[0002] In the fields of modern industry and biotechnology, the extraction of plant essence liquid is an important technology, which is widely used in the preparation of medicines, food additives and other bioactive substances. The existing plant essence liquid extraction technology mainly adopts the method of static soaking or single-pass. In this method, the plant raw materials are usually put into a tank containing a solvent and soaked for a period of time, and the effective components are extracted by relying on the contact between the solvent and the plant materials; however, in most of the extraction devices used in this method, the contact between the solvent and the plant raw materials is not sufficient, resulting in low extraction efficiency. Summary of the Invention

[0036] As Figures 1-12 shown, a plant extract essence preparation device is described in detail:

[0037] A plant extract essence preparation device includes a cylindrical box 101 with a cover plate 201 fixed at the upper end. An addition port 102 is provided at the upper end of the side of the cylindrical box 101. A central gear 202 is rotatably penetrated through the center of the cover plate 201. A plurality of arc knives 203 are fixed at the lower end of the central gear 202. The plurality of arc knives 203 are all in sliding contact with the inner wall of the cylindrical box 101. A square rod 301 is connected to the center of the central gear 202. Two press rollers 302 are symmetrically rotatably arranged at the lower end of the square rod 301.

[0038] During extraction, an extraction solvent is added into the cylindrical box 101, and the extraction solvent is heated by a heating device installed at the lower end of the cylindrical box 101. Then, plant raw materials are added into the cylindrical box 101 through the addition port 102. During this process, a first motor installed on the cover plate 201 drives the central gear 202, thereby driving the plurality of arc knives 203 to rotate. When each arc knife 203 passes through the addition port 102, it cuts the plant raw materials, so that the plant raw materials are cut into small sections, enabling the plant raw materials to better contact the extraction solvent for extraction. At the same time, when the central gear 202 rotates, it can drive the two press rollers 302 to rotate through the square rod 301, thereby rotatably rolling the plant raw materials in the cylindrical box 101, further enabling the extraction solvent to fully contact the plant raw materials and enabling the extraction solvent to fully infiltrate the plants, improving the extraction efficiency.

[0039] Among them, as Figure 7As shown, one of the arc-shaped knives 203 can be set in the shape of an arc plate for cutting plant materials, while the remaining multiple arc-shaped knives 203 are set in the shape of comb teeth. During cutting, the rotating arc-shaped knives 203 in the shape of comb teeth perform layered cutting on the part of the plant inserted into the cylindrical box 101, turning the plant into layers. At this time, the layered plant does not break away from the plant body. Thus, when the arc-shaped knife 203 in the shape of an arc plate passes by, the plant is cut off and dropped, greatly increasing the contact area between the plant raw material and the solvent, further enabling the solvent to fully contact the plant raw material, allowing the solvent to fully infiltrate the plant, and improving the extraction efficiency. Further, scraping edges can be provided on both sides of the comb-shaped blades, which can separate the plant layers after cutting, ensuring that the solvent enters between the two layers. Moreover, the scraping edges can also cut and stab the surface of the layered plant, further enabling the solvent to fully infiltrate the plant and improving the extraction efficiency.

[0040] Among them, the comb-shaped blades of each arc-shaped knife 203 in the shape of comb teeth are arranged in a mutually staggered manner; or the arc-shaped knives 203 in the shape of comb teeth and the arc-shaped knives 203 in the shape of arc plates can be arranged at intervals in turn, that is, the plant is cut in the form of passing through the arc-shaped knife 203 in the shape of an arc plate for cutting - the arc-shaped knife 203 in the shape of comb teeth for layering - the arc-shaped knife 203 in the shape of an arc plate for cutting in sequence.

[0041] Meanwhile:

[0042] The pressing roller 302 is cylindrical, which can have a smooth circular surface or a plurality of knife strips evenly distributed on the surface. When the plant raw material is relatively soft, the pressing roller 302 with a smooth circular surface can be used for only rolling; when the plant raw material is relatively hard, the pressing roller 302 with knife strips on the surface can be used. On the premise of not affecting the surface rolling of the pressing roller 302, each knife strip rolling to the lower part will cut the plant raw material again, further increasing the contact area between the plant raw material and the extraction solvent. At the same time, the volume of the plant raw material is reduced, and it can be better rolled and deformed by the pressing roller 302, ensuring the rolling effect.

[0043] Furthermore:

[0044] A partition net plate 401 is provided inside the cylindrical box 101, and two pressing rollers 302 roll on the upper end of the partition net plate 401. A discharge pipe 104 is provided at the lower end of the cylindrical box 101.

[0045] Through the setting of the partition net plate 401, the cylindrical box 101 is divided into upper and lower two spaces. The plant raw material is isolated by the partition net plate 401 in the upper space and cooperates with the two pressing rollers 302 to complete the rolling of the plant raw material. The plant raw material is isolated by the partition net plate 401 and will not enter the lower part of the cylindrical box 101. Then, after the extraction is completed, the extraction liquid can be discharged through the discharge pipe 104, and at the same time, the separation of the extraction liquid and the plant raw material is formed.

[0046] Further:

[0047] A support frame 402 penetrates through the center of the cylindrical box 101. The upper end of the support frame 402 is fixedly connected to the partition net plate 401. A spring I 303 is provided between the square rod 301 and the center wheel 202.

[0048] By installing an electric telescopic rod between the support frame 402 and the cylindrical box 101 to control the lifting of the support frame 402, the partition net plate 401 is driven to lift. Thus, when the partition net plate 401 rises, it can push the two pressure rollers 302 to rise, and then compress the spring I 303, so as to adjust the pressure of the pressure rollers 302 on the plant raw materials, in order to adapt to the rolling of plant raw materials with different hardnesses.

[0049] At the same time, after rolling for a period of time, by starting the electric telescopic rod to reciprocate and stretch, the partition net plate 401 can reciprocate up and down in the cylindrical box 101. During the reciprocating up and down process, the extraction liquid forms a reciprocating flushing of the mesh holes of the partition net plate 401, so as to prevent the plant from being rolled into the mesh holes of the partition net plate 401 during the rolling process of the pressure rollers 302, affecting the flow of the extraction liquid at the upper and lower ends of the partition net plate 401.

[0050] As Figures 1-12 shown:

[0051] A retaining ring is fixed to the upper end of the square rod 301. A discharge port 103 is provided at the lower end of the side surface of the cylindrical box 101. An arc-shaped blocking plate 601 penetrates through the connection part of the discharge port 103 and the cylindrical box 101. An adjusting screw rod 602 is rotatably arranged at the upper end of the discharge port 103, and the adjusting screw rod 602 is threadedly connected to the arc-shaped blocking plate 601.

[0052] Through the setting of the retaining ring, when the square rod 301 moves downward in the center wheel 202 under the elastic force of the spring I 303, the retaining ring will press against the upper end of the center wheel 202, so as to limit the downward sliding state of the square rod 301 under the elastic force of the spring I 303. Thus, after the support frame 402 drives the partition net plate 401 to descend to a certain height by controlling the elongation of the electric telescopic rod, the partition net plate 401 will be separated from the two pressure rollers 302. At this time, the partition net plate 401 is at the discharge port 103. When the partition net plate 401 descends to the lower end of the discharge port 103, at this time, the arc-shaped blocking plate 601 can be controlled to rise by rotating the adjusting screw rod 602, so that the discharge port 103 is opened, and then the plant raw materials on the partition net plate 401 can be taken out through the discharge port 103.

[0053] Further:

[0054] A rotating shaft 701 is rotatably arranged at the upper end in the discharge port 103. A baffle plate 702 vertically penetrates through the lower end of the rotating shaft 701, and a brush strip 703 is fixed to the lower end of the baffle plate 702.

[0055] In order to improve the efficiency of removing the plant raw materials on the partition net plate 401, the dial plate 702 can be pushed to extend into the cylindrical box 101 on the rotating shaft 701, so that the brush strip 703 contacts the upper end surface of the partition net plate 401, and through the rotation of the rotating shaft 701, the swing of the brush strip 703 driven by the dial plate 702 is formed, achieving the purpose of swinging and cleaning the plant raw materials on the partition net plate 401, and improving the efficiency of removing the plant raw materials on the partition net plate 401;

[0056] Meanwhile, a second motor (not shown in the figure) can be installed at the lower end of the support frame 402 to drive the partition net plate 401. Through the cooperation of the rotating partition net plate 401 and the brush strip 703, the plant raw materials can be taken out more quickly.

[0057] As Figures 1-12 shown:

[0058] A transverse shaft 501 penetrates horizontally through the addition port 102, and a plurality of convex rib plates 504 are uniformly fixed on the outer surface of the transverse shaft 501.

[0059] A U-shaped plate 502 rotates on the transverse shaft 501, and a spring II 503 is provided between the U-shaped plate 502 and the addition port 102.

[0060] The transverse shaft 501 is driven by a third motor installed on the side surface of the U-shaped plate 502 to rotate in the addition port 102, whereby the plant raw materials can be pushed inward. Moreover, through the elastic force of the spring II 503, the extrusion of the plant raw materials in the addition port 102 by the transverse shaft 501 can be better formed, ensuring the efficiency of the rotating transverse shaft 501 in pushing the plant raw materials inward;

[0061] Through the arrangement of the plurality of convex rib plates 504, the efficiency of the transverse shaft 501 in pushing the plant raw materials inward can be further improved;

[0062] Furthermore:

[0063] By providing a spiral groove 505 on the transverse shaft 501, through the arrangement of the spiral groove 505, the axial limit of the plant raw materials can be formed, and then the cutting of the plants by the arc-shaped knife 203 can be better coordinated.

[0064] As Figures 1-12 shown:

[0065] The preparation method using the described plant extract essence liquid preparation device includes

[0066] S1. After cleaning the required plants and drying them, weigh an appropriate amount of plant raw materials and send them to the addition port 102. The plant raw materials are sent into the cylindrical box 101 through the addition port 102. Meanwhile, the solvent in the cylindrical box 101 is heated;

[0067] S2. During the process of feeding the plant raw materials into the feeding port 102, the driving center wheel 202 drives a plurality of arc knives 203 to rotate. The rotating arc knives 203 will cut the plants into small segments and fall into the cylindrical box 101 for cooking and extraction with the heated solvent. At the same time, the rotating center wheel 202 will drive the pressure roller 302 to rotate through the square rod 301 to form rolling pressure on the small plant segments;

[0068] S3. After the extraction is completed, the extract is taken out for concentration to obtain the essence.

[0069] A plant extract essence prepared by using the said preparation method.
