Abstract
The condensation-free and bacteria-free pan system provides hygienic cover for a food preparation area. The system includes at least one pan having a top cover sheet, a heating element, a layer of thermal insulation and a bottom pan sheet. The top cover sheet is formed from a corrosion resistant material and is adapted for catching contaminants falling from overhead. The layer of thermal insulation is sandwiched between the top cover sheet and the heating element, and the bottom pan sheet is formed from a thermally conductive, corrosion resistant material, the bottom pan sheet having a lower wall and at least one sidewall. The top cover sheet, the layer of thermal insulation and the heating element are disposed above the bottom pan sheet to form a multilayer pan.
Claims20
A condensation-free and bacteria-free pan system, comprising:
- at least one pan having multiple layers, including:
- a top cover sheet adapted for catching contaminants falling from overhead;
- a layer of thermal insulation positioned below the top cover sheet;
- a heating element positioned below the layer of thermal insulation;
- and
- a bottom pan sheet made of thermally conductive material, bottom pan sheet having a lower wall and at least one sidewall, the top cover sheet, the layer of thermal insulation, the heating element, and the bottom pan sheet being joined together to form the pan;
- and
- a controller electrically connected to the heating element for randomly heating the at least one pan to eliminate bacteria and reduce condensation collecting on the bottom pan sheet when the pan is mounted above a work area.
A condensation-free and bacteria-free pan system, comprising:
- a plurality of interlocking multilayer pans, each of the pans having:
- a bottom pan sheet having a flat floor made of thermally conductive material and peripheral sidewalls surrounding the floor, the peripheral sidewalls including a mounting sidewall adapted for attaching the pan to a vertical support surface between an overhead structure and a work area with the pan sloping downward away from the support surface, a J-shaped sidewall forming a trough opposite the mounting sidewall, and opposing connector sidewalls connecting the mounting sidewall with the J-shaped sidewall;
- an electrical heating element disposed on the floor of the bottom pan sheet;
- a layer of thermal insulation disposed on the heating element;
- and
- a top cover sheet disposed on the layer of thermal insulation, the
- top cover sheet forming a drip pan to convey contaminants dripping from the overhead structure to the trough to protect the work area, the layer of thermal insulation insulating the top cover sheet from the heating element to keep the top cover sheet at room temperature;
- and
- a controller electrically connected to the heating element of each of the pans, the controller being programmed to periodically turn the heating element on to heat the bottom pan sheet to a programmable temperature to kill microorganisms and evaporate condensation rising from the work area to the pans;
- a plurality of drip drains, each of the pans having one of the drip drains depending therefrom;
- and
- a common drip line forming a single conduit, each of the drip drains emptying into the drip line, the drip line carrying contaminants collecting in the trough away from the work area below the plurality of interlocking pans.
