  • Patent number: 7717030
    Abstract: A mold form fryer utilizing a top conveyor that transports snack pieces through a constant velocity oil stream without the need for a bottom mating mold or conveyor. Herein, the form fryer is provided with a top conveyor disposed above a fryer oil pan positioned longitudinally through the fryer. Uncooked snack pieces are provided to the fryer oil pan by a bottom entrance conveyor. Snack pieces, once in oil within the fryer, meet with a top conveyor having convex molding surfaces with product-centering elements. At the exit portion of the fryer, a bottom exit conveyor receives the cooked snack pieces from the top conveyor. As no continuous bottom conveyor is utilized, the fryer oil pan may be provided with a reduced volume segment situated between the bottom entrance and exit conveyors.

As no continuous bottom conveyor is utilized, the fryer oil pan may be provided with a reduced volume segment situated between the bottom entrance and exit conveyors. Additionally, the molding surfaces may be selected to produce uniformly shaped snack pieces that are either convexly or concavely shaped when viewed upon the bottom exit conveyor.

  • Publication number: 20040028800
    Abstract: Snack food products, such as potato crisps or chips, are fabricated from dough that is processed into uncooked snack chips for cooking in a form fryer. Form fryers utilize conveyors that generally employ metal that contacts and retains the snack chips while being passed through an oil bath for frying. With the use of anti-sticking agent such as lecithin, the conveyors of the fryer do not need to be cooled prior to contacting the uncooked chips. The anti-sticking agent prevents the chip from adhering to the metal surfaces of a fryer conveyor that would otherwise cause a chip without anti-sticking agent to adhere thereto.

  • Patent number: 5643626
    Abstract: Potato chips having hardbite texture and flavor characteristics of kettle-fried potato chips are produced in an apparatus comprising a fry kettle with cooking oil circulation and heat transfer means. Production efficiency is greatly increased over conventional batch preparation of kettle-style chips; batch size is significantly increased and total fry time is advantageously decreased. In certain embodiments the batchwise preparation process includes the step of selecting texture-setting potato slice dehydration rate conditions for at least a segment of the frying time, which ends before the moisture content of the slices is reduced to about 45% by weight or less. Selecting appropriate dehydration rate conditions enables the production of potato chips of a variety of textural characteristics over varying cooking oil time/temperature profiles.
