This device does not heat food directly with a laser, and it uses a laser oscillator to heat the bottom of a cooker.
    [0011] Patent Application No. JP 2002147762A2, by Asano Hi-deki, for a food cooking apparatus, published May 22, 2002, describes a microwave oven having a semiconductor laser irradiation unit that radiates a laser beam that has a specific wavelength (0.8 μm and 1.5 μm) on food products accommodated in a cooking chamber.
    [0012] US patent application 20080282901, Boris Much-nik, published November 20, 2008, describes a laser cooking appliance device. Muchnik shows an apparatus and method for cooking food directly with a CO2 laser, which is known to achieve a higher temperature compared to other types of laser. The laser beam is directed at a beam splitter, which splits the laser beam in half; and then mirrors are used to focus the beam to either side of the food. The split beam reaches a higher temperature than most types of lasers, so most food will be cooked in less than a second.

    [0040] It should be understood that the present invention is not limited to the illustrated user interfaces or the order of user interfaces described herein. Various types and styles of user interfaces can be used in accordance with the present invention without limitation.
    [0041] The invention will hereinafter be described in connection with a 3D printer P that uses the additive manufacturing method to print a food product using a plurality of ingredients in a process defined by a set of directions, in which each of the ingredients is contained in a respective capsule and has a plurality of ingredient parameters and rheological properties associated therewith. "Ingredient" is used hereinafter in describing the operation of a 3D printer in the production of a food product according to a recipe, by means of an additive manufacturing method. The 3D printer P has a plurality of capsule holders, each of which is configured to have removable capsules that contain ingredients inserted therein and includes a heating device for adjusting the temperature of the ingredient contained in the capsule inserted into the capsule holder. , based on ingredient parameters and properties associated with the ingredient and directions. Such a food 3D printer is described in the aforementioned International Patent Application PCT/US2014/039170. However, as will be understood by those skilled in the art, the invention can also be used in connection with any oven, i.e. any device with a closed structure which is used as a heating chamber for heating and cooking food.
    [0042] Ingredient parameters include, but are not limited to, print temperature, heating curve, extrusion speed, extrusion multiplier, time between layer deposition, axis speed, optimum nozzle diameter, vertical accuracy , horizontal accuracy, viscosity curve, density, freezing temperature, melting temperature, etc., and define how the 3D P printer handles the ingredient associated with the ingredient parameters. The rheological properties of ingredients can be readily determined by an individual of ordinary skill in the technology.
    [0043] The heating and cooking apparatus according to the present invention comprises a cooking chamber in which a food product to be cooked is situated, a laser cooking apparatus for generating at least one laser beam for heating the food product to its cooking temperature, infrared radiation heating apparatus for generating infrared radiation to heat the food product to a temperature below its cooking temperature, and a programmable data processing apparatus for controlling the laser cooking apparatus and the cooking apparatus. heating by electromagnetic radiation. It is noted that, for the purposes of this description, "heating" and "heating" and their variants (eg, "heating" and "heating") are considered synonymous, and may be used interchangeably herein.
    [0044] Referring to Figures 1 and 2, the interior of the 3DP printer, which serves as the cooking chamber 9, includes a plate 6 that has a flat surface where the food product 7 prepared by additive layer manufacturing is deposited. In one embodiment of the invention, the plate 6 is capable of absorbing infrared light, and does not reflect electromagnetic radiation, such as infrared radiation or microwave radiation. However, it will be understood by those skilled in the art that the plate 6 need not have these characteristics in order for the heating and cooking apparatus to function as intended.
    [0045] The laser cooking apparatus includes at least one laser system situated within the cooking chamber 9 of the 3D printer P, and each laser system includes at least one laser. The present invention allows a food product to be cooked using the at least one laser beam generated by the at least one laser system to heat the food product to its cooking temperature. In the accompanying drawings, the components of the laser system are designated by reference numerals 1 to 5, wherein the reference numbers associated with each laser cooking system are followed by a respective letter A or B. The at least one laser is controlled by programmable data processing apparatus computer program instructions, which manage apparatus parameters to ensure proper heating and cooking process, as described later.
    [0046] Referring to Figure 4, the programmable data processing apparatus, which is included in the 3D printer P, includes a processor 32 for executing specific computer program instructions and a controller 33 for controlling the at least one processing system. laser according to heating and cooking appliance-specific computer program instructions stored in a read-write memory (RWM). The data used by the heating and cooking appliance computer program instructions to manage the at least one laser system can also be stored on an RWM 37. The end user can enter data and instructions through a user interface 15. Preferably, the processor 32 is built-in as part of the 3D printer P, however, the 3D printer P can be configured to allow a user's external device (e.g., a computer or tablet) to communicate with the processor 32, so so that the user can control the at least one laser system of the heating and cooking appliance through his own device.
    [0047] Computer program instructions manage the specific appliance parameters and physical conditions of laser cooking systems in order to ensure a proper heating and cooking process of the food. The main apparatus parameters controlled by computer program instructions include: laser power, beam spot diameter, laser beam deflection speed, laser frequency, laser beam aiming at the precise area of the food product, temperature within the cooking chamber 9, exposure time, and rate at which the food product is withdrawn ("printed") from its capsule. Cooking the food product layer by layer can result in different textures depending on how at least one laser beam is applied to cook each layer. Computer program instructions therefore adapt apparatus parameters depending on the print design and the characteristics and components of the food product in order to determine a suitable cooking process which results in a homogeneous texture of the superimposed food layers.
    [0048] The laser type may be the same or may be different for each laser system, as well as for each laser in the stacked array of lasers in a specific laser system. In addition, the lasers in all laser systems can emit light of the same or different wavelengths; they can be applied at the same power or they can be applied at different powers; and they can be applied at the same frequency or they can be applied at different frequencies. The different frequencies are used preferentially for cooking different ingredients, for example where the ingredient in one food-containing capsule has a different main component than the ingredient in another food-containing capsule (mainly water, mainly oil, etc). Although a single laser can be used for a food product made from different ingredients, the provision of more than one laser makes the cooking process more efficient.
    [0049] Each laser system has mirror and lens systems, as is well known in the art, to deflect the laser beam and control the beam spot diameter, respectively, of its at least one laser beam. Figures 1 and 2 show mirror and lens systems comprising two optical lens systems 2 and 3 and a mirror system 4. Optical lens systems 2 and 3 transmit the laser beam 5 and cause it to converge or diverge to control the focus and spot diameter of the laser beam. The beam spot diameter must be adapted to the layer diameter of the printed food product, or the surface and volume of the unprinted food product. The beam spot diameter must also be adapted to the characteristics of the cooking process for each food product. The cooking process is determined by different device parameters, such as: the spot diameter of the laser beam (or beams), the length of time the laser beam is focused on a certain spot, the power applied to the laser, the pulse frequency of the laser, the electromagnetic wavelength of the laser, and the laser deflection pattern. In the case of spot diameter, the larger the laser beam diameter, the more scattering of the laser power and, therefore, the lower the cooking temperature applied to the food being cooked.
    [0050] The first optical lens system 2 is only required if the laser source comprises multiple emitters, and is placed just after laser 1 to converge the laser beams from the multiple emitters into a single beam. The second optical lens system 3 is placed just after the mirror system 4. The computer program instructions include instructions for controlling both optical lens systems to adjust the spot diameter to reach the required cooking temperature, which will be determined by the computer program according to which food product is being cooked, based on the thickness of the food product and the desired end result (e.g. crispy, rare, well done, etc). Optical lens systems 2 and 3 are used to adjust the beam spot diameter and focus of the laser beam 5 so that when two or more laser cooking systems are used, their beam spot diameters can be equal. or different.
    [0051] Each example mirror system 4 is placed in the beam path between the two optical lens systems 2 and 3, as shown in Figures 1 and 2 (or, in the case where there is only one lens system, between the laser 1 and optical lens system 3). The mirror system 4 is used to deflect the laser beam 5 in two dimensions in order to guide the beam spot over a precise area of the food product 7 while it is being printed, as well as after it is printed. The area to which the beam is deflected is determined by the computer program to which the food product is being cooked, based on the thickness of the food product and the end result aimed at. The mirror system 4 can deflect the laser beam 5 into the cooking chamber volume above the printing surface plate 6, as shown in Figure 2. The spot focus and the size of the laser beam 5 are controlled by the laser beam system 5. lens 3. Focus and beam spot diameter control allows for the addition of granular control to the heating and cooking speed and temperature, as a larger beam spot can increase the speed of the heating and cooking process .
    [0052] Computer program instructions include instructions for controlling each mirror system 4 to aim and direct the laser beam and to adapt the speed of beam dot movement to the print feed rate. The speed of movement of the laser beam determines the amount of time the food product is exposed to the laser beam and therefore the speed at which the laser beam cooks the food product.
    [0053] In the case where the apparatus only includes a laser system with only one laser, the laser system also includes optical elements, e.g. conventional beam splitters (not shown), to divide the laser beam emitted by the laser into two or more laser beams. Such conventional beam splitters are taught by Muchnik (Patent Application No. US 20080282901), incorporated herein by reference in their entirety.
    [0054] If the apparatus includes two or more laser systems, they can be applied together or alone and using the same or different apparatus parameters and physical conditions, during the heating and cooking process.
    [0055] At least two laser systems can be used at the same time, with the same or different device parameters and physical conditions, or they can apply only one laser system at a time. If there are two or more laser systems, which laser systems will be used at each point in time during the cooking process will be determined by the pattern and speed of the layer printing process and the food ingredient being printed on.
    [0056] The electromagnetic radiation heating device 8, shown in Figures 1 and 2, is used to heat the internal volume of the cooking chamber, in order to heat the food product to a temperature lower than its cooking temperature, for example, to bring the food product to delivery temperature or to assist in the cooking process. The electromagnetic radiation heating apparatus 8 is an emitter of electromagnetic radiation, for example an infrared heating lamp.
    [0057] The electromagnetic radiation heating device can heat the food product while it is being printed, as well as once it has been printed. Alternatively, the electromagnetic radiation heating apparatus can be used to heat any type of unprinted food. The electromagnetic radiation heating appliance can be used by itself while the laser cooking appliance is not being used or at the same time as the laser cooking appliance.
    [0058] In the case of a 3D printer, the at least one laser system can be used to cook the food product while it is being printed using additive manufacturing, or to cook the food product once it has been printed. printed by additive manufacturing. The at least one laser system can also be used in a food chamber for cooking unprinted food directly introduced into a cooking chamber.
    [0059] The method of heating and cooking a food product in accordance with the present invention will now be described with reference to the flow chart of Figures 5A and 5B. This heating and cooking method is performed based on a heating and cooking process algorithm, which is implemented by computer program instructions stored in the read-write memory (RWM) 37, and can be performed for both a printed food as unprinted 7, present in the cooking chamber 9.
    [0060] A routine to carry out the steps of the heating and cooking method is inserted, starting at block 100, each time data or a command involving heating and cooking of a food product is entered in the processor 32.
    [0061] A temperature control subroutine 105 is entered depending on whether the food product will be printed or not.
    [0062] If the food product is to be printed, control is transferred from block 105 to block 110. In block 110, recipe information is fetched from read-write memory (RWM) 37 of processor 32 built into printer P. This recipe information includes in which order the ingredients will be used in order to prepare the printed food product. From block 110, control is transferred to block 115, where ingredient-related information is also fetched from RWM 37. Ingredient-related information fetched in block 115 includes the temperature information needed to determine the heating and cooking method. . The information search step is performed for each ingredient on the P printer.
    [0063] If the food product is an unprinted food product, control is transferred from block 105 to block 120. In block 120, ingredient information is fetched from read-write memory (RWM) 37. This ingredient information include the main ingredients contained in the food product. From block 120, control is transferred to block 125, where the food product is scanned using a 3D scanner (not shown) controlled by processor 32, in order to determine the shape of the food product being heated or cooked. , which is used to determine the laser deflection pattern for the bake.
    [0064] From block 115 or block 125, control is transferred to block 130, where the laser deflection pattern will be calculated by processor 32 using information fetched from RWM 37. Information used in block 130 includes the pattern deflection that the laser cooker will follow in order to carry out cooking. From block 130, control is transferred to blocks 135 to 160, where processor 32 will use the information fetched from RWM 37 of printer P, in order to calculate power, temperature, focus diameter, pulse frequency, beam speed. laser speed and electromagnetic (EM) wavelength. The information obtained in blocks 135 to 160 will be used to recalculate the laser deflection pattern requested in block 165 to perform the cooking. This information step is performed for each food product on the P printer.
    [0065] A temperature control subroutine 170 is entered depending on whether or not the electromagnetic radiation heating apparatus 8 is required to heat the food product.
    [0066] If electromagnetic radiation heater 8 is not required, control is transferred from block 170 to block 185.
    [0067] If electromagnetic radiation heater 8 is required, control is transferred from block 170 to block 175. In block 175, processor 32 will use information fetched from RWM 37 of printer P in order to determine power required by the electromagnetic radiation heating apparatus 8 to heat the food product. Then, control is transferred from block 175 to block 180, where the processor 32 will activate the electromagnetic radiation heating apparatus 8 in order to heat the food product.
    [0068] From block 170 or block 180, control is transferred to block 185, where processor 32 will activate the laser beam in order to continue cooking. The laser beam is activated based on the configuration defined in blocks 130 to 165.
    [0069] From block 185, control is transferred to block 190, where processor 32 will provide instructions to controller 33 to move the laser beam following the laser deflection pattern recalculated in block 165 in order to cook the food product.
    [0070] A control subroutine 195 is entered depending on whether the electromagnetic radiation heating apparatus 8 is activated or not in order to heat the food product.
    [0071] If electromagnetic radiation heater 8 is not activated, control is transferred from block 195 to block 205.
    [0072] If EMF heater 8 is activated, control is transferred from block 195 to block 200, where processor 32 provides instructions to controller 33 to turn off EMF heater 8 once the food product has been heated. A table is saved in RWM 37 that includes, for each food product, the temperature at which it is cooked, the temperature at which it is heated and the device parameters to obtain the temperature. Cooking temperature is related to different appliance parameters including power, time, frequency, spot diameter, wavelength and pattern. Appliance parameters will depend on the characteristics of the cooking process for each food product. Specifically, the beam spot diameter has two main functionalities: (1) It adapts to the layer diameter for the printed food and surface/volume for the unprinted food, and (2) controlling the temperature by controlling the laser power with the diameter of the laser beam.
    [0073] From block 195 or block 200, control is transferred to block 205, where processor 32 instructs controller 33 to turn off the laser beam once the food product has been cooked.
    [0074] A control subroutine 210 is entered depending on whether the cooking process has ended or not.
    [0075] If the cooking process has not been completed, control is transferred to block 135 to recalculate the appliance parameters that control the heating and cooking process, as well as laser deflection patterns, in order to complete the cooking process. heating and cooking process suitable for the food product. OTHER IMPLEMENTATION DETAILS4. TERMS
    [0076] The detailed description contained in this document is represented partially in terms of processes and symbolic representations of operations by a conventional programmable data processing apparatus. The processes and operations performed by the programmable data processing apparatus include the manipulation of signals by a processor and the maintenance of those signals within data packets and data structures residing on one or more media within memory storage devices. Generally speaking, a "data structure" is an organizational schema applied to data or one so that specific operations can be performed on the data or data modules so that specific relationships are established between the organized parts of the data structure.
    [0077] A "data packet" is a type of data structure that has one or more related fields, which are collectively defined as a unit of information transmitted from one device or program module to another. Thus, symbolic representations of operations are means used by individuals skilled in the art of computer programming and computer construction to transfer teachings and disclosures more effectively to others skilled in the art.
    [0078] For the purposes of this discussion, a process is generally conceived to be a sequence of steps performed by a programmable data processing apparatus that leads to a desired result. These steps often require physical manipulations of physical quantities. Typically, though not necessarily, these quantities take the form of electrical, magnetic, or optical signals that have the ability to be stored, transferred, combined, or otherwise manipulated. It is conventional for those skilled in the art to refer to representations of these signals as bits, bytes, words, information, data, packets, nodes, numbers, points, inputs, objects, images, files, or the like. It should be noted, however, that these and similar terms are associated with physical quantities suitable for computer operations, and that these terms are merely conventional labels applied to physical quantities that exist within and during the operation of the programmable data processing apparatus.
    [0079] It should be understood that manipulations within the programmable data processing apparatus are often referred to by terms such as issuing, sending, altering, adding, deactivating, determining, comparing, reporting and the like that are often associated with manual operations performed by a human operator. The operations described in this document are machine operations performed in conjunction with various inputs provided by a human operator or user interacting with the programmable data processing apparatus. 5. HARDWARE
    [0080] It should be understood that various types of programmable data processing apparatus may be used with program modules constructed in accordance with the teachings described herein. It may prove advantageous to construct a specialized apparatus to carry out the method steps described herein with programs or logic connected by cable in non-volatile memory, such as read-only memory. 6. PROGRAM
