Description

Technical Field

[0001] This utility model relates to the field of biological extraction and separation technology, specifically to a device for purifying and extracting raw pulp from medicinal and edible plants. Background Technology

[0002] Food-medicine homology plant puree is a beverage made from plants that are both food and traditional Chinese medicine, using scientific extraction techniques. Its core principle lies in preserving the active ingredients of the plants while removing harmful substances, making it convenient to drink. Food-medicine homology plant puree uses plants listed in the list of foods and medicines with the same origin, such as goji berries, astragalus, and poria cocos, possessing both nutritional and medicinal value. Food-medicine homology plant puree retains the effects of traditional Chinese herbal medicines (such as anti-oxidation and immune regulation) while meeting modern consumers' demand for convenient and safe beverages. The production process of medicinal and edible plant pulp generally includes pretreatment, extraction, separation and purification, concentration, blending and sterilization. Separation and purification are important steps in the production process of medicinal and edible plant pulp. In the existing technology, the separation and purification process involves sending the extracted plant pulp into a distillation vessel, heating and distilling it to evaporate the effective components into a gaseous state, and then condensing the gaseous state using a condenser to obtain a high-purity plant pulp. However, this method of purifying plant pulp using a distillation vessel and condenser has the following drawbacks: First, during the solvent extraction of medicinal and edible plants, the extracted plant pulp contains a certain amount of residual impurities. Directly introducing these impurities into the distillation vessel will not only affect the purity of the separated and purified plant pulp but also cause pipeline blockage, thus affecting the purification efficiency. Second, due to their simple structure, existing distillation devices use direct heating to heat the plant pulp, which can easily lead to uneven heating of the plant pulp, affecting the distillation efficiency. Therefore, it is an objective need to develop a device for purifying and extracting medicinal and edible plant pulp that has a reasonable structural design and can improve both product quality and production efficiency. Summary of the Invention

[0003] The purpose of this utility model is to provide a device for purifying and extracting medicinal and edible plant pulp with a reasonable structural design that can improve both product quality and production efficiency.

[0004] The purpose of this utility model is achieved as follows: it includes a pulp storage tank, a distillation kettle, and a condenser. A first filter and a second filter are provided between the pulp storage tank and the distillation kettle. The pulp storage tank, the first filter, the second filter, the distillation kettle, and the condenser are connected sequentially by a connecting pipe. The first filter has a first filter screen and a second filter screen installed vertically at intervals. The second filter has two sets of ceramic membrane filter components installed at intervals. A support frame is installed on the top of the second filter. A liquid distributor is provided above the support frame. Distribution pipes connected to the ceramic membrane filter components are installed at the bottom of the liquid distributor. Control valves are installed on the distribution pipes. A drive mechanism connected to the ceramic membrane filter components is installed on the support frame. A heating plate is installed in the lower part of the distillation kettle. An electric heater is installed in the distillation kettle below the heating plate. A stirring mechanism is installed in the distillation kettle above the heating plate.

[0005] Compared with existing technologies, the advantages of this device are as follows: First, this device is equipped with a first filter and a second filter at the front end of the distillation vessel. The first filter, with its first and second filter screens, can filter large particulate impurities in the plant pulp twice, reducing the impurity content of the plant pulp. The ceramic filter membrane component in the second filter can perform fine filtration of the plant pulp, thoroughly removing residual fine impurities and further reducing the impurity content of the plant pulp. The combined use of the first and second filters not only solves the problem of pipeline blockage but also reduces the impurity content in the plant pulp. Firstly, it improves the purification effect of plant pulp; secondly, it optimizes the structure of the distillation vessel by using an electric heater to heat the heating plate, which in turn heats the plant pulp, achieving uniform heating of the plant pulp. Simultaneously, the heating mechanism further enhances the uniformity and speed of heating the plant pulp, thus increasing the efficiency of heating and ultimately improving the purification production efficiency. It boasts advantages such as reasonable structural design, stable operation, high production efficiency, and high product purity, making it easy to promote and use. Attached Figure Description

Detailed Implementation

[0007] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0008] like Figures 1-2 As shown, this utility model includes a pulp storage tank 1, a distillation kettle 2, and a condenser 3. A first filter 4 and a second filter 5 are provided between the pulp storage tank 1 and the distillation kettle 2. The pulp storage tank 1, the first filter 4, the second filter 5, the distillation kettle 2, and the condenser 3 are connected sequentially by a connecting pipe 6. The first filter 4 has a first filter screen 41 and a second filter screen 42 installed vertically at intervals. The first filter screen 41 and the second filter screen 42 are made of stainless steel, with a pore size range commonly between 40 and 00 mesh. The mesh size of the first filter screen 41 and the second filter screen 42 gradually decreases. Two sets of ceramic membrane filter components are installed at intervals inside the first and second filters 5. A support frame 7 is installed on the top of the distillation vessel 5. A liquid inlet distributor 8 is provided above the support frame 7. A distribution pipe 9 connected to the ceramic membrane filter assembly is installed at the bottom of the liquid inlet distributor 8. A control valve is installed on the distribution pipe 9. A drive mechanism connected to the ceramic membrane filter assembly is installed on the support frame 7. A heating plate 21 is installed in the lower part of the distillation vessel 2. An electric heater 22 is installed in the distillation vessel 2 below the heating plate 21. The electric heater 22 is a structure used in the prior art and is used to heat the heating plate 21. The plant pulp in the distillation vessel 2 is distilled using the heating plate 21, which can improve the uniformity of heating. A stirring mechanism 23 is installed in the distillation vessel 2 above the heating plate 21.

[0009] The working process of this device is as follows: After solvent extraction, the plant pulp enters the extraction tank 1. Under the action of the delivery pump, the plant pulp in the extraction tank 1 first enters the first filter 4 through the connecting pipe 6. The first filter screen 41 and the second filter screen 42 in the first filter 4 can filter large particulate impurities in the plant pulp twice, reducing the impurity content of the plant pulp. After coarse filtration in the first filter 4, the plant pulp enters the liquid distributor 8 through the connecting pipe 6. Then, the control valve on the distribution pipe 9 is opened, and the plant pulp in the liquid distributor 6 enters the corresponding ceramic membrane filter assembly through the distribution pipe 9. The ceramic membrane filter assembly can perform fine filtration of the plant pulp. The finely filtered plant pulp permeates through the ceramic membrane filter assembly to... Impurities remain in the ceramic membrane filter assembly within the second filter 5, requiring regular cleaning or replacement. Meanwhile, the plant pulp entering the second filter 5 flows into the distillation vessel 2 through the connecting pipe 6. The electric heater 22 is powered on and heats the heating plate 21, which in turn transfers heat upwards to heat the plant pulp. The stirring action of the stirring mechanism further accelerates the heating process. After a period of heating, the effective components in the plant pulp vaporize according to their boiling points, forming steam. This steam then flows through the connecting pipe 6 into the condenser 3. After condensation in the condenser 3, a plant pulp with good purity is obtained, thus achieving purification of the plant pulp.

[0010] Furthermore, to facilitate the replacement or cleaning of the first filter screen 41 and the second filter screen 42, the first filter screen 41 and the second filter screen 42 are detachably installed inside the first filter 4. The first filter screen 41 and the second filter screen 42 can be connected by bolts or plugs as used in the prior art. A flange connection assembly 43 is provided on the first filter 4 between the first filter screen 41 and the second filter screen 42. The flange connection assembly 43 is a structure used in the prior art, mainly including two flanges installed in the middle of the first filter 4, as well as gaskets and bolts and nuts connecting the two flanges.

[0011] Furthermore, the ceramic membrane filtration assembly includes a ceramic membrane filter cartridge 51 and a central tube 52, wherein the ceramic membrane filter cartridge is an inner cavity. The ceramic membrane filter cartridge 51 is configured as a hollow cylindrical structure. An upper end plate 53 is installed at the upper end of the cartridge, and a lower end plate 54 is installed at the lower end. The upper end plate 53 is fixedly connected to the top of the second filter 5. A central tube 52 is coaxially installed inside the ceramic membrane filter cartridge 51. The upper end of the central tube 52 passes through the upper end plate 53 and the top of the second filter 5 and is rotatably connected to them. The lower end of the central tube 52 passes through the lower end plate 54 and is rotatably connected to it. A bottom plate is installed at the lower end of the central tube 52. Various materials are evenly distributed on the central tube 52 located inside the ceramic membrane filter cartridge 51. The device has multiple oblique holes 55. The drive mechanism is connected to the upper end of the central tube 52. The lower end of the distribution tube 9 extends into the interior of the upper end of the central tube 52. In use, the drive mechanism drives the central tube 52 to rotate, and the plant pulp in the distribution tube 9 enters the central tube 52. The rotating central tube 52 can evenly feed the plant pulp into the ceramic membrane filter cartridge 51 through the oblique holes 55. The ceramic membrane filter cartridge 51 can then perform fine filtration on the plant pulp. The finely filtered plant pulp permeates into the second filter 5, while impurities remain in the ceramic membrane filter cartridge 51.

[0012] Preferably, in order to ensure that the pulp in the central tube 52 enters the ceramic membrane filter cartridge 51 evenly and to prevent the backflow of plant pulp in the ceramic membrane filter cartridge 51, the oblique hole 55 is inclined downward along the axial direction of the central tube 52.

[0013] Preferably, in order to improve the filtration efficiency of the ceramic membrane filter cartridge 51 and prevent impurities from clogging it, an upper connecting rod 56 and a lower connecting rod 57 are symmetrically installed on the outside of the central tube inside the ceramic membrane filter cartridge 51. Side plates 58 are installed at the ends of the upper connecting rod 56 and the lower connecting rod 57, and brush bristles that contact the ceramic membrane filter cartridge 51 are installed on the side plates 58. A slag discharge pipe 59 extending to the bottom of the ceramic membrane filter cartridge 51 is provided, and each slag discharge pipe 59 is equipped with slag discharge... During the rotation of the valve and the central tube 52, the upper connecting rod 56, the lower connecting rod 57, the side plate 58, and the brush bristles can be driven to rotate. The rotation of the brush bristles can clean the inner wall of the ceramic filter cartridge 51 and remove the impurities adhering to the ceramic membrane filter cartridge 51. If the impurity content in the ceramic membrane filter cartridge 51 is too high after a period of use, the feeding of plant pulp into the central tube can be stopped, and then the slag discharge valve can be opened to discharge the impurities remaining in the ceramic membrane filter cartridge 51 through the slag discharge pipe 59.

[0014] Preferably, the drive mechanism includes a drive motor 510, a transmission shaft 511, a drive pulley 512, and a driven pulley 513. The drive motor 510 is a structure used in the prior art, and finished products are directly purchased according to the power required. The drive motor 510 is mounted on the top of the support frame 7. The upper end of the transmission shaft 511 is connected to the output shaft of the drive motor 510, and the lower end is rotatably mounted on the top of the second filter 5. The number of drive pulleys 512 corresponds to the number of central tubes 52. The drive pulleys 512 are mounted on the transmission shaft 511, and the driven pulleys 513 are mounted on the central tubes 52. The drive pulleys 512 and driven pulleys 513 are connected by a transmission belt 514. In use, the drive motor 510 is turned on, and the drive motor 510 drives the transmission shaft 511 and the drive pulleys 512 to rotate. The rotation of the drive pulleys 512 drives the driven pulleys 513 to rotate through the transmission belt 514, and the rotation of the driven pulleys 513 drives the central tubes 52 to rotate.

[0015] Furthermore, in order to improve the heating effect of the plant pulp and ensure the uniformity of heating, multiple heat-conducting rods 24 are evenly distributed and penetrated on the heating plate 21. The heat-conducting rods 24 can be made of stainless steel, copper or other materials.

[0016] Furthermore, to improve the condensation effect of plant pulp distillation and increase the yield of plant pulp, a gas-liquid distribution cone 25 is installed in the upper part of the distillation vessel 2. The gas-liquid distribution cone 25 is evenly distributed with multiple gas-liquid distribution holes. The gas-liquid distribution cone 25 has a cone structure that is larger at the top and smaller at the bottom. The stirring mechanism 23 is installed through the gas-liquid distribution cone 25. After the plant pulp vapor is separated by the gas-liquid distribution cone 25, the liquid of the plant pulp is prevented from being discharged with the steam. This can improve the purity of the product distillation and allow the generated steam to enter the condenser 3 evenly and stably. This is beneficial to improving the recovery rate of plant pulp. The condenser 3 can adopt the tubular condensation structure used in the prior art. The cooling medium used in the condenser 3 can be cold water or cold air.

[0017] Furthermore, a precooler 10 is provided between the distillation vessel 2 and the condenser 3. In order to better improve the condensation effect of plant pulp vapor, the precooler 10 can perform preliminary condensation of the plant pulp. The precooler 10 can be a serpentine tube cooler used in the prior art, and the cooling medium can be cold water or cold air.
