Description

Technical Field

[0001] The invention relates to the field of health-care tea, in particular to Patchouli Summer Tea and a preparation method thereof. Background Art

[0002] Patchouli tea was first used as a medicine to treat summer heat, dampness, dizziness, chest tightness, nausea, or general discomfort. It can also be used to prevent heatstroke. Patchouli contains aromatic volatile oils, the main component of which is patchouli alcohol, which has an aromatic stomachic function.

[0003] However, with the development of the field of Chinese herbal medicine, patchouli tea has also been improved and innovated. Nowadays, patchouli tea is more used as an important medicine for the general public to clear away heat and prevent heatstroke, eliminate dampness and relieve exterior symptoms, and promote dampness and stomach function in summer. At the same time, it can be used for heatstroke and colds, gastrointestinal disorders, nausea and vomiting, and diarrhea caused by summer heat and dampness.

[0004] The research and development direction of health tea is to improve the formula so that it can be used not only as a medicinal tea, but also as a daily tea for daily health care effects.

[0005] The invention patent with Chinese patent application number 201611137361.6 discloses a patchouli-flavored tea paste for relieving summer heat and a preparation method thereof, which relates to a health tea. The raw materials thereof are, by weight, 15-20 parts of patchouli, 12-15 parts of bamboo leaves, 10-15 parts of Uncaria rhynchophylla, 10-13 parts of Imperata cylindrica, 9-12 parts of white hyacinth, 8-12 parts of Sphagnum moss, 7-10 parts of Polygonum multiflorum, 5-8 parts of bitter melon, 3-5 parts of Gardenia jasminoides, 10-15 parts of green plum, 50-60 parts of tea leaves, 2-5 parts of honey, and 0.5-1 parts of pectinase. The specific preparation method is: (1) preliminary treatment; (2) decoction; (3) making fruit pulp; (4) making tea soup; (5) concentration; and (6) mixing. The invention discloses a patchouli-flavored tea paste for relieving summer heat, which effectively combines the nutrients in tea leaves with the nutrients in traditional Chinese medicine and green plums, and is made into a tea paste, which not only enhances the efficacy of the tea paste, but also improves the taste of the tea paste. Long-term drinking has the efficacy of relieving summer heat, cooling down and clearing away heat, and relieving heat and cooling blood. The technical solution proposed by the above invention proposes a health tea drink suitable for long-term drinking, but its preparation process involves the steps of making fruit pulp and tea soup, and then concentrating and mixing after these steps are completed. Since these steps are the stage of releasing the medicinal effect of the raw materials, re-aggregation after the medicinal effect is completely released is a very critical step. However, there is no subdivision process for this step in the invention, which easily leads to the loss of medicinal effect during the product preparation process. Summary of the invention

[0006] Therefore, in response to the above problems, the present invention proposes Patchouli Summer Tea, which solves the technical problem that other medicinal teas such as the existing Patchouli Summer Tea cannot be used as daily health teas by improving and innovating the formula.

[0012] Furthermore, a sealing protrusion is provided on one side of the upper kettle body close to the lower kettle body, and a sealing groove is provided on one side of the lower kettle body close to the upper kettle body. The sealing protrusion and the sealing groove cooperate with each other, and the vertical cross-section of the sealing groove is an arc-shaped structure.

[0013] Furthermore, the extrusion concentration equipment includes a molding extrusion plate arranged in the first molding cavity, a molding support plate arranged in the second molding cavity, a second connecting channel arranged in the lower kettle body, and a first connecting channel arranged in the upper kettle body. The first connecting channel and the second connecting channel are interconnected by a connecting hose, and a filter is provided at the opening of the second connecting channel. The first connecting channel is connected to the first molding cavity, and the second connecting channel is connected to the second molding cavity. An exhaust hole is provided on the upper kettle body, and the exhaust hole is connected to the first molding cavity.

[0014] Furthermore, the first communicating channel passes through to the inner top surface of the first molding cavity, and the molding extrusion plate is provided with a penetration hole.

[0015] Furthermore, the penetration hole penetrates the molded extruded plate.

[0016] Furthermore, the permeation holes include an upper permeation hole arranged on the upper surface of the forming extrusion plate, a lower permeation hole arranged on the lower surface of the forming extrusion plate, and a permeation channel connecting the upper permeation hole and the lower permeation hole. The aperture of the upper permeation hole is larger than the aperture of the lower permeation hole, and the vertical cross-section of the permeation hole is an inverted triangle.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are: 1. Compared with the existing medicinal tea or health tea, the advantages of the present invention are: by rearranging the ratio of each raw material and adding patchouli, patchouli is pungent and warm in nature, and enters the spleen, stomach and lung meridians, and can eliminate dampness and invigorate the spleen, dispel filth and harmonize the middle, relieve heat and release the exterior, and is mainly used for dampness blocking the spleen and stomach, abdominal distension, initial damp-heat, vomiting, diarrhea, summer-heat and dampness, fever and aversion to cold, fever and chills, chest and abdominal fullness and stuffiness, etc., and in the present invention, it is not a single effect, but can be combined with other Chinese herbal medicine ingredients in the present invention to achieve synergistic effect, complement each other to enhance the efficacy of Chinese herbal medicine, and is mainly based on tea leaves, supplemented by various effective Chinese herbal medicine ingredients, so that the present invention can be different from traditional medicinal teas, and can be used as a daily health tea for daily drinking.

[0018] 2. The preparation method of the Huoxiang Summer Tea in the present invention is also different from the preparation method of the traditional Chinese herbal tea. The reason for the difference is that different raw materials are used for preparation. For the treatment of different raw materials, in order to exert their respective maximum therapeutic effects, different preparation processes need to be adopted in a targeted manner. Step S1 in the present invention is a raw material processing process. This process does not subdivide the raw materials, that is, they are cleaned and discarded separately. It is worth noting that low-temperature distilled water is required for the cleaning process. The reason for using low-temperature distilled water is that some Chinese herbal medicines in the present invention are relatively sensitive in nature. Washing at room temperature or high temperature will cause the loss of their own effective ingredients. Therefore, cleaning with low-temperature distilled water can ensure that the components of all Chinese herbal medicines are retained to the maximum extent.

[0019] 3. Furthermore, in the present invention, the raw materials are batched and screened into the composition ABC respectively. The screening principle is that the composition ABC are components with similar specifications and textures. Separating them and then mixing them can ensure the efficiency of crushing and the uniform specifications after crushing, and the technical problem of uneven specifications of some parts, which may require extended crushing time, will not occur due to the mixing and crushing of components with inconsistent textures.

[0020] 4. In the present invention, the materials are humidified and mixed after being evenly crushed. The humidified mixing method can initially stimulate the efficacy of the medicine. At the same time, due to the crushing process in advance and then the humidification treatment, some raw materials become sticky after humidification, forming a natural adhesive, which paves the way for subsequent extrusion molding.

[0021] 5. The extrusion molding process in the present invention is the top priority in the overall development method, and it integrates the heating and concentration process. Through the improvement and innovation of this process, it can ensure that the medicinal effects of all raw materials in Huoxiang Summer Tea are retained in the finished tea to the maximum extent, and can exert the maximum therapeutic effect after consumers brew it in the later stage, and reduce the requirements in the later brewing process. For example, a very high water temperature is not required, and brewing at room temperature can fully exert the therapeutic effect and achieve the purpose of drinking as soon as brewing.

[0022] 6. The drying process in the present invention is also directly implemented by the mixing and humidifying equipment, which can ensure that there is no need to transport the raw materials and avoid the loss of effective ingredients caused during the transportation process.

[0023] 7. The present invention proposes a targeted improvement and innovative device for the processes in the development method, specifically a mixing and humidifying device. The device is adapted to steps S4, S5, and S6 in the development method. The mixing device can be used to perform the mixing and humidifying, extrusion molding, heating and concentration, and drying processes of Huoxiang Summer Tea in an one-stop manner. In these processes, the raw materials do not need to be transported, but can be directly run to the finished product output, ensuring that the efficacy will not be lost. Specifically, the crushed raw materials are placed in the second molding cavity in advance, and then distilled water is added for preliminary mixing and humidification, and then extrusion molding is performed. During the extrusion molding process, the heating and drying device starts to operate synchronously, and the upper kettle body starts to move toward the lower kettle body until the upper kettle body and the lower kettle body are fully matched together. At this time, the heating and drying device gradually increases the temperature in the extrusion molding cavity, and the molding extrusion plate moves downward and starts to enter. During the extrusion process, the humidified raw materials are shaped. At the same time, due to the continuous increase in temperature in the extrusion molding cavity, the drying process is also carried out simultaneously. During the extrusion molding process, the liquid medicine is continuously squeezed out due to the downward pressure, and the exuded liquid medicine flows downward to the second connecting channel, and then continues to flow through the first connecting channel through the connecting hose through the liquid pump on the first connecting channel, and then flows out from the first connecting channel and drips downward. In this process, the liquid medicine dripping downward passes through the penetration holes on the molding extrusion plate and drips onto the raw materials again. At the same time, with the operation of the heating and drying equipment, the extrusion molding cavity is in a high-temperature drying mode, and the liquid medicine will continue to decrease during the circulation process to achieve the purpose of concentrating the finished product. In addition, the extrusion operation of the molding extrusion plate in this process is not a one-time extrusion, but a continuous up and down reciprocating motion for cyclic extrusion operation.

[0024] 8. The penetration holes in the present invention are designed in an inverted cone shape, the purpose of which is to slow down the speed at which the liquid medicine penetrates into the raw materials. Cooperating with the drying process can make the concentration process more efficient, especially as the liquid medicine becomes thicker in the later stages, and penetrates into the raw materials in a highly concentrated state and is dried, thereby improving the quality of the finished product.
