Abstract: A method for cooking food includes heating a liquid cooking medium in a cooking vessel having a “U”-shaped structure having a height is sufficient, with sufficient medium added, to attain a hydrostatic pressure at a predetermined lower depth that is substantially greater than ambient atmospheric pressure. The food is conveyed through the vessel, mostly cooking at the bottom, where the hydrostatic pressure facilitates a cooking of the food at a rate substantially greater than a rate at ambient pressure. A further aspect of the invention is a method for reducing wastewater output and makeup water usage when cooking a food containing a complex carbohydrate. This method causes released complex carbohydrate to cause a lower viscosity increase than at ambient pressure, thereby increasing a cooking effectiveness of the water and reducing a need for adding makeup water and disposing of wastewater.

Abstract: A method for treating used cooking liquid from a cooking process includes the steps of removing a portion of the used liquid cooking medium from a cooking vessel and channeling it to a treatment vessel. The treatment vessel is sealable against a pressure that is substantially greater than atmospheric pressure. The cooking medium in the treatment vessel is then subjected to a pressure substantially greater than ambient atmospheric pressure, and it is heated in the treatment vessel to a temperature greater than an atmospheric pressure boiling point for a sufficient time to restore the cooking medium to a condition suitable for cooking. Finally the treated cooking medium is returned to the cooking vessel from the treatment vessel. This method is environmentally useful for significantly reducing wastewater production and “makeup” water usage.

Abstract: An apparatus for cutting dry pasta strands includes a frame and a guide rail mounted to the frame. A bucket is slidably mounted to the guide rail and linearly moves along the guide rail. The bucket has a stepped pasta-receiving channel including a cutting edge. A cutting blade is fixed to the frame for selective sliding engagement against the cutting edge to cut the pasta in half.
