Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable processing technology, specifically to an enzyme inactivation device for fruit and vegetable processing with automatic feeding capability. Background Technology

[0002] In the fruit and vegetable processing industry, enzyme inactivation is crucial. Fruits and vegetables contain various enzymes, such as polyphenol oxidase and peroxidase, which can cause numerous problems if not effectively treated during processing. Enzymatic browning causes fruit and vegetable products to darken in color, significantly affecting their appearance and reducing consumer purchasing desire. Simultaneously, enzyme activity can alter the flavor and nutritional components of fruits and vegetables, leading to a decline in product quality and a shortened shelf life. Therefore, efficient and precise enzyme inactivation is key to ensuring the quality of processed fruit and vegetable products. Various enzyme inactivation methods exist, among which ozone inactivation is a relatively new approach. Its principle primarily utilizes the strong oxidizing properties of ozone, soaking fruits and vegetables in ozone water to achieve enzyme inactivation. This process requires the use of an enzyme inactivation device.

[0003] However, existing enzyme inactivation devices for fruit and vegetable processing still have certain shortcomings in use;

[0004] As proposed in application CN202021489806.9, a preheating enzyme inactivation machine for fruit and vegetable processing includes a chamber. An installation chamber is located at the middle of one side of the chamber. A servo motor is located inside the installation chamber on the side away from the chamber. A first rotating rod is located at the output end of the servo motor and extends into the interior of the chamber. An inner barrel is fitted at the middle of the outer side of the first rotating rod. An infrared heating roller is located inside the inner barrel. An outer barrel is fitted outside the first rotating rod, and the outer barrel is fitted outside the inner barrel. A storage chamber is located at the middle of the top of the chamber. An air pipe is located at the bottom of the storage chamber on the side away from the servo motor. This device, through the cooperation of the inner barrel, the first rotating rod, the infrared heating roller, and the servo motor, can drive the enzyme inactivation chamber to rotate during the enzyme inactivation process, ensuring that the fruits and vegetables inside the chamber are fully inactivated, thereby improving the enzyme inactivation effect of the device. However, in actual use, the following problems still exist:

[0005] 1. This preheating enzyme inactivation machine for fruit and vegetable processing uses high temperature to inactivate enzymes in fruits and vegetables, which will cause a large loss of heat-sensitive nutrients in fruits and vegetables, such as vitamin C and B vitamins, and will not be able to better maintain the nutritional value of fruits and vegetables.

[0006] 2. Existing enzyme inactivation devices for fruit and vegetable processing have many shortcomings in terms of automatic feeding. Some devices rely on manual feeding, which is not only labor-intensive and inefficient, but also prone to uneven feeding due to differences in manual operation, thus affecting the consistency of enzyme inactivation effect. In addition, material accumulation after feeding can also affect the enzyme inactivation effect.

[0007] 3. Existing devices have significant shortcomings in terms of sufficient contact with fruits and vegetables. Some devices use a simple spraying method, where ozone water can only act on the surface of fruits and vegetables. For fruits and vegetables with complex structures, gaps, or holes, such as broccoli and strawberries, it is difficult for the interior to come into contact with a sufficient concentration of ozone water, resulting in incomplete enzyme inactivation and affecting product quality. Although some devices use an immersion type, they lack an effective stirring or circulation mechanism, resulting in uneven contact between ozone water and fruits and vegetables, which affects the enzyme inactivation effect.

[0008] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0009] To address the aforementioned issues, an innovative design was developed based on the existing enzyme inactivation device for fruit and vegetable processing that can automatically feed ingredients. Summary of the Invention

[0010] The purpose of this invention is to provide an enzyme inactivation device for fruit and vegetable processing with automatic feeding capability, in order to solve the problems mentioned in the background art, such as the loss of heat-sensitive nutrients due to high-temperature enzyme inactivation, the high labor intensity and low efficiency of manual feeding, the uneven feeding and easy accumulation affecting the consistency of enzyme inactivation, the difficulty of spraying to act on the complex interior of fruits and vegetables leading to incomplete enzyme inactivation, and the uneven contact of ozone water due to the lack of effective stirring or circulation in the soaking method.

[0011] To achieve the above objectives, the present invention provides the following technical solution: an enzyme inactivation device for fruit and vegetable processing with automatic feeding capability, comprising a processing box, a cover plate fixedly installed on the top of the processing box, and a feeding control mechanism provided at the front end of the processing box;

[0012] The processing box is equipped with equally spaced rotating transmission rods inside. The outer ring of the transmission rods is fitted with a hollowed-out conveyor belt. The left end of the top transmission rod is connected to a second servo motor, which is fixedly connected to the left side of the processing box.

[0013] A piston aeration mechanism is provided on the front left side of the treatment box. A drive motor is connected to the top of the piston aeration mechanism. The drive motor is fixedly connected to the left side of the treatment box.

[0014] The piston aeration mechanism is connected to a linkage circulation mechanism on both sides of its top.

[0015] A discharge box is fixedly connected to the bottom rear end of the cover plate;

[0016] A partition plate is fixedly installed inside the processing box, and the rear side of the partition plate divides the processing box into an immersion chamber. A hollowed-out tray is movably placed inside the immersion chamber.

[0017] Preferably, the feeding control mechanism includes a feeding conveyor belt fixedly installed at the top front end of the processing box, and a servo motor is connected to the rear left end of the feeding conveyor belt. The servo motor is fixedly connected to the left side of the processing box.

[0018] Preferably, the control feeding mechanism further includes a movable sealing plate slidably disposed on the bottom front end of the cover plate. An electric telescopic rod is fixedly installed on the top front end of the cover plate. The front end of the electric telescopic rod is fixedly connected to the top front end of the movable sealing plate. Limiting rods are symmetrically installed on the top front end of the movable sealing plate. Positioning seats are symmetrically installed on the top front end of the cover plate. The limiting rods and positioning seats are slidably connected through the cover plate. A support frame is fixedly installed on the top front end of the processing box. A photoelectric sensor is installed in the middle front end of the support frame. A control processor is installed in the middle rear end of the support frame. The control processor, photoelectric sensor, and servo motor are electrically connected together.

[0019] By adopting the above technical solution, the feeding conveyor belt is driven by a servo motor, and the fruits and vegetables are dispersed on the feeding conveyor belt in conjunction with a vibrating plate, thus realizing automatic feeding of fruits and vegetables, replacing manual feeding, effectively reducing labor intensity, avoiding accumulation, and improving feeding efficiency, which provides a guarantee for the continuous operation of the subsequent enzyme inactivation process.

[0020] The photoelectric sensor can detect the amount of fruits and vegetables on the feeding conveyor belt and transmit the signal to the control processor. The control processor can control the speed of the servo motor and the electric telescopic rod according to the detection results, thereby controlling the opening and closing of the movable sealing plate and the start and stop of feeding, realizing the control of the feeding amount, avoiding uneven feeding and material accumulation, and ensuring the enzyme inactivation effect. At the same time, the closing of the movable sealing plate can also seal the top of the processing box, reducing the volatilization and emission of ozone water.

[0021] Preferably, the transmission rods are distributed at equal intervals at an oblique angle inside the processing box, and baffles are installed at equal intervals on the surface of the perforated conveyor belt.

[0022] Using the above technical solution, the obliquely distributed transmission rods make the perforated conveyor belt tilted. Combined with the baffles on the surface, this not only drives the fruits and vegetables to move stably in the processing box, but also prevents them from slipping during the movement. At the same time, the perforated structure does not affect the contact between ozone water and fruits and vegetables, ensuring that the fruits and vegetables can fully receive enzyme inactivation treatment during the transportation process.

[0023] Preferably, the piston aeration mechanism includes a sealed box fixedly installed on the left side of the treatment box. A reciprocating lifting plate is slidably arranged inside the sealed box. A reciprocating screw passes through the middle of the reciprocating lifting plate. The upper and lower ends of the reciprocating screw are rotatably connected to the sealed box.

[0024] Preferably, the piston aeration mechanism further includes air inlet valves symmetrically installed at the upper and lower ends of the left side of the sealed box, and air outlet valves symmetrically installed at the upper and lower ends of the right side of the sealed box. The air outlet end of the air outlet valve is fixedly connected to a connecting pipe, and the air outlet end of the connecting pipe is connected to a collecting pipe. The collecting pipe is fixedly connected through the left side of the treatment box. Diverting pipes are installed at equal intervals on the collecting pipe located inside the treatment box, and aeration discs are installed at equal intervals on the top of the diverting pipes.

[0025] Using the above technical solution, the drive motor drives the reciprocating screw to rotate, causing the reciprocating lifting plate to move up and down in the sealed box. With the unidirectional conduction of the air inlet valve and the air outlet valve, outside air is drawn in and compressed, and then transported to the aeration plate through the connecting pipe, the collecting pipe and the dividing pipe. The aeration plate releases a large number of bubbles, which causes the ozone water to turbulent in the treatment box, enhancing the contact between the ozone water and the fruits and vegetables. In particular, it allows the ozone water to penetrate into the interior and crevices of fruits and vegetables with complex structures, solving the problem of incomplete enzyme inactivation.

[0026] Preferably, the linkage circulation mechanism includes a drive gear fixedly sleeved on the outer ring of the top of the reciprocating lead screw, driven gears meshing parallel to each other on both sides of the drive gear, a rotating seat fixedly connected to the inner ring of the driven gear, conveying fan blades symmetrically distributed inside the rotating seat, and a positioning tube rotatably connected to the outer ring of the rotating seat. The positioning tube is a split type, and the upper and lower parts of the positioning tube are fixedly connected by a connecting seat.

[0027] Preferably, the linkage circulation mechanism further includes circulation pipes fixedly installed at the upper and lower ends of the positioning pipe. The circulation pipes at the upper and lower ends are connected through the processing box, and the circulation pipes at the upper and lower ends are fastened to the processing box through flanges. An output pipe is fixedly connected to the right end of the upper circulation pipe, and nozzles are installed at equal intervals at the bottom of the output pipe.

[0028] Using the above technical solution, when the reciprocating screw rotates, it drives the drive gear to rotate. Through gear meshing, it drives the driven gear and the rotating seat to rotate, causing the conveying fan blades to run. The ozone water at the bottom of the treatment box is transported to the output pipe through the circulation pipe, and then sprayed to the upper part of the treatment box through the nozzle, forming an ozone water circulation. This can effectively soak and spray fruits and vegetables to inactivate enzymes, improve the enzyme inactivation effect, and at the same time improve the utilization rate of ozone water.

[0029] Preferably, the discharge box is equipped with an upper guide plate and a lower guide plate installed at an angle inside, which can guide the discharge of fruits and vegetables.

[0030] By adopting the above technical solution, the oblique setting of the upper and lower guide plates can guide the enzyme-inactivated fruits and vegetables to be discharged smoothly and orderly from the processing box, reducing the damage to the fruits and vegetables due to collision during the discharge process and ensuring product quality.

[0031] Preferably, limit posts are installed at equal intervals at the bottom of both ends of the hollow basket, and a limit plate is fitted around the outer ring of the limit post. The inner side of the limit plate is fixedly connected to the outer facade of the processing box. The limit post and the limit plate are slidably connected. A telescopic spring is fitted around the outer ring of the limit post. The top of the telescopic spring is fixedly connected to the bottom surfaces of both ends of the hollow basket. A positioning nut is threaded onto the bottom surface of the middle limit post.

[0032] Using the above technical solution, the hollow tray can hold fruits and vegetables that need to be soaked. The cooperation between the limiting post and the limiting plate plays a limiting role in the hollow tray. The telescopic spring can buffer the impact force when fruits and vegetables are put in, avoiding damage to the fruits and vegetables. At the same time, the height of the hollow tray can be adjusted and limited by adjusting the positioning nut. The hollow structure ensures that the natural polyphenol fruit and vegetable coating agent can fully contact the soaking of fruits and vegetables, effectively improving the preservation effect of fruits and vegetables.

[0033] Preferably, guide rails are symmetrically installed on the rear inner wall of the processing box, a float plate is slidably installed inside the guide rail, and a striking rod is fixedly installed on the top surface of the float plate, the top of the striking rod being a spherical structure.

[0034] By employing the above technical solution, the upward thrust generated by the aeration disc pushing the ozone water upwards drives the float and the striking rod to rise. Then, the rotation of the perforated conveyor belt and baffle intermittently squeezes the striking rod, allowing the float to reciprocate within the guide rail. This reciprocates the striking rod, intermittently striking the perforated conveyor belt. This striking generates vibration in the perforated conveyor belt, causing slight vibration in the transported fruits and vegetables, ensuring sufficient contact between the fruits and vegetables and the ozone water. Furthermore, when the fruits and vegetables reach the top of the perforated conveyor belt, the vibration also assists in draining the water.

[0035] Preferably, the upper and lower guide plates have filter holes arranged in a rectangular array inside, electric heating wires are embedded in the upper and lower guide plates at equal intervals inside, water-absorbing cloth is connected to the top surface of the upper and lower guide plates, and a drain seat is installed at the bottom of the discharge box.

[0036] By adopting the above technical solution, the absorbent cloth on the surface of the upper and lower guide plates can absorb a certain amount of residual ozone water on the surface of the fruits and vegetables during the process of guiding them, ensuring the soaking effect of the fruits and vegetables with the natural polyphenol fruit and vegetable coating agent. The electric heating wire can effectively dry the absorbent cloth after water absorption. The filter hole design allows the ozone water to pass through the filter hole and be stored at the bottom of the discharge box when there is a lot of ozone water, and then discharged through the drain seat. At this time, the drain seat can be connected to the front part of the processing box to facilitate the recycling of the discharged ozone water and avoid resource waste.

[0037] Compared with existing technologies, the beneficial effects of this invention are as follows: This automatically feeding enzyme-inactivating device for fruit and vegetable processing, through its ingenious structural design and the synergistic cooperation between various mechanisms, comprehensively optimizes the enzyme-inactivating process of fruits and vegetables. It abandons the traditional high-temperature enzyme-inactivation method, using ozone water for enzyme inactivation treatment, fundamentally avoiding the loss of heat-sensitive nutrients, maximizing the preservation of the nutritional value of fruits and vegetables, and effectively solving problems such as nutrient loss during high-temperature enzyme inactivation, drawbacks of manual feeding, incomplete enzyme inactivation, and uneven contact of ozone water through the synergistic action of multiple mechanisms. Overall, it improves the efficiency and quality of fruit and vegetable enzyme-inactivating processing. Specific details are as follows:

[0038] 1. Regarding the control of the feeding mechanism, a servo motor drives the feeding conveyor belt to operate, which, together with the vibrating plate, realizes automatic feeding of fruits and vegetables, replacing manual labor, reducing labor intensity, avoiding accumulation, improving feeding efficiency, and ensuring the continuous operation of the subsequent enzyme inactivation process; a photoelectric sensor detects the amount of fruits and vegetables and transmits a signal to the control processor, which adjusts the speed of the servo motor and the electric telescopic rod accordingly, controls the opening and closing of the movable sealing plate and the start and stop of feeding, realizes the control of the feeding amount, avoids uneven feeding and accumulation, ensures the enzyme inactivation effect, and the closing of the movable sealing plate can also reduce the emission of volatile gases;

[0039] 2. In the piston aeration mechanism, the drive motor drives the reciprocating screw to rotate, causing the reciprocating lifting plate to move up and down in the sealed box. Combined with the one-way air inlet valve and outlet valve, outside air is drawn in, compressed, and sent to the aeration disc through the connecting pipe, the collector pipe, and the distributor pipe. The aeration disc releases a large number of bubbles, disturbing the ozone water and enhancing its contact with fruits and vegetables. In particular, it can penetrate into the interior and crevices of fruits and vegetables with complex structures, solving the problem of incomplete enzyme inactivation.

[0040] 3. In the linkage circulation mechanism, the reciprocating screw rotates to drive the drive gear to rotate. Through gear meshing, the driven gear and the rotating seat rotate, causing the conveying fan blades to run. The ozone water at the bottom of the treatment box is transported to the output pipe through the circulation pipe, and then sprayed to the top by the nozzle, forming an ozone water circulation. This soaks and sprays the fruits and vegetables to inactivate enzymes, improving the enzyme inactivation effect while increasing the utilization rate of ozone water.

[0041] 4. In the discharge mechanism, the upper and lower guide plates inside the discharge box are set at an angle, which can guide the enzyme-inactivated fruits and vegetables to be discharged smoothly and orderly, reduce collision damage, and ensure product quality. With the help of the hollow basket, fruits and vegetables to be soaked can be placed. The limiting post and the limiting plate work together to limit them. The telescopic spring buffers the impact force when fruits and vegetables are put in to avoid damage. At the same time, the height of the hollow basket can be changed by adjusting the positioning nut to adapt to the soaking needs of different amounts of fruits and vegetables. The hollow structure ensures that the ozone water can fully contact the fruits and vegetables, improving the enzyme inactivation effect.

[0042] 5. The ozone water propulsion drives the float and the striking rod to reciprocate, intermittently striking the perforated conveyor belt, causing the fruits and vegetables to vibrate so that they can fully contact the ozone water, improving the enzyme inactivation effect, and at the same time assisting in the drainage of fruits and vegetables.

[0043] 6. The absorbent cloth absorbs residual ozone water on the surface of fruits and vegetables, ensuring the subsequent soaking effect. The electric heating wire dries the absorbent cloth to maintain its water absorption capacity. The filter holes and drain seat work together to achieve ozone water circulation and reduce waste.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1: Please refer to Figure 1 - Figure 10This invention provides a technical solution: an enzyme-inactivating device for fruit and vegetable processing with automatic feeding capability, comprising a processing chamber 1, a cover plate 2 fixedly installed on the top of the processing chamber 1, a feeding control mechanism at the front end of the processing chamber 1, the feeding control mechanism including a feeding conveyor belt 3 fixedly installed on the top of the front end of the processing chamber 1, a servo motor 4 connected to the rear left end of the feeding conveyor belt 3, the servo motor 4 being fixedly connected to the left side of the processing chamber 1, and the feeding control mechanism further including a movable sealing plate 6 slidably disposed on the bottom surface of the front end of the cover plate 2, the front end of the cover plate 2... An electric telescopic rod 5 is fixedly installed on the top surface of the end. The front end of the electric telescopic rod 5 is fixedly connected to the top front end of the movable sealing plate 6. Limiting rods 7 are symmetrically installed on the top front end of the movable sealing plate 6. A positioning seat 8 is symmetrically installed on the top front end of the cover plate 2. The limiting rod 7 and the positioning seat 8 are slidably connected through each other. A support frame 9 is fixedly installed on the top front end of the processing box 1. A photoelectric sensor 10 is installed in the middle of the front end of the support frame 9. A control processor 11 is installed in the middle of the rear end of the support frame 9. The control processor 11, the photoelectric sensor 10 and the servo motor 4 are electrically connected.

[0061] In the above-described structure, when the device is started, the servo motor 4 starts working, and its output shaft rotates to drive the feeding conveyor belt 3. The fruits and vegetables to be processed are dispersed on the feeding conveyor belt 3 through the vibrating plate. As the feeding conveyor belt 3 moves, it is transported towards the processing box 1, realizing automatic feeding. During the feeding process, the photoelectric sensor 10 at the front middle of the support frame 9 will detect the amount of fruits and vegetables on the feeding conveyor belt 3 in real time. The photoelectric sensor 10 transmits the detected signal to the control processor 11 at the rear middle of the support frame 9. The control processor 11 analyzes and processes the signal.

[0062] When the amount of fruits and vegetables on the feeding conveyor belt 3 is sufficient, the control processor 11 will issue a command to stop the servo motor 4 and the feeding conveyor belt 3. At the same time, the control processor 11 will also control the electric telescopic rod 5 on the front top surface of the cover plate 2 according to the detection result. When feeding stops, the electric telescopic rod 5 moves forward, driving the movable sealing plate 6 to move forward and block the feed inlet of the processing box 1. When feeding is needed, the electric telescopic rod 5 retracts, driving the movable sealing plate 6 to move backward and open the feed inlet. During the movement of the movable sealing plate 6, the limiting rod 7 at the top front of its front end slides through the positioning seat 8 on the front top surface of the cover plate 2, which guides and limits the movement of the movable sealing plate 6, ensuring that the movable sealing plate 6 opens and closes smoothly and accurately.

[0063] Inside the processing box 1, transmission rods 12 are rotatably installed at equal intervals. The transmission rods 12 are distributed at equal intervals in an oblique direction inside the processing box 1. A hollow conveyor belt 13 is sleeved on the outer ring of the transmission rods 12. Baffles 14 are installed at equal intervals on the surface of the hollow conveyor belt 13. A servo motor 15 is connected to the left end of the top transmission rod 12. The servo motor 15 is fixedly connected to the left side of the processing box 1.

[0064] In the above-described structure, when the servo motor 15 is started, the output shaft rotation will directly drive the top transmission rod 12 to rotate. Since multiple transmission rods 12 are evenly spaced and obliquely distributed inside the processing box 1, the rotation of the top transmission rod 12 will cause the entire hollow conveyor belt 13 to circulate along the oblique trajectory. The baffles 14 installed at equal intervals on the surface of the hollow conveyor belt 13 play a key role in the operation of the conveyor belt. When fruits and vegetables enter the processing box 1 and fall on the hollow conveyor belt 13, the baffles 14 will block the fruits and vegetables, preventing them from slipping due to the oblique operation of the conveyor belt, and ensuring that the fruits and vegetables can move stably into the processing box 1 with the conveyor belt.

[0065] Meanwhile, the perforated structure of the perforated conveyor belt 13 will not obstruct the contact between the ozone water in the treatment box 1 and the fruits and vegetables, so that the fruits and vegetables can fully contact the ozone water during the transportation process, ensuring the uniformity and effectiveness of the enzyme inactivation treatment, and laying a good foundation for the subsequent enzyme inactivation process.

[0066] A piston aeration mechanism is provided on the left side of the front end of the treatment box 1. A drive motor 25 is connected to the top of the piston aeration mechanism. The drive motor 25 is fixedly connected to the left side of the treatment box 1. The piston aeration mechanism includes a sealing box 16 fixedly installed on the left side of the treatment box 1. A reciprocating lifting plate 17 is slidably arranged inside the sealing box 16. A reciprocating screw 18 passes through the middle of the reciprocating lifting plate 17. The upper and lower ends of the reciprocating screw 18 are rotatably connected to the sealing box 16. The piston aeration mechanism also includes air inlet valves 19 symmetrically installed on the upper and lower ends of the left side of the sealing box 16. Air outlet valves 20 are symmetrically installed on the upper and lower ends of the right side of the sealing box 16. A connecting pipe 21 is fixedly connected to the air outlet end of the air outlet valve 20. A collecting pipe 22 is connected to the air outlet end of the connecting pipe 21. The collecting pipe 22 is fixedly connected to the left side of the treatment box 1. Diverting pipes 23 are installed at equal intervals on the collecting pipe 22 inside the treatment box 1. Aeration discs 24 are installed at equal intervals on the top of the diverting pipes 23.

[0067] In the above-described structure, when the drive motor 25 operates, it drives the reciprocating screw 18 connected to it to rotate. Since the upper and lower ends of the reciprocating screw 18 are rotatably connected to the sealing box 16, and the reciprocating lifting plate 17 passes through the middle of the reciprocating screw 18 and is slidably connected to the inside of the sealing box 16, the rotation of the reciprocating screw 18 is converted into the reciprocating up and down movement of the reciprocating lifting plate 17 within the sealing box 16. During the lifting process of the reciprocating lifting plate 17, air can be introduced and discharged through the air inlet valve 19 and air outlet valve 20 at the upper and lower ends, respectively. The discharged gas enters the interior of the connecting pipe 21 and is collected in the collection pipe 22. The collection pipe 22 is fixedly connected to the left side of the treatment box 1. The air enters the interior of the treatment box 1 through the collection pipe 22, and is then divided by the diversion pipe 23 on the collection pipe 22. Finally, a large number of bubbles are released by the aeration discs 24 installed at equal intervals on the top of the diversion pipe 23. These bubbles enter the ozone water in the treatment box 1, which can disturb the water and enhance the contact between the ozone water and fruits and vegetables, especially penetrating the interior and crevices of fruits and vegetables with complex structures, thereby improving the enzyme inactivation effect.

[0068] The piston aeration mechanism is connected to the top two sides of a linkage circulation mechanism. The linkage circulation mechanism includes a drive gear 26 fixedly sleeved on the outer ring of the top of the reciprocating screw 18. Driven gears 27 mesh parallel to each other on both sides of the drive gear 26. A rotating seat 28 is fixedly connected to the inner ring of the driven gear 27. Conveying fan blades 29 are symmetrically distributed inside the rotating seat 28. A positioning tube 30 is rotatably connected to the outer ring of the rotating seat 28. The positioning tube 30 is set in a split manner. The upper and lower positioning tubes 30 are fixedly connected to each other through a connecting seat 31. The linkage circulation mechanism also includes circulation tubes 32 fixedly installed at the upper and lower ends of the positioning tube 30. The upper and lower circulation tubes 32 are connected through the treatment box 1. The upper and lower circulation tubes 32 are fastened to the treatment box 1 through a flange 33. An output tube 34 is fixedly connected to the right end of the upper circulation tube 32. Spray nozzles 35 are installed at equal intervals at the bottom of the output tube 34.

[0069] In the above-described structure, when the drive motor 25 in the piston aeration mechanism drives the reciprocating screw 18 to rotate, the drive gear 26 fixedly sleeved on the outer ring of the top of the reciprocating screw 18 rotates synchronously. Since the drive gear 26 meshes parallel with the driven gears 27 on both sides, the rotation of the drive gear 26 will drive the two driven gears 27 to rotate simultaneously. Since the inner ring of the driven gear 27 is fixedly connected to the rotating seat 28, the rotation of the driven gear 27 will drive the rotating seat 28 to rotate together. The outer ring of the rotating seat 28 is rotatably connected to the positioning tube 30. The positioning tube 30 is fixed to the upper and lower parts through the connecting seat 31. This structure ensures the stability of the rotating seat 28 during rotation. The conveying fan blades 29 symmetrically distributed inside the rotating seat 28 rotate with the rotating seat 28, thereby generating suction and conveying force.

[0070] The circulation pipes 32, which are fixedly installed at both ends of the positioning pipe 30, are connected through the treatment box 1 and fastened by the flange 33 to ensure the sealing and stability of the connection. Under the action of the conveying fan blades 29, the ozone water at the bottom of the treatment box 1 is sucked into the lower circulation pipe 32 and transported through the inside of the positioning pipe 30 to the upper circulation pipe 32. The right end of the upper circulation pipe 32 is fixedly connected to the output pipe 34. The ozone water enters the output pipe 34 through the circulation pipe 32 and is then sprayed out from the nozzles 35 installed at equal intervals at the bottom of the output pipe 34, falling onto the fruits and vegetables in the treatment box 1. This forms a circulation of ozone water, allowing the ozone water to repeatedly contact the fruits and vegetables, which not only improves the enzyme inactivation effect but also increases the utilization rate of ozone water.

[0071] The bottom rear end of the cover plate 2 is fixedly connected to the discharge box 36. The discharge box 36 is installed obliquely with an upper guide plate 37 and a lower guide plate 38, which can guide the discharge of fruits and vegetables. The processing box 1 is fixedly installed with a partition plate 39. The rear side of the partition plate 39 divides the processing box 1 into a soaking chamber 40. A hollow basket 41 is movably placed inside the soaking chamber 40.

[0072] The above-described structure allows fruits and vegetables to be transported to the discharge box 36 at the bottom rear end of the cover plate 2 after undergoing enzyme inactivation treatment inside the processing box 1. The upper guide plate 37 and lower guide plate 38 installed at an angle inside the discharge box 36 will act as guides. The fruits and vegetables first come into contact with the upper guide plate 37. Since the upper guide plate 37 is angled, the fruits and vegetables will slide down along its tilt direction and then fall onto the lower guide plate 38. They will then continue to move along the angle of the lower guide plate 38 and finally be discharged smoothly from the discharge box 36. This angled design of the double guide plates can effectively slow down the falling speed of the fruits and vegetables, avoid collision damage caused by direct fall during the discharge process, and ensure the integrity of the enzyme-inactivated fruits and vegetables.

[0073] In terms of soaking treatment, the partition plate 39 fixedly installed inside the treatment box 1 divides the rear side of the box into an independent soaking chamber 40. This chamber can be used to soak and preserve fruits and vegetables with natural polyphenol fruit and vegetable coating agents. When soaking treatment is required, the fruits and vegetables to be treated are discharged through the discharge box 36 into the hollow basket 41. Since the hollow basket 41 adopts a hollow design, the natural polyphenol fruit and vegetable coating agents in the soaking chamber 40 can smoothly penetrate into the hollow basket 41 and fully contact the fruits and vegetables to ensure the soaking treatment effect. When discharging, the hollow basket 41 can be lifted and disassembled to achieve convenient discharge.

[0074] Example 2: Based on Example 1, the present invention adopts the following... Figure 11 - Figure 12The technical solution shown further discloses that the bottom of both ends of the hollow basket 41 is equipped with limit posts 42 at equal intervals, the outer ring of the limit post 42 is fitted with a limit plate 43, the inner side of the limit plate 43 is fixedly connected to the outer facade of the processing box 1, the limit post 42 is slidably connected to the limit plate 43, the outer ring of the limit post 42 is fitted with a telescopic spring 44, the top of the telescopic spring 44 is fixedly connected to the bottom surfaces of both ends of the hollow basket 41, and the bottom surface of the middle limit post 42 is threaded with a positioning nut 45;

[0075] The above structure is designed so that when fruits and vegetables are placed into the hollow basket 41, the weight of the fruits and vegetables will cause the hollow basket 41 to exert a certain pressure downward. At this time, the telescopic spring 44 on the outer ring of the limiting post 42 will be compressed. The top of the telescopic spring 44 is fixedly connected to the bottom surface of both ends of the hollow basket 41. Its elasticity can effectively buffer the impact force when fruits and vegetables are put in, reduce the possibility of fruits and vegetables being damaged due to collision, and protect the integrity of fruits and vegetables.

[0076] When the positioning nut 45, which is threaded on the bottom surface of the central limiting post 42, is tightened upwards or downwards, the downward movement distance of the limiting post 42 can be limited, thereby controlling the position of the hollow basket 41 in the soaking chamber 40, ensuring that it is at a suitable soaking depth, and making it easy to adjust the position of the hollow basket 41 according to actual needs to adapt to the soaking treatment of different quantities or different types of fruits and vegetables.

[0077] Example 3: Based on Example 1, the present invention adopts the following... Figure 13 The technical solution shown further discloses that guide rails 46 are symmetrically installed on the rear inner wall of the processing box 1, a float plate 47 is slidably installed inside the guide rails 46, and a striking rod 48 is fixedly installed on the top surface of the float plate 47. The top of the striking rod 48 is a spherical structure.

[0078] The above-mentioned structure design provides a stable sliding track for the float plate 47 on the symmetrical guide rail 46 on the inner wall of the rear side of the treatment tank 1. When the aeration disc 24 is working, it will push the ozone water in the treatment tank 1 to flow upward, generating an upward thrust. This thrust acts on the float plate 47, causing it to slide upward along the guide rail 46, and at the same time, it drives the striking rod 48 on the top surface of the float plate 47 to rise synchronously.

[0079] When the perforated conveyor belt 13 is running, the baffle 14 on its surface moves with the conveyor belt. When the baffle 14 contacts the spherical structure at the top of the striking rod 48, it will squeeze the striking rod 48, forcing the striking rod 48 to drive the float 47 to move downward along the guide rail 46. As the perforated conveyor belt 13 continues to run, the baffle 14 separates from the striking rod 48, the squeezing effect disappears, and under the upward thrust of the ozone water, the float 47 and the striking rod 48 will move upward again. This cycle continues, and the float 47 moves back and forth in the guide rail 46. The striking rod 48 then repeatedly strikes the perforated conveyor belt 13. The vibration generated by the striking is transmitted to the fruits and vegetables on the perforated conveyor belt 13, causing the fruits and vegetables to vibrate slightly, thus making more full contact with the ozone water. At the same time, when the fruits and vegetables are transported to the top of the perforated conveyor belt 13, the vibration helps to drain excess water from the surface of the fruits and vegetables.

[0080] Example 4: Based on Example 1, the present invention adopts the following... Figure 14 The technical solution shown further discloses that the upper guide plate 37 and the lower guide plate 38 are provided with filter holes 49 in a rectangular array inside, the upper guide plate 37 and the lower guide plate 38 are inlaid with electric heating wires 50 at equal intervals inside, the top surface of the upper guide plate 37 and the lower guide plate 38 is connected with absorbent cloth 51, and the bottom of the discharge box 36 is equipped with a drain seat 52.

[0081] The above structure is designed so that when the enzyme-inactivated fruits and vegetables are transported to the discharge box 36 via the perforated conveyor belt 13 and slide down the surface of the upper guide plate 37 and the lower guide plate 38, the residual ozone water on the surface of the fruits and vegetables will first come into contact with the absorbent cloth 51. The capillary structure of the absorbent cloth 51 will absorb this residual moisture and reduce the water content on the surface of the fruits and vegetables.

[0082] As the water absorption process continues, the absorbent cloth 51 gradually becomes saturated. At this point, the electric heating wire 50 is energized to generate heat, which dries the absorbent cloth 51, restoring its water absorption capacity and maintaining its continuous absorption of moisture from the surface of fruits and vegetables.

[0083] When there is a large amount of residual ozone water on the surface of fruits and vegetables, some of the water will pass through the filter hole 49 and flow into the space below the upper guide plate 37 and the lower guide plate 38, and collect at the bottom of the discharge box 36. The drain seat 52 at the bottom of the discharge box 36 can discharge the collected ozone water. If the drain seat 52 is connected to the front of the treatment box 1, the ozone water can be recycled and reused, avoiding waste of resources.
