Definitions

  • THIS INVENTION relates to an insert for use in an oven, and particularly but not necessarily domestic ovens.
  • the usual domestic electric or gas oven does not retain heat for very long, and is not able to maintain an accurate temperature for precision cooking.
  • An oven insert comprising a refractory material member having a base shaped to enable the member to be located in an oven and having a cooking surface on the opposite side to the base, the member being of a material selected to absorb and radiate heat to reduce variations in oven temperature.
  • he material to have a generally honeycombed internal structure, for the bulk density of the insert to be approximately 1200 kg per m 3 , and for the material to be foamed before firing to provide a honeycombed structure of a multiplicity of interspaced bubbles between the material.
  • the thermal conductivity of the insert is 0,4.W/M/C, and the weight of the insert is less than 8 kg.
  • the insert has the following constituents by weight percentage :
  • the balance of the material is preferably a raw material base of Chamote.
  • the oven insert prefferably has a metal plate for location against the base surface of the insert, which is planar.
  • the metal plate can be secured to the base of the insert, or have anchoring formations on one side which are embedded in the insert during moulding and firing of the insert material.
  • the metal plate can be glued to the base of the insert.
  • the metal plate prefferably has outwardly extending side flanges bent upwardly to accommodate the sides of the insert.
  • the refractory material is an alumino silicate, having the following constituents:
  • the balance of the material is made up by the raw material base of Chamotte
  • the material is fired, and has a conductivity of 0,4W/M/°C, with a bulk density of 1200 kg/M 2 .
  • the bulk density is relatively low owing to the foamed nature of the product, and this assists with physical handling of the product both in use and during storage and delivery.
  • the cold crushing strength of the material remains constant at approximately 40MPa between 50 and 550° C whereafter it declines before increasing.
  • the base surface (10) of a refractory insert position (11) of which is shown, has a metal base plate (12) fitted flush against it.
  • the base plate (12) covers the full extent of the base surface, and allows for greater transference of heat from a heat source to the plate into the insert itself.
  • the insert has metal anchoring strips (13) punched out of it to leave slots (14), and the metal plate is located in the bottom of the mould so that the bent anchoring strips (13) are moulded into the bottom of the insert.
  • the base plate is thus permanently secured.
  • Such a base plate may alternatively be glued in position with a suitable glue.
  • an insert (20) is shown of the same shape of the insert described with reference to Figure 1, having an upper bevelled edge (21), but being located in a metal tray (22) which has a bottom (23) covering the entire base surface (24) of the insert (20).
  • the bottom of the tray provides the base plate, but the tray has sides (25) which slope upwardly to follow the lower bevelled edge of the insert accurately, to assist in locating the insert in the tray.
  • the insert In use, the insert is located in an oven such as a domestic oven on the bottom grid and the oven is heated up to approximately 220° C, typically for baking pizzas. When the oven has reached the required temperature the pizza dough is located on the top and cooked for approximately 4 to 5 minutes prefereably with the griller element of the oven on as well. It has been found in practice that the insert operates to good effect for particularly cooking pasta type dishes requiring intense heat of short duration. It is believed that the bevelled sides of the insert assist in allowing heat from the bottom of the oven to circulate more effectively around the insert and provide a heat radiation effect passing round the sides of the inserts into the top of the oven, as in the conventional domed pizza oven. Preferably the degree of bevel to the horizontal on the acute angle side, is 52°.
