Patent number: 12185872Abstract: A steam chamber has enhanced planarity of its cooking surface, and a method for making the same via friction welding is provided. An array of stays within the steam chamber are friction welded to the undersurface of the upper plate, opposite the cooking surface, thus minimizing the heat affected zone and distortion of the cooking surface as compared, for example, to arc welding. A lower plate includes an array of holes sized and configured to be engaged by the array of stays, and is then welded to the array of stays via plug welds or rosette welds at the hole/stay junction. The resulting steam chamber preserves a high level of planarity in the cooking surface, while allowing the use of a relatively thin top plate for thermal and cooking efficiency.Type: GrantFiled: June 7, 2021Date of Patent: January 7, 2025Assignee: AccuTemp Products, Inc.Inventors: Lawrence P.

Patent number: 11700967Abstract: A method and apparatus for filling a steam chamber. In one exemplary embodiment, a steam chamber is placed in selective communication with a vacuum pump and a heat transfer medium, such as a source of deaerated water. The steam chamber is then placed in communication with the vacuum pump, which draws a vacuum on the steam chamber and begins removing air from the interior thereof. Once a sufficient vacuum has been drawn on the steam chamber and substantially all of the air removed therefrom, the steam chamber may be placed in communication with the heat transfer medium. In one exemplary embodiment, the heat transfer medium is deaerated water. A predetermined amount of heat transfer medium is then allowed to fill the steam chamber. Once the predetermined amount of deaerated water has been received within the steam chamber, a steam chamber may be sealed.Type: GrantFiled: March 21, 2016Date of Patent: July 18, 2023Assignee: AccuTemp Products, Inc.Inventors: Larry R.

Patent number: 10955281Abstract: An improved fluid level sensor includes a radially magnetized magnet integrated into a float, and a Hall sensor adapted to monitor the magnet field emitted from the magnet. This arrangement provides a continuously variable signal across a range of travel, such that a controller receiving the signal can produce precise fluid level measurements and detect operational states of an associated device based on fluid behavior. In addition, the present fluid level sensor is suitable for use in harsh service environments, both because it is physically resilient to fouling, and because the controller is capable of detecting fouling by sensor behavior. In the context of a steam cooker, the present fluid level sensor can also sense low-water, overfill and fouling conditions, while remaining relatively insensitive to food residue, water scale buildup, corrosion and foaming.Type: GrantFiled: May 17, 2018Date of Patent: March 23, 2021Assignee: AccuTemp Products, Inc.Inventors: Lawrence P.
