Container for decomposable material such as excrement

A container for decomposable material such as excrement, comprising a composting chamber (20) with two end walls (11, 12) and a curved bottom (29) the surface of which substantially coincides with a rotational surface, there being a stirring means (26) rotatably mounted and driven by an electric motor (24) and provided with a plurality of stirring members which, during the rotation of the stirring means, move a portion of the composting material (27) along the bottom of the composting chamber, there being an emptying opening (18) in the curved bottom for discharging at least partially decomposed material to a collection container (21), characterized in that the rotational direction of the electric motor (24) and the stirring means (26,26a), respectively, is reversible by means of switch means (38) so that, in the normal direction of rotation of the stirring means, feeding takes place in a direction from the top of the emptying opening and downwards, while discharge of at least partially decomposed material takes place by reversing the direction of rotation so that material is fed along the bottom (29) of the container and up to the emptying opening (18) and out through the latter to the collection container (21), and that the stirring members include bar-shaped members (13b-13f, 50) extending between the end walls along a rotational surface substantially concentric with the bottom surface (29), said rotational surface lying close to the bottom surface, the cross-section of each bar-shaped member having a width which is substantially greater than the radial thickness of the bar-shaped member.
