Marketing Information Project description Induction oven is an electrical oven based on Minerva 67 l Premium platform provided with an additional plug & play tray with induction coil (dedicated designed & rectangular shaped). The heater is powered by means of an electric plug (male part into the tray, female part into the oven back wall). The electronic control of the oven is integrated with the one for the induction portion, in such a way the user can operate the induction module through the Oven User Interface.(Ui) The Oven keeps all the functionalities of a traditional oven, with the plus of the induction contribution, if needed. Due to the specific design of the plug, is not possible to have pyrolitic cleaning with this oven.
Marketing Information Benefits Consumers are looking for latest technologies to improve their life Willing to save cooking time and energy, without compromise on Cooking results Propose the Best Oven worldwide: save more than 30% NRJ, faster up to 25%, while offering excellent cooking performances Break- trough technology combining induction & traditional heating elements Significantly Improve speed to cook and energy saving; Keep the same functionality of a traditional oven; No tradeoff in cooking performance;

Technical Information Components / accessory Cooking vessel specs According to experimental verifications, cooking vessel for induction oven should comprise a bottom made of a stack of different materials characterized by: Outer layer: metal base is made up of an alloy which is ferromagnetic in the working temperature range of the vessel/induction module. Thickness e E Core or Heat Distribution Layer: Its main function is diffuse heat uniformously in the vessel; material with high thermal conductivity preferably (e.g. Aluminium, Aluminium alloy, Copper). Thickness e C Inner layer: the vessels body, mechanically stable so that the vessel retains its geometry, in particular the flatness of the base in contact with the top of the inductor; possibly being covered with non-stick or anticorrosion coating. Thickness e I The presence in the vessel of a Heat Distribution Layer (6 < e C /e E > 8 ) is the way to achieve energy efficiency & time saving, without compromising cooking performances side wall Vessel bottom core Vessel bottom outer layer Vessel bottom inner layer

Basic Information Coil design / Heating distribution Entry level bake wares Cooking perfomances are not comparable to Minerva quality standards in terms of browning evenness of the food product. To be noted as the unevenness affected both bottom and top of the food preparation Induction Oven Entry level roast pan NOTES Bottom browning distribution corresponds to heat distribution observed during thermal image analysis run on 21 and 22 Turns coils (see pictures for comparison) Both coil design when using a vessel not equipped with a HDL gave cooking results not comparable with Minerva Oven Coil shows hot spots, evidently visible on bottom and recognizable even on top Induction Oven Entry level roast pan Coil heat distribution is more even and spread on a larger surface. Trials made to minimize bottom browning dish homogenity went in the direction of reducing induction contribution to cooking process (100W power). Thus drove to a reduction of advantages achieved. (energy efficiency, time saving)
Basic Information Cooking result Induction Oven: Lasagna: cooking result using different coil power Bottom burned due too high induction power ; Difficult to remove food from pot Good browning level
