1. An automatic hybrid volumetric method of fluid ingredient dispensing for a mixture, according to pre-selected formulations, utilizing a supply of the fluid ingredients, an ingredient container, a power-driven plunger in the ingredient container, the plunger movable to expel fluid in the ingredient container, a mixture container, and a calibration weight scale, the method comprising the steps of:

  • connecting the ingredient container to the supply to receive a first ingredient in the ingredient container;

    connecting the ingredient container to the mixture container for the mixture container to receive ingredient expelled from the ingredient container by movement of the plunger;

    calibrating the method by powering the plunger to move in the ingredient container a controlled distance, to expel ingredient to the mixture container, while weighing the increase in the weight of the mixture container, resulting in a calculated rate of weight dispensed per increment of movement of the plunger; and

    dispensing the ingredients required by the formulations in the weight amounts required by the formulations from the supply through the ingredient container to the mixture container, through calibrated movements of the plunger in the ingredient container.
