DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] Embodiment 1
[0024] A tea fermentation device facilitating pile turning, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , comprising a tank body 1, the tank body 1 is provided with a feed inlet 2 on the top wall, a discharge outlet 3 is provided below one side wall of the tank body 1, and a discharge door 4 is arranged at the discharge outlet 3 of the tank body 1; a motor 5 is arranged on the top wall of the tank body 1, a stirring shaft 6 is rotatably arranged on the top wall of the tank body 1, one end of the stirring shaft 6 is located outside the tank body 1 and connected with the output shaft of the motor 5, the other end of the stirring shaft 6 extends into the tank body 1, and a plurality of stirring blades 7 are arranged at intervals along the length direction of the stirring shaft 6 at the end of the stirring shaft 6 located inside the tank body 1; a vertical rod 8 is arranged on the top wall of the tank body 1, the lower end of the vertical rod 8 extends into the tank body 1 and is connected with a mounting rod 9, the vertical rod 8 is located outside the rotating circumferential track of the end of the stirring blade 7 away from the stirring shaft 6, and the end of the mounting rod 9 away from the vertical rod 8 extends between two adjacent stirring blades 7, and the end of the mounting rod 9 close to the stirring shaft 6 is provided with a temperature sensor 10.
[0025] In the scheme, when the tea is fermented, the tea is added to the inside of the tank body 1 through the feeding port 2, and the fermentation can be started. Since the temperature sensor 10 is close to the stirring shaft 6, the temperature of the center of the tea pile in the fermentation process is detected by the temperature sensor 10. The temperature data of the center of the tea pile can be displayed on the display screen (not shown in the figure). The display screen is electrically connected with the temperature sensor 10. The display screen can be arranged on the tank body 1. The connection mode between the display screen and the temperature sensor 10 is known in the art, and thus will not be described here. The staff can directly observe the temperature of the center of the tea pile. When the temperature of the center of the tea pile is high, the motor 5 is started. The motor 5 can drive the stirring shaft 6 and the stirring blade 7 to stir the tea pile, so as to facilitate the stirring and turning of the tea pile, and also facilitate the scattering of the tea which is knotted into a group. Moreover, since the temperature sensor 10 is located between the upper and lower two adjacent stirring blades 7, the stirring blade 7 will not touch the vertical rod 8, the mounting rod 9 and the temperature sensor 10 during the rotation of the stirring shaft 6.
[0026] Example 2
[0027] In this embodiment, on the basis of example 1, referring to Figure 1 , Figure 2 , the top wall of the tank body 1 is provided with a fixing cylinder 11. The vertical rod 8 is arranged in the inside of the fixing cylinder 11. The upper end of the vertical rod 8 extends above the fixing cylinder 11 and is provided with a handle 12. Threaded holes are formed in the fixing cylinder 11. The fixing bolts 13 are threadedly connected in the threaded holes. The rod portions of the fixing bolts 13 pass through the threaded holes and abut against the outer wall of the vertical rod 8.
[0028] In the scheme, since the depth of the tea pile in the tank body 1 is different, the center position of the tea pile is also different. At this time, the position of the temperature sensor 10 can be adjusted according to the height of the tea pile. The specific method for adjusting the position of the temperature sensor 10 is as follows: one hand holds the handle 12, and the other hand loosens the fixing bolts 13. Then the height of the vertical rod 8 is adjusted through the handle 12, so as to adjust the height of the temperature sensor 10. It should be noted that in the scheme, the starting mode of the motor 5 can be point control. The characteristic of the point control mode of the motor 5 is that the motor 5 starts to operate when the control button is pressed. Once the button is released, the motor 5 stops immediately. This control mode is especially suitable for occasions where the motor 5 needs to operate for a short time. The operator can accurately control the starting and stopping of the motor 5. In this way, the position of the stirring blade 7 can be adjusted, and the temperature sensor 10 can be adjusted to another upper and lower two adjacent stirring blades 7. The higher the height of the tank body 1, the higher the height of the tea pile that can be stacked in the tank body 1. The higher the height difference of the center position of the tea pile at different heights.
[0029] Example 3
[0030] On the basis of embodiment 2, in this embodiment, referring to Figure 1 、 Figure 3 , the vertical rod 8 and the fixed cylinder 11 are in sliding fit, which is beneficial to reduce the gap between the vertical rod 8 and the fixed cylinder 11, the feeding pipe 20 is communicated at the feeding port 2 of the tank body 1, the outer wall of the feeding pipe 20 is provided with external threads, and the feeding cover 14 is threadedly connected to the feeding pipe 20; during the fermentation of the tea leaves, the feeding port 2 is closed through the feeding cover 14, so that the sealing performance of the tank body 1 is improved. The sealing ring can also be arranged in the fixed cylinder 11, and the vertical rod 8 is located in the inner ring of the sealing ring and in sliding sealing fit with the sealing ring, so as to facilitate the use for the tea leaves that need to be sealed for fermentation, such as the fermentation of black tea and Pu'er tea.
[0031] In the early stage of fermentation, the sealing of the tank body 1 can help the tea leaves to be quickly heated, accelerate the activity of enzymes, and promote the oxidation of polyphenols in the tea leaves to form the unique aroma and color of black tea. In the later stage of fermentation, the sealing can help to maintain the aroma of the tea leaves and prevent the aroma from being excessively volatilized.
[0032] Embodiment 4

[0034] In this scheme, by arranging the guide strip 16 and the guide groove 15 in sliding fit, the vertical rod 8 can be lifted and lowered along the length direction of the guide groove 15, so that the mounting rod 9 does not rotate during the lifting and lowering of the vertical rod 8, that is, the temperature sensor 10 is always close to the stirring shaft 6, so that the temperature sensor 10 can detect the temperature of the central part of the tea leaf pile.
[0035] Embodiment 5
[0036] On the basis of embodiment 1, in this embodiment, referring to Figure 1 、 Figure 3 , the vent pipe 17 is arranged on the top wall of the tank body 1, and the plug 18 is detachably arranged on the vent pipe 17. The plug 18 is a rubber plug, which can plug the air inlet end of the vent pipe 17 to block the vent pipe 17.
[0037] In this scheme, during the turning of the tea leaf pile, the plug 18 can be opened, which can increase the oxygen concentration in the tank body 1, discharge excessive moisture in the tank body 1, and also reduce the temperature in the tank body 1.
[0038] Embodiment 6
[0039] In this embodiment, on the basis of embodiment 2, referring to Figure 1 , the sidewall of the tank body 1 is provided with a visual window 19, and the rod segment of the vertical rod 8 located inside the tank body 1 is close to the visual window 19; the visual window 19 is made of glass or transparent plastic material, and the height of the temperature sensor 10 and the position of the center of the tea leaf pile can be viewed through the visual window 19; when adjusting the height of the temperature sensor 10, only the position of the lower end of the vertical rod 8 is needed to find the position of the temperature sensor 10, and then the temperature sensor 10 can be adjusted to the position close to the center of the tea leaf pile.
