Description

Technical Field

[0001] This invention relates to the field of pre-cleaned vegetable production technology, specifically to a foam elimination device for a pre-cleaned vegetable production line. Background Technology

[0002] Fruit and vegetable processing involves continuous processes such as raw material cutting, soaking and washing, impurity removal and defoaming, and starch separation. Root vegetables such as potatoes, lotus roots, and yams release a large amount of starch after cutting. When the starch dissolves in the washing water, it is easily agitated by air bubbles and water flow to generate a large amount of foam. The foam can absorb mud, pesticide residues, and vegetable scraps, causing secondary pollution of the materials. It can also clog water channels and reduce water recycling rates, seriously restricting the efficiency of continuous operation of the production line. Therefore, the use of dedicated defoaming equipment in clean vegetable production lines has become an industry necessity.

[0003] Currently, there are defoaming equipment solutions available on the market for processed vegetables. For example, patent CN202320013758.3 discloses a foam elimination device for a processed vegetable production line. This device is equipped with a defoaming machine, a starch recovery tank, a washing tank, a lifting device, a centrifugal separation mechanism, and a foam receiving structure. It relies on a cutting motor to drive an impeller to break up the foam, and a centrifuge to separate the starch. The foam and starch are then returned to the starch recovery tank for centralized processing, which alleviates the problem of foam accumulation in the washing tank to a certain extent. At the same time, it can recover starch, which greatly improves the work efficiency compared to manual static defoaming.

[0004] However, the cleaning method described in the aforementioned patent literature is simplistic. It relies solely on the bubble pipeline within the tank to generate bubbles for basic rinsing, resulting in limited removal of starch and other adhering substances from the material surface. Furthermore, relying solely on the impeller to statically break up the foam means that the foam adhering to the vegetable surface cannot be quickly removed, leaving behind a large amount of tiny foam adhering materials that affect the cleanliness of the finished product.

[0016] The technological advancements achieved by this invention due to the adoption of the above technical solutions are as follows: This invention provides a foam elimination device for a clean vegetable production line. It uses multiple independent receiving boxes to hold the cut clean vegetables. The materials are loaded in a dispersed manner and driven by a swinging component to swing back and forth. The first rack, the second rack and the first gear mesh alternately to achieve stable back and forth swinging. During the swinging process, the materials are fully tumbled. While the materials are tumbling, the cleaning component sprays and blows air on the tumbling materials. Compared with the prior art, it can effectively remove the tiny foams and starch particles attached to the surface of the vegetables quickly, improve the cleaning effect and enhance the cleanliness of the finished product.

[0017] This invention integrates a cutting box, a cutting cage, a first transport and transfer mechanism, a cleaning box, and a second material distribution and conveying component. The cutting, material retrieval and transfer, batch cleaning, dynamic defoaming, and material discharge processes are linked and coordinated, allowing for uninterrupted operation of the production line without frequent shutdowns to clean residues and recover starch. This effectively increases the effective operating time of the production line and is suitable for large-scale continuous processing needs. At the same time, a rotating mesh with a baffle plate is set up to transfer materials. The guide groove and ball bearings automatically control the opening and closing of the baffle plate, and the material retrieval and discharge are automatically switched to prevent chopped vegetables from falling back into the cleaning tank and repeatedly mixing and foaming, thus reducing secondary pollution and repeated defoaming load.

[0018] In this invention, the cleaning tank is equipped with a water spray pipe and an air spray pipe that can swing back and forth. The cylinder drives the third rack to drive multiple sets of second gears to rotate synchronously. The water spray head washes and the air spray head blows air, which has a dual effect.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary details.

[0024] This invention provides a foam elimination device for a clean vegetable production line, as per the attached instruction manual. Figure 1 To be continued Figure 8 It can be seen that a foam elimination device for a clean vegetable production line mainly includes the following parts or components: cutting box 10, cutting cage 11, first transport component 50, washing box 12, and washing component 40.

[0025] In this invention, the cutting box 10 is provided with an inlet 101 and an outlet 102 at both ends; the cutting cage 11 is located inside the cutting box 10 and close to the inlet 101, the cutting cage 11 is provided with a feed inlet, and the cutting cage 11 is provided with a cutting component 60; the first transport component 50 is located inside the cutting box 10 between the cutting cage 11 and the outlet 102, and the side of the cutting cage 11 facing the first transport component 50 is provided with an openable cage door 111; the cleaning box 12 is located on one side of the cutting box 10, and a second transport component 20 is provided inside it, and a plurality of receiving boxes 121 are spaced apart on the second transport component 20. The first transport component 50 transports the cut material sequentially to each receiving box 121, and the receiving box 121 is provided with a plurality of first water passage holes 122; the cleaning component 40 is located inside the cleaning box 12, and the cleaning component 40 is used to clean the material in each receiving box 121, and during cleaning, the swing component 30 drives the receiving box 121 to swing.

[0026] Washing water enters from the inlet 101 of the cutting box 10, and raw materials are fed into the inlet of the cutting cage 11. The cutting component 60 cuts and crushes root vegetables. After cutting, the side door 111 of the cutting cage 11 is opened, and the material falls into the first transport component 50, which then transfers it upwards to the washing box 12. The material falls sequentially into the independent receiving boxes 121 arranged at intervals on the second transport component 20. The receiving boxes 121 are filled with first water holes 122, allowing washing water to pass through freely. The washing component 40 inside the washing box 12 is activated, and water and air flow into the boxes. The vegetables are simultaneously rinsed and aerated to remove foam. During the cleaning process, the swing component 30 drives the receiving box 121 to swing back and forth. The material is fully tumbled in the water, removing starch, foam, and mud from the surface of the food. After the receiving box 121 leaves the cleaning area, the limiting component constrains the posture of the receiving box 121, stopping its swing and maintaining a stable state parallel to the first conveyor belt 21 for forward conveying. After cleaning and defoaming are completed, the second transport component 20 continues to transport the receiving box 121 to complete the discharge. Wastewater containing starch and foam is discharged from the outlet 102 of the cutting box 10.

[0027] Specifically, the cutting box 10 is equipped with a liquid level sensor and an automatic water replenishment valve. The water level in the cutting box 10 is automatically regulated to prevent foam overflow due to excessive water level or insufficient cleaning due to excessive water level. A photoelectric sensor switch is installed at the cage door 111. The cage door 111 will open automatically after the material is cut, eliminating the need for manual opening and closing and improving the level of automation.

[0028] As one embodiment, according to the appendix to the specification Figure 2It is known that the second transport component 20 includes two rotatable first conveyor belts 21, symmetrically arranged on both sides inside the cleaning box 12. Each receiving box 121 is located between the two first conveyor belts 21. Each receiving box 121 has a first fixed shaft 22 and a second fixed shaft 23 fixed on both sides. The first fixed shaft 22 and the second fixed shaft 23 are rotatably connected to the two first conveyor belts 21 respectively. When cleaning the material in the receiving box 121, the free end of the first fixed shaft 22 is connected to the swing component 30, and the free end of the second fixed shaft 23 is separated from the limiting component. After cleaning, the free end of the second fixed shaft 23 is connected to the limiting component, and the free end of the first fixed shaft 22 is separated from the swing component 30.

[0029] The first conveyor belt 21 continues to move forward, driving the receiving box 121 forward as a whole. When cleaning the material in the receiving box 121, the swing component 30 drives the first fixed shaft 22 to rotate back and forth, causing the receiving box 121 to swing left and right. After cleaning, the swing component 30 disengages from the first fixed shaft 22, and the second fixed shaft 23 is connected to the limiting component, and the posture of the second fixed shaft 23 is constrained, so that the receiving box 121 stops swinging and only maintains a stable posture parallel to the first conveyor belt 21 to be conveyed forward in a straight line, thereby completing the unloading.

[0030] Specifically, the first conveyor belts 21 on both sides are equipped with synchronous servo motors to ensure that the conveying speed is completely synchronized and to prevent the receiving box 121 from being tilted or jammed due to force.

[0031] As one embodiment, according to the appendix to the specification Figure 3 It is known that the swing assembly 30 includes a plurality of first racks 31, which are arranged in parallel and spaced apart in the cleaning tank 12 and located on the side corresponding to the first fixed shaft 22; a plurality of second racks 32 are located above the first racks 31, and each second rack 32 is fixed in the cleaning tank 12 between two adjacent first racks 31. The second racks 32 are parallel to and opposite to the first racks 31. The first gear 33 fixed on the first fixed shaft 22 meshes with the first racks 31 and the second racks 32 in an alternating manner.

[0032] When the receiving box 121 moves forward with the first conveyor belt 21 to the cleaning station, the first gear 33 at the end of the first fixed shaft 22 alternately meshes with the lower first rack 31 and the upper second rack 32. When the first gear 33 moves, it rotates alternately in both directions, causing the receiving box 121 to swing back and forth with the first fixed shaft 22 as the fulcrum, so that the material can be tumbled and rubbed in the receiving box 121 to peel off the attached foam and starch.

[0033] As one embodiment, according to the appendix to the specification Figure 5It is known that the limiting component includes a limiting groove 13, which is fixed inside the cleaning box 12 and located on the side corresponding to the second fixed shaft 23; the outline of the limiting groove 13 is the same as the outline of the first conveyor belt 21, the upper end of the limiting groove 13 is provided with a notch 131, the swing component 30 is opposite to the notch 131, and the free end of the second fixed shaft 23 is fixed with a sliding plate 231, which is adapted to the limiting groove 13.

[0034] The side wall of the cleaning box 12 is fixed with a limiting groove 13 whose contour is consistent with the trajectory of the first conveyor belt 21. A notch 131 is reserved at the upper end of the groove for the sliding plate 231 to enter and exit. In the cleaning station area: the sliding plate 231 at the end of the second fixed shaft 23 on the right side of the receiving box 121 does not contact the limiting groove 13. In the straight discharge area: after the receiving box 121 is disengaged from the meshing area of ​​the first rack 31 and the second rack 32, the sliding plate 231 is slidably connected to the limiting groove 13. The limiting groove 13 constrains the sliding plate 231 and restricts the second fixed shaft 23 from deflecting. Together with the first fixed shaft 22 that has lost power, the attitude of the receiving box 121 is locked, so that the receiving box 121 is kept parallel to the first conveyor belt 21 and is transported forward smoothly, preventing the material from overturning and spilling when discharging.

[0035] As one embodiment, according to the appendix to the specification Figure 4 It is known that a second conveyor belt 14 is provided in the cleaning box 12 between the two first conveyor belts 21. Multiple arc-shaped grooves 141 are fixedly provided on the second conveyor belt 14 at intervals. Multiple protrusions 142 are provided at intervals in the arc-shaped grooves 141. The multiple arc-shaped grooves 141 correspond one-to-one with multiple receiving boxes 121. A receiving plate 15 is slidably provided in the receiving box 121. The lower end of the receiving plate 15 is connected to the bottom of the receiving box 121 through multiple first springs 152. Multiple second water passage holes 151 are provided on the receiving plate 15. A vibrating rod 154 is fixedly provided at the lower end of the receiving plate 15. The lower end of the vibrating rod 154 passes through the bottom of the receiving box 121 and is slidably connected to the corresponding arc-shaped groove 141. A boss 153 is fixedly provided on the vibrating rod 154 below the bottom of the receiving box 121.

[0036] During equipment operation, the second conveyor belt 14 moves synchronously, and the vibrating rod 154 swings with the receiving box 121. The vibrating rod 154 swings within the arc-shaped groove 141, and the lower end of the vibrating rod 154 is sequentially slidably connected to multiple protrusions 142 within the arc-shaped groove 141. When the vibrating rod 154 swings to the high point of the protrusion 142, it drives the receiving plate 15 to rise upward, stretching the first spring 152. When the vibrating rod 154 swings to the low point of the protrusion 142, the first spring 152 rebounds, and the receiving plate 15 quickly... As the food falls, it generates continuous high-frequency vibration. The vibration of the receiving plate 15 causes the food to shake, and starch and small vegetable residues sink and separate through the second water passage 151. At the same time, the vibration can break up the tiny foam on the surface of the food, enhancing the defoaming effect. The boss 153 of the vibrating rod 154 limits the vibration rod 154 to prevent it from completely falling out of the arc groove 141. The entire vibration process is synchronized with the two working conditions of the receiving box 121: the left and right swing of the washing section and the straight movement of the discharge section. The dual effect improves the defoaming and starch removal effect.

[0037] Specifically, the lower end of the vibrating rod 154 is a roller to reduce wear and running resistance.

[0038] Specifically, the second conveyor belt 14 is equipped with a servo motor to ensure the conveying speed, so that the traveling speed of the arc groove 141 is consistent with that of the vibrating rod 154.

[0039] As one embodiment, according to the appendix to the specification Figure 6 It is known that the cleaning assembly 40 includes multiple water spray pipes 41, which are parallel and spaced apart and rotated in the cleaning tank 12 above the swing assembly 30. Multiple water spray nozzles 42 are provided on the water spray pipes 41, and the ends of the water spray pipes 41 are connected to the water source through the first rotary joint 43. Each air jet pipe 44 is rotated between two adjacent water spray pipes 41. Multiple air jet nozzles 45 are provided on the air jet pipe 44, and the ends of the air jet pipe 44 are connected to the air source through the second rotary joint 46. Second gears 47 are fixed on both the air jet pipe 44 and the water spray pipes 41. A third rack 48 is slidably mounted on the cleaning tank 12 and slides horizontally back and forth under the drive of the cylinder 481. The third rack 48 meshes with multiple second gears 47 respectively.

[0040] Cylinder 481 drives the third rack 48 to slide horizontally back and forth. The third rack 48 meshes with the second gear 47 at the ends of all water spray pipes 41 and air spray pipes 44, driving all water spray pipes 41 and air spray pipes 44 to rotate synchronously in both directions. The water spray head 42 swings with the water spray pipe 41 to spray high pressure and wash away starch and mud on the surface of the food. The air spray head 45 swings synchronously to spray high pressure airflow and blow away surface foam. Water and air work together to complete cleaning and defoaming. This cleaning action only works continuously at the swing cleaning station of the receiving box 121. After the receiving box 121 enters the straight discharge section, the cleaning component 40 can be turned off synchronously to save water and air energy consumption.

[0041] As one embodiment, according to the appendix to the specification Figure 7It is known that the first transport component 50 includes two third conveyor belts 51, which are arranged parallel and inclined inside the cutting box 10. Their lower ends are opposite to the cage door 111, and their higher ends are located above the washing box 12. The rotating net 52 is arranged between the two third conveyor belts 51, and the outline of the rotating net 52 is the same as that of the third conveyor belts 51. The two sides of the rotating net 52 are fixedly connected to the two third conveyor belts 51 respectively. The rotating net 52 is provided with a plurality of third water passage holes 53. A plurality of material collection boxes 54 are fixedly arranged on the rotating net 52 at intervals. One end of the material collection box 54 is provided with a feed port for material to enter into the material collection box 54.

[0042] After the cutting is completed and the cage door 111 is opened, the material falls into front of the first transport component 50. The material scooping box 54, which rotates with the third conveyor belt 51, scoops the material from the feed port into the interior. The third conveyor belt 51 drives the rotating net 52 to tilt upward and lift it. The water flows back to the cutting box 10 from the third water passage 53. When the material is transferred to the position above the cleaning box 12, the material scooping box 54 flips over and the material falls downward to the receiving box 121 below. It is then transported by the second transport component 20 into the swing cleaning process. After the cleaning is completed, the material is switched to the straight state for discharge.

[0043] Specifically, the third conveyor belts 51 on both sides are equipped with synchronous servo motors to ensure that the conveying speed is completely synchronized.

[0044] As one embodiment, according to the appendix to the specification Figure 7 Appendix Figure 8 It is known that a baffle plate 55 is provided at the feed inlet. The end of the baffle plate 55 passes through the rotating mesh 52 and is fixed with a baffle shaft 56. A guide plate 57 is fixed between the two third conveyor belts 51. A guide groove 571 is provided on the guide plate 57. A ball bearing 561 is provided at the free end of the baffle shaft 56. The ball bearing 561 is slidably connected to the guide groove 571. When it is necessary to scoop or discharge material, the baffle plate 55 is disengaged from the feed inlet by the ball bearing 561 and the baffle shaft 56 under the action of the guide groove 571. When it is not necessary to scoop or discharge material, the baffle plate 55 is tightly attached to the feed inlet by the ball bearing 561 and the baffle shaft 56 under the action of the guide groove 571.

[0045] The feed inlet of the scooping box 54 is equipped with a baffle plate 55, which is connected to a baffle shaft 56. The ball bearing 561 at the end of the shaft is embedded in the guide groove 571 of the guide plate 57. When the scooping box 54 descends to the material retrieval stage of the cutting cage 11, the trajectory of the guide groove 571 causes the ball bearing 561, the baffle shaft 56, and the baffle plate 55 to automatically open, and the material enters the scooping box 54. When the scooping box 54 tilts upward and is lifted for transfer, the trajectory of the guide groove 571 drives the baffle plate 55 to re-fit against the feed inlet, sealing the box and preventing the food from falling during the lifting process. When the scooping box 54 runs to the discharge position above the washing box 12, the guide groove 571 drives the baffle plate 55 to open again, and the material falls completely into the receiving box 121. It then enters the swing washing station with the first conveyor belt 21. After washing, it switches to a straight and horizontal posture for unloading.

[0046] Specifically, the cross-section of the guide groove 571 is the same as the cross-section of the ball 561, and the ball 561 will not come out inside the guide groove 571.

[0047] Specifically, a cleaning opening is reserved on the outside of the guide plate 57 to facilitate the cleaning of accumulated starch and vegetable scraps in the trough.

[0048] As one embodiment, according to the appendix to the specification Figure 7 It is known that the cutting assembly 60 includes a cutting shaft 61, which is located inside the cutting cage 11 and rotates under the drive of the first motor 62. The cutting shaft 61 is provided with a cutting blade 63.

[0049] After the raw materials are fed into the cutting cage 11, the first motor 62 drives the cutting shaft 61 to rotate at high speed, and the cutting blade 63 cuts root vegetables such as potatoes and lotus roots. After the cutting is completed, the cage door 111 is opened.

[0050] As one embodiment, according to the appendix to the specification Figure 1 It is known that the cleaning box 12 above the swing assembly 30 is provided with a water collection tank 70, the water collection tank 70 is provided with a drain outlet, and a material receiving box 72 for receiving materials is provided on one side of the water collection tank 70.

[0051] A water collection tank 70 is installed above the swing cleaning area of ​​the receiving box 121 to collect the overflow wastewater from the spraying and cleaning. The foam and starch-containing wastewater generated by the receiving box 121 during the swing cleaning stage flow into the water collection tank 70 and are discharged uniformly through the bottom drain outlet for centralized starch recovery and water treatment. After cleaning, the receiving box 121 switches to a straight conveying state parallel to the first conveyor belt 21, which smoothly conveys the cleaned vegetables to the end, where they fall into the conveying box 72 for centralized collection and enter the next processing step.

[0052] This invention provides a foam elimination device for a clean vegetable production line. The specific usage method is as follows: Washing water enters from the inlet 101 of the cutting box 10, and raw materials are fed into the inlet of the cutting cage 11. The cutting component 60 cuts and crushes root vegetables. After cutting, the side door 111 of the cutting cage 11 is opened, and the material falls into the first transport component 50, which then transfers it upwards to the washing box 12. The material falls sequentially into the independent receiving boxes 121 arranged at intervals on the second transport component 20. The receiving boxes 121 are filled with first water holes 122, allowing washing water to pass through freely. The washing component 40 inside the washing box 12 is activated, and water and air flow into the boxes. The vegetables are simultaneously rinsed and aerated to remove foam. During the cleaning process, the swing component 30 drives the receiving box 121 to swing back and forth. The material is fully tumbled in the water, removing starch, foam, and mud from the surface of the food. After the receiving box 121 leaves the cleaning area, the limiting component constrains the posture of the receiving box 121, stopping its swing and maintaining a stable state parallel to the first conveyor belt 21 for forward conveying. After cleaning and defoaming are completed, the second transport component 20 continues to transport the receiving box 121 to complete the discharge. Wastewater containing starch and foam is discharged from the outlet 102 of the cutting box 10.
