[0026] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0027] The present application embodiment discloses a black tea fermentation temperature and humidity controller. Figure 1 and Figure 2A black tea fermentation temperature and humidity control machine includes a box body 1, a heating device 11 and a humidifying device 12, wherein the heating device 11 and the humidifying device 12 are conventional settings in the prior art, and only need to be able to input hot air and humidifying water mist into the box body 1, and the specific structure is not repeated here. The present application also includes a plurality of fermentation boxes 2 arranged in sequence from top to bottom, a plurality of clamping strips 3 are arranged in the box body 1, two clamping strips 3 are set and are used to clamp a fermentation box 2, the top and bottom of the fermentation box 2 are open, and the open part of the bottom of the fermentation box 2 is provided with a soft breathable member 21 with a width larger than the open area, and the soft breathable member 21 can be made of gauze, cotton cloth, nylon mesh and other materials with good flexibility, air permeability and certain temperature resistance.
[0028] In addition, a scraper 4 is provided below the fermentation box 2 in the box body 1. The scraper 4 is provided along the depth direction of the box door of the box body 1. The top of the scraper 4 pushes the soft breathable member 21 and extends into the fermentation box 2. A driving mechanism is provided in the box body 1 to drive the scraper 4 to reciprocate in the fermentation box 2.
[0029] After the arrangement is made in this way, after the black tea to be fermented is placed in the fermentation box 2, the fermentation box 2 is loaded into the box body 1 and clamped by two corresponding clamping strips 3. At this time, the scraper 4 pushes upward against the soft breathable member 21 at the bottom of the fermentation box 2, so that a part of the soft breathable member 21 protrudes from the upper end surface of the inner bottom wall of the fermentation box 2, and a part of the black tea in the fermentation box 2 can be lifted up; subsequently, in the process of the heating device 11 and the humidifying device 12 controlling the temperature and humidity in the box body 1, the scraper 4 is driven by the driving mechanism. The reciprocating motion in the fermentation box 2 can make the raised part of the soft breathable member 21 move back and forth, so that the black tea in the fermentation box 2 can be lifted up and slid down in turn, so as to achieve the turning effect of the black tea in the fermentation box 2. During this process, the scraper 4 does not directly contact the black tea, which reduces the probability of damaging the integrity of the black tea. The scraper 4 pushes the soft breathable member 21 to turn the black tea starting from the bottom layer. Therefore, the black tea in the fermentation box 2 can be turned more comprehensively, which helps to improve the fermentation efficiency and fermentation quality of the black tea.
[0030] Specifically, refer to Figure 1 The driving mechanism includes a winding roller 51 and an unwinding roller 52 rotatably installed in the box body 1 and a servo motor for driving the two to rotate forward and reversely. The winding roller 51 and the unwinding roller 52 are parallel to each other and each corresponds to a servo motor. A conveying chain 53 is wound around the winding roller 51 and the unwinding roller 52. The conveying chain 53 is serpentine and sequentially wrapped around the bottom ends of multiple fermentation boxes 2. The scraper 4 is fixed to the conveying chain 53; specifically, a plurality of guide rollers 55 are rotatably installed in the box body 1, and the guide rollers 55 are arranged parallel to the winding roller 51 and the unwinding roller 52. The conveying chain 53 is arranged in a serpentine shape in the box body 1 through the plurality of guide rollers 55. The guide rollers 55 are arranged directly opposite to the box door of the box body 1, so that the fermentation box 2 can be conveniently taken and placed at the box door of the box body 1.
[0031] When the conveyor chain 53 is in operation, the two scrapers 4 adjacent to each other move in opposite directions; and in the initial state, the two scrapers 4 adjacent to each other are arranged at two opposite sides of the fermentation box 2, specifically at two sides of the door side of the box body 1. In addition, the conveyor chain 53 is provided with two ends of the scraper 4 in the length direction, and the two ends of the scraper 4 are respectively fixed to the two conveyor chains 53 to improve the stability of the scraper 4 when following the conveyor chain 53 to ensure the turning effect of the black tea on the soft breathable member 21.
[0032] In this way, when the two servo motors drive the winding roller 51 and the unwinding roller 52 to rotate respectively, the winding roller 51 winds up the conveyor chain 53 and the unwinding roller 52 unwinds the conveyor chain 53, and the multiple guide rollers 55 guide the conveyor chain 53 in a serpentine manner. Therefore, the conveyor chain 53 can simultaneously drive the multiple scrapers 4 to move under the fermentation box 2 during operation. Although the two scrapers 4 on the two adjacent fermentation boxes 2 move in opposite directions, the turning effect on the black tea in the fermentation box 2 is the same; when the scraper 4 moves to the other side of the fermentation box 2, the two servo motors drive the winding roller 51 and the unwinding roller 52 to rotate in the opposite direction respectively. At this time, the winding roller 51 unwinds the conveyor chain 53 and the unwinding roller 52 winds up the conveyor chain 53, so that the multiple scrapers 4 move in the opposite direction at the same time. Therefore, the multiple scrapers 4 can be reciprocated in the fermentation box 2, so as to turn the black tea in the fermentation box 2 more comprehensively.
[0033] At the same time, in order to prevent the part of the soft breathable member 21 that is not pushed by the scraper 4 from sagging under the weight of the black tea and causing the black tea to be concentrated in one place of the soft breathable member 21, refer to Figure 1 and Figure 2 A plurality of spaced support bars 54 are connected between the two conveyor chains 53. The support bars 54 are arranged parallel to the scraper 4. The plurality of support bars 54 are arranged along the length direction of the conveyor chain 53, and the upper and lower end surfaces of the support bars 54 protrude from the upper and lower end surfaces of the conveyor chain 53, so that at least one side of the upper and lower end surfaces of the support bars 54 can support the soft breathable member 21 when the conveyor chain 53 moves.
[0034] In this way, when the scraper 4 moves back and forth at the bottom of the fermentation box 2, the multiple support bars 54 between the two conveyor chains 53 can provide more comprehensive support for the soft breathable component 21, which can effectively improve the sagging phenomenon of the soft breathable component 21, so as to ensure that the black tea in the fermentation box 2 can be spread out as flat as possible, and ensure the temperature and humidity control effects of the heating device 11 and the humidifying device 12 on the black tea.
[0035] Furthermore, in order to further enhance the convenience of this application in practical applications, refer to Figure 1A card slot 31 is provided along the length direction of the card strip 3 on the side close to the fermentation box 2, and a card block 22 slidably adapted to the card slot 31 is fixedly connected to the side of the fermentation box 2. Both ends of the card strip 3 are respectively fixedly connected to the inner walls at both ends of the box door of the box body 1 in the depth direction to avoid interfering with the operation of the conveyor chain 53; and a handle (not shown in the figure) is provided on the side of the fermentation box 2 close to the box door of the box body 1, so that the fermentation box 2 can be easily pulled out after fermentation is completed.
[0036] In this way, the worker can push the fermentation box 2 into the box body 1 smoothly with the help of the sliding connection between the block 22 on the side of the fermentation box 2 and the slot 31 on the card strip 3. When the card strip 3 supports the fermentation box 2, it can also limit the displacement of the fermentation box 2 in the vertical direction to ensure the effect of the scraper 4 when pushing and scraping the soft breathable part 21; and after the card strip 3 is set on the side wall of the fermentation box 2, the conveying chain 53 can be set as close to the lower end surface of the fermentation box 2 as possible, thereby ensuring the supporting effect of the support strip 54 on the soft breathable part 21.
[0037] The implementation principle of a black tea fermentation temperature and humidity controller in the present application embodiment is as follows:
[0038] After the fermentation box 2 is filled with the black tea to be fermented, the fermentation box 2 is loaded into the box body 1 and clamped by the clamping strip 3, and then by driving the winding roller 51 and the unwinding roller 52 to rotate in the same direction forward and reverse, the conveying chain 53 can be driven to drive the scraper 4 to reciprocate in the fermentation box 2, so that the scraper 4 can push the raised part formed by the soft breathable member 21 to move back and forth in the fermentation box 2, so that the black tea in the fermentation box 2 can be lifted up and slid down in turn, so as to achieve the turning effect of the black tea in the fermentation box 2; and in this process, the scraper 4 does not directly contact the black tea, reducing the probability of damaging the integrity of the black tea, and the scraper 4 pushes the soft breathable member 21 to turn the black tea starting from the bottom layer, so the black tea in the fermentation box 2 can be turned more comprehensively, which is helpful to improve the fermentation efficiency and fermentation quality of the black tea.
