Description

Technical Field

[0001] This utility model relates to the technical field of juice extraction mechanisms, specifically a mugwort juice extraction mechanism. Background Technology

[0002] Currently, the extraction of mugwort juice often employs distillation, as disclosed in CN219662908U, which describes a mugwort juice extraction device, or a crushing water bath method, as disclosed in CN221969038U, which describes a mugwort juice extraction mechanism. However, distillation can only extract volatile components, and prolonged heating may alter the structure of some volatile oil components. Furthermore, the high temperature of the water bath method may cause heat-sensitive components (such as volatile oils) to volatilize or decompose. Additionally, both methods have low extraction efficiency. Therefore, there is an urgent need to design a new mugwort juice extraction mechanism to address these issues. Utility Model Content

[0003] This invention mainly provides a mugwort juice extraction mechanism, which solves the problems that distillation can only extract volatile components, and prolonged heating may cause structural changes in some volatile oil components, and the high temperature of water bath method may cause heat-sensitive components (such as volatile oils) to volatilize or decompose, and the extraction efficiency of both methods is low.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A mugwort juice extraction mechanism includes a mixing tank with a crushing zone and a stirring zone, the diameter of the crushing zone being smaller than the diameter of the stirring zone; a motor is mounted on the mixing tank, the output end of the motor extending into the mixing tank and mounted on a rotating shaft, a crushing blade is mounted on the rotating shaft located in the crushing zone, and a stirring rod is mounted on the rotating shaft located in the stirring zone; a lifting assembly is mounted on the mixing tank corresponding to the stirring zone, the lower end of the lifting assembly being provided with a stirring platform for sealing the crushing zone, the stirring platform having a through hole for the rotating shaft to pass through, the through hole having an anti-friction gap with the rotating shaft; an annular water pipe is positioned above the crushing zone, the annular water pipe having multiple water spray holes, the annular water pipe being connected to an external water supply device via a water inlet pipe; an enzyme solution inlet pipe is mounted on the mixing tank, connecting to an external enzyme solution supply device; a feeding channel is provided at the upper end of the mixing tank, and a discharge channel is provided at the lower end of the mixing tank, the discharge channel being equipped with a valve. The cell walls of Artemisia argyi are mainly composed of polysaccharides such as cellulose, hemicellulose, and pectin. Enzymatic hydrolysis utilizes a complex enzyme preparation, including cellulase, pectinase, and galactosidase, to decompose cell wall components through a specific catalytic reaction, causing cell structure rupture and releasing juice (containing polysaccharides, flavonoids, amino acids, etc.). Enzymatic hydrolysis must be carried out in an aqueous solution, with the raw material moisture content controlled between 60% and 80%. Excessive dryness inhibits enzyme activity, while excessive moisture affects subsequent solid-liquid separation. After the enzymatic hydrolysis of Artemisia argyi, any existing filtration method can be used to separate the Artemisia argyi from the water. For example, a pressure filtration mechanism using existing technology can be used, which includes a filter bag fixedly installed on the top wall of a support box, an electric push rod fixedly installed on the inner wall of the support box, and a pressure plate fixedly connected to the output end of the electric push rod. The mixing table is mainly used to assist in crushing the mugwort in the crushing chamber, preventing the mugwort from falling directly into the mixing area without being crushed. When the mugwort is crushed to a certain extent, it is opened to allow it to fall. The mixing table is equipped with anti-friction gaps, which, as long as they do not affect the rotation of the shaft and facilitate the up and down movement of the mixing table, allow the crushed mugwort fragments to fall and be carried out by the up and down movement of the mixing table and the water flow.In operation, the raw mugwort is first fed into the crushing zone of the mixing tank through the feeding channel. With the lifting assembly driving the mixing table to close the crushing chamber, the motor is started, driving the rotating shaft to rotate. The crushing blades crush the mugwort, and at the same time, the annular water pipe sprays water into the crushing zone through the spray nozzles to moisten the mugwort and assist in the crushing. After crushing, the lifting assembly is activated to lower the mixing table, allowing the crushed mugwort to fall into the mixing zone. During this process, the annular water pipe sprays water into the crushing zone through the spray nozzles to assist the mugwort fragments on the mixing table to fall more smoothly and to add water to the mixing zone, which is then used in conjunction with the subsequent enzyme solution for enzymatic hydrolysis of the mugwort. After the mugwort falls, the lifting assembly drives the mixing table to rise and reset. Then, the enzyme solution is supplied to the mixing zone through the enzyme solution feed pipe. The motor drives the rotating shaft to rotate the stirring rod, thoroughly mixing the crushed mugwort with the enzyme solution. After the enzymatic hydrolysis reaction is completed, the valve on the discharge channel is opened, and the extracted mugwort juice is discharged through the discharge channel. This structure, employing enzymatic hydrolysis at temperatures typically not exceeding 60℃, effectively extracts non-volatile substances such as polysaccharides and flavonoids from Artemisia argyi juice. It also avoids the damage to the structure of volatile oil components and heat-sensitive parts caused by prolonged heating and high temperatures, thus improving the quality and integrity of the extracted Artemisia argyi juice. Furthermore, the juice yield of enzymatic hydrolysis is more efficient than that of distillation and water bath methods. By incorporating a crushing zone and a stirring zone, along with components such as crushing blades and stirring rods, the crushing of Artemisia argyi and thorough mixing with the enzyme solution are achieved, enhancing the efficiency and effectiveness of the enzymatic hydrolysis reaction. The lifting assembly and enclosed platform ensure the rational separation and connection of the crushing and stirring zones at different stages of the process, making the entire extraction process more orderly and efficient. The inclusion of auxiliary components such as a ring-shaped water pipe and heating components provides more suitable conditions for the extraction of Artemisia argyi juice, further improving the quality and efficiency of the extraction.

[0006] Furthermore, a heating component is provided on the inner wall of the mixing tank corresponding to the mixing zone. Specifically, the optimal temperature for most enzymes is 40-60℃ (e.g., cellulase's optimal temperature is 50℃). Above 60℃, enzyme activity decreases rapidly, and below 40℃, the reaction rate slows down. Specifically, any existing heating component, such as an embedded heating wire assembly or a fluid heat-conducting assembly, can be used to heat the mixing zone as needed for the enzymatic hydrolysis reaction, providing a suitable temperature and improving the rate and efficiency of the reaction.

[0007] Furthermore, the upper side of the mixing table is designed with a conical surface. This structure allows the crushed mugwort to smoothly enter the mixing zone, reducing the accumulation of mugwort at the enclosed table and making feeding more convenient.

[0008] Furthermore, the outer diameter of the spray nozzle is smaller than the inner diameter. This structure allows the sprayed water to have a certain pressure, which can better moisten the mugwort, while also preventing external impurities from entering the annular water pipe, and providing a certain impact force when assisting the mugwort to fall.

[0009] Furthermore, the lifting assembly includes an electric cylinder mounted on the mixing tank, with the output end of the electric cylinder extending into the mixing zone and a connecting frame provided therein. The mixing platform is mounted on the connecting frame. With this structure, the electric cylinder serves as the power source, driving the closed platform to rise and fall via the connecting frame. The structure is simple, easy to control, and operates stably and reliably.

[0010] Beneficial effects: Enzymatic hydrolysis, typically performed at temperatures not exceeding 60℃, effectively extracts non-volatile substances such as polysaccharides and flavonoids from Artemisia argyi juice. It avoids the damage to the structure of volatile oil components and heat-sensitive parts caused by prolonged heating and high temperatures, thus improving the quality and integrity of the extracted Artemisia argyi juice. Furthermore, the juice yield of enzymatic hydrolysis is more efficient than that of distillation and water bath methods. By incorporating a crushing zone and a stirring zone, along with components such as crushing blades and stirring rods, the Artemisia argyi is crushed and thoroughly mixed with the enzyme solution, improving the efficiency and effectiveness of the enzymatic hydrolysis reaction. The lifting assembly and enclosed platform ensure reasonable separation and connection between the crushing and stirring zones at different stages of the process, making the entire extraction process more orderly and efficient. The inclusion of auxiliary components such as a ring-shaped water pipe and heating components provides more suitable conditions for the extraction of Artemisia argyi juice, further enhancing the quality and efficiency of the extraction.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1 , Figure 2 , Figure 3As shown, an artemisia argyi juice extraction mechanism of this embodiment includes a mixing tank 1 with a crushing zone and a stirring zone, wherein the diameter of the crushing zone is smaller than the diameter of the stirring zone; a motor 2 is mounted on the mixing tank 1, and a rotating shaft 3 is mounted inside the mixing tank 1 at the output end of the motor 2; a crushing blade 4 is mounted on the rotating shaft 3 located in the crushing zone, and a stirring rod 5 is mounted on the rotating shaft 3 located in the stirring zone; a lifting assembly 6 is mounted on the mixing tank 1 corresponding to the stirring zone, and a stirring table 7 for closing the crushing zone is mounted at the lower end of the lifting assembly 6; the stirring table 7 has openings... A through hole 8 is provided for the shaft 3 to pass through, and the through hole 8 and the shaft 3 have an anti-friction gap; a ring water pipe 9 is provided at the upper position corresponding to the crushing zone, and multiple water spray holes 10 are provided on the ring water pipe 9. The ring water pipe 9 is connected to an external water supply device through a water inlet pipe; an enzyme solution inlet pipe 11 is provided on the stirring tank 1, which is connected to an external enzyme solution supply device; a feeding channel 12 is provided at the upper end of the stirring tank 1, and a discharge channel 13 is provided at the lower end of the stirring tank 1. A valve 14 is provided on the discharge channel 13. Specifically, the cell wall of Artemisia argyi is mainly composed of polysaccharides such as cellulose, hemicellulose, and pectin. Enzymatic hydrolysis utilizes complex enzyme preparations such as cellulase, pectinase, and galactosidase to decompose cell wall components through specific catalytic reactions, causing cell structure rupture and releasing juice (containing polysaccharides, flavonoids, amino acids, etc.). Enzymatic hydrolysis must be carried out in an aqueous solution, and the moisture content of the raw material must be controlled between 60% and 80%. Excessive dryness will inhibit enzyme activity, while excessive moisture will affect subsequent solid-liquid separation. Specifically, after the enzymatic hydrolysis of Artemisia argyi, any existing filtration method can be used to separate the Artemisia argyi from the water. For example, a pressure filtration mechanism using existing technology can be used. This mechanism includes a filter screen fixedly installed on the top wall of a support box, an electric push rod fixedly installed on the inner wall of the support box, and a pressure plate fixedly connected to the output end of the electric push rod. A heating component 15 is provided on the inner wall of the mixing tank 1 corresponding to the mixing zone. The upper side of the mixing platform 7 is a conical surface 16. The outer diameter of the water spray hole 10 is smaller than its inner diameter. The lifting component 6 includes an electric cylinder installed on the mixing tank 1, and the output end of the electric cylinder extends into the mixing zone and is provided with a connecting frame. The mixing platform 7 is mounted on the connecting frame.

[0018] In use, the mugwort raw material is first fed into the crushing zone of the mixing tank 1 through the feeding channel 12. With the lifting component 6 driving the mixing table 7 to close the crushing chamber, the motor 2 is started, driving the rotating shaft 3 to rotate. The crushing blade 4 crushes the mugwort, and at the same time, the annular water pipe 9 sprays water into the crushing zone through the water spray hole 10 to moisten the mugwort and assist in the crushing. After crushing is completed, the lifting component 6 is started to lower the mixing table 7, so that the crushed mugwort falls into the mixing zone. During this process, the annular water pipe 9 sprays water into the crushing zone through the water spray hole 10. Water is added to the mixing zone to facilitate the falling of the mugwort fragments on the mixing table 7 and to aid in the subsequent enzymatic hydrolysis of the mugwort with the enzyme solution. After the mugwort falls, the lifting assembly 6 drives the mixing table 7 to return to its original position. Then, the enzyme solution is fed into the mixing zone through the enzyme solution inlet pipe 11. The motor 2 drives the rotating shaft 3 to rotate the stirring rod 5, thoroughly mixing the crushed mugwort with the enzyme solution. After the enzymatic hydrolysis reaction is completed, the valve 14 on the discharge channel 13 is opened, and the extracted mugwort juice is discharged through the discharge channel 13. This structure, using enzymatic hydrolysis, typically operates at temperatures not exceeding 60℃, effectively extracting non-volatile substances such as polysaccharides and flavonoids from Artemisia argyi juice. It also avoids the damage to the structure of volatile oil components and heat-sensitive parts caused by prolonged heating and high temperatures, thus improving the quality and integrity of the extracted Artemisia argyi juice. Furthermore, the juice yield of enzymatic hydrolysis is more efficient than that of distillation and water bath methods. By setting up a crushing zone and a stirring zone, along with components such as the crushing blade 4 and stirring rod 5, the crushing of Artemisia argyi and thorough mixing with the enzyme solution are achieved, improving the efficiency and effectiveness of the enzymatic hydrolysis reaction. The lifting assembly 6 and stirring platform 7 ensure reasonable separation and connection between the crushing and stirring zones at different working stages, making the entire extraction process more orderly and efficient. The inclusion of auxiliary components such as the annular water pipe 9 and heating assembly 15 provides more suitable conditions for the extraction of Artemisia argyi juice, further improving the quality and efficiency of the extraction.
