Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine processing and application technology, specifically relating to a Buddha's Hand tea bag and its preparation method. Background Technology

[0002] Buddha's Hand, or Citrus medica L. var. sarcodactylis Swingle, is the dried fruit of this plant, belonging to the Rutaceae family. It is harvested in autumn before the fruit turns yellow or when it has turned yellow, then longitudinally sliced ​​into thin pieces and sun-dried or dried at low temperature. Its characteristics are as follows: The fruit consists of oval or ovate slices, often wrinkled or curled, 6–10 cm long, 3–7 cm wide, and 0.2–0.4 cm thick. The apex is slightly wider, often with 3–5 finger-like lobes, while the base is slightly narrower, sometimes showing a fruit stalk scar. The outer skin is yellowish-green or orange-yellow, with wrinkles and oil dots. The pulp is pale yellowish-white or pale yellow, scattered with uneven linear or dotted vascular bundles. It is hard and brittle, becoming pliable when moist. It has a fragrant aroma and a slightly sweet taste followed by a bitter aftertaste. [Properties and Channels Entered] Pungent, bitter, sour, warm. Enters the Liver, Spleen, Stomach, and Lung channels.

Functions and Indications

[0003] Currently, Buddha's Hand citron is mostly available on the market in the form of prepared medicinal slices. The processing methods for Buddha's Hand citron slices are recorded in the processing standards for prepared medicinal slices of various provinces and cities. Some provincial processing standards also include methods for processing Buddha's Hand flowers. Regardless of which province's processing standard is used, the final Buddha's Hand citron or Buddha's Hand flower slices must be decocted in water for oral administration, which is extremely inconvenient.

[0004] Tea bags originated as a type of tea, and their inventor is generally attributed to Thomas Sullivan, a tea merchant in New York, USA. With technological advancements and societal progress, tea bags have expanded into three major industries: tea beverages, health products, and medicinal teas. They offer the benefits of enjoying tea while also providing health and wellness. Due to their convenience and portability, tea bags have become a current health trend. On February 6, 2018, the Standardization Administration of China published the national standard GB / T 24690-2018 for tea bags, imposing strict restrictions on their production and sale.

[0005] Regarding Buddha's Hand Tea, existing technology records the following: Yongchun Buddha's Hand Tea, also known as Citron or Snow Pear, is called "Golden Buddha's Hand" because of its resemblance to a Buddha's hand and its preciousness surpassing even gold. It is mainly produced in the high-altitude areas of Sukeng, Yudou, and Guiyang townships in Yongchun County, Fujian Province, at elevations of 600 to 900 meters. It is made from the tips of the Buddha's Hand tea tree variety and is a unique and renowned Fujian oolong tea. There are two varieties of Buddha's Hand tea trees: red bud and green bud (distinguished by the color of the spring buds), with red bud being considered superior. The fresh leaves are large, oval, and palm-sized, with thick leaf flesh. Buds sprout in late March and are harvested in mid-April, with harvesting occurring in all four seasons, and spring tea accounting for 40%. Legend has it that this Buddha's Hand Tea was obtained by a monk in southern Fujian who grafted tea buds onto a Buddha's Hand citron. Its leaves resemble those of the Buddha's Hand citron, and the tea has a unique "Buddha's Hand flavor." Ultimately, it is a tea product, not a medicinal herb from Buddha's Hand presented as tea. Existing technologies also disclose techniques for making Buddha's Hand tea for brewing, but these mostly involve combining Buddha's Hand with other Chinese medicinal herbs. There are few records of using Buddha's Hand alone as a tea bag in existing technologies. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tea bag made solely from Buddha's Hand citron and its preparation method.

[0007] This invention is achieved through the following technical solution:

[0008] A type of Buddha's Hand tea bag includes a packaging bag and Buddha's Hand tea slices. The packaging bag is made by folding and gluing an inner thin sheet. The Buddha's Hand tea slices are filled inside the packaging bag. The total weight of the Buddha's Hand tea slices is 3-6g, and the length of each slice is 1.2-1.5cm, and the width is 0.6-1.2cm. The moisture content of the Buddha's Hand tea slices is 6-8%. The inner thin sheet is rectangular, with a length of 15cm and a width of 6.6cm. Each Buddha's Hand tea slice has several perforated holes, which penetrate the entire slice. The diameter of each perforated hole is 0.3-0.5mm, and the density of perforated holes is 6-8 per cm. 2 .

[0009] The Buddha's Hand slices mentioned above are prepared by the following method:

[0010] (1) Buddha's Hand Purification: Take the raw medicinal material and remove impurities and moldy raw medicinal material by manual selection to obtain purified Buddha's Hand.

[0011] (2) Spray water to moisten: Place the cleaned Buddha's Hand in a bamboo tray and spray water mist onto the cleaned Buddha's Hand with a spraying device. After spraying water, wrap the bamboo tray with plastic sheet and let the cleaned Buddha's Hand moisten in the bamboo tray for 2-4 hours. Remove the plastic sheet when the humidity inside and outside the cleaned Buddha's Hand is consistent to obtain moistened Buddha's Hand.

[0012] (3) Drilling: Using mechanical drilling, water-permeable holes are made in the stale Buddha hand. The water-permeable holes are perpendicular to the outer skin of the Buddha hand and penetrate through the Buddha hand. After drilling, a perforated Buddha hand is obtained.

[0013] (4) Shredding: The perforated Buddha's Hand is cut into shreds of a preset width using a shredding machine to obtain perforated Buddha's Hand shreds;

[0014] (5) Cutting: The perforated Buddha's hand shreds are further cut into small segments of a preset length using a shredder to obtain perforated Buddha's hand shreds;

[0015] (6) Drying: Dry the perforated Buddha-shaped material with hot air at a temperature of 60-70℃ until the preset moisture content is reached, and then stop drying to obtain the dried Buddha-shaped material.

[0016] (7) Remove ash: Use sieving or air separation to remove the fine powder from the dried Buddha's Hand pieces to obtain Buddha's Hand slices.

[0017] Preferably, the packaging bag is triangular-conical in shape; it also includes an outer packaging bag, which is made of waterproof sheet material, and the outer packaging bag is placed inside the inner packaging bag. The length of the outer packaging bag is 8-13cm and the width is 5-10cm. This type of Buddha's Hand tea bag is prepared by the following method:

[0018] (1) Packaging bag making: Take the inner layer sheet and fold it to divide the first long side of the inner layer sheet into four equal segments, namely segments A, B, C and D. Divide the second long side into two equal segments, namely segments E and F. Glue segments A and B together, segments C and D together, and segments E and F together. After gluing, a triangular cone-shaped packaging bag is formed, wherein segments A, B, C and D are located on the first side of the triangular cone; segments E and F are located on the second side of the triangular cone; the intersection of segments A and B is on the first side of the triangular cone. The line segment between the endpoints of segment E on one side of the long side is located on the third side of the triangular pyramid; the line segment between the intersection of segment A and segment B and the midpoint of the first long side is located on the fourth side of the triangular pyramid; the line segment between the intersection of segment C and segment D and the endpoint of segment F on one side of the first long side is located on the fifth side of the triangular pyramid; the line segment between the intersection of segment C and segment D and the midpoint of the first long side is located on the sixth side of the triangular pyramid; a filling port is reserved between the first and second wide sides of the inner layer sheet; this type of packaging bag has ample internal space and can better adapt to the irregular characteristics of Buddha's Hand slices;

[0019] (2) Measuring and bagging: Weigh the Buddha's Hand slices of the preset weight in a sterile operating room and fill them into the prepared packaging bag through the filling port by means of machinery or manual means; After filling, glue the first and second wide edges on the inner layer sheet together; After gluing, if there is extra space in the packaging bag, the gas can be discharged by squeezing so that the volume of the packaging bag is reduced.

[0020] (3) Making the outer packaging bag: Take a waterproof sheet material and cut it into a rectangle. Fold the two ends of the rectangular sheet material along the axis at 1 / 4 and 3 / 4 of the length of the long side to the same side. After folding, glue the two long sides of the sheet material together to make the outer packaging bag. The two long sides of the sheet material are sewn together to form the two wide sides of the outer packaging bag. The axis at 1 / 4 and 3 / 4 of the length of the long side is the two long sides of the outer packaging bag. Leave a filling opening between the two wide sides of the sheet material.

[0021] (4) Packaging: Insert the packaging bag containing Buddha's Hand tea slices into the outer packaging bag through the filling port, and then seal the filling port to obtain Buddha's Hand tea bag.

[0022] Preferably, the packaging bag is rectangular; it also includes a moisture-proof layer, which consists of an outer sheet with the same shape as the inner sheet and a moisture-proof baffle. The outer sheet is sewn to both sides of the packaging bag, ensuring an opening is left at the same end. The moisture-proof baffle is a narrow strip cut from a waterproof sheet material, with both ends inserted into two openings and movably positioned between the outer and inner sheets. The difference between the width of the outer sheet and the width of the moisture-proof baffle is 0.2-0.3 cm, and the difference between the length of the outer sheet and the length of the moisture-proof baffle is 0.2-0.3 cm. A pull-out ring is also provided at the center point of the moisture-proof baffle. This type of Buddha's Hand tea bag is produced by the following method:

[0023] (1) Packaging bag making: Take the inner layer sheet and fold both ends of the inner layer sheet along the axis at 1 / 4 and 3 / 4 of the long side to the same side of the inner layer sheet respectively; after folding, glue along the two long sides of the inner layer sheet to make the packaging bag; sew the two long sides of the inner layer sheet together to form the two long sides of the packaging bag; the axis at 1 / 4 and 3 / 4 of the long side is located on the two wide sides of the packaging bag; leave a filling port between the two wide sides of the inner layer sheet;

[0024] (2) Measuring and bagging: Weigh the Buddha's Hand slices of the preset weight in a sterile operating room and fill them into the prepared packaging bags through the filling port by means of machinery or manual means; after filling, glue the two wide edges on the inner layer of the thin slices together.

[0025] (3) Moisture-proof layer setting: Take the outer thin sheet, wrap the outer thin sheet and sew it to the packaging bag along the long side of the packaging bag. Leave an insertion port at one end of the two short sides of the outer thin sheet. There are two insertion ports, which are located on both sides of the packaging bag respectively. Fold the moisture-proof baffle along the center line of the length direction and attach a pull ring on the center line. Then insert the two ends of the moisture-proof baffle into the inner thin sheet and the outer thin sheet through the two insertion ports respectively to obtain Buddha's Hand tea bag.

[0026] The inner and outer sheets mentioned above are made of any one of corn fiber, non-woven fabric, and filter paper.

[0027] The aforementioned waterproof sheet material is either kraft paper or oil paper.

[0028] The aforementioned packaging bag is also equipped with a carrying strap, which is located at any corner of the bag and has a length of 4-6 cm.

[0029] Preferably, the bonding method in this invention is thermal bonding or adhesive bonding.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) The technology of tea bags was applied to Buddha's Hand for the first time, so that users who use it to treat liver and stomach qi stagnation, chest and rib pain, epigastric fullness, poor appetite and vomiting can brew Buddha's Hand like drinking tea bags, which greatly facilitates patients.

[0032] (2) In the process of processing Buddha's Hand slices, the processing method of first cutting into shreds and then into segments is adopted so that the Buddha's Hand slices used for tea bags are as small as possible, so that the effective components can be extracted more easily during the brewing process, thereby giving full play to the efficacy of the medicine.

[0033] (3) In the process of processing Buddha's Hand slices, a perforation method is adopted to open water-permeable holes on the Buddha's Hand slices. When brewing, the permeable holes further increase the contact area between water and medicinal materials, thereby further allowing the effective components in the medicine to be extracted and utilized as much as possible, thus maximizing the utilization efficiency of the medicinal materials.

[0034] (4) The present invention also includes a moisture-proof layer or outer packaging bag. By setting the moisture-proof layer or outer packaging bag, the Buddha's Hand tea bag can be prevented from absorbing water and becoming moldy under natural conditions, which will affect the effect of use. The moisture-proof layer is set to be movable and has a pull ring, which makes it convenient for users to pull out the kraft paper strip in the moisture-proof layer before brewing, thus making it extremely convenient to use.

[0035] (5) The packaging bags, moisture-proof layers and outer packaging bags of the present invention are all made of environmentally friendly materials. They will not affect the performance of the medicinal materials after packaging. After use, they can also decompose quickly without causing secondary pollution, which is in line with the green and environmentally friendly production concept.

[0036] (6) The moisture content of the Buddha's Hand tea bag of the present invention is controlled at 6-8%, which is higher than that of similar products of the same weight. In addition, the Buddha's Hand tea bag with a moisture content of 6-8% absorbs water faster when brewing, and the extraction rate of its effective ingredients is also faster.

Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited by the embodiments.

[0041] Example 1

[0042] A type of Buddha's Hand tea bag includes a packaging bag and Buddha's Hand tea slices. The packaging bag is made by folding and gluing an inner thin sheet. The Buddha's Hand tea slices are filled inside the bag. The total weight of the Buddha's Hand tea slices is 3g. The length of each slice is 1.2-1.5cm and the width is 0.6-1.2cm. The moisture content of the Buddha's Hand tea slices is 6%. The inner thin sheet is rectangular, with a length of 15cm and a width of 6.6cm. Each Buddha's Hand tea slice has several perforated holes, which penetrate the entire slice. The diameter of each perforated hole is 0.3mm, and the density of perforations is 8 per cm. 2 The packaging bag is also equipped with a carrying strap, which is located at any corner of the bag and is 4cm long.

[0043] The Buddha's Hand slices mentioned above are prepared by the following method:

[0044] (1) Buddha's Hand Purification: Take the raw medicinal material and remove impurities and moldy raw medicinal material by manual selection to obtain purified Buddha's Hand.

[0045] (2) Spray water to moisten: Place the cleaned Buddha's Hand in a bamboo tray and spray water mist onto the cleaned Buddha's Hand with a spraying device. After spraying water, wrap the bamboo tray with plastic sheet and let the cleaned Buddha's Hand moisten in the bamboo tray for 2-4 hours. Remove the plastic sheet when the humidity inside and outside the cleaned Buddha's Hand is consistent to obtain moistened Buddha's Hand.

[0046] (3) Drilling: Using mechanical drilling, water-permeable holes are made on the sludge-dampened Buddha hand according to the preset hole diameter and density. The water-permeable holes are perpendicular to the outer skin of the Buddha hand and penetrate through the Buddha hand. After drilling, a perforated Buddha hand is obtained.

[0047] (4) Shredding: The perforated Buddha's Hand is cut into shreds of a preset width using a shredding machine to obtain perforated Buddha's Hand shreds;

[0048] (5) Cutting: The perforated Buddha's hand shreds are further cut into small segments of a preset length using a shredder to obtain perforated Buddha's hand shreds;

[0049] (6) Drying: Dry the perforated Buddha-shaped vessel with hot air at 70°C until the preset moisture content is reached, and then stop drying to obtain the dried Buddha-shaped vessel.

[0050] (7) Remove ash: Use sieving to remove the fine powder from the dried Buddha's Hand pieces to obtain Buddha's Hand slices.

[0051] The packaging bag is triangular-conical in shape and made of non-woven fabric; it also includes an outer packaging bag, which is made of a waterproof sheet material, namely kraft paper; the outer packaging bag is placed inside the inner packaging bag, and the outer packaging bag is 8cm long and 5cm wide. This type of Buddha's Hand tea bag is produced by the following method:

[0052] (1) Packaging bag production: Take the inner layer sheet and, through processes such as... Figure 1 The folding method shown divides the first long side (12) of the inner sheet into four segments, namely A (3), B (4), C (5), and D (6), and the second long side (11) into two segments, namely E (1) and F (2). Segments A and B are glued together, segments C and D are glued together, and segments E and F are glued together. After gluing, a triangular cone-shaped packaging bag is formed. The structure of the packaging bag is as follows: Figure 2 As shown; among them, segments A, B, C and D are located on the first side of the triangular pyramid; segments E and F are located on the second side of the triangular pyramid; the line segment (7) between the intersection of segments A and B and the endpoint of segment E on the first long side is located on the third side of the triangular pyramid; the line segment (13) between the intersection of segments A and B and the midpoint of the first long side is located on the fourth side of the triangular pyramid; the line segment (8) between the intersection of segments C and D and the endpoint of segment F on the first long side is located on the fifth side of the triangular pyramid; the line segment (14) between the intersection of segments C and D and the midpoint of the first long side is located on the sixth side of the triangular pyramid; a filling port is reserved between the first wide side (9) and the second wide side (10) on the inner layer sheet; this type of packaging bag has sufficient internal space and can better adapt to the irregular characteristics of Buddha's Hand slices;

[0053] (2) Measuring and bagging: Weigh the Buddha's Hand slices of the preset weight in a sterile operating room and fill them into the prepared packaging bag through the filling port by means of machinery or manual means; After filling, glue the first and second wide edges on the inner layer sheet together; After gluing, if there is extra space in the packaging bag, the gas can be discharged by squeezing so that the volume of the packaging bag is reduced.

[0054] (3) Making the outer packaging bag: Take a waterproof sheet material and cut it into a rectangle. Fold the two ends of the rectangular sheet material along the axis at 1 / 4 and 3 / 4 of the length of the long side to the same side. After folding, glue the two long sides of the sheet material together to make the outer packaging bag. The two long sides of the sheet material are sewn together to form the two wide sides of the outer packaging bag. The axis at 1 / 4 and 3 / 4 of the length of the long side is the two long sides of the outer packaging bag. Leave a filling opening between the two wide sides of the sheet material.

[0055] (4) Packaging: Insert the packaging bag containing Buddha's Hand tea slices into the outer packaging bag through the filling port, and then seal the filling port to obtain Buddha's Hand tea bag.

[0056] The Buddha's Hand tea bags disclosed in this embodiment were processed using the same batch of Buddha's Hand tea according to the processing method of Buddha's Hand tea specified in the "Hubei Province Traditional Chinese Medicine Processing Standard (2009 Edition)". The results of the comparison of the product usage are shown in Table 1.

[0057] Table 1. Comparison of Buddha's Hand Tea Bags and Buddha's Hand Herbal Pieces

[0058]

[0059] As can be seen from Table 1, the Buddha's Hand slices in the tea bags of this embodiment are relatively small in volume due to the cutting process. The length of the Buddha's Hand slices in the product is 1.2-1.5cm and the width is 0.6-1.2cm. However, the Buddha's Hand medicinal slices are relatively long and thin, so they occupy a large volume. When packaging, the length needs to be considered to determine the packaging. In the field of traditional Chinese medicine, special packaging paper is often used to package them before sale. The widest part of the packaging bag in this embodiment is 7.5cm. The existing medicine bags containing Buddha's Hand medicinal slices occupy significantly more space than the packaging bag in this embodiment.

[0060] The packaging bag in this embodiment has a maximum width of 7.5cm, which allows it to be placed in most cups sold on the market for brewing. It can be seen that the tea bags in this embodiment do not have special requirements for the tools used. Any cup that can hold water can be used for brewing, and the brewing process only takes 3-5 minutes. Buddha's Hand herbal medicine slices need to be decocted with water. At this time, a special decoction pot is required. During the entire decoction process, it is necessary to control not only the amount of water, but also the heat, stirring, and other factors. The decoction process needs to last for 30-40 minutes.

[0061] In this embodiment 1, the moisture content of the tea bags can be as low as 6%, while the moisture content of Buddha's Hand herbal slices is generally controlled below 15%. The lower the moisture content, the higher the content of active ingredients in the medicine, but the more susceptible the medicine is to moisture absorption. In this embodiment, because an outer packaging bag is used, there is no problem with moisture absorption, so the moisture content can be controlled within a lower range to further ensure efficacy.

[0062] In summary, when using the Buddha's Hand tea bag in this embodiment, simply tear open the outer packaging bag; then place the bag in a cup and pour in boiling water. Because of the added steps of perforation and cutting, the contact area between the herbs and water is significantly increased, thus accelerating the extraction of the active ingredients. Therefore, it can be drunk after steeping in boiling water for 3-5 minutes. After drinking, simply lift the used tea bag from the cup using the drawstring and leave it to decompose naturally in the environment.

[0063] Example 2

[0064] The total weight of the Buddha's Hand citron slices is 6g, the moisture content is 8%, the pore size is 0.5mm, and the pore density is 6 pores / cm³. 2 During drying, the perforated Buddha bag is dried with hot air at a temperature of 60°C until the preset moisture content is reached and then drying is stopped; the outer packaging bag is 13cm long, 10cm wide, and rectangular in shape. When making the outer packaging bag, the waterproof oil paper is folded and glued to obtain the outer packaging bag with a pre-filled opening; the length of the carrying rope is 5cm, and the rest is the same as in Example 1.

[0065] Example 3

[0066] The total weight of the Buddha's Hand citron slices is 4.5g, the moisture content is 7%, the pore size is 0.4mm, and the pore density is 7 pores / cm³. 2 During drying, the perforated Buddha bag is dried with hot air at a temperature of 65°C until the preset moisture content is reached and then drying is stopped; the outer packaging bag is 11.5cm long, 8.5cm wide, and rectangular in shape. When making the outer packaging bag, the waterproof pharmaceutical packaging plastic is folded and glued to obtain the outer packaging bag with a reserved opening; the length of the carrying rope is 6cm, and the rest is the same as in Example 1.

[0067] The embodiments 1-3 described above describe a Buddha's Hand tea bag in the traditional tea bag form, consisting of an inner bag and an outer bag; the inner bag is the packaging bag, and the outer bag is the outer packaging bag. To use this product, the outer packaging bag must first be torn open, then placed in a cup, and steeped in boiling water for 3-5 minutes like brewing tea before consumption. While tearing open the outer packaging bag is relatively inconvenient, the outer bag design provides good adhesion, making it less prone to breakage during transportation and extending its shelf life. In embodiments 1 and 2, the outer packaging bags are made of paper material. Compared to the pharmaceutical packaging plastic in embodiment 3, paper material is obviously more biodegradable, thus better aligning with the concept of green and environmentally friendly production and operation.

[0068] The packaging bags in Examples 1-3 above all adopt a triangular conical design, which provides more space for movement inside the bag and is more conducive to filling different dosages of Buddha's Hand slices. The outer packaging bag is made by folding the two ends of a rectangular sheet material along the axis at 1 / 4 and 3 / 4 of the length of the long side towards the same side; after folding, the two long sides of the sheet material are glued together. The filling opening of the outer packaging bag made by this method is on the center line of one side of the bag body. In industrial production, after the Buddha's Hand slices are filled, they can be glued from both sides towards the middle at the same time, which greatly increases the bonding speed.

[0069] Example 4

[0070] A type of Buddha's Hand tea bag includes a packaging bag and Buddha's Hand tea slices. The packaging bag is made by folding and gluing an inner thin sheet. The Buddha's Hand tea slices are filled inside the bag. The total weight of the Buddha's Hand tea slices is 3g. The length of each slice is 1.2-1.5cm and the width is 0.6-1.2cm. The water content of the Buddha's Hand tea slices is 6.5%. The inner thin sheet is rectangular, with a length of 15cm and a width of 6.6cm. Each Buddha's Hand tea slice has several perforated holes, which penetrate the entire slice. The diameter of each perforated hole is 0.3mm, and the density of perforations is 8 per cm. 2 .

[0071] The Buddha's Hand slices mentioned above are prepared by the following method:

[0072] (1) Buddha's Hand Purification: Take the raw medicinal material and remove impurities and moldy raw medicinal material by manual selection to obtain purified Buddha's Hand.

[0073] (2) Spray water to moisten: Place the cleaned Buddha's Hand in a bamboo tray and spray water mist onto the cleaned Buddha's Hand with a spraying device. After spraying water, wrap the bamboo tray with plastic sheet and let the cleaned Buddha's Hand moisten in the bamboo tray for 2-4 hours. Remove the plastic sheet when the humidity inside and outside the cleaned Buddha's Hand is consistent to obtain moistened Buddha's Hand.

[0074] (3) Drilling: Using mechanical drilling, water-permeable holes are made in the stale Buddha hand. The water-permeable holes are perpendicular to the outer skin of the Buddha hand and penetrate through the Buddha hand. After drilling, a perforated Buddha hand is obtained.

[0075] (4) Shredding: The perforated Buddha's Hand is cut into shreds of a preset width using a shredding machine to obtain perforated Buddha's Hand shreds;

[0076] (5) Cutting: The perforated Buddha's hand shreds are further cut into small segments of a preset length using a shredder to obtain perforated Buddha's hand shreds;

[0077] (6) Drying: Dry the perforated Buddha-shaped material with hot air at 68°C until the preset moisture content is reached, and then stop drying to obtain the dried Buddha-shaped material.

[0078] (7) Remove ash: Use air separation to remove the fine powder from the dried Buddha's Hand pieces to obtain Buddha's Hand slices.

[0079] The packaging bag is rectangular and made of filter paper. It also includes a moisture-proof layer, which consists of an outer sheet with the same shape as the inner sheet and a moisture-proof baffle. The outer sheet is sewn to both sides of the packaging bag, ensuring an opening at the same end. The moisture-proof baffle is a narrow strip cut from a waterproof sheet material, such as kraft paper. The two ends of the strip are inserted into two openings and are movably positioned between the outer and inner sheets. The moisture-proof baffle is 6.4 cm wide and 14.8 cm long, and has a pull-out ring at its center. This type of Buddha's Hand tea bag is manufactured using the following method:

[0080] (1) Packaging bag making: Take the inner layer sheet and fold both ends of the inner layer sheet along the axis at 1 / 4 and 3 / 4 of the long side to the same side of the inner layer sheet respectively; after folding, glue along the two long sides of the inner layer sheet to make the packaging bag; sew the two long sides of the inner layer sheet together to form the two long sides of the packaging bag; the axis at 1 / 4 and 3 / 4 of the long side is located on the two wide sides of the packaging bag; leave a filling port between the two wide sides of the inner layer sheet;

[0081] (2) Measuring and bagging: Weigh the Buddha's Hand slices of the preset weight in a sterile operating room and fill them into the prepared packaging bags through the filling port by means of machinery or manual means; after filling, glue the two wide edges on the inner layer of the thin slices together.

[0082] (3) Moisture-proof layer setting: Take the outer thin sheet, wrap the outer thin sheet and sew it to the packaging bag along the long side of the packaging bag. Leave an insertion port at one end of the two short sides of the outer thin sheet. There are two insertion ports, which are located on both sides of the packaging bag respectively. Fold the moisture-proof baffle along the center line of the length direction and attach a pull ring on the center line. Then insert the two ends of the moisture-proof baffle into the inner thin sheet and the outer thin sheet through the two insertion ports respectively to obtain Buddha's Hand tea bag.

[0083] Example 5

[0084] The packaging bag is rectangular and made of corn fiber. The total weight of the Buddha's Hand citron slices is 6g, the moisture content of the slices is 6.4%, the pore size is 0.4mm, and the pore density is 7 pores / cm³. 2 The moisture-proof baffle is a narrow strip cut from oil paper, with a width of 6.3cm and a length of 14.7cm. During drying, the perforated bag is dried with hot air at a temperature of 68°C until the preset moisture content is reached and then drying is stopped.

[0086] The packaging bag is rectangular and made of non-woven fabric. The total weight of the Buddha's Hand citron slices is 5g, the moisture content of the slices is 7.4%, the pore size is 0.5mm, and the pore density is 6 pores / cm³. 2 The moisture-proof baffle is a narrow strip cut from pharmaceutical packaging plastic. The width of the moisture-proof baffle is 6.35 cm and the length of the moisture-proof baffle is 14.75 cm. During drying, the perforated Buddha bag is dried with hot air at a temperature of 63°C until the preset moisture content is reached and then drying is stopped. The rest is the same as in Example 4.

[0087] To save production costs, the outer sheet and its corresponding inner sheet in the above embodiments 4-6 are made of the same material.

[0088] Examples 4-6 above disclose a Buddha's Hand tea bag with a moisture-proof layer on the packaging bag. When using this type of product, the user only needs to pull out the moisture-proof strip through the pull ring and brew it with boiling water like regular tea. It can be consumed after brewing for 3-5 minutes. Since it eliminates the need to tear open the outer bag, it is extremely convenient to use. At the same time, this type of tea bag also meets the requirements for moisture protection and mold prevention. In Examples 4 and 5, the moisture-proof strip is made of paper material. Compared to the pharmaceutical packaging plastic in Example 6, paper material is obviously easier to degrade, thus better conforming to the concept of green and environmentally friendly production and operation.
