Description

Technical Field

[0001] The utility model relates to the technical field of Chinese herbal medicine extraction equipment, in particular to an extraction device for gastrodia elata raw materials used for preparing instant powder. Background Technique

[0002] Gastrodin is an important component in gastrodia elata and has high medicinal value. Therefore, gastrodin is widely used in some Chinese medicine instant powder products. At present, the gastrodin extraction process is as follows: take the dried raw materials, crush and grind the gastrodia elata, then screen it, mix the ground gastrodia elata powder with the extraction solvent into a Chinese medicine extraction tank for heating extraction, then filter the gastrodia elata extract, combine the filtrate, use a rotary evaporator to recover ethanol under reduced pressure to make the filtrate into a paste, and calculate the paste yield; and use ultraviolet spectrophotometry and HPLC method to determine the content of gastrodin.

[0003] After retrieval, the patent No. CN216963625U discloses a Chinese medicine extraction tank. In the utility model, a vortex plate similar to an arc-shaped wedge block is arranged inside the tank body, so that when the turntable rotates, the drugs and solvents at the bottom vortex and rise along the inclined surface of the vortex plate, which not only avoids the accumulation of drugs, but also avoids the damage to the drug body by the traditional stirring device, making all drugs fully extracted; the utility model also sets a filter net at the discharge port to filter the dregs with the filter net to separate the dregs from the medicinal liquid, reducing the burden on the staff.

[0004] In the above solution, the setting of the vortex plate and the filter net is adopted to increase the extraction effect. However, the extraction tank is not provided with a crushing mechanism for Chinese herbal medicine raw materials, and it is necessary to rely on technicians to pour the crushed drugs into the inside of the tank body. To ensure the extraction effect of Chinese medicine, the Chinese medicine will be crushed multiple times, resulting in more cumbersome Chinese medicine extraction operations and being not conducive to the full extraction of gastrodin.

[0005] Therefore, an extraction device for gastrodia elata raw materials used for preparing instant powder is proposed, which has the advantages of being easy for pretreatment of Chinese herbal medicine and full extraction of effective components, and thus solves the problems in the above background technique.

For the stirring motor 2, the grinding motor 14 and the crushing motor 15, the control mode of the present utility model is to control by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present utility model mainly protects mechanical devices, so the control mode and wiring layout are not explained in detail in the present utility model. The extraction tank 1 of the present device is mainly for extracting the effective components in Gastrodia elata, and can also be used for extracting other Chinese medicine components in Chinese herbal medicine instant powder products;

[0024] In one embodiment, a slag discharge nozzle 8 communicating with the filter cylinder 4 is provided at the bottom of the extraction tank 1, and a gate valve 10 is installed on the surface of the slag discharge nozzle 8. A liquid discharge nozzle 9 is communicated with the edge of the bottom of the extraction tank 1, and an exhaust valve 12 is communicated with the right side of the top surface of the extraction tank 1. Through the settings of the slag discharge nozzle 8 and the liquid discharge nozzle 9, it is easy to discharge Gastrodia elata residues and Gastrodia elata extraction liquid. Through the setting of the exhaust valve 12, it is easy to exhaust the extraction tank 1.

[0025] In one embodiment, a sealing cover 25 is installed at the open top of the feeding shell 7 through bolts. The cross-section of the feeding shell 7 is of a U-shaped structure, and two guiding plates 23 are arranged in a horn-shaped structure at the upper part inside the feeding shell 7.

[0029] Working principle:

[0030] During use, first put the gastrodia raw materials into the feeding shell 7, and then pre-inject the gastrodin extraction solvent into the extraction tank 1. By starting the crushing motor 15 to drive the left crushing roller 17 to rotate, the left gear 18 on the roller shaft of the left crushing roller 17 drives the right crushing roller 19 to rotate under the action of meshing with the right gear 20, so that the left crushing roller 17 and the right crushing roller 19 perform crushing treatment on the added gastrodia raw materials. Then start the grinding motor 14 to drive the grinding roller 16 to rotate. Since the grinding surface of the grinding roller 16 corresponds to the grinding arc surface 21 at the inner bottom of the feeding shell 7, the grinding roller 16 grinds the crushed materials entering the inner bottom of the feeding shell 7 until the gastrodia powder that meets the aperture of the filter screen 22 enters the filter cylinder 4 through the gastrodia powder outlet nozzle 24. During this process, start the stirring motor 2 to drive the shaft rod 3 and several groups of stirring rods 5 arranged on its surface to rotate, so that several groups of stirring rods 5 continuously stir the gastrodia powder in the filter cylinder 4, and start the electric heating tube 6 to heat, so that the gastrodin component in the gastrodia can be fully dissolved in the extraction solvent. After the extraction is completed, open the gate valve 10 of the slag discharge nozzle 8 to discharge the gastrodia residues, and then discharge the gastrodia extraction solution through the liquid discharge nozzle 9 for subsequent purification and solvent separation work.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
