DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] As attached Figure 1 With attached Fig.16 The jasmine tea processing equipment shown includes a frame 1, which is two rectangular plates with the same length and width. The jasmine tea gradually falls from the top of the frame 1, and four sets of processes are successively implemented: spreading the flowers to dry, scenting and splicing the flowers, screening and removing the flowers, and re-firing the scented tea.

[0055] The requirement for picking jasmine flowers is to pick the buds that are about to bloom at noon. The internal temperature of the picked buds is relatively high during transportation and pressing, or if they contain rain water when picked, they need to be spread out and dried quickly.

[0056] like Figure 2 As shown, two drying boards 2 are rotatably installed between the frames 1 via a rotating shaft. The cross section of the drying board 2 is a polygonal structure composed of three groups of plates, and half of the drying board 2 along the length direction is a sieve structure for screening the green buds and impurities of jasmine flowers.

[0057] The width of the bottom plate of the airing board 2 can overlap. In order to ensure that they can be parallel after overlapping, one set of the airing boards 2 is provided with a bending portion. Figure 2 The state shown is the initial state of the drying board 2), pour the picked jasmine tea onto the drying board 2 from one end, then spread the jasmine flowers evenly, and cool them in time to avoid the temperature of the flower pile being too high. When the temperature is too high, or when the flowers are picked in rain, they need to be spread thinly, blown with air, and the moisture on the surface of the flowers evaporated. After the surface water is dry, they can be piled up for maintenance.

[0058] In order to allow the flower pile to be blown, an air duct 5 is installed on the top of the rack 1 through a rod. The rod is installed on the top of the rack 1, and the air duct 5 is installed on the top of the rod. A number of air outlets are opened at equal intervals at the bottom of the air duct 5, and one end of the air duct 5 is connected to an external fan. When necessary, air is blown to the flower pile through the air duct 5.

[0059] like Figure 7 , Figure 8 As shown, in the present device, a retreat groove 101 is provided on one side of the frame 1, and connecting plates 403 are rotatably installed on the sides of the retreat groove 101 and the frame 1, and an I-beam 4 and a screw rod 401 are installed between the two connecting plates 403, and an L-shaped plate 407 is provided on the side of one of the connecting plates 403, one end of the screw rod 401 is rotatably connected to the L-shaped plate 407, and a motor is installed on the side of the corresponding connecting plate 403, and the output shaft of the motor is connected to one end of the screw rod 401 for driving the screw rod 401 to rotate.

[0060] A motor is also installed on the side of the retreat groove 101 and the frame 1, and the motor is used to drive the connecting plate 403.

[0061] The cross section of the I-beam 4 is arranged to be an “I”-shaped structure, and rack surfaces 404 are provided in the through grooves on both sides of the I-beam 4 .

[0062] A connecting piece 406 is sleeved on the screw rod 401 and the I-beam 4, one end of which is threadedly connected to the screw rod 401, and the other end is slidably connected to the I-beam 4, that is, the I-beam 4 passes through the connecting piece 406. During operation, the screw rod 401 rotates forwards and backwards, and can drive the connecting piece 406 to reciprocate on the I-beam 4. Shaft rods 402 are arranged on both sides of the connecting piece 406, one end of the shaft rod 402 rotates through the connecting piece 406, and a gear three 405 meshing with the rack surface 404 is arranged at the end, the rack surface 404 is a rack structure arranged in the through groove of the I-beam 4, and a distribution blade is arranged at the other end of the shaft rod 402. In this device, a plurality of distribution blades are arranged at equal angles along the circumferential surface of the shaft rod 402.

[0063] After the jasmine flowers are picked, they are poured into the drying board 2. The motor first drives the connecting plate 403 to rotate, so that the entire distribution blade rotates to the bottom. In this state, the motor drives the screw rod 401 to rotate, and synchronously drives the connecting piece 406 to move. At the same time, since the gear three 405 is engaged with the rack surface 404, when the connecting piece 406 moves, it will also drive the shaft 402 and the distribution blades on the shaft 402 to rotate, so that the piled jasmine flowers can be evenly distributed. To ensure that the jasmine flowers can be evenly distributed, the connecting piece 406 can be moved back and forth multiple times during work to spread the jasmine flowers to about 10 cm.

[0064] After the tiling is completed, the motor drives the connecting plate 403 to rotate again, rotates the shaft 402 and the distribution blades upward, and retreats to the top of the retreat groove 101 to avoid affecting the rotation of the drying plate 2.

[0065] like Figures 1 to 9 As shown, during the transportation process, flowers generate heat due to pressure and respiration. In order to monitor the temperature inside the flower pile, a temperature sensor 201 is provided on one of the drying boards 2. The temperature sensor 201 is vertically arranged to the drying board 2. The detection head of the sensor is located at the center of the flower pile after the jasmine flowers are spread out. The temperature sensor 201 can be connected to an external control chassis. When the internal temperature of the flower pile is monitored to be higher than 38 degrees, the drying board 2 is controlled to rotate to separate the flower pile. The sensor can also be associated with an alarm. When the temperature is too high, an alarm is generated, and the drying board 2 is manually rotated to separate the flower pile to dissipate heat.

[0066] In this device, a swing device 3 is arranged on the side of the frame, and the swing device 3 is used to control the automatic rotation of the drying plate 2 as described above to separate the flower piles for heat dissipation.

[0067] like Figure 4 , Figures 10 to 12As shown, a base 301 is installed on the side of the frame 1, a chassis 302 is installed on the base 301, an inner shaft 311 is rotatably installed in the chassis 302, one end of the inner shaft 311 protrudes from the side of the chassis 302, and a gear 2 306 is provided at the protruding end, and a cam groove 312 is provided on the circumferential surface of the inner shaft 311.

[0068] A sleeve 309 is rotatably sleeved on the outside of the inner shaft 311, and a swing arm 303 is installed at one end of the sleeve 309. At the same time, a mounting hole 310 is opened in a spiral manner on the circumferential surface of the swing arm 303. A movable groove 304 is opened on the top of the chassis 302 along the length direction of the inner shaft 311. The movable groove 304 is opened in a through-type manner, and a slider 307 is installed inside the movable groove 304. A telescopic device 308 is arranged on the top of the slider 307. The telescopic device 308 can be a cylinder or a micro electric push rod in application. When working, the output end of the telescopic device 308 can move through the slider 307, and at the same time pass through the movable groove 304 and the mounting hole 310, and extend into the cam groove 312.

[0069] During operation, when the output end of the telescopic device 308 extends into the cam groove 312, the gear 2 306 rotates, and the output end of the telescopic device 308 moves along the path opened by the cam groove 312. At the same time, it also drives the sleeve 309 and the swing arm 303 at one end of the sleeve 309 to swing back and forth. After the output end of the telescopic device 308 exits the cam groove 312, the gear 2 306 can independently drive the inner shaft 311 to rotate.

[0070] In this device, the shafts at both ends of the drying plate 2 pass through the frame 1 and are fixedly connected to the inner shaft 311, ensuring that the drying plate 2 can be driven to rotate when the gear 2 306 rotates.

[0071] like Figure 4 As shown, in order to enable the swinging effect of the swing arm 303 to drive the drying plate 2 to swing, fan-shaped plates 202 are provided at both ends of the drying plate 2, and round rods 203 are provided at the edges of the fan-shaped plates 202. At the same time, an arc-shaped movable hole 103 is opened on the frame 1, and the end of the round rod 203 passes through the movable hole and at the same time passes through one end of the swing arm 303. Under this setting, the swinging of the swing arm 303 can make the drying plate 2 swing synchronously through the round rod 203, and the purpose of screening flowers is achieved by utilizing the rapid reciprocating swinging of the drying plate 2.

[0072] The driving structure of the swing device 3 is a motor installed inside the chassis 302, and a gear 1 305 driven by the motor output shaft is installed on the outer wall of the chassis 302. The gear 1 305 is meshed with the gear 2 306 to provide driving force.

[0073] When the device is in use, the picked jasmine flowers are spread on the drying board 2, and the leaves are spread evenly to dry the flowers for about 3-4 hours. The flower buds will breathe and generate heat. The temperature of the flower pile gradually rises, forcing the jasmine flowers to gradually open. When the flower buds are about 50% open, the flowers are screened to remove most of the green buds. When screening the flowers, first the two drying boards 2 are rotated to Figure 5 State, at this time, the telescopic device 308 extends the output end into the cam groove 312, the motor drives the gear 305 to rotate, and the airing plate 2 is made to swing back and forth through the swing arm 303, and most of the green buds in the flowers are removed through the sieve holes on the airing plate 2.

[0074] After the first screening, the output end of the telescopic device 308 exits the cam groove 312, and the drying plate 2 rotates to Figure 6 The flowers are gathered into a pile one by one, and the flower pile is kept in a "V" shape, so that the temperature of the flower pile is raised to a suitable temperature again, which promotes the opening of the flower buds. At the same time, when the temperature of the flower pile is too high, the above method can still be used, that is, the drying plate 2 is rotated to Figure 5 state, separate the flower pile to dissipate heat, ensure that the flower buds can open smoothly, and at the same time will not burn the flowers due to excessively high temperature in the flower pile.

[0075] In the process of screening flowers through the drying plate 2, in order to prevent the rejected green buds from falling under the frame, a collecting box 6 is also provided on the frame 1. The collecting box 6 is used to collect the screened green buds. The collecting box 6 is located obliquely below the drying plate 2.

[0076] like Fig. 9 , Figures 13 to 16 As shown in the picture, after the jasmine flowers have been spread out and dried, they need to be scented and pieced together.

[0077] A flower stacking board 7 is arranged on the frame 1 and below the drying board 2. After the flower buds meet the requirements for scenting, the drying board 2 is rotated to Figure 6 The machine frame 1 is rotated again on the basis of the rotation of the flower piling board 7, and the jasmine flowers fall into the flower piling board 7 below, one group of which is also provided with a temperature sensor 201. A swinging device 3 with the same structure as the above is provided on the side of the frame 1 for controlling the rotation state of the flower piling board 7. Unlike the structure of the drying board 2, the side of the flower piling board 7 does not have a sieve structure. At the same time, a tea box 701 for spreading tea leaves is also provided on one side of the frame 1.

[0078] Before the tea leaves are put into the tea box 701, they also need to go through processes such as withering, rolling, and drying. The production process of the tea leaves is not used as an improved technical solution of the present invention, and the tea leaves are produced according to the existing technology.

[0079] A through retreat position 104 is provided on one side of the frame 1, and the tea box 701 can pass through the retreat position 104. At the same time, a retreat groove 102 is also provided on the frame 1 above the retreat position 104. Two auxiliary rods 703 and a screw rod 702 are respectively provided between the frame 1 and the retreat groove 102. The auxiliary rod 703 and the screw rod 702 are both movable through the top protruding part of the tea box 701, and the screw rod 702 is threadedly assembled with the tea box 701.

[0080] A motor for driving the second screw rod 702 is installed on the side of the second retreat groove 102. The motor drives the second screw rod 702 to enable the tea box 701 to move back and forth on the auxiliary rod 703. The tea box 701 spreads the tea leaves along the length direction of the mounding board 7 during the movement.

[0081] In the present device, the bottom of the tea box 701 is tilted, and a feed plate 707 is provided at the end of the tilted part through an axis rotation. The feed plate 707 and the tea box 701 are connected at the axis by a torsion spring assembly (not shown in the figure), that is, the feed plate 707 remains in a closed state without external force. Fig.15 The middle unloading plate 707 is in an open state after being rotated), and the width of the unloading plate 707 protrudes from the side of the tea box 701.

[0082] In order to ensure that the tea leaves can be evenly spread during the movement of the tea box 701, an ear plate 705 structure is provided on the side of the tea box 701, and a contact rod 706 is movable through the ear plate 705. The contact rod 706 is in a "T" structure, and the bottom of the contact rod 706 contacts the protruding side of the unloading plate 707. At the same time, a number of protrusions 704 structures are evenly spaced at the bottom of the auxiliary rod 703. The protrusions 704 structures have different heights. During the movement of the tea box 701, the top of the contact rod 706 continuously contacts the protrusion 704 structure, so that the unloading plate 707 rotates continuously. On the one hand, this process can ensure that the tea leaves are evenly spread on the surface of the jasmine flowers. On the other hand, the slight vibration effect generated by the continuously rotating unloading plate 707 can prevent the tea leaves from being blocked at the unloading port.

[0083] During the process of scenting flowers, jasmine flowers can be dropped in batches by the rotation of the spreading plate 2, so that a layer of jasmine flowers is first laid on the flower piling plate 7, and then the tea box 701 is spread with tea leaves, and the above steps are repeated to drop jasmine flowers again and spread with tea leaves, so that the equipment can completely replicate the process of handmade jasmine tea, achieving a layer of flowers and a layer of tea.

[0084] After the tea and flowers are stacked in layers, they need to be mixed. In this device, the tea is mixed by the swing device 3, which rotates the flower stacking plate 7. Figure 5 state, at this time, the flower stacking plate 7 is reciprocated to achieve tea dressing, so that the tea and flowers are mixed, and after mixing, the flower stacking plate 7 is rotated to Figure 6state, forming a triangular stack, promoting the temperature inside the flower pile to rise to a suitable state. If the temperature of the flower pile is too high, the swing device 3 can rotate the flower stacking plate 7 to Figure 5 state for heat dissipation.

[0085] After the tea flowers are mixed, the tea box 701 spreads a thin layer of tea leaves on the surface of the tea pile to prevent the fresh flowers from being exposed and reduce the loss of fragrance. After 4 to 5 hours, the flowers need to be ventilated to avoid excessive internal temperature. Separating the tea pile is also conducive to promoting the fresh flowers to recover and continue to emit fragrance.

[0086] During the scenting process, the internal temperature is adjusted and the flower stacking plate 7 is rotated to achieve heat dissipation through the flowers. The above steps are repeated for scenting flowers for 10-12 hours. When the flowers lose vitality and the tea leaves absorb moisture and aroma to a certain state, the flowers are started.

[0087] The process of tea blossoming is to separate the camellia flowers, sift out the jasmine flowers, and retain the tea that has absorbed the floral scent.

[0088] In the present device, a vibrating screen 8 is provided on the frame 1 below the flower piling plate 7 for screening and raising the flowers. The vibrating screen 8 contacts the ground through legs. In the technical solution of the present application, the working principle of the vibrating screen 8 is that the screen plate generates vibration through a vibrating motor. The vibrating screen 8 is not used as an improved technical solution of the present invention.

[0089] The flower stacking plate 7 drops the flowers and tea into the vibrating screen 8 through the swinging device 3 to screen the flowers and tea.

[0090] Since jasmine flowers are fresh and rich in moisture, the tea not only absorbs the fragrance of the flowers but also absorbs moisture after it blooms. The tea is moist and needs to be re-fired to dry it. It can then be used after the temperature of the tea drops.

[0091] Therefore, a drying plate 9 is provided on the frame 1 below the vibrating screen 8, and the tea screened by the vibrating screen 8 falls into the drying plate 9. Both ends of the drying plate 9 are mounted on the frame 1 through a rotating shaft, wherein the mounting position of the shaft is biased toward one side of the frame 1, so that the drying plate 9 can rotate to one side in a natural state, which is convenient for collecting the scented tea after drying.

[0092] A latch 901 is also provided on the frame 1 and is located below the drying plate 9. The latch 901 is inserted to keep the drying plate 9 parallel when sifting tea.

[0093] The frame 1 is provided with a heating plate 10 below the drying plate 9 for heating and drying the drying plate 9 .

[0094] In the invention, the heating plate 10 can be heated by setting a resistance wire inside the heating plate 10 through electric heating, or charcoal fire can be placed in the heating plate 10 to replicate the traditional manual baking method.

[0095] This equipment is very suitable for various small and medium-sized jasmine tea processing factories. According to the needs of the tea factory, the length of the frame 1 of this equipment can be set to 1-3 meters, and the height can be set to about 1.4 meters, which is convenient for observing the tea and flower piles. At the same time, compared with the existing equipment, this equipment can completely replicate the process of hand-made jasmine tea, compared with the traditional hand-made jasmine tea, but at the same time it greatly reduces the manual operation process. The rotation of the drying board 2 and the flower pile board 7 in this equipment can be controlled by a motor with a brake, and the temperature monitoring of the tea pile and the flower pile can be automated. There is no need for tea workers to observe the temperature of the tea pile and the flower pile all the time, nor is there any need for manual heat dissipation through the flowers, thereby reducing the amount of work for workers.

[0096] The inner side of the drying board 2 and the flower piling board 7 in the present device can adopt a thin wood board embedding process, that is, a layer of wood board is laid on the surface of the drying board 2 and the flower piling board 7 to prevent the flowers and tea from directly contacting with the metal, which would cause the outer layer of flowers and tea to cool down too quickly. Small equipment can also be made directly of wood.

[0097] The present invention also relates to a jasmine tea processing method, which adopts the above-mentioned equipment for processing and comprises the following steps:

[0098] Step 1, picking and spreading the flowers to dry: picking the buds about to bloom at noon, pouring the jasmine flowers from one end into the drying board 2, and spreading the jasmine flowers with the spreading blades, the thickness of which is controlled to be about 10CM, the temperature sensor 201 monitors the temperature of the flower pile, when the temperature is higher than 38, the drying board 2 rotates to separate the flower pile for heat dissipation, and the air duct 5 can be activated for forced heat dissipation when necessary, and the flowers are gathered into a pile again when the temperature is suitable to promote the temperature of the flower pile and make it bloom.

[0099] Step 2, flower scenting and splicing: after the jasmine flowers open to the requirements on the spreading plate 2, they fall to the flower piling plate 7, and the spreading plate 2 is rotated to achieve batch falling. Each layer of flowers that falls is spread with a layer of tea blanks through the tea box 701. About 2-3 layers can be spread, and the ratio of tea to flowers is controlled at 1:1. After spreading, the flower piling plate 7 is swung by the swinging device 3 to mix the camellia flowers, and then gathered into a pile. Finally, a thin layer of tea blanks is spread on the surface again to avoid waste of flower fragrance. The flowers are scented for about 8-10 hours.

[0100] During this process, the temperature of the tea pile is monitored. When the temperature is too high, the tea pile is still rotated by the flower stacking plate 7 to separate the tea pile and dissipate the heat.

[0101] Step 3, sieving and separating the flowers: After the scenting time is sufficient, the flower fragrance dissipates, the flower stacking plate 7 rotates, and the scented tea falls to the vibrating screen to sieve the flowers and tea.

[0102] Step 4, re-firing the scented tea: After being sieved and scented, the tea leaves fall into the drying plate 9, and the heating plate 10 is heated to dry the moisture absorbed by the tea leaves during the scenting process.

[0103] The above complete steps are for one scenting, and the scenting can be performed multiple times depending on the quality of the scented tea.

[0104] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
