Food cooking oven, comprising a thermometric probe adapted to be introduced in the food to be cooked and to generate a signal that is representative of the detected temperature, in which said signal is sent to appropriate processing and display means capable of working out a final information (F) depending in a combined manner on both the detected temperatures and the cooking time. The oven is further provided with selection means adapted to send selective commands to said processing means.These processing means are furthermore adapted to automatically perform a comparison of said final information with said selective commands and issue respective signals, corresponding to the outcome of said comparison, towards appropriate indicator means. These signals are indicative of the period of time during which the food can be kept stored, ie. preserved after cooking, since they represent the bacterial count at the end of the cooking process.

1. A method of running a food cooking oven, intended in particular for use in foodservice and catering applications, comprising the introduction of a probe in the interior of the food being cooked and generating an electric signal that is representative of the detected temperature, in which said signal is sent to an appropriate processing and control device, characterized in that said processing and control device is adapted to work out an information (F) that depends in a combined manner on both the temperatures detected by said probe and the cooking time, and that said information is a value that is representative of the reduction in the bacterial content of the cooked food, and that said processing and control device selects, for the real-time calculation of said information (F), the lowest temperature being detected by a plurality of temperature sensors located at different points ( 20 , 21 , . . . 25 ) of said probe that is preferably a pin probe ( 11 ). 2. A method for running a food cooking oven according to claim 1, characterized in that it is further provided with selector means ( 5 , 6 ) that are adapted to classify the food being cooked according to predefined categories (A, B) and to send a multiplicity of pre-defined values (F o , F 1 , F 2 . . . F n ), depending on the selected category, towards said processing and control device, which is in turn adapted to perform a comparison of such worked-out value of F with said values (F o , F 1 , F 2 . . . F n ) and to issue respective signals (UNSAFE, SAFE- 0 , SAFE- 1 , . . . ), corresponding, to the outcome of said comparison, towards appropriate indicator or display means ( 7 ). 3. A method for running a food cooking oven according to claim 2, characterized in that, if said comparison identifies a value of said information being lower than a pre-determined limit (F o ), a specific warning signal (UNSAFE) is automatically generated and issued for display ( 7 ). 4. A method for running a food cooking oven according to claim 3, characterized in that, if at the end of the cooking process said comparison gives a result of said value (F) being lower than a pre-determined limit (F o ), the cooking process itself is automatically caused to go further on until the outcome of said comparison eventually attains at least said pre-defined value (F o ), in which case the visual message on the display is updated accordingly (UNSAFE>SAFE 0 ). 5. A method for running a food cooking oven according to claim 2 or 3 or 4 , characterized in that said respective signals (UNSAFE, SAFE- 0 , SAFE- 1 , SAFE- 2 . . . ) are representative of the length of time during which said cooked food may then be kept in store before being served after cooking. 6. A method for running a food cooking oven according to any of the preceding claims, characterized in that said processing, ie. calculation is performed through the integration of the function that is representative of a temperature of the food being cooked. 7. A method for running a food cooking oven according to claim 1, characterized in that said probe is a pin-like core temperature probe ( 11 ) provided with a plurality of temperature sensors located at different points ( 20 , 21 , . . . 25 ), and that said processing and control device selects, for the real-time calculation of said information (F), the lowest temperature being detected by said plurality of temperature sensors.
