Description

Technical Field

[0001] The invention relates to the technical field of food processing, and more particularly to instant black tea with chrysanthemum indicum and a preparation device thereof. Background Art

[0002] Instant tea is a tea product that can dissolve quickly in water. It has the advantages of being convenient, fast, easy to carry and store. Instant black tea, as a type of instant tea, is made from black tea as raw material and undergoes a series of processing.

[0003] Ganhuangcao is a traditional Chinese medicinal material with multiple medicinal values ​​and health benefits. It is famous for its slightly cold nature and significant heat-clearing and detoxifying effects. It can clear heat and toxins from the body and relieve symptoms of getting angry. In the field of traditional Chinese medicine, Ganhuangcao is often used to prepare various Chinese medicine preparations, such as tea, oral liquid, etc. These preparations can give full play to the medicinal value of Ganhuangcao and provide strong protection for people's health.

[0004] In the production process of instant tea, the raw materials are prepared and produced in sequence through the process of drying and crushing, mixed extraction and concentrated drying. Among them, the mixed extraction process adopts a straight-cylinder extraction tank, which uses water or organic solvent as a medium to extract the effective ingredients of the tea under stirring. However, during the water extraction process, the saponins contained in black tea and yellow grass are prone to produce foam on the liquid surface. The presence of foam will hinder the effective transfer of heat. Even if the tank seems to be boiling violently, due to the insulating effect of the foam, the actual temperature of some upper raw materials may still be very low, failing to reach the high temperature conditions required for effective extraction. The uneven temperature will directly affect the full release of the effective ingredients in the tea, and thus affect the quality and purity of the final product.

[0005] To this end, the present application proposes an instant black tea with yellow grass and a preparation device thereof to solve the above problems. Summary of the Invention

[0006] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of the present invention is to provide an instant black tea with yellow grass and a preparation device thereof, which solves the problem of the mixing and extraction link in the production of instant tea. Since the raw materials contain saponins, foam will be generated, which easily causes the upper raw materials to be insulated, resulting in uneven temperature, affecting the release of effective ingredients in tea and product quality.

[0007] To solve the above problems, the present invention adopts the following technical solution: an instant black tea containing ganhuangcao is prepared from ganhuangcao, black tea, chrysanthemum, cogongrass root, and liquorice, wherein the weight percentage of each component is as follows: 89-95% black tea, 2.0-6.0% ganhuangcao, 1.0-2.0% chrysanthemum, 0.5-1.0% cogongrass root, and 0.3-2.0% liquorice, with the total weight being 100%. The instant black tea containing ganhuangcao is prepared by the following steps: S1, extraction: Grind the yellow grass, dark tea, chrysanthemum, Imperata root, and liquorice separately, pass through a 22-28 mesh sieve, mix according to the ratio, and put into the extraction kettle for extraction and separation. The extract is collected for later use, and the remaining material in the kettle is the residual material; S2.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present application solves the problem of mixed extraction in instant tea production by providing an instant black tea with Herba Camphoratae and a preparation device thereof. The problem that foam will be generated due to the saponin components contained in the raw materials can easily cause heat insulation of the upper raw materials, resulting in uneven temperature, affecting the release of effective ingredients in the tea and product quality is solved. When in use, the problem of foam generated on the liquid surface hindering heat transfer due to the saponin components contained in the black tea and Herba Camphoratae is solved, thereby effectively promoting heat transfer and the release of raw material components, and improving the quality of the extract.

[0034] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows.

[0035] Example 1: An instant black tea containing ganhuangcao is prepared from ganhuangcao, black tea, chrysanthemum, Imperata rhizome, and liquorice. Taking the total weight as 100%, the weight percentages of the components are as follows: 89-95% black tea, 2.0-6.0% ganhuangcao, 1.0-2.0% chrysanthemum, 0.5-1.0% Imperata rhizome, and 0.3-2.0% liquorice. The instant black tea containing ganhuangcao is prepared by the following steps: S1, extraction: Grind the yellow grass, dark tea, chrysanthemum, Imperata root, and liquorice separately, pass through a 22-28 mesh sieve, mix according to the ratio, and put into the extraction kettle for extraction and separation. The extract is collected for later use, and the remaining material in the kettle is the residual material; S2. Modification: Add 25% to 50% by weight of Cyclocarya paliurus leaf extract powder to the extract obtained in step S1, stir evenly, and then concentrate under vacuum and dry to obtain a dry extract; S3, water extraction: The remaining material from step S1 is placed in extraction tank 1, and water 6 to 14 times the weight of the remaining material is added, and a primary extraction is performed at 72°C to 85°C. Then, water 3 to 8 times the weight of the remaining material is added, and a secondary extraction is performed at 75°C to 88°C. Sonic oscillation is used in extraction tank 1 to eliminate the liquid surface foam generated by saponins in the material, thereby enhancing the heating extraction effect. The two extracts are then collected and combined, filtered through a filter until clear, and the filtrate is concentrated and dried. The dried material is pulverized to obtain a powder; S4, mixing: uniformly mixing the dry extract obtained in step S2 and the powder obtained in step S3 to prepare instant dark tea powder containing ganhuangcao.

[0036] In this embodiment, by adding high-quality raw materials such as scutellaria baicalensis and Cyclocarya paliurus leaf extract powder, the instant black tea of ​​the present invention not only significantly enhances its health benefits, such as effectively lowering blood sugar and blood lipids and improving antioxidant capacity, but also greatly enriches the taste of the black tea, making it more mellow and palatable. More importantly, the present invention innovatively adds a foam elimination step in the water extraction process. This improvement greatly improves the dissolution efficiency and extraction purity of the raw materials. Therefore, compared with products obtained by conventional processing, the instant black tea of ​​the present invention shows significant advantages in retaining the raw material components and improving the activity.

[0037] Example 2, please refer to Figures 1-10, a preparation device for instant black tea with yellow grass, step S3 includes an extraction tank 1; the extraction tank 1, the internal sealing device; a drive motor 2, fixedly installed at the top middle part of the extraction tank 1; a rotating shaft 3, vertically rotatably installed at the middle part of the extraction tank 1, and one end extending to the outside is fixedly connected to the output end of the drive motor 2; a stirring assembly 4, installed at the middle and lower part of the rotating shaft 3, for heating and stirring the instant black tea raw materials placed in the extraction tank 1; four magnet strips 5, which are provided and equidistantly installed at the upper part of the rotating shaft 3; a sleeve 6, which is sleeved on the upper outer part of the rotating shaft 3; a floating sleeve assembly Part 7 is installed on the upper part of the sleeve 6 and is used to adjust the height of the sleeve 6 according to the change of the water level within the range; four oscillating tuning forks 8 are provided, and the fork handles are equidistantly installed in a ring shape in the middle of the sleeve 6; an extended fork arm 9 is provided at the fork arm part of the oscillating tuning fork 8, and the inward end of the extended fork arm 9 is connected to the fork arm part of the oscillating tuning fork 8 through a threaded connection part 10; a knocking component 11 is installed at the bottom of the sleeve 6 and is used to regularly knock on the side of the fork arm part of the oscillating tuning fork 8; a water solvent 12 is provided inside the extraction tank 1, and the lowest water level of the injected water solvent 12 needs to immerse the highest part of the oscillating tuning fork 8.

[0038] By driving the rotating shaft 3 and stirring assembly 4 with the driving motor 2, the instant black tea raw material and aqueous medium 12 contained in the extraction tank 1 can be efficiently heated and stirred, thereby improving the efficiency of water extraction. Furthermore, the extraction tank 1 is provided with a sleeve 6, an oscillating tuning fork 8, and an extending fork arm 9. First, a floating sleeve assembly 7 is used to automatically adjust the floating height of the sleeve 6, oscillating tuning fork 8, and extending fork arm 9 according to changes in the water level in the extraction tank 1. This adaptive mechanism ensures that the oscillating tuning fork 8 always remains at the upper water level (the water level after the aqueous medium 12 and the raw materials are mixed). Subsequently, the striking assembly 11 is used to regularly strike the raw material, generating sound waves (a tuning fork transmits sound waves faster in water than in air), thereby exerting effective sonic vibrations. These sound waves help to destroy the cell walls of the instant black tea raw material in the upper portion. Furthermore, the sound waves and vibrations can eliminate foaming caused by saponins contained in the black tea and the herb. This not only promotes uniform and effective heat transfer and the release of the raw material's active ingredients, but also improves the quality of the extract.

[0039] Further, see Figure 3-Figure 5 The stirring assembly 4 includes: a matching sleeve 401, which is provided in multiple pieces and is equidistantly installed on the middle and lower part of the rotating shaft 3; a hollow ring plate 402, which is equidistantly installed on the outside of the matching sleeve 401, and a resistance heating tube 403 is buried inside the hollow ring plate 402; an outer ring clamp 404, which is installed on the front and back sides of the hollow ring plate 402.

[0040] By setting the matching sleeve 401, the hollow ring plate 402 and the resistance heating tube 403, and utilizing the resistance heating tube 403 buried inside the hollow ring plate 402 and the hollow structure of the hollow ring plate 402, during the stirring process, the mixed liquid with the water solvent 12 and the raw material passes through the hollow space in the middle of the hollow ring plate 402, prompting the instant black tea raw material to be formed in each layer of the hollow ring plate 402 to drive the stirring, forming a separated flow effect, so that the heating surface of the mixed liquid is larger, the heating speed is faster, the heat distribution is also uniform, the release of the effective ingredients in the raw materials is promoted, and the extraction efficiency is improved. Among them, the installation of the outer ring clamp 404 enhances the structural strength and stability of the hollow ring plate 402, so that the hollow ring plate 402 can remain stable during high-speed rotation, extend its service life, and reduce the frequency of maintenance and replacement.

[0041] Further, see Figure 3 、 Figure 4 and Figure 8 Four long slide grooves 13 are equidistantly provided on the upper side of the inner wall of the extraction tank 1 in a ring shape. A sliding block 14 is slidably connected in each of the long slide grooves 13. An inward end of the sliding block 14 is fixedly connected to a fixing hole 15. The fixing hole 15 is snap-fitted to the outward end of the extended fork arm 9, and a positive magnet 16 is installed on the outward side of the sliding block 14.

[0042] By providing the long slide groove 13, the sliding block 14 and the fixing hole 15, the sliding block 14 and the fixing hole 15 are used, so that the oscillating tuning fork 8 connected to the extended fork arm 9 can be fixed on the outside, providing stable external support for the oscillating tuning fork 8, avoiding displacement or damage caused by vibration or stirring during the operation of the extraction tank 1, ensuring the optimal position of the oscillating tuning fork 8 in the extraction tank 1, and helping to optimize the propagation path and efficiency of the sound wave, thereby improving the sound wave auxiliary effect on the foaming of the instant black tea raw material, and the sliding block 14 slides in the long slide groove 13, which can make the up and down displacement of the sleeve 6 and the floating sleeve assembly 7 more stable.

[0043] Further, see Figure 2 The outer side of the extraction tank 1 is provided with an outer partition shell 17, and the outer partition shell 17 and the extraction tank 1 are sealed. A hot air inlet 18 is provided on one side of the outer partition shell 17. Hot air or steam can be introduced into the sealed space between the outer partition shell 17 and the extraction tank 1 through the hot air inlet 18 to perform interlayer heating on the extraction tank 1. Combined with the internal heating of the internal stirring component 4, the heating efficiency is improved, which is conducive to the full dissolution and release of the effective ingredients in the instant black tea raw materials. The sealing setting between the outer partition shell 17 and the extraction tank 1 effectively reduces heat loss, enhances the heat preservation effect, and helps to maintain a stable temperature environment during the extraction process, thereby improving the extraction efficiency and product quality.

[0044] Further, see Figure 2 and Figure 8 A lightweight sealing ring 19 slides between the outer bulkhead 17 and the extraction tank 1, and a negative magnet 20 is installed on the inner wall of the lightweight sealing ring 19. By arranging the lightweight sealing ring 19 and the negative magnet 20, the hot air in the space between the outer bulkhead 17 and the extraction tank 1 can be provided more accurately. Specifically, on the one hand, the oscillating tuning fork 8 and the extended fork arm 9 are floated by the floating sleeve assembly 7, and on the other hand, the oscillating tuning fork 8 and the extended fork arm 9 are also positioned and moved by the long slide groove 13, the sliding block 14 and the fixed hole 15. During this positioning movement, due to the movement of the sliding block 14, the positive magnet 16 connected to its outside is magnetically attracted by the negative magnet 20 on the lightweight sealing ring 19 in the outer bulkhead 17 separated by the thick wall of the extraction tank 1, so that the sliding block 14 and the lightweight sealing ring 19 move synchronously. Since the lightweight sealing ring 19 moves up and down, the volume of the space between the outer bulkhead 17 and the extraction tank 1 can be changed, and then the volume of hot air injected can be accurately determined according to the specific water level in the tank, saving some energy consumption.

[0045] Example 3, please refer to Figure 6 and Figure 7 The floating sleeve assembly 7 includes: a lightweight hollow plate 701, which is provided with four, and the inward end is equidistantly annularly installed on the upper part of the sleeve 6; a floating ball 702, which is installed on the outward end of the lightweight hollow plate 701; and a heat-insulating ball layer 703, which is arranged at the bottom of the floating ball 702.

[0046] By providing the casing 6, the lightweight hollow plate 701, and the floating balls 702, the lightweight hollow plate 701, with its lightweight and hollow structure, connects to the casing 6. The floating balls 702 connected to the plate provide buoyancy for the casing 6 to float on the aqueous medium 12, and the buoyancy can be adjusted within a certain range according to the water level. Furthermore, the provision of multiple floating balls 702 is also key to ensuring the stable floating of the casing 6. Furthermore, a heat-insulating ball layer 703 is added to the bottom of the floating ball 702 to prevent damage to the floating ball 702 caused by the high temperature of the aqueous medium 12. The top of the floating ball 702 also has a heat-insulating ball layer 703 (not shown), but the bottom part is subjected to the greatest heat. Furthermore, since the movement of the floating ball 702 is related to the water level after the aqueous medium 12 and the raw materials are mixed, this movement can intuitively reflect the changes in the liquid level in the tank. A sensor (not shown) can be installed on the floating ball 702, and in conjunction with a control system, it can provide the operator with intuitive information on the liquid level in the tank, facilitating the adjustment of the addition of the aqueous medium 12.

[0047] Further, see Figure 6 、 Figure 9 and Figure 10The knocking assembly 11 includes: four slots 1101, which are equidistantly annularly opened at the lower part of the sleeve 6; four torsion spring knocking plates 1102, and one end facing inward is rotated and installed in the middle of the slot 1101; and a knocking iron ball 1103, which is installed at the top of the other end of the torsion spring knocking plate 1102.

[0048] By setting a slot 1101, a torsion spring striking plate 1102 and a striking iron ball 1103, utilizing the slot 1101 opened at the lower part of the sleeve 6, and assembling a resilient torsion spring striking plate 1102 in the slot 1101, and installing the striking iron ball 1103 thereon, a striking structure is provided for striking the oscillating tuning fork 8.

[0049] Furthermore, the knocking assembly 11 also includes: a hollow tube 1104, which is installed at the bottom of the sleeve 6 and has a hollow structure in the middle; four inner column cavities 1105, which are equidistantly annularly opened on the inner wall of the hollow tube 1104; a magnetic slide 1106, which is slidably arranged inside the inner column cavity 1105, and the inward end is a magnetic head; a fiber rope 1107, one end of which is connected to the outward end of the magnetic slide 1106, and the other end passes through the hollow tube 1104 and is connected to the bottom of the torsion spring knocking plate 1102.

[0050] By setting the hollow tube 1104, the inner column cavity 1105, the magnetic sliding column 1106 and the fiber rope 1107, the hollow tube 1104 is installed at the bottom of the sleeve 6, and the inner column cavity 1105 is opened in the hollow tube 1104. During the rotation of the rotating shaft 3, the magnet insert 5 thereon will rotate synchronously. When the magnet insert 5 rotates to the position of the inner column cavity 1105, the magnetic head of the magnetic sliding column 1106 will be attracted, and then slide inward in the inner column cavity 1105. In the process of inward movement, the connected fiber rope 1107 will be pulled, and then the torsion spring knocking plate 1102 connected to the other end of the fiber rope 1107 will be pulled. After the iron insert 5 rotates out of the position of the inner column cavity 1105, the magnetic sliding column 1106 is no longer affected by the suction effect and begins to recover. At this time, there is no pulling force of the fiber rope 1107, and the rebound of the torsion spring knocking plate 1102 will hit the side of the oscillating tuning fork 8 to generate sound waves and vibrations. On the one hand, the knocking action helps to break up the agglomerates in the upper part of the raw materials that flow to this position, enhance the stirring effect, and promote the full dissolution and release of effective ingredients. On the other hand, the saponins contained in black tea and yellow grass produce foam on the liquid surface, which can be broken at intervals so that heat transfer is not hindered, heating is evenly distributed up and down, and the effect of water extraction operation is improved.

[0051] For further information, see Figure 9 and Figure 10The interior of the hollow tube 1104 is provided with four through holes in an equidistant ring shape, and the through holes are connected to the inner column cavity 1105. Wear-resistant and waterproof sealing sleeves 1108 are installed in the through holes, and a fiber rope 1107 slides inside the wear-resistant and waterproof sealing sleeve 1108. The setting of the wear-resistant and waterproof sealing sleeve 1108, on the one hand, effectively prevents the high temperature or liquid inside the extraction tank 1 from leaking into the inner column cavity 1105 through the through holes, causing damage to the magnetic sliding column 1106 and other components, and on the other hand, reduces the wear of the fiber rope 1107, extends the service life of the fiber rope 1107, and reduces the replacement frequency and maintenance cost.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
