A process and mechanism to produce granulated organic-mineral fertilizer based on concentrated vinasse, comprising specific conditions of raw material preparation, volume and amounts of mixtures, humidity of the materials used in the mixture, homogenization, granulation, drying and packaging, relation on amount of the product intended to granulate versus length of the granulator cylinder, temperature of the gases for draying, speed of the gas for draying and relation on the length versus diameter of the dryer. To improve the fertilizer composition and its mixing with conventional fertilizers, the present invention uses other sub-products from the sugar cane mill and alcohol distillery industries to obtain organic-mineral fertilizers that replace conventional fertilizers, providing organic materials and microorganisms, required for the reactivation of the soil fertility and a superior approach by the plants, resulting in an increasing of the harvesting productivity and the use of smaller amounts compared with conventional fertilizers. |
