[0002] Tea is a common traditional beverage in people's daily lives, especially green tea, which retains its bright green color and natural, health-beneficial components, making it popular among the general public. The processing of green tea involves many important steps, including sun-drying, shaking, cooling, fixation, cutting and rolling, initial drying, wrapping and rolling, re-drying, and final drying. This complex process has led to the development of methods that extract the tea juice for brewing.

[0003] Existing tea extraction equipment typically extracts tea juice by soaking the tea leaves in water and then rotating the blades to extract the juice. However, this method cannot effectively extract all the tea juice from the brewed tea leaves, resulting in tea juice waste.

[0004] Therefore, a solution is needed. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a tea juice extraction device. It has the following beneficial effects:

[0015] This solution presents a tea juice extraction device that achieves physical extraction through a pressing device. A hydraulic rod drives the pressing frame downwards, and in conjunction with the pressing support plate, pressure is applied to the tea leaves from above, causing the brewed tea leaves to be squeezed and allowing the tea juice to seep out more fully from the tea cells. Compared to traditional paddle rotation, this method provides more comprehensive extraction and reduces tea juice residue and waste. The pressing frame surface is equipped with filter holes and reinforcing ribs. The filter holes ensure smooth filtration of tea juice, while the reinforcing ribs enhance the strength of the pressing frame, making it less prone to deformation under hydraulic pressure and ensuring stable pressing. The arc-shaped structure at the bottom of the inner heating chamber facilitates the collection of tea juice. Combined with the discharge pipe and valve, this allows for convenient collection of the extracted tea juice, improving collection efficiency and integrity. The outer casing of the tank device works in conjunction with the inner heating chamber. The inner heating chamber pre-treats the tea leaves by heating and brewing, creating an environment conducive to tea juice seepage. Subsequently, the tea leaves are pressed by the pressing device. This continuous process from brewing to pressing, compared to traditional single-stage brewing, allows for more complete tea juice extraction and increases the tea juice extraction rate.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] Example 1

[0024] Regarding the aforementioned problem: existing tea extraction equipment typically extracts tea juice by soaking the tea leaves in water and then using a rotating paddle. However, this extraction method cannot effectively extract all the tea juice from the brewed tea leaves, resulting in tea juice waste.

[0025] The solution is as follows: A tea juice extraction device includes a device body 1, which includes a base device 2, a tank device 3, and a pressing device 4. The tank device 3 is mounted on top of the base device 2, and the pressing device 4 is mounted on top of the tank device 3. The pressing device 4 includes a mounting block 5, a hydraulic rod 6, a pressing frame 7, and a driving ring 8. Two sets of mounting blocks 5 are provided, and the two sets of mounting blocks 5 are welded to the outer top of the tank device 3. The inner end of the mounting block 5 has an arc-shaped structure. The driving ring 8 and the pressing frame 7 are smoothly transitioned and integrally formed. The driving ring 8 is located at the top of the pressing frame 7. The pressing frame 7 has a cylindrical structure and the interior and top are through-type structures. Several sets of filter holes 10 are opened on the surface of the pressing frame 7. The surface of the pressing frame 7 is provided with reinforcing ribs 9, which have a cross-shaped structure. There are two sets of hydraulic rods 6. The two sets of hydraulic rods 6 are respectively installed at the bottom of two sets of mounting blocks 5. The top driving ends of the two sets of hydraulic rods 6 are respectively connected to the bottom of the driving ring 8.

[0026] Analysis of the above: The hydraulic rod 6 is used to extend and retract, driving the pressing frame 7, which is integrated with the drive ring 8, to move up and down. Tea leaves are placed inside the pressing frame 7 or on the pressing support plate 13 of the inner heating box 12. When the hydraulic rod 6 extends, the pressing frame 7 presses down, applying pressure to the tea leaves, causing the tea juice to be squeezed out through the filter holes 10 of the pressing frame 7 and the pressing support plate 13. The tea leaves are then placed back into the pressing frame 7 (if there is a large amount of tea, it can also be spread on the pressing support plate 13, with the pressing frame 7 pressing down to cover and press). Hot water is then added, overflowing onto the pressing support plate 13 and over the tea leaves. The hydraulic rod 6 is then activated, and a suitable pressure setting is applied. The pressure (adjusted according to the type and quantity of tea leaves, for example, less pressure for tender leaves and more pressure for older leaves or larger quantities) is applied. After pressing, the hydraulic rod 6 retracts and resets, causing the pressing frame 7 to move up to a suitable height for easy removal. The filter holes 10 are then cleaned of blockages, and the reinforcing ribs 9 and other structures are checked for deformation. After cleaning, the frames are reinstalled. Through physical pressing, compared to traditional paddle stirring, the tea cells are squeezed more directly, allowing the tea juice to fully seep out and reducing tea juice residue and waste.

[0027] Example 2:

[0028] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the tank device 3 includes an outer box 11 and an inner heating box 12, the inner heating box 12 is located inside the outer box 11, the outer box 11 has a cylindrical structure, and the bottom of the inner heating box 12 has an arc-shaped structure.

[0029] Analysis of the above content: Add an appropriate amount of water and tea leaves into the internal heating chamber 12, turn on the heating (if there is a matching heating function), and after completing the brewing pretreatment, start the pressing device 4 to press down. The tea juice flows through the filter hole 10 to the arc-shaped structure at the bottom of the internal heating chamber 12 and gathers. Open the valve 15, and the tea juice flows out from the discharge pipe 14 for collection. The internal heating chamber 12 first brews the tea leaves to initially release the tea juice, and then deeply extracts it through pressing, forming a continuous process and improving the tea juice extraction rate. The arc-shaped structure at the bottom of the internal heating chamber 12 naturally facilitates the gathering of tea juice at the discharge pipe 14. With the L-shaped discharge pipe 14 and valve 15, it is convenient to control the discharge and collection of tea juice and reduce residue.

[0030] Example 3:

[0031] Please see Figure 1-4 The present invention provides a technical solution based on embodiment one: a pressing support plate 13 is provided on the upper part of the inner heating box 12. The pressing support plate 13 has a circular structure and several sets of filter holes 10 are also provided on the surface of the pressing support plate 13. A discharge pipe 14 is provided at the bottom of the inner heating box 12. The discharge pipe 14 has an L-shaped structure and a valve 15 is installed inside the discharge pipe 14.

[0032] Analysis of the above content: The filter holes 10 of the pressing support plate 13 are compatible with the filter holes 10 of the pressing frame 7, ensuring that the tea juice is filtered and flows smoothly.

[0033] Example 4:

[0034] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: The base device 2 includes a base block 16, a support column 17, and a top block 18. The base block 16, the support column 17, and the top block 18 are smoothly transitioned and integrally formed. The support column 17 has a cylindrical structure and three columns are provided on its surface. The three support columns 17 are located between the base block 16 and the top block 18 and are distributed in a triangular manner. The surfaces of the base block 16 and the top block 18 are both provided with through-holes 21 and several sets of locking holes 22. The bottom of the base block 16 is provided with a lower anti-slip pad 20, and the top of the top block 18 is provided with an upper fitting ring 19.

[0035] The surface of the support column 17 is provided with several sets of weight-reducing grooves 23 distributed in a row at equal intervals. The weight-reducing grooves 23 have a U-shaped structure. Inside the weight-reducing grooves 23 are several sets of reinforcing structural blocks 24. The reinforcing structural blocks 24 have a triangular shape and hollowed-out grooves 25 inside.

[0036] Analysis of the above content: The bottom block 16, support column 17, and top block 18 are integrally formed to form a stable support structure. They are assembled and connected to the tank device 3 through the through-hole 21 and locking hole 22 (for example, the bottom of the tank device 3 is fitted with the upper fitting ring 19 of the top block 18, and the locking part is inserted into the locking hole 22 for fixation). The triangular distribution of the support column 17 enhances stability, the weight reduction groove 23 reduces the overall weight while ensuring strength, the lower anti-slip pad 20 increases the placement friction, and the upper fitting ring 19 improves the tightness of the fit with the tank device 3.

[0037] Specifically, a comparison of relevant test data and practical application data for this solution.

[0039] Data Description

[0040] Experimental conditions:

[0041] Sample: Fresh green tea leaves from the same batch (75% moisture content, 100g per group);

[0042] Traditional method: Soak in 80℃ hot water for 30 minutes, then stir with a paddle at 100r / min for 10 minutes;

[0043] This solution involves soaking the internal heating chamber in 80℃ hot water for 15 minutes, followed by pressing with a pressure of 0.2MPa for 5 minutes (pressing frame descending at a speed of 5mm / s).

[0044] Measurement index: The proportion of extracted tea juice to the total soluble tea juice in the tea leaves (the total soluble tea juice was determined by laboratory Soxhlet extraction, and each experiment was repeated 3 times and the average value was taken).

[0045] Key differences:

[0046] Traditional methods rely on water flow and stirring to allow the tea juice to seep out naturally. This method uses heat pretreatment to break down the tea cells initially, and then uses physical pressing to further squeeze the cells, causing the residual tea juice to seep out. Therefore, the extraction rate is slightly higher than that of traditional methods.

[0047] Data Validity Statement

[0048] Reasonableness:

[0049] The tea juice extraction rate was increased by 3.8%-4.5% (average 4.0%), which is consistent with the marginal improvement logic of physical pressing over traditional methods. After the tea cells are brewed with hot water, some tea juice has already seeped out. Pressing can only extract the remaining part, so the increase will not be too large, which is consistent with the technical characteristics of "small improvement".

[0050] Support for effectiveness:

[0051] Controlled variables: Except for the extraction method, the tea type, dosage, water temperature, and processing time were kept consistent to exclude other interfering factors;

[0052] Repeatability: Each experiment was repeated 3 times, and the standard deviation of the data was ≤0.5%, indicating that the results were stable;

[0053] Measurement accuracy: The tea juice volume is measured using an electronic balance with an accuracy of 0.1g. The total soluble tea juice volume is calibrated according to national standard methods, and the data error is ≤0.3%.

[0054] Practical significance:

[0055] For large-scale production, a 4% increase in extraction rate can reduce tea raw material waste by about 4%. In a production line that processes 1,000 kg of tea per day, this can save about 14.6 tons of raw materials per year (calculated over 365 days), demonstrating its technical and economic efficiency.

All components are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing tea juice extraction equipment generally extracts tea juice by soaking in water and then extracting it by rotating a paddle. However, this extraction method cannot effectively extract all the tea juice from the brewed tea leaves, resulting in tea juice waste. This utility model, through the combination of the above-mentioned components, can make the tea juice extraction more complete and improve the tea juice extraction rate.
