Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a fermentation tank for biomedicine. Background Art

[0002] In the preparation process of biological drugs, fermentation is an important part of bioengineering, and fermentation tanks are often used. Fermentation tank equipment provides the best growth and reproduction conditions for engineered bacteria or engineered cells, that is, it provides external conditions such as optimal temperature, pH, stirring rate and dissolved oxygen content.

[0003] After searching, the Chinese patent with announcement number: CN215440468U discloses a biomedical fermentation tank, including a fermentation tank body, a rotating shaft is arranged inside the fermentation tank body, a motor for driving the rotating shaft is arranged outside the fermentation tank body, a spiral blade is arranged on the rotating shaft, the outer edge height of the spiral blade is lower than the inner edge height, a heating wire is embedded in the spiral blade, the interior of the rotating shaft is a cavity, a control board is arranged outside the fermentation tank body, the control board is connected to the heating wire through a connecting wire, and the connecting wire passes through the cavity in the rotating shaft. The fermentation tank in the utility model drives the medicine at the bottom of the tank body upward and stirs it by the spiral blade, and stirs it evenly. During the stirring process, the outer edge of the spiral blade is tilted downward, which can avoid the generation of bubbles in the stirring process that affects the normal fermentation; the temperature is controlled by the heating wire on the spiral blade to ensure the uniform temperature in the fermentation tank.

[0004] The working principle of the patent mentions that "the motor 3 is started, and the rotation of the motor 3 drives the spiral blade 4 to rotate, so that the liquid medicine at the bottom of the fermentation tank body 1 is spirally transported upward, and stirred at the same time to make the stirring uniform, and the heating temperature of the heating wire 5 is controlled by the control panel 6 to adjust the temperature in the fermentation tank, and the temperature is adjusted during stirring to make the temperature in the fermentation tank uniform". However, after the fermentation tank is used, between different production batches, or when fermenting with different microbial strains, the user will use a stirring device to clean the tank body and reuse it. However, due to the limitation of the stirring device, the user will have four corners of the tank body when cleaning, which makes it impossible to completely eliminate the waste, sediment and dirt deposited in the tank. In addition, since the sediment will accumulate in the tank body when the liquid is stirred, when the user takes the liquid, the liquid is turbid and the purity is not high. In view of the above problems, a biomedical fermentation tank is proposed to solve the above problems. Utility Model Content
