Description

Technical Field

[0001] This invention relates to a batch simulation testing device and method for food probes, belonging to the field of batch simulation testing and quality inspection technology for food probes. Background Technology

[0002] In existing technologies, food probes require batch testing after production. Currently, food probes need to undergo testing steps such as potato testing and pork testing to simulate actual working conditions. This testing method has many drawbacks: The operation process is relatively complex and relies on manual labor, so only random sampling can be used, and full testing and inspection cannot be achieved. Purchasing food items such as potatoes and pork resulted in high testing costs. Food probes leave traces of use after testing, which are difficult to clean and are detrimental to actual production and shipment.

[0003] Therefore, existing technologies have shortcomings and need further improvement and refinement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a batch simulation testing device and method for food probes. According to an embodiment of the present invention, a first embodiment is provided: a batch simulation testing device for food probes, comprising: The outer casing includes a second cavity, and the second outer casing is equipped with a second temperature control device. The second temperature control device is used to control the temperature change of the second cavity to simulate the internal temperature change of the heating device where the food probe is located. A movable inner box includes a first cavity filled with a liquid medium. The movable inner box is equipped with a first temperature control device for controlling the temperature change of the liquid medium to simulate the internal temperature change of food when a food probe is inserted. The boiling temperature of the liquid medium is configured to limit the upper limit of the internal temperature of the food. The outer casing is provided with a second heat insulation layer to isolate the temperature exchange between the surrounding environment and the second cavity; the movable inner casing is provided with a first heat insulation layer to isolate the temperature exchange between the second cavity and the first cavity. The movable inner box is equipped with a surface heat insulation plate on the top, and the surface heat insulation plate has multiple test holes for inserting food probes.

[0005] Furthermore, the movable inner box also includes a first metal box and a bottom heat insulation board; a first heat insulation layer is provided in the first metal box to prevent heat from being transferred from the second cavity to the first cavity; the bottom heat insulation board is used to prevent heat from being transferred from the bottom of the outer box to the first cavity; the surface heat insulation board is used to reduce the amount of liquid medium that is transferred from the second cavity to the first cavity and to reduce the evaporation of the liquid medium.

[0006] Furthermore, the surface heat insulation plate is evenly arranged with multiple test holes into which food probes can be inserted.

[0007] Furthermore, the surface insulation panel is fixed to the movable inner box by a metal cap, and a sealing structure is provided between the metal cap and the surface insulation panel.

[0008] Furthermore, the surface insulation plate is also provided with a medium supply hole, which is used to replenish liquid medium and to release pressure from the first chamber during testing.

[0009] Furthermore, the movable inner tank includes an observation window and a liquid level float, through which the liquid level float can be observed and the height of the liquid medium can be confirmed.

[0010] Furthermore, the outer casing also includes a second metal casing; a second heat insulation layer is provided inside the second metal casing to prevent heat from being transferred from the second cavity to the surrounding environment.

[0011] Furthermore, the top of the second metal housing is provided with an exhaust port, which is used to discharge the evaporated liquid medium and is also used to place an external temperature probe for monitoring the temperature of the second chamber.

[0012] Furthermore, the outer casing also includes an equipment door, which allows for the insertion or removal of a movable inner casing when opened.

[0013] According to an embodiment of the present invention, utilizing the batch simulation testing device for food probes in the first embodiment of the present invention, a second embodiment is provided as follows: A batch simulation testing method for food probes includes the following steps: Inject liquid medium into the movable inner tank until the liquid level float reaches the preset height; Multiple food probes are inserted into the liquid medium through the test holes of the surface heat insulation plate; Move the movable inner box into the second cavity of the outer box and close the equipment door of the outer box; The second temperature control device is activated to control the temperature of the second cavity to the preset heating device temperature curve, and the first temperature control device is activated to control the temperature of the first cavity to the preset food internal temperature curve. After the test, remove the movable inner box, take out the food probe, clean up any liquid residue, and complete the food probe quality inspection.

[0014] Compared with the prior art, the unique advantages of the technical solution provided in this application are as follows: This invention uses independent temperature control in the first and second cavities to accurately simulate the real scenario of a food probe being inserted into food inside a heating device, and the first cavity of the movable inner box simulates the upper limit of the internal temperature of the food through the boiling temperature of the liquid medium.

[0015] With multiple test holes set on the surface heat insulation plate, 8*12 food probes can be tested simultaneously under the same test environment, and all quality inspection tests after the food probes are produced can be realized through efficient and rapid testing methods. Traditional food probe testing methods have a core challenge: ensuring that the temperature of the probe body does not get too high to avoid internal component failure, while simultaneously controlling the temperature of the handle to be much higher than that of the probe body. Even a slight error in the control process can easily lead to overheating of the probe body. This solution places the probe body in a liquid medium, which can achieve a stable temperature control process and utilize the boiling characteristics of the liquid medium to ensure that the upper limit of the internal temperature of the food remains constant at the boiling point threshold, thus avoiding failure of the internal components of the food probe due to excessively high test temperatures. After the test, the food probe showed no change in appearance, was easy to clean, and had no food residue or oil residue, making it suitable for use in quality inspection processes in actual production. This device can perform simulation tests in multiple scenarios with a single unit, making it widely applicable.

[0016] Therefore, this invention provides a temperature control simulation device that supports custom temperature curves, which can simulate the heating scenarios of heating devices such as gas ovens, electric ovens, and microwave ovens. It is compatible with the testing needs of most existing food probes. A single device can realize traditional testing devices for multiple scenarios. Through four technological innovations, namely accurate simulation, low-cost testing, efficient batch testing, and high safety, it significantly improves the industrialization level of food probe production and testing, and has extremely strong market application value.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example 1 This embodiment provides a batch simulation testing device for food probes to replace existing traditional food probe testing methods and devices. It addresses the shortcomings of existing testing devices, such as reliance on manual operation, low efficiency, inability to achieve full inspection and testing, the need for testing consumables (including potatoes and pork), leading to high testing costs, and the presence of residues that are difficult to clean. Particularly concerning is the need for temperature control, requiring a two-stage temperature control system where the probe body 32 temperature cannot be too high (simulating the temperature of the probe body 32 inserted into the food) and the handle 31 temperature must be significantly higher than the probe body 32 temperature (simulating the internal ambient temperature of an oven's heating element). Precise temperature control of the probe body 32 is crucial to prevent overheating and subsequent failure of internal components. Traditional solutions require a series of measures, including temperature monitoring, high-temperature warning alarms, and overheat power-off, to ensure the probe body 32 temperature does not exceed the upper limit, resulting in high testing costs.

[0022] To address the aforementioned issues, this embodiment provides a batch simulation testing device for food probes, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: The outer casing 20 includes a second cavity 21. The second outer casing 20 is equipped with a second temperature control device, which is used to control the temperature change of the second cavity 21 to simulate the internal temperature change of the heating device where the food probe is located. The outer casing 20 is used to simulate the ambient temperature inside an oven and can be formed by welding stainless steel plates. The outer casing 20 forms a closed second cavity 21, which can accommodate at least one movable inner casing 10. The second temperature control device uses a temperature control instrument in conjunction with a heating plate 28 to achieve heating. The heating plate 28 is arranged at the bottom of the support plate on which the movable inner casing 10 is placed. A second temperature control operation panel 26 is also provided on the surface of the second metal casing 22 to display temperature parameters and control buttons.

[0023] The movable inner box 10 includes a first cavity 11 filled with a liquid medium. The movable inner box 10 is equipped with a first temperature control device, which is used to control the temperature change of the liquid medium to simulate the internal temperature change of the food when a food probe is inserted. The boiling temperature of the liquid medium is configured to limit the upper limit of the internal temperature of the food. The first metal box 13 of the movable inner box 10 can be formed by welding stainless steel plate. The interior of the movable inner box 10 is a first cavity 11, which can be injected with a liquid medium, usually water.

[0024] The outer casing 20 is provided with a second heat insulation layer to isolate the temperature exchange between the surrounding environment and the second cavity 21; the movable inner casing 10 is provided with a first heat insulation layer to isolate the temperature exchange between the second cavity 21 and the first cavity 11. The movable inner box 10 is provided with a surface heat insulation plate 12 on the top, and the surface heat insulation plate 12 is provided with a plurality of test holes 121 for inserting food probes.

[0025] Specifically, the outer casing 20 includes a second metal casing 22. An equipment door 24 is provided on the front of the second metal casing 22. When the equipment door 24 is opened, at least one movable inner casing 10 can be inserted or removed. The inner wall of the second metal casing 22 is provided with a heat-insulating inner liner. The side wall of the second metal casing 22 is filled with a second heat-insulating layer. A support plate is provided at the bottom of the second metal casing 22 for placing the movable inner casing 10. The heating plate 28 of the second temperature control device can be placed at the bottom of the support plate.

[0026] Specifically, the control range of the second temperature control device is 20-250℃, and the heating rate is adjustable within 0-20℃ / min. The second metal box 22 is also equipped with a blower 25, such as an axial flow fan, to achieve uniform temperature in the second cavity 21. The maximum air volume of the axial flow fan is 150m³ / h. The top of the second metal box 22 is also equipped with an exhaust port 23 for exhausting the vapor of the evaporating liquid medium. The second metal box 22 is also equipped with a K-type thermocouple in the second cavity 21 to provide real-time feedback on the temperature of the second cavity 21.

[0027] Specifically, a viewing window 27 is provided on the equipment door 24, which can observe the status of the handles 31 of all food probes during the test.

[0028] Specifically, the movable inner box 10 includes a first metal box 13, a bottom heat insulation board 14, and a surface heat insulation board 12. The first metal box 13 is provided with a first heat insulation layer to prevent heat from being transferred from the second cavity 21 to the first cavity 11. The bottom heat insulation board 14 is used to prevent heat from being transferred from the bottom of the outer box 20 to the first cavity 11. The surface heat insulation board 12 is used to reduce the transfer of heat from the second cavity 21 to the liquid medium in the first cavity 11 and to reduce the evaporation of the liquid medium.

[0029] The liquid medium can be either deionized water or glycerol aqueous solution. Deionized water has a boiling point of 100°C, simulating the upper limit of the internal temperature of ordinary food. Glycerol aqueous solution has a concentration of 50% and a boiling point of 120°C, making it suitable for high-temperature food scenarios.

[0030] A downward-facing transparent straight tube is provided on the surface insulation plate 12. A liquid level float 16 is placed inside the transparent straight tube. An observation window is provided on the side of the first metal box 13 to observe the height of the liquid level float 16 inside the transparent straight tube. The upper opening of the transparent straight tube is the medium supply hole 122, which is used to replenish the liquid medium.

[0031] Specifically, multiple test holes are evenly opened on the surface heat insulation plate 12, for example, it can be set to 8*12 test holes 121 with a hole diameter of 8mm to accommodate food probes with a diameter of 5-7mm. Specifically, the top of the movable inner box 10 is secured to the first metal box 13 by four metal buckles 151 and a metal cover 15. A silicone sealing ring is also provided between the metal cover 15 and the first metal box 13 to prevent media leakage.

[0032] The present invention uses the independent temperature control of the first cavity 11 and the second cavity 21 to accurately simulate the real scenario of a food probe being inserted into the food in the heating device, and the first cavity 11 of the movable inner box 10 simulates the upper limit of the internal temperature of the food by the boiling temperature of the liquid medium. Through multiple test holes 121 set on the surface heat insulation plate 12, 8*12 food probes can be tested simultaneously under the same testing environment. This efficient and rapid testing method enables all quality inspection tests after the food probes are produced. A core challenge of traditional food probe testing methods is ensuring that the temperature of the probe body 32 does not become too high to avoid internal component failure, while simultaneously controlling the temperature of the handle 31 to be much higher than the probe body 32. Even slight errors in the control process can easily lead to overheating of the probe body 32. In this solution, the probe body 32 is placed in a liquid medium, achieving a stable temperature control process. Furthermore, the boiling characteristics of the liquid medium ensure that the upper limit of the food's internal temperature remains constant at the boiling point threshold, preventing failure of the internal components due to excessively high testing temperatures. After testing, the food probes show no change in appearance, are easy to clean, and have no food residue or oil residue, making them suitable for quality inspection processes in actual production. This device can perform simulated testing in multiple scenarios with a single unit, making it widely applicable.

[0033] Therefore, this invention provides a temperature control simulation device that supports custom temperature curves, which can simulate the heating scenarios of heating devices such as gas ovens, electric ovens, and microwave ovens. It is compatible with the testing needs of most existing food probes. A single device can realize traditional testing devices for multiple scenarios. Through four technological innovations, namely accurate simulation, low-cost testing, efficient batch testing, and high safety, it significantly improves the industrialization level of food probe production and testing, and has extremely strong market application value.

[0034] Example 2 This embodiment provides a batch simulation testing device for food probes that is more suitable for industrialized production lines, including an outer box 20, a movable inner box 10, and a conveying device. The movable inner box 10 is heated to the simulated internal temperature of food by a front heating device. The movable inner box 10 includes a first cavity 11, which is filled with a liquid medium. The movable inner box 10 is equipped with a first temperature control device, which is used to control the temperature change of the liquid medium to simulate the internal temperature change of food when a food probe is inserted. The boiling temperature of the liquid medium is configured to limit the upper limit of the internal temperature of the food. The second cavity 21 of the outer casing 20 is provided with at least three temperature gradient stages along the conveying device. The conveying device conveys the movable inner casing 10 through the at least three temperature gradient stages of the second cavity 21 of the outer casing 20 to simulate the internal temperature change of the heating device.

[0035] Compared to Embodiment 1, the solution in this embodiment has a faster testing speed, can be adapted to existing production lines, and can complete production and quality inspection in one go, greatly improving processing efficiency and reducing testing costs.

[0036] Example 3 like Figure 4 As shown, a batch simulation testing method for food probes includes the following steps: S10: Inject liquid medium into the movable inner tank 10 until the liquid level float 16 reaches the preset height; S20: Insert multiple food probes into the liquid medium through the test holes 121 of the surface heat insulation plate 12; S30: Move the movable inner box 10 into the second cavity 21 of the outer box 20 and close the equipment door 24 of the outer box 20; S40: Start the second temperature control device to control the temperature of the second cavity 21 to the preset heating device temperature curve, and start the first temperature control device to control the temperature of the first cavity 11 to the preset food internal temperature curve. S50: After the test, remove the movable inner box 10, remove the food probe to clean up any liquid residue, and complete the food probe quality inspection.

[0037] The present invention uses the independent temperature control of the first cavity 11 and the second cavity 21 to accurately simulate the real scenario of a food probe being inserted into the food in the heating device, and the first cavity 11 of the movable inner box 10 simulates the upper limit of the internal temperature of the food by the boiling temperature of the liquid medium.
