DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1-5 The present invention provides a lactic acid bacteria juice beverage fermentation device, comprising:

[0028] The fermentation tank comprises an upper tank body 1 and a lower tank body 2, the upper tank body 1 and the lower tank body 2 are fixedly connected, a first partition 3 and a second partition 4 are fixedly connected inside the upper tank body 1, a rotating shaft 5 is rotatably connected to the upper tank body 1, the rotating shaft 5 passes through the first partition 3 and the second partition 4, an electric telescopic rod 47 is arranged on the rotating shaft 5, a stirring frame 6 is slidably connected inside the lower tank body 2, the electric telescopic rod 47 is transmission-connected to the stirring frame 6, an electromagnet 7 is fixedly connected to the stirring frame 6, a motor 8 is fixedly connected outside the upper tank body 1, the motor 8 is transmission-connected to the rotating shaft 5, a liquid filling port and a liquid discharge port are opened on the lower tank body 2, a first valve 9 is arranged on the liquid discharge port, and a second valve 10 is installed on the liquid filling port;

[0029] The sampling assembly includes a plurality of hoses 11, the hoses 11 are wound around a retractable mechanism, the retractable mechanism is fixedly connected to the second partition 4, the ends of the hoses 11 pass through the second partition 4, the ends of the hoses 11 are connected to a pipe head 12, an electromagnet 13 is fixedly connected to the pipe head 12, a first connecting pipe 14 connected to the hose 11 is provided on the retractable mechanism, the first connecting pipe 14 is connected to a vacuum mechanism, the vacuum mechanism is connected to a drain pipe 15 and a ventilation mechanism, the drain pipe 15 extends out of the upper tank body 1, and a third valve 16 is installed on the drain pipe 15.

[0030] In the present device, the fermentation tank is used for fermenting lactic acid bacteria juice beverages. Raw materials are added to the fermentation tank through the liquid filling port. The motor 8 drives the rotating shaft 5 to rotate, and the electric telescopic rod 43 can drive the stirring frame 6 to move up and down, so that the fermentation liquid in the lower tank body 2 can be stirred. The retractable mechanism is used to reel in the hose 11, and the tube head 12 is convenient for sucking in the fermentation liquid. The vacuum mechanism can suck in the fermentation liquid. The electromagnet 1 7 and the electromagnet 2 13 are correspondingly arranged. When it is necessary to sample the fermentation liquid, the stirring frame 6 moves up, and the electromagnet 1 7 and the electromagnet 2 13 are energized, so that the electromagnet 2 13 and the electromagnet 1 7 are close to each other and adsorbed together. The stirring frame 6 moves down, and the electromagnet 2 13 and the tube head 12 move down until they enter the fermentation liquid. When sampling, the stirring frame 6 slowly enters into the fermentation liquid to prevent the fermentation liquid from being violently stirred. When the tube head 12 enters the fermentation liquid with the stirring frame 6, the fermentation liquid can be sucked in by the vacuum mechanism. The ventilation mechanism is turned on to discharge the fermentation liquid through the discharge pipe 15. After the sampling is completed, the electromagnet 1 7 and the electromagnet 2 13 are powered off, so that the hose 11 can be retracted to the retracting mechanism. The hose 11 has multiple tube heads 12, and the stirring frame 6 can drive the multiple tube heads 12 to enter the fermentation liquid. At the same time, the motor 8 can drive the rotating shaft 5 to rotate, so that the stirring frame 6 can rotate, and the position of the tube head 12 in the fermentation liquid can be adjusted. Therefore, sampling at multiple positions can be achieved, or the depth of the fermentation liquid can be adjusted, and fermentation liquids of different depths can be sampled through multiple tube heads 12.

[0031] A further optimized solution is provided, in which the vacuum mechanism includes a transfer box 17 and a vacuum pump 18. The vacuum pump 18 and the transfer box 17 are fixedly connected to the first partition plate 3. The vacuum pump 18 and the transfer box 17 are connected via a second connecting pipe 19. The vacuum pump 18 is used to evacuate the transfer box 17. A first solenoid valve 20 is installed on the first connecting pipe 14, a second solenoid valve 21 is installed on the second connecting pipe 19, and a fifth connecting pipe 22 is connected to the exhaust port of the vacuum pump 18. The fifth connecting pipe 22 extends out of the upper tank body 1.

[0032] The vacuum pump 18 is used to evacuate the transfer box 17. When the pipe head 12 enters the fermentation liquid, the vacuum pump 18 is started to evacuate the transfer box 17 through the second connecting pipe 19, so that the fermentation liquid enters the transfer box 17 through the hose 11 and the first connecting pipe 14. When the fermentation liquid in the transfer box 17 reaches a certain amount, the vacuum pump 18 is turned off, and the first solenoid valve 20 and the second solenoid valve 21 are closed at the same time to prevent the transfer box 17 from leaking. The ventilation mechanism is opened to allow the fermentation liquid in the transfer box 17 to flow out. The fermentation liquid flows out through the drain pipe 15, and the third valve 16 can control the drain pipe 15.

[0033] According to a further optimization scheme, the ventilation mechanism includes an air filter 23, which is connected to the transfer box 17 through a third connecting pipe 24, on which a third solenoid valve 25 is installed, and the air filter 23 is connected to a fourth connecting pipe 26, which extends out of the upper tank body 1.

[0034] The air filter 23 is used to filter the air. When the first solenoid valve 20 and the second solenoid valve 21 are closed, the third solenoid valve 25 is opened, and the external air enters the transfer box 17 after being filtered by the air filter 23. The air pressure in the transfer box 17 is balanced with the outside, thereby facilitating the outflow of the fermentation liquid.

[0035] A further optimized solution is that an air pump 27 is fixedly connected to the first partition 3, a first air pipe 29 is connected to the first connecting pipe 14, the first air pipe 29 is connected to the air outlet of the air pump 27, a second air pipe 28 is connected to the air inlet of the air pump 27, the second air pipe 28 passes through the first partition 3 and the second partition 4 and extends into the lower tank body 2, and a fourth solenoid valve 30 is installed on the first air pipe 29.

[0036] When the first solenoid valve 20 is closed, fermentation liquid will remain in the first connecting pipe 14 and the hose 11. At this time, the fourth solenoid valve 30 is opened and the air pump 27 is started. The air pump 27 blows the gas in the lower tank body 2 into the first connecting pipe 14 and the hose 11, thereby preventing the fermentation liquid from remaining in the first connecting pipe 14 and the hose 11.

[0037] A further optimized solution is that a water pump 31 is fixedly connected to the first partition 3, the water pump 31 is connected to a water source, the water outlet of the water pump 31 is connected to a main pipe, the main pipe is connected to a plurality of water branch pipes 32, the water branch pipes 32 are connected to the transfer box 17, and a fifth solenoid valve 33 is installed on the water branch pipe 32.

[0038] When all the fermentation liquid samples in the transfer box 17 are discharged, in order to avoid the residual fermentation liquid in the transfer box 17 affecting the next time, the transfer box and the discharge pipe 15 can be cleaned by the water pump 31. During cleaning, the third valve 16 is opened, and the first solenoid valve 20, the second solenoid valve 21, the third solenoid valve 25 and the fourth solenoid valve 30 are closed, so that the cleaned liquid can be directly discharged from the transfer box 17.

[0039] A further optimized solution is that the retracting and releasing mechanism includes a reel 34, two support plates 35 are fixedly connected to the second partition plate 4, a center shaft 36 is fixedly connected to the reel 34, the center shaft 36 is rotatably connected to the support plate 35, a coil spring is installed between the center shaft 36 and the support plate 35, a channel 37 is opened on the center shaft 36, the hose 11 is connected to the channel 37, and the first connecting pipe 14 is connected to the channel 37.

[0040] The coil spring can enable the winding roller 34 to be automatically wound. When the electromagnet 1 7 and the electromagnet 2 13 are powered off, the hose 11 will be wound up by the winding tube 34 under the action of the coil spring, and the hose 11 is connected to the first connecting tube 14 through the channel 37 .

[0041] To further optimize the solution, a fixing block 38 is fixedly connected to the support plate 35, a cavity 39 is opened on the fixing block 38, the center axis 36 extends into the cavity 39, the channel 37 is connected to the cavity 39, the center axis 36 is rotatably connected to the fixing block 38, and the first connecting pipe 14 is connected to the cavity 39.

[0042] When the central shaft 36 rotates, the fermentation liquid enters the cavity 39 through the channel 37 and then enters the first connecting pipe 14 .

[0043] A further optimized solution is that a mounting groove is opened on the rotating shaft 5, the electric telescopic rod 43 is fixedly connected in the mounting groove, the stirring frame 6 includes an outer ring 40, a plurality of connecting rods 41 are fixedly connected in the outer ring 40, a connecting plate 42 is fixedly connected to the connecting rod 41, the electromagnet 7 is fixedly connected to the connecting rod 41, and the output end of the electric telescopic rod 43 is fixedly connected to the connecting plate 42.

[0044] The electric telescopic rod 43 drives the connecting plate 42 to move up and down, thereby driving the entire stirring frame 6 to move up and down. In this embodiment, the connecting rod 41 is also connected to a plurality of supporting rods, which makes stirring more convenient.

[0045] According to a further optimized solution, a first gear 44 is fixedly connected to the rotating shaft 5 , a second gear 45 is fixedly connected to the motor 8 , the first gear 44 is meshed with the second gear 45 , and a plurality of legs 46 are fixedly connected to the lower tank body 2 .

[0046] The motor 8 drives the second gear 45 to rotate, and the second gear 45 drives the first gear 44, so that the rotating shaft 5 rotates.

[0047] The working principle of the device is to add raw materials into the fermentation tank through the liquid adding port. When adding raw materials, open the second valve 10, and close the second valve 10 after adding. If the fermentation liquid needs to be stirred during the fermentation process, the electric telescopic rod 43 can drive the stirring frame 6 to move up and down, so that the fermentation liquid in the lower tank body 2 can be stirred. When it is necessary to sample the fermentation liquid, the stirring frame 6 moves up, and the electromagnet 1 7 and the electromagnet 2 13 are energized, so that the electromagnet 2 13 and the electromagnet 1 7 are close to and adsorbed together, and the stirring frame 6 moves down, and the electromagnet 2 13 and the pipe head 12 move down until they enter the fermentation liquid. When sampling, the stirring frame 6 slowly enters into the fermentation liquid to prevent the fermentation liquid from being violently stirred. When the pipe head 12 enters the fermentation liquid with the stirring frame 6, the vacuum pump 18 is started, and the transfer box 17 is evacuated through the second connecting pipe 19, so that the fermentation liquid enters the transfer box 17 through the hose 11 and the first connecting pipe 14. When the fermentation liquid in the transfer box 17 reaches a certain amount, the vacuum pump 18 is turned off, and the first solenoid valve 20 and the second solenoid valve 21 are closed at the same time to prevent the transfer box 17 from leaking. The third solenoid valve 25 is opened, and the external air enters the transfer box 17 after being filtered by the air filter 23. The air pressure in the transfer box 17 is balanced with the outside, so as to facilitate the outflow of the fermentation liquid. When the first solenoid valve 20 is closed, there will be residual fermentation liquid in the first connecting pipe 14 and the hose 11. At this time, the fourth solenoid valve 30 is opened, and the air pump 27 is started. The air pump 27 blows the gas in the lower tank body 2 into the first connecting pipe 14 and the hose 11, thereby preventing the fermentation liquid from remaining in the first connecting pipe 14 and the hose 11. When all the fermentation liquid samples in the transfer box 17 are discharged, in order to avoid the residual fermentation liquid in the transfer box 17 affecting the next time, the transfer box and the discharge pipe 15 can be cleaned by the water pump 31. During cleaning, the third valve 16 is opened, and the first solenoid valve 20, the second solenoid valve 21, the third solenoid valve 25 and the fourth solenoid valve 30 are closed, so that the cleaned liquid can be directly discharged from the transfer box 17.

[0048] In this embodiment, the hose 11, the transfer box 17, the air pump 27, and the air filter 23 are all four groups, and the water pump 31 is one group.
