[0020] like Figures 1 to 3As shown, this embodiment of the utility model provides a plasma sterilization treatment device, including a frame 100 and a body 200.

[0021] The frame 100 is placed vertically, and the main body 200 is set inside the frame 100. The main body 200 has a processing cavity 240 extending through its upper and lower ends. A high-voltage electrode plate 300 is set at the upper end of the processing cavity 240, and a grounding electrode plate 400 is set at the lower end. The high-voltage electrode plate 300 and the grounding electrode plate 400 respectively seal the upper and lower ends of the processing cavity 240. An electrode rod 310 is vertically arranged on the high-voltage electrode plate 300, and the lower end of the electrode rod 310 extends into the processing cavity 240. Multiple electrode rods 310 are evenly distributed, preferably seventeen in this embodiment. The side wall of the main body 200 is also provided with a feed inlet 212 and a discharge outlet 231, with the feed inlet 212 being higher than the discharge outlet 231. The frame 100 is provided with an N-pole magnet 110 located above the high-voltage electrode plate 300 and a P-pole magnet 120 located below the ground electrode plate 400. The frame 100 is also provided with coils 130 located on both sides of the body 200, and the coils 130 are wound in the vertical direction.

[0022] During operation, liquid food enters the processing chamber 240 through the feed inlet 212. The high-voltage electrode plate 300 generates plasma through high-voltage discharge, which disinfects and sterilizes the liquid food flowing into the processing chamber 240 from the feed inlet 212. The grounding electrode plate 400, together with the high-voltage electrode plate 300, forms an electric field circuit to ensure the smooth progress of the disinfection and sterilization process. The N-pole magnet 110 and the P-pole magnet 120 form an electromagnetic field, and the intensity of the electromagnetic field is controlled by the coil 130. The stronger the magnetic field, the more pulses, which can effectively improve the efficiency of killing harmful microorganisms in the liquid food.

[0023] In one embodiment, two mounting plates 500 are arranged vertically spaced within the processing cavity 240. The two mounting plates 500 are located between the high-voltage electrode plate 300 and the grounding electrode plate 400, so that the processing cavity 240 forms a first cavity 241, a cooling cavity 242, and a second cavity 243 arranged sequentially from top to bottom. The feed inlet 212 is connected to the first cavity 241, and the discharge outlet 231 is connected to the second cavity 243. A vertically arranged guide pipe 600 is installed inside the cooling chamber 242. The upper and lower ends of the guide pipe 600 pass through two mounting plates 500 respectively. The side wall of the main body 200 is provided with an inlet 221 and an outlet 222 that communicate with the cooling chamber 242. The cooling chamber 242 is designed to cool down the liquid food in the first cavity 241, the guide pipe 600, and the second cavity 243 to prevent the liquid food from being damaged by heat, which could cause changes in taste or nutritional components and affect the quality of the liquid food. Specifically, cold water enters the cold water chamber through the inlet 221 to absorb the temperature of the liquid food in the first cavity 241, the guide pipe 600, and the second cavity 243, and is then discharged from the outlet 222. Specifically, the inlet 221 is higher than the outlet 222. More specifically, the inlet 221 is located near the upper end of the second annular wall 220, and the outlet 222 is located near the lower end of the second annular wall 220, thereby improving the efficiency of water intake and output and thus improving the cooling efficiency.

[0024] In one embodiment, multiple guide tubes 600 are evenly distributed and gaps are formed between the guide tubes 600, thereby improving heat exchange efficiency and material guiding efficiency, thus improving work efficiency.

[0025] In one embodiment, the body 200 includes a first annular wall 210, a second annular wall 220, and a third annular wall 230 arranged sequentially from top to bottom. The first annular wall 210, the second annular wall 220, and the third annular wall 230 form a processing cavity 240. Further, two mounting plates 500 are welded to the upper and lower ends of the second annular wall 220 to form a cooling cavity 242. Further, the first annular wall 210 is welded to the upper end of the upper mounting plate 500, and a high-voltage electrode plate 300 is mounted on the upper end of the first annular wall 210 to form a first cavity 241. The third annular wall 230 is welded to the lower end of the lower mounting plate 500, and a grounding electrode plate 400 is mounted on the lower end of the third annular wall 230 to form a second cavity 243. Furthermore, the feed inlet 212 is located on the side wall of the first annular wall 210, the discharge outlet 231 is located on the side wall of the third annular wall 230, and the water inlet 221 and the water outlet 222 are located on the second annular wall 220. The overall structure is simple and facilitates the processing and assembly of the treatment device.

[0026] In one embodiment, the upper edge of the first annular wall 210 extends outward horizontally to form a brim 211, and an annular insulating pad 700 is provided at the upper end of the brim 211. The high-voltage electrode 300 abuts against the annular insulating pad 700 to avoid the high-voltage electrode 300 being affected by the body 200.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
