Abstract
A chlorella-culturing apparatus comprises a rotatable arm body fitted with a stirring mechanism for forcefully producing stirring streams by stirring blades and scraping mechanism. The scraping mechanism is so mounted on the rotatable arm body as to slide up and down. It is brought down when the chlorella-culturing apparatus discharges cultured chlorella, and rotated with the arm body in contact with a bottom board and inner peripheral surface of a chlorella-culturing tank. At least one chlorella-discharging groove is formed in the bottom board of the chlorella-culturing tank. Deposits removed by the scraping mechanism are carried together with a chlorella-culturing liquid into the discharging groove by the scraping mechanism. The central pillar and side wall of the chlorella-culturing tank have an inclined surface which is sprayed with water to prevent cultured chlorella and any other material from being deposited on said surface.
