A Novel Device for the Soil Sterilizing in Sustainable Agriculture

In this paper a machine that performed the soil sterilization has been designed. The soil is cut and put in a loading hopper and downloaded in a rotating cylinder placed on the machine. The fins located inside the rotating cylinder performed the crushing and the mixing of the soil. Each soil particle through the temperature field ranged between 290–1900° C for 3–5 min and a preset output soil temperature of 130–140° C is reached and discharged downward. It maintained the process temperature long enough, to allow the elimination of the infesting organisms located in the considered soil.
