Description

A non-natural amino acid bio-fermentation device Technical Field

[0001] This utility model relates to the technical field of chemical equipment, and in particular to a non-natural amino acid bio-fermentation device. Background Technology

[0002] Amino acid fermentation is a process that requires oxygen. Currently, all known amino acid-producing bacteria are aerobic bacteria, meaning that an adequate amount of sterile air must be supplied for the bacteria to reproduce and accumulate the necessary metabolic products. Therefore, how to supply oxygen rationally and efficiently has become an indispensable part of amino acid production.

[0003] Existing amino acid bio-fermentation devices, such as the amino acid bio-fermenter disclosed in utility model patent application number 202421242569.4, mainly include a bio-fermenter and an upper-mounted drive motor. A tension steel wire rope is connected to the side of a central connecting column. A connecting support outer column is located on the side of the motor connecting shaft column. A compression connecting spring is located inside the connecting support outer column, and a connecting insertion inner column is located at the end of the compression connecting spring. In use, rotating the adjusting knob raises or lowers the connecting threaded column, which can stretch or release the tension steel wire rope to adjust the distance between the agitator body and the inner wall of the bio-fermenter, allowing the amino acid bio-fermenter to adjust the stirring according to different fermentation processes.

[0004] However, most existing fermentation devices have small gas-liquid contact areas and low mass transfer efficiency, making it difficult to meet the dissolved oxygen requirements of the entire fermentation process. Moreover, in the non-natural amino acid bio-fermentation process, the temperature and pressure inside the tank will rise, and existing fermentation devices cannot adjust the temperature and pressure inside the tank in a timely manner, which can easily affect the fermentation effect. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a non-natural amino acid bio-fermentation device that not only increases the contact area between oxygen and solution, making it easier to meet the dissolved oxygen requirements of the entire fermentation process, but also allows for timely regulation of temperature and air pressure to avoid affecting the fermentation effect.

[0008] Preferably, the temperature control mechanism includes an insulation layer, an inlet pipe, a drain pipe, two sets of second valves, and a first thermometer.

When the temperature drops, the two sets of second valves are opened, and the cold water is discharged through the drain pipe. The hot water is then transported back into the sandwich through the inlet pipe.

[0009] Preferably, the stirring mechanism includes a motor, a reducer, a drive shaft, a triangular bracket, multiple sets of fan blades, and a second thermometer. The bottom end of the motor is connected to the top end of the tank, and the bottom end of the reducer is also connected to the top end of the tank.

The second thermometer detects the temperature of the solution in the cavity, facilitating timely replacement of the hot water in the jacket. The motor is started, and the motor drives the drive shaft to rotate through the reducer. The drive shaft drives the multiple sets of fan blades to rotate, stirring the solution.

[0010] Preferably, multiple sets of fan blades are also installed at an angle on the drive shaft; the angled installation can not only break the laminar boundary layer and increase the turbulence intensity, but also promote the uniform dispersion of bacteria and substrate, accelerate the transfer of dissolved oxygen, make the heat evenly distributed, and avoid local overheating.
