Description

Technical Field

[0001] This utility model relates to the field of propolis extraction technology, and in particular to a supercritical extraction device. Background Technology

[0002] Propolis is a substance formed by bees collecting plant resins and mixing them with their secretions. It has excellent natural antibacterial, antioxidant, and anti-inflammatory functions. Studies have also found that propolis has significant effects on fighting tumors and regulating blood lipids and blood sugar. However, during the production process, propolis is often mixed with a lot of impurities. These substances often have no obvious medicinal value and may even be biologically toxic. Therefore, when using propolis, it is often necessary to extract it to achieve high-quality application of propolis products.

[0003] Currently, the mainstream extraction processes for propolis products are maceration and supercritical carbon dioxide extraction. However, maceration extraction is limited by the type of solvent, resulting in inconsistent extraction effects on different components of propolis and failing to fully utilize the propolis. Supercritical carbon dioxide extraction, on the other hand, has the advantage of being green and environmentally friendly. In supercritical carbon dioxide extraction, carbon dioxide is pressurized and heated to become liquid, and then introduced into the extraction tank to mix with the propolis. The mixture then flows through a pipe into a separation tank, where the carbon dioxide turns back into gas and is discharged. What remains is the extracted propolis.

[0004] However, when liquid carbon dioxide is introduced into the extraction tank, propolis tends to clump, resulting in uneven mixing of carbon dioxide and propolis, which affects the extraction effect. Furthermore, when propolis needs to be discharged from the separation tank, the staff can only collect the propolis in the storage box, place it down, and then retrieve a new storage box to collect it again, which is time-consuming and affects the propolis collection efficiency. Therefore, we propose a supercritical extraction device. Utility Model Content

[0029] A U-shaped frame 8 is fixedly connected to the bottom end of the spiral shaft 6, and a heating wire 9 is installed inside the spiral shaft 6.

[0030] In practical use, through the coordinated arrangement of extraction tank 1, separation tank 2, limiting seat 3, positioning block 4, storage cylinder 5, spiral shaft 6, servo motor 7, U-shaped frame 8, and heating wire 9, during extraction, the operator can introduce liquid carbon dioxide into the extraction tank 1, and then start the servo motor 7. The servo motor 7 drives the spiral shaft 6 to rotate, which can crush the propolis inside the storage cylinder 5. The heating wire 9 can generate heat on the spiral shaft 6, which facilitates the melting of propolis, making the propolis particles smaller and reducing the occurrence of propolis caking. In addition, when the spiral shaft 6 rotates, the U-shaped frame 8 can rotate, which can stir the carbon dioxide solution, making the carbon dioxide solution and propolis mix more evenly and improving the extraction effect.

[0031] In this embodiment, both the extraction tank 1 and the separation tank 2 are fixedly connected to the outer surfaces of the brackets 26, and the bottom end of the brackets 26 is fixedly installed on the upper surface of the base plate 10.

[0032] In practical use, the support 26 makes the extraction tank 1 and the separation tank 2 more stable.

[0033] In this embodiment, a support column 11 is fixedly connected to the upper surface of the base plate 10. The top end of the support column 11 is installed inside the turntable 12 through a bearing. A positioning seat 13 is fixedly connected to the upper surface of the turntable 12. A storage box 14 is placed inside the positioning seat 13.

[0034] In practical use, with the setup of turntable 12, positioning seat 13, storage box 14, discharge pipe 15 and valve 16, when discharging material, the operator can rotate turntable 12 to rotate the storage box 14 at different positions to below the discharge pipe 15 in sequence, which makes it easier to collect the propolis material, making the material collection more efficient, time-saving and labor-saving.

[0035] In this embodiment, a discharge pipe 15 is fixedly connected to the lower surface of the separation tank 2, and a valve 16 is installed inside the discharge pipe 15.

[0036] In practical use, by setting up the discharge pipe 15 and valve 16, opening valve 16 can more quickly discharge the propolis inside the separation tank 2 from the discharge pipe 15.

[0037] In this embodiment, the upper surface of the extraction tank 1 is fixedly connected to the tank cover 17 by bolts, and the inside of the tank cover 17 is equipped with a spiral shaft 6 through a sealed bearing.

[0039] In this embodiment, a feeding pipe 19 is fixedly connected to the upper surface of the barrel cover 17, and a hopper 20 is fixedly connected to the end of the feeding pipe 19 away from the barrel cover 17. A sealing cap 21 is threadedly connected to the inside of the hopper 20. A carbon dioxide feed pipe 22 is fixedly connected to the lower surface of the extraction barrel 1. A carbon dioxide discharge pipe 23 is fixedly connected to the separation barrel 2. A temperature control switch 24 is installed on the outer surface of the extraction barrel 1. The temperature control switch 24 is electrically connected to the heating wire 9 through a wire. An observation window 25 is provided on the outer surface of the separation barrel 2.

[0040] In practical use, the propolis material is poured into the hopper 20 through the feeding pipe 19 and the hopper 20. After being transported by the feeding pipe 19, it falls directly into the storage cylinder 5 inside the extraction tank 1, facilitating the addition of propolis material. The carbon dioxide inlet pipe 22 facilitates the introduction of liquid carbon dioxide into the extraction tank 1, and the carbon dioxide outlet pipe 23 facilitates the discharge of gaseous carbon dioxide from the separation tank 2.

[0041] Working principle: During use, the operator can first add propolis material into the storage cylinder 5 through the hopper 20, and then introduce liquid carbon dioxide into the extraction tank 1 through the carbon dioxide feed pipe 22. Start the servo motor 7 and heating wire 9. The servo motor 7 can crush and melt the propolis at the same time. The U-shaped frame 8 can stir the material. Then the mixture of liquid carbon dioxide and propolis will flow into the separation tank 2 through the conveying pipe 18. The carbon dioxide in the separation tank 2 will be vaporized and discharged through the carbon dioxide discharge pipe 23. The operator can rotate the turntable 12, align the storage box 14 with the discharge pipe 15, and open the valve 16. The extracted propolis can then be discharged from the discharge pipe 15.
