  • Figure 6 is a perspective view of a further different embodiment of the first portion of the baking tray.
  • the baking tray 1 for microwave ovens according to the present invention is designed for cooking in particular pastry and dough products, such as specifically pizza.
  • the baking tray 1 comprises a body 2 made of a refractory material and having a support surface S for a food product. More in detail the refractory material of the body 2 has a low susceptance, being substantially transparent to microwave radiations and it is selected in order to have high specific heat capacity and low thermal conductivity. According to an embodiment of the baking tray, the refractory material of the body 2 is porcelain or, more generally, a ceramic or a stone material. In particular cordierite is a suitable refractory material for the body 2, having a high thermal shock resistance, so that it allows the tray 1 to undergo rapid temperature variations without getting damaged.

  • the refractory material of the matrix has a low susceptance and it is substantially transparent to microwaves.
  • Suitable materials for the matrix of the composite material are for instance kaolin, cordierite or cement, although other materials having the above mentioned properties might be used without departing from the scope of protection of the present invention.
  • the susceptor material dispersed in particles within the matrix is for instance a metal, a metal oxide or a metal based material.
  • the susceptor material is iron or an iron compound, such as magnetite (Fe 3 O 4 ) or hematite (Fe 2 O 3 ).
  • the composite material is arranged within the body in a plurality of distinct blocks 3 spread beneath the surface S, parallel to it, and the amount of susceptor material in the blocks 3 is variable.
  • the blocks 3 comprising a different amount of susceptor material in fact, have a different capability of absorbing microwave radiations and of converting it into thermal energy. More in detail the capability of the blocks 3 of converting the heat received from the microwave radiations in thermal energy, thus determining a temperature increase, is proportional to the amount of susceptor contained in each of the blocks 3 according to the relation:
  • Q is the heat flow associated with the microwave radiations
  • m is the mass of susceptor material
  • c is the specific heat of the susceptor material
  • ⁇ T is the temperature variation of the material.
  • the heat flow due to the microwave radiations is variable in the cooking chamber of the oven, in order to obtain a similar increase in the temperature of the whole support surface of the tray, the amount of susceptor beneath the support surface is varied.
  • the blocks comprising a lower amount of susceptor i.e. a lower mass, determine a higher increase in the temperature with respect to the same heat flow.
  • the matrix of blocks 3 comprising variable amounts of susceptor material housed in the body 2 allows the baking tray 1 according to the invention to compensate the uneven distribution of the microwave radiations within the cooking chamber of the microwave oven.
  • the matrix of blocks 3 is designed so as to comprise blocks 3 having a lower amount of susceptor material in those zones of the tray 1 susceptible of being positioned in zones of the cooking chamber of the oven wherein the microwave radiations have a lower energy. This allows an optimal and homogeneous heating of the tray 1 and consequently an optimal and homogeneous heating and cooking of the food product placed on the tray 1.
  • the size of the particles of susceptor material in the composite material of the blocks 3 is in the range from 5 to 150 micron. It has in fact been verified that particles having smaller size has a tendency to agglomerate thus decreasing the efficiency of the susceptor material.
  • the susceptor material exhibits in fact better absorption properties when in the powder form, compared with the same amount of susceptor material in bulk form. For the same reason above, particles of susceptor material bigger than 150 micron do not ensure the same efficiency of the susceptor material.
  • the blocks 3 comprise variable amounts of composite material. More clearly, the amount of susceptor in the blocks 3 is varied by varying the total amount of composite material present in each of the blocks 3, that is the volume of the blocks 3. This allows to obtain different blocks 3 having different amounts of susceptor material starting from the same composition of the composite material.
  • the composite material of the blocks 3 comprises variable concentration of susceptor material. More clearly, the blocks 3 have substantially the same volume and are made of different composite materials containing a variable amount of susceptor material. This allows for instance to provide the tray 1 with blocks 3 having the same size and shape, thus reducing the manufacturing costs, still varying the amount of susceptor contained in them.
  • the body 2 comprises an internal continuous cavity 4 housing the distinct blocks 3 of composite material.
  • the blocks 3 are housed in succession along the cavity 4, preferably one contiguous to the other with no gaps between consecutive blocks 3.
  • the continuous cavity 4 has a serpentine form which extends substantially parallel to the whole support surface S, allowing to place blocks 3 of composite material susceptible of transferring thermal energy to the body 2 substantially along the whole extension of the support surface S aimed to receive the food product to be cooked.
  • the body 2 comprises a plurality of internal recesses 5 spaced apart from each other beneath the surface S, each of which houses a block 3 of composite material. This allows to place the blocks 3 in more precise positions beneath the support surface S with respect to the first embodiment, since each of the blocks 3 is housed in a specific correspondent recess 5.
  • each of the recesses 5 has a cylindrical shape, as illustrated in Figure 5.
  • the axis of each of the cylindrical recesses 5 is perpendicular to the support surface S. It has in fact been verified that the cylindrical shape of the recesses 5, and hence of the composite material blocks 3, allows to increase the transmitted microwave power, which is susceptible of reaching the food for heating and cooking it, to the detriment of the undesired reflected microwave power. This allows to reduce the pre-heating time of the tray 1 and the energy consumption required to pre-heat it.
  • the cylindrical shape of the recesses 5 favours an isotropic interaction of the microwave radiations with the composite material in directions parallel to the support surface S, hence favouring a substantially homogeneous heating of the support surface S of the tray 1.
  • the body 2 of the tray 1 comprising recesses 5 having a cylindrical shape is easy and economical to be produced.
  • each of the recesses 5 has a concave shape, in particular semispherical, as illustrated in Figure 6. This shape of the recesses 5, and hence of the blocks 3, allows to maximize the transmitted microwave power, thus further reducing the pre-heating time and energy consumption.
  • the recesses 5 have all identical shape and dimensions. This allows to simplify the production process of the tray 1 and hence to reduce the manufacturing costs.
  • the blocks 3 to be positioned in the recesses 5 may have all the same shape and dimensions, in case the concentration of the susceptor in the composite material of the different blocks 3 is modified. Differently, in case the different amount of susceptor in the blocks 3 is reached by modifying the total amount of composite material, the blocks 3 may have different dimensions and might be obtained by partially filling the recesses 5.
  • the maximum diameter of the cylindrical or concave recesses 5 is comprised within the range from 50 mm to 75 mm. In a further embodiment the depth of the recesses is comprised within the range from 5 mm to 10 mm.
  • the body 2 of the tray 1 comprises recesses 5 having different shape and/or dimensions, as for instance illustrated in Figure 4.
  • This embodiment is preferred in case the different amount of susceptor material in the blocks 3 is reached by modifying the volume of the blocks 3, i.e. the amount of composite material.
  • the different recesses 5 might have different maximum diameter, as in Figure 4, or might have different depth.
  • the body 2 comprises a first portion 6 having the support surface S and a first coupling surface 7, substantially parallel to the support surface S, and a second portion 8 having a second coupling surface 9 substantially parallel to the first coupling surface 7 of the first portion 6.
  • the first coupling surface 7 and the second coupling surface 9 are fixed to each other.
  • the first coupling surface 7 and the second coupling surface 9 are fixed to each other by means of a refractory binder and, preferably, by means of a cementitious binder. This ensures a structural continuity and a substantially homogeneous thermal behaviour of the body 2 of the tray 1.
  • the first coupling surface 7 and the second coupling surface 9 comprise respective coupling frames 10, one of which embossed and the other debossed, designed to match to each other.
  • the second portion 8 further comprises a base surface B substantially parallel to the second coupling surface 9 and opposite to the support surface S when the first portion 6 and the second portion 8 are coupled.
  • the body 2 comprises two portions 6 and 8 allows to simplify the manufacturing process, since the internal cavity 4 or the internal distinct recesses 5 can be easily obtained on one of the coupling surfaces 8 or 10 before fixing the first portion 6 and the second portion 8 to each other.
  • the internal continuous cavity 4, according to the first embodiment of Figure 1, or the internal distinct recesses 5, according to the second embodiment of Figures 2-6 are obtained on the first coupling surface 7 of the first portion 6.
