The strong oxidizing property of ozone water can destroy the cell structure and function of microorganisms, and ozone is mainly converted into oxygen after decomposition in water. Therefore, no harmful residual substances will be left in the sterilization process, so a green and healthy sterilization effect is achieved, and the safety of shellfish and seafood consumption is improved.

[0039] Through the arrangement of the above structure, when the food tray 5 is completely immersed in the ozone water, the driving motor 7 is turned on, and the transmission of the pulley group 71 is coordinated to the left and right, so that the locking shaft 2 and the guide shaft 6 rotate synchronously. During the rotation of the locking shaft 2, the food tray 5 will be driven to rotate, so that the shellfish and seafood can be evenly contacted with the ozone water, which effectively improves the sterilization effect. Moreover, the friction effect of the water flow resistance generated during the rotation can also be used to wash away the impurities such as mud and sand remaining on the surface of the shellfish and seafood, thereby improving the neatness of the shellfish and seafood, making its appearance look cleaner and more hygienic, and facilitating subsequent sales; and when the guide shaft 6 drives the guide impeller 61 to rotate, the guide blades 642 in the guide box 641 will be driven to rotate, thereby generating a negative pressure adsorption effect in the guide shaft 6, and when cooperating with the guide shaft 6, the water resistance plate 63 is subjected to the resistance of the ozone water, so that the water resistance plate 63 retracts in the guide groove 62, thereby connecting the guide groove 62 with the collecting cylinder 4. At this time A directional water flow effect will be generated (entering the collection tube 4 from the sterilization tank 1, and entering the guide shaft 6 along the guide groove 62, and then passing through the guide box 641 and the guide tube 64 to enter the water column disk 65, and then returning to the sterilization tank 1 again), and in the process of the ozone water flow entering the guide shaft 6 from the guide groove 62, it will be filtered by the fine mesh filter 621, so that the mud and sand impurities contained in the ozone water flow and the sediment produced by the decomposed bacteria are filtered and collected in the guide groove 62, and when the guide shaft 6 stops rotating, under the rebound action of the first spring 631, the water resistance plate 63 will reset to block the input port of the guide groove 62, so as to isolate the collected materials, ensure the cleanliness of the ozone water, and improve the sterilization and cleaning effect; and after the ozone water enters the water column disk 65, it will be sprayed upward along the multiple groups of water column grooves 651, so as to generate multiple groups of flowing water columns in the sterilization tank 1, so as to achieve the flushing of shellfish and seafood, and further improve the sterilization and cleaning effect.

[0040] Reference Figure 1 , Figure 2 and Figure 6 An auxiliary punching groove 52 is provided on the side wall of the food plate 5 between two adjacent groups of containing grooves 51, and multiple groups of auxiliary punching holes 521 are provided on both sides of the inner cavity of the auxiliary punching groove 52. A first magnetic block 522 is slidably connected in the auxiliary punching groove 52, and a second magnetic block 611 is fixedly connected to the side wall of the guide impeller 61, and the second magnetic block 611 and the first magnetic block 522 repel each other magnetically.

[0041] By setting the above structure, when the guide impeller 61 rotates, the repulsive effect of the first magnetic block 522 and the second magnetic block 611 will cause the first magnetic block 522 to slide into the auxiliary flushing groove 52, thereby compressing the ozone water in the auxiliary flushing groove 52, so that the ozone water is sprayed into the containing groove 51 along the multiple groups of auxiliary flushing holes 521, thereby generating a water flushing effect in the containing groove 51, thereby improving the sterilization and flushing effect. Subsequently, when the first magnetic block 522 and the second magnetic block 611 are separated from the magnetic area, under the action of the centrifugal force of the rotation of the food plate 5, the first magnetic block 522 will move to the edge of the auxiliary flushing groove 52 again, so as to squeeze the ozone water again, thereby achieving a continuous flushing effect, and further improving the sterilization and flushing effect.

[0042] Reference Figure 3 , Figure 6-Figure 8 Among them, a parking plate 8 is fixedly connected to the bottom outer wall of the locking shaft 2, three groups of lifting grooves 81 are evenly spaced on the top of the parking plate 8, an air pressure groove 82 is opened in the parking plate 8, the air pressure groove 82 is connected to the lifting groove 81, a lifting column 81 is slidably connected in the lifting groove 81, a second spring 812 is fixedly connected between the bottom end of the lifting column 81 and the air pressure groove 82, a piston box 83 is fixedly connected to the bottom of the inner cavity of the sterilization tank 1, a magnetic slide 831 is slidably connected in the piston box 83, a third spring 832 is fixedly connected between the side wall of the magnetic slide 831 and the piston box 83, and the magnetic slide 831 and the second magnetic block 611 repel each other, and an air guide tube 833 is fixed and connected to the side wall of the piston box 83, and the other end of the air guide tube 833 is connected to the inner cavity of the air pressure groove 82.

[0043] It should be noted that the gas pressure generated by the repulsive force between the three groups of magnetic slides 831 and the second magnetic block 611 combined with the buoyancy of the ozone water in the sterilization tank 1 is greater than the overall gravity of the three groups of food plates 5 .

[0044] By setting the above structure, when the guide impeller 61 rotates, the repulsive effect of the second magnetic block 611 and the magnetic slide 831 will cause the magnetic slide 831 to retract into the piston box 83, thereby compressing the gas in the piston box 83, so that the gas in the three groups of piston boxes 83 are all pressed into the air pressure groove 82, so that the lifting column 811 has a tendency to move upward. At this time, the buoyancy of the ozone water will lift the food plate 5 upward, and then the second magnetic block 611 and the magnetic slide 831 will be separated from the repulsive area, and the food plate 5 will sink under the action of gravity, and the food plate 5 will reciprocate up and down for a short distance. In the process of moving, the flushing effect of the ozone water on shellfish and seafood can be improved, and the sterilization and flushing effect is further improved.

[0045] Reference Figure 6 , Figure 7, wherein the inflation part includes three groups of inflation boxes 9, and the three groups of inflation boxes 9 are evenly spaced at the bottom of the sterilization tank 1. A protruding slider 91 is slidably connected in the inflation box 9, and a fourth spring 92 is fixedly connected between the side wall of the protruding slider 91 and the inflation box 9. A cam block 93 is fixedly connected to the side wall of the runner located on the outer wall of the guide shaft 6 in the pulley group 71, and the cam block 93 is in active contact with the protruding slider 91. One end of the inflation box 9 close to the guide pipe 64 is fixed and connected with an inflation pipe 94, and the other end of the inflation pipe 94 is connected to the inner cavity of the guide pipe 64, and a one-way valve is arranged in the inflation pipe 94; an air suction pipe 95 is fixed and connected to the side wall of the inflation box 9, and the input end of the air suction pipe 95 extends to the top of the sterilization tank 1, and the input end of the air suction pipe 95 faces the center of the sterilization tank 1, and a one-way valve is arranged in the air suction pipe 95.

[0046] It should be noted that the one-way valve in the inflation tube 94 can only allow the gas in the inflation box 9 to enter the guide tube 64; the one-way valve in the suction tube 95 can only allow the airflow in the top area of ​​the sterilization tank 1 to enter the inflation box 9.

[0047] Through the arrangement of the above structure, during the rotation of the pulley group 71, the cam block 93 will intermittently contact the protruding slider 91, and during the contact process, the cam block 93 will push the protruding slider 91 into the inflation box 9, thereby compressing the gas in the inflation box 9 and opening the one-way valve in the inflation pipe 94, so that the gas enters the ozone water along the inflation pipe 94 and the guide pipe 64, and after passing through the multiple groups of water column grooves 651, a large number of bubbles will be generated at the bottom of the ozone water. When the bubbles float up and hit the shellfish and seafood, some of the bubbles will burst, thereby generating rupture tension on the surface of the shellfish and seafood, thereby effectively Impurities, bacteria, etc. attached to the surface of shellfish and seafood are removed, which effectively improves the sterilization and cleaning effect. Subsequently, when the cam block 93 is out of contact with the protruding slider 91, the protruding slider 91 will slide back under the rebound action of the fourth spring 92, thereby generating suction in the inflation box 9 and opening the one-way valve in the suction pipe 95, so that the oxygen overflowing from the top of the sterilization tank 1 (generated during the decomposition of ozone sterilization) is captured and sucked into the inflation box 9, so that the oxygen content of the airflow subsequently filled with ozone water is increased, thereby slowing down the decomposition rate of ozone and extending its effective sterilization time in water, thereby improving the sterilization effect.

[0048] Reference Figure 1-Figure 8In the present invention, when in use, first put the shellfish into the containing groove 51 of the food plate 5, then hook the pull ring 31 by the existing lifting device, align the locking sleeve 3 with the locking shaft 2 and insert it, and then immerse the multiple groups of food plates 5 into the ozone water in the sterilization tank 1 along the locking shaft 2. The strong oxidizing property of the ozone water can destroy the cell structure and function of the microorganisms, and the ozone is mainly converted into oxygen after decomposition in the water. Therefore, no harmful residual substances will be left in the sterilization process, achieving a green and healthy sterilization effect, and improving the safety of shellfish.

[0049] When the food tray 5 is completely immersed in the ozone water, the driving motor 7 is turned on, and the transmission of the pulley group 71 is coordinated to the left and right, so that the locking shaft 2 and the guide shaft 6 rotate synchronously. During the rotation of the locking shaft 2, the food tray 5 will be driven to rotate, so that the shellfish and seafood can be evenly contacted with the ozone water, which effectively improves the sterilization effect. In addition, the friction effect of the water flow resistance generated during the rotation can also be used to wash away the impurities such as mud and sand remaining on the surface of the shellfish and seafood, thereby improving the neatness of the shellfish and seafood, making its appearance look cleaner and more hygienic, and facilitating subsequent sales. When the guide shaft 6 drives the guide impeller 61 to rotate, the guide blades 642 in the guide box 641 will be driven to rotate, thereby generating a negative pressure adsorption effect in the guide shaft 6, and when cooperating with the guide shaft 6, the water resistance plate 63 is subjected to the resistance of the ozone water, so that the water resistance plate 63 moves to The guide groove 62 retracts to connect the guide groove 62 and the collecting tube 4, and a directional water flow will be generated at this time. In the process of the ozone water flow entering the guide shaft 6 from the guide groove 62, it will be filtered by the fine-mesh filter 621, so that the mud and sand impurities contained in the ozone water flow and the sediment produced by the decomposed bacteria are filtered and collected in the guide groove 62, and when the guide shaft 6 stops rotating, under the rebound action of the first spring 631, the water resistance plate 63 will reset to block the input port of the guide groove 62, so as to isolate the collected materials, ensure the cleanliness of the ozone water, and improve the sterilization and cleaning effect; and after the ozone water enters the water column plate 65, it will be sprayed upward along the multiple groups of water column grooves 651, so as to generate multiple groups of flowing water columns in the sterilization tank 1, so as to flush the shellfish and seafood, and further improve the sterilization and cleaning effect.

[0050] When the guide impeller 61 rotates, the repulsive effect of the first magnetic block 522 and the second magnetic block 611 will cause the first magnetic block 522 to slide into the auxiliary flushing groove 52, thereby compressing the ozone water in the auxiliary flushing groove 52, so that the ozone water is sprayed into the containing groove 51 along the multiple groups of auxiliary flushing holes 521, thereby generating a water flushing effect in the containing groove 51, thereby improving the sterilization and flushing effect. Subsequently, when the first magnetic block 522 and the second magnetic block 611 are separated from the magnetic area, under the action of the centrifugal force of the rotation of the food plate 5, the first magnetic block 522 will move to the edge of the auxiliary flushing groove 52 again, so as to squeeze the ozone water again, thereby achieving a continuous flushing effect, and further improving the sterilization and flushing effect. In addition, with the repulsive effect of the second magnetic block 611 and the magnetic slide 831, the magnetic slide 831 will retract into the piston box 83, thereby compressing the gas in the piston box 83, so that the gas in the three groups of piston boxes 83 is pressed into the air pressure groove 82, so that the lifting column 811 has a tendency to move upward. At this time, with the buoyancy of the ozone water, the food plate 5 will be lifted up, and then the second magnetic block 611 and the magnetic slide 831 will be separated from the repulsive area, and the food plate 5 will sink under the action of gravity. In this way, the food plate 5 will reciprocate up and down for a short distance. During the movement, the flushing effect of the ozone water on shellfish and seafood can be improved, further improving the sterilization and flushing effect.

[0051] During the rotation of the pulley assembly 71, the cam block 93 will intermittently contact the protruding slider 91, and during the contact process, the cam block 93 will push the protruding slider 91 into the inflation box 9, thereby compressing the gas in the inflation box 9 and opening the one-way valve in the inflation pipe 94, so that the gas enters the ozone water along the inflation pipe 94 and the guide pipe 64, and after passing through the multiple groups of water column grooves 651, a large number of bubbles will be generated at the bottom of the ozone water. When the bubbles float up and hit the shellfish and seafood, some of the bubbles will burst, thereby generating rupture tension on the surface of the shellfish and seafood, thereby effectively Impurities, bacteria, etc. attached to the surface of shellfish and seafood are removed, effectively improving the sterilization and cleaning effect. Subsequently, when the cam block 93 is out of contact with the protruding slider 91, the protruding slider 91 will return to its original position under the rebound action of the fourth spring 92, thereby generating suction in the inflation box 9 and opening the one-way valve in the suction pipe 95, so that the oxygen overflowing from the top of the sterilization tank 1 is captured and sucked into the inflation box 9, thereby increasing the oxygen content of the airflow subsequently filled with ozone water, thereby slowing down the decomposition rate of ozone and extending its effective sterilization time in water, thereby improving the sterilization effect.

[0054] Step 1, after putting shellfish and seafood into the food tray 5, immerse it in the ozone water in the sterilization tank 1: put the shellfish and seafood into the holding groove 51 of the food tray 5, then hook the pull ring 31 with the existing lifting device, align the locking sleeve 3 with the locking shaft 2 and insert it, then immerse multiple groups of food trays 5 along the locking shaft 2 into the ozone water in the sterilization tank 1. The strong oxidizing property of ozone water can destroy the cell structure and function of microorganisms, and ozone is mainly converted into oxygen after decomposition in water. Therefore, no harmful residual substances will be left in the sterilization process, so a green and healthy sterilization effect is achieved, and the safety of shellfish and seafood consumption is improved.

[0055] Step 2: Rotate and rinse the seafood in the food tray 5 to sterilize it, and filter and collect the impurities in the ozone water in real time: turn on the drive motor 7, cooperate with the transmission of the pulley group 71, so that the locking shaft 2 and the guide shaft 6 rotate synchronously. During the rotation of the locking shaft 2, the food tray 5 will be driven to rotate, so that the shellfish and seafood can be evenly contacted with the ozone water, which effectively improves the sterilization effect. In addition, the friction effect of the water flow resistance generated during the rotation can also be used to rinse the impurities such as mud and sand remaining on the surface of the shellfish and seafood, thereby improving the neatness of the shellfish and seafood, making its appearance look cleaner and more hygienic, and facilitating subsequent sales. When the guide shaft 6 drives the guide impeller 61 to rotate, it will drive the guide blades 642 in the guide box 641 to rotate. When the guide shaft 6 is rotated, a negative pressure adsorption effect is generated in the guide shaft 6, and when the guide shaft 6 is cooperated, the water resistance plate 63 is affected by the ozone water resistance, so that the water resistance plate 63 retracts into the guide groove 62, thereby connecting the guide groove 62 and the collecting cylinder 4. At this time, a directional water flow effect will be generated, and in the process of the ozone water flow entering the guide shaft 6 from the guide groove 62, it will be filtered by the fine mesh filter 621, so that the mud and sand impurities contained in the ozone water flow and the sediment produced by the decomposed bacteria are filtered and collected in the guide groove 62, and when the guide shaft 6 stops rotating, under the rebound effect of the first spring 631, the water resistance plate 63 will reset to block the input port of the guide groove 62, so as to achieve isolation of the collected objects, ensure the cleanliness of the ozone water, and improve the sterilization and cleaning effect.

[0056] Step 3: Fill the ozone water with gas to form a large number of bubbles, and use the tension of the bubble bursting to clean the surface of the seafood: during the rotation of the pulley group 71, the cam block 93 will intermittently contact the protruding slider 91, and during the contact process, the cam block 93 will push the protruding slider 91 into the inflation box 9, thereby compressing the gas in the inflation box 9 and opening the one-way valve in the inflation pipe 94, so that the gas enters the ozone water along the inflation pipe 94 and the guide pipe 64, and after passing through multiple groups of water column grooves 651, a large number of bubbles will be generated at the bottom of the ozone water. When the bubbles float up and hit the shellfish, some of the bubbles will burst. , thereby generating rupture tension on the surface of shellfish and seafood, thereby effectively removing impurities, bacteria, etc. attached to the surface of shellfish and seafood, effectively improving the sterilization and cleaning effect. Subsequently, when the cam block 93 is out of contact with the protruding slider 91, under the rebound action of the fourth spring 92, the protruding slider 91 will return to its original position and slide, thereby generating suction in the inflation box 9 and opening the one-way valve in the suction pipe 95, so that the oxygen overflowing from the top of the sterilization tank 1 is captured and sucked into the inflation box 9, so that the oxygen content of the airflow subsequently filled with ozone water is increased, thereby slowing down the decomposition rate of ozone and extending its effective sterilization time in water, thereby improving the sterilization effect.
