Study of a Soil thermo-sterilizer Machine

It has been designed and realized a machine for the soil sterilization by mean the soil, that happens in a rotating furnace with a direct flame, and in which the soil is shattered and broken up. Insofar every single particle of the considered soil comes to contact with direct flame, and in this way ,therefore, it is possible to obtain that the whole mass of the soil reach the same temperature required of 353 K- 358 K. The system considered allows to perform the soil sterilization in the following way: on a soil line (where the transplantation of the seedlings is performed), as required by agronomic specifications; on a volume of well determined soil (from the width and depth of the cutting tools), therefore the precision and the accuracy of the considered operation are guaranteed; without accumulations of toxic residues in the treated soil ; without asking for hard-working manual operations, neither specialized work-man for the management of the vapor generators; with energetic consumptions lower of the other systems in force.
