DETAILED DESCRIPTION OF THE INVENTION

(9) The structure, characteristics and advantages of the system of the invention will be better understood with the following description, made in reference to the realization examples shown in the enclosed drawings.

(10) In FIG. 1 a system for the processing of solid waste and organic products is shown; this system is composed of, at least, one cylindrical cavity (1) which is closed in both bases and is equipped with a dragging spindle (2) whose axis (3) is supported by the lids (4 and 5) which close the cylindrical cavity (1) in its extreme sections. Out of the lid (4) partially sticks out the axis (3) for its connection to a motor mechanism (6). The axis (3) is supported by the lids (4 and 5) by means of bearings (7), FIGS. 2 and 3, from which the one situated next to the motor area (6) is closed by means of a magnetic plugging mechanism (8), of well-known structure, which spins around and together with the same axis and makes possible the blockage of the oiling of the corresponding bearing. Inside the cylindrical cavity (1) and near the motor area of the system, it is arranged a transverse partition wall (9), which serves as a means of isolating and protecting the motor area of the product or waste which is under treatment, avoiding contact between the mechanical parts and the product.

(11) The base (4) which closes the cylindrical cavity on the side of the motor area includes, besides, a security system (10) by means of spinning wedges, of well-known structure in itself, according to what can be better appreciated in the detail of FIG. 4.

(12) According to what can be appreciated in FIG. 1, in the axis (3) of the spindle (2) there are installed mixing blades (11), which are situated in the consecutive steps of the helix of the dragging spindle (2) and present an opposite curvature to that one of the helix of the dragging spindle (2), conforming a mixing helix with a direction of advance opposite to that one of the helix of the dragging spindle (2).

(13) The cylindrical cavity (1) is equipped with a loading area (12) for the product to be treated, loading area which in the example represented in FIG. 1, is situated near the closing base (5) of the cavity (1) and a unloading area (13) for the exit of the treated product, unloading area which is situated near the closing base (4) of the cylindrical cavity.

(14) The spindle (2) spins with a direction of advance from the loading area (12) to the unloading area (13) whereas the mixing blades (11) do it in the opposite direction.

(15) The cylindrical cavity (1) is also equipped with an entrance (14) and an exit (15) for vapour. Finally, the cylindrical cavity (1) will be arranged with mechanisms of control of vapour, vapour which is injected through the entrance (14) of vapour.

(16) Preferably the system will be composed of two cylindrical cavities (1 and 1), superimposed, as it is shown in FIG. 5, with the unloading area (13) of the cavity (1) connected to the loading area (12) of the cavity (1). In the loading area (12) of the cavity (1) and in the unloading area (13) of the cavity (1) guillotine valves or a gate blade (16-16) can be installed. To the entrance of vapour (14) a mechanism of supply of saturated vapour will be connected.

(17) In FIG. 6 it is shown a system composed of four cylindrical cavities which are superimposed, connected in series of two and arranged in a container (17), which facilitates its transport and installation and even the extension of the system by means of the superimposition of two or more containers with connection in series of superimposed cavities by means of flexible junctions (18).

(18) Finally, in FIG. 7 it is shown a disposition in a high level, in which the system is composed of a number of superimposed cavities which are connected consecutively in series, including after each two superimposed cavities a disposition equal to that described in reference to the FIG. (5).

(19) In the different dispositions, in each pair of superimposed cavities (1 and 1) the same references have been used with the apostrophe in the references of the cavity (1).

(20) The system of the invention, starting from the disposition in FIG. 5 or 6, can be extended in a modular way, depending on the volume of the product to be treated.

(21) Preferably, the helix of the dragging spindle (2) will be of a slightly smaller diameter than the internal one of the cylindrical cavity (1), so that between both edges a void space is formed; a space which will be occupied by the waste to be treated, in a way that direct friction between the waste that the spindle (2) drags and the internal surface of the cavity (1), is removed.

(22) The system of the invention, due to its structure, can work in continuum, by means of the constant load of material through each loading area (12, 12 . . . ) in each cavity (1, 1 . . . ), as treated product is unloaded through the unloading areas (13, 13 . . . ). As it can be seen in the different dispositions shown in the drawings, the cylindrical cavities will be preferably arranged in horizontal position.
