Claims10
A liquid dropping system, comprising a liquid storage reservoir comprising a cylindrical storage area with a round base and a conical liquid outlet area, the conical liquid outlet area being provided with an outlet nozzle and a dropping hatch, characterised in that the liquid dropping system comprises means for varying an air pressure in the liquid storage reservoir depending on a level of a liquid in the liquid storage reservoir,
- the means for varying the air pressure in the reservoir comprising a pressurised air diffuser capable of distributing an air supply over a surface of the liquid and a pressure regulator acting on the air pressure in the reservoir,
- wherein said pressure regulator is also able to regulate a pressure of a liquid leaving the reservoir to be around a set value, and
- wherein the liquid dropping system comprises a control module acting on the pressure regulator and on the dropping hatch.
