Abstract
Description
Technical Field
[0001] This invention relates to the field of fruit and vegetable beverage production technology, specifically to a homogenizing feeding device for fruit and vegetable beverages. Background Technology
[0002] Fruit and vegetable beverages are widely favored by consumers due to their rich content of vitamins, dietary fiber, and other nutrients. In the industrial production of fruit and vegetable beverages, the feeding process is one of the key steps affecting product quality. Its core requirements are to achieve uniform mixing and fine crushing of materials (i.e., homogenization) to prevent the agglomeration of fruit pulp, peels, and other particles, while also preventing waste and hygiene hazards caused by material residue on the inner walls of the equipment.
[0003] Currently, the main feeding devices for fruit and vegetable beverages on the market employ methods such as single auger conveying, mixing paddles, or ultrasonic homogenization. Among these, single auger conveying devices can only achieve axial pushing of materials, resulting in poor radial mixing within the tank and a tendency for localized material accumulation, leading to insufficient homogenization. Subsequent processing requires additional homogenization equipment, increasing production time and costs. While mixing paddles can achieve a certain degree of mixing, the fixed mixing trajectory makes it easy for materials to clump together in dead zones. Furthermore, gaps exist between the paddle and the tank wall, making it easy for material residue to remain, resulting in difficult cleaning and potential bacterial growth over long-term use, affecting beverage hygiene and safety. Although ultrasonic homogenization devices offer good homogenization, they are costly, energy-intensive, and poorly adaptable to high-viscosity materials, making them unsuitable for large-scale industrial production. Summary of the Invention

The first gear at the lower end of the first auger meshes alternately with the first rack and the second rack. A plurality of first guide cylinders are fixedly provided at the upper ends of the first rack and the second rack. A plurality of first guide shafts are fixedly provided at the top of the scraper.

[0015] The technological advancements achieved by this invention due to the adoption of the above technical solutions are as follows: This invention provides a homogenizing feeding device for fruit and vegetable beverages. A drive unit rotates a turntable, which in turn, via a transmission assembly, causes a first auger to revolve around the center of the turntable. Simultaneously, during this revolution, the first auger reciprocates radially along the turntable. This, combined with the coaxial arrangement of a second auger, forms a composite motion trajectory of revolution and radial reciprocating movement. This structure overcomes the limitation of fixed auger motion trajectories in existing devices, allowing the first auger to cover the entire radial area from the center to the edge of the container, preventing localized material accumulation and ensuring sufficient contact and collision between materials at different locations. Furthermore, the first auger rotates in one direction throughout its reciprocating motion, continuously generating stable shearing and crushing forces, effectively breaking down fruit pulp and other particles, preventing particle agglomeration and improving material homogenization. This eliminates the need for additional homogenizing equipment, simplifying the production process.
[0016] In this invention, multiple scrapers are provided at the lower end of the second auger and connected to the lower end of the first auger via a connecting assembly. During the movement of the first auger, the scrapers rotate synchronously with the second auger, and the side of the scraper facing the direction of rotation is inclined, which can closely fit the bottom of the can and scrape up the fruit particles at the bottom, so that the particles at the bottom can smoothly enter the first and second augers.
[0017] In this invention, the three movements of the first auger are integrated with the linkage movements of the second auger and scraper through the organic integration of mechanical structures such as transmission components and connecting components. The overall structure is compact, reducing the space occupied by the equipment. The transmission components are made of wear-resistant and corrosion-resistant high-strength alloy materials, which extends the service life and reduces the failure rate. At the same time, the transmission of each motion mechanism is smooth, eliminating the need for a complex electronic control system for multi-action coordinated control, reducing the failure points of electronic components, and simplifying the installation and maintenance process of the equipment.
[0018] In this invention, the meshing design of multiple first bevel gears in the transmission assembly with the second bevel gear on the fixed shaft enables the synchronous linkage of the turntable's revolution and the first auger's rotation and radial reciprocating movement, eliminating the need for an additional power source to drive unidirectional motion and improving transmission efficiency. The connecting assembly, through the staggered meshing structure of the first rack, second rack, and first gear, ensures the stability of the first auger's unidirectional rotation during reciprocating movement.

Detailed Implementation
[0022] 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.
[0023] This invention provides a homogenizing feeding device for fruit and vegetable beverages, as per the attached instruction manual. Figures 1 to 9 It can be seen that a homogenizing feeding device for fruit and vegetable beverages mainly includes the following parts or components: tank body 10, turntable 11, first auger 12, and second auger 13. The connection relationship of each part or component is as follows.
[0024] In this invention, the tank body 10 has an inlet 101 at the top and an outlet 102 at the bottom; the turntable 11 is horizontally positioned inside the tank body 10 above the inlet 101 and rotates under the drive of the drive component 80; multiple first augers 12 are located inside the tank body 10 below the turntable 11 and are evenly distributed along the circumference of the turntable 11. The upper end of each first auger 12 is connected to the lower surface of the turntable 11 through a transmission component 20. When the turntable 11 rotates, the transmission component 20 drives the first augers 12 to revolve around the center of the turntable 11. During the revolution... The transmission assembly 20 drives the first auger 12 to reciprocate along the radial direction of the turntable 11; the second auger 13 is vertically arranged in the tank 10 below the turntable 11 and is coaxial with the middle of the turntable 11. Its upper end is connected to multiple transmission assemblies 20 through a connecting plate 131. The lower end of the second auger 13 is provided with multiple scrapers 14. Each scraper 14 is connected to the lower end of the corresponding first auger 12 through a connecting assembly 40. When the first auger 12 reciprocates along the radial direction of the turntable 11, the first auger 12 always rotates in one direction under the action of the connecting assembly 40.
[0025] The fruit and vegetable materials to be processed are fed into the tank 10 through the feed inlet 101 at the top of the tank 10. The materials fall naturally into the tank 10. The drive unit 80 is activated, which drives the turntable 11 to rotate around its central axis (coaxial with the second auger 13) inside the tank 10. When the turntable 11 rotates, it drives multiple first augers 12 to revolve synchronously around the center of the turntable 11 through the transmission component 20. At the same time, during the revolution, the transmission component 20 converts the rotational motion of the turntable 11 into the reciprocating movement of the first augers 12 along the radial direction of the turntable 11. This allows the first augers 12 to cover the entire area of the tank 10 while simultaneously sweeping radially from the center to the edge of the turntable 11, forming an all-round agitation of the materials inside the tank 10. During the radial reciprocating movement of the first augers 12, through the linkage of the connecting component 40, the materials are always... Maintaining rotation in the same direction, the rotation generates continuous shearing and crushing force on the material, breaking down the fruit and vegetable particles into finer pieces and preventing them from agglomerating. The second auger 13 revolves synchronously with the turntable 11, forming axial stirring of the material in the central area of the tank 10. This, combined with the radial sweeping and unidirectional rotation of the first auger 12, improves the uniformity of material mixing. Simultaneously, the scraper 14 revolves with the second auger 13 and, driven by the connecting component 40, moves in coordination with the first auger 12, scraping up the fruit particles at the bottom so that they can smoothly enter the first auger 12 and the second auger 13. After the first auger 12 revolves in coordination with the radial reciprocating movement and unidirectional rotation, and the second auger 13 and scraper 14, the material achieves a uniform and finer effect and is finally discharged through the discharge port 102 at the bottom of the tank 10, completing the homogenized feeding process.
[0026] The drive component 80 drives the turntable 11 to rotate, which in turn enables the first auger 12 to revolve around the center of the turntable 11 via the transmission component 20. During the revolution, the first auger 12 reciprocates along the radial direction of the turntable 11. In conjunction with the coaxial arrangement of the second auger 13, a composite motion trajectory of revolution and radial reciprocating movement is formed. This structure breaks the limitation of the fixed auger motion trajectory in existing devices, allowing the first auger 12 to cover the entire radial area from the center to the edge of the tank 10, avoiding local material accumulation and allowing materials at different locations to fully contact and collide. At the same time, the first auger 12 always rotates in one direction during the reciprocating movement, continuously generating stable shearing and crushing forces, effectively crushing fruit pulp and other particles, preventing particle agglomeration and clumping, improving the homogenization of materials, eliminating the need for additional homogenization equipment, and simplifying the production process.
[0027] As one embodiment, according to the appendix to the specification Figures 2 to 5 It is known that the driving component 80 includes a rotating sleeve 81, which is sleeved on the fixed shaft 32. Its upper end is connected to the top rotating shaft of the tank 10, and its lower end is fixedly connected to the middle of the turntable 11. The third bevel gear 82 is located on one side of the rotating sleeve 81 and rotates under the drive of the motor 83. The third bevel gear 82 meshes with the fourth bevel gear 811 fixed on the rotating sleeve 81. The transmission component 20 includes a transmission box 21, which is fixed on the lower surface of the turntable 11. Its length direction is parallel to the radial direction of the turntable 11. The first rotating shaft 22 is rotatably mounted in the transmission box 21. Its axial direction is parallel to the length direction of the transmission box 21. It is provided with a reciprocating thread section 23. The first rotating shaft 22 rotates under the action of the rotating component 30. The first slider 24 is located in the transmission box 21 and is threadedly connected to the reciprocating thread section 23. The lower surface of the first slider 24 is connected to the upper rotating shaft of the first auger 12. The rotating assembly 30 includes a plurality of first bevel gears 31, which correspond one-to-one with a plurality of first rotating shafts 22. Each first bevel gear 31 is fixedly connected to the corresponding first rotating shaft 22. The fixed shaft 32 is fixedly installed inside the tank body 10. Its upper end is fixedly connected to the top of the tank body 10, and its lower end is connected to the rotating shaft in the middle of the turntable 11 and passes through it to fix a second bevel gear 33. The second bevel gear 33 meshes with the plurality of first bevel gears 31 respectively.
[0028] When the motor 83 is started, the output shaft of the motor 83 drives the third bevel gear 82 to rotate. Since the third bevel gear 82 meshes with the fourth bevel gear 811 fixed on the rotating sleeve 81, the meshing transmission transmits the rotational power of the motor 83 to the rotating sleeve 81. The rotating sleeve 81 is sleeved on the fixed shaft 32, with its upper end connected to the top rotating shaft of the tank 10 and its lower end fixedly connected to the middle of the turntable 11. The upper end of the fixed shaft 32 is fixed to the top of the tank 10 (keeping it stationary). Therefore, the rotating sleeve 81 rotates stably around the fixed shaft 32, thereby driving the turntable 11 to rotate synchronously around the fixed shaft 32 (coaxial with the second auger 13). When the turntable 11 rotates, the transmission box 21 fixed on the lower surface of the turntable 11 revolves synchronously with the turntable 11. The first rotating shaft 22 inside the transmission box 21 obtains rotational power through the rotating assembly 30. Multiple first bevel gears 31 correspond one-to-one with multiple first rotating shafts 22 and are fixedly connected. The second bevel gear 33 (which remains stationary with the fixed shaft 32) fixed after the lower end of the fixed shaft 32 passes through the turntable 11 meshes with multiple first bevel gears 31 respectively. When the turntable 11 drives the transmission box 21, the first rotating shaft 22 and the first bevel gears 31 to revolve around the fixed shaft 32, the stationary second bevel gear 33 drives the first bevel gear 31 to rotate through the meshing action, thereby driving the corresponding first rotating shaft 22 to rotate synchronously inside the transmission box 21. When the first rotating shaft 22 rotates, the reciprocating threaded section 23 on its shaft body forms a threaded engagement with the first slider 24 in the transmission box 21. Since the first slider 24 is embedded in the transmission box 21 (and cannot rotate due to the limitation of the transmission box 21), the rotational motion of the reciprocating threaded section 23 is converted into the reciprocating linear motion of the first slider 24 along the length direction of the transmission box 21 (i.e., the radial direction of the turntable 11). Furthermore, since the lower surface of the first slider 24 is connected to the upper rotating shaft of the first auger 12, the first slider 24 drives the first auger 12 to move synchronously, ultimately realizing the composite motion of the first auger 12 revolving with the turntable 11 while reciprocating along the radial direction of the turntable 11.
[0029] Specifically, the reciprocating thread section 23 includes two thread grooves with the same pitch but opposite directions, connected at both ends by a transition curve.
[0030] As one embodiment, according to the appendix to the specification Figure 2 Appendix Figure 3 Appendix Figure 6 Appendix Figure 7It can be seen that the connecting plate 131 is fixedly connected to the side of the multiple transmission boxes 21 facing the middle of the turntable 11, the upper end of the second auger 13 is fixedly connected to the connecting plate 131, and the multiple scrapers 14 are evenly distributed along the circumference of the second auger 13 with the second auger 13 as the axis. The side of the scraper 14 facing the rotation direction is the inclined surface 141, and the length direction of the scraper 14 is parallel to the length direction of the transmission box 21. The scraper 14 has a hollow cavity with a through groove 142. The length of the through groove 142 is parallel to the length of the scraper 14. The connecting component 40 includes a first rack 41 and a second rack 42, which are disposed opposite each other inside the scraper 14. The first rack 41 and the second rack 42 move up and down alternately under the drive of the driving component 50. The lower end of the first auger 12 passes through the through groove 142 and extends into the scraper 14 between the first rack 41 and the second rack 42. The first gear 43 at the lower end of the first auger 12 meshes alternately with the first rack 41 and the second rack 42. Multiple first guide cylinders 44 are fixedly provided at the upper ends of the first rack 41 and the second rack 42. Multiple first guide shafts 45 are fixedly provided at the top of the scraper 14. The first guide shaft 45 is coaxial with the corresponding first guide cylinder 44 and is slidably connected to the first guide cylinder 44. A first spring (not shown in the figure) is provided between the lower end of the first guide shaft 45 and the lower end of the first guide cylinder 44. The drive assembly 50 includes two first mounting plates 51, which are respectively fixed on the lower surfaces of the first rack 41 and the second rack 42. The lower ends of the two first mounting plates 51 are provided with two first wedge surfaces 52, which are in opposite directions. Two movable plates 53 are correspondingly disposed below the two first mounting plates 51 and can slide along the length direction of the scraper 14. The two second wedge surfaces 54 on the two movable plates 53 are respectively adapted to the two first wedge surfaces 52. The first ends of the two movable plates 53 are connected by a fixing plate 55.
[0031] When the turntable 11 rotates, multiple transmission boxes 21 fixed on the lower surface of the turntable 11 revolve synchronously with the turntable 11. The second auger 13 revolves synchronously around the fixed shaft 32 (its own axis) with the transmission boxes 21 and the turntable 11. The scraper 14 revolves synchronously with the second auger 13, and its inclined surface 141 facing the direction of rotation synchronously passes over the bottom area of the tank 10 during the revolution.
[0032] In the connecting assembly 40, the first rack 41 and the second rack 42 are arranged opposite to each other in the cavity of the scraper 14. The first guide cylinder 44 at the upper end of the rack 41 and the first guide shaft 45 at the top of the scraper 14 are coaxially slidingly engaged, and the first spring between the first guide shaft 45 and the first guide cylinder 44 is in a natural extension and contraction state, so that the first rack 41 and the second rack 42 maintain their initial height positions. When the first auger 12 moves radially back and forth along the turntable 11 with the first slider 24, the lower end of the first auger 12 moves radially along the through groove 142 of the scraper 14, thereby driving the drive assembly 50 to move. During the movement of the first auger 12, it pushes the moving plate 53 to slide along the length direction of the scraper 14. The second wedge-shaped surfaces 54 of the two moving plates 53 slide relative to the first wedge-shaped surfaces 52 of the two first mounting plates 51, respectively. Since the two first wedge surfaces 52 are in opposite directions, they generate opposing lifting and lowering driving forces on the two first mounting plates 51 during the sliding process. This causes the first rack 41 and the second rack 42 to move alternately up and down along the first guide shaft 45 (one rises while the other falls). The first spring also extends and retracts synchronously with the racks as they move up and down, storing energy. When the first rack 41 and the second rack 42 move alternately up and down, they mesh alternately with the first gear 43. Since the first rack 41 and the second rack 42 move in opposite directions and their meshing positions are staggered, the first gear 43 is always subjected to torque in a single direction. This causes the first auger 12 to rotate in the same direction. During the rotation, it continuously shears and crushes the material inside the tank 10. At the same time, it works in conjunction with the scraping action of the scraper 14 to achieve the synergy of material homogenization and residue removal.
[0033] Specifically, a food-grade telescopic sealing sleeve is installed on the outside of the channel 142. The sealing sleeve is made of polyether-polyurethane (PU) material that meets food industry standards, with an embedded elastic steel wire reinforcement structure. Its length direction is consistent with the channel 142. One end of the sealing sleeve is sealed and fixed to the edge of the channel 142 at the top of the scraper 14 by a food-grade bolt, and the other end is tightly fitted to the side wall of the rotating shaft at the lower end of the first auger 12 by a clamp. The sealing sleeve can be telescopically folded in a 3:1 ratio as the first auger 12 moves, which not only ensures full-stroke sealing protection of the channel 142 and prevents materials from entering the interior of the scraper 14 through the channel 142, but also meets the hygiene requirements for food contact materials and prevents the release of harmful substances.
[0034] As one embodiment, according to the appendix to the specification Figure 7 To be continued Figure 9It is known that the first side of the fixed plate 55 is opposite to the impact block 56 at the lower end of the first auger 12. The lower end of the impact block 56 is slidably connected to the bottom of the scraper 14. The upper end of the impact block 56 is connected to the rotating shaft at the lower end of the first auger 12. The second side of the fixed plate 55 is horizontally fixed with a pin 57. The scraper 14 is fixed with a first sleeve 58. The first sleeve 58 is coaxial with the pin 57. The free end of the pin 57 is slidably nested in the first sleeve 58. The second spring 571 on the first end of the first sleeve 58 is connected to the free end of the pin 57. The pin 57 is locked by the locking assembly 60. Locking assembly 60 includes a first insert rod 61, horizontally slidable on a first slide rail 62 inside the scraper 14, perpendicular to the pin 57, with the first end of the first insert rod 61 matching the insertion hole on the pin 57; a sliding plate 63 is disposed inside a second slide rail 64 inside the scraper 14, its length direction parallel to the length direction of the scraper 14, its first end fixedly connected to the second end of the first insert rod 61, the first side of the sliding plate 63 facing the inner wall of the second slide rail 64, a plurality of second guide cylinders 641 horizontally fixed on the first side of the sliding plate 63, and a plurality of second guide shafts 642 provided on the inner wall of the second slide rail 64. The second guide shaft 642 is coaxial with the corresponding second guide cylinder 641. The second guide shaft 642 and the second guide cylinder 641 are slidably connected. A third spring (not shown in the figure) is provided between the free end of the second guide shaft 642 and the inner end of the first guide cylinder 44. The telescopic column 65 is horizontally slidably mounted on the third slide rail (not shown in the figure) inside the scraper 14 at the second end of the two moving plates 53 and is parallel to the first insert rod 61. The first end of the telescopic column 65 is fixedly connected to the second end of the sliding plate 63. The second end of the telescopic column 65 is connected to the telescopic assembly 70 and extends and retracts under the drive of the telescopic assembly 70. The telescopic assembly 70 includes a pressing post 71, which is horizontally slidably disposed inside the scraper 14 at the second end of the two movable plates 53. The pressing post 71 is perpendicular to the telescopic post 65. The first end of the pressing post 71 is opposite to the impact block 56, and the second end of the pressing post 71 extends into the third guide cylinder 72 inside the scraper 14. The third guide cylinder 72 is coaxial with the pressing post 71. A fourth spring (not shown in the figure) is provided between the second end of the pressing post 71 and the end of the third guide cylinder 72. The rotating sleeve 74 is rotatably mounted on... Inside the scraper 14 and coaxial with the pressing column 71, the rotating sleeve 74 is sleeved on the pressing column 71. The guide column 711 on the pressing column 71 is slidably connected to the arc-shaped guide groove 741 on the rotating sleeve 74. When the pressing column 71 extends or retracts, the guide column 711 slides on the arc-shaped guide groove 741, driving the rotating sleeve 74 to rotate during the sliding process. When the rotating sleeve 74 rotates, the eccentric wheel 742 fixed on it is always in contact with the roller 651 on the second end of the telescopic column 65.
[0035] As the first auger 12 moves radially toward the center of the turntable 11 along with the first slider 24, the impact block 56, connected to the lower shaft of the first auger 12, slides synchronously along the bottom of the scraper 14, gradually approaching and contacting the first side of the fixed plate 55. When it contacts the first side of the fixed plate 55, the first gear 43 disengages from the second rack 42. The continuously moving first auger 12 pushes the fixed plate 55 to slide along the length of the scraper 14 via the impact block 56. The fixed plate 55 drives the two moving plates 53 to move synchronously, and at the same time, the first gear 43 disengages from the second rack 42. The pins 57 on both sides are pressed into the first sleeve 58, and the second spring 571 is compressed and stored until the first end of the first insertion rod 61 is inserted into the insertion hole 572. At this time, the first rack 41 and the second rack 42 are aligned one above the other, and the first rack 41 is exactly flush with the first gear 43. Driven by the transmission assembly 20, when the first auger 12 moves radially towards the edge of the turntable 11, the impact block 56 slides in the opposite direction synchronously with the first auger 12, gradually separating from the first side of the fixing plate 55. Subsequently, the first gear 43... The first gear 43 engages with the first rack 41, causing the first auger 12 to rotate and reciprocate. After the first gear 43 disengages from the first rack 41, it moves to the pressing post 71. The first slider 24 compresses the pressing post 71. During the retraction of the pressing post 71, the guide post 711 on its shaft slides along the arc-shaped guide groove 741 on the inner wall of the rotating sleeve 74. Due to the trajectory design of the arc-shaped guide groove 741, the guide post 711 drives the rotating sleeve 74 to rotate around its own axis when it slides. The eccentric wheel 742 fixed on the rotating sleeve 74 rotates synchronously. During the rotation of 742, its wheel surface continuously presses against the roller 651 at the second end of the telescopic column 65, pushing the telescopic column 65 to move along the third slide rail towards the sliding plate 63. The telescopic column 65 drives the sliding plate 63 to compress the third spring. The sliding plate 63 simultaneously drives the first insertion rod 61 to slide along the first slide rail 62, causing the first end of the first insertion rod 61 to disengage from the insertion hole 572 on the pin 57, releasing the lock on the pin 57. At this time, the pin 57 has a tendency to reset under the elastic force of the second spring 571, but it remains compressed due to the linkage restriction of the moving plate 53.
[0036] After the pin 57 is unlocked, the sliding restriction of the fixed plate 55 and the movable plate 53 is released. The second wedge-shaped surface 54 at the upper end of the two movable plates 53 slides relative to the first wedge-shaped surface 52 at the lower end of the first mounting plate 51. Since the two first wedge-shaped surfaces 52 are in opposite directions, they generate opposing lifting and lowering driving forces on the two first mounting plates 51 during the sliding process. This causes the first rack 41 and the second rack 42 to move alternately up and down along the direction of the first guide shaft 45 (one goes up and the other goes down, exactly the opposite of before, and they are exactly alternate when the first rack 41 and the second rack 42 stop moving up and down). The first spring expands and contracts synchronously with the rise and fall of the two racks, storing energy. The second rack 42 is exactly flush with the first gear 43. Subsequently, the first gear 43 meshes with the second rack 42, so that the first auger 12 always rotates in one direction and moves back and forth. Specifically, a blocking plate is provided in front of the first side of the fixing plate 55 at the bottom of the scraper 14, which allows the fixing plate 55 to stop in the appropriate position (the second rack 42 is flush with the first gear 43) when it is disengaged from the impact block 56 and the first insert rod 61.
[0037] This invention provides a homogenizing feeding device for fruit and vegetable beverages. The specific method of use is as follows: The fruit and vegetable materials to be processed are fed into the tank 10 through the feed inlet 101 at the top of the tank 10. The materials fall naturally into the tank 10. The drive unit 80 is activated, which drives the turntable 11 to rotate around its central axis (coaxial with the second auger 13) inside the tank 10. When the turntable 11 rotates, it drives multiple first augers 12 to revolve synchronously around the center of the turntable 11 through the transmission component 20. At the same time, during the revolution, the transmission component 20 converts the rotational motion of the turntable 11 into the reciprocating movement of the first augers 12 along the radial direction of the turntable 11. This allows the first augers 12 to cover the entire area of the tank 10 while simultaneously sweeping radially from the center to the edge of the turntable 11, forming an all-round agitation of the materials inside the tank 10. During the radial reciprocating movement of the first augers 12, through the linkage of the connecting component 40, the materials are always... Maintaining rotation in the same direction, the rotation generates continuous shearing and crushing force on the material, breaking down the fruit and vegetable particles into finer pieces and preventing them from agglomerating. The second auger 13 revolves synchronously with the turntable 11, forming axial stirring of the material in the central area of the tank 10. This, combined with the radial sweeping and unidirectional rotation of the first auger 12, improves the uniformity of material mixing. Simultaneously, the scraper 14 revolves with the second auger 13 and, driven by the connecting component 40, moves in coordination with the first auger 12, scraping up the fruit particles at the bottom so that they can smoothly enter the first auger 12 and the second auger 13. After the first auger 12 revolves in coordination with the radial reciprocating movement and unidirectional rotation, and the second auger 13 and scraper 14, the material achieves a uniform and finer effect and is finally discharged through the discharge port 102 at the bottom of the tank 10, completing the homogenized feeding process.
