Hygienic oven cooking systems and methods
View Patent ↗Disclosed are methods and system for reducing or eliminating the possibility of cross-contamination between food to be cooked in a cooking device and food cooking in the cooking device. The methods and systems determine the placement into a cooking device of food product to be cooked by the distance sensor, determine a hygienic safe cooking time (HSCT) for that product based on the identification of food product to be cooked, and compare the HSCT to one or more remaining cooking times of food product cooking in the cooking device on levels below and/or above the desired placement of the food product to be cooked. Various methods of identifying the food to be cooked may be employed, both manual and automatic. As a result of the comparison, the methods and systems of the disclosure can identify safe carrier/tray level(s) for accepting placement of the food to be cooked.
1. A system for reducing or eliminating cross-contamination between food to be cooked in a cooking device and food cooking in the cooking device, the system comprising:
a controller having a memory, wherein the memory stores a hygienic safe control time (HSCT) for the food to be cooked, and wherein the memory stores cooking times, remaining cooking times and carrier/tray levels for each food cooking in the cooking device;
and
a user interface including a display and user input device, wherein the system:
receives an identification of the food to be cooked via the user input device of the interface;
obtains a hygienic safe control time (HSCT) for the food to be cooked from the memory;
obtains a remaining cooking time and a carrier/tray level for each food cooking in the cooking device from the memory;
compares the HSCT to each remaining cooking time, wherein the controller performs the comparison; and
identifies safe carrier/tray level(s) for accepting placement of the food to be cooked, wherein the controller performs the identification.
2. The system according to claim 1 , wherein the system provides the identification of safe carrier/tray level(s) for accepting placement of the food to be cooked on the display of the user interface.
3. The system according to claim 1 , wherein the system further provides an alert to a user if food to be cooked into the cooking device is attempted to be loaded at an unsafe carrier/tray level.
4. The system according to claim 1 , wherein the system further comprises a locking mechanism configured to lock one or more unsafe carrier/tray levels so that food to be cooked cannot be placed on the one or more locked unsafe carrier/tray levels.
5. The system according to claim 1 , wherein the system displays identified safe carrier/tray level(s) on the user interface.
6. The system according to claim 1 , wherein the system locks unsafe carrier/tray level(s).
7. The system according to claim 1 , wherein the system provides a warning that an unsafe carrier/tray level is attempted to be used.
8. The system according to claim 1 , wherein system identifies the carrier/tray level in the cooking device at which food to be cooked is going to be placed.
9. The system according to claim 2 , wherein the system identifies the carrier/tray level by capturing an image of a carrier/tray level indicator or by an auto-focus mechanism.
10. The system according to claim 4 , wherein the HSCT is fixed for all food to be cooked in the cooking device.
11. The system according to claim 4 , wherein the HSCT is different for each food to be cooked in the cooking device.
12. The subsystem according to claim 5 , further comprising causing the processor to perform the action of displaying the safe carriers/trays levels on the user interface.
13. The subsystem according to claim 6 , further comprising causing the processor to perform the action of locking unsafe carrier/tray level(s).
14. The subsystem according to claim 7 , further comprising causing the processor to perform the action of providing a warning that an unsafe carrier/tray level is attempted to be used.
