Description

Technical Field

[0001] This invention relates to the field of bamboo beverage processing technology, and in particular to a method for producing green bamboo extract and its beverage. Background Technology

[0002] Bamboo, as an abundant natural resource, is widely distributed globally, especially in Asia where it has a long history of cultivation and utilization. Bamboo leaves contain a variety of bioactive components, among which flavonoids have attracted much attention due to their antioxidant, anti-inflammatory, and antibacterial properties. These flavonoids have broad application prospects in the fields of medicine, health products, and cosmetics. Traditional methods for extracting flavonoids mainly include solvent extraction and steam distillation. However, these methods have problems such as low extraction efficiency, long extraction time, large solvent consumption, and potential environmental pollution. With the advancement of technology, researchers have begun to explore more efficient and environmentally friendly extraction technologies to improve the extraction efficiency and quality of flavonoids. In recent years, compound enzyme-microwave extraction has gradually attracted the attention of researchers as an emerging extraction technology. This method combines the advantages of enzymatic hydrolysis and microwave-assisted extraction. Enzymatic hydrolysis destroys the plant cell wall, making it easier to release the target components. At the same time, microwave heating can accelerate molecular motion and improve extraction efficiency. However, in practical applications, how to effectively combine enzymatic hydrolysis and microwave extraction, and how to design efficient extraction equipment, are still problems that need to be solved. To address the aforementioned problems, this technical solution proposes a method for producing green bamboo extract and its beverage. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of low extraction efficiency, long extraction time, large solvent consumption and potential environmental pollution of traditional flavonoids, and to propose a method for producing green bamboo extract and its beverage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A green bamboo extract, comprising fresh bamboo leaves, wherein flavonoids are extracted from the bamboo leaves using a compound enzyme-ultrasonic extraction method. The specific extraction method includes the following steps: S1. Place the pre-chopped bamboo leaves into the mixing and extraction machine; S2. Use a mixing extractor to squeeze the chopped bamboo leaves to extract the juice from them; S3. Introduce the squeezed juice into the extract to extract the flavonoids in the juice and dissolve them into the extract; S4. After extraction, separate the extract containing flavonoids. The mixing and extraction machine includes a machine housing, a feeding hole on the top of the machine housing, an extraction box fixedly connected inside the machine housing, and the extract liquid placed inside the extraction box. The mixing and extraction machine also includes an extrusion component and an ultrasonic component. The extrusion component is installed on the inner wall of the top of the equipment housing and corresponds to the feeding hole. It is used to crush the chopped bamboo leaves to pulverize the bamboo leaves and squeeze out the juice. The ultrasonic component is installed inside the extraction chamber, with one side extending to the outside of the equipment body and fixedly connected to the top of one side of the equipment body. It is used to work with the compound enzyme to break down the cell walls of bamboo leaves and accelerate the dissolution of flavonoids.

[0005] In one possible design, the extrusion component includes a feed hopper fixedly connected to the inner wall of the top of the equipment housing. The opening of the feed hopper corresponds to the feeding hole. A rolling assembly is installed inside the feed hopper. The rolling assembly cooperates with the inner wall of the feed hopper to crush the chopped bamboo leaves and squeeze out the juice. One side of the rolling assembly extends into the equipment housing, and a drive motor is fixedly connected to the top of the other side of the equipment housing. The output shaft of the drive motor extends into the equipment housing and is fixedly connected to the rolling assembly. The drive motor drives the rolling assembly to crush the bamboo leaves and squeeze out the juice. The crushed bamboo leaves and juice fall into the extraction box together.

[0006] In one possible design, the rolling assembly includes a drive shaft rotatably connected to the feed hopper, a grinding roller fixedly sleeved on the drive shaft, the grinding roller cooperating with the inner wall of the feed hopper to crush bamboo leaves, one end of the drive shaft extending into the equipment housing and fixedly connected to the output shaft of the drive motor, the drive motor driving the drive shaft and the grinding roller to rotate, thereby crushing the bamboo leaves and squeezing out the juice, and the crushed bamboo leaves and juice synchronously entering the extraction box for extraction.

[0007] In one possible design, the ultrasonic component includes multiple ultrasonic transducers fixedly connected at equal intervals to the inner walls of both sides of the extraction chamber, and an ultrasonic controller fixedly connected to the top of one side of the equipment housing. The ultrasonic controller is electrically connected to the multiple ultrasonic transducers, and controls the ultrasonic transducers to generate ultrasonic waves. These ultrasonic waves, in conjunction with the complex enzymes in the extract, break down the cell walls of bamboo leaves, rapidly extracting flavonoids into the extract and improving extraction efficiency.

[0008] In one possible design, an air pump is fixedly connected to the outside of the equipment housing. The air pump's outlet extends into the extraction chamber and is fixedly connected to a multi-head nozzle. The air pump's housing is fixedly connected to the bottom inner wall of one side of the extraction chamber. The air pump's suction end is fixedly connected to an air delivery pipe. One end of the air delivery pipe is connected to an isolation component, which is fixedly connected to the other side of the equipment housing. The air pump draws external gas through the isolation component and then disperses and blows it into the extraction liquid through the multi-head nozzle, causing the extraction liquid to tumble and ensuring that the bamboo leaves, extraction liquid, and ultrasonic energy field are in full contact, thus avoiding insufficient extraction.

[0009] In one possible design, the isolation assembly includes a heating cylinder fixedly connected to the bottom of the other side of the equipment housing. One end of the gas supply pipe is fixedly connected to one end of the heating cylinder, and an isolation mesh is fixedly connected to the other end of the heating cylinder. A spiral heating ring is fixedly connected inside the heating cylinder. The spiral heating ring is electrically connected to an external power source through a wire. The isolation mesh filters impurities and dust in the gas, and the spiral heating ring heats the gas. The heated gas is blown into the extraction liquid to adjust the temperature of the extraction liquid, thereby further improving the extraction efficiency and quality of flavonoids.

[0010] In one possible design, an installation tube is fixedly connected to the inner wall of one side of the bottom of the extraction box. The bottom of the installation tube extends to the bottom of the equipment box. An installation cover is slidably fitted inside the installation tube. A support ring located above the installation cover is fixedly connected inside the installation tube. An installation ring is fixedly connected inside the installation cover. A support plate is fixedly connected to the top of the installation ring. The top of the support plate passes through the support ring and slidably fits with the support ring. A top sealing plate is fixedly connected to the top of the support plate. The top sealing plate is tightly fitted to the inner wall of the installation tube. A flow guide is fixedly connected to the bottom of the installation ring. A discharge hole is opened on the top inner wall of one side of the installation cover. A filter screen is detachably and sealed inside the discharge hole. During extraction, the top sealing plate closes the installation tube. After extraction, the installation cover is pulled to move the filter screen below the installation tube. The extract is guided through the flow guide and discharged through the filter screen. The filter screen filters out bamboo leaf residue.

[0011] In one possible design, the bottom of the mounting cover is fixedly connected to a bottom cover located below the mounting tube. The bottom cover is used to seal the mounting tube. Two limiting rods are symmetrically fixedly connected to the top of the bottom cover, located on both sides of the mounting tube. A first electromagnet ring is fixedly sleeved on the limiting rod. Two second electromagnet rings are fixedly connected to the bottom of the equipment box. The top of the limiting rod passes through the corresponding second electromagnet ring and extends into the equipment box, and slides in cooperation with the inner wall of the bottom of the equipment box. The sides of the first electromagnet ring and the corresponding second electromagnet ring that are close to each other are the N pole and the S pole, respectively. After being energized, they attract each other to position the bottom cover and the mounting cover. After being de-energized, the mounting cover can be pulled to separate the extractant.

[0012] A method for producing a beverage, comprising the green bamboo extract as described above, and further comprising the following steps: S1. The extract containing flavonoids is purified by passing it through a low-temperature membrane to remove impurities and improve the purity of the extract. S2. Mix the purified green bamboo extract with excipients, sugar and purified water according to the formula ratio, and homogenize the mixture to ensure that the beverage has a delicate taste and stable state. S3. Sterilize the prepared beverage to kill microorganisms and ensure food safety and shelf life. After sterilization, fill the beverage in a sterile or clean environment to obtain the finished beverage.

[0013] In this application, during use, fresh bamboo leaves are first chopped and fed into the hopper through the feeding hole at the top of the equipment box. The drive motor is started to rotate the transmission shaft, which in turn causes the grinding roller to rotate and crush the bamboo leaves, squeezing out the juice from the bamboo leaves. The crushed bamboo leaves and juice fall into the extraction box together. Then, an extract containing complex enzymes such as cellulase is added to the extraction box. Multiple ultrasonic transducers are activated by operating the ultrasonic controller. The ultrasonic transducers generate ultrasonic waves, and at the same time, the complex enzymes in the extract treat the crushed bamboo leaves, breaking down the plant cell walls. The ultrasonic energy field quickly extracts target components such as flavonoids into the solvent. Simultaneously, the air pump is started, and external gas enters the heating cylinder after being filtered for impurities and dust through the isolation screen. The spiral electric heating ring is energized to heat the gas. The hot gas is dispersed and blown into the extract through the gas pipe, air pump, and multi-head nozzle, causing the extract to tumble in the extraction box. This allows the bamboo leaves to tumble with the extract and fully receive ultrasonic waves. Before the extraction operation, the installation cover is moved... The extract is inserted into the installation tube, and the top sealing plate seals the top opening of the installation tube to prevent the extract from leaking out. At this time, the first electromagnet ring and the second magnetic ring are energized and attracted to each other, positioning the bottom cover and making the installation cover stably set inside the installation tube. After the entire extraction process is completed, the first electromagnet ring and the second magnetic ring are de-energized, so that the attraction between the first electromagnet ring and the second magnetic ring disappears. Then, the installation cover is pulled down, causing the top sealing plate to move down and no longer block the installation tube. At the same time, the filter screen moves to the bottom of the installation tube, and the extract flows into the installation cover. Under the guidance of the flow guide, it is discharged through the filter screen, and the residue is left in the flow guide. The filter screen can then be removed to clean the residue. After obtaining the extract mixed with flavonoids, it is purified by passing it through a low-temperature membrane. The purified green bamboo leaf extract is mixed with other prepared excipients, sugar, and purified water according to the formula ratio and homogenized. Finally, the prepared beverage is sterilized and bottled in a sterile or clean environment to obtain the finished product.

[0014] Beneficial effects: 1. Pre-treatment of pulverized bamboo leaves with complex enzymes such as cellulase can effectively destroy the plant cell wall structure, making it easier for target active ingredients such as flavonoids to break free from cell binding. Combined with the ultrasonic energy field generated by the ultrasonic vibrating plate, the active ingredients can be extracted into the extract quickly and efficiently. Compared with the traditional single extraction method, the extraction time is greatly shortened and the extraction yield per unit time is increased. 2. The air pump draws filtered and heated gas through the air delivery pipe and disperses it into the extractant in the extraction box through the multi-head nozzle. This causes the extractant to tumble violently, which in turn causes the crushed bamboo leaves to come into full contact with the extractant and the ultrasonic energy field. This avoids the problem of insufficient local extraction caused by the accumulation of bamboo leaves, further improves the extraction efficiency, ensures that the effective components in the bamboo leaves dissolve to the maximum extent, and reduces the waste of raw materials. 3. The grinding roller in the extrusion component, driven by the drive motor, crushes and grinds the chopped bamboo leaves. This not only squeezes out the juice from the bamboo leaves in advance and introduces it directly into the extraction liquid for extraction, reducing the loss of effective ingredients in subsequent extraction stages, but also crushes the bamboo leaves into finer particles, increasing the contact area with the extraction liquid and further accelerating the extraction rate. This invention solves the problems of low efficiency in traditional extraction methods. It adopts a compound enzyme-microwave extraction method, which combines ultrasound and hot air tumbling to efficiently extract flavonoids. The equipment is reasonably designed, easy to operate, and can stably extract and separate flavonoids. Subsequent purification, blending, homogenization, and sterilization processes are then used to produce beverages, improving product quality and safety and facilitating large-scale production.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] In one embodiment: Refer to Figure 1-10 A green bamboo extract, comprising fresh bamboo leaves, wherein the extract is obtained by extracting flavonoids from the bamboo leaves using a compound enzyme-microwave extraction method, the specific extraction method including the following steps: S1. Place the pre-chopped bamboo leaves into the mixing and extraction machine; S2. By using a mixing extractor to squeeze the chopped bamboo leaves, the juice in the bamboo leaves can be extracted. S3. The squeezed juice can be introduced into the extract to extract the juice and incorporate the separated flavonoids into the extract. S4. After extraction, separate the extract containing flavonoids.

[0019] like Figure 2-10 As shown, the mixing and extraction machine includes a housing 1 with a feeding hole at the top. An extraction box 6 is fixedly installed inside the housing 1, and the extract is placed inside the extraction box 6. The mixing and extraction machine also includes a pressing component installed on the inner wall of the top of the housing 1. The pressing component corresponds to the feeding hole and is used to crush the chopped bamboo leaves to extract the juice contained within them. The mixing and extraction machine also includes an ultrasonic component installed inside the extraction box 6. One side of the ultrasonic component extends to the outside of the housing 1 and connects to the top of one side of the housing 1.

[0020] like Figure 5-6As shown, the extrusion component includes a feed hopper 2 fixedly installed on the inner wall of the top of the equipment housing 1, with the opening of the feed hopper 2 corresponding to the feed hole. A rolling assembly is installed inside the feed hopper 2, engaging with the inner wall of the feed hopper 2 to crush the chopped bamboo leaves, thereby squeezing out the juice. One side of the rolling assembly extends into the equipment housing 1, and a drive motor 3 is fixedly installed on the top of the other side of the equipment housing 1. The output shaft of the drive motor 3 extends into the equipment housing 1 and connects to the rolling assembly. After the chopped bamboo leaves are fed into the feed hopper 2, the drive motor 3 is activated to drive the rolling assembly, crushing the bamboo leaves and squeezing out the juice. The crushed bamboo leaves, along with the juice, are then fed into the extraction box 6 for extraction.

[0021] like Figure 5 As shown, the rolling assembly includes a drive shaft 4 rotatably connected inside the feed hopper 2. A grinding roller 5 is fixedly sleeved on the drive shaft 4, and the grinding roller 5 cooperates with the inner wall of the feed hopper 2 for crushing bamboo leaves. One end of the drive shaft 4 extends into the equipment housing 1 and is fixedly connected to the output shaft of the drive motor 3. By starting the drive motor 3, the drive shaft 4 is rotated, which in turn drives the grinding roller 5 to rotate, thereby crushing the bamboo leaves to squeeze out the juice. The crushed bamboo leaves and the crushed bamboo leaves are then fed into the extraction box 6 for extraction of the juice and the crushed bamboo leaves.

[0022] like Figure 2 and Figure 5 As shown, the ultrasonic component includes multiple ultrasonic transducers 7 evenly spaced and fixedly installed on the inner walls of both sides of the extraction chamber 6, and an ultrasonic controller 8 fixedly installed on the top of one side of the equipment housing 1. The ultrasonic controller 8 is electrically connected to the multiple ultrasonic transducers 7. By adding the extract containing a complex enzyme such as cellulase and crushed bamboo leaves into the extraction chamber 6, the multiple ultrasonic transducers 7 can be activated by operating the ultrasonic controller 8. After activation, the ultrasonic transducers 7 generate ultrasonic waves, and the complex enzymes such as cellulase in the extract treat the crushed bamboo leaves, breaking down the plant cell walls and making it easier to release the active ingredients. Subsequently, the ultrasonic energy field generated by the ultrasonic transducers 7 can quickly and efficiently extract target components such as flavonoids into the solvent.

[0023] like Figure 4-5As shown, an air pump 9 is fixedly installed on the outside of the equipment housing 1. The air outlet of the air pump 9 extends into the extraction chamber 6 and is fixedly installed with a multi-head nozzle 10. The output shaft of the air pump 9 is fixedly connected to the inner wall of the bottom side of the extraction chamber 6. An air supply pipe 11 is fixedly installed on the air inlet of the air pump 9. One end of the air supply pipe 11 is connected to an isolation component, which is connected to the other side of the equipment housing 1. By starting the air pump 9, external gas can be drawn into the air supply pipe 11. Then, through the air pump 9 and the multi-head nozzle 10, the gas can be dispersed and blown into the extractant. At this time, the extractant can be tumbled in the extraction chamber 6, so that during the extraction of bamboo leaves, the bamboo leaves can be tumbled with the extractant, allowing the extractant and bamboo leaves to be fully exposed to ultrasonic waves.

[0024] like Figure 4 and Figure 7 As shown, the isolation assembly includes a heating cylinder 12 fixedly installed at the bottom of the other side of the equipment housing 1. One end of the gas supply pipe 11 is fixedly connected to one end of the heating cylinder 12, and an isolation net 13 is fixedly installed at the other end of the heating cylinder 12. A spiral heating ring 14 is also fixedly installed inside the heating cylinder 12, and the spiral heating ring 14 is connected to an external power source via a wire. When the air pump 9 is started to generate suction, the gas inside the heating cylinder 12 can be drawn out through the gas supply pipe 11. At this time, the external gas can enter the heating cylinder 12 through the isolation net 13, and when the gas passes through the isolation net 13, the isolation net 13 can filter out impurities and dust in the gas. At the same time, when the gas enters the heating cylinder 12, the spiral heating ring 14 can be energized to heat the gas, thereby raising the temperature of the gas blown into the extraction chamber 6. In this way, the temperature of the extract can be adjusted by blowing hot gas into the extract, thereby raising the temperature of the extract to a suitable temperature, and thus improving the extraction efficiency and quality of flavonoids.

[0025] This application can be used in the field of bamboo beverage processing technology, or in other fields applicable to this application.

[0026] In another embodiment: Reference Figure 5-11Based on the above embodiments, an improvement is made: a green bamboo extract, applied in the field of bamboo beverage processing technology. The structure of this embodiment is basically the same as the previous embodiments, except that: an installation tube 15 is fixedly installed on the inner wall of one side of the bottom of the extraction box 6, and the bottom of the installation tube 15 extends to the bottom of the equipment box 1. An installation cover 16 is tightly slidably connected inside the installation tube 15, and a support ring 21 located above the installation cover 16 is also fixedly installed inside the installation tube 15. An installation ring 18 is fixedly installed inside the installation cover 16, and a support plate 19 is fixedly installed on the top of the installation ring 18. The top of the support plate 19 passes through the support ring 21 and extends above the support ring 21, and the support plate 19 is slidably connected to the support ring 21. A top sealing plate 20 is fixedly installed on the top of the support plate 19, and the top sealing plate 20 is tightly fitted to the inner wall of the installation tube 15. A flow guide hood 22 is fixedly installed on the bottom of the installation ring 18, and the flow guide hood 22 is used to guide and transport the extract. A discharge hole is provided on the inner wall of the top of one side of the mounting cover 16. A filter screen 23 is detachably and fixedly installed in the discharge hole. The filter screen 23 is used to filter the bamboo leaf residue after extraction. When the mounting cover 16 is moved into the mounting tube 15, the top sealing plate 20 seals the top opening of the mounting tube 15, preventing the extract from being discharged through the mounting tube 15 during the bamboo leaf extraction process. After the bamboo leaf extraction process is completed, the mounting cover 16 can be pulled down, causing the top sealing plate 20 to move downwards, preventing the top sealing plate 20 from blocking the mounting tube 15. At the same time, when the mounting cover 16 moves downwards, the filter screen 23 can be moved below the mounting tube 15, allowing the extract to flow into the mounting cover 16. Then, guided by the flow guide 22, the extract can be discharged through the filter screen 23, while the residue remains in the flow guide 22. After the extract is discharged, the filter screen 23 can be removed to clean the residue in the flow guide 22.

[0027] like Figure 8-10As shown, a bottom cover 17 is fixedly installed at the bottom of the mounting cover 16, located below the mounting tube 15, to seal the mounting tube 15. Two limiting rods 24, located on either side of the mounting tube 15, are symmetrically fixedly installed at the top of the bottom cover 17. A first electromagnet ring 25 is fixedly fitted onto each limiting rod 24. Two second magnet rings 26 are fixedly installed at the bottom of the equipment housing 1. The top of each limiting rod 24 passes through the corresponding second magnet ring 26 and extends into the equipment housing 1, with the limiting rod 24 slidably connected to the inner bottom wall of the equipment housing 1. The sides of the first electromagnet ring 25 and the corresponding second magnet ring 26 closest to each other are respectively designated as N and S poles. By sliding the two limiting rods 24 to the inner bottom wall of the equipment housing 1, the bottom cover 17 can be longitudinally limited, thereby limiting the sliding movement of the mounting cover 16. Furthermore, when the mounting cover 16 is moved into the mounting tube 15 so that the bottom cover 17 closes the mounting tube 15, the first electromagnet ring 25 and the second magnet ring 26 can be energized, and the two can attract each other to position the bottom cover 17, thereby stably setting the mounting cover 16 inside the mounting tube 15.

[0028] like Figure 11 As shown, a method for producing a beverage includes the aforementioned green bamboo extract, and further includes the following steps: S1. The extract containing flavonoids is purified by passing it through a low-temperature membrane. S2. Mix the purified green bamboo leaf extract with other prepared excipients, sugar and purified water according to the formula ratio. In order to ensure that the product has a delicate taste and stable state, the mixture also needs to be homogenized. S3. The prepared beverage is sterilized to kill any microorganisms that may be present, ensuring the food safety and shelf life of the product. After sterilization, it is bottled in a sterile or clean environment to obtain the final product.

[0029] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 3, ultrasonic vibrating plate 7, ultrasonic controller 8, air pump 9, spiral heating ring 14, first electromagnet ring 25 and second magnet ring 26 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0030] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
