  • Patent number: 6881050
    Abstract: A forming apparatus to produce nonsymmetrical three-dimensional shaped products from a food extrusion device includes a vector drive controlling an induction motor through current flux control, which selectively actuates an iris diaphragm. Food product is pumped to the diaphragm, which shapes the product in accordance with settings from an encoder. The flux drive permits variable control of the diaphragm motor in segments of a 360° revolution. Alternatively, a servo drive may be used to drive a synchronous motor to operate in accordance with instructions from an encoder-shaping product from a food pump as it is forced through the diaphragm.

  • Patent number: 6640848
    Abstract: An apparatus for the portioning and depositing of food products in form/fill/seal machines and other food packaging machinery into pockets that are then evacuated and sealed. A food pump outlet is connected to a manifold which has a number of outlets corresponding to positions over the pockets. A cutoff knife blocks the flow from each outlet. A programmable logic controller activates a first knife causing it to open with a single accurate portion of food product being pumped through the outlet and then cut cleanly by the knife. The operation continues for the remaining pockets which are provided with a single distinct and accurate portion for each pocket. Optionally, a double cut operation may be programmed into the logic controller. Once the pockets are full, the controller signals the packaging machine to index.
