  • Patent number: 6953004
    Abstract: Seasoning for use with snack chips can be recovered and recycled. A seasoning permeable conveyor transports snack chips through a seasoning application. The seasoning applicator deposits seasoning onto the snack chips. The conveyor allows the seasoning not adhered to the moving snack chips to substantially pass through and by toward a seasoning recoverer. The seasoning recoverer, which is positioned beneath the conveyor, collects the seasoning for purification and blending with fresh seasoning. After blending, the seasoning mixture is transported to the seasoning application for use.

  • Patent number: 6893673
    Abstract: An improved method for controlling blister formation in fabricated, expanded snack products by utilizing discrete, solid lipid particles. These lipids must be solid at room temperature with a melting point above 100° F. such that they remain discrete and solid when mixed with the dough and are subsequently sheeted or extruded. During the toasting, frying, or baking step, the solid, lipid particles melt and soften and disrupt the starch matrix, thus allowing steam to escape and preventing blisters. The blisters are only prevented, however, in the localized area where a solid, lipid particle exists. Thus, by changing the level of solid, lipid particles in the dough, the size of resulting blisters can be controlled.

  • Patent number: 6797213
    Abstract: A method and apparatus for cutting a puff extrudate utilizing a blade that passes through the extrudate while the extrudate is in a viscous melt stage. The present invention utilizes a tube to facilitate production of a curly puff extrudate. A gap is provided in between the tube and the extruder die to allow a blade to access the extrudate as it exits an orifice in the die. The blade accesses the extrudate at the viscous melt stage, before the extrudate has cooled and hardened. The blade nicks the extrudate, as opposed to completely cutting it, which allows the extrudate to remain connected throughout processing such as curling in the containment tube. The gap also allows steam to be vented form the extrudate as it exits the orifice in the die. The nicked extrudate separates when fried or baked.

  • Patent number: 6770233
    Abstract: An improved method of applying a controlled pressure to the flapper in a curly puff production apparatus. The present invention uses a pneumatic system to apply a pressure to a flapper. The invention utilizes a rotary actuator that applies a near constant pressure to the flapper. Alternatively, a pair of telescoping tubes connected to the flapper and an air pressure source can apply a near constant pressure to either the proximate end or the distal end of the flapper. Further in the alternative, a linear actuator can be used to provide a near constant pressure to the flapper. As a result of applying a constant pressure to the flapper, the pitch in the curls of the curly puff extrudate can be more predictably controlled.

  • Patent number: 6746743
    Abstract: A flexible container with a wall structure comprised of multi-layer, flexible thin films, including a first film layer that is affixed to the wall structure by a releasable adherence and that incorporates a removable promotional piece. The removable promotional piece is incorporated into the first film layer such that, other than a continuous cut facilitating removal and any conspicuous printing on the removable portion, it is indistinguishable from the rest of the exterior of the package. The continuous cut allows for full detachment of the removable portion from the first film layer so that only the releasable adherence prevents it from separating from the container. The promotional piece is removed by peeling it away from the container, where the peeling is facilitated by the action of the continuous cut and releasable adherence. The removable piece may function as a gaming piece or redeemable coupon, or may be designed to retain a tacky surface and function as a sticker.

  • Patent number: 6728770
    Abstract: An apparatus and method for workload balancing along multiple communication paths to a plurality of devices. The apparatus includes a controller that accumulates path usage information and a path balancing device that makes use of the accumulated path usage information to perform a path balancing operation. The path balancing method involves the path balancing device calculating the total expected connect time for all I/O messages issued to each of a plurality of peripheral devices during a predefined sampling period. These totals are then added for each communication path for the sampling period to obtain path totals. The path totals are then compared to see if a difference between the highest used path and the lowest used path is greater than a threshold amount. If the difference is higher than the threshold amount, the peripheral device having a total expected connect time that is closest to a target value is moved from the highest used path to the lowest used path.
