NOVEL SOLID STORAGE AND MARKETING FORM FOR PHYTOSANITARY COMPOSITIONS AND MEANS FOR PREPARING THE SAME

摘要

The invention relates to a solid form of storage and marketing for phytosanitary compositions based on any active substance with little or no water-soluble and solid at room temperature, especially based on herbicides meeting these characteristics. It is in the form of flakes based on a friable, brittle and water-soluble film-forming material, in which the particles of active material are distributed in particular. BR/ This solid form of storage and marketing can be prepared using an installation comprising a rotary drying drum (1) to which a thin layer of a dispersion (D) of particles of active substance is applied in an aqueous solution of a friable film-forming material and brittle dry. The portions of the surface of the drum to which the dispersion (D) is applied flow through the heated portion of the enclosure (2) at such a rate that the dispersion is dried, retracts and detaches from the surface of the drum (1) forming flakes (P).
