Abstract
Zero waste dosing method for filling containers of liquids which provides to use, at a delivery station of the liquid product, at least a volumetric pump with a rotor and stator, associated with a tank of the liquid to be introduced into said containers.
Claims14
A zero waste dosing method to fill containers of liquids which provides to use, at a delivery station of the liquid product, at least a volumetric pump with a rotor and stator, associated with a tank of the liquid to be introduced into said containers, comprising a step of filling each container, defining a “zero” angular start-of-delivery position of the volumetric pump and an angular end-of-delivery position of the desired quantity of liquid as a function of the “zero” angular position, wherein the “zero” angular position and/or the angular end-of-delivery position of the desired quantity of liquid are controlled and regulated by control and command means configured to re-position the “zero” angular position and/or the angular end-of-delivery position, said method providing to control, by means of selective interception of the liquid delivered downstream of the outlet pipe of the volumetric pump, the desired delivery quantity of the liquid by defining an end-of-cycle delivery transitory through the angular end-of-delivery position.
A zero waste dosing apparatus to fill containers of liquids comprising at least a tank of liquid hydraulically coupled to at least one volumetric pump, characterized in that at least one of said volumetric pumps is configured to define a “zero” angular start-of-delivery position associated with a determinate angular position of a rotor of the at least one volumetric pump with respect to a pumping chamber of the liquid provided between rotor and stator and to define an angular end-of-delivery position of the desired quantity of liquid, a delivery extra-travel being provided, not connected with the introduction of the liquid into the containers, said apparatus being operatively associated with control, testing and command means which condition the “zero” angular position and/or the angular end-of-delivery position.
