Description

Technical Field

[0002] Dendrobium, as a medicinal plant, contains polysaccharides that possess antioxidant, antitumor, immune-regulating, and blood sugar-lowering functions, giving it high medicinal value. To utilize its various health benefits and medicinal value, it is necessary to extract the polysaccharides contained in Dendrobium.

[0003] Current methods for extracting Dendrobium officinale generally involve hot water extraction, which is low-cost but time-consuming. To improve extraction efficiency, hot water extraction is often combined with ultrasonic extraction. Utilizing the physical effects of ultrasound, polysaccharide release is effectively promoted, resulting in high extraction efficiency and short extraction time, while avoiding chemical contamination and achieving better extraction effects. During the extraction of Dendrobium officinale polysaccharides, it is necessary to strictly control not only the temperature of the hot water but also the uniformity of the ultrasound waves to ensure that the Dendrobium officinale fragments are evenly exposed to ultrasonic radiation, thereby improving the extraction rate and quality of polysaccharides.

[0004] Existing extraction devices typically only include a heating wire, a temperature sensor, and an ultrasonic generator in the extraction tank. The ultrasonic generator is usually fixed at the bottom or side of the extraction tank, which can easily lead to uneven ultrasonic waves. Furthermore, as the ultrasonic time increases, the heat generated by the ultrasonic waves can cause the temperature to rise, making it difficult to control the extraction temperature. Based on this, an extraction device for Dendrobium polysaccharides is proposed. Utility Model Content

[0005] This invention provides an extraction device for Dendrobium polysaccharides, which solves the problem mentioned in the above technical background that the ultrasonic generator of the extraction device is generally fixed at the bottom or one side of the extraction tank, which easily leads to uneven ultrasonic waves. Furthermore, as the ultrasonic time increases, the thermal effect generated by the ultrasonic waves easily causes the temperature to rise, which is not conducive to controlling the constant extraction temperature.

[0006] An extraction device for Dendrobium polysaccharides includes an extraction tank. A rotating groove is formed at the top of the extraction tank, and a turntable is rotatably connected within the rotating groove.

A temperature sensor is fixedly provided at the bottom of the extraction tank. A cooling chamber is formed on the inner wall of the extraction tank, and a circulation mechanism for coolant within the cooling chamber is fixedly provided on one side of the outer wall of the extraction tank.

[0012] Preferably, the bottom of the extraction tank is fixedly provided with a discharge pipe, the bottom of the discharge pipe is threadedly connected with a filter disc, and a control valve is provided on the discharge pipe.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model drives the rotating shaft and gear to rotate by a drive motor.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-4 As shown, an extraction device for Dendrobium polysaccharides includes an extraction tank 1. A rotating groove 2 is formed at the top of the extraction tank 1, and a turntable 3 is rotatably connected within the rotating groove 2. A feed inlet is formed on one side of the turntable 3. An annular groove 4 is formed on the inner wall of the rotating groove 2, and an annular slider 5 is slidably connected within the annular groove 4. The annular slider 5 is fixedly connected to the outer wall of the turntable 3. A drive mechanism for rotating the turntable 3 is provided on one side of the top of the extraction tank 1. An ultrasonic generator 6 is fixedly provided on one side of the top of the turntable 3. An ultrasonic probe 7 is provided at the bottom of the ultrasonic generator 6 and extends through into the extraction tank 1. A temperature sensor 8 is fixedly provided at the bottom of the extraction tank 1. A cooling chamber 9 is formed on the inner wall of the extraction tank 1, and a circulation mechanism for the coolant in the cooling chamber 9 is fixedly provided on one side of the outer wall of the extraction tank 1.

[0023] The driving mechanism includes a driving groove 10 opened on one side of the annular slide 4. A driving motor 11 is fixedly installed on one side of the top of the extraction tank 1. A rotating shaft 12 is fixedly connected to the output end of the driving motor 11. The rotating shaft 12 extends through into the driving groove 10 and is fixedly connected to a gear 13. The gear 13 meshes with a gear ring 14, which is fixedly connected to the outer wall of the annular slider 5.

[0024] The drive motor 11 drives the rotating shaft 12 and gear 13 to rotate. The gear 13 meshes with the gear ring 14 to rotate, which in turn drives the turntable 3 to rotate. This causes the ultrasonic generator 6 and ultrasonic probe 7 on the turntable 3 to rotate. The ultrasonic probe 7 rotates inside the extraction tank 1, so that the emitted ultrasonic waves can be evenly radiated to the Dendrobium fragments inside the extraction tank 1, thereby improving the efficiency of ultrasonic extraction.

[0025] A liquid pump 15 is fixedly installed on the side wall of the extraction tank 1. The inlet pipe 16 of the liquid pump 15 extends through to the bottom of the cooling chamber 9. The outlet pipe 17 of the liquid pump 15 is fixedly connected to a cooling tank 18. The cooling tank 18 is fixedly connected to a circulation pipe 19, which extends through to the top of the cooling chamber 9. The liquid is pumped into the cooling tank 18 through the inlet pipe 16, the liquid pump 15, and the outlet pipe 17. The coolant cooled in the cooling tank 18 is then transported back into the cooling chamber 9 through the circulation pipe 19. This circulation of the coolant in the cooling chamber 9 improves cooling efficiency and reduces the cooling effect of the liquid in the extraction tank 1. The temperature of the sound rise can be quickly reduced to the set value. The cooling box 18 is equipped with a semiconductor refrigeration chip. The cooling surface of the semiconductor refrigeration chip is located inside the cooling box 18, and the heating surface of the semiconductor refrigeration chip is located outside the cooling box 18. A heat sink is provided on the heating surface of the semiconductor refrigeration chip. After the semiconductor refrigeration chip is powered on, the cooling surface of the semiconductor refrigeration chip cools the circulating cooling water in the cooling box 18, and the heat from the cooling surface of the semiconductor refrigeration chip is transferred to its heating surface, and then dissipated through the heat sink on the heating surface, effectively cooling the circulating coolant in the cooling box 18.

[0026] A partition 20 is fixedly installed inside the cooling chamber 9. The partition 20 divides the cooling chamber 9 into a spiral shape, so that the coolant in the cooling chamber 9 flows in a spiral shape along the partition, increasing the flow area and improving the cooling efficiency.

[0027] A stirring motor 21 is fixedly installed at the top center of the turntable 3. The stirring motor 21 is fixedly connected to a rotating rod 22. The rotating rod 22 extends through into the extraction tank 1 and is fixedly connected to a stirring blade 23. The stirring motor 21 drives the stirring rod 22 and the stirring blade 23 to rotate and stir the mixture in the extraction tank 1, so that the Dendrobium fragments and the extract are in uniform contact.

[0028] The stirring blade 23 is equipped with a heating wire 24, which heats the liquid in the extraction tank 1 while stirring, making the liquid more evenly heated.

[0029] The temperature sensor 8 is electrically connected to the infusion pump 15 and the heating wire 24. When the temperature changes from the set value, the infusion pump 15 and the heating wire 24 are activated to keep the extraction temperature constant.

[0030] The bottom of the extraction tank 1 is fixedly provided with a discharge pipe 25, and the bottom of the discharge pipe 25 is threadedly connected to a filter disc 26. A control valve is provided on the discharge pipe 25 to facilitate the filtration of the extracted polysaccharide extract.

[0031] In use, equal proportions of Dendrobium fragments and hot water are added to extraction tank 1. When only hot water extraction of Dendrobium polysaccharides is required, the temperature inside extraction tank 1 is kept constant by temperature sensor 8 and heating wire 24. When hot water and ultrasound are needed to extract Dendrobium polysaccharides, the drive motor 11 is started to drive the rotating shaft 12 and gear 13 to rotate. Gear 13 meshes with gear ring 14 to rotate, which in turn drives the turntable 3 and the ultrasonic generator 6 and ultrasonic probe 7 on the turntable 3 to rotate, so that the emitted ultrasonic waves can be evenly radiated to the Dendrobium fragments inside extraction tank 1. As the ultrasound time increases, the ultrasonic waves... When the heat effect generated by the sound waves raises the temperature of the extract, the temperature sensor 8 detects this and the infusion pump 15 starts, pumping the coolant in the cooling chamber 9 into the cooling tank 18. The coolant, after being cooled by the cooling tank 18, is then transported back to the cooling chamber 9 through the circulation pipe 19. This cycle improves the cooling efficiency, allowing the temperature in the extraction tank 1, which is raised by ultrasound, to quickly drop to the set value and maintain a constant extraction temperature. Through the cooperation of the cooling chamber 9, the temperature sensor 8, and the heating wire 24, the temperature in the extraction tank 1 is kept at a constant value, avoiding the effect and efficiency of Dendrobium polysaccharide extraction due to excessively high or low temperatures.

[0032] It should be noted that, for the present invention as fully described, there may be various variations and modifications, and it is not limited to the specific embodiments described above. In summary, the scope of protection of this utility model should include those variations, substitutions, and modifications that are obvious to those skilled in the art, and the appended claims shall prevail.
