Description

Technical Field

[0001] This utility model belongs to the field of edible vinegar production, specifically an automatic feeding and discharging system for fermentation tanks used in edible vinegar production. Background Technology

[0002] Edible vinegar is a commonly used cooking condiment. Currently, vinegar production mainly uses two methods: solid-state fermentation and liquid-state fermentation. Liquid-state fermentation uses alcohol as a raw material, adding acetic acid bacteria to ferment and brew vinegar. Therefore, liquid-state fermentation is more efficient than solid-state fermentation. Furthermore, during the liquid-state fermentation process, about one-third of the vinegar is discharged from the fermentation tank before adding more alcohol solution to continue fermentation, thus achieving continuous production. However, in the current liquid-state fermentation process, manual sampling for acidity testing is required before discharge and subsequent feeding. If the acidity test result is within the acceptable range, discharge is carried out; otherwise, fermentation continues until the acidity reaches the acceptable level. Therefore, manual acidity testing is still necessary in actual production. However, if testing is not conducted in a timely manner, the vinegar in the fermentation tank may not be discharged even when the acidity is within the acceptable range, resulting in lower production efficiency.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] An automatic feeding and discharging system for fermentation tanks used in edible vinegar production includes a raw material tank 1 and a fermentation tank 2. The bottom of the raw material tank 1 is connected to the top of the fermentation tank 2 via a pipeline. A feeding electronic pump 3, a feeding electronic valve 4, and a feeding electronic flow meter 5 are installed on the connecting pipeline between the raw material tank 1 and the fermentation tank 2. The bottom of the fermentation tank 2 is connected to a discharge pipe 6. A discharge electronic pump 7, a discharge electronic valve 8, and a discharge electronic flow meter 9 are installed on the discharge pipe 6. An acidity sensor 10 is installed in the lower part of the fermentation tank 2. A control box 11 is installed on the outside of the fermentation tank 2. The control box 11 can control the feeding electronic pump 3, the feeding electronic valve 4, the feeding electronic flow meter 5, the discharge electronic pump 7, the discharge electronic valve 8, and the discharge electronic flow meter 9 via wireless signals. The acidity sensor 10 is electrically connected to the control box 11. In use, this invention requires inputting the initial alcohol solution addition amount, the required acidity of the vinegar solution, the alcohol concentration in the raw material tank, and the discharge amount (which is the amount of alcohol solution to be added after subsequent discharge) into the control box 11. Initially, acetic acid bacteria are added to the fermentation tank 2. The control box 11 then activates the feeding electronic pump 3 and feeding electronic valve 4 to deliver the alcohol solution from the raw material tank 1 into the fermentation tank 2, while simultaneously acquiring information from the feeding electronic flow meter 5. When the alcohol solution addition amount reaches the predetermined value, the feeding electronic pump 3 and feeding electronic valve 4 are shut off. A stirring device can be installed in the fermentation tank 2 for further processing. The mixture is stirred and fermented, and the acidity sensor 10 signal is acquired in real time through the control box 11. When the acidity reaches the standard, the discharge electronic pump 7 and discharge electronic valve 8 are turned on through the control box 11 to discharge the material and the information of the discharge electronic flow meter 9 is acquired in real time. When the discharge volume reaches the predetermined value, the discharge electronic pump 7 and discharge electronic valve 8 are turned off, and then the feeding electronic pump 3 and feeding electronic valve 4 are turned on to replenish the discharged alcohol solution, thus realizing automated continuous production. At the same time, the control box 11 can automatically prepare the alcohol solution in the raw material tank 1 according to the original volume and feeding volume, which effectively improves the production efficiency.

[0016] Specifically, in this embodiment, the top of the raw material tank 1 is connected to the alcohol inlet pipe 12 and the purified water inlet pipe 13. The alcohol inlet pipe 12 is equipped with an alcohol inlet electronic valve 14 and an alcohol inlet electronic flow meter 15. The purified water inlet pipe 13 is equipped with a purified water inlet electronic valve 16 and a purified water inlet electronic flow meter 17. The control box 11 can control the alcohol inlet electronic valve 14, the alcohol inlet electronic flow meter 15, the purified water inlet electronic valve 16, and the purified water inlet electronic flow meter 17 via wireless signals. In this invention, the amount of alcohol and purified water to be added is determined based on a predetermined alcohol solution concentration. The control box 11 controls the opening of the alcohol inlet electronic valve 14 and the purified water inlet electronic valve 16 to add alcohol and purified water. The information from the alcohol inlet electronic flow meter 15 and the purified water inlet electronic flow meter 17 is acquired in real time. When the predetermined amounts of alcohol and purified water are reached, the alcohol inlet electronic valve 14 and the purified water inlet electronic valve 16 are closed. A stirring device can be installed in the raw material tank 1 to accelerate the mixing of alcohol and purified water and improve the efficiency of alcohol solvent preparation. At the same time, when replenishing the alcohol solution in the raw material tank 1, the amount of alcohol and purified water to be added is determined based on the replenishment amount and the predetermined alcohol concentration to ensure the accuracy of the alcohol solution concentration.

[0017] Specifically, in this embodiment, an electric heating plate 18 is installed in the lower part of the inner wall of the fermentation tank 2, and a temperature sensor 19 is installed in the lower part of the fermentation tank 2. The electric heating plate 18 and the temperature sensor 19 are electrically connected to the control box 11. Since acetic acid bacteria fermentation in alcohol solution has high efficiency at 20-40℃, in this utility model, the control box 11 obtains the temperature of the fermentation tank 2 in real time through the temperature sensor 19. When the temperature is lower than 20℃, the electric heating plate 18 is turned on to raise the temperature in the fermentation tank 2 to 30℃, and then the electric heating plate 18 is turned off. When the temperature is detected to be lower than 20℃ again, the electric heating plate 18 is turned on again, thereby ensuring the temperature in the fermentation tank 2 and improving the fermentation efficiency.

[0018] Furthermore, in this embodiment, the top of the fermenter 2 is connected to the acetic acid bacteria nutrient solution replenishment pipe 20. The acetic acid bacteria nutrient solution replenishment pipe 20 is equipped with a replenishment electronic valve 21, and the control box 11 can control the replenishment electronic valve 21 via wireless signals. In this invention, the acetic acid bacteria nutrient solution replenishment pipe 20 allows for convenient replenishment of the nutrients required for acetic acid bacteria growth, thereby improving the production efficiency of acetic acid bacteria and increasing fermentation efficiency. Since acetic acid bacteria are aerobic bacteria, air needs to be introduced. By setting the replenishment electronic valve 21 to close immediately after adding the acetic acid bacteria nutrient solution, the introduced air is prevented from being removed through the acetic acid bacteria nutrient solution replenishment pipe 20.

[0019] Furthermore, in this embodiment, the top of the fermentation tank 2 is connected to the air inlet pipe 22. In this invention, the air inlet pipe 22 allows for convenient air introduction to ensure the oxygen required for acetic acid bacteria production, thus ensuring the normal progress of liquid fermentation and vinegar brewing.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
