[0002] Low temperature concentration and extraction equipment is usually used to extract the desired compounds or components from plants, animal tissues or other substances, while maintaining the activity and stability of these components as much as possible. These equipment usually operate under low temperature conditions to avoid degradation or loss of heat-sensitive substances.

[0003] During the use of existing concentration and extraction equipment, the required components are usually extracted by contacting the raw materials with the extraction solvent. The solvent will evaporate after the raw materials are extracted. Currently, the evaporated solvent is usually discharged directly, and the evaporated solvent cannot be recycled, resulting in a waste of resources and increased use costs. In addition, the extract will be mixed in the solvent, and the existing technology cannot quickly separate the extract from the solvent, affecting the extraction purity.

[0004] Therefore, it is necessary to provide a new high-efficiency low-temperature concentration extraction equipment to solve the above technical problems. Utility Model Content

Through the second filter plate 10, the solvent and the extract can be separated. A water tank 11 is provided on the top of the collection box 9. One side of the water tank 11 is connected by a pipeline to a water pump 12. The water outlet end of the water pump 12 is connected by a pipeline to a spray head 13. One end of the spray head 13 is connected to the top of the collection box 9 by a pipeline.

[0025] Refer to Figure 1 , Figure 2 and Figure 3As shown in the figure, a support frame 14 is fixedly connected to the outer side of the stirring cover 5. A guide rod 15 is slidably connected to the inner wall of the support frame 14. A limit block is provided at the top of the guide rod 15, and a convex block 16 is fixedly connected to the bottom of the guide rod 15. A spring 17 is arranged outside the guide rod 15. The rotation of the stirring cover 5 drives the support frame 14 to rotate, causing the convex block 16 to rotate and contact the first filter plate 4. The convex block 16 knocks on the first filter plate 4 to knock and dredge the first filter plate 4. The spring 17 buffers the convex block 16 to avoid the problem that the convex block 16 causes too much pressure on the first filter plate 4. The driving mechanism 7 includes a motor 71 fixed to the top of the cylinder body 2. The output end of the motor 71 is fixedly connected to a driving rod 72. The bottom of the driving rod 72 is fixedly connected to a connecting plate 73. The stirring cover 5 and the stirring head 6 are both fixed to the bottom of the connecting plate 73. Starting the motor 71 drives the driving rod 72 and the connecting plate 73 to rotate, driving the stirring cover 5 and the stirring head 6 to stir and mix the raw materials and the solvent, improving the extraction effect of the raw materials. A collecting pipe 18 is arranged outside the cylinder body 2 to collect the evaporated solvent through the collecting pipe 18. The solvent evaporated during extraction is recondensed back into a liquid state by the condenser body 8 for recycling. A recovery pipe 19 is arranged outside the condenser body 8, and the recovered solvent can be discharged through the recovery pipe 19. A vacuum pump 20 is arranged at the top of the cylinder body 2. During the extraction process, the vacuum pump 20 can reduce the boiling point of the solvent by reducing the pressure, promoting the volatilization and extraction of the solvent. A feed inlet 21 is arranged outside the cylinder body 2. A pumping pump 22 is arranged on the top of the bottom plate 1. The feed end of the pumping pump 22 is connected to the outside of the cylinder body 2 through a pipeline. One end of the pumping pump 22 is provided with a discharge pipe 23, and one end of the discharge pipe 23 is connected to the top of the collecting box 9.

[0026] Reference Figure 1 and Figure 4 As shown in the figure, a mounting plate 24 is fixedly connected to the top of the second filter plate 10. A limiting rod 25 is fixedly connected to one side of the mounting plate 24. A scraping plate 26 is slidably connected to the outside of the limiting rod 25. Pull the scraping plate 26 to slide outside the limiting rod 25, so that the scraping plate 26 pushes out the extract on the second filter plate 10, facilitating the taking out of the extract and scraping off the extract adhered to the second filter plate 10. A box door 27 is arranged on one side of the collecting box 9, and a discharge port 28 is arranged outside the collecting box 9.

[0027] Working principle: When this device is in use, raw materials and solvents are poured into the interior of the cylinder body 2 through the feed port 21. The air compressor 3 compresses gas at low temperature and then rapidly expands it to condense it into a liquid, thereby achieving the concentration and purification of substances. The motor 71 is started to drive the drive rod 72 and the connecting plate 73 to rotate, driving the stirring cover 5 and the stirring head 6 to stir and mix the raw materials and solvents, improving the extraction effect of the raw materials. The rotation of the stirring cover 5 drives the support frame 14 to rotate, causing the convex block 16 to rotate and contact the first filter plate 4. The convex block 16 knocks on the first filter plate 4 to dredge it. The spring 17 buffers the convex block 16 to avoid the problem that the convex block 16 exerts too much pressure on the first filter plate 4. The evaporated solvent is collected through the collection pipe 18. The condenser body 8 condenses the solvent evaporated during extraction back into a liquid state for recycling. During extraction, the vacuum pump 20 can reduce the boiling point of the solvent through decompression, promoting the volatilization and extraction of the solvent. The raw materials can be filtered through the first filter plate 4, causing the solvent and the extract to fall to the bottom of the cylinder body 2. The pumping pump 22 is started to pump the solvent and the extract into the collection box 9. The solvent and the extract can be separated through the second filter plate 10. The scraper 26 is pulled to slide outside the limiting rod 25, causing the scraper 26 to push out the extract on the second filter plate 10, facilitating the removal of the extract and scraping off the extract adhering to the second filter plate 10. The second filter plate 10 can be conveniently cleaned through the nozzle 13.
