Abstract
Description
Technology Field
[0001] The present invention relates to an automatic cooking system for food trucks capable of real-time sugar content measurement. Background Technology
[0002] Generally, food trucks are mobile restaurants equipped with cooking facilities in vehicles and have recently established themselves as a new trend in the food service industry.
[0003] Food trucks are gaining popularity as a startup item for small business owners because they have the advantage of requiring less initial investment than traditional fixed-location restaurants and allowing for operation regardless of location.
[0004] Such food trucks are operated by installing cooking facilities inside a box van that has been modified from the cargo compartment of a vehicle.
[0005] The interior of the box van is equipped with basic kitchen facilities such as a countertop, sink, and refrigerator, along with various appliances necessary for cooking, while a counter for ordering and pickup is provided on the exterior.
[0006] However, conventional food trucks are operated by having cooks prepare the food directly, so the taste of the food may not be consistent depending on the cook's skill level and condition, and there was a problem in that it was difficult to accurately control quantitative taste elements, such as sweetness.
[0007] In addition, there was a problem with low work efficiency due to the nature of food trucks, where cooks had to work in a limited space.
[0008] In particular, during peak order times, it was difficult to handle the volume of orders because multiple tasks had to be performed simultaneously in a confined space, leading to long customer waiting times.

[0061] FIG. 1 is a schematic diagram showing an automatic cooking system for a food truck according to an embodiment of the present invention.
[0062] Referring to FIG. 1, an automatic cooking system (100) for a food truck capable of real-time sugar content measurement according to an embodiment of the present invention (hereinafter referred to as the 'automatic cooking system (100) for a food truck') is housed in a box van (V) of a food truck (FT) and automatically cooks food, and includes a cooking robot (1), a control unit (2), and a kiosk (3).
[0063] The cooking robot (1) is configured to cook food using cooking devices (not shown) placed inside the box van (V), and to measure and adjust the sugar content of the food being cooked in real time.
[0064] FIG. 2 is a schematic diagram showing a cooking robot according to an embodiment of the present invention.
[0065] Referring to FIG. 2, the cooking robot (1) may include a robot arm (11) and a cooking measurement module (12).
[0066] The robot arm (11) is equipped with a cooking tool for cooking food at its end and may have multiple joint structures to enable various movements.
[0067] More specifically, the robot arm (11) has four to six or more axes driven by servo motors, and each joint can rotate 360 degrees. Also, a detachable means for attaching and detaching a cooking tool can be provided at the end of the robot arm (11).
[0068] For example, the detachable means can be attached to the cooking tool through magnetic force or a fastening means. Also, various cooking tools can be placed inside the box van (V). Accordingly, the robot arm (11) can selectively replace the cooking tool according to the cooking process.
[0069] The robot arm (11) can be electrically connected to and controlled by the control unit (2).
[0070] The cooking measurement module (12) is mounted on the robot arm (11) and can measure the sugar content of the food.
[0071] More specifically, the cooking measurement module (12) can measure the sugar content of the food using a near-infrared spectral method while not in contact with the food.
[0072] The cooking measurement module (12) may include a non-contact sugar content meter (121) and an angle adjustment unit (122).
[0073] The non-contact sugar content meter (121) can measure the sugar content of food using a near-infrared spectral method at preset time intervals or at each cooking stage, and transmit the result to the control unit (2). Accordingly, the control unit (2) can control the cooking robot (1) by monitoring changes in sugar content in real time.
[0074] At this time, the non-contact sugar content meter (121) can perform three consecutive measurements and calculate the average of the three measured sugar content values as the final sugar content value.
[0075] Additionally, the non-contact sugar content meter (121) can be manufactured in a preset size so as not to interfere with the cooking operation of the robot arm (11) when mounted on the robot arm (11).
[0076] For example, the measurable sugar content range of the non-contact sugar content meter (121) is 0 to 80 Brix, and can be measured with high accuracy of ±0.5 Brix. Also, the power consumption of the non-contact sugar content meter (121) is designed to be 5W or less, so that it can operate stably even in the limited power environment of a food truck (FT).
[0077] FIG. 3 is a conceptual diagram schematically illustrating a non-contact sugar content measuring instrument according to an embodiment of the present invention.
[0078] Referring to FIG. 3, the non-contact sugar content meter (121) may include a light source unit (121A), a light receiving unit (121B), a spectroscopic unit (121C), a calculation unit (121D), and a distance sensor (121E).
[0079] The light source (121A) can irradiate food with near-infrared rays in a wavelength range of 900 nm or more and 1700 nm or less.
[0080] For example, the light source (121A) may be composed of an array of LEDs having different wavelengths of 900 nm, 1200 nm, 1450 nm, and 1700 nm. At this time, the LEDs may be lit sequentially to irradiate near-infrared light onto food.
[0081] The light receiving unit (121B) can receive near-infrared rays reflected from food.
[0082] More specifically, near-infrared light reflected from food is collected in a light receiving unit (121B) composed of an InGaAs photodiode, and unwanted wavelengths can be removed through a broadband interference filter.
[0083] The spectroscopic unit (121C) can analyze the spectrum after removing noise from the spectrum of the received near-infrared light.
[0084] For example, the spectroscopic unit (121C) may be a diffraction grating spectrometer.
[0085] The calculation unit (121D) can calculate the sugar content value by comparing the analyzed spectrum with the previously stored calibration curve data and transmit the result to the control unit (2).
[0086] For example, the analyzed spectrum can be converted into a sugar content value in a computation unit (121D) equipped with an ARM Cortex-M4 processor.
[0087] The distance sensor (121E) can measure the distance between the non-contact sugar content meter (121) and the food.
[0088] Accordingly, the light source unit (121A) can adjust the output of near-infrared light according to the distance value measured by the distance sensor (121E).
[0089] For example, the distance sensor (121E) can measure the distance to the food using the TOF method.
[0090] FIG. 4 is a schematic diagram showing an angle adjustment unit according to an embodiment of the present invention.
[0091] Referring to FIGS. 2 and FIGS. 4, the angle adjustment unit (122) is installed on the outer surface of the robot arm (11) and can adjust the position and measurement angle of the non-contact sugar content meter (121).
[0092] The angle adjustment unit (122) may include a first angle adjustment unit (122A) and a second angle adjustment unit (122B).
