[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a black tea fermentation device for easy collection of fermentation liquid includes a fermentation tank body 1, a steam generator 2, and an oxygen delivery device 3. The fermentation tank body 1 contains several fermentation trays 11, and a collection chamber 12 is located at the lower part of the fermentation tank body 1. One side of the collection chamber 12 is open, and a collection container 13 is located inside. The upper end of the collection container 13 is open, and a first filter screen 14 and a second filter screen 15 are arranged from top to bottom along the height direction inside. The first filter screen 14 and the second filter screen 15 are fixed inside the collection container 13 by mounting steps 16. A collection port 17 is provided on the side wall of the collection container 13, and the collection port 17 communicates with the interior of the collection container 13. Several coarse filter screens are provided on the surface of the first filter screen 14, and several fine filter screens are provided on the surface of the second filter screen 15. The pore size of the coarse filter screen is larger than that of the fine filter screen.
[0024] The collection container 13 has a drawer-type design and can be installed into the fermentation box from the opening side of the collection chamber 12. The collection container 13 can be disassembled and assembled without opening the main body of the fermentation box 1, minimizing the impact on the fermentation process. The fermentation liquid produced during the fermentation of black tea drips naturally and is collected in the collection container 13 after being filtered by the first filter screen 14 and the second filter screen 15, which facilitates further processing. The first filter screen 14 has a larger pore size to filter larger impurities and is less prone to clogging, while the second filter screen 15 has a smaller pore size to filter finer impurities, ensuring that the collected fermentation liquid is relatively clean.
[0025] The steam generator 2 and the oxygen delivery device 3 are respectively connected to the interior of the fermentation chamber body 1. The interior of the fermentation chamber is divided into several relatively independent spaces by the fermentation tray 11. Therefore, the steam generator 2 needs to be connected to each of these independent spaces to ensure the fermentation effect. In addition, in order to ensure that the air inside the fermentation chamber can circulate in a timely manner, an exhaust fan 18 is also installed on the side wall of the fermentation chamber body 1 to assist in ventilation in conjunction with the oxygen delivery device 3, ensuring sufficient oxygen inside so that the tea can ferment fully. The steam generator 2 and the oxygen delivery device 3 are both existing technologies and will not be described in detail here.
[0026] In practical applications, the installation steps 16 include a first step 161 and a second step 162; the number of installation steps 16 is two; the distance between the two first steps 161 is greater than the distance between the two second steps 162. In use, the first filter screen 14 is placed between the two first steps 161, and the second filter screen 15 is placed between the two second steps 162. Due to the different sizes, the problem of different filter screen installation order is avoided in actual use.
[0027] A shut-off valve 171 is provided at the collection port 17. The fermentation broth can be stored in the collection container 13 or transferred to other containers for further processing through the collection port 17 and the shut-off valve 171.
[0028] The bottom of the fermentation tray 11 is provided with several ventilation holes 111 to facilitate air circulation; in order to avoid tea leaves clogging the ventilation holes 111 as much as possible, a mesh cloth is also laid on top of the fermentation tray 11.
[0029] Several sets of mounting rails 112 are provided on the inner wall of the fermentation box body 1; the fermentation tray 11 can be quickly and stably fixed inside the fermentation box body 1 through the mounting rails 112.

The upper end of the collection container 13 is open, and a first filter screen 14 and a second filter screen 15 are arranged from top to bottom along the height direction inside. The first filter screen 14 and the second filter screen 15 are fixed inside the collection container 13 by mounting steps 16. A collection port 17 is provided on the side wall of the collection container 13, and the collection port 17 communicates with the interior of the collection container 13. Several coarse filter screens are provided on the surface of the first filter screen 14, and several fine filter screens are provided on the surface of the second filter screen 15. The pore size of the coarse filter screen is larger than that of the fine filter screen.
[0032] The collection container 13 has a drawer-type design and can be installed into the fermentation box from the opening side of the collection chamber 12. The collection container 13 can be disassembled and assembled without opening the main body of the fermentation box 1, minimizing the impact on the fermentation process. The fermentation liquid produced during the fermentation of black tea drips naturally and is collected in the collection container 13 after being filtered by the first filter screen 14 and the second filter screen 15, which facilitates further processing. The first filter screen 14 has a larger pore size to filter larger impurities and is less prone to clogging, while the second filter screen 15 has a smaller pore size to filter finer impurities, ensuring that the collected fermentation liquid is relatively clean.

Due to the different sizes, the problem of different filter screen installation order is avoided in actual use.
[0035] To ensure overall airtightness, a sealing block 121 is provided at the opening of the collection chamber 12. The sealing block 121 is "L" shaped and can prevent foreign objects from entering the interior. Correspondingly, a sealing strip 132 is provided on the upper edge of the collection container 13 to further enhance the sealing effect.
[0036] A shut-off valve 171 is provided at the collection port 17. The fermentation broth can be stored in the collection container 13 or transferred to other containers for further processing through the collection port 17 and the shut-off valve 171.
[0037] The collection container 13 is provided with a handle 131 and a transparent observation window on the outside. The handle 131 can be used to easily pull the collection container 13 out of the fermentation box, while the transparent observation window makes it easy to observe the collection of the fermentation liquid inside.
[0038] The bottom of the fermentation tray 11 is provided with several ventilation holes 111 to facilitate air circulation; in order to avoid tea leaves clogging the ventilation holes 111 as much as possible, a mesh cloth is also laid on top of the fermentation tray 11.
