pushed into the baffle hole 1 312 by the push block 320, so that the baffle 1 311 re-enters the discharge port 4 310, and then the sliding plate 1 308 is pulled to separate the baffle 2 307 from the discharge port 5 304, and the adsorption shell 303 is pushed to return to its original position.The arrangement of spring four 309 and spring five 317 plays a supporting role for the adsorption shell 303, and then the valve three 507 is opened, and the above steps are repeated.
