[0019] (2) In the present invention, by arranging a humidifying mechanism, although air cooling can dissipate heat from fruits and vegetables, it will also cause the evaporation of moisture on the surface of the fruits and vegetables, which may cause excessive water loss in the fruits and vegetables. The humidifying mechanism sprays water mist to increase the air humidity and reduce the water loss of the fruits and vegetables;

[0020] (3) In the present invention, by arranging a baffle, the baffle can block the atomizing nozzles. As more fruits and vegetables are added, more atomizing nozzles work, and the water spray volume can be adaptively adjusted according to the weight and volume of the fruits and vegetables, reducing the waste of water resources while ensuring the humidifying effect.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 3As shown in the figure, the present invention is a food processing device based on electromagnetic field-assisted ion penetration, including a processing box 1. Electrode plates 2 are fixed on the inner walls around the processing box 1. A placement and heat dissipation mechanism 3 is arranged in the processing box 1; the placement and heat dissipation mechanism 3 includes a placement plate 301. Air-cooling plates 302 are symmetrically arranged on the upper surface of the placement plate 301. The air-cooling plates 302 are of rectangular cavity structure, and ventilation holes are arranged in an array on the side walls of the two air-cooling plates 302 close to each other. An air inlet hose is connected to the air-cooling plates 302, and one end of the air inlet hose penetrates through the processing box 1 and is connected to an external cold air source. Rectangular holes are symmetrically opened on the top wall of the processing box 1. The rectangular holes match the sizes of the air-cooling plates 302. A sealing cover 303 is fixed at the rectangular holes. One end of the air-cooling plate 302 penetrates through the rectangular holes and extends into the sealing cover 303; a support mechanism is fixed at the bottom of the placement plate 301; exhaust ports 7 are symmetrically opened on the bottom wall of the processing box 1; it also includes a plurality of adjustable voltage stabilizers, and the plurality of electrode plates 2 are respectively electrically connected to the plurality of adjustable voltage stabilizers; a feeding port 5 is opened on the top wall of the processing box 1, and a sealing cover plate 6 is arranged at the feeding port 5; the fruits and vegetables to be processed are placed on the placement plate 301 through the feeding port 5. As the number of fruits and vegetables increases, the weight also increases, causing the placement plate 301 to descend accordingly. The descent of the placement plate 301 drives the air-cooling plates 302 to descend, exposing more ventilation holes in the processing box 1. After the fruits and vegetables are placed, the sealing cover plate 6 is covered. The adjustable voltage stabilizer delivers pulsed power to the electrode plates 2. The magnetic field frequency, magnetic field intensity, and electromagnetic processing time of the magnetic field generated by the electrode plates 2 can be adjusted through the adjustable voltage stabilizer, prompting ions to penetrate into the fruits and vegetables more quickly and evenly, improving the efficiency and effect of ion penetration. At the same time, cold air is conveyed into the air-cooling plates 302 through the air inlet hose, and the cold air blows towards the fruits and vegetables through the ventilation holes to dissipate heat from the fruits and vegetables. Finally, the air is discharged through the exhaust ports 7. According to the different weights of the fruits and vegetables, the exhaust volume is also different. When there are fewer fruits and vegetables, the exhaust volume also decreases, reducing energy consumption while ensuring the heat dissipation effect.

[0033] Refer to Figure 1 and Figure 2 , the support mechanism includes a plurality of support rods 304. The plurality of support rods 304 are all movably installed on the bottom wall of the processing box 1, and one ends of the plurality of support rods 304 are commonly fixed with a support plate 306, and the other ends are fixedly connected to the placement plate 301. Springs 305 are sleeved on the support rods 304, and the springs 305 are located between the placement plate 301 and the bottom wall of the processing box 1; the support rods 304 and the springs 305 are used in cooperation to support and fix the placement plate 301. After fruits and vegetables are placed on the placement plate 301, the springs 305 are compressed under the action of gravity, and the placement plate 301 automatically descends.

[0034] Refer to Figure 2 and Figure 4, humidifying mechanisms 4 are provided on both side walls of the treatment box 1. The humidifying mechanism 4 includes a liquid inlet pipe 401 fixed to the side wall of the treatment box 1 and multiple liquid distribution pipes 402. The multiple liquid distribution pipes 402 are connected by branch pipes 403. A plurality of atomizing nozzles 404 are uniformly arranged along the length direction on the side wall of the liquid distribution pipe 402 facing the placement plate 301. One end of the liquid inlet pipe 401 is connected to one of the liquid distribution pipes 402, and the other end is connected to an external water source; the humidifying mechanism 4 is used to spray water on fruits and vegetables to increase the air humidity and reduce the loss of water on the surface of fruits and vegetables.

[0035] Refer to Figure 1 and Figure 2 , baffles 307 are fixed on both sides of the placement plate 301, and the side walls of the baffles 307 are in contact with the atomizing nozzles 404; in order to reduce the waste of water resources, the baffles 307 block part of the atomizing nozzles 404 so that they cannot work normally by spraying water. Only the unblocked atomizing nozzles 404 at the top work. The more fruits and vegetables are placed, the greater the descending distance of the baffles 307 and the placement plate 301, and more atomizing nozzles 404 are no longer blocked. That is to say, the water spray volume also changes adaptively with the increase of fruits and vegetables.

[0036] Refer to Figure 1 and Figure 2 , first collection boxes 308 are fixed to the bottoms of the side walls of the two baffles 307 close to each other. The cross-sectional areas of the baffles 307 and the first collection boxes 308 are the same as the cross-sectional area of the exhaust port 7; the first collection boxes 308 can be used to collect the aqueous solution flowing down from the placement plate 301.

[0037] Refer to Figure 1 , Figures 5 to 7, a drain pipe 309 is connected to the bottom of the first collection box 308. Drain holes 310 are formed on both sides of the drain pipe 309. A blocking block 311 is arranged inside the drain pipe 309. A T-shaped hole 312 is formed on the blocking block 311. A limiting block 313 is further arranged at the bottom of the drain pipe 309. Second collection boxes 8 are symmetrically arranged at the bottom of the treatment box 1. A crossbar 9 is fixed on the second collection box 8. A pushing block 10 is fixed on the crossbar 9, and the pushing block 10 is located directly below the drain pipe 309; when the fruits and vegetables placed on the placing plate 301 reach the load limit, the baffle 307 and the first collection box 308 just enter the air outlet 7 to block the air outlet 7. At this time, all the atomizing nozzles 404 work, and the water spraying amount reaches the maximum. At the same time, the pushing block 10 enters the drain pipe 309 to lift the blocking block 311, so that the T-shaped hole 312 is aligned with the drain hole 310, and the collected aqueous solution flows into the second collection box 8 through the T-shaped hole 312 and the drain hole 310, avoiding the aqueous solution flowing around and affecting the working environment. And because the air outlet 7 is blocked at this time, air can only be discharged through the T-shaped hole 312 and the drain hole 310, reducing the discharge amount of cold air. When placing a large amount of vegetables, the contact time between the cold air and the vegetables can be prolonged, improving the heat dissipation effect.

[0038] The working principle of the present invention: In the initial state, under the action of the spring 305, the placing plate 301 is located at a position above the middle in the treatment box 1. The baffle 307 blocks some of the atomizing nozzles 404 on both sides, and the uppermost atomizing nozzle 404 is not blocked. And a part of the air-cooling plate 302 is also located inside the sealing cover 303, and only some of the ventilation holes can work normally. Place the vegetables to be processed on the placing plate 301 through the feeding port 5. After the placing plate 301 bears the gravity, it will squeeze the spring 305 and descend. The more fruits and vegetables are placed in a stacked manner, the greater the descending distance of the placing plate 301, enabling more ventilation holes and atomizing nozzles 404 to work. After the fruits and vegetables are placed, cover the sealing cover plate 6. The adjustable constant-voltage power supply sends a pulsed power supply to the electrode plate 2. The adjustable constant-voltage power supply can adjust the magnetic field frequency, magnetic field intensity, and electromagnetic treatment time of the magnetic field generated by the electrode plate 2, prompting ions to penetrate into the fruits and vegetables more quickly and evenly, improving the efficiency and effect of ion penetration;

[0039] Then use an external cold air source (not shown) and an air inlet hose (not shown) to send cold air to the air-cooling plate 302. The cold air blows evenly on the fruits and vegetables to dissipate heat from the fruits and vegetables. At the same time, an external water source (not shown) sends tap water to the liquid inlet pipe 401. The tap water passes through the liquid distribution pipe 402 and the branch pipe 403, and finally is sprayed on the fruits and vegetables through the atomizing nozzles 404 to increase the air humidity, which can reduce the loss of moisture on the surface of the fruits and vegetables and ensure the quality of the fruits and vegetables. Finally, the cold air is discharged through the air outlet 7, and the first collection box 308 can collect the excess tap water flowing down from the placing plate 301;

[0040] When the fruits and vegetables placed on the placement plate 301 reach the load limit, the baffle 307 and the first collection box 308 just enter the exhaust port 7 to block the exhaust port 7. At this time, all the atomizing nozzles 404 work, the water spraying amount reaches the maximum, and all the ventilation holes also work, the air output reaches the maximum. At the same time, the push block 10 enters the drain pipe 309 to lift the blocking block 311, so that the T-shaped hole 312 is aligned with the drain hole 310. The aqueous solution collected by the first collection box 308 flows into the second collection box 8 through the T-shaped hole 312 and the drain hole 310, avoiding the overflow of the aqueous solution into the treatment box 1. And because the exhaust port 7 is blocked at this time, the air can only be discharged through the T-shaped hole 312 and the drain hole 310, reducing the discharge amount of cold air, which can prolong the contact time between the cold air and the vegetables and improve the heat dissipation effect.

[0041] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the patent coverage scope of the present invention.
