NOVELTY - The device for composting of biogenic materials, comprises a container in which materials are introduced at the top, storage chamber (2) that is arranged below a reactor chamber (1), which passes the materials by gravity with air introduction, slide surfaces and slide vanes (4). The slide surfaces that stop the downward material flow, are provided. The reactor chamber of the storage chamber is separated with slide vanes of 140degrees. The reactor chamber exhibits a container wall (9) with conically formed slide surfaces, which are arranged diagonally downward to the chamber.    USE - For composting of biogenic materials.    ADVANTAGE - The device is cost effective and reaches optimal conversion rates of fresh biowaste to compost. The compost is easily removed from a storage container by shovel or similar without the weight of heap affecting the shovel.    DETAILED DESCRIPTION - The device for composting of biogenic materials, comprises a container in which materials are introduced at the top, storage chamber (2) that is arranged below reactor chamber (1), which passes the materials by gravity with air introduction, slide surfaces and slide vanes (4). The slide surfaces that stop the downward material flow, are provided. The reactor chamber of the storage chamber is separated with slide vanes of 140degrees. The reactor chamber exhibits a container wall (9) with conically formed slide surfaces, which are arranged diagonally downward to the chamber. The slide surfaces are designed as tube, half tube, funnel or sphere, which are not intended at the inner wall of the container and are fastened in such a way that the fastening does not form a support for bridging. The slide surfaces partly exhibit a strong braking surface e.g. wavelike recesses, grooves, knobs, or any other geometrical form, which causes a strong braking action. The slide surfaces are intended and are arranged in the same level or in different height. The braking action of the slide surfaces is adjustable. The angle of incidence of the slide vane is changeable. The tube with different braking action, is intended over the circumference that is carried out by rotatable action.    DESCRIPTION OF DRAWING(S) - The drawing shows a conical container:    Reactor chamber; (1)    Storage chamber; (2)    Adjusting screws; (3)    Slide vanes; (4)    Container wall. (9)
