Description

Technical Field

[0001] This invention belongs to the field of tea polyphenol extraction technology, specifically a tea extraction device for enhancing the flavor of green tea. Background Technology

[0002] Tea contains polyphenols, which are widely used and ideal natural antioxidants. One step in tea processing is to extract polyphenols from tea leaves. Polyphenols are extracted by adding a mixed solution and chopped tea leaves, then filtering and heating to purify the product. However, existing filters often do not filter the tea leaves thoroughly enough, and the solution in the tea residue is not fully extracted, which affects the production output.

[0003] Meanwhile, patent application number 202022399767.X discloses a tea stirring and tea polyphenol extraction device, including a stirring and tea polyphenol extraction device body, a motor, a servo motor, and an air rod. This tea stirring and tea polyphenol extraction device introduces tea leaves and the required mixture into the feed port, and then the stirring rod stirs the mixture. The centrifugal force throws the mixed solution onto the first filter plate for preliminary filtration, and then the sediment falls onto the second filter plate for secondary filtration. The tea residue is slid into the extrusion chamber by the air rod contracting and driving the pulleys in the bottom plate to slide the bottom plate open. The bottom plate is then retracted into the groove, and the tea residue slides into the extrusion plate. The air rod extends and retracts, driving the extrusion plate to extrude the solution in the residue.

[0004] However, in implementing the relevant technology, it was found that the tea stirring and tea polyphenol extraction device disclosed above often has insufficient filtration during the filtration process. The solution in the tea residue is not fully extracted, which affects the production output and the extraction of tea polyphenols from the tea. After the extraction device completes the extraction of tea polyphenols and discharges the solution from the extraction device, the tea residue may adhere to the inner wall of the extraction device, which is inconvenient to clean.

[0009] Preferably, a feed inlet is fixedly connected to the top of the upper cover, a motor is rotatably connected to the center of the upper cover, and a rotating rod is rotatably connected to the output end of the motor.

[0010] Preferably, a first rotating arm is fixedly connected to the bottom end of the rotating rod, and a crushing roller is rotatably connected to the bottom end of the other end of the first rotating arm, with the outer side of the crushing roller fitting against the inside of the filter tank.

[0011] Preferably, a second rotating arm is sleeved on the outer side of the rotating rod, and a scraper is fixedly connected to the bottom end of the second rotating arm. The outer side of the scraper is disposed on the inner wall of the filter tank.

[0012] Preferably, a heating rod is slidably connected to the inside of the right side of the fixing frame, and the bottom end of the heating rod slides up and down inside the filter tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model purifies green tea by placing a filter tank inside a purification cylinder. The purification tank is then removed from the filter tank to remove tea residue and other impurities, resulting in a pure extract. The filter tank is then cleaned, which facilitates the next processing of green tea and avoids affecting its flavor and quality.

[0015] 2. This utility model places tea leaves on the inner wall of a filter tank, crushes and shears the tea leaves by squeezing, and then heats them by immersing them in a solution. The crushing and heating of the tea leaves increases the contact area between the tea leaves and the extraction solvent, improving the extraction efficiency and allowing the effective components in green tea to dissolve and be released more fully. During the heating process, the tea residue is extracted and collected through the filter tank inside the purification cylinder, preventing impurities inside the tea leaves from hindering the extraction of tea polyphenols.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6As shown, this utility model provides a tea extraction device for enhancing the flavor of green tea, including a purification cylinder 1. An extension seat 2 is fixedly connected to the outside of the purification cylinder 1. A sleeve 3 is fixedly connected to the top of the extension seat 2. A hydraulic rod 4 is slidably connected inside the sleeve 3. An extension rod 5 is fixedly connected inside the hydraulic rod 4. A sliding groove is slidably formed inside the extension rod 5. A handle 6 is slidably connected inside the sliding groove of the extension rod 5. A filter tank 7 is fixedly connected to the outside of the handle 6. The filter tank 7 slides up and down inside the purification cylinder 1. The liquid outlet on the outside of the purification cylinder 1 is used for liquid drainage. Extraction parameters, such as extraction time, temperature, and solvent type, can be adjusted according to different needs to obtain extracts with different flavor characteristics and improve the flavor quality of green tea.

[0025] Specifically, the top of the filter tank 7 is slidably connected to the top cover 8. A square groove is provided on the left side of the top cover 8. A clamping rod 15 is provided inside the square groove of the top cover 8. A fixing frame 16 is fixedly connected to the top of the clamping rod 15. A clamping plate 17 is slidably connected to the left side of the fixing frame 16. Rotating the adjusting screw 18 moves the clamping plate 17 closer to the outside of the filter tank 7. The other end of the adjusting screw 18 is clamped to the outside of the filter tank 7.

[0026] Furthermore, a collar 19 is fixedly connected to the top of the fixed frame 16, and a threaded rod 20 is rotatably connected inside the collar 19. When the threaded rod 20 is rotated, it causes the filter bucket 21, which is welded and fixed at the bottom, to slide up and down inside the filter tank 7. A filter screen 22 is fixedly connected to the top of the filter bucket 21, which is used to filter and collect the foam residue produced after the green tea is heated.

[0027] Furthermore, the top of the cover 8 is fixedly connected to the feed port 24, eliminating the need to open the cover 8 and saving processes. The center of the cover 8 is rotatably connected to the motor 9, and the output end of the motor 9 is rotatably connected to the rotating rod 10.

[0028] It is worth noting that the bottom end of the rotating rod 10 is fixedly connected to the first rotating arm 11, and the bottom end of the other end of the first rotating arm 11 is rotatably connected to the crushing roller 12. The outer side of the crushing roller 12 crushes the green tea inside the filter tank 7.

[0029] It is worth noting that a second rotating arm 13 is sleeved on the outer side of the rotating rod 10, and a scraper 14 is fixedly connected to the bottom end of the second rotating arm 13. The outer side of the scraper 14 rotates on the inner wall of the filter tank 7, which facilitates scraping the green tea residue on the inner wall of the filter tank 7.

[0030] It is worth mentioning that a heating rod 23 is slidably connected to the inside of the right side of the fixing frame 16. The bottom end of the heating rod 23 slides up and down inside the filter tank 7. By heating the solution, the temperature of the extraction solvent is increased, which promotes the dissolution and release of the effective components in the tea and improves the extraction efficiency.

[0031] Among them, motor 9 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle:

[0033] First, the staff pours green tea into the feed inlet 24 inside the top cover 8. The output end of the motor 9 drives the first rotating arm 11 on the outside of the rotating rod 10 to rotate. The first rotating arm 11 drives the outer crushing roller 12 to rotate, and the crushing roller 12 squeezes the tea leaves inside the filter tank 7. The second rotating arm 13 at the bottom of the rotating rod 10 drives the scraper 14 to rotate. The scraper 14 scrapes and crushes the tea leaves adhering to the outside of the filter tank 7. After crushing for a period of time, the hydraulic rod 4 inside the sleeve 3 at the top of the extension seat 2 retracts and slides downward, driving the outer extension rod 5 to slide downward. The filter tank 7 slides into the purification cylinder 1 and is heated. Then, the solution is introduced to raise the temperature of the extraction solvent, promoting the dissolution and release of the effective components in the tea leaves. The tea leaves and the extraction solvent are thoroughly mixed. During the green tea processing, foam residue is generated. The threaded rod 20 is rotated to slide the filter barrel 21 into the filter tank 7. The foam residue passes through the filter screen 22 and enters the filter barrel 21 for collection. After heating is completed, the heating rod 23 is lifted upward to allow the extract to cool naturally. The filter tank 7 is then slid upward from the purification cylinder 1 to remove tea residue and other impurities, resulting in a pure extract.
