The present invention discloses a process and equipment for the complete thermal annihilation of proteins contained in material of animal or vegetable origin, in solid or semisolid state, that comprises the steps of: (a) previously milling the material of animal or vegetable origin to assure that the drying step reaches to be completed in the whole material, without remaining areas or pieces with high humidity that can not reach high temperatures by being shielded from the heat; (b) drying the whole material to be able to increase the combustion temperature of the solids from 800° C. to 1350° C.; (c) thermally annihilating the material, by means of a combustion in a refractory oven, either shredded or powdered and in suspension, to achieve the high required temperature to be reached and kept within the whole material; that there is an homogeneous oxygen concentration and that it can be sure that the time of treatment allows for getting the thermal annihilation; and (d) recovering the heat of combustion of the material, which should be carried out only after the total oxidation of the material, never during its combustion, for not allowing to decrease the temperature before the treatment of thermal annihilation has been completed.
