Abstract

Procédé pour transformer le purin brut, tel qu'on le trouve dans les exploitations agricoles, en particulier d'élevage de bétail (veaux, vaches, cochons en particulier), pour en faire de l'engrais solide coulant. Ce procédé comporte les trois phases successives suivantes: (a) on députréfie le purin brut dans une installation biologique d'extraction de gaz en le remuant, à la température ambiante ou à une température légèrement supérieure, pendant une à deux semaines, afin d'éliminer les gaz d'hydrocarbures, les gaz contenant du soufre et les gaz contenant de l'azote, en particulier le méthane, H2S et NH3; on obtient ainsi un purin députréfié colloïdal homogène pratiquement inodore; (b) on transforme et on rend granuleux le purin députréfié colloïdal obtenu lors de la phase (a) dans un mélangeur brasseur chauffable, en particulier un tambour rotatif, avec un sel minéral de calcium, le rapport entre le purin et le sel minéral de calcium étant de l'ordre de 1:1 à 4:1, en le remuant et en le chauffant jusqu'à une température de l'ordre de 30 à 80°C; et (c) on concasse encore le produit solide obtenu lors de la phase (b), le cas échéant, dans un appareil de broyage habituel, et on le moud en particulier jusqu'à obtenir la granulométrie désirée; enfin on l'agglomère en boulettes en ajoutant les produits de désintégration habituels pour obtenir un engrais coulable.
