Abstract
The continuous treatment device (10) includes a tank (11) of elongated shape and that determines a mixing chamber (15) which includes, at a first end, at least one inlet orifice (12) for the raw material and, at a second end, at least one outlet orifice (13) for the treated material, and also, between these orifices, at least one agitator shaft (16) equipped with blades (17) suitable for continuously mixing and advancing the material in the mixing chamber (15) from the inlet orifice to the outlet orifice. The device also includes a mixing screw (25) in the bottom of the tank, which is positioned in the mixing chamber (15), below and parallel to the at least one shaft (16), and which is suitable for being rotated, about at least one direction of rotation, the opposite way from the advance of the material from the inlet orifice to the outlet orifice.
