Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of tea preparation, and in particular relates to a primary processing production line and a production process for Duyun Maojian tea. Background Art
[0002] Duyun Maojian tea has a long history. Its origin is on Yunwu Mountain, which is located at the junction of Duyun City and Guiting County in Guizhou Province. As early as the Ming Dynasty, the "fishhook tea" and "sparrow tongue tea" produced in Duyun were listed as tribute to the court. Duyun Maojian tea is famous for its thin, round, shiny, straight, white hair, emerald green color, high and lasting fragrance after brewing, rich taste, sweet aftertaste, and bright and clear soup color. The color of its dry tea is green with yellow, the soup color is green with yellow, and the bottom of the leaves is green with yellow, which has the characteristics of "three greens and yellow". The existing production of Duyun Maojian tea is often prepared purely by hand, or a combination of partly manual and partly mechanical tea-making equipment. The purely manual preparation method is inefficient and difficult to meet the needs of large-scale production. Manual operation is not only time-consuming and labor-intensive, but also requires extremely high technical skills from tea-making masters, making it difficult to ensure the quality stability of each batch of tea. Secondly, during the manual tea-making process, due to the interference of human factors, the tea is easily damp, deteriorated or contaminated, thus affecting the quality and safety of the tea. Although the combination of partly manual and partly mechanical tea-making equipment has improved production efficiency to a certain extent, there are still some problems. First, the connection between mechanical equipment and manual operation is not tight enough, which can easily lead to a bottleneck effect on the production line and affect the overall production efficiency. Summary of the invention
[0003] The purpose of the present invention is to provide a Duyun Maojian tea primary processing production line and production process in response to the above-mentioned technical problems. Compared with pure manual tea making and semi-manual and semi-mechanical tea making, it avoids interference from human factors and the loose connection between mechanical equipment and manual operation, which easily leads to a bottleneck effect on the production line and affects the overall production efficiency.
[0004] In view of this, the present invention provides a Duyun Maojian tea primary processing production line, including a screening module, a withering module, a rolling module, a shaping module and a flavoring module. The modules are sequentially connected by a conveying device, and the conveying device can transfer the tea leaves that have completed the processing in the module to the next module.
[0005] In the present technical scheme, the conveying device is a flat conveyor or an inclined conveyor, which sequentially conveys and connects each module in the production line; the screening module is a tea sorting machine, which puts tea leaves of the same or adjacent batches picked at the same time into the tea sorting machine for classification and screening according to the size and tenderness of the tea leaves; tea leaves with higher tenderness usually have better taste and aroma. For example, the raw tea leaves of the special grade Maojian are uniform and full of single teeth, while the raw tea leaves of the first grade Maojian are one tooth head and one leaf, and the raw tea leaves of the second grade Maojian include one tooth head and one or two leaves; the rolling module is selected as a tea rolling machine, and during the rolling process, the cell walls of the tea leaves are broken, causing the tea juice to overflow and adhere to the surface of the tea leaves, laying the foundation for subsequent shaping, aroma enhancement and other processes, and also promoting the transformation of chemical components in the tea leaves, such as the oxidation and polymerization of polyphenols, which helps to improve the quality and taste of the tea leaves. It can also play a preliminary plastic role. The shaping module can adopt a series-arranged tea-hair-raising machine, a shaping machine or a strip conditioning machine to play the role of showing the tea-hair and shaping. Showing the tea-hair makes the white hair (fine white fluff) on the surface of the tea more visible and more prominent, making the tea look more tender and high-end, which is especially important for famous teas such as Duyun Maojian. The main function of shaping is to shape the appearance of the tea to meet specific standards or consumers' aesthetic needs. The aroma-enhancing module is a drying and aroma-enhancing machine, which further dries the tea leaves through high-temperature baking, while stimulating the aroma of the tea leaves, improving the quality and taste of the tea leaves, and finally cooling the tea. Compared with pure manual tea making and semi-manual and semi-mechanical tea making, the present invention avoids interference from human factors and avoids the lack of close connection between mechanical equipment and manual operation, which can easily lead to a bottleneck effect on the production line and affect the overall production efficiency.
[0006] In the above technical solution, further, the kneading module includes a primary kneading machine and a secondary kneading machine arranged in series, the feeding end of the primary kneading machine is connected to the killing module through a conveying device, and the discharging end of the secondary kneading machine is connected to the shaping module through a conveying device.
[0007] In the above technical solution, further, a dehydration module is provided between the primary kneading machine and the secondary kneading machine.
[0008] In the present technical scheme, both the primary kneading machine and the secondary kneading machine are tea rolling machines, and the rolling is divided into two steps, primary kneading and secondary kneading, and a dehydration module is arranged in between. The dehydration module is a drying equipment, and the temperature is set to 80-120°C. This temperature range can effectively remove excess moisture in the tea leaves, while avoiding excessively high temperatures that lead to a decrease in the quality of the tea leaves. The tea leaves can be processed step by step in the order of primary kneading, dehydration, and secondary kneading. Each step lays the foundation for the next step. This step-by-step processing method helps the tea leaves to better absorb moisture and heat and undergo sufficient chemical reactions, thereby maximizing the quality and taste of the tea leaves.
[0009] In the above technical scheme, further, the shaping module includes a hair-displaying module and a shaping module which are connected in sequence in the transmission direction of the conveying device, the hair-displaying module and the re-kneading machine are connected through the conveying device, the hair-displaying module and the shaping module are connected through the conveying device, and the shaping module and the fragrance-enhancing module are connected through the conveying device.
[0010] In the present technical scheme, the shaping module can adopt a series-arranged tea leaf lifting machine, shaping machine or strip conditioning machine to play the role of showing the tea leaf hairs and shaping. Showing the tea leaf hairs makes the white hairs (fine white hairs) on the surface of the tea leaves more visible, and the white hairs on the surface of the tea leaves are more prominent, making the tea leaves look fresher and more upscale, which is especially important for famous and high-quality teas such as Duyun Maojian. The main function of shaping is to shape the appearance of the tea leaves so that they meet specific standards or the aesthetic needs of consumers.
[0011] In the above technical scheme, further, a humidity control module is arranged behind the withering module, the dehydration module and the tea leaf revealing module. The humidity control module comprises a cooling module and a rehumidification module which are arranged in sequence. The tea leaves passing through the humidity control module are cooled and humidified in sequence.
[0012] In this technical solution, the cooling module can be a fan, air conditioner, etc., which is used to quickly reduce the temperature of tea leaves during large-scale production. It should be noted that mechanical cooling should avoid blowing directly onto the tea leaves to avoid excessive evaporation of moisture on the surface of the tea leaves. Natural cooling can also be used to spread the tea leaves after withering in a clean bamboo dustpan or a large bamboo dustpan, and use natural wind or indoor ventilation conditions for cooling. During the cooling process, it should be ensured that the temperature of the tea leaves drops rapidly to room temperature or slightly above room temperature (about 20℃-25℃); the rehumidification module uses a humidifier to spray an appropriate amount of water mist on the surface of the tea leaves to increase the humidity of the tea leaves. The humidity and spray volume of the humidifier should be adjusted according to the actual situation of the tea leaves. During the rehumidification process, the indoor temperature should be kept stable between 20℃-25℃, and the relative humidity on the surface of the tea leaves should be controlled at about 65%-75% by a humidifier or natural rehumidification method. The moisture adjustment module adjusts the moisture content to facilitate the processing of the next module.
[0013] In the above technical scheme, further, it also includes a screening device. There are several screening devices, which are connected and arranged in the production line. They are respectively arranged between the withering module, the rolling module and the shaping module, and after the aroma module. The screening device can effectively remove tea stems and fragments generated in the tea processing.
[0014] In the present technical solution, the screening device can be a linear conveying vibrating screen. The tea leaves are moved from the surface of the screen under the operation of the vibrating motor, and the tea stems and fragments fall from the mesh of the screen. There are multiple devices, which are respectively arranged in several modules to remove the tea stems and fragments in time to avoid the tea stems and fragments produced by the previous module being brought into the next module for invalid processing, which may even affect the processing of the complete tea leaves.
[0015] In the above technical solution, further, a sample analysis device is included. The sample sampling device includes a mechanical arm for sampling each module and a detection device. The detection device detects the samples sampled by the mechanical arm.
[0016] In the present technical solution, the detection device of each module may not be a single detection device, but may be a detection device for detecting a certain data required for tea. By sampling and retaining tea in each link of each module, the quality changes of tea during the processing process can be monitored in real time to ensure the stable quality of each batch of tea. Once a quality problem of tea is found, it can be quickly traced back to the specific production link through the sample analysis device, and timely measures can be taken to adjust and improve it.
[0017] In the above technical scheme, further, the production process of the above Duyun Maojian tea primary processing production line is also included, comprising the following steps:
[0018] Step 1: Screening: Classify and screen the tea leaves according to leaf size, tenderness, and picking time;
[0019] Step 2: De-greening: the tea leaves of the same batch after the above grading and screening are put into the drum de-greening machine through the conveying device for de-greening. The temperature of the drum de-greening machine is set between 120 and 130 degrees Celsius.
[0020] Step 3: Cooling and rehumidification. The tea leaves that have been withered are cooled in a cooling module. A mechanical cooling room is used to avoid blowing the tea leaves directly. The cooled tea leaves are then sent to the rehumidification module for water replenishment.
[0021] Step 4: rolling, the tea leaves are rolled first and then rolled again, with a humidity control module provided between the first and second rolling. The first rolling destroys part of the cell walls of the tea leaves through rolling to allow the tea juice to leach out, and the second rolling further rolls the tea leaves into shape, making the tea leaves more compact.
[0022] Step 5: shaping, the tea leaves that have been rolled are sequentially exposed and shaped. A humidity control module is provided between the exposure and shaping. The humidity control module adjusts and balances the moisture of the tea leaves. The exposure can make the fine hairs (i.e. white hairs) on the surface of the tea leaves stand up, increasing the silvery white luster of the tea leaves. Through the shaping process, the tea leaves can be shaped into specific strips. The humidity control module between the exposure module and the shaping module adjusts the moisture and provides a buffer period.
[0023] Step 6: Drying and aroma enhancement. Finally, the tea leaves are transported into the aroma enhancement machine for drying and aroma enhancement. The temperature of the aroma enhancement machine is set between 80 and 120°C.
[0024] In the above technical solution, further, steps one to ten are each provided with a sampling and analysis step, for sampling and retention, and data analysis of the samples.
[0025] In the above technical solution, further, during the rehumidification process in step three, the temperature is maintained at 20-25° C., and the relative humidity on the surface of the tea leaves is controlled between 65% and 75% by the rehumidification module.
[0026] The beneficial effects of the present invention are:
[0027] 1 Compared with pure manual tea making and semi-manual and semi-mechanical tea making, the present invention avoids interference from human factors and the lack of tight connection between mechanical equipment and manual operation, which easily leads to a bottleneck effect on the production line and affects the overall production efficiency;
[0028] 2. Both the primary kneading machine and the secondary kneading machine are tea rolling machines. The rolling is divided into two steps: primary kneading and secondary kneading. A dehydration module is set in between. The dehydration module is a drying device with a temperature set to 80-120°C. This temperature range can effectively remove excess moisture from the tea leaves while avoiding excessively high temperatures that may lead to a decrease in the quality of the tea leaves. The tea leaves can be processed step by step in the order of primary kneading, dehydration, and secondary kneading. Each step lays the foundation for the next step. This step-by-step processing method helps the tea leaves absorb moisture and heat better and undergo sufficient chemical reactions, thereby maximizing the quality and taste of the tea leaves.
[0029] 3. There are several screening devices, which are connected and arranged in the production line, respectively arranged between the withering module, the rolling module and the shaping module, and after the aroma module. The screening device can effectively remove the tea stems and fragments generated in the tea processing. The screening device can be a linear conveying vibrating screen. The tea leaves move from the surface of the screen under the operation of the vibration motor, and the tea stems and fragments fall from the mesh of the screen. There are multiple screening devices, which are respectively arranged in several modules to remove the tea stems and fragments in time to avoid the tea stems and fragments generated by the previous module being brought into the next module for invalid processing, which may even affect the processing of the complete tea leaves.

The screening module (not shown) is a tea sorting machine, which puts tea leaves of the same or adjacent batches picked at the time into the tea sorting machine and grades and screens the tea leaves according to the size and tenderness of the tea leaves. Tea leaves with higher tenderness usually have better taste and aroma. For example, the raw tea leaves of special-grade Maojian are uniform and full of single teeth, while the raw tea leaves of first-grade Maojian are one tooth and one leaf, and the raw tea leaves of second-grade Maojian include one tooth and one or two leaves; the rolling module 2 is selected as a tea rolling machine. During the rolling process, the cell walls of the tea leaves are broken, which causes the tea juice to overflow and adhere to the surface of the tea leaves, laying the foundation for subsequent shaping, aroma enhancement and other processes, and also promoting the transformation of chemical components in the tea leaves, such as the oxidation and polymerization of polyphenols, which helps to improve the quality and taste of the tea leaves, and can also It plays a preliminary plastic role. The shaping module 3 can adopt a series-arranged hair-raising machine, a shaping machine or a conditioning machine to play the role of showing the hair and shaping. Showing the hair is to make the white hair (fine white fluff) on the surface of the tea more visible, and the white hair on the surface of the tea is more prominent, making the tea look more tender and high-end, which is especially important for famous teas such as Duyun Maojian. The main function of shaping is to shape the appearance of the tea to meet specific standards or consumers' aesthetic needs. The aroma-enhancing module 4 is a drying and aroma-enhancing machine, which further dries the tea by high-temperature baking, while stimulating the aroma of the tea, improving the quality and taste of the tea, and finally cooling the tea. Compared with pure manual tea making and semi-manual and semi-mechanical tea making, the present invention avoids interference from human factors and avoids the lack of close connection between mechanical equipment and manual operation, which is easy to cause a bottleneck effect on the production line and thus affect the overall production efficiency.
[0042] The kneading module 2 includes a primary kneading machine 21 and a secondary kneading machine 22 arranged in series, the feed end of the primary kneading machine 21 is connected to the fixing module 1 through a conveying device, and the discharge end of the secondary kneading machine 22 is connected to the shaping module 3 through a conveying device.

This temperature range can effectively remove excess moisture in the tea leaves, while avoiding the degradation of the quality of the tea leaves due to excessively high temperatures. The tea leaves can be processed step by step in the order of primary kneading, dehydration, and secondary kneading. Each step lays the foundation for the next step.

During the cooling process, it should be ensured that the temperature of the tea leaves drops rapidly to room temperature or slightly above room temperature (about 20°C-25°C); the rehumidification module 52 uses a humidifier to spray an appropriate amount of water mist on the surface of the tea leaves to increase the humidity of the tea leaves. The humidity and spray amount of the humidifier should be adjusted according to the actual situation of the tea leaves. During the rehumidification process, the indoor temperature should be kept stable between 20°C-25°C, and the relative humidity on the surface of the tea leaves should be controlled at about 65%-75% by a humidifier or natural rehumidification method.

8. The Duyun Maojian tea primary processing production line according to claim 1, characterized in that: The production process of the above-mentioned Duyun Maojian tea primary processing production line also includes the following steps: Step 1: Screening: Classify and screen the tea leaves according to leaf size, tenderness, and picking time; Step 2: Fixing the tea leaves. The tea leaves of the same batch after the above grading and screening are put into a drum fixing machine through a conveying device for fixing. The temperature of the drum fixing machine is set between 120 and 130°C. Step 3: Cooling and rehumidification: the tea leaves that have been finished withering are cooled in a cooling module (51) using a mechanical cooling chamber to avoid blowing the tea leaves directly, and then the cooled tea leaves are sent to a rehumidification module (52) to replenish moisture; Step 4: rolling, the tea leaves are subjected to primary rolling and secondary rolling in sequence, a humidity control module (5) is provided between the primary rolling and secondary rolling, the primary rolling destroys part of the cell walls of the tea leaves by rolling to allow the tea juice to leach out, and the secondary rolling further rolls the tea leaves into shape, making the tea leaves more compact; Step 5: shaping, the tea leaves after rolling are sequentially exposed to the hairs and shaped, a humidity control module (5) is provided between the exposure to the hairs and the shaping, the humidity control module (5) adjusts and balances the moisture of the tea leaves, the exposure to the hairs can make the fine hairs (i.e. white hairs) on the surface of the tea leaves stand upright, increasing the silvery white luster of the tea leaves, and through the shaping process, the tea leaves can be molded into a specific strip shape, the humidity control module (5) between the exposure to the hairs module (31) and the shaping module (32) adjusts the moisture and provides a buffer period; Step 6: Drying and aroma enhancement. Finally, the tea leaves are transported into the aroma enhancement machine for drying and aroma enhancement. The temperature of the aroma enhancement machine is set between 80 and 120°C.
