  • Publication number: 20150305554
    Abstract: Two-sided grills are provided having a positively controlled vertical gap between two opposed cooking surfaces, means for detecting initial contact of an upper cooking surface on a food item placed on a lower cooking surface, means for measuring the gap between the cooking surfaces at the initial contact position to determine a thickness of the food item and a food-item type, and a control system for automatically initiating a pre-programmed cooking routine based on the food-item type. The cooking routine includes varying the gap dimension between the platens while cooking the food item, the range or sequence of gap dimension variation being based on either the measured thickness of the food item or a nominal thickness associated with the identified food item type. In other aspect, grills according to the invention may include a lower platen mounted for vertical movement and an upper platen mounted only for pivoting.

  • Patent number: 8850969
    Abstract: An device and method are provided for steam injection heating to melt a cheese component of a food item of a food product. The device includes a housing for a steam generator and a steaming chamber. Generated steam is injected into the steaming chamber to melt the cheese component of the food item held in a container inserted into the steaming chamber. The device is configured to rest on a counter so that the counter provides an interior support surface in the steaming chamber. The counter also provides an exterior support surface for the container and a work surface. The container is inserted into the steaming chamber by sliding it on the exterior surface and is received and supported by the interior support surface. A food product having a melted cheese component is assembled, produced and packaged while the container is supported in the single plane of the counter.

  • Publication number: 20140272060
    Abstract: A commercial cooking apparatus is provided for simultaneous steaming and two-sided grilling of food items having non-uniform thickness and/or variations in nominal thickness. The apparatus includes a compressible, heat-resistant ring member, and optionally a flexible, non-stick, heat-resistant film material associated with the ring member to form a cavity defined by the inner perimeter of the ring member. A cooking method is also disclosed, wherein a food item and a quantity of water are introduced into the cavity, and the food item is simultaneously cooked by the heated upper and lower platens of a conventional clamshell grill or similar apparatus and by steam generated by heating the water.

  • Patent number: 8770433
    Abstract: A tray for vibratory conveying of food articles from a hopper is provided. The tray includes a tray body, food inlet portion, and a food outlet portion. An upwardly extending dividing member divides the tray into at least two food inlet conveyor passageways, the inlet conveyor passageways merging into a single food passageway that extends to the food outlet portion. The single food passageway may have an initially wide portion and subsequently narrow to a narrow portion as it approaches a discharge end. This arrangement helps to declump food items, preferably causing food items the size of chicken nuggets to be conveyed in a single-file arrangement along the single food passageway. The single food passageway is preferably non-linear, and may, for example, have a zigzag or serpentine configuration to promote accurate dispensing of food items.

  • Patent number: 8684600
    Abstract: A method is provided for storing a cooked food in a flexible-walled container having an opening. The method includes placing a quantity of food in a flexible-walled container and submerging at least a portion of the container in a liquid with the opening being located so that liquid does not enter the opening. At least the lower portion of the container is maintained in the liquid and the food is maintained in the container below the surface of the liquid. The liquid collapses the container to seal the container. The temperature of the liquid may be maintained at a non-ambient temperature to heat or cool the food as it is stored. The method may also include storing the food adjacent a work surface, or at a remote main vat and transporting the rack to the work surface at which a serving that includes the food is prepared.

  • Patent number: 8251327
    Abstract: A container holder adapted to hold a container between two spaced apart prongs is provided herein. The prongs clamp the container with a clamping force large enough to hold the container, but small enough to avoid damaging the container. The prongs may be spaced apart to fit different-sized containers, while the clamping force still meets these criteria. The clamping force may be provided by a substantially constant-force spring or a variable-force spring. In a method according to the present invention, a stack of nested containers is held in a container holder as described, for subsequent removal of a selected container from the stack.
