[0002] The growth and reproduction of microorganisms are affected by various external environmental factors, among which temperature is one of the most significant factors affecting microbial growth. Different microbial species have their specific growth temperature ranges, including the three key points of minimum growth temperature, optimum growth temperature and maximum growth temperature. In order to ensure the efficient reproduction and metabolic activity of microbial strains in the laboratory or industrial production, it is necessary to accurately control the temperature of the culture environment to maintain it within the optimum growth temperature range of the strain, thereby improving the growth rate and yield of microorganisms and also ensuring the stability of the genetic characteristics of the strain and the repeatability of the culture results.

[0003] The Chinese utility model patent with the authorization announcement number CN218163810U discloses a Morchella strain cultivation constant-temperature room, which utilizes a blower and a resistance heater to provide cold air or hot air, utilizes a blast duct and a suction hood to form air circulation within the constant-temperature room body, avoids the mutual influence and offset of air in different directions, and avoids the problem of the air effect on the fungus bags on the placement plate not being obvious and the waste of air resource. However, in actual use, the fungus bags on the outer side of the placement plate have a relatively obvious air effect, while the fungus bags on the inner side have an unobvious air effect, which leads to the air effect still being uneven and affects the growth of the strain.

[0011] The air supply plate and the air suction plate have multiple air holes on their opposite surfaces.

[0012] This invention has the following beneficial effects: controlling the rotation of the rotating ring drives the support rod, the rotating cylinder and the placement plate to revolve. Because the support rod and the rotating cylinder rotate relative to each other, the bacteria in the placement tank are always facing upwards. The bacteria in the placement tank are always exposed to the air blown from top to bottom by the air supply plate and are drawn in by the air suction plate, realizing air circulation heating or cooling.
