    • A machine for molding hamburger patties and other similar food patties, of the kind incorporating a vacuum-intake plunger-type food pump that pumps food product from a supply hopper into mold cavities in a reciprocating mold plate, is equipped with a hydraulic drive system that drives both the food pump and a pair of feed screws that impel the food product toward the pump intake. The feed screws axes are approximately parallel to the direction of travel of the plunger and the outlet end of the feed screws is enclosed to preclude reverse movement of food product from the food pump into the supply hopper at the beginning of the pumping stroke; rotation of the feed screws is timed to coincide with the intake stroke of the pump in an arrangement that can be made to compensate for variations in pumped volume of the food product. A single hydraulic pump provides both a low-pressure hydraulic supply for plunger advance and a high-pressure hydraulic supply for plunger retraction and feed screw rotation. One electric motor powers both the hydraulic pump and a mechanical drive for the mold plate.
    • 一种用于模制汉堡包馅饼和其他类似食品馅饼的机器,其中装有一个液压驱动系统,该真空吸入柱塞式食品泵将食品从供料斗向往复式模板中的模腔中抽出, 驱动食物泵和一对将食品推向泵入口的进料螺杆。 进料螺杆轴线大致平行于柱塞的行进方向,并且进料螺杆的出口端被封闭,以防止在泵送冲程开始时食品从食品泵反向运动到供料斗中; 进给螺杆的旋转被定时以与泵的进气冲程一致,该排列可以被制成以补偿食品的泵送体积的变化。 单个液压泵提供用于柱塞前进的低压液压供应和用于柱塞缩回和进给螺杆旋转的高压液压供应。 一台电动机为液压泵和模具板的机械驱动器供电。
