Description

Technical Field

[0001] The invention relates to a dry distillation extraction method of hawthorn kernel extract for treating HPV virus, in particular to a dry distillation extraction method of hawthorn kernel extract for treating HPV virus applied to the field of hawthorn kernel processing. Background Art

[0002] Using hawthorn kernel as raw material, adopting the segmented activation extraction technology under specific high temperature and high pressure can extract "Rosy Liquid". The function of "Rosy Liquid" is that it can kill a variety of pathogenic bacteria and fungi at the same time.

[0003] For example, the patent with the publication number CN1100133C, a method for extracting hawthorn kernel distillate oil and its production, discloses the extraction method of hawthorn kernel extract, but the effective components in the extract obtained by distillation are relatively few. Therefore, there is also a dry distillation extraction method in the prior art, such as a method and device for dry distilling hawthorn kernel extract with the publication number CN110923056A.

[0004] However, in the existing dry distillation extraction methods, since the materials need to be pyrolyzed at high temperature in the dry distillation equipment during the dry distillation stage, the materials are bound to accumulate in the dry distillation equipment, which will lead to uneven heating and thus affect the decomposition process. Although the existing dry distillation equipment has a stirring function, the stirring device will cause the carbonized hawthorn kernels to break and generate a large amount of dust during the stirring process, reducing the quality of the extract. Moreover, the horizontal dry distillation equipment is large in volume. In addition, the existing dry distillation process cannot well achieve continuous production, and each time of reheating will consume a large amount of energy. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is how to make the hawthorn kernels evenly heated during the dry distillation process, avoid the generation of a large amount of dust, and how to achieve continuous dry distillation to save energy consumption.

[0006] To solve the above problems, the present invention provides a dry distillation extraction method of hawthorn kernel extract for treating HPV virus, including the following extraction steps: S1. Pretreatment: First, soak the dry hawthorn kernels in water for 10 - 12 hours to make them fully absorb water and expand. After the soaking ends, drain the water and put them into the dry distillation furnace for dry distillation; S2. Dry distillation: Start the liquefied gas burner to heat the dry distillation furnace. The heating temperature gradually rises from room temperature to 200 °C, and then the hawthorn kernels start to decompose. The heating temperature range is controlled at 200 - 350 °C. The flue gas generated during the heating process is introduced into the condensation coil, and the flue gas condenses into a liquid. This part of the liquid is the preliminary extract obtained; S3. Purification: Let the preliminarily extracted liquid stand for precipitation. After filtering off the precipitate, pour the liquid into a distillation flask and heat it. The active ingredients will volatilize when heated and then be condensed to obtain the target extract. Among them, the retort furnace includes a vertical furnace body, a furnace liner fixedly connected to the upper end inside the vertical furnace body, liquefied gas burner inlet pipes and combustible gas return pipes fixedly connected to the left and right sides of the vertical furnace body, a slag discharge port fixedly connected to the bottom of the furnace liner and penetrating to the outside of the vertical furnace body, a flue gas collection pipe fixedly connected to the upper end of the vertical furnace body and communicating with the inside of the furnace liner, a feeding port opened at the upper end of the vertical furnace body and communicating with the inside of the furnace liner, a combustion waste gas discharge pipe fixedly connected to the upper end of the vertical furnace body, and a pressure gauge and a thermometer installed at the upper end of the vertical furnace body and extending into the inside of the furnace liner.

[0007] In the above dry distillation extraction method of the hawthorn seed extract for treating HPV virus, the hawthorn seed extract is extracted by the dry distillation method, which effectively increases the content of active ingredients in the extract. And during the dry distillation process, the bottom-up turning of the hawthorn seeds makes them evenly heated and reduces the generation of dust, which can further effectively improve the purity of the extract and also enable the continuous progress of the dry distillation process, saving energy consumption.

[0008] As a further improvement of the present application, a servo motor is also installed in the middle of the upper end of the vertical furnace body, and a high-temperature resistant telescopic column connected to the output end of the servo motor is placed inside the furnace liner. The lower end of the high-temperature resistant telescopic column is fixedly connected with a plurality of surrounding material scooping units, and a plurality of driving motors respectively connected to each material scooping unit are installed inside the lower end of the high-temperature resistant telescopic column.

[0009] As a further improvement of the present application, the material scooping unit includes a turning seat, a driving shaft fixedly connected to the turning seat and connected to the output end of the driving motor, a telescopic groove opened on the side wall of the turning seat away from the driving shaft, and a porous material plate fixedly connected to the inside of the telescopic groove.

[0010] As a supplement to the further improvement of the present application, a gap of 2 - 3 cm is left between the turning seat and the lower end of the high-temperature resistant telescopic column, and a support sleeve sleeved on the outside of the driving shaft is fixedly connected to the side wall of the lower end of the high-temperature resistant telescopic column. A gap of 2 - 5 mm is left between adjacent two turning seats.

[0011] As a further improvement of the present application, preheating expansion units are fixedly connected to both side walls of the porous material plate, and the area of the preheating expansion unit after expansion is smaller than the area of the porous material plate.

[0012] As another improvement of the present application, the preheating and expansion unit includes side sealing plates, and high-temperature resistant corrugated telescopic sleeves fixedly connected between the side sealing plates and the porous material plates. The side walls of the side sealing plates, the high-temperature resistant corrugated telescopic sleeves, and the porous material plates enclose a sealed space. A plurality of electrostrictive rods are fixedly connected between the side walls of the side sealing plates and the porous material plates at equal intervals, and the remaining part of the sealed space except for the electrostrictive rods is filled with a force-enhancing filler.

[0013] As a supplement to another improvement of the present application, the electrostrictive rod includes a plurality of alternately connected metal segments and electrostrictive segments, and the length of the metal segment is greater than the length of the electrostrictive segment.

[0014] As a supplement to another improvement of the present application, the force-enhancing filler is of a honeycomb mesh structure, and the force-enhancing filler is made of a high-temperature resistant elastic metal material.

[0015] In summary, using the method of dry distillation to extract the hawthorn seed extract effectively improves the yield of the extract. The high-temperature resistant telescopic column drives the material holding unit to move up and down, and cooperates with the rotational movement of the material holding unit to perform a bottom-up flipping of the hawthorn seeds in the dry distillation stage, enabling the hawthorn seeds to be evenly heated, thereby effectively increasing the yield, avoiding excessive heating of the hawthorn seeds near the heat source at the bottom and generating ineffective components, and the bottom-up flipping is relatively gentle on the hawthorn seeds, not causing the hawthorn seeds to break and generate a large amount of dust, effectively reducing the burden of the purification work of the extract. Additionally, using the scalability of the material holding unit can preheat the hawthorn seeds, saving energy consumption and effectively improving production efficiency at the same time.

Specific implementation mode

[0018] The following will describe the two implementation modes of this application in detail with reference to the accompanying drawings.

[0019] The first implementation mode: As Figure 1 shown, it includes the following extraction steps: S1. Pretreatment: First, soak the dried hawthorn kernels in water for 10 - 12 hours to make them fully absorb water and expand. After soaking, drain the water and put them into the retort furnace for carbonization; S2. Carbonization: Start the liquefied gas burner to heat the retort furnace. The heating temperature gradually rises from room temperature to 200 °C, and then the hawthorn kernels start to decompose. The heating temperature range is controlled at 200 - 350 °C. The flue gas generated during the heating process is introduced into the condensation coil, and the flue gas condenses into a liquid. This part of the liquid is the preliminary extract obtained; S3. Purification: Let the preliminary extract stand and precipitate, filter off the precipitate, pour the liquid into a distillation flask and heat it. The active ingredients volatilize due to heat, and then the target extract is obtained through condensation; As Figure 2As shown in the figure, the retort furnace includes a vertical furnace body 1, a furnace liner 2 fixedly connected to the upper end inside the vertical furnace body 1, a liquefied gas burner inlet pipe 3 and a combustible gas return pipe 4 fixedly connected to the left and right sides of the vertical furnace body 1, a discharge slag port 5 fixedly connected to the bottom of the furnace liner 2 and penetrating to the outside of the vertical furnace body 1, a flue gas collection pipe 6 fixedly connected to the upper end of the vertical furnace body 1 and communicating with the inside of the furnace liner 2, a feeding port 7 opened at the upper end of the vertical furnace body 1 and communicating with the inside of the furnace liner 2, a combustion waste gas discharge pipe 8 fixedly connected to the upper end of the vertical furnace body 1, and a pressure gauge 9 and a thermometer 10 installed at the upper end of the vertical furnace body 1 and extending into the inside of the furnace liner 2. During the carbonization stage, the hawthorn kernels are put into the inside of the furnace liner 2 through the feeding port 7. The liquefied gas burner is inserted into the vertical furnace body 1 through the liquefied gas burner inlet pipe 3 to heat the furnace liner 2. The flue gas generated by the thermal decomposition of the hawthorn kernels is discharged to the condenser through the flue gas collection pipe 6. The flue gas is condensed into a liquid to obtain a preliminary extract. The waste gas generated by combustion is discharged through the combustion waste gas discharge pipe 8. The carbonized hawthorn kernel slag is discharged through the discharge slag port 5. The combustible gas in the flue gas generated by the thermal decomposition of the hawthorn kernels enters the vertical furnace body 1 through the combustible gas return pipe 4 for combustion, which can effectively save energy consumption; As Figure 3 shown, a servo motor 11 (the specific model is selected according to actual needs) is also installed in the middle of the upper end of the vertical furnace body 1, and a high-temperature resistant telescopic column 12 (which is a prior art, and the specific structure and working principle will not be described in detail here. The telescopic driving source can be selected as hydraulic drive or electric drive, and the specific driving source is selected according to actual needs) connected to the output end of the servo motor 11 is placed inside the furnace liner 2. A plurality of surrounding material scooping units 13 are fixedly connected to the lower end of the high-temperature resistant telescopic column 12, and a plurality of driving motors (the specific models are selected according to actual needs) respectively connected to each material scooping unit 13 are installed inside the lower end of the high-temperature resistant telescopic column 12. During the carbonization process, since the hawthorn kernels are all piled up inside the furnace liner 2, the heat received by the bottom layer of hawthorn kernels and the middle and upper layers of hawthorn kernels is uneven. By driving the material scooping unit 13 to move up and down through the high-temperature resistant telescopic column 12 of this embodiment, and the rotation action of the material scooping unit 13 itself, the turning of the hawthorn kernels can be realized, thereby effectively improving the heat uniformity of the hawthorn kernels, which is beneficial to the decomposition of active ingredients. Moreover, during the turning process, the gap between the hawthorn kernels is also increased, which is beneficial to the rise of flue gas and avoids blockage. Compared with the stirring and horizontal rolling actions in the prior art, the bottom turning of this embodiment can effectively inhibit the generation of a large amount of dust and lighten the burden on the purification work of the extract; As Figure 4 , 5, as shown in FIGS. 7, the hopper material unit 13 includes a flipping seat 14, a driving shaft 15 fixedly connected to the flipping seat 14 and connected to the output end of the driving motor, a telescopic groove 1401 opened on the side wall of the flipping seat 14 away from the driving shaft 15, and a porous material plate 16 fixedly connected inside the telescopic groove 1401 (the aperture of which is smaller than the diameter of the hawthorn core, and the porous structure can not only allow the flue gas to rise but also prevent the hawthorn core from falling). The specific material flipping action is as follows: First, the porous material plate 16 is located above the hawthorn core. At this time, the porous material plate 16 is driven by the driving motor to rotate to the vertical position, and then it is driven by the high-temperature resistant telescopic column 12 to move down and insert into the bottom of the hawthorn core. Before the porous material plate 16 is about to contact the bottom of the furnace liner 2, the driving motor drives the porous material plate 16 to rotate from the vertical state to the horizontal state. During this process, the porous material plate 16 can hold the hawthorn core. During the rotation of the porous material plate 16, the high-temperature resistant telescopic column 12 also moves down synchronously, so that the porous material plate 16 holds the bottom-layer hawthorn core. Then, the high-temperature resistant telescopic column 12 drives the porous material plate 16 to move up again. When the porous material plate 16 moves up above the hawthorn core, the driving motor rotates the porous material plate 16 to the vertical state again, so that the bottom-layer hawthorn core falls on the upper-layer hawthorn core. In this way, one material flipping operation is completed. By repeating the above material flipping action, the bottom-up flipping of the hawthorn core is realized, thereby effectively improving the uniform heating of the hawthorn core. Compared with the prior art, the material flipping action of this embodiment is relatively gentle. First, it will not cause a large amount of fragmentation of the carbonized hawthorn core and generate a large amount of dust. Second, it can effectively reduce the generation of noise; There is a gap of 2 - 3 cm between the flipping seat 14 and the lower end of the high-temperature resistant telescopic column 12. And a support sleeve sleeved outside the driving shaft 15 is fixedly connected to the side wall of the lower end of the high-temperature resistant telescopic column 12 (the support sleeve is used to reinforce and support the entire hopper material unit 13 to prevent the hopper material unit 13 from tilting after holding the hawthorn core). There is a gap of 2 - 5 mm between adjacent two flipping seats 14. Since the flipping seat 14 needs to rotate driven by the driving motor, in order to prevent the high-temperature resistant telescopic column 12 from hindering the rotation of the flipping seat 14, enough gaps should be left between the flipping seat 14 and the high-temperature resistant telescopic column 12. Similarly, since multiple flipping seats 14 rotate synchronously, in order not to hinder each other's rotation actions, enough gaps should also be left between adjacent two flipping seats 14. The specific values of the above gaps can be determined according to specific settings. In addition, there should also be a gap smaller than the size of the hawthorn core between the outer end of the porous material plate 16 and the inner wall of the furnace liner 2. First, it is to prevent the hawthorn core from leaking through the gap during the material flipping process due to too large a gap. Second, it is to prevent the porous material plate 16 from contacting the inner wall of the furnace liner 2 and causing wear; This embodiment uses a vertical furnace for dry distillation, which can reduce the floor area of the equipment and is also convenient for maintenance. Compared with the stirring and tumbling actions in the prior art, the bottom-up material flipping action of this embodiment can effectively inhibit the generation of a large amount of dust and also reduce the generation of noise.

[0020] The second implementation mode: Based on the first implementation mode, this implementation mode further improves the porous material plate 16 to preheat the hawthorn kernels, so as to realize the continuous progress of the carbonization process, and other parts are the same as the first implementation mode; As Figure 6 、 8 、9 shows that preheating expansion units 17 are fixedly connected to both side walls of the porous material plate 16, and the area of the preheating expansion unit 17 after expansion is smaller than the area of the porous material plate 16. The preheating expansion unit 17 includes side sealing plates 18 and high-temperature resistant corrugated telescopic sleeves 19 fixedly connected between the side sealing plates 18 and the porous material plate 16 (made of high-temperature resistant elastic materials, and the specific materials are selected according to actual needs and will not be described in detail here). The side walls of the side sealing plates 18, the high-temperature resistant corrugated telescopic sleeves 19, and the porous material plate 16 (all three are made of high-temperature resistant materials, and the specific materials are selected according to actual needs and will not be described in detail here) enclose a sealed space. A plurality of equally spaced electrostrictive rods 20 (made of electrostrictive materials) are fixedly connected between the side walls of the side sealing plates 18 and the porous material plate 16, and the remaining part of the sealed space except the electrostrictive rods 20 is filled with force-enhancing fillers 21. Most of the existing carbonization furnaces stop after carbonizing a batch of hawthorn kernels and then carbonize the next batch of hawthorn kernels. Each time a new batch of hawthorn kernels is carbonized, it needs to be reheated, resulting in a large energy consumption. In this implementation mode, before a batch of hawthorn kernels is completely carbonized, the porous material plate 16 is raised above the hawthorn kernels and the electrostrictive rods 20 are energized to make them extend, so that the preheating expansion unit 17 expands. In this way, the entire material holding unit 13 forms a disc shape close to a complete circle, thereby isolating the inside of the furnace liner 2 into upper and lower parts. Then, new hawthorn kernels are added into the furnace liner 2 through the feeding port 7 so that they fall on the expanded material holding unit 13. While adding the new hawthorn kernels, the servo motor 11 drives the material holding unit 13 to rotate slowly, so that the hawthorn kernels are evenly distributed. The heat of the lower hawthorn kernels is used to preheat the new hawthorn kernels. After the lower hawthorn kernels are cleared out, the electrostrictive rods 20 are powered off and the porous material plate 16 is rotated to pour the new hawthorn kernels down. This can not only save energy consumption, but also the initial heating temperature of the new hawthorn kernels does not start from room temperature, effectively improving the production efficiency and achieving the purpose of continuous carbonization; As Figure 10As shown in the figure, the electrostrictive rod 20 includes a plurality of alternately connected metal segments 2001 and electrostrictive segments 2002, and the length of the metal segment 2001 is greater than that of the electrostrictive segment 2002. Since the expansion rate of the electrostrictive material is limited and the bearing capacity of the preheating expansion unit 17 also needs to be considered, the electrostrictive segments 2002 are installed in an intermittent arrangement. In this way, while the preheating expansion unit 17 can expand and contract, a certain support strength can be maintained, and collapse will not occur during the preheating of the hawthorn kernels. As Figure 11 shown in the figure, the force-enhancing filling member 21 has a honeycomb mesh structure, and the force-enhancing filling member 21 is made of a high-temperature-resistant elastic metal material. The force-enhancing filling member 21 can enhance the ability of the preheating expansion unit 17 to bear the hawthorn kernels and keep the preheating expansion unit 17 and the porous material plate 16 on the same plane, so as to prevent the hawthorn kernels from falling on the preheating expansion unit 17 and causing it to tilt and the material to leak down.

[0021] Compared with the prior art, this embodiment can use the waste heat of the hawthorn kernels to preheat the new hawthorn kernels, eliminating the trouble of heating the hawthorn kernels from room temperature every time, effectively saving energy consumption, and effectively improving production efficiency, achieving the purpose of continuous dry distillation.

[0022] Combined with the current actual needs, the above-mentioned embodiment adopted in this application is not limited to this scope. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
