Description

Technical Field

[0001] The invention belongs to the technical field of tea processing, and in particular relates to a processing technology for removing the bitter taste of summer tea and special processing equipment thereof. Background Art

[0002] The tea picking period in major tea-growing areas in my country is generally in spring, summer and autumn. Generally speaking, spring tea has the best quality and the highest yield. Summer and autumn tea is not as good as spring tea, with relatively low benefits and serious abandonment. The reason is that the temperature is suitable for spring tea, the temperature difference between day and night is large, the sunshine is weak, and there is a lot of diffuse light. In addition, from October of the previous year to March of the current year, a large amount of nutrients are accumulated in the six months, especially the protein in the tea leaves, which has a high amino acid content, making the finished tea taste mellow and sweet.

[0003] The climate of summer and autumn tea is hot and dry, with long sunshine hours, strong ultraviolet rays, and small temperature difference between day and night. The content of amino acids, proteins and vitamins in tea leaves in summer and autumn is significantly reduced, resulting in high content of tea polyphenols, anthocyanins and caffeine in tea leaves, which leads to bitter taste of finished tea. Therefore, when making black tea, people usually only pick spring tea or early summer tea with relatively low temperature. However, there is also summer and autumn tea, which accounts for about 40% of the total annual output. Because its bitter taste cannot be improved and its quality is poor, the product price can only be maintained at a low level, and the enthusiasm of producers is not high, resulting in the phenomenon that only spring tea is picked in many tea areas, and summer and autumn tea is not picked, which causes serious waste of resources. If a process and equipment that can effectively change the bitter taste of summer and autumn black tea is developed, the quality of summer tea can be further improved, which can not only achieve better economic benefits, but also has important significance for the sustainable development of the tea industry. Summary of the invention

[0027] The second frame is also provided with a driving mechanism for driving the second rotating shaft to rotate.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. By pruning the picked spring tea leaves at the end of April and applying fertilizer, the growth of tea leaves can be promoted, which is beneficial for the new buds of tea leaves to grow stronger. In addition, under the influence of the rainy season, the new buds can grow to more than 2 cm, laying a good raw material foundation for high-quality summer and autumn black tea.

[0030] 2. The picking period is around 6:00 to 11:30 am every day. Because there is no sunshine the night before and the sunshine in the morning is relatively weak, the strong sunshine at noon and in the afternoon is avoided. There are relatively fewer bitter substances in the fresh leaves, and the bitterness of the black tea made from the fresh leaves is lighter. The bitterness can be controlled from the picking stage of the tea leaves; the picked new buds are spread at a temperature below 18°C ​​and maintained in a high humidity and thin spread state. Therefore, under the conditions of low temperature and low thickness, tea polyphenols, anthocyanins, caffeine content and other substances will be inhibited, and the bitterness of the tea can be greatly reduced. In addition, the spreading time is tripled compared to the traditional process, which can further reduce the bitterness and improve the overall quality of summer tea.

[0031] 3. The equipment provided by the present invention can effectively control the spreading of new buds of summer tea, especially after the newly picked tea leaves are spread on the first distribution piece and the second distribution piece, they can be placed in a cold storage or a cold storage workshop according to actual conditions. The spreading time and screening of the tea leaves can be automatically completed by the equipment without manual processing, thereby reducing the changes in temperature and turning caused by personnel entering and exiting, thereby ensuring the overall consistency and quality of the tea leaves.

[0032] 4. The equipment provided by the present invention can realize the operation of combining two screens into one screen for the spread new buds, as well as the operation of combining screening and collection after the spreading time is reached. During the process of combining screening, the roller is driven to rotate through the movement of the support rod, thereby driving the first rotating shaft and the first thin rod to rotate, and the tea leaves on the first spreading part are merged into the second spreading part. By driving the second rotating shaft and the second thin rod to rotate, the tea leaves on the second spreading part can be sent to the collecting bucket for storage and collection, thereby realizing a rapid combining screening operation; and when the tea leaves on the first spreading part are transferred to the second spreading part, the second spreading part moves up and down, and can vibrate under the action of the rack and the contact seat, so that the tea leaves on the second spreading part can be vibrated evenly, and when the second spreading part moves to the topmost position, the tea leaves on the second spreading part can be turned over by the rotation of the first spreading net, so as to avoid water accumulation after hours of spreading.

[0033] 5. The first spreading net can be set up so that the locking platform and the locking groove are clamped together under the action of the push rod, so as to maintain the horizontal arrangement state of the first spreading net, so as to achieve the effect of normally holding tea leaves. After the first frame is inserted into the limit plate, the limit plate will push the push rod, so that the locking platform will no longer clamp the locking groove. At this time, the first spreading net can be rotated. Therefore, when the movable seat is active, it can drive the first spreading net to rotate, so that the tea leaves on the first spreading net will fall off. When the first spreading net is arranged horizontally, it only needs to pull out the control line and straighten it to flatten the first spreading net. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] The following is the overall evaluation given by the volunteers after drinking the above different teas:

[0106]

[0107] It can be seen that making summer tea according to the process of the present application can significantly reduce the bitterness in the tea and improve the quality of the tea.

[0108] In order to smoothly implement the spreading of step 3, the present invention also provides a special processing tool for removing the bitter taste of summer tea, please refer to the attached manual Figure 1-12 As shown, the tool includes a frame 10. Specifically, the frame 10 is a support frame made of aluminum alloy. A plurality of groups of first apportionment members 11 and second apportionment members 12 are detachably provided on the frame 10. Each of the first apportionment members 11 and the second apportionment members 12 is a group, and are arranged on the frame 10 from bottom to top in sequence. A collecting bucket 13 for collecting tea leaves is provided below the first apportionment member 11 and the second apportionment member 12 at the bottom. The collecting bucket 13 is detachably arranged on the frame 10, and a slide groove for installing the collecting bucket 13 is provided on the frame 10. When installing, the edge of the collecting bucket 13 can be inserted into the slide groove along the edge.

[0109] The first distributing member 11 includes a first frame 111 and a first distributing net 112 movably disposed on the first frame 111. Figure 8 As shown, the second apportionment member 12 includes a second frame 121 and a second apportionment net 122 movably disposed on the second frame 121. Fig. 9 As shown, when the first distributing net 112 is active, the tea leaves on the first distributing part 11 are poured into the second distributing part 12. The tea leaves on the first distributing part 11 are poured into the second distributing part 12 after being spread for 48 hours, completing the automatic processing of two screens into one screen. When the second distributing net 122 is active, all the tea leaves are poured into the collecting bucket 13 for collection. The tea leaves can be collected after being spread.

[0110] like Figure 3 , 4As shown in FIG. 5 , as a preferred embodiment of the above embodiment, the first sharing network 112 includes a plurality of first rotating shafts 1121 and a plurality of first thin rods 1122 fixedly arranged on the first rotating shafts 1121. The first rotating shafts 1121 are rotatably arranged on the first frame 111, and a roller 113 is fixedly arranged at one end of the first frame 111.

[0111] The frame 10 is fixedly provided with a support rod 14 for supporting the first frame 111. Figure 4 As shown, the support rod 14 is in an "L" shape, and the top of the support rod 14 supports the first frame 111. A limiting plate 25 for limiting the first frame 111 is fixedly provided on the support rod 14. A movable seat 15 is also slidably provided on the support rod 14 to drive the roller 113 to rotate so as to pour out the tea leaves spread on the first spreading net 112. The movable seat 15 is connected to a first driving source. Specifically, the first driving source includes a motor fixedly arranged on the top of the frame 10, and the motor is connected to the controller through wires. The controller can be set to a timing as needed; the motor is connected to a reducer, and the output shaft end of the reducer is connected to A main shaft is provided, and the internal thread of the movable seat 15 is connected to a bidirectional threaded drive shaft. The bidirectional threaded drive shaft and the main shaft are mutually arranged through gear transmission. Therefore, after the preset time is reached, the main shaft is driven to rotate by the motor, thereby driving all the movable seats 15 to move back and forth on the support rod 14, which can drive the first spreading net 112 to rotate, so that the tea leaves on the first spreading net 112 can fall onto the second spreading member 12. In addition, since the first thin rods 1122 on different first rotating shafts 1121 are arranged in an interlaced manner, it is easier for the tea leaves to fall when the first spreading net 112 rotates.

[0112] like Figure 4 , 8 , 10, 11, and 12, as a preferred embodiment of the above embodiment, a joint column 115 is fixedly provided at the other end of the first rotating shaft 1121, and the diameter of the joint column 115 is larger than the diameter of the first rotating shaft 1121. A through hole 116 is completely penetrated on the joint column 115, and a control line 114 is passed through the through hole 116. Fig.11 ;

[0113] The end of the joint column 115 is provided with a locking groove 117, and a partition cover 16 is fixedly provided on the outer side of the first frame body 111 to close the joint column 115. A push rod 17 is elastically provided in the partition cover 16. Specifically, a mounting seat for sleeve-connecting the push rod 17 is provided at one end of the partition cover 16, and a spring is provided in the mounting seat to push the push rod 17 outward. The other end of the push rod 17 passes through the partition cover 16, and a plurality of locking platforms that can be mutually engaged with the locking groove 117 are provided on the push rod 17. 171, so under normal circumstances, the spring pushes the push rod 17 to move toward the end that penetrates the partition cover 16. After the first distributing member 11 is installed on the limiting plate 25, the end of the push rod 17 that penetrates the partition cover 16 contacts the limiting plate 25 and then retracts into the partition cover 16, and the locking platform 171 loses its clamping effect on the locking groove 117. When the locking platform 171 is clamped into the locking groove 117, the entire first distributing member 11 is not installed on the frame 10. Therefore, under the push of the spring, the first distributing member 11 is not installed on the frame 10. The entire first spreading net 112 can be kept in a horizontal arrangement state when moving, and cannot be rotated at will, so as to effectively maintain the effect of spreading the tea leaves. After being installed on the frame 10, the locking platform 171 loses the clamping effect on the locking groove 117, so the first spreading net 112 can be rotated freely, and the set control line 114 can be stretched and tightened, and then quickly flattened to facilitate the next spreading of tea leaves. Moreover, as another embodiment, a winding device 26 that can automatically reel in the control line 114 can be provided on the side of the first spreading member 11. The winding device 26 is internally driven by a spring to rotate the winding roller. In this way, when the first spreading net 112 rotates, a large amount of wire is prevented from being pulled into the partition cover 16 to produce knots and the like. In this way, the horizontal arrangement of the first spreading net 112 can be maintained at any time, and the effect of pouring out tea leaves when the first spreading net 112 rotates can also be maintained.

[0114] like Figure 3 , 4 As shown in Figures 5, 6, 7 and 9, as a preferred embodiment of the above embodiment, the second sharing network 122 includes a plurality of second rotating shafts 1221 rotatably arranged with the second frame 121, a plurality of second thin rods 1222 are fixedly arranged on the second rotating shafts 1221, and the second thin rods 1222 on different second rotating shafts 1221 are arranged in straight lines and staggered with each other;

[0115] A first connecting rod 123 is fixedly disposed at one end of the second rotating shaft 1221, and a plurality of second sharing nets 122 are connected to each other through a second connecting rod 124. Figure 7 , 9 The second connecting rod 124 and the first connecting rod 123 are mutually rotatably arranged, and the second frame body 121 is also provided with a driving mechanism for driving the second rotating shaft 1221 to rotate. The driving mechanism can refer to the attached Figure 6As shown, it includes a rotating handle rotatably arranged on the second frame 121, and the rotating end of the rotating handle and the second rotating shaft 1221 are mutually transmitted through gears. Therefore, when the rotating handle is turned, all the second rotating shafts 1221 can be driven to rotate, so that the tea leaves on the second sharing net 122 can fall off.

[0116] As a preferred embodiment of the above embodiment, a slide rail 18 is fixedly provided on the frame 10. Figure 6 A slide seat 19 is slidably provided on the slide rail 18, and a mounting seat 20 is fixedly provided on the slide seat 19 for facilitating the installation and placement of the second frame 121. A groove 201 is provided on the top of the mounting seat 20 for facilitating the placement of the second frame 121, and a tenon 202 is elastically provided inside one of the grooves 201. A movable rod 21 that moves up and down is provided on one side of the frame body 10, and a lifting plate 22 that is fixed to the mounting seat 20 is fixed on the movable rod 21; Figure 3 The top of the movable rod 21 is connected to a second driving source that drives it to move up and down. Specifically, the structure of the second driving source includes a second motor fixedly arranged on the top of the frame 10. The second motor is also connected to the controller through wires. The output shaft of the second motor is connected to a gear after being decelerated by a reducer. Two symmetrically arranged racks are meshed on the gear. The direction of the rack is the same as the axial direction of the second rotating shaft 1221 of the frame 10. A gear rack mechanism is set again at the end of the rack. The output rack is arranged in a vertical direction and is fixed to the movable rod 21. In addition, a rack 23 is fixedly arranged on the frame 10, and a tooth surface that is aligned with the rack 23 is fixedly arranged on the slide 19. Specifically, the slide rail 18 guides the slide seat 19 in the up and down directions, and there is a gap between the slide rail 18 and the slide seat 19. When the second spreading member 12 moves in the up and down directions, the contact seat 24 and the rack 23 can be in contact with each other to drive the second spreading member 12 to vibrate, so that the tea leaves on the second spreading member 12 are vibrated evenly, especially when the second spreading member 12 is lifted to the top, by driving the first spreading net 112 to rotate, the tea leaves on the second spreading member 12 can be turned over during the rotation of the first spreading net 112, so that after 48 hours of spreading, the phenomenon of waterlogging of tea leaves can be avoided due to long-term spreading.

[0117] The bottom of the second frame 121 is detachably provided with a receiving frame 125 for receiving the debris. Figure 6 The second connecting rod 124 is installed at the bottom of the second frame 121 when spreading, and plays the role of receiving the debris generated during the vibration process. After spreading, the second connecting rod 124 is first removed from the second frame 121, and then the second spreading net 122 is rotated to collect the tea leaves from top to bottom.

[0118] The specific working principle of the present invention is as follows: first, the picked fresh leaves are evenly spread on the first distribution member 11 and the second distribution member 12 as required, and then the first distribution member 11 and the second distribution member 12 are installed on the frame 10, and the frame 10 is pushed into a cold storage or a cold storage workshop, the ambient temperature is set, and the first driving source and the second driving source are connected to the controller;

[0119] When spreading the tea leaves 48 hours ago, no operation is performed. After 48 hours, the controller drives the first driving source to control the first spreading net 112 to rotate and pour the tea leaves on the first spreading member 11 into the second spreading member 12 for screening. At the same time, the controller controls the second driving source to drive the second spreading member 12 to move up and down. On the one hand, the fallen tea leaves are vibrated evenly. On the other hand, when the tea leaves move to the top, the rotation of the first spreading net 112 can turn over the tea leaves on the second spreading member 12, thereby preventing the tea leaves on the second spreading member 12 from being soaked until the predetermined stall time is reached.

[0120] Finally, when the tea leaves are taken out, the second connecting rod 124 is first removed, and then the second distributing net 122 is rotated from top to bottom in sequence, so that the tea leaves can be collected into the collecting bucket 13 in sequence.
