Technical Field
[0001] The present invention relates to the technical field of fruit and vegetable cleaning, and in particular to a device for degrading pesticide residues on fruits and vegetables, which uses a high-efficiency, low-power power supply to drive pollution-free cracking electrodes to generate hydroxyl radicals (·OH) to degrade pesticide residues on the surface of fruits and vegetables. Background Art
[0002] As people continue to pursue healthier lives, the degradation of pesticide residues in fruits and vegetables is becoming increasingly urgent. The long-term accumulation of pesticide residues in the human body can easily lead to tumor formation, contributing to an increasing number of cancer patients. Hydroxyl radical (.OH) degradation of pesticide residues is the most effective method, but traditional equipment uses a DC electric field, which consumes large amounts of power and is inefficient, making it expensive and hindering rapid adoption. Some large-scale fruit and vegetable cleaning equipment is not only expensive, but also inefficient and energy-intensive, making it prohibitive for large-scale use. Summary of the Invention
[0003] In view of this, the present invention proposes a fruit and vegetable pesticide residue degradation device to solve the problems existing in the technical background. The specific contents include the following:
[0004] A device for degrading pesticide residues in fruits and vegetables includes a cabinet connected to a plurality of electrodes via connecting wires. The cabinet has a built-in high-efficiency, low-power power supply, which includes a pulse generator and a pulse power amplifier. The electrodes are pollution-free lysis electrodes placed in a water tank. The cabinet is provided with a switch array for controlling the on and off of the electrode working group.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0013] See also Figure 1 The illustrated device for degrading pesticide residues in fruits and vegetables includes a cabinet 1, which houses a high-efficiency, low-power power supply 3. This power supply 3 includes a pulse generator and a pulse power amplifier, converting 220V AC power into high-efficiency pulse signals. The cabinet 1 is connected to multiple electrodes 5 via connecting wires 4. These electrodes 5 are non-polluting, made of inert materials and can be fixed in a water tank. A switch array 2 is located on the surface of the cabinet 1, allowing the user to select and activate different groups of electrodes 5 and adjust the cleaning power.
[0014] When in use, fruits and vegetables to be cleaned are placed in a water tank. Electrodes 5 are energized in the water to generate hydroxyl radicals, which effectively degrade pesticide residues. The switch array 2 can adjust the number of electrode 5 working groups according to the amount of fruit and vegetables, achieving energy-saving cleaning.
[0015] Example 2, based on Example 1, in this example, see Figure 1The device for degrading pesticide residues in fruits and vegetables shown in the figure includes a cabinet 1, which is connected to several electrodes 5 via connecting wires 4. The cabinet 1 has a built-in high-efficiency, low-power power supply 3, which includes a pulse generator and a pulse power amplifier. The electrodes 5 are pollution-free lysis electrodes 5 placed in a water tank. The cabinet 1 is provided with a switch array 2 for controlling the on and off of the electrode 5 working group.
[0016] The input voltage of the high-efficiency, low-power power supply is 220 V. The electrodes 5 are made of inert materials and can be adsorbed or fixed in the treatment tank. The switch array 2 can selectively activate different electrode 5 working groups to achieve power adaptive regulation.
[0017] The cabinet 1 (including a high-efficiency, low-power power supply, a pulse generator, a pulse power amplifier, and a switch array 2) is placed at a suitable location in the fruit and vegetable washing sink. The pollution-free lysis electrode 5 is placed or adsorbed at a suitable location in the sink. The pollution-free lysis electrode 5 and the cabinet 1 are connected with pollution-free wires to complete the installation.
[0018] According to the amount of water in the sink, turn on the corresponding switch, observe with your eyes or use an instrument to test the relative concentration of hydroxyl radicals in the sink, and use a stopwatch to time the time for hydroxyl radicals (water catalyst) to cover the sink. Generally, it will be completely covered in 60 seconds. Put fruits and vegetables in, and the degradation of pesticide residues in fruits and vegetables will be completed in 30 minutes.
[0019] Testing pesticide residues in fruits and vegetables: Use a food safety tester to test the pesticide residues in fruits and vegetables before and after degradation to obtain the degradation effect of the pesticide residues.
[0020] The relative concentration of hydroxyl radicals is -300mv and the input voltage index is 220V. According to the different needs of removing pesticide residues from different fruits and vegetables, the number of working groups of the 5 pollution-free electrodes deployed in different locations can be adjusted to achieve optimal efficiency and power consumption.
[0021] The present invention has an adaptive working mode, and only one adjustment is required for one type of fruit or vegetable to complete the entire cleaning process. The present invention solves the problem of low-cost use for farmers. In other embodiments, an automatic billing system can be added. Farmers only need to renew the payment according to the time specified in the contract, and the system will work automatically.
