Description
Technical Field
[0001] The invention relates to the technical field of black tea processing equipment, in particular to integrated black tea processing equipment. Background Art
[0002] As a beverage widely consumed around the world, the quality of black tea directly affects consumers' taste experience and health. The traditional black tea processing process includes multiple steps such as rolling, fermentation and drying after withering. These steps are often carried out independently in different equipment, and the equipment needs to be transported back and forth one by one. The low degree of automation is not only inefficient, but also difficult to ensure the consistency of black tea quality.
[0003] In the production process of black tea, the tea leaves rolled by the rolling machine cannot be automatically output at one time due to the structural characteristics of the rolling machine's grinding disc. They need to be manually cleaned up from around the grinding disc, collected and then transported to the fermentation box for fermentation. In the fermentation process, multiple layers of black tea are often piled up at once. During fermentation, it is difficult to stir the inside, resulting in a high temperature in the center of the black tea and inconsistent fermentation temperature. Not only is the fermentation operation efficiency low, but its fermentation quality is also greatly reduced.
[0004] Therefore, designing an integrated black tea processing equipment to realize the full automated production and transportation from rolling to drying of finished products is of great significance to improving the efficiency and quality of black tea processing. Summary of the invention

DETAILED DESCRIPTION
[0025] This specification will clearly and completely express the technical solutions in the following examples based on the drawings of the embodiments of the present invention. The implementation methods described in this specification are only some of the embodiments of the present invention, not all of them. All other embodiments extended and inspired by those skilled in the art based on these embodiments in this application without creative work should fall within the scope of protection of the present invention.
[0026] like Figure 1The integrated processing equipment for black tea shown in the figure mainly includes a rolling machine, a fermentation box 9 and a drying box connected in sequence. Specifically, the grinding disc 1 of the rolling machine is horizontally installed in a casing 4 through a support shaft 3 arranged along its radial direction. The support shaft 3 is fixed to the bottom of the grinding disc 1, and the two ends of the support shaft 3 are rotatably installed on the two opposite side walls of the casing 4, and one end can be installed with a motor for transmission, and the motor is adaptively fixed to the outer wall of the casing 4. In this way, as long as the motor rotates, the entire grinding disc 1 can be tilted downward to pour out the black tea scattered on the grinding disc 1 after rolling, that is, the support shaft 3 is driven by a transmission device and can rotate 90° downward around its own axis, so that the grinding disc 1 is in a vertical state and the rolled black tea is poured out. In practice, it is best to process the housing 4 into a structure with a V-shaped cross section, which is roughly like a boat, but the bottom is gradually inclined downward. When the tea storage cylinder 6 arranged above the grinding disc 1 moves on the horizontal plane above the grinding edge 2 on the grinding disc 1, the tea leaves leaking from the tea storage cylinder 6 can be in friction contact with the grinding edge 2 to complete the rolling. In order to improve the rolling efficiency, it can be as follows Figure 1 As shown, there is a truncated cone at the intersection of all the grinding edges 2 in the circular array. The circular array on the top surface of the truncated cone has secondary edges 7 so as to timely rub and contact with the large amount of black tea falling from the center and scrape it to the surroundings. Specifically, the rolling machine in this embodiment is basically similar to the structure of the traditional rolling machine, and its specific principles are recorded in the prior art. The tea storage cylinder 6 on the rolling machine, that is, a container pre-filled with black tea, can adjust the vertical spacing distance relative to the grinding disc 1 to allow the tea leaves to flow down better and then contact the surface of the grinding disc 1. When the tea storage cylinder 6 moves in a plane above the grinding disc 1, the black tea is rolled and gradually moves toward the outer edge so that new black tea can continue to flow down and be gradually rolled. In this embodiment, there can be a valve plate at the bottom of the tea storage cylinder 6 to close the tea storage cylinder 6, so that when the rolling is not complete in the middle, the tea storage cylinder 6 can be moved upward so that the grinding disc 1 can pour the rolled black tea downward in the middle. At the same time, as Figure 1 The inner bottom surface of the casing 4 is gradually arranged obliquely downward toward one side of the fermentation box 9, and a discharge hole 5 is provided at the lowest end of the casing 4. The discharge hole 5 is connected to the feed port of the fermentation box 9 below it through a feed pipe 8. The fallen black tea can slide downward through the bottom of the casing 4, fall into the discharge hole 5, enter the feed pipe 8, and then enter the fermentation box 9 for fermentation.
[0027] As a specific implementation structure, such as Figure 1-2The feed port mentioned above is located at the top of the fermentation box 9. A number of placement plates 15 for placing rolled black tea are arranged in parallel in the fermentation box 9. The placement plates 15 are hollowed out for ventilation. A support column 17 parallel to the width direction is fixed at the bottom center of each placement plate 15. The support column 17 is rotated 90° around the axis of the support column 17 by a driving device. The driving device can be a motor. In addition, the heating power of the heating tube 14 between two adjacent placement plates 15 decreases from top to bottom. The black tea that has just entered can quickly reach the fermentation temperature. Then, as the residence time in the fermentation box 9 increases, the heat accumulated after stacking increases, and the required electric heat tends to decrease. The heating power is gradually reduced, which is also convenient for the black tea to smoothly pass through a temperature change area, obtain a better fermentation effect, and to quickly get out of the oven at a suitable temperature. During specific production, a material receiving chamber may be provided below the bottommost placement plate 15, and this material receiving chamber is located at the inner bottom end of the fermentation box 9. A discharge valve is installed at the bottom of the material receiving chamber, and a drying box (not shown in the figure) is connected to the outlet end of the discharge valve. Therefore, after the discharge valve is opened, the fermented black tea can enter the drying box for drying, so as to be output as the finished product after subsequent screening.
[0028] like Figure 1 As shown, as a specific implementation detail, the front and rear sides of the fermentation box 9 are respectively provided with a spray pipe 10, and a plurality of nozzles 11 are connected to the spray pipe 10. The nozzles 11 spray water mist toward the corresponding black tea to humidify and maintain the corresponding humidity. In addition, an air inlet pipe 12 and an air outlet pipe are respectively provided on the left and right sides of the fermentation box 9. Both pipes are arranged in the box wall along the width direction of the fermentation box 9, and a plurality of air holes are specially provided along the length direction of the pipe on the side surface of the pipe facing the fermentation box 9 for air intake or air outlet. For example, the air inlet pipe 12 can be connected to the inlet end of an air pump to suck away the wet air in the fermentation box 9, and after internal transportation, it reaches the drying device on the air inlet pipe 12, so that the air is dried after flowing through and the humidity is reduced. Similarly, the air outlet pipe is connected to the air outlet end of the air pump to input the dried air into the fermentation box 9 until the humidity position in the fermentation box 9 reaches the target value, and then the pump can be stopped. As for the heating tube 14, the heating tube 14 can be set in the heat-conducting cavity (not shown in the figure) on the inner wall of the fermentation box 9. The heat-conducting cavity is made of heat-conducting material only on the side facing the inner side of the fermentation box 9, and then the inside of the fermentation box 9 is heated. In addition, during the production, a pressure cover (not shown in the figure) is provided inside the tea storage cylinder 6 above the grinding disc 1. The pressure cover is vertically movably installed in the tea storage cylinder 6 and always covers the tea leaves. In essence, it is a circular cover plate vertically slidably installed in the tea storage cylinder 6. Its position in the tea storage cylinder 6 is adjusted by a hydraulic rod or a screw mechanism or a screw, and then different pressures are generated on the black tea, so that it has different degrees of friction with the grinding disc 1, and a better rolling effect is maintained.
[0029] In the above structure, one end of the support column 17 mentioned above can be connected to the main shaft of the motor 16, and the motor 16 is installed behind the fermentation box 9, and except for the placement plate 15 at the bottom, the left and right sides of the other placement plates 15 do not contact the inner wall of the fermentation box 9, so as not to interfere with the rotation of the placement plate 15. As for the placement plate 15 at the bottom, a contact block 25 is fixed on each of its left and right sides. When the placement plate 15 is in a horizontal position, the contact block 25 contacts the slider 26 horizontally elastically installed on the inner wall of the fermentation box 9, which not only maintains the stability of the horizontal position of the placement plate 15 at this time, but also does not prevent its normal rotation, because once it rotates, it will squeeze the slider 26 and slide back, so that the placement plate 15 can rotate smoothly, which is also the reason why the placement plate 15 at the bottom does not need to maintain a sufficiently large gap with the inner wall of the fermentation box 9. When the placement plate 15 is in a horizontal state, the slider 26 is squeezed and thus completely located within the side wall of the fermentation box 9. When the placement plate 15 is in a vertical state, the slider 26 will partially pop out toward the outside of the inner wall of the fermentation box 9, that is, when the side of the slider 26 facing the inner side of the fermentation box 9 is a convex arc surface, this arc surface will never completely slide out of the inner wall of the fermentation box 9, so that the placement plate 15 can contact the arc surface of the slider 26 during the process of rotating to the horizontal position, and be smoothly squeezed back into the side wall of the fermentation box 9.
[0030] In the above structure, specifically, it can be as follows Figure 2 As shown, the inner bottom of the fermentation box 9 is a funnel-shaped cabin structure 18 that is larger at the top and smaller at the bottom. When the bottom placement plate 15 is flipped downward, it does not contact the inner surface of the cabin structure 18 to avoid interference and leave enough storage space for black tea. There is a discharge hole 19 at the bottom end of the cabin structure 18, and a discharge valve is provided on the discharge hole 19 to facilitate the black tea in the cabin structure 18 to fall and be discharged.
[0031] like Figure 2The discharge valve includes a gate plate 20 horizontally and elastically mounted at the bottom of the fermentation box 9. The gate plate 20 has a gate hole 21. One side of the gate plate 20 is elastically and telescopically mounted in a slide groove through a push spring 23. The slide groove is preferably a stepped groove, and an electromagnet 24 is installed near the bottom of the slide groove. When the contact block 25 and the slider 26 are disconnected, that is, when the two are separated, the electromagnet 24 is energized to attract the gate plate 20. As one of the embodiments, that is, when the slider 26 is in contact with the contact block 25, a control circuit is formed so that the control switch of the electromagnet 24 is normally open, and once this control circuit is disconnected, the control switch is closed accordingly, the electromagnet 24 is energized, and the gate plate 20 moves leftward due to the strong magnetic attraction, and then the gate hole 21 is coaxially aligned with the discharge hole 19 to achieve the discharge of tea leaves. On the contrary, when the contact block 25 contacts the slider 26, the electromagnet 24 is de-energized, and the gate plate 20 rebounds to the position in contact with the limit baffle 22 fixed to the outer bottom surface of the fermentation box 9 under the thrust of the push spring 23. At this time, the gate hole 21 is completely offset from the discharge hole 19, and the bottom of the fermentation box 9 is closed.
[0032] like Figure 3 As shown, the end of the slider 26 away from its arc surface is coaxially connected to a first cylindrical spring 29, and the first cylindrical spring 29 is connected to the bottom of the mounting groove of the inner wall of the fermentation box 9. A first mounting column 28 is horizontally fixed in the center of the bottom of the mounting groove. The first mounting column 28 is located in the axial direction of the first cylindrical spring 29, and is fixed with a fixed block 27 that can fit and contact the slider 26. When the contact block 25 contacts and squeezes the slider 26, the slider 26 fits with the fixed block 27. At this time, the two conductors of the slider 26 and the fixed block 27 are energized, as in the previous principle, so that the electromagnet 24 is in a power-off state.
[0033] In addition to Figure 4 The structural principle shown in FIG. Figure 4 The structure shown is made according to the principle of the following structure: that is, the end of the slider 26 that is away from its arc surface is coaxially connected to a second cylindrical spring 32, and the second cylindrical spring 32 is connected to the bottom of a mounting groove on the inner wall of the fermentation box 9, and a second mounting column 31 is horizontally slidably installed in the center of the bottom of the mounting groove. During use, when the contact block 25 is separated from the slider 26, the arc surface portion of the slider 26 pops out of the mounting groove, so that the conductive node 34 on the second mounting column 31 is coaxially in contact with the conductive ring 33 fixedly installed on the outer wall of the fermentation box 9, so that the electromagnet 24 is energized. This is equivalent to closing a control circuit after the contact block 25 is separated from the slider 26. The connection of the control circuit serves as the power circuit of the electromagnet 24, so that the electromagnet 24 is energized. This is exactly the opposite of the aforementioned control circuit connection serving as the normally open power circuit of the electromagnet 24, belonging to two control modes.
[0034] It should be explained here that, in this specification, terms such as first and second are only used to distinguish one feature from another, and do not mean that there is a certain relationship or order between these technical features. The terms "including" and "comprising" refer to the inclusion of one or some technical means or features, specifically meaning that there are other existing or non-existing technical features that have not been included. The discussion in the above embodiments is only a representative example for the present invention, and is by no means the only restrictive constraint feature. A person of ordinary skill in the art should understand that, without departing from the technical content recorded in all the claims of this application, some simple substitutions and modifications can be made, thereby changing or becoming equivalent to other specific embodiments and application scenarios. However, no matter how the adaptability is changed, these embodiments will inevitably fall within the scope of protection of the present invention.
