<p>In a method and a device for drying and conditioning poultry manure or similar pasty materials in the form of particles, selective micro-organisms are, in a microbiological phase, fixed onto stable moulded carrier elements, added to the pasty material to be treated, optimum climatic conditions being generated with air conditioned for the activity of the micro-organisms. Released heat as well as water vapour are evacuated. In the case of a temperature drop, the microbiological phase is substituted by an air stream drying which is terminated when the desired desiccation degree is obtained. The device comprises a closed cylindrical tank (1) wherein there is arranged a suspended mounting which may vibrate vertically and which is comprised of two cylindrical coaxial air-tight mantels (14, 15) between which are distributed the carrier elements for the selective micro-organisms. A conduit (9) and an air distribution space (13) are provided for the air supply; the discharge of air is effected through the inner cylindrical mantel (15) and an exhaust pipe starting from the bottom of the tank.</p> |
