Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a fermentation system. Background Technology

[0002] A fermentation system is an environment used to control the growth and metabolism of microorganisms. It is widely used in food, beverage, pharmaceutical, and biofuel industries. Its core function is to optimize the fermentation process by adjusting conditions such as temperature, pH, oxygen, and nutrients to efficiently produce the target product. Its main components include fermenters, pH adjustment systems, aeration systems, temperature control systems, and feed / discharge systems.

[0003] In existing fermentation systems, the pH adjustment system, aeration system, and temperature control system each have independent interfaces with the fermenter, resulting in numerous interfaces and pipes on the fermenter. This abundance of interfaces and pipes causes inconvenience in layout and maintenance. Furthermore, the acid or alkali solution for the pH adjustment system enters the fermenter through an acid / alkali inlet at the top. Although stirring is performed, the large volume of the fermenter makes it difficult for the acid or alkali solution added at the top to mix thoroughly and evenly with the entire feed solution, resulting in inadequate pH adjustment.

[0004] Therefore, those skilled in the art are dedicated to developing a fermentation system that facilitates the layout and maintenance of interface pipelines and allows for sufficient and uniform adjustment of the pH value of the feed solution. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is that the existing fermentation system has many interfaces and pipelines, which leads to layout and maintenance problems, and the pH adjustment effect is not good due to insufficient and uneven mixing of acid and alkali solutions with the material liquid in the fermentation tank.

[0006] To achieve the above objectives, this utility model provides a fermentation system, including a fermenter, an acid tank, an alkali tank, an oxygen tank, a steam generator, and an atomizing nozzle. The oxygen tank is connected to the bottom of the fermenter via an oxygen pipeline. A booster pump, an oxygen solenoid valve, and an atomizing nozzle are sequentially installed on the oxygen pipeline. The atomizing nozzle has an acid / alkali inlet and a steam inlet on its side. The steam generator is connected to the steam inlet via a first steam pipeline, which is equipped with a first steam solenoid valve. The acid tank and alkali tank are connected to the acid / alkali inlets via acid and alkali pipelines, respectively. The acid pipeline is equipped with an acid solenoid valve and an acid flow meter, and the alkali pipeline is equipped with an alkali solenoid valve and an alkali flow meter. A pH sensor, a temperature sensor, and a pressure sensor are installed inside the fermenter.

[0007] During operation, based on feedback from the pH sensor, when pH adjustment is needed, the controller opens the acid or alkali solenoid valve to supply acid or alkali to the atomizing nozzle. Based on feedback from the temperature sensor, the controller opens the first steam solenoid valve to supply steam to the atomizing nozzle. Simultaneously, as oxygen is ejected from the atomizing nozzle under the action of the booster pump, oxygen, acid or alkali, and steam mix and are atomized in the atomizing nozzle, and supplied into the fermenter from the bottom. The atomized acid, alkali, and steam rise with the oxygen bubbles in the liquid, mixing thoroughly and evenly with the liquid, making the fermentation system more effective in oxygen supply, pH adjustment, and steam temperature control and sterilization.

[0008] Furthermore, the fermenter is equipped with an outer jacket, and the steam generator is connected to the outer jacket via a second steam pipeline, on which a second steam solenoid valve is installed. By introducing steam into the outer jacket, the temperature of the fermenter can be further assisted in its regulation, improving temperature control efficiency.

[0009] Furthermore, the steam generator is connected to the top of the fermenter via a third steam pipeline, and a third steam solenoid valve is installed on the third steam pipeline. By introducing steam into the top of the fermenter, the pressure inside the fermenter can be regulated based on feedback from a pressure sensor.

[0010] Furthermore, the fermentation tank is equipped with a stirring mechanism.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Acid or alkali solution, steam, and oxygen are mixed and atomized through atomizing nozzles and supplied into the fermenter from the bottom. The atomized acid, alkali, and steam rise with oxygen bubbles in the liquid, mixing thoroughly and evenly. This allows the fermentation system to achieve more complete effects in oxygen supply, pH adjustment, and steam temperature control and sterilization. Furthermore, the merging of multiple materials at the atomizing nozzles before entering the fermenter reduces the number of interface pipes, simplifying pipe layout and maintenance.
