Abstract
A microwave susceptor having projections such as linear ridges which define circulation channels such as linear grooves. The susceptor may include apertures at the ridge apexes and the groove nadirs for allowing food secretions such as grease and steam, to pass through the susceptor. A strut may be releasably coupled to the susceptor for increasing the structural integrity of the susceptor.
Claims3
A microwave susceptor comprising a sheet of microwave interactive material adapted for converting microwave energy to heat, said sheet having a multiplicity of alternating substantially parallel ridge apexes and groove nadirs, said ridge apexes adapted for supporting a food item thereon, said sheet adapted for increasing and decreasing the linear distance between sequential ridge apexes by compressing or expanding the pleated sheet.
A microwavable container for food comprising:
- a) a microwave transparent material defining a chamber;
- b) a microwave susceptor retained within said chamber which comprises a substantially uniformly pleated sheet of microwave interactive material adapted for converting microwave energy to heat and having a plurality of substantially parallel linear ridge apexes, said sheet adapted to concentrate the heat generation capacity of the susceptor when said pleated sheet is compressed, and to dissipate the heat generation capacity of the susceptor when said pleated sheet is expanded, and
- c) a food item retained within the chamber and supported by the ridge apexes of the microwave susceptor.
A microwave susceptor comprising a substantially uniformly pleated sheet of microwave interactive material adapted for converting microwave energy to heat and for supporting a food item thereon, said sheet generally adapted to concentrate the heat generation capacity of the susceptor when said pleated sheet is compressed and to dissipate the heat generation capacity of the susceptor when said pleated sheet is expanded.
