When activated, the light emitted from each LED 33 is allowed to pass through the seawater inside the culture vinyl bag 7, while the air pump 41 passes through the air filter 43 and the ultraviolet sterilizer 44. The purified and sterilized air is aerated into the seawater of the culture vinyl bag 7 via the bubble disperser 9.

Therefore, the microalgae in seawater stored in each culture vinyl bag 7 are incubated using light energy emitted from the LED 33 and air components dissolved in the aeration process, and the lower tank 2 in winter. It is possible to maintain the incubation temperature required by heating the stored water stored in the heater (8), and to cool the culture sea water and maintain the culture temperature by flowing cold seawater or tap water in the nearby sea area into the lower tank (2) in summer Done.

It is possible to easily wash scale (fog) and foreign substances on the inner surface, and also to recycle the washed cultured vinyl bag (7), thereby reducing the cost and labor according to the use and maintenance of the culture apparatus (10). Can also contribute significantly.

In addition, by using the heating method of the storage water using the lower water tank (2) and the cooling method according to the cold water flow, to ensure that any set temperature required for cultivation of microalgae is always maintained regardless of indoor or outdoor seasons. In the event of a failure of the heater 8 or the like, it is easy to replace with a new product and more stable culture is possible by blocking the situation where the microalgae are killed by directly contacting the surface of the high temperature heater 8.

Particularly, only one or two heaters 8 for heating the stored water stored in the lower tank 2 need to be used without having to separately install the heaters 8 for each culture vinyl bag 7, When cooling the cultured seawater in summer, by applying the cooling method to circulate the cold seawater or tap water in the nearby sea to the lower water tank (2) without using a separate cooling device, the energy required to maintain the temperature of the cultured seawater is also maximized. You can save.

In addition, by supplying the external air used for the cultivation of microalgae through physical filtration and ultraviolet sterilization to minimize contamination, it is possible to prevent contamination of cultured seawater due to external air and the death of the microalgae due to this. In addition, by using the vinyl bag case (6) that can be disassembled and assembled, it is possible to easily replace and use the culture plastic bags (7) of various capacities as necessary, thereby securing a wider range of applicability and application range of the culture device (10) can do.

Ultimately, by adopting a breakthrough culture method that is hardly restricted in securing space according to the culture facility by breaking away from the existing culture method, it is possible to develop not only aquaculture facilities such as seedling production, but also the development of health food, sewage treatment or CO ₂ removal. It is possible to provide a very economical and efficient culture apparatus that can be used very suitably for the use and research of biofuels and the like, and the high-density mass culture of microalgae is possible while greatly reducing the cost burden.
