ENERGY EFFICIENT OPEN PASS THROUGH HOLDING DEVICE
A holding device for food products, comprising: a base unit comprising a heating element and a top surface disposed above the heating element, wherein the food products are disposed on the top surface of the base unit; a top portion disposed apart from and above the top surface of the base unit, such that the food products can be disposed between the base unit and the top portion, wherein the top portion comprises at least one selected from the group consisting of: (1) an electrically conductive coating disposed on a bottom surface of the top portion which radiates heat toward the food products, (2) a low emissivity coating on a top surface of the top portion, and (3) downwardly pointing edge portions which extend beyond the dimensions of the base unit, thereby providing for convection capture of heat generated from the base unit as it rises and contacts the top portion; and at least one support post, wherein the support post supports the top portion above the base and provides a conduit or other means by which electrical connectivity is established between the base and the top portion. Alternatively, electrical connectivity may be established at the base of the device. The base may be divided into regions, one or more of which may be independently temperature-controlled.
1 . A holding device for food products, comprising:
a base comprising a heating element and a top surface, wherein the food products are on the top surface of the base;
a canopy above the top surface of the base, such that the food products can be between the base unit and the canopy, wherein the canopy comprises an electrically conductive coating on a bottom surface of the canopy, which radiates heat toward the base; and
at least one support post, wherein the support post supports the canopy above the base.
2 . The holding device according to claim 1 , further comprising a low emissivity coating on a top surface of the canopy.
3 . The holding device according to claim 1 , wherein the base comprises a heated mat on the top surface.
4 . The holding device according to claim 3 , wherein the heating element is electrically connected to a bottom side of the heated mat.
5 . The holding device according to claim 3 , wherein the heated mat is made of a conductive material.
6 . The holding device according to claim 1 , further comprising a power source in the base, and wherein the power source is in electrical communication with the conductive coating of the canopy through electrical connections in the one or more support posts.
7 . The holding device according to claim 1 , wherein the canopy comprises a translucent, transparent or opaque material.
8 . The holding device according to claim 1 , wherein the canopy comprises downwardly pointing edge portions, thereby directing heat from the canopy towards the food products.
9 . The holding device according to claim 1 , wherein the canopy comprises one or more rotatable edge portions.
10 . The holding device according to claim 1 , further comprising at least one support post at a side edge of the base.
11 . The holding device according to claim 1 , wherein the canopy is electrically connected to the base via the at least one support post.
12 . The holding device according to claim 1 , wherein the at least one support rail is a plurality of support posts.
13 . The holding device according to claim 8 , further comprising a hinged flap on the at least one downwardly pointing edge portions.
14 . The holding device according to claim 1 , wherein the base is divided into one or more sections with a partition therebetween.
15 . A holding device for food products, comprising:
a base comprising a heating element and a top surface above the heating element, wherein the food products are on the top surface;
a canopy apart from and above the top surface of the base unit, such that the food products are between the base and the canopy, wherein the canopy comprises a low emissivity coating on a top surface of the canopy; and
at least one support post, wherein the support post supports the canopy above the base.
16 . A holding device for food products, comprising:
a base comprising a heating element and a top surface, wherein the food products are on the top surface of the base unit;
a canopy apart from and above the top surface of the base unit, such that the food products are between the base unit and the canopy, wherein the canopy comprises downwardly pointing edge portions which extend beyond the dimensions of the base unit, thereby providing for convection capture of heat generated from the base unit as it rises and contacts the canopy; and
at least one support post, wherein the support post supports the canopy above the base.
