  • Patent number: 7029261
    Abstract: A dough divider including a hopper with a lid, latch assembly and press plate. The lid has an open and closed position. The latch assembly is adapted to maintain the lid in the closed position when activated and to discontinue maintaining the lid in the closed position when deactivated. The press plate is vertically slidable within the hopper, with the hopper being adapted to accept dough between the lid and the press plate. The press plate is adapted to be driven towards the lid in order to compress the dough between the press plate and the lid within the hopper. The latch assembly is automatically activated to maintain the lid in the closed position while the press plate is being driven towards the lid. The latch assembly is automatically deactivated to discontinue maintaining the lid in the closed position after the dough has been compressed and divided within the hopper.

  • Patent number: 6658995
    Abstract: A proofer includes an enclosure defining a chamber. An air circulation system includes a passageway having an air inlet and an air outlet connected to the chamber. A first fan pulls air into the air inlet from the chamber, and expels air from the outlet into the chamber. A fluid reservoir is positioned adjacent the air circulation system, such that air contacting fluid in the reservoir upon actuation of the first fan is humidified. A heating element heats fluid in the fluid reservoir, and a second fan flows air over at least a portion of the reservoir outside the chamber and cools fluid in the reservoir. A controller selectively actuates the heating element and the second fan based upon the temperature and/or humidity in the chamber to control the temperature of the fluid in the reservoir and thereby reduce fluctuations in temperature and humidity within the chamber.

  • Patent number: 6499271
    Abstract: A container and lid sealing apparatus comprising a frame structure including a sealing position, support beams, a shiftable container support which includes a container retainer and shiftable on drawer rails from a position for loading and unloading a container into and out of the retainer, to the sealing position for sealing a lid on the tray, an upper heater platen suspended above the tray support, and an actuator actuable to force the upper heater platen downwardly with force onto a container and lid on the support. The force is equally distributed on all portions of the platen to seal a lid onto a container. The actuator may be either a manual actuator or an air actuator. The actuator is multi-axially pivotally coupled to the platen to thereby allow the platen to rock and seek and obtain a parallel relation with the container flange and lid.

  • Patent number: 6431848
    Abstract: A dough divider including a hopper with a lid and a press plate vertically slidable within the hopper. The hopper is adapted to accept dough between the lid and the press plate, and the press plate is adapted to move towards the lid in order to compress the dough between the press plate and the lid within the hopper. The dough divider further includes a two part pressure relief system including a reversible cylinder assembly and at least one pressure relief opening. The reversible cylinder assembly is connected to the press plate and adapted to move downward in order to allow the press plate to move towards a bottom of the hopper when pressure applied to a top of the press plate from the dough within the hopper reaches a predetermined level. The pressure relief opening is adapted to relieve pressure within the hopper between the press plate and the lid by allowing the dough to escape from the hopper through the pressure relief opening when the press plate has reached the bottom of the hopper.

  • Patent number: 5613423
    Abstract: A food cooker/rethermalizer especially suited for cooking or for reheating of prepared, packaged meat and sauce entree items, and optionally for cooking vegetables. The apparatus includes a multiple of food item receiving locations defined by a locator rack, and fluid ejecting tubes beneath the locations to eject fluid such as air therefrom, which rises over the package surfaces for bath mixing and efficient and uniform heat transfer. The tubes include a pair of upwardly sloped conduits oriented in opposite directions and which eject fluid at the upper ends of the tubes, on opposite sides of the bath, to cause circulation of the heated liquid bath. The bath is heated by resistance coils embedded in rubber bonded to the outside of the vessel. The bath level is controlled by a dual temperature sensor device, one sensor above the other, to detect a predetermined temperature differential and activate a water supply valve to inject only small quantities of water.
