Description

Technical Field

[0001] This utility model relates to the field of percolation collection technology, specifically a continuous percolation device for the efficient enrichment of total saponins from Panax notoginseng. Background Technology

[0002] Panax notoginseng total saponins, often simply referred to as Panax notoginseng saponins or total saponins, are a general term for natural chemical components extracted from the roots and rhizomes of Panax notoginseng. They are a class of triterpenoid or diterpenoid saponins with sugar molecule linkages, possessing surface activity and various pharmacological activities. The total saponin components are a mixture obtained from the roots and rhizomes of Panax notoginseng after extraction, separation, and purification. Common extraction methods include ethanol / methanol extraction, liquid-liquid extraction, column chromatography, etc., while continuous percolation is also an important extraction method.

[0003] A percolation collection device, patent publication number CN222566871U, involves a process where, during percolation, the filtrate passes through absorbent cotton and falls into a collection tank below. A booster pump is then activated, and the filtrate passes through a filter screen and a circulation pump, rising into an upper booster pipe under the pump's influence. It then falls through a mounting hole in a sealing plug into a lower percolation cylinder, percolating the medicinal material once more. The color depth of the filtrate is observed until its concentration reaches the standard. At this point, the booster pump is turned off, and the filtrate is collected through the collection pipe. This percolation process allows for the recycling of the filtrate, reducing solvent costs and increasing the concentration of the percolated filtrate.

[0004] In the percolation collection process described above and similarly, the solvent slowly percolates through the medicinal powder layer from top to bottom, dissolving and carrying out the active ingredients during the flow. This is a static process. The concentration difference formed by the continuous flow of the static solvent results in the lowest concentration at the bottom of the collection device, which can easily lead to the incomplete dissolution and removal of the active ingredients in the medicinal powder layer at the bottom. In contrast, dynamic collection methods, such as stirring, can easily lead to the dissolution of large molecular impurities such as colloids and starch.

[0005] The prior art document CN222566871U uses a circulating pump to achieve solvent circulation, but the herb bed is always in a static state. There is only a relatively slow seepage between the solvent and the herb, which makes it difficult to form an effective concentration gradient at the bottom of the bed, resulting in limited extraction efficiency.

[0008] The first aspect is the design of a continuous percolation device for the efficient enrichment of total saponins from Panax notoginseng, which includes a main component, the main component including a collection cylinder, and a spraying component and a lifting component are provided inside the collection cylinder;

[0014] Furthermore, the diffuser mechanism includes a diffuser plate, a top cover on the collecting cylinder, a plurality of solvent adding tubes on the top cover, a connecting tube on the solvent adding tube, and the diffuser plate on the connecting tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

When the two move relative to each other, they can form a counterflow between the material bed and the solvent, which significantly improves the concentration gradient difference at the contact interface, thereby enhancing the mass transfer efficiency and extraction effect.

[0023] 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.

[0024] A continuous percolation device for the efficient enrichment of total saponins from Panax notoginseng, such as Figures 1-4 As shown, the system includes a main component 1, which includes a collection cylinder 101. The collection cylinder 101 contains a spraying component 2 and a lifting component 3. The lifting component 3 is located at the bottom of the collection cylinder 101 and includes a lifting plate 307 driven by a drive component for supporting the material. The spraying component 2 is located at the top of the collection cylinder 101 and includes a dispersing mechanism for spraying solvent towards the lifting plate 307. The Panax notoginseng powder is placed on the lifting plate 307, which is driven to reciprocate within the collection cylinder 101. When the lifting plate 307 rises, the target Panax notoginseng powder and the solvent sprayed by the spraying component 2 flow in opposite directions, increasing the concentration gradient difference. When the lifting plate 307 descends, the spraying component 2 stops spraying solvent.

[0025] like Figure 4 As shown, the driving component includes a drive motor 302, and a base plate 301 is provided on the collection cylinder 101, with the drive motor 302 located at the bottom of the base plate 301.

[0026] It should be noted that the second sensor 304 obtains the relative position of the lifting plate 307 and the solvent surface, and controls the drive motor 302 to drive the lifting plate 307 so that the height of the lifting plate 307 is above the solvent. As the solvent is discharged through the outlet pipe 106, the lifting plate 307 slowly descends to prevent the solvent in the collection cylinder 101 from being impacted by the lifting plate 307.

[0027] like Figure 4 As shown, a first sensor 303 and a second sensor 304 are provided on the base plate 301.

[0028] like Figures 2-4 As shown, a reciprocating lead screw 305 is provided at one end of the output shaft of the drive motor 302. The lifting plate 307 is threadedly connected to the reciprocating lead screw 305. Multiple limit rods 306 are provided on the base plate 301. The lifting plate 307 is slidably connected to the limit rods 306. Both the base plate 301 and the lifting plate 307 are provided with permeable mesh. A control terminal 105 is provided on the collection cylinder 101. The control terminal 105 is electrically connected to the drive motor 302.

[0029] In a preferred embodiment of this device, the position of the lifting plate 307 can be monitored by setting a first sensor 303 on the base plate 301. Those skilled in the art will understand that timer control or manual control can also be used to make the rising phase of the lifting plate 307 approximately synchronized with the solvent spraying phase, so as to form countercurrent flow.

[0030] It should be noted that when the drive motor 302 starts, it drives the reciprocating screw 305 to rotate. Since the lifting plate 307 is threaded onto the reciprocating screw 305 and is limited by the limiting rod 306, the lifting plate 307 will move up and down along the reciprocating screw 305. Meanwhile, the substances extracted from the Panax notoginseng powder by the solvent pass through the permeation mesh and are deposited at the bottom of the collection cylinder 101.

[0031] like Figure 2 and Figure 3 As shown, the diffuser mechanism includes a diffuser plate 204, a top cover 201 on the collection cylinder 101, a plurality of solvent addition tubes 203 on the top cover 201, a connecting tube 205 on the solvent addition tubes 203, and the diffuser plate 204 on the connecting tubes 205.

[0032] It should be noted that since there are multiple solvent addition tubes 203, different solvents can be selected and added through the solvent addition tubes 203 according to the specific type and state of the Panax notoginseng powder, and the solvents will flow out evenly through the diffuser plate 204 to contact the Panax notoginseng powder.

[0033] like Figure 2As shown, a second docking ring 202 is provided on the top cover 201, and a first docking ring 104 is provided on the collection cylinder 101. The second docking ring 202 and the first docking ring 104 are connected by threads. A liquid outlet pipe 106 is provided at the bottom of the collection cylinder 101, a feed inlet 102 is opened on the collection cylinder 101, and a bracket 103 is provided on the collection cylinder 101.

[0034] It should be noted that when the Panax notoginseng powder is placed on the lifting plate 307 and the drive motor 302 starts, it drives the reciprocating screw 305 to rotate. Since the lifting plate 307 is threaded onto the reciprocating screw 305 and is limited by the limiting rod 306, the lifting plate 307 will rise and fall along the reciprocating screw 305. Meanwhile, the substances extracted from the Panax notoginseng powder by the solvent pass through the permeation mesh and are deposited at the bottom of the collection cylinder 101. When the first sensor 303 detects that the lifting plate 307 has risen, the spraying assembly 2 sprays the solvent. At this time, the solvent flows downward, while the lifting plate 307 moves upward. To enhance the convective flow of solvent and increase the concentration gradient difference, thereby improving the percolation effect, when the first sensor 303 detects that the lifting plate 307 is descending, the spraying assembly 2 pauses the solvent spraying to accumulate solvent for spraying again when the lifting plate 307 rises. The second sensor 304 obtains the relative position of the lifting plate 307 and the solvent surface and controls the drive motor 302 to drive the lifting plate 307 so that the height of the lifting plate 307 is above the solvent. As the solvent is discharged through the outlet pipe 106, the lifting plate 307 descends slowly to prevent the solvent in the collection cylinder 101 from being impacted by the lifting plate 307.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
