Abstract:
1. An apparatus for growing biological mass, comprising a container for accommodating a biological mass in liquid to be grown in presence of light; a plurality of light sources in an interior of said container; a first movable plate which has passages for said light sources and which is reciprocatingly movable along said light sources to clean the latter, said first plate also having first openings permeable for the liquid and for the biological mass; and a second plate located under said first plate and configured so that it is permeable for water and small algae fraction which have still to be grown but not permeable for the biological mass with fully grown algae, so that for discharging the biological mass said first and second plates are placed over one another and together moved toward a discharge so that the water can pass through both plates, while the biological mass is held on the first plate and moved toward said discharge to be discharged outwardly, further comprising means for providing a joint movement of said first and second plates with one another and connecting said first and second plates with one another for displacement toward the discharge, while disconnecting said plates from one another for process of growing of the biological mass and moving said first plate reciprocatingly for cleaning the light sources, wherein said means include a lock which locks said first and second plates with one another and unlocks said first and second plates from one another, and solenoid means which act on said lock to provide locking and unlocking of said plate.
