Abstract

L'invention a pour objet le séchage d'un courant de déchets organiques. On envoie le courant 1 dans une zone de séchage 5 qui provoque le séchage et l'évaporation de l'eau contenue dans le courant et la formation d'un effluent 6 comprenant les déchets organiques particulaires et l'eau; on sépare l'effluent dans une zone de séparation 7 de solides et de vapeurs pour former un courant de solides secs 9 et un courant de vapeur 8; on extrudé une première portion du courant de solides secs dans une zone d'extrusion 13 et on obtient un produit dont la masse volumique apparente est d'environ 481 à 1041 kg/m**3. Procédé économique permettant de transformer les déchets organiques en engrais.The invention relates to the drying of a stream of organic waste. Stream 1 is sent to a drying zone 5 which causes the drying and evaporation of the water contained in the stream and the formation of an effluent 6 comprising the particulate organic waste and water; the effluent is separated in a separation zone 7 of solids and vapors to form a stream of dry solids 9 and a stream of steam 8; a first portion of the stream of dry solids is extruded through an extrusion zone 13 and a product is obtained having a bulk density of about 481 to 1041 kg / m ** 3. Economical process for transforming organic waste into fertilizer.
