[0002] Due to its elegant flavor and rich nutrition, enzyme vegetables are deeply favored by people and are becoming an indispensable seasoning side dish in people's daily life. Enzyme vegetables are usually made by lactic acid bacteria. During the production process, the enzyme vegetable materials need to be placed in a closed fermentation tank isolated from air for fermentation.

[0003] The existing fermentation tanks for fermented vegetables are basically traditional fermentation tanks. During fermentation, the gas generated inside the fermentation tank is difficult to be discharged to the outside effectively and quickly. Excessive internal air pressure may cause the fermentation tank to deform and deteriorate the sealing performance. In severe cases, it may cause the fermentation tank to explode and cause harm to personnel. For general exhaust devices on fermentation equipment, after exhausting the internal gas, the closing speed is slow and the sealing is not timely. External air will enter the fermentation tank and cause bacteria to grow in the fermented vegetables, affecting the fermentation effect. Utility Model Content

[0021] Figure 2 It is a three-dimensional structural schematic diagram of a tank body in an embodiment of the utility model.

[0022] like Figure 1 and Figure 2 As shown, the tank body 10 includes a cylindrical body 10a and a hemispherical shell 10b arranged up and down, and four supporting legs 10c.

[0023] The inner spaces of the cylindrical body 10a and the hemispherical shell 10b respectively form a fermentation chamber 11 and a liquid storage chamber 12 which are interconnected.

[0024] The upper opening of the cylindrical body 10a is used as an inlet and outlet 11a for conveying a basket (not shown in the figure) containing enzyme vegetable materials into and out of the fermentation chamber 11. The edge of the inlet and outlet 11a is provided with an upwardly open annular liquid storage tank 11b. The bottom of the annular liquid storage tank 11b is provided with an inlet 11c, and the side is provided with an overflow port 11d. In this embodiment, the inlet 11c is connected and communicated with an external water tank (not shown in the figure) through a liquid supply pipe 10d. The liquid supply pipe 10d is provided with a liquid pump 10e for conveying water in the external water tank to the annular liquid storage tank 11b as a sealing liquid; the overflow port 11d is connected and communicated with the external water tank through a return liquid pipe (not shown in the figure) for returning excess sealing liquid in the annular liquid storage tank 11b to the external water tank.

[0025] A drain port 12a is provided at the central portion of the bottom of the hemispherical shell 10b, and a valve 12b is provided on the drain port 12a.

[0026] Four support legs 10c are evenly spaced along the circumference of the cylinder 10a to support the cylinder 10 and the hemispherical shell 10b. In this embodiment, the upper end of each support leg 10 is fixedly connected to the outer wall of the lower end of the cylinder 10a.

[0027] Figure 3 It is a three-dimensional structural schematic diagram of a tank cover in an embodiment of the utility model.

[0028] like Figure 1 and Figure 3 As shown, the can cover 20 is installed at the inlet and outlet 11a of the can body 10 to open or close the inlet and outlet 11a. The can cover 20 includes a cover body 21, a cover ring 22 and an annular dust cover 23.

[0029] The cover 21 is an upwardly convex spherical arc-shaped body, which is installed above the can body 10 through a cover flip mechanism 21a. Under the drive of the cover flip mechanism 21a, it can flip up and down relative to the can body 10, thereby opening or closing the inlet and outlet 11a. The cover flip mechanism 21a is fixedly connected to the top of the side wall of the cylinder 10b. The cover flip structure 21a is a prior art and will not be described in detail here.

[0030] In this embodiment, two observation mirrors 21 b are provided on the cover body 21 , and a lighting lamp (not shown in the figure) is installed at one of the observation mirrors 21 b to facilitate clear observation of the situation inside the tank body 10 .

[0031] The cover ring 22 extends downward from the outer edge of the cover body 21 and matches the annular liquid storage groove 11b. When the cover body flipping mechanism 21a drives the cover body 21 to flip downward, the cover ring 22 is embedded in the annular liquid storage groove 11b and the lower surface of the cover ring 22 can fit with the inner bottom wall of the annular liquid storage groove 22.

[0032] The lower surface of the cover ring 22 is provided with a plurality of connecting grooves 22a, which are arranged at equal intervals along the circumference of the cover ring 22, and are used to connect the inner and outer sides of the cover ring 22 when the lower surface of the cover ring 22 is in contact with the inner bottom wall of the annular liquid storage tank 22, thereby connecting the liquid inside and outside the annular liquid storage tank 22 to play a sealing role; moreover, during the fermentation process, the gas inside the tank body 10 due to the fermentation of enzyme vegetable materials, whose air pressure is greater than the external air pressure, is smoothly released to the outside of the tank body 10 through the gap between the connecting grooves 22a and the annular liquid storage tank 22.

[0033] In this embodiment, the overflow port 11 d is located above the groove 22 a , so that the liquid level of the sealing liquid in the annular liquid storage tank 22 is higher than the groove 22 a , thereby ensuring the sealing effect and preventing the outside air from entering the tank body 10 .

[0034] The annular dust cover 23 is used to prevent dust from falling into the annular liquid storage tank 11b, and has an annular cover body 23a and a flange 23b.

[0035] The annular cover 23a is formed on the outer edge of the cover 21 and is a circular plate having an outer diameter greater than that of the annular liquid storage tank 11b. In this embodiment, an observation mirror 23c is provided on the annular cover 23a to facilitate visual observation of the sealing liquid in the annular liquid storage tank 11b.

[0036] The flange 23b is folded downward from the outer edge of the annular cover body 23a.

[0037] The control unit includes a liquid level sensor and a microprocessor.

[0038] The liquid level sensor is arranged on the side wall of the annular liquid storage tank 11b at a height position between the connecting groove 22a and the overflow port 11d, and is used to monitor the liquid level in the annular liquid storage tank 11b in real time, and generate a liquid level signal when the liquid level is lower than a preset liquid level value and send the liquid level signal to the microprocessor.

[0039] The microprocessor is connected to the liquid level sensor, the liquid pump 10e and the cover flipping mechanism 21a respectively, and is used to control the operation of the liquid pump 10e to transport the sealing liquid to the annular liquid storage tank 11b according to the liquid level signal sent by the liquid level sensor; it is also used to control the operation of the cover flipping mechanism 21a to drive the cover 21 to flip upward or downward, so that the tank cover 20 opens or closes the inlet and outlet 11a.

[0040] Functions and Effects of the Embodiments

[0041] According to the sealing structure of the enzyme vegetable fermentation tank involved in the present embodiment, since an upwardly open annular liquid storage tank is provided at the edge of the inlet and outlet of the tank body, the lower surface of the cover ring of the tank lid can fit with the inner bottom wall of the annular liquid storage tank and is provided with a plurality of connecting grooves arranged at intervals along the circumference of the cover ring, which can make the inner and outer sides of the cover ring connected. When the air pressure in the tank body is greater than the external air pressure, the gas in the tank body will be quickly and smoothly discharged to the outside through the gap between the connecting groove and the inner bottom wall of the annular liquid storage tank. Once the internal and external air pressures are balanced, the sealing liquid in the annular liquid storage tank plays a sealing role, effectively preventing external air from entering the fermentation tank, thereby ensuring the fermentation effect.

[0042] In addition, because there is also a liquid pump, a liquid inlet is provided at the bottom of the annular liquid storage tank, an overflow port is provided at the side above the groove, the liquid inlet is connected to the external water tank through a liquid supply pipe, a liquid pump is provided on the liquid supply pipe, and the overflow port is connected to the external water tank through a liquid return pipe, which can conveniently transport sealing liquid to the annular liquid storage tank and allow excess liquid in the annular liquid storage tank to flow back to the external water tank.

[0043] Furthermore, because it also has a liquid level sensor and a microprocessor, the liquid level sensor is arranged on the side wall of the annular liquid storage tank, and can monitor the liquid level of the liquid in the annular liquid storage tank in real time. When the liquid level is lower than the preset liquid level value, a liquid level signal is generated and the liquid level signal is sent to the microprocessor. The microprocessor controls the operation of the liquid pump according to the liquid level signal to transport the sealing liquid to the annular liquid storage tank, thereby realizing automatic liquid replenishment.

[0044] In addition, because the tank cover also includes an annular dust cover formed on the outer edge of the cover body, dust can be effectively prevented from falling into the annular liquid storage tank.

[0045] The above implementation modes are preferred examples of the present invention and are not intended to limit the protection scope of the present invention.
