DETAILED DESCRIPTION

[0030] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0031] Referring now to the FIGS., a grill 20 is illustrated including one or more grill stations 21. In the illustrated embodiment, the grill includes four grill stations 21 including a first grill station 21a, a second grill station 21b, a third grill station 21c, and a fourth grill station 2 Id. It is understood that embodiments disclosed herein are not limited to four grill stations 21 and the grill 20 may include any number of grill stations 21. Each grill station 21 includes a lower platen assembly 24 and an upper platen assembly 26 operably connected to a rigid base structure 22. The rigid base structure 22 may be composed of an upper mounting structure 22a supporting the upper platen assembly 26 and a lower mounting structure 22b supporting the lower platen assembly 24. The lower platen assembly 24 includes a lower grilling plate 32 and the upper platen assembly 26 includes an upper grilling plate 34. [0032] At least one of the upper platen assembly 26 and the lower platen assembly 24 may move from a cooking position seen by the first grill station 21a to a non-cooking position seen by the second grill station 21b, third grill station 21c, and fourth grill station 2 Id. The cooking position is a position where the upper platen assembly 26 and the lower platen assembly 24 may transfer heat through grilling plates 34, 32 to food products 10. At least one of the upper grilling plate 34 and the lower grilling plate 32 may be in physical contact with the food product 10 when in the cooking position. Heat may be transferred to from the grilling plates 32, 34 to the food products 10 when the upper grilling plate 34 is physically touching the food products 10 and the lower grilling plate 32 is touching the conveyor belt 70. In some embodiments, the cooking position may include multiple positions where the heat may be transferred from the grilling plates 32, 34 to the food product 10 in order to cook the food product 10. For example, at a distance Dl the grilling plates 32, 34 may just be touching the food product 10/conveyor belt 70 in a cooking position; however if the distance Dl is decreased the grilling plates 32, 34 may apply increased pressure to the food product 10 while remaining in a cooking position. Further, the cooking position may also be a position where the upper grilling plate 34 and/or the lower grilling plate 32 are not physical contact with the food product 10 but rather the heat is being transferred from the grilling plates 32, 34 to the food product 10 through a non-contact means, such as, for example an infrared heater. In a non-limiting embodiment, at least one of the upper grilling plate 34 and the lower grilling plate 32 may be a non-contact heater.

[0033] In a non-liming embodiment, both the upper platen assembly 26 and the lower platen assembly 24 move from the cooking position (e.g. as shown by the first grill station 21a) to the non-cooking position (e.g. as shown by the second grill station 21b), as seen in FIG. 2. In another non-limiting embodiment, either one of the upper platen assembly 26 or the lower platen assembly 24 may be fixed while the other moves. In yet another non-limiting embodiment, the upper platen assembly 26 may be fixed and the lower platen assembly 24 may move from the cooking position (e.g. as shown by the first grill station 21a) to the non-cooking position (e.g. as shown by the second grill station 21b). Alternatively, in another non-limiting embodiment, the lower platen assembly 24 may be fixed and the upper platen assembly 26 may move from the cooking position (e.g. as shown by the first grill station 21a) to the non-cooking position (e.g. as shown by the second grill station 21b), as seen in FIG. 1.

[0034] The upper platen assembly 26 may be movably attached to the upper mounting structure 22a with one or more actuators 50 such that the upper platen assembly 26 is configured to move between the cooking position (e.g. as shown by the first grill station 21a) to the non-cooking position (e.g. as shown by the second grill station 21b). The upper platen assembly 26 may be vertically lowered and raised in a generally linear motion. Alternatively, the upper platen assembly 26 may be operably connected to the upper structure 22a by a hinged connection (not shown) such that the upper platen assembly 26 is configured to pivot relative to the conveyor belt 70. The actuators 50 may be the hinged connected.

[0035] The lower platen assembly 24 may be movably attached to the lower mounting structure 22b with one or more actuators 50 such that the upper platen assembly 26 is configured to move between the cooking position (e.g. as shown by the first grill station 21a) to the non-cooking position (e.g. as shown by the second grill station 21b), as seen in FIG. 2. The lower platen assembly 24 may be vertically lowered and raised in a generally linear motion. Alternatively, the lower platen assembly 24 may be operably connected to the lower structure 22b by a hinged connection (not shown) such that the lower platen assembly 24 is configured to pivot relative to the conveyor belt 70. The actuators 50 may be the hinged connected.

[0036] Alternatively, instead of moving the lower platen assembly 24 up so that the lower grilling plate 32 touches the conveyor belt as seen in FIG. 2, the upper platen assembly 26 may apply pressure to the food product 10 to move the conveyor belt 70 downward so that the conveyor belt 70 touches the lower grilling plate 32 as seen in FIG. 1. The conveyor belt 70 may be movably attached to the rigid base structure 22. The conveyor belt 70 may be movably attached to the rigid base structure 22 through one or more basing mechanisms 70. In the embodiment of FIG. 1, a biasing mechanism 74 is operably connected to each roller 72 of the conveyor belt 70 such that the conveyor belt 70 is allowed to move downward and touch the lower grilling plate 32 when pressure is applied to the conveyor belt 70 by the upper platen assembly 26. Advantageously, the biasing mechanisms 70 allows the food product 10 to be thermally disconnected from the lower grilling plate 32 when not in the cooking position as seen by the second grilling position 21b, the third grilling position 21c, and the fourth grilling position 21d in FIG. 1. The biasing mechanism 70 may be a spring in one non-limiting example. In FIG. 1, the lower grilling platen assembly 24 is rigidly connected to the lower structure 22b and the rollers 72 may be movably attached to the lower structure 22b. Whereas, in FIG. 2, the lower grilling plates 32 are movably attached to the lower structure 22b through the actuators 50 and the rollers are rigidly connected to the lower structure 22b (rigid connection not shown).

[0037] A food product dispenser 55 may be configured to place each food product 10 on the conveyer belt 70. The food product dispensers 55 may also be configured to form the food product 10 into patties in a non-limiting example. The conveyer belt 70 of each grilling station 21 is configured to move the food products 10 between the lower grilling plate 32 and the upper grilling plate 34 when the at least one of the upper platen assembly 26 and the lower platen assembly 24 is in the non- cooking position. It is understood that the grilling plates 34, 32 may vary in size and thus the number of food products 10 cooked by each grilling station may also change. At least one of the upper platen assembly 26 and the lower platen assembly 24 is moved from the non-cooking position to the cooking position when the food product 10 is in between the lower grilling plate 32 and the upper grilling plate 34. When in the cooking position, the food product 10 is exposed to a grilling surface 35 of the upper grilling plate 32. A heating surface 33 of the lower grilling plate 32 transfers heat to the food product 10 through the conveyor belt 70. The conveyor belt 70 melt be composed of a thermally conductive material such as, for example, steal, relief sheet metal, Teflon, thin stainless steel, or similar conductive and flexible material.

[0038] The grilling surface 35 of the upper grilling plate 34 and the heating surface 33 of the lower grilling plate 32 may be separated by a distance Dl . Heat is applied to the food product 10 for a selected period of time in order to cook each of the food products 10 to a selected degree of doneness (i.e. rare, medium-rare, medium, medium-well, well-done). The distance Dl may be adjusted automatically or manually during the selected period of time while cooking the food products 10 and also when cooking of the food products 10 is completed. The distance Dl may be adjusted automatically by the actuators 50 through a controller 60 or manually by an operator via the handles 30a, 30b. Advantageously, by adjusting the distance Dl, the pressure applied to the food product 10 may be adjusted to control desired cooking techniques. For example, increased pressure (i.e. decreased distance Dl) or active compression may be utilized to apply a sear to each of the food product 10 at the beginning of the selected period of time, then the pressure may be decreased (i.e. increased distance Dl) for normal cooking during a remaining portion of the selected period of time. Advantageously, active compression may be used to apply pressure at various intervals at any time during the cooking cycle. The frequency, compression amount, and duration may all be programmable through the controller 60 and dependent on the desired product characteristic outputs required (e.g. degree of doneness). The degree of doneness may be, such as, for example, rare, medium-rare, medium, medium-well, and well-done. It is important to note that the degree of doneness may be judged by specific temperatures (e.g. 140°F, 160°F, 180°F... etc.) assigned to the subjective terms of rare, medium-rare, medium, medium -well, and well-done.

[0039] The lower grilling plate 32 is configured to provide heat to the lower side 10b of each of the food product 10 located on the conveyer belt 70 and the upper grilling plate 34 is configured to provide heat to an upper side 10a of each of the food product 10 located on the conveyor belt 70. The upper and lower grilling plates 32, 34 are heated by a heater (not shown) to cook the food product 10. In order to transmit heat to the food items cooked by the grill, the lower and upper grilling plates 32, 34, respectively, may be formed of a heat-conducting material, such as cast aluminum, abrasion-resistant steel, cast iron, stainless steel, mild steel, a ceramic material, or other suitable heat conducting materials used in grills. Although the lower and upper grilling plates 32, 34 are shown as having a rectangular shape, one or both of the grilling plates 32, 34 may also be formed into other shapes, such as circular or oval shapes for example. [0040] The actuators 50 may also be used to control the tilt, angle, and/or attitude of the grilling plates 32, 34. Although one actuator 50 is illustrated for each grilling plate 32, 34 the FIGS., embodiments having any number of actuators 50 are within the scope of the invention. For example, one or more actuators 50 may be used. FIGs. 1 and 2 show that the actuators 50 connect the upper platen assembly 26 to the upper mounting structure 22a and FIG. 2 shows that the actuators 50 connect the lower platen assembly 24 to the lower mounting structure 22b; however a person of ordinary skill in the art may understand that various of types of actuator connections would allow relative movement of grilling plates 32, 34 and the disclosure is not limited to the actuator connection shown in FIGs. 1 and 2. For instance, the actuators 50 may connect the upper platen assembly 26 to the upper grilling plate 34 and the lower platen assembly 24 to the lower grilling plate 32. [0041] The grill 20 include a controller 60 configured to control the operation of the grill 20. The controller 60 may be in electronic communication with the actuators 50, the upper platen assembly 26, the lower platen assembly 24, the upper grilling plate 34, the lower grilling plate 32, the conveyor belt 70, and the food product dispenser 55. The controller 60 may include a processor and memory. For ease of illustration, the processor and memory are not shown in FIGs. 1 and 2. The processor can be any type or combination of computer processors, such as a microprocessor, microcontroller, digital signal processor, application specific integrated circuit, programmable logic device, and/or field programmable gate array. The memory can be a non-transitory computer readable storage medium tangibly embodied in or operably connected to the path determination system including executable instructions stored therein, for instance, as firmware. The controller 60 is configured to operate the actuators 50, the upper platen assembly 26, the lower platen assembly 24, the upper grilling plate 34, the lower grilling plate 32, the conveyor belt 70, and the food product dispenser 55. [0042] Each actuator 50 may be operated independently by the controller 60.

Utilizing multiple actuators 50 on each grilling plate 32, 34 may allow the grilling plates 32, 34 to be arranged in a non-horizontal configuration. Advantageously, arranging the plates in a non-horizontal configuration would allow for enhanced control of grease migration (flow of cooked grease from cooking food products 10). In one embodiment, the actuators 50 are linear actuators, such as hydraulic, pneumatic, or mechanical actuators for example. One or more sensors (not shown) are configured to monitor each of the plurality of actuators 50 and detect the distance Dl between lower grilling plate 32 and the upper grilling plate 34. In one embodiment, the sensors are Hall Effect sensors or encoders configured to monitor the position of a movable portion 54 of the actuators 50. Alternatively, other types of sensors, such as sensors configured to monitor current, load, resistance, or another characteristic of the plurality of actuators 50 for example, is also within the scope of the disclosure. In another embodiment, the motor resistance of each actuator 50 may be used to monitor the position of each actuator 50. For example, the increased motor resistance the increased the compression of the grilling plates 32, 34 and once a maximum resistance is reached, a maximum compression is reached and thus the grilling plates may be in direct contact at the maximum resistance of the motor of each actuator 50. This may be used during the calibration of the upper platen assembly 26 to ensure it is parallel to the lower platen assembly 24. Through the distance Dl may be adjusted to accommodate the variation of thickness of the food products 10 to be cooked on the grill 20. Further, each actuator 50 may apply a positive pressure on the grilling plates 32, 34 and consequently on the food products 10 as they are being cooked on the grill 20, resulting in compression of the food products 10.

[0043] The grill 20 may be automatically calibrated to ensure that the distance Dl between the lower grilling plate 32 and the upper grilling plate 34 is maintained at a desired size. By calibrated, it is meant that the upper grilling plate 34 and the lower grilling plate 32 are level to one another to ensure proper cooking of food items. In one example, the grill 20 is calibrated daily to correct any unleveling of the lower grilling plate 32 that may have occurred during the previous day. The calibration of the grill may be done automatically by the grill 20 utilizing the actuators 50 without the need for external tools, gages, or operators.

[0044] The grill 20 may have a single conveyor belt 70 for all the grill stations 21 (not shown) or a conveyor belt 70 for each grill stations, as seen in FIGs. 1 and 2. A conveyor belt 70 for each grill station 21 may move the food product 10 between the grill stations 21. For instance, the conveyor belt 70 of the first grill station 21a may be considered an indexing conveyor belt as it sets the pace for the conveyor belts 70 of the other grill stations 21b, 21c, 2 Id. Once the food product 10 is placed on the conveyor belt 70 of the first grill station 21a, the conveyor belt 70 of the first grill station 21a may move the food product 10 in between the grilling plates 34, 32 of the first grill station 21. The conveyor belt 70 of the first grill station 21a may pass the food product 10 to a conveyor belt 70 of a later grill station 21b, 21c, 2 Id. Each grill station 21 is configured to cook the food product 10 a selected degree of doneness.

[0045] As seen in FIGs. 1 and 2 each grill station 21 may be enclosed within an oven 80. In an alternate embodiment, a single grill 21 may be located outside of the oven 80 to cook the food product to the final degree of doneness. The oven 80 is configured to maintain a holding temperature such that the food product 10 is kept warm but not being cooked unless a grilling plates 32, 34 are in the cooking position. The holding temperature may be greater than a temperature to prevent bacteria growth in the product 10 but less than a temperature required to cook the food product 10. The holding temperature may be 155°F in one non-limiting example. In one example, the food product 10 may be partially cooked to a first selected degree of doneness by a grill station 21 when the food product 10 first enters the oven 80. The partially cooked food product 10 may be kept warm in the oven 80 until it is time to fully cook the food product 10 (e.g. an order has been placed for the burger). Then a grill station 21 may cook the food product 10 to a second degree of doneness and the conveyor belt(s) 70 will moved the food product out of the oven. It is understood that the food product 10 may be cooked to the first degree of doneness and then to the second degree of doneness by two separate grill stations 21 or the same single grill station 21. In one example, the conveyor belt 70 of the first grill station 21a may move the food product 10 into the oven and the first grill station 21a may cook the food product 10 to the first degree of doneness, then the food product 10 may be held in the oven for a period of time and the first grill station 21a may cook the food product 10 to the second degree of doneness. In a second example, the conveyor belt 70 of the first grill station 21a may move the food product 10 into the oven and the first grill station 21a may cook the food product 10 to the first degree of doneness, then the food product 10 may be held in the oven for a period of time, moved to the second grill station 21b, and the second grill station 21b may cook the food product 10 to the second degree of doneness. It is understood, that the food product 10 may stop at any grill station 21 to be cooked to any degree of doneness desired. The controller 60 may be configured to control coordination between each grill station 21 to cook each food product 10.

[0046] Additionally the grill 20 includes an exhaust hood 82 in fluid connection to the oven 80. The exhaust hood 82 is configured to remove exhaust from the oven 80 and each of the grill stations 21 within the oven 80. The exhaust is a byproduct from the cooking process of the food product 10. Additionally, the grill 20 may include a grease trap 90 configured to capture grease and food particles remaining from the cooking process of the food products 10. The grease trap 90 may be fluidly connected to a grease container 92 configured to store the grease and food particles from the grease trap 90.

[0047] Referring now to FIG. 3, with continued reference to FIGs. 1 and 2. FIG. 3 shows a flow chart of method 300 of cooking food products 10, in accordance with an embodiment of the present disclosure.

[0048] At block 302, one or more conveyor belt 70 transports a food product 10 in between an upper grilling plate 34 of a first grill station 21a and a lower grilling plate 32 of the first grill station 21. The conveyor belt 70 is located in between the upper grilling plate 34 and the lower grilling plate 32, as seen in FIGs. 1 and 2.

[0049] At block 304, one or more actuators 50 move at least one of the upper grilling plate 34 and the lower grilling plate 32 from a non-cooking position to a cooking position when the food product 10 is between the upper grilling plate 34 and the lower grilling plate 32. As mentioned above, the one or more actuators 50 are operably connected to at least one of the upper platen assembly 26 and the lower platen assembly 24. The upper platen assembly 26 including the upper grilling plate 34 and the lower platen assembly 24 including a lower grilling plate 32. Alternatively, the one or more actuators 50 may be operably connected directly to at least one of the upper grilling plate 34 and the lower grilling plate 32. The upper grilling plate 34 and the lower grilling plate 32 are separated by a distance Dl .

[0050] At block 306, the upper grilling plate 34 cooks the food product 10 when at least one of the upper grilling plate 34 and the lower grilling plate 32 is in the cooking position. At block 308, the lower grilling plate 32 cooks the food product when at least one of the upper grilling plate 34 and the lower grilling plate 32 is in the cooking position. The one or more actuators 50 may adjust the distance Dl during cooking. Advantageously, adjusting the distance Dl adjusts the pressure placed on each of the selected food products 10 by the grilling plates 32, 34. [0051] At block 310, one or more actuators 50 moves at least one of the upper grilling plate 34 and the lower grilling plate 32 from the cooking position to the non-cooking position after the food product 10 is cooked to a first degree of doneness. The first degree of doneness may be enough to cook the food product 10 about 75% in a non-limiting example and then a second degree of doneness may finish cooking the food product 10 the remaining 25% to the final degree of doneness. Each degree of doneness may vary depending upon the final degree of doneness desired, such as, for example, rare, medium-rare, medium, medium-well, and well-done. It is important to note that the degree of doneness may be judged by specific temperatures (e.g. 140°F, 160°F, 180°F... etc.) assigned to the subjective terms of rare, medium-rare, medium, medium-well, and well-done.

[0052] At block 312, the food product 10 is allowed to remain within the oven 80 for a period of time. The oven 80 is configured to maintain a holding temperature within the oven 80. The holding temperature may be greater than a temperature to prevent bacteria growth in the product 10 but less than a temperature required to cook the food product 10. During the period of time the food product 10 may be shifted to different grill stations 21 to accommodate or make room for new food product 10 entering the oven 80. The period of time may end when an order is placed for the food product 10, such as, for example by a customer at a register or drive through window. When the period of time is over, the first grill station 21a may finish cooking the food product 10 to the second degree of doneness. Alternatively, the first grill station 21a may transfer the food product 10 to another grill station 21, such as, for example, the second grill station 21b to finish cooking the food product 10 to the second degree of doneness when the period of time is over. The second grill station 21b will finish cooking the food product 10 to the second degree of doneness. The food product 10 may be transferred from one grill station 21 to another via one or more conveyor belts 70. The second degree of doneness may be equal to the final degree of doneness but it is understood that the food product 10 may be moved to one or more additional grill stations 21 to further cook the food product 10 to additional degree of doneness until the final degree of doneness is reached. When the food product 10 has finished cooking to the final degree of doneness, then the food product 10 may be moved out of the oven 80. In an alternative embodiment, the food product 10 may be cooked to final degree of doneness by a grill station 21 located outside of the oven 80 (not shown).
