PURPOSE:To simultaneously and continuously obtain algae and oxygen under any outer environments, by continuously culturing algae in closed system. CONSTITUTION:Electromagnetic valves 50 and 72 are each opened in the directions of B C and A B. Then light from light source 18 is given through a optical fiber bundle 20 to a culture tank 10 and simultaneously a pump 14 is actuated and culture product containing an alga body is circulated to the arrow a direction in the culture tank 10 and line 12 to propagate the alga body and oxygen separated with an oxygen separator 24 is recovered through a gas pump 32, oxygen flowmeter 34, CO2 flowmeter 36 and vapor flowmeter 38 to a cylinder 40. Then the propagation of the alga body is detected with a turbidity meter 28 and when it attains definite value, the valves 50 and 72 are each opened in the directions of A C and A C and simultaneously pumps 52 and 60 are actuated and cultured product is allowed to flow to the arrow b direction of branched tube 48 and fed through a valve 50 and pump 52 into an alga body recovering vessel 54 and the alga body is recovered with a cylindrical filter 56, stored in a container 58 and used culture medium is discharged through a pump 60 into a tank 62. |
