Containing apparatus comprising: - a container of material having at least one lateral wall that defines an internal cavity and provided with at least two lateral apertures (16a, 16b) made on opposite sides with respect to a vertical plane passing through a longitudinal axis of said container, and - a discharge device provided with at least a movement member having a rotary shaft inserted into said two lateral apertures (16a, 16b) to pass through said internal cavity of said container in through manner, and selectively rotatable in a determinate direction of rotation around its own axis of rotation transverse to said longitudinal axis, and a plurality of blades mounted radially on said rotary shaft and defining corresponding containing cells having the function of temporarily containing said material in order to move it, due to the effect of the rotation of said rotary shaft in said determinate direction of rotation, from a zone of said internal cavity, disposed above said rotary shaft, toward a discharge aperture of said container disposed below said rotary shaft, wherein said rotary shaft is divided into a plurality of axial zones (A, B, C, D, E, F, G) along said axis of rotation, and wherein on each of said axial zones (A, B, C, D, E, F, G) a corresponding wheel with blades is keyed, characterized in that said wheels are positioned along said axis of rotation so as to be adjacent with each other and in succession, said blades covering the whole zone comprised between one side to the other of said internal cavity, and in that between each pair of adjacent wheels a separator disc is disposed, configured to prevent said material from passing from one of said wheels to the other. - a container of material having at least one lateral wall that defines an internal cavity and provided with at least two lateral apertures (16a, 16b) made on opposite sides with respect to a vertical plane passing through a longitudinal axis of said container, and - a discharge device provided with at least a movement member having a rotary shaft inserted into said two lateral apertures (16a, 16b) to pass through said internal cavity of said container in through manner, and selectively rotatable in a determinate direction of rotation around its own axis of rotation transverse to said longitudinal axis, and a plurality of blades mounted radially on said rotary shaft and defining corresponding containing cells having the function of temporarily containing said material in order to move it, due to the effect of the rotation of said rotary shaft in said determinate direction of rotation, from a zone of said internal cavity, disposed above said rotary shaft, toward a discharge aperture of said container disposed below said rotary shaft, wherein said rotary shaft is divided into a plurality of axial zones (A, B, C, D, E, F, G) along said axis of rotation, and wherein on each of said axial zones (A, B, C, D, E, F, G) a corresponding wheel with blades is keyed, characterized in that said wheels are positioned along said axis of rotation so as to be adjacent with each other and in succession, said blades covering the whole zone comprised between one side to the other of said internal cavity, and in that between each pair of adjacent wheels a separator disc is disposed, configured to prevent said material from passing from one of said wheels to the other.
