Abstract:
A microalgae culture broth producing system includes a device for culture broth sterilization using a micro air bubble generator, an air compression and pressure equalization device for the injection of carbon dioxide and oxygen in the atmosphere into the culture broth. The system also includes an air chilling device to maintain suitable culture broth temperature when water temperature is too high, an automatic carbon dioxide supply device to promote photosynthesis, and a sealed vertical photobioreactor to block out pollutants and increase dissolved carbon dioxide and oxygen concentration. The system further includes a high-efficiency harvesting device using hollow fiber membranes, and a hot air drying device using the waste heat generated by air compression.
