  • Publication number: 20170290361
    Abstract: Method for continuously making kettle style potato chips. A continuous cooking process is disclosed without regard or need to mimic the U-shaped temperature-time profile typically used to create kettle-style fried potato chips. Potato slices are placed directly into hot oil of a single continuous fryer having multiple temperature zones, with no flume frying prior to placement therein and without regard to a monolayer arrangement. Cool oil from the end of the continuous fryer to the upstream portion of the fryer ensures continuous achievement of an initial low temperature profile, lower than that of previous methods. A further dip in temperature profile is achieved as water evaporates from the slices. The potato slices are then further fried in the downstream portion of the fryer in one or more regions having increased hot oil temperatures, which occur through the injecting of hot oil into the downstream portions.

  • Patent number: 8124160
    Abstract: A process and apparatus for a method for reducing the amount of acrylamide in thermally processed foods. This invention permits the production of foods having significantly reduced levels of acrylamide. The method relies on the manipulation of various unit operations used in the production of food products, particularly the washing and cooking unit operations. For example, the washing unit operation can be modified to provide a contacting step at an increased time and temperature, and adding components such as calcium chloride and L-cysteine to an aqueous solution used for the contacting. The cooking unit operation can be modified by dividing it into at least a higher-temperature first heating step and a lower-temperature second heating step in order to avoid the high-temperature/low-moisture conditions most favorable for acrylamide formation.

  • Patent number: 7303777
    Abstract: A continuous cooking process is disclosed that mimics the U-shaped temperature-time profile produced by a batch kettle fried potato chip operation. Potato slices are placed into hot oil in a flume portion of a continuous fryer. The potato slices exit the flume into an upstream portion of the fryer. Cooling oil is injected to the upstream portion of the continuous fryer to continuously achieve the trough portion of the U-shaped temperature-time profile. The potato slices are then further fried in the downstream portion of the fryer in a region having an increased hot oil temperature. The increased hot oil temperature occurs by injecting hot oil into the downstream portion. The temperature of injected hot oil can be controlled by the exit moisture content of the potato slices.

  • Patent number: 7156642
    Abstract: An improved dough-rolling apparatus and method for rolling sheeted dough. The proposed invention comprises a dough-rolling apparatus having a dough sheeter, a sheeting conveyor having a ramped section, a roll-initiating curtain positioned above the ramped section, and a roll-completing curtain positioned above the conveyor and downstream from the roll-initiating conveyor. Sheeted and cut dough pieces are deposited onto a steel mesh, partially-ramped sheeter belt, where two wire-mesh rolling curtains are draped onto the sheeter belt to induce rolling of the dough pieces.

  • Patent number: 7134543
    Abstract: A containment apparatus for a multi-pass oven consisting of guide rails and tapered guide chutes having side rails. A tapered guide chute directs product pieces from one conveyor to the center of a receiving region of an underlying conveyor. Guide rails are placed along the sides of the receiving region of an underlying conveyor and maintain baking product pieces on the conveyor. Diverters on the distal end of each guide rail further move product pieces toward the center of the conveyor. Such diverters help ensure that pieces reach a subsequent guide chute or subsequent conveyor without falling off of the conveyor. Such guide rails, diverters, and guide chutes help prevent damage to, and loss of, product pieces while pieces pass through the oven. Guide rails, diverters, and guide chutes are particularly effective at maintaining round or cylindrical pieces within a multi-pass oven.
