Description

Technical Field

[0001] This application relates to the field of food storage technology, such as a method, apparatus, and storage equipment for decomposing pesticide residues on the surface of food ingredients. Background Technology

[0002] During food production, pesticide residues are generated, causing numerous health problems and posing significant risks to humans. Ordinary water washing is far from sufficient to remove pesticide residues, heavy metals, and insect eggs from the surface of food. Currently, methods for removing bacteria and pesticide residues mainly rely on high temperatures, chemical cleaning agents, and irradiation. However, high temperatures can damage the nutrients in agricultural products, chemical cleaning agents pose environmental problems, and irradiation is costly and leaves residues. Therefore, new technologies such as ultrasound, ultraviolet light, and ozone are being applied to the cleaning, sterilization, and pesticide residue removal processes. Ultrasonic cleaning technology is now widely used in industrial products and medical devices. Ozone and ultraviolet light technologies are primarily used for air disinfection and process water disinfection in hospital wards, food factories, and pharmaceutical plants. Consequently, devices such as ozone water cleaning, ozone generators, and ultraviolet lamps have emerged to treat food.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] When using ozone water for cleaning or an ozone generator to treat food, the ozone concentration cannot be reached during space circulation to remove pesticide residues; when using ultraviolet lamps to treat food, only one side of the food is irradiated; therefore, the effect of removing pesticide residues from food is not good and does not meet customer needs. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a method, apparatus, and storage device for decomposing pesticide residues on the surface of food ingredients, thereby solving the technical problem that a single device is not effective in removing pesticide residues from food ingredients and cannot meet customer needs.

[0007] In some embodiments, the method for decomposing pesticide residues on the surface of food is applied to a storage device having a containment cavity. The method includes: determining the humidity of the containment cavity; when the humidity of the containment cavity is less than or equal to a first preset humidity, activating a first wavelength ultraviolet light and a second wavelength ultraviolet light to irradiate the food in the containment cavity; and when the irradiation duration meets a first preset condition, turning off the first wavelength ultraviolet light and the second wavelength ultraviolet light; wherein the second wavelength ultraviolet light excites the air to generate ozone to decompose pesticide residues on the surface of the food to be treated.

[0008] In some embodiments, the apparatus for decomposing pesticide residues on the surface of food includes: a processor and a memory storing program instructions, the processor being configured to execute, when executing the program instructions, the method for decomposing pesticide residues on the surface of food as provided in the foregoing embodiments.

[0009] In some embodiments, the storage device includes an apparatus for decomposing pesticide residues on the surface of food, as provided in the foregoing embodiments.

[0010] The method, apparatus, and storage device for decomposing pesticide residues on the surface of food provided in this disclosure can achieve the following technical effects:

[0011] When humidity conditions are met, a first wavelength of ultraviolet light and a second wavelength of ultraviolet light are simultaneously irradiated into the storage device. The first wavelength of ultraviolet light directly irradiates the food to be treated, causing pesticide molecules on the surface of the food that are sensitive to the first wavelength of ultraviolet light to be continuously decomposed. Meanwhile, the second wavelength of ultraviolet light can excite the air to produce ozone. The first wavelength of ultraviolet light can directly decompose pesticide residues on the surface of the food, and the ozone continuously diffuses in the storage device to decompose pesticide residues on the surface of the food. The two work together to treat the food, which improves the efficiency of removing pesticide residues from the food and makes it more practical.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0024] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0025] Figure 1This is a schematic diagram of a device for decomposing pesticide residues on the surface of food provided in an embodiment of this disclosure; Figure 2 This is a structural schematic diagram of a top cover plate provided in an embodiment of this disclosure. (In conjunction with...) Figure 1 , Figure 2 As shown, a device for decomposing pesticide residues on the surface of food is installed within the storage cavity of a storage device. The cavity is enclosed by a fixedly connected top cover plate 110, bottom cover plate 120, rear side plate 130, first side plate 140, and second side plate 150. An open-top storage box 160 for placing food is provided within the cavity. The storage box 160 can be pulled out or pushed back into the cavity. When pushed back into the cavity, the storage box 160 is in communication with the cavity. A lamp groove 111 is provided on the side of the top cover plate 110 facing the cavity, and a dual-wavelength ultraviolet cold cathode lamp 200 is installed within the lamp groove 111. The dual-wavelength ultraviolet cold cathode lamp 200 can simultaneously irradiate a first wavelength of ultraviolet light and a second wavelength of ultraviolet light. The first wavelength of ultraviolet light continuously decomposes pesticide molecules on the surface of the food that are sensitive to the first wavelength of ultraviolet light, while the second wavelength of ultraviolet light excites the air to produce ozone, which continuously diffuses within the cavity to decompose pesticide residues on the surface of the food. Optionally, a protective cover is provided on the lamp trough 111 to cover the dual-wavelength ultraviolet cold cathode lamp tube 200 for the purpose of protecting the dual-wavelength ultraviolet cold cathode lamp tube 200.

[0026] Optionally, the dual-wavelength ultraviolet cold cathode lamp 200 is positioned at the geometric center of the top cover plate 110 and parallel to the side of the top cover plate 110. This maximizes the irradiation range of the dual-wavelength ultraviolet cold cathode lamp 200 and reduces blind spots.

[0027] Optionally, the top cover 110 may be made of aluminum plate or have an aluminum coating on its surface. This allows it to reflect the light emitted by the dual-wavelength ultraviolet cold cathode lamp 200, improving the irradiation effect and increasing the irradiation range.

[0028] Optionally, the storage box 160 is made of 304 stainless steel. This allows it to come into direct contact with food and reflects the light emitted by the dual-wavelength ultraviolet cold cathode lamp 200, improving the irradiation effect and increasing the irradiation range.

[0029] Optionally, a fan 300 is also provided on the side wall of the light trough 111. The fan 300 has an air inlet 310 and a return air inlet 410 on the side of the rear side plate 130 facing the receiving cavity. The air inlet 310 and the return air inlet 410 are connected by a circulating air duct.

[0030] Optionally, the storage box 160 has an opening 162 on the first side wall 161 near the rear side panel 130 that corresponds to the return air vent 410. In this way, when the storage box 160 is completely inside the receiving cavity, turning on the fan 300 can enable the gas inside the receiving cavity to circulate rapidly through the air inlet 310 and the return air vent 410.

[0031] Optionally, an ozone purification module is installed at the return air vent 410 to reduce the ozone concentration in the containment cavity.

[0032] Optionally, the bottom of the storage box 160 is provided with a storage plate with a grid. This facilitates the flow of air around the food placed inside the cavity, improving the effect of removing pesticide residues from the surface of the food.

[0033] Optionally, a low-temperature plasma generator is installed inside the storage box, which, in conjunction with a dual-wavelength ultraviolet cold cathode lamp, simultaneously generates ultraviolet light with a wavelength range of 200–280 nm and ultraviolet light with a wavelength range of 160–200 nm. The low-temperature plasma generator and the dual-wavelength ultraviolet cold cathode lamp have a complementary effect on removing pesticide residues from food. The ultraviolet light with a wavelength range of 200–280 nm can continuously decompose photosensitive pesticide molecules, while the ultraviolet light with a wavelength range of 160–200 nm can excite the air to produce ozone, thus decomposing residual pesticides on the surface of the food. The low-temperature plasma generator can also treat ion-sensitive pesticides, thereby achieving the decomposition and treatment of multiple types of pesticides and significantly improving the effectiveness of removing pesticide residues from the surface of food.

[0034] Optionally, a low-temperature plasma generator and a single-wavelength ultraviolet cold cathode lamp capable of generating ultraviolet light with a wavelength range of 200–280 nm can be installed inside the storage box to treat pesticides on the surface of the food.

[0035] Optionally, a single-wavelength ultraviolet cold cathode lamp and an ozone generator capable of generating ultraviolet light with a wavelength range of 200–280 nm can be installed inside the storage box to treat pesticides on the surface of the food.

[0036] Figure 3 This is a schematic diagram of a method for decomposing pesticide residues on the surface of food provided in an embodiment of this disclosure. (Combined with...) Figure 3 As shown, this disclosure provides a method for decomposing pesticide residues on the surface of food, applied to a storage device with a receiving cavity, the method comprising:

[0037] S10, determine the humidity of the receiving cavity.

[0038] S20, when the humidity of the container cavity is less than or equal to the first preset humidity, the first wavelength ultraviolet light and the second wavelength ultraviolet light are activated to irradiate the food in the container cavity.

[0039] S30, if the irradiation duration meets the first preset condition, turn off the first wavelength ultraviolet light and the second wavelength ultraviolet light.

[0040] The second wavelength of ultraviolet light excites the air to produce ozone, which decomposes pesticide residues on the surface of the food being treated.

[0041] In this way, the first wavelength of ultraviolet light can continuously decompose pesticide molecules on the surface of the food being treated that are sensitive to the first wavelength of ultraviolet light, and the second wavelength of ultraviolet light can excite the air to produce ozone, which continuously diffuses in the containment cavity to decompose residual pesticides on the surface of the food, thereby achieving the purpose of decomposing residual pesticides on the surface of the food.

[0042] Optionally, the wavelength range of the first wavelength ultraviolet light is 200–280 nm; the wavelength range of the second wavelength ultraviolet light is 160–200 nm.

[0043] Optionally, a humidity sensor is installed inside the storage cavity. When the user selects to start pesticide residue removal treatment for the food, the ambient humidity inside the storage cavity is detected, i.e., the ambient humidity inside the storage box is detected. A first preset humidity is used as a standard to measure the ambient humidity inside the storage cavity. When the ambient humidity inside the storage cavity is less than or equal to the first preset humidity, it is considered that the ambient humidity inside the storage cavity is suitable for pesticide residue removal treatment of the food, and the first wavelength ultraviolet light and the second wavelength ultraviolet light are activated to irradiate the food stored in the storage cavity; when the ambient humidity inside the storage cavity is greater than the first preset humidity, it is considered that the ambient humidity inside the storage cavity is too high. Optionally, the humidity sensor is embedded in the top cover plate. This way, it does not affect the storage box being pulled out or pushed back.

[0044] Optionally, a dehumidification module is provided inside the receiving cavity. The method for decomposing pesticide residues on the surface of food provided in this embodiment further includes:

[0045] If the humidity in the containment chamber is greater than the first preset humidity, the dehumidification module will be activated.

[0046] By activating the dehumidification module, the ambient humidity inside the storage cavity is reduced, thereby reducing the humidity inside the storage box and preventing a damp environment from weakening the efficiency of pesticide residue removal.

[0047] Optionally, the first preset humidity value ranges from 80% to 90%, for example, the first preset humidity can be 80%, 85%, or 90%. Optionally, the first preset humidity is relative humidity, and the humidity of the environment inside the container is compared with the first preset humidity to determine the level of humidity inside the container, and further control is performed based on the comparison result. Optionally, the dehumidification module is embedded in the top cover plate. This does not affect the storage box being pulled out or pushed back.

[0048] In some embodiments, a method for decomposing pesticide residues on the surface of food ingredients is applied to a storage device with a receiving cavity, comprising: activating a first wavelength ultraviolet light and a second wavelength ultraviolet light to irradiate the food ingredients inside the receiving cavity; and, if the irradiation duration meets a first preset condition, turning off the first wavelength and the second wavelength ultraviolet light. The second wavelength ultraviolet light excites the air to generate ozone to decompose pesticide residues on the surface of the food ingredients to be treated. Thus, when a user selects to begin pesticide residue removal treatment of the food ingredients, the first and second wavelength ultraviolet lights are directly activated to treat the food ingredients, ensuring the effectiveness of pesticide residue removal and improving the efficiency of pesticide residue removal.

[0049] The method for decomposing pesticide residues on the surface of food provided in this disclosure, under suitable humidity conditions, involves simultaneously irradiating the storage device with a first wavelength of ultraviolet light and a second wavelength of ultraviolet light. The first wavelength of ultraviolet light directly irradiates the food to be treated, enabling the continuous decomposition of pesticide molecules on the surface of the food that are sensitive to the first wavelength of ultraviolet light. The second wavelength of ultraviolet light excites the air to produce ozone. The first wavelength of ultraviolet light directly decomposes pesticide residues on the surface of the food, and the ozone continuously diffuses within the storage device to decompose pesticide residues on the surface of the food. The first and second wavelengths of ultraviolet light work together to treat the food, improving the efficiency of pesticide residue removal and enhancing practicality. Optionally, the first preset condition includes an irradiation duration greater than or equal to a first preset duration. Optionally, the first preset duration ranges from 60s to 180s to prevent damage to the food from either the first or second wavelength of ultraviolet light. For example, the first preset duration can be 60s, 90s, 120s, 150s, or 180s.

[0050] Figure 4 This is a schematic diagram of another method for decomposing pesticide residues on the surface of food provided in this disclosure. (Combined with...) Figure 4 As shown, in some embodiments, the method for decomposing pesticide residues on the surface of food ingredients further includes:

[0051] S31, turn off the first wavelength ultraviolet light and the second wavelength ultraviolet light for the second preset time.

[0052] S32 periodically turns the first wavelength ultraviolet light and the second wavelength ultraviolet light on and off.

[0053] After a second preset time period following the shutdown of the first and second wavelength ultraviolet lamps, the first and second wavelength ultraviolet lamps are periodically turned on and off. This intermittent activation of the first and second wavelength ultraviolet lamps allows for multiple irradiations of the food being treated, improving the efficiency of pesticide residue removal. Furthermore, it prevents prolonged irradiation by the first and second wavelength ultraviolet lamps from affecting the health of the food, thus improving its quality.

[0054] Optionally, the second preset duration can be in the range of 20s to 120s. For example, the second preset duration can be 20s, 50s, 80s, 100s, or 120s.

[0055] Figure 5 This is a schematic diagram illustrating the periodic activation and deactivation of a first wavelength ultraviolet light and a second wavelength ultraviolet light, as provided in an embodiment of this disclosure. (In conjunction with...) Figure 5 As shown, optionally, periodically turning on and off the first wavelength ultraviolet light and the second wavelength ultraviolet light includes:

[0056] S321, activate the first wavelength ultraviolet light and the second wavelength ultraviolet light for the third preset duration.

[0057] S322, turn off the first wavelength ultraviolet light and the second wavelength ultraviolet light for the fourth preset time.

[0058] After the first and second wavelength ultraviolet lamps are activated for a third preset time, they are turned off for a fourth preset time, allowing ozone within the containment chamber to diffuse and improving the removal of pesticide residues. Furthermore, intermittently activating the first and second wavelength ultraviolet lamps reduces energy consumption and extends the lifespan of the dual-wavelength ultraviolet lamps.

[0059] Optionally, the third preset duration can range from 5s to 90s. For example, the third preset duration can be 5s, 10s, 20s, 50s, 70s, or 90s. Optionally, the fourth preset duration can range from 5s to 150s. For example, the fourth preset duration can be 5s, 10s, 20s, 50s, 80s, 120s, or 150s.

[0060] Optionally, the first preset duration is longer than the third preset duration, and the second preset duration is longer than the fourth preset duration. In this way, irradiating the food to be treated with the first wavelength ultraviolet light and the second wavelength ultraviolet light for the first preset duration can fully activate the dual ultraviolet wavelength lamps, enabling them to reach the maximum light intensity, thereby achieving the purpose of decomposing pesticide residues on the surface of the food.

[0061] Optionally, if the number of times the first wavelength ultraviolet light and the second wavelength ultraviolet light are periodically turned on and off meets a preset threshold, the irradiation of the food in the containment cavity is terminated.

[0062] Optionally, the preset number of times threshold can be set at the factory based on experimental data. Optionally, the preset number of times threshold can be set by the user according to the setting value recommended by the manufacturer. Optionally, the range of the preset number of times threshold is 5 to 40 times, for example, the preset number of times threshold can be 5 times, 10 times, 20 times, 35 times or 40 times.

[0063] Optionally, an ozone concentration sensor is installed inside the containment cavity. The ozone concentration inside the containment cavity is detected each time the first and second wavelength ultraviolet lamps are turned off. If the ozone concentration reaches a preset value, irradiation of the food inside the containment cavity is stopped, and the first and second wavelength ultraviolet lamps are no longer turned on. Optionally, the preset ozone concentration range is 0.2 mg / m³. 3 ~3.0mg / m 3 For example, the preset value for ozone concentration could be 0.2 mg / m³. 3 0.5 mg / m 3 1.0 mg / m 3 2.0 mg / m 3 Or 3.0 mg / m 3 .

[0064] Optionally, an ozone concentration sensor and an oxygen concentration sensor are installed inside the containment cavity. After each time the first wavelength ultraviolet light and the second wavelength ultraviolet light are turned off, the ozone and oxygen concentrations inside the containment cavity are detected, and the ratio of ozone to oxygen concentration is calculated. When the ozone and oxygen concentrations reach a preset ratio, irradiation of the food inside the containment cavity is stopped, and the first and second wavelength ultraviolet lights are no longer turned on. The preset ratio of ozone to oxygen concentration ranges from 1:100 to 1:5; for example, the preset ratio of ozone to oxygen concentration can be 1:100, 1:50, 1:25, 1:10, or 1:5.

[0065] Figure 6 This is a schematic diagram of another method for decomposing pesticide residues on the surface of food provided in this disclosure. (Combined with...) Figure 6 As shown, in some embodiments, the method for decomposing pesticide residues on the surface of food ingredients further includes:

[0066] S41, stop irradiating the food in the container cavity, and stop turning on the first wavelength ultraviolet light and the second wavelength ultraviolet light.

[0067] S42, activate the ozone purification module.

[0068] The irradiation of the food inside the container is terminated, indicating that the decomposition of pesticide residues on the food surface has been completed. At this point, the ozone concentration inside the container may be higher than the safe concentration. Opening the air inlet, air outlet, and fan allows the gas inside the container to pass through the ozone purification module, reducing the ozone concentration to a preset threshold. This prevents damage or harm to the respiratory or nervous systems from high concentrations of ozone when the user opens the storage device. Optionally, the preset ozone concentration threshold range is 0.05 mg / m³. 3 ~0.21mg / m 3 For example, the preset concentration threshold for ozone could be 0.05 mg / m³. 3 0.10 mg / m 3 0.15mg / m 3 Or 0.21 mg / m 3 .

[0069] Optionally, the ozone purification module can be an ozone-removing filter, installed in the circulating air duct between the air inlet and the air outlet. In this way, after the irradiation of the food in the containment cavity is stopped, and the first and second wavelength ultraviolet lamps are no longer turned on, the air inlet, air outlet, and fan are turned on. This allows the gas in the containment cavity to be reduced and decomposed as it passes through the ozone-removing filter, thereby reducing the ozone concentration to a preset concentration threshold.

[0070] In some embodiments, the storage device further includes a self-locking device disposed at the opening and closing point of the storage device. Before activating the first wavelength ultraviolet light and the second wavelength ultraviolet light to irradiate the food in the containing cavity, the method for decomposing pesticide residues on the surface of the food provided in this embodiment further includes:

[0071] The self-locking device is activated to seal the receiving cavity.

[0072] This prevents the storage device from being opened due to user error or other reasons after the first and second wavelengths of ultraviolet light are activated, thus preventing ultraviolet and ozone leakage from harming the human body and improving the safety of the storage device.

[0073] Optionally, a power-off sensing device is installed inside the storage cavity, electrically connected to a dual-wavelength ultraviolet cold cathode lamp, to detect whether the storage device has been opened. When the power-off sensing device detects that the storage device has been opened, the dual-wavelength ultraviolet cold cathode lamp is de-energized to prevent ultraviolet leakage from harming the human body and to improve the safety of the storage device.

[0074] Optionally, the first and second wavelength ultraviolet (UV) lights can be simultaneously activated or deactivated by turning the dual-wavelength UV cold cathode lamp on or off. The dual-wavelength UV cold cathode lamp is housed inside the receiving cavity. This allows for the stable simultaneous irradiation of both wavelengths of UV light by a single dual-wavelength UV cold cathode lamp, resulting in a simple structure and easy control. Furthermore, the energy-saving and long-life characteristics of the dual-wavelength UV cold cathode lamp improve the energy efficiency and practicality of the storage device.

[0075] This disclosure also provides an apparatus for decomposing pesticide residues on the surface of food, including a processor and a memory storing program instructions. The processor is configured to execute the method for decomposing pesticide residues on the surface of food as claimed in any one of the claims when executing the program instructions.
