[0027] Reference Figure 1 , a real-time monitoring device for fermentation liquid viscosity, comprising:

[0028] A fermentation tank 100, used for fermentation;

[0029] A discharge pipe 210 and a recovery pipe 220 are connected between the sealed tank 200 and the fermentation tank 100. The discharge pipe 210 is provided with a first switch 211, and the recovery pipe 220 is provided with a second switch 222;

[0030] A funnel 300 is disposed in the sealed tank 200. The funnel 300 is disposed below the discharge pipe 210 and receives the fermentation liquid from the discharge pipe 210. A solenoid valve is disposed at the bottom of the funnel 300.

[0031] and timers;

[0032] Among them, a first air pipe 111 and a second air pipe 121 are connected between the fermentation tank 100 and the sealed tank 200, the first air pipe 111 is connected to the air inlet pipe 110, and a first switching valve 112 is provided at the connection between the air inlet pipe 110 and the first air pipe 111; the second air pipe 121 is connected to the air outlet pipe 120, and a second switching valve 122 is provided at the connection between the air outlet pipe 120 and the second air pipe 121.

[0033] The sealed tank 200 to be measured is connected to the fermentation tank 100, and the fermentation liquid is driven to circulate between the fermentation tank 100 and the sealed tank 200 by air pressure. The viscosity of the fermentation liquid can be measured in a closed environment, thereby reducing the loss of the fermentation liquid and increasing the yield.

[0034] The funnel 300 in the sealed tank 200 is used to specifically measure the viscosity of the fermentation liquid. The top of the funnel 300 is provided with a first sensor 310, and the bottom of the funnel 300 is provided with a second sensor 320. Figure 2 The first sensor 310 and the second sensor 320 are electrically connected to the same controller, the solenoid valve is electrically connected to the controller, and the timer is electrically connected to the controller. The controller receives a signal from the first sensor 310 to control the solenoid valve to open or close and controls the timer to start timing; the controller receives a signal from the second sensor 320 to control the timer to stop timing.

[0035] It should be mentioned that the first switching valve 112 and the second switching valve 122 are both three-way switching valves. The first switching valve 112 can connect the air inlet pipe 110 to the fermentation tank 100 or the sealed tank 200, and the second switching valve 122 can connect the air outlet pipe 120 to the fermentation tank 100 or the sealed tank 200. In actual use, the second switching valve 122 is controlled to connect the air outlet pipe 120 to the sealed tank 200, while the air inlet pipe 110 to the fermentation tank 100 is connected to the sealed tank 200. The first switch 211 is turned on to allow the fermented liquid to pass through the discharge pipe 210 into the sealed tank 200 and drip into the funnel 300. When the fermented liquid in the funnel 300 reaches the top of the funnel 300, the first sensor 310 is turned on, and the second switching valve 122 is adjusted to connect the air outlet pipe 120 to the fermenter 100. The solenoid valve is opened to allow the fermented liquid to drip and start timing. When all the liquid has dripped, the second sensor 320 transmits a signal to the controller, and the controller controls the timer to stop timing to complete the measurement.

[0036] After the test is completed, the first switching valve 112 is operated to connect the air inlet pipe 110 to the sealed tank 200 and disconnect it from the fermentation tank 100. The air inlet pipe 110 continues to discharge sterile air and allows the fermentation liquid in the sealed tank 200 to enter the fermentation tank 100 through the recovery pipe 220.

[0037] In some embodiments, the fermentation tank 100 is wrapped with a jacket 130 for keeping the fermentation liquid warm.

[0038] In some embodiments, a rotatable stirring shaft 140 is inserted into the fermentation tank 100. The stirring shaft 140 is used to stir the fermentation liquid in the fermentation tank 100 so that the fermentation liquid after detection is remixed into the original liquid.

[0039] In some embodiments, a plurality of stirring blades 141 are arranged on the shaft of the stirring shaft 140 , and the stirring blades 141 are arranged in several layers from top to bottom. The stirring blades 141 are used to stir the fermentation liquid sufficiently and evenly.

[0040] In some embodiments, one end of the air inlet pipe 110 inserted into the fermenter 100 is connected to an air distributor 1111 to allow sterile air to fully enter the fermenter 100 .

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
