Abstract
ABSTRACT
The invention relates to an apparatus for continuous impregnation of granular products by spraying.
The apparatus is characterised in that it comprises a sheath or conduit with its axis vertical, open at its lower end (1) and having at its upper part an inlet orifice (2) for granular products to be impregnated, a chicane arrangement (3 to 5) disposed inside the conduit below the said orifice (2) and arranged to constrain the said products so as to flow out under gravity in a vertical tubular column (N) in the interior of the conduit (1), and a plurality of injectors (6) fixed to the wall of the conduit, directed towards its centre and able to project in the form of a mist a liquid or slightly pasty product for treatment or addition to the granular product.
Optionally, a tubular guide (9) is fitted in the conduit to shape the column and prevent the spray form the jets crossing the conduit.
A particular application is to the impregnation of granulation chemical fertilisiers.

Claims (9)
1. Apparatus for continuous impregnation of granular products or their analogues by spraying, comprising a sheath or conduit with its axis vertical, open at its lower end and having at its upper part an inlet orifice for granular products to be impregnate, a chicane arrangement disposed inside the conduit below the said orifice and arranged to constrain the said products so as to flow out under gravity in a vertical tubular column in the interior of the conduit, and a plurality of injectors fixed to the wall of the conduit, directed towards its centre and able to project in the form of a mist a liquid or slightly past product for treatment or addition to the granular product.
2. Apparatus according to claim 1, in which the said arrangement of chicanes comprises, successively from the said orifice and co-axially thereto, a funnel-shaped deflection plate, a conical deflection plate and a funnel-shaped deflection plate.
3. Apparatus according to claim 1 or 2, in which the injectors are regularly distributed by being offset angularly and following circles at different heights.
4. Apparatus according to claim 1 or 2, in which the injectors are connected, on the one hand to a supply system for product to be sprayed and, on the other hand, to a supply system for compressed air.
5. Apparatus according to claim 1 to 2, which also comprises a tubular guide positioned in the interior of the column.
6. A granular product impregnated by spraying of a liquid product, obtained with an apparatus according to claim 1.
7. A method of continuously impregnating a granular or analogous product by spraying, the apparatus being substantially as hereinbefore described with reference to the accompanying drawing.
8. A granular product impregnated by the method of claim 7.
9. A product according to claim 6 or 8, the granular part being constituted by a chemical fertiliser and in that the sprayed liquid part comprising one or more trace elements.
