[0001] The invention relates to the technical field of tea processing, in particular to a device for blending and stacking pine needle tea for export. Background Art

[0002] my country is a major tea exporter, with green tea and black tea being the main export products. In order to meet the taste requirements of different countries, tea for export usually needs to be blended to achieve the desired taste. Songluo tea is a famous historical tea, which is deeply loved by customers at home and abroad. Before being exported, Songluo tea also needs to be further refined, processed and blended.

[0003] The refined blending of Songluo tea for export, the existing method is to first re-dry tea leaves from different origins and different seasons to enhance the fragrance, and then add a blending and leveling machine to mix and blend according to a certain proportion, so that the color of the appearance and the taste, soup color and aroma of the internal quality are consistent, and meet the quality requirements of foreign merchants for finished Songluo tea for export. Therefore, this aroma enhancement sterilization and blending and leveling process is an important process for the refined processing of Songluo tea for export, which is directly related to the quality and export. However, production practice shows that as a "spiral" Songluo tea, the current aroma enhancement sterilization and blending and leveling process and equipment do have three major technical limitations: First, the first re-drying aroma enhancement sterilization and then blending and leveling process makes it easy for Songluo tea to get damp on rainy days, and it is difficult to maintain a strong aroma. Second, the turning claw leaf leveler configured by the existing box-type tea leveling machine cannot stir the "spiral" tea evenly, resulting in poor blending and leveling effect. Thirdly, it is difficult for the existing blending and stacking equipment to remove the "fuzz" contained in the spiral tea, which results in "spindle-shaped suspended matter" floating on the upper layer of the Songluo tea after brewing. Foreign businessmen consider these impurities in the tea to be unacceptable, thus affecting the export of Songluo tea. Summary of the invention

[0027] Examples, such as Figures 1 to 7 As shown, a machine for blending, leveling and flavoring of Songluo tea for export comprises a blending and leveling conveying device 1, a leveling and impurity removing cylinder 2, a flavoring, sterilizing and leveling drum 3 and a discharging and impurity removing vibration trough 4 which are connected in sequence.

[0028] Specifically, the blending and mixing conveying device 1 includes a set of weighing feeding belts 11, at least three of which are stainless steel mesh conveying belts. A tea storage hopper 16 is provided at the feeding end of the weighing feeding belts 11, and a mixing hopper 12 is provided at the discharging end of the weighing feeding belts 11. Spiral tea produced in different origins and seasons is transported into the mixing hopper 12 through each weighing feeding belt 11 for mixing. In order to accurately control the proportion of various teas to meet the needs of different customers, a weighing hopper 17 is connected to the bottom of the tea storage hopper 16, and a solenoid valve 18 for controlling the falling of tea leaves is arranged between the tea storage hopper 16 and the weighing hopper 17. A weighing base plate 19 that can be opened and closed is arranged at the bottom of the weighing hopper 17. The specific structure can adopt a rotating manner to move the weighing base plate 19 out from under the weighing hopper 17, that is, a rotating shaft 191 is arranged on the weighing hopper 17, and the rotating shaft 191 is driven by a motor. The weighing base plate 19 is fixed to the rotating shaft 191 by a connecting rod or the outer edge of the weighing base plate 19 is directly welded and fixed to the rotating shaft 191. The rotating shaft 191 rotates to drive the weighing base plate 19 to rotate, so that the weighing base plate 19 enters under the weighing hopper 17 or moves out from under the weighing hopper 17. In order to prevent the tea from staying on the weighing bottom plate 19 when the weighing bottom plate 19 is removed, a circle of flexible rubber retaining ring 171 is provided at the bottom of the weighing hopper 17, and the flexible rubber retaining ring 171 is used to sweep the tea on the weighing bottom plate 19 onto the material mixing conveyor belt 14. In order to preliminarily mix the tea entering the batching hopper 12, a batching device 13 for mixing and stirring the tea is provided in the batching hopper 12. The batching device 13 includes a batching shaft 131 and a group of batching blades 132 mounted on the batching shaft 131. The batching blades 132 are concave cambered structures and are distributed in the shape of fan blades on the batching shaft 131. The batching shaft 131 is driven by a motor to drive the batching blades 132 to rotate, so that the tea conveyed from each weighing feed belt 11 is mixed. The batching blades 132 adopt a concave cambered structure and are distributed in the shape of fan blades to increase the strength of mixing and blending.

[0029] A mixing conveyor belt 14 is provided below the discharge end of the batching hopper 12, and the mixed tea leaves are sprinkled onto the mixing conveyor belt 14 through the discharge end of the batching hopper 12. The mixing conveyor belt 14 is a stainless steel inclined mesh conveyor belt. In order to increase the mixing force, a group of first turners 15 for turning the tea leaves are provided at intervals of 60-70 cm on the conveyor belt. The first turner 15 includes a first rotating shaft 151, and a group of turner plates 152 installed on the first rotating shaft 151 at intervals. The turner plates 152 are curved crescent-shaped, and the two ends of the turner plates 152 are fixed on the first rotating shaft 151. There is a material drop gap 153 between the turner plates 152 and the first rotating shaft 151, and the rotation directions of the two adjacent first turners 15 are opposite. The first rotating shaft 151 is driven by a motor to drive the turner plates 152 to rotate, and the tea leaves on the mixing conveyor belt 14 are picked up and turned over.

[0030] The discharge port of the mixing conveyor belt 14 is connected to the feed port of the mixing and impurity removal cylinder 2 through the Z-type conveyor belt 5. In order to make the tea leaves evenly fall on the cylinder of the Z-type conveyor belt 5, the discharge port of the mixing conveyor belt 14 is also provided with a first distributor 110 in the shape of a fan structure.

[0031] The material mixing and impurity removal cylinder 2 includes a cylindrical cylinder body 21, which is a cylindrical stainless steel material, and adopts a "vertical" method to mix and impurity remove. The height of the cylinder body 21 is 1.4M and the diameter is 1.1M. The bottom of the cylinder body 21 is provided with a screen bottom cover 22 that can be opened and closed for discharging. The screen mesh number of the screen bottom cover 22 is 12 meshes, and a dust bag 27 is set under the screen bottom cover 22. The top of the cylinder body 21 is provided with an openable and closable screen upper cover 23, and the screen mesh number of the screen upper cover 23 is 14 meshes. The first negative ion fan 24 is provided on the screen upper cover 23, and the first negative ion fan 24 is connected to the first debris collection bag 25. The opening method of the bottom cover 22 and the screen upper cover 23 can adopt the same rotation opening method as the weighing bottom plate 19, which will not be repeated here.

[0032] The cylinder 21 is also provided with a mixer 26, which includes a mixer shaft 261 and a group of stirrers 262 installed on the mixer shaft 261. The screen upper cover 23 is opened to feed the tea leaves, so that the tea leaves on the mixer conveyor belt 14 fall into the cylinder 21, and then the screen upper cover 23 and the screen bottom cover 22 are closed. The mixer 262 is driven by the motor to rotate the mixer shaft 261 in the cylinder 21, and the tea leaves in the cylinder 21 are continuously stirred to make the mixing more uniform. At the same time, the hair and dust entrained in the spiral tea leaves are raised, and the hair and dust are absorbed into the first debris collection bag 25 by the first negative ion fan 24. At the same time, some heavier impurities fall into the dust bag 27 through the sieve holes of the screen bottom cover 22, and the mixing and impurity removal are completed.

[0033] The stirrer 262 is a semicircular leaf-turning plate, on which a group of holes are arranged, and the diameter of the holes is 3-5 mm. There are three stirrers 262 in total, each of which is installed on the mixer shaft 261 at an interval of 40 cm and staggered. The structure of the stirrer 262 can reduce the resistance of the tea leaves during stirring, and the holes can allow small tea particles to pass directly without being squeezed and broken, thereby effectively reducing the breakage of spiral tea during mixing.

[0034] The discharge port of the mixing and impurity removal cylinder 2 is located above the feed port of the aroma-enhancing, sterilizing and stacking drum 3. When the mixing and impurity removal cylinder 2 completes the mixing, the screen bottom cover 22 at the bottom is opened to allow the tea leaves to fall into the aroma-enhancing, sterilizing and stacking drum 3 below, and the tea leaves are re-dried and sterilized by the aroma-enhancing, sterilizing and stacking drum 3.

[0035] The aroma-enhancing, sterilizing and stacking drum 3 includes a drum body 31 and an electromagnetic heating device 32 arranged below the drum body 31. The drum body 31 is a cylindrical drum made of composite steel, which is aroma-enhancing and stacked in a "horizontal" manner. The size of the drum body is 1500×1100mm. In order to prevent the aroma-enhancing, sterilizing and stacking tea leaves from piling up at the discharge port of the drum body 31, three baffles 34 with a height of 15cm, a width of 0.3cm and an inclination of 17 degrees are arranged along the circumferential direction at a distance of 20cm from the discharge port. The structural principle of the baffles 34 is the same as that of the inlet and outlet guide vanes of the existing tea drum withering machine. When the drum body 31 rotates clockwise, the tea leaves are aroma-enhancing, sterilizing and stacking. When the drum body 31 rotates counterclockwise, the tea leaves are discharged under the guidance of the baffles 34.

[0036] The drum body 31 is rotatably mounted on the electromagnetic heating tank 321. A stacking device 33 is arranged in the drum body 31 in the opposite direction of the rotation direction of the drum body 31. When the drum body 31 rotates forward to improve the aroma, the stacking device 33 is reversed to reversely turn the tea leaves so that they can fully receive the electromagnetic radiation heat to improve the aroma. When the drum body 31 is turned out, the stacking device 33 rotates forward to push the tea leaves out of the discharge port. The stacking device 33 includes a rotating shaft 331 arranged in the drum body 31, and a group of stacking blades 332 installed on the rotating shaft 331 at intervals. The rotating shaft 331 has a shaft length of 1.2M and a diameter of 0.3cm. The stacking blades 332 are crescent-shaped flat plate structures, which can improve the efficiency of stacking and reduce the breakage of pine tea. The tea leaves in the drum body 31 are fully turned and stirred by the stacking device 33, so that the tea leaves are evenly heated, and the efficiency of drying and improving the aroma is improved. At the same time, a gap of one third is left between the stacking blades 332 and the inner wall of the drum body 31 to prevent the tea leaves from being squeezed and broken.

[0037] The electromagnetic heating device 32 includes an electromagnetic heating tank 321, and an electromagnetic heating plate 322 is arranged in the electromagnetic heating tank 321. There are three electromagnetic heating plates 322, which are arranged in the electromagnetic heating tank 321 at intervals of 45 cm. The electromagnetic radiation heat is used to promote the volatilization of aromatic substances in the tea leaves and improve the aroma of the pine tea, while also killing microorganisms. In order to maintain uniform radiation heating and avoid direct electromagnetic radiation from burning the tea leaves, a partition 323 is provided between the electromagnetic heating tank 321 and the drum body 31. The partition 323 is made of quartz material and is evenly distributed with laser micropores to balance the heat and mitigate electromagnetic radiation.

[0038] In order to monitor the temperature and humidity of the tea leaves in the drum body 31 and adjust the temperature of the electromagnetic heating plate 322, a temperature and humidity sensor 36 is provided at the discharge end of the drum body 31. The temperature and humidity sensor 36 is a MIK-TH800 temperature and humidity sensor. Its multi-sensing probe is arranged at a position 20-30 cm away from the discharge port of the drum body 31, and is connected to the controller to timely adjust the temperature and humidity of the aroma-enhancing sterilization pile to ensure that the moisture content of the Songluo tea is ≤5.5% when it is discharged.

[0039] The discharging port of the aroma sterilization and stacking drum 3 is connected to the discharging and impurity removal vibration trough 4. The discharging port of the drum body 31 is also provided with a second distributor 35 in the shape of a fan, and the tea leaves are evenly scattered on the feeding end of the discharging and impurity removal vibration trough 4 through the second distributor 35. The discharging and impurity removal vibration trough 4 includes a trough body 41 and a vibrator 42 that drives the trough body 41 to vibrate. The trough body 41 is arranged at an angle of 10-12 degrees, and the material is discharged smoothly from high to low. The trough body 41 is made of stainless steel, with a length of 2.4M, a width of 0.8M, and a depth of 0.6M. The bottom plate of the trough body 41 is a 12-mesh screen structure. The vibrator 42 is a JMC-30 ratchet pneumatic vibrator, which is arranged at 15-20cm at the rear of the trough body 41 to generate vibrations with a frequency of 500-600 times / min, so as to drive the trough body 41 to discharge the material and screen out the broken tea leaves.

[0040] In order to ensure that the tea leaves are mixed and transported after aromatherapy and sterilization, and to remove the broken tea leaves produced during the processing, a group of second material turners 43 are arranged at intervals in the tank body 41. Preferably, the second material turner 43 includes a stirring dragon 431 rotatably mounted on the tank body 41, and a group of material turning claws 432 arranged on the stirring dragon 431. The stirring dragon 431 is made of stainless steel, 2.1M long and 25cm in diameter, and is driven to rotate by a motor. The stirring dragon 431 has a higher stirring force due to its large diameter. The stirring dragon 431 is arranged along the feeding direction of the discharging and impurity removal vibration tank 4, and the material turning claws 432 are installed on the stirring dragon 431 at intervals. The material turning claws 432 are five-finger-shaped, and this structure can reduce the damage to the tea leaves when turning. The stirring dragon 431 drives the material turning claws 432 to fully turn and mix the tea leaves on the tank body 41, and at the same time, the broken tea foam entrained therein falls from the bottom plate screen of the tank body 41.

[0041] Further, the discharging and impurity removal vibration trough 4 includes an outer cover 44 covering the trough body 41, and the outer cover 44 is made of a 100-mesh stainless steel screen. A second negative ion fan 45 is arranged on the outer cover 44, and the second negative ion fan 45 is connected to a second debris collection bag 46. The negative ion wind of the second negative ion fan 45 rotates at a high speed to remove the hair, dust and foreign matter attached to the tea leaves, and the static electricity in the tea leaves, and also absorbs the hot and warm cooling tea leaves. This machine is equipped with a discharging and impurity removal vibration trough, which can not only efficiently remove the hair, dust and static electricity attached to the tea leaves, so that the cleanliness reaches more than 98%, but also absorbs the hot and warm cooling tea leaves to achieve the "cold packaging" of Songluo tea and prevent the quality from being affected by high-temperature oxidation. In order to further reduce the breakage rate during the blending and stacking, the semicircular arc-shaped leaf turning plate on the stirrer, the stacking blade on the stacker and the turning claw on the second material turning device are all covered with a layer of plastic soft cover, which can not only efficiently stir and stack, but also reduce the breakage of Songluo tea.

[0042] The discharging end of the discharging and impurity removal vibration trough 4 is directly connected to the tea packing machine. The second negative ion fan on the discharging and impurity removal vibration trough 4 will also absorb the heat and cool the tea leaves to achieve "cold packaging" of Songluo tea and prevent the quality of the tea leaves from being affected by high heat oxidation.

[0043] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
