1. A method of molding food patties comprising the following steps performed in a repeating mold cycle:

  • moving a mold plate having a mold cavity of given surface area from a fill position to a discharge position and back to the fill position, with a fill dwell interval at the fill position;

    pumping a moldable food product from a food product supply directly into the mold cavity, under a given maximum fill pressure, through a fill passage having a cross-sectional area immediately adjacent to the mold plate fill position effectively encompassing substantially the entire surface area of the mold cavity, during a portion of the mold plate cycle including the fill dwell interval;

    maintaining an intermediate pressure on the food product in the fill passage, comprising no more than a minor fraction of the fill pressure, during a major portion of the transition interval in each mold cycle in which the mold plate moves away from its fill position but a part of the mold cavity remains in communication with the fill passage; and

    restricting the pressure on the food product in the fill passage to the intermediate pressure or less during the balance of the mold plate cycle, comprising at least about half of that cycle.
