Description

Technical Field

[0001] This utility model relates to the field of extraction technology, specifically to a high-efficiency extraction device for milk thistle extract. Background Technology

[0002] Milk thistle is an annual or biennial herbaceous plant belonging to the genus *Silybum* in the family Asteraceae. It can grow up to 1.2 meters tall, with an erect stem bearing white longitudinal stripes. The leaves are oblong-elliptic with wavy, toothed edges, green with white spots. Its large capitula have a spherical involucre with multiple layers of imbricate bracts. The flowers are purplish-red with a tubular corolla. Native to Europe, North Africa, and western Asia, it is now widely cultivated worldwide. The seeds are used medicinally, and the extract silymarin has various pharmacological effects, including hepatoprotective, antioxidant, and anti-inflammatory properties, making it widely used in pharmaceuticals and health products. Milk thistle extract is primarily obtained from the seeds, and its main active ingredient is silymarin. It is a natural substance with multiple health benefits, showing excellent performance in protecting the liver.

[0003] Currently, in the extraction process of milk thistle extract, an extraction device is required. During the extraction process, impurities, dirt, and some precipitates gradually accumulate inside the drum. The drum needs to be rinsed with clean water or a suitable solvent through the pre-set rinsing pipe of the device. However, when cleaning the drum, the staff usually cannot observe the cleaning status and cannot determine whether the dirt has been completely removed, which affects the cleaning effect of the extraction device and is not conducive to the extraction of milk thistle extract.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a high-efficiency extraction device for milk thistle extract, including a mounting frame 1, an mounting plate 2 fixedly mounted on the upper surface of the mounting frame 1, an extraction chamber 3 fixedly mounted on the upper surface of the mounting plate 2, the lower end of the extraction chamber 3 extending through to the lower surface of the mounting plate 2, and a chamber cover 4 mounted on the upper surface of the extraction chamber 3.

[0024] The auxiliary mechanism is mounted on the mounting frame 1. The auxiliary mechanism includes four limiting rods 5 and a rectangular plate 6. The four limiting rods 5 are fixedly mounted on the upper surface of the mounting plate 2 in a rectangular array. The rectangular plate 6 is slidably mounted on the upper surface of the four limiting rods 5. A centrifugal extraction mechanism 7 is fixedly mounted on the upper surface of the rectangular plate 6. The lower end of the centrifugal extraction mechanism 7 rotates through into the interior of the extraction chamber 3. Two hydraulic cylinders 8 are fixedly mounted on the lower surface of the mounting plate 2. The upper ends of the two hydraulic cylinders 8 both penetrate into the upper surface of the mounting plate 2. The telescopic ends of the two hydraulic cylinders 8 are fixedly connected to the chamber cover 4.

[0025] Furthermore, the auxiliary mechanism also includes four annular limiting plates 9, which are slidably installed on the outer surfaces of the four limiting rods 5, and the upper ends of the four annular limiting plates 9 are fixedly connected to the rectangular plate 6.

[0026] Furthermore, by rotating the two handles 11, the two L-shaped plates 10 are moved away from each other, and the four annular limit plates 9 are released. Then, the two hydraulic cylinders 8 can drive the centrifugal extraction mechanism 7 to move upward, exposing the drum on the centrifugal extraction mechanism 7 from the extraction chamber 3. This makes it easier for the staff to clean the drum more carefully, improving the cleaning effect of the extraction device and thus improving the extraction effect of the extraction device on milk thistle.

[0027] Furthermore, L-shaped plates 10 are slidably mounted on both the left and right ends of the mounting plate 2, and handles 11 are rotatably mounted on the distant surfaces of the two L-shaped plates 10. Mounting grooves 12 are threaded onto both the left and right surfaces of the mounting plate 2, and the near ends of the two handles 11 are threaded into the interior of the two mounting grooves 12 respectively.

[0028] Furthermore, each of the two L-shaped plates 10 has a circular groove 13 inside, and a circular plate 14 is rotatably installed inside each of the two circular grooves 13.

[0029] Furthermore, a fixing plate 15 is fixedly connected to the lower end of the outer surface of each of the four annular limiting plates 9.

[0030] Furthermore, limit plates 16 are fixedly installed on the lower surfaces of both L-shaped plates 10.

[0031] Furthermore, when using this extraction device to extract milk thistle, first prepare the milk thistle raw material and extractant in a suitable ratio. Start the two hydraulic cylinders 8 to open the chamber cover 4, and add the prepared raw material and extractant through the opening of the extraction chamber 3 into the drum of the centrifugal extraction mechanism 7. Start the centrifugal extraction mechanism 7; the lower drum of the centrifugal extraction mechanism 7 rotates at high speed inside the extraction chamber 3. Using centrifugal force, the milk thistle raw material and extractant are thoroughly mixed and the extraction process begins. The active ingredients in the milk thistle are accelerated from the raw material and dissolved into the extractant under centrifugal force. When cleaning the drum is required, the two handles 11 can be rotated to... Two rotary handles 11 drive two L-shaped plates 10 away from each other and away from the four fixed plates 15, thereby releasing the four annular limiting plates 9. At this time, the two hydraulic cylinders 8 can be operated to make the chamber cover 4 move upward. When the chamber cover 4 drives the centrifugal extraction mechanism 7 and the rectangular plate 6 to move upward, the annular limiting plate 9 connected to the rectangular plate 6 moves upward along the four limiting rods 5. The chamber cover 4 drives the centrifugal extraction mechanism 7 and the rectangular plate 6 to move upward, so that the lower end of the centrifugal extraction mechanism 7 is exposed from the inside of the extraction chamber 3. At this time, the staff can clean the drum on the centrifugal extraction mechanism 7 more carefully to remove the attached dirt and residues to ensure the cleaning effect of the drum.
