PURPOSE:To perform a small-scale hydroponic culture in high efficiency by scooping the hydroponic liquid in a water-tank to the top of the stored liquid and circulating the scooped liquid while diffusing into the stored liquid. CONSTITUTION:A hydroponic liquid is stored in a culture tank 10 and a motor 1 is energized to rotate a scooping blade 4 in a hollow cylinder 2. The hydroponic liquid is sucked through the suction port 6 opened at the bottom of the hollow cylinder, lifted in the hollow cylinder 2, discharged from the upper water-outlet port 7 to a receiving pan 8, flowed down through a water-pipe 9 and returned to the hydroponic liquid. |
