System comprising a static microdoser for introducing an additive into a container

A system for introducing an additive into a container partially filled with a main liquid material, the system comprising an automated conveyor for transporting the container along a straight horizontal trajectory (T) at a substantially constant container speed (Vc),

• the system further comprising a static microdoser having a nozzle from which at least one jet of an additive issues upon passage of an opening of the container in proximity to the nozzle to introduce the additive into said container,
• wherein the nozzle of the microdoser is inclined relative to a vertical direction that is perpendicular to the trajectory (T),
• wherein the system is configured to introduce a given quantity of additive into the container, said quantity having a mass (m),
• the at least one jet hits a free surface of the main liquid material at a relative impact speed (V), over an area A of said free surface of the main liquid material;
• and
• the system is configured, with regard to the inclination of the nozzle, to the number, the shape and the speed (Vj) of the at least one jet, to the mass (m), and to the container speed (Vc), such that
• the specific kinetic energy (I) of the impact of the at least one jet on the free surface of the main liquid material, defined by the formula:
