Abstract:
     The present invention provides a closed cultivating method of spirulina and its apparatus. It is characterized by using a closed circulation vertical type tube-line cultivating trough. The algae strain and culture liquor are placed in said cultivating trough, and a CO2 mixed gas is introduced into the cultivating trough through air-feeding tube and air-diffusion hole of the cultivating trough bottom by blower and at the same time the air-lifting principle can make algae liquor circularly flow, and its test and control device can implement the automatic supplementation of culture liquor and regulation of CO2 gas mixing ratio, illumination and temp., and its algae liquor collection and culture liquor recovery separator can collect algae slurry and recover culture liquor, and the algae slurry passes through the processes of cleaning, drying, and is formed into algae powder or can be made into various product.
