Heat-resistant tray particularly for food products as well as an oven for use in the heating thereof
By, according to the invention, producing a food product tray ( 1 ) with a lid ( 2 ) using a basic material ( 3 ) such as aluminum, and providing said material ( 3 ) with a coating ( 4 ) comprising at least two layers ( 9 and 10 ), of which at least one of the materials has a high emission value, it is possible with a suitable dimensioning and placement of the coating ( 4 ) on the inner and/or outer side of the tray ( 1 ) and the lid ( 2 ) to obtain a hitherto unknown precise heating of the individual food products within the same heating time in an oven ( 12 ). The oven ( 12 ) has heating elements ( 14 - 16 ) which may abut against the sides and bottom of the tray as well as against the lid ( 2 ), said heating elements ( 14 - 16 ) may have a zonal heat emission in order to obtain the best possible cooking of the food. A QR code ( 20 ) on the lid ( 2 ) readable by the oven ( 12 ) allows for programming the oven with a view to both heat exposure intensity and position of the heat exposure in relation to the food products ( 6 A and 7 A) in the tray ( 1 ).
1. A system comprising:
a heat-resistant tray;
a removable lid configured to cover the heat-resistant tray;
the heat-resistant tray comprising one or more compartments, and configured to partly store food products and partly heat food products in an oven, wherein the oven comprises heat-producing contact elements, where at least one of the heat-producing contact elements is an upper contact element configured to abut an outer surface of the removable lid and comprising penetrating means to form steam outlet openings in the heat resistant lid; and
wherein the heat-resistant tray and the removable lid are at least partially covered on the inner and/or outer surfaces with a coating with a high emission value, a high refractive index, or a combination thereof.
