Description

Technical Field

[0001] This invention relates to the field of scenting technology, specifically to an automatic scenting production line, scenting process, and control method. Background Technology

[0002] Jasmine tea, a type of scented tea, uses green tea as its base. The finished product, after the jasmine flowers are removed, is still considered a type of green tea and has a history of over 1000 years. The scenting process mainly involves the release of fragrance from the fresh jasmine flowers and the absorption of that fragrance by the tea leaves. The release of fragrance from fresh jasmine flowers is a biochemical process. Mature jasmine flowers, under the influence of enzymes, temperature, moisture, and oxygen, decompose to release fragrant substances. As the flowers open, they continuously release their aroma as the plant undergoes physiological changes.

[0003] The tea leaves absorb aroma through physical adsorption, and at the same time, they also absorb a large amount of water. Due to the osmosis of water, chemical adsorption occurs. Under the influence of heat and moisture, complex chemical changes take place, and the tea soup gradually changes from green to bright yellow. The taste changes from light and astringent to rich and mellow, forming the unique aroma, color, and flavor of flower tea.

[0004] Currently, the scenting process in jasmine tea production lines is fixed. Jasmine flowers and tea leaves are mixed via a feeding mechanism and then transported to a sealed scenting machine for the scenting process. After scenting, the jasmine flowers and tea leaves need to be separated by a tea-flower separator. However, this separation process is difficult to completely separate the jasmine flowers and tea leaves, resulting in foreign matter easily remaining in the jasmine tea, affecting its quality. Furthermore, the separation process also separates some tea leaves along with the jasmine flowers, causing some tea loss and reducing the yield. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] This invention provides an automated jasmine tea scenting production line, scenting process, and control method. The technical problem it solves is how to reduce foreign matter in jasmine tea and reduce tea loss.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] An automated scenting production line includes:

[0010] A scenting machine includes a housing and a first conveyor line and a second conveyor line located inside the housing. The second conveyor line is located below the first conveyor line. The scenting machine is equipped with an air circulation device, a condenser, an atomizer, an oxygen generator, and a temperature and humidity sensor. The atomizer is used to atomize the condensate from the condenser and discharge it into the housing. The oxygen generator is connected to the circulation pipe of the air circulation device.

[0011] A first feeding mechanism is configured to convey tea leaves or tea leaves and flower material to the first conveyor line;

[0012] The second feeding mechanism is configured to convey flower material or flower material and tea leaves to the second conveyor line;

[0013] A first discharge mechanism is connected to the first conveyor line;

[0014] The second discharge mechanism is connected to the second conveyor line;

[0015] The control device includes a control module electrically connected to the air circulation device, condenser, atomizer, oxygen generator, and temperature and humidity sensor.

[0016] In some embodiments, the first and second conveyor lines include at least two conveyor modules arranged parallel to each other and spaced apart. The end of the first feeding mechanism is located at the beginning of the uppermost conveyor module of the first conveyor line, and the end of the second feeding mechanism is located at the beginning of the uppermost conveyor module of the second conveyor line. Each conveyor module includes: two sets of drive wheels and driven wheels connected to the housing via a rotating shaft; a chain connecting the drive wheels and driven wheels in the same set, including a first conveying section above the drive wheels and driven wheels and a second conveying section below the drive wheels and driven wheels; and a conveyor plate rotatably connected to the two chains via a pin. The plate has through holes; and upper and lower support bars. The upper support bar is located below the first conveying section, and the lower support bar is located below the second conveying section. The upper and lower support bars have discharge ports. The horizontal distance between the discharge ports of the upper and lower support bars is greater than 2 / 3 of the length of the first or second conveying section. The support bars support the conveying plate, forming a conveying surface between the conveying plates in the first conveying section and between the conveying plates in the second conveying section. The conveying plate located at the discharge port loses the support of the support bars and rotates into the opening. The discharge port of the lower support bar of the first conveying line is offset from the discharge port of the second conveying line, and the discharge port of the lower support bar of the second conveying line is offset from the discharge port of the first conveying line.

[0017] In some implementations, the first and second feeding mechanisms include: a tea leaf elevator, a flower elevator, a camellia flower elevator, and a weighing and blending machine. The weighing and blending machine includes: a mounting frame; a blending cylinder rotatably connected to the mounting frame via a rotating shaft, the blending cylinder having an opening and a movable door on the opening, the movable door being slidably connected to the blending cylinder; and an opening and closing mechanism including an opening and closing motor connected to the blending cylinder, a gear connected to the opening and closing motor, and a rack cooperating with the gear and connected to the movable door. The rack is arranged along the sliding direction of the movable door; a weighing sensor is connected to the mounting frame; and a rotary drive mechanism is connected to the mounting frame and configured to drive the blending cylinder to rotate; wherein the blending cylinder is configured to receive tea leaves from the tea leaf elevator or flower material from the flower delivery elevator when the movable door is opened, or to pour tea leaves, flower material, or a mixture of tea leaves and flower material into the tea flower elevator, the scenting machine is provided with a feed inlet, and the end of the tea flower elevator is located directly above the feed inlet.

[0018] In some implementations, the assembly cylinder has arc-shaped grooves at both ends, the movable door is slidably disposed between the arc-shaped grooves, the rack is an arc-shaped rack and is fixed to the outside of the movable door; the assembly cylinder has a mounting frame, the two ends of the mounting frame are connected to the two ends of the assembly cylinder, and the opening and closing motor is fixed in the middle of the mounting frame.

[0019] In some implementations, the front end of the camellia elevator is equipped with a uniform feeder, and the camellia elevator and the scenting machine are equipped with a vision sensor. The vision sensor, the first feeding mechanism and the second feeding mechanism are electrically connected to the control module.

[0020] This invention also provides the following technical solution: a scenting process, applying the above-mentioned automatic scenting production line, comprising the following steps:

[0021] S1: Select the feeding method as needed. There are three feeding methods: Method 1: The first feeding mechanism conveys the tea leaves to the first conveyor line of the scenting machine, and the second feeding mechanism conveys the scenting material to the second conveyor line; Method 2: The first feeding mechanism conveys the mixture of tea leaves and scenting material to the first conveyor line and / or the second feeding mechanism conveys the mixture of tea leaves and scenting material to the second conveyor line; Method 3: The first feeding mechanism conveys the tea leaves to the first conveyor line and / or the second feeding mechanism conveys the tea leaves to the second conveyor line.

[0022] S2: Separate Scenting: When feeding method one is selected, the internal temperature of the scenting machine is 35-40℃ and the humidity is 85-90%RH. The scenting machine circulates air internally through an air circulation device. During the internal circulation process, some water is condensed into condensate through a condenser, and some condensate is evaporated by heating. Some condensate is introduced into an atomizing device, which atomizes the condensate and discharges the atomized water vapor into the pipe of the air circulation device for internal circulation again. During the internal circulation process, when the internal oxygen content is lower than the preset value, an oxygen generator supplies oxygen to the inside of the scenting machine. The scenting process is carried out for 10-15 hours under the above conditions.

[0023] S3: Contact-type scenting: The scenting machine scents the mixture of tea leaves and flower materials;

[0024] S4: Drying: The scenting machine dries the tea leaves;

[0025] S5: Discharge: After step S2, the first discharge mechanism discharges the tea leaves from the first conveyor line to the scenting machine, and the second discharge mechanism discharges the florets from the second conveyor line to the scenting machine; after step S3, the first discharge mechanism discharges the mixture of tea leaves and florets from the first conveyor line to the scenting machine and / or the second discharge mechanism discharges the mixture of tea leaves and florets from the second conveyor line to the scenting machine; after step S4, the first discharge mechanism discharges the tea leaves from the first conveyor line to the scenting machine and / or the second discharge mechanism discharges the tea leaves from the second conveyor line to the scenting machine.

[0026] Furthermore, when feeding method one is selected, the internal temperature of the scenting machine is 35-40℃, the humidity is 86-90RH, and the scenting time is 16-20 hours.

[0027] The present invention also provides the following technical solution: a control method for an automatic scenting production line, applied to the above-mentioned automatic scenting production line, comprising the following steps:

[0028] The control module sends corresponding control signals to the air circulation device, condenser, atomizer, or oxygen generator based on the temperature and humidity data collected by the temperature and humidity sensor. The air circulation device, condenser, atomizer, or oxygen generator then performs corresponding operations based on the control signals.

[0029] In some implementations, the temperature sensor is provided with a first temperature threshold T1, the humidity sensor is provided with a humidity threshold W, the oxygen content sensor is provided with an oxygen content threshold Q, and the control signal includes a first temperature adjustment signal, a humidification signal, and an oxygen generation signal.

[0030] When the temperature inside the casing is lower than the first temperature threshold T1, the gas circulation device switches to internal circulation mode.

[0031] The atomizer operates when the humidity inside the housing is lower than the humidity threshold W.

[0032] The oxygen generator operates when the oxygen content inside the casing is lower than the oxygen content threshold Q.

[0033] (III) Beneficial Effects

[0034] Compared with the prior art, the automatic scenting production line, scenting process and control method provided by the present invention have the following beneficial effects:

[0035] (1) When the automatic jasmine tea production line carries out the jasmine tea scenting process, the first feeding mechanism conveys the tea leaves to the first conveyor line of the jasmine tea scenting machine, and the second feeding mechanism conveys the jasmine flowers to the second conveyor line. In this way, the tea leaves and jasmine flowers do not come into contact with each other in the jasmine tea scenting machine. Then, the jasmine tea scenting machine controls the air circulation device, condenser, atomizer and oxygen generator to work through the control module to form the scenting environment and carry out the scenting. After the scenting is completed, the tea leaves are output from the first discharge mechanism and the jasmine flowers are output from the second discharge mechanism. In this way, the jasmine flowers and tea leaves do not need to be separated, which can effectively reduce foreign matter in jasmine tea, reduce tea loss and increase the yield.

[0036] (2) The automatic scenting production line can also carry out the scenting process of tea and flower material mixed together. That is, the first feeding mechanism sends the mixture of tea and flower material to the first conveyor line, and the second feeding mechanism sends the mixture of tea and flower material to the second conveyor line. The mixture is scented in the scenting machine. After the scenting is completed, it is output through the first feeding mechanism and the second feeding mechanism. Compared with the traditional scenting machine, it has two scenting routes, which can be selected as needed. When the two scenting routes are used at the same time, the scenting efficiency can be improved.

[0037] (3) The automatic scenting production line can also feed tea into the scenting machine through the first feeding mechanism and the second feeding mechanism, and dry the tea in the scenting machine.

[0038] (4) When the automatic scenting production line carries out the scenting process, the oxygen generator increases oxygen when the oxygen concentration is low, and the atomizer can atomize the condensed water with fragrance formed by the condenser and discharge the atomized fragrant water mist back into the scenting environment so that the tea can absorb the fragrance again. This process is repeated many times, which can effectively improve the aroma and oxygen content of jasmine tea. Attached Figure Description

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0053] The existing automatic jasmine scenting production line has the following problems: the applicable scenting process is limited; the separation process is difficult to completely separate jasmine flowers and tea leaves, and the resulting jasmine tea is prone to contain foreign matter, affecting the quality; at the same time, the separation process will separate some tea leaves along with jasmine flowers, resulting in some tea loss and reducing the yield.

[0054] To solve the above-mentioned technical problems, this embodiment provides an automatic scenting production line. Please refer to [link / reference]. Figures 1 to 4and Figure 9 As shown, Figure 1 This is a front view of the automated scenting production line in the embodiment. Figure 2 This is a top view of the automated scenting production line in the embodiment. Figure 3 This is a schematic diagram of the scenting machine in the embodiment. Figure 4 This is a schematic diagram of the first and second conveying routes in the embodiment. Figure 9 This is a logic flowchart of the control device in the embodiment.

[0055] An automatic scenting production line according to this embodiment includes: a scenting machine 1, a first feeding mechanism 2, a second feeding mechanism 3, a first discharging mechanism 4, a second discharging mechanism 5, and a control device 6.

[0056] The scenting machine 1 includes a housing 10 and a first conveyor line 11 and a second conveyor line 12 located inside the housing 10. The second conveyor line 12 is located below the first conveyor line 11. The scenting machine 1 is equipped with an air circulation device 13, a condenser 14, an atomizer 15, an oxygen generator 16, and a temperature and humidity sensor 17. The atomizer 15 is used to atomize the condensate water from the condenser 14 and discharge it into the housing 10. The oxygen generator 16 is connected to the circulation pipe of the air circulation device 13.

[0057] The aforementioned scenting machine 1 monitors the temperature and humidity of the scenting environment inside the casing 10 using a temperature and humidity sensor 17, circulates the airflow within the scenting environment using an air circulation device 13, condenses the scented fragrance into fragrant condensate using a condenser 14, atomizes the condensate using an atomizer 15 and discharges it back into the scenting environment, and uses an oxygen generator 16 to add oxygen to the scenting environment to increase the oxygen content; wherein, the casing 10 may be provided with a feed inlet leading to the first conveyor line 11 and the second conveyor line 12.

[0058] The first feeding mechanism 2 is configured to convey tea leaves or tea leaves and flower material to the first conveyor line 11; the second feeding mechanism 3 is configured to convey flower material or flower material and tea leaves to the second conveyor line 12.

[0059] The ends of the first feeding mechanism 2 and the second feeding mechanism 3 can be located directly above the inlet of the scenting machine 1, so that the tea leaves or flower material conveyed to the end can fall into the inlet by their own weight.

[0060] The first discharge mechanism 4 is connected to the first conveyor line 11, and the second discharge mechanism 5 is connected to the second conveyor line 12.

[0061] The first discharge mechanism 4 and the second discharge mechanism 5 are respectively used to output the tea leaves or flower materials from the first conveyor line 11 and the second conveyor line 12 to the outside of the scenting machine 1, and their heads can be located directly below the first conveyor line 11 or the second conveyor line 12.

[0062] The control device 6 includes a control module 60 electrically connected to the air circulation device 13, condenser 14, atomizer 15, oxygen generator 16 and temperature and humidity sensor 17. The control module 60 can also be electrically connected to the first feeding mechanism 2, the second feeding mechanism 3, the first discharging mechanism 4 and the second discharging mechanism 5.

[0063] The control device 6 can be integrated into the control box, which is fixed on the frame or the ground. The control module 60 can be a PLC control module 60.

[0064] In the automatic scenting production line of the above technical solution, during the scenting process, the first feeding mechanism 2 conveys the tea leaves to the first conveyor line 11 of the scenting machine 1, and the second feeding mechanism 3 conveys the scented materials to the second conveyor line 12. In this way, the tea leaves and scented materials do not come into contact within the scenting machine 1. Subsequently, the scenting machine 1 controls the air circulation device 13, condenser 14, atomizer 15, and oxygen generator 16 through the control module 60 to create a scenting environment for scenting. After the scenting is completed, the tea leaves are output from the first discharge mechanism 4, and the scented materials are output from the second discharge mechanism 5. In this way, the scented materials and tea leaves do not need to be separated, which can effectively reduce foreign matter in jasmine tea, reduce tea loss, and increase the yield. Meanwhile, this automatic scenting production line can also perform a mixed scenting process of tea leaves and florets. Specifically, the first feeding mechanism 2 delivers the mixture of tea leaves and florets to the first conveyor line 11, and the second feeding mechanism 3 delivers the mixture to the second conveyor line 12. The mixture undergoes scenting within the scenting machine 1. After scenting, it is output through the first feeding mechanism 2 and the second feeding mechanism 3. Compared to a traditional scenting machine 1, this has two scenting routes that can be selected as needed. When both scenting routes are used simultaneously, the scenting efficiency is improved. Last but not least, this automatic scenting production line can also feed tea leaves into the scenting machine 1 through the first feeding mechanism 2 and the second feeding mechanism 3, and dry the tea leaves within the scenting machine 1. It can be seen that the above-described automatic scenting production line can perform separate scenting, contact scenting, and tea drying as needed, offering diverse functions and strong applicability.

[0065] See Figure 5 and Figure 6 As shown, Figure 5 This is a front view of the conveying module in the embodiment. Figure 6This is a top view of the conveying module in the embodiment. In one embodiment of the first conveying line 11 and the second conveying line 12 described above, the first conveying line 11 and the second conveying line 12 include at least two conveying modules 100. The conveying modules 100 are arranged vertically parallel and spaced apart, forming a layered arrangement. The end of the first feeding mechanism 2 is located at the beginning of the uppermost conveying module 100 of the first conveying line 11, and the end of the second feeding mechanism 3 is located at the beginning of the uppermost conveying module 100 of the second conveying line 12. The conveying module 100 includes: a power wheel 1 01. Driven wheel 102, chain 103, conveyor plate 104, upper support bar 105, and lower support bar 106. Two sets of drive wheels 101 and driven wheels 102 are provided, which are respectively connected to the housing 10 via rotating shafts. The chain 103 connects the drive wheels 101 and driven wheels 102 in the same set, and is in a ring shape with two chains. The chain 103 includes a first conveying section 111 located above the drive wheels 101 and driven wheels 102 and a second conveying section located below the drive wheels 101 and driven wheels 102. 112; The conveyor plate 104 is rotatably connected between two chains 103 via a pin. The conveyor plate 104 is provided with a through hole 113 for airflow. The upper support bar 105 is located below the first conveyor section 111, and the lower support bar 106 is located below the second conveyor section 112. The upper support bar 105 and the lower support bar 106 are provided with discharge ports 114. The horizontal distance between the discharge ports 114 of the upper support bar 105 and the lower support bar 106 is greater than 2 / 3 of the length of the first conveyor section 111 or the second conveyor section 112. The conveying surface is formed between the conveying plates 104 in the first conveying section 111 and between the conveying plates 104 in the second conveying section 112. The conveying surface can continuously convey materials. The conveying plate 104 located at the discharge port 114 loses the support of the support bar and rotates into the opening. The opening of the lower support bar 106 of the first conveying line 11 is offset from that of the second conveying line 12, and the opening of the lower support bar 106 of the second conveying line 12 is offset from that of the first conveying line 11. In this embodiment, the tea leaves first enter the uppermost conveying module 100 of the first conveying line 11. The tea leaves pass through the conveying surface between the first conveying sections 111 and fall from the opening of the upper support bar 105 into the conveying surface between the second conveying sections 112. Then, they fall from the opening of the lower support bar 106 into the lower conveying module 100. The overall conveying path is multi-segment S-shaped, which can effectively extend the conveying path of the tea leaves inside the scenting machine 1. Compared with traditional conveyor belts, the first conveying line 11 and the second conveying line 12 can simultaneously convey a larger quantity of tea leaves and flower materials within the gear space, thereby increasing the capacity and processing capacity of the scenting machine 1 per unit time.

[0066] See Figure 7 and Figure 8 As shown, Figure 7 This is a perspective view of the first feeding mechanism in the embodiment. Figure 8This is a perspective view of the weighing and blending machine in one embodiment. In one embodiment of the first feeding mechanism 2 and the second feeding mechanism 3, the first feeding mechanism 2 and the second feeding mechanism 3 include: a tea leaf elevator 21, a flower feeding elevator 22, a camellia flower elevator 23, and a weighing and blending machine 24. The weighing and blending machine 24 includes: a mounting frame 241, a blending cylinder 242, an opening and closing mechanism 243, a weighing sensor 244, and a rotary drive mechanism 245. The blending cylinder 242 is rotatably connected to the mounting frame 241 via a rotating shaft. The blending cylinder 242 has an opening, and a movable door 246 is provided on the opening. The movable door 246 is slidably connected to the blending cylinder 242. The opening and closing mechanism 243 includes an opening and closing motor 2431 connected to the blending cylinder 242, a gear 2432 connected to the opening and closing motor 2431, and a rack 2433 that cooperates with the gear 2432 and is connected to the movable door 246. A rack 2433 is arranged along the sliding direction of the movable door 246; a weighing sensor 244 is connected to a mounting bracket 241 and can be mounted on a frame; a rotary drive mechanism 245 is connected to the mounting bracket 241 and is configured to drive the blending cylinder 242 to rotate. The rotary drive mechanism 245 can drive the rotating shaft to rotate through a transmission mechanism, thereby driving the blending cylinder 242 to rotate; wherein, the blending cylinder 242 is configured to receive tea leaves from the tea leaf elevator 21 or flower material from the flower delivery elevator 22 when the movable door 246 is opened, or to pour tea leaves, flower material, or a mixture of tea leaves and flower material into the tea flower elevator 23. The scenting machine 1 is provided with a feed inlet, and the end of the tea flower elevator 23 is located directly above the feed inlet; wherein, a conveyor belt can also be provided to transfer the raw materials from the flower delivery elevator 22 or the tea leaf elevator 21 to the blending cylinder 242. In this embodiment, the tea leaf elevator 21 lifts the tea leaves above the opening of the blending cylinder 242, and the flower delivery elevator 22 lifts the flower material above the opening of the blending cylinder 242. The blending cylinder 242 is opened by the opening and closing motor 2431, which drives the movable door 246 to open, allowing the flower material and tea leaves to fall into the blending cylinder 242. The weighing sensor 244 weighs the flower material and tea leaves. Once the preset weight ratio is reached, the movable door 246 closes, and the rotation drive mechanism 245 drives the blending cylinder 242 to rotate, mixing the flower material and tea leaves. Then, open the movable door 246 and pour the tea leaves, flower materials, or mixed materials into the tea flower elevator 23. The tea flower elevator 23 then sends the above materials into the scenting machine 1. With this setup, compared to the existing scenting production line, this automatic scenting production line uses the flower feeding elevator 22 and the tea leaf elevator 21 to weigh the flower materials and tea leaves. The weighing and blending machine 24 can weigh the tea leaves and flower materials, so that the tea leaves and flower materials are accurately blended according to the preset weight ratio. It can also rotate and mix the blended materials, eliminating the need for mixing equipment.

[0067] In one embodiment where the movable door 246 is slidably connected to the assembly cylinder 242, the assembly cylinder 242 is provided with arc-shaped sliding grooves 2420 at both ends, and the movable door 246 is slidably disposed between the arc-shaped sliding grooves 2420. The rack 2433 is an arc-shaped rack 2433 and is fixed to the outside of the movable door 246. The assembly cylinder 242 is provided with a mounting frame 241, and the two ends of the mounting frame 241 are connected to the two ends of the assembly cylinder 242. The opening and closing motor 2431 is fixed in the middle of the mounting frame 241. The opening and closing motor 2431 drives the gear 2432 to rotate with the mounting frame 241 as support. The gear 2432 drives the arc-shaped rack 2433 to rotate around the rotating axis, thereby driving the movable door 246 to slide in the arc-shaped sliding groove 2420, realizing the opening and closing, and improving the stability of the sliding of the movable door 246.

[0068] See Figure 7 As shown, in this embodiment, a uniform feeder 231 is provided at the front end of the tea flower elevator 23. A vision sensor 25 is provided on the tea flower elevator and the scenting machine. The vision sensor 25, the first feeding mechanism 2, and the second feeding mechanism 3 are electrically connected to the control module 60. With this configuration, the uniform feeder 231 can make the thickness of the raw material uniform by sweeping the top of the raw material. The vision sensor 25 on the tea flower elevator 23 is used to monitor the condition of the raw material before it enters the scenting machine 1. When there are impurities in the raw material or the mixing is not uniform in some areas, the image information is fed back to the control module 60. The control module 60 sends a control command to the first feeding mechanism 2 or the second feeding mechanism 3 according to the image information to stop it. Thus, the factors that cause the pause can be eliminated before the raw material enters the scenting machine 1. The vision sensor 25 inside the scenting machine 1 can monitor the tea scenting process.

[0069] This invention also provides the following technical solution: a scenting process, applying the above-mentioned automatic scenting production line, comprising the following steps:

[0070] S1: Select the feeding method as needed. There are three feeding methods: Method 1: The first feeding mechanism 2 feeds the tea leaves to the first conveyor line 11 of the scenting machine 1, and the second feeding mechanism 3 feeds the scenting material to the second conveyor line 12; Method 2: The first feeding mechanism 2 feeds the mixture of tea leaves and scenting material to the first conveyor line 11 and / or the second feeding mechanism 3 feeds the mixture of tea leaves and scenting material to the second conveyor line 12; Method 3: The first feeding mechanism 2 feeds the tea leaves to the first conveyor line 11 and / or the second feeding mechanism 3 feeds the tea leaves to the second conveyor line 12.

[0071] S2: Separate Scenting: When feeding method one is selected, the internal temperature of scenting machine 1 is 35-40℃ and the humidity is 85-90RH. Scenting machine 1 circulates air internally through air circulation device 13. The condenser 14 condenses some of the water during the internal circulation process into condensate water, and evaporates some of the condensate water by heating. Some of the condensate water is introduced into the atomizing device, which atomizes the condensate water and discharges the atomized water vapor into the pipe of air circulation device 13 for internal circulation again. During the internal circulation process, when the internal oxygen content is lower than the preset value, oxygen generator 16 supplies oxygen to the inside of scenting machine 1. Scenting is carried out for 10-15 hours under the above conditions.

[0073] S4: Drying: The scenting machine 1 dries the tea leaves;

[0074] S5: Discharge: After step S2, the first discharge mechanism 4 discharges the tea leaves from the first conveyor line 11 into the scenting machine 1, and the second discharge mechanism 5 discharges the florets from the second conveyor line 12 into the scenting machine 1; after step S3, the first discharge mechanism 4 discharges the mixture of tea leaves and florets from the first conveyor line 11 into the scenting machine 1 and / or the second discharge mechanism 5 discharges the mixture of tea leaves and florets from the second conveyor line 12 into the scenting machine 1; after step S4, the first discharge mechanism 4 discharges the tea leaves from the first conveyor line 11 into the scenting machine 1 and / or the second discharge mechanism 5 discharges the tea leaves from the second conveyor line 12 into the scenting machine 1.

[0075] The present invention also provides the following technical solution: a control method for an automatic scenting production line, applied to the above-mentioned automatic scenting production line, comprising the following steps:

[0076] The control module 60 sends corresponding control signals to the air circulation device 13, condenser 14, atomizer 15 or oxygen generator 16 based on the temperature and humidity data collected by the temperature and humidity sensor 17. The air circulation device 13, condenser 14, atomizer 15 or oxygen generator 16 then perform corresponding operations according to the control signals.

[0077] In some implementations, a first temperature threshold T1 is set in the temperature sensor, a humidity threshold W is set in the humidity sensor, and an oxygen content threshold Q is set in the oxygen content sensor. The control signals include a first temperature adjustment signal, a humidification signal, and an oxygen generation signal.

[0078] When the temperature inside the casing is lower than the first temperature threshold T1, the gas circulation device switches to internal circulation mode.

[0079] When the humidity inside the housing is lower than the humidity threshold W, the atomizer 15 will operate.

[0080] When the oxygen content inside the casing is lower than the oxygen content threshold Q, the oxygen generator 16 operates.

[0081] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
