Description

Technical Field

[0001] The utility model relates to the technical field of synthetic bacteria production, and more specifically, to a fermentation stirring device. Background Art

[0002] Photosynthetic bacteria are the earliest prokaryotes that appeared on Earth, are ubiquitous in nature, and have a primitive light energy synthesis system. During the fermentation growth of photosynthetic bacteria, in order to increase the growth rate, the photosynthetic bacteria need to be repeatedly stirred by a stirring device.

[0003] After searching, a Chinese patent with publication number CN217556171U discloses an energy-saving photosynthetic bacteria culture device. The advantage of this structure is that the culture tank is placed in the sun, and sunlight is used to penetrate the culture tank to irradiate the photosynthetic bacteria culture solution inside, thereby promoting the growth and reproduction of photosynthetic bacteria. At the same time, a driving source is used to drive the stirring head to continuously stir the liquid in the culture tank, so that the photosynthetic bacteria in the culture tank are evenly exposed to light, eliminating the need for light irradiation, and has the effect of energy saving and environmental protection.

[0004] However, in actual use, since the bacteria have a certain viscosity and are easy to stick to the inner wall of the culture tank, and when the bacteria are stirred by the stirring head, the stirring width is limited, resulting in a certain distance between the stirring head and the inner wall of the culture tank. Therefore, it is not convenient to scrape off some of the bacteria stuck to the inner wall of the culture tank, which will cause the bacteria inside the culture tank to not be fully mixed, thereby affecting the efficiency of bacterial growth.
