Description

Technical Field

[0001] This invention relates to the field of agricultural product processing machinery technology, and more specifically, to a layered unfolding support device for high-temperature steam sterilization of organic white melon seeds. Background Technology

[0002] In the field of intensive processing of organic agricultural products, especially in the production and processing of organic white melon seeds, food safety and quality control are subject to extremely strict inspection standards. Since relevant organic production regulations explicitly prohibit the use of various chemical fumigants for pest control and sterilization, high-temperature steam sterilization has naturally become the most core and primary sterilization method in the industry.

[0003] However, white melon seeds have physical characteristics such as being flat, lightweight, and prone to sticking together when wet. Current steam sterilization equipment mainly suffers from the following technical defects: First, existing conveyor belt sterilizers typically use a single-layer flat material layer for support, resulting in a thick layer to ensure output. This thick layer hinders heat conduction, making it difficult for steam to penetrate and reach the center. This directly leads to an undercooked phenomenon—overcooked surface and incomplete sterilization at the bottom—seriously affecting product quality and food safety. Second, during traditional horizontal conveying, the sunflower seeds, due to their own weight, maintain the same posture (one side up, one side down against the conveyor belt), preventing even heating on both sides. Finally, flat white sunflower seeds soften when wet on a flat conveyor belt, easily adhering tightly to metal surfaces.

[0004] Therefore, it is necessary to propose a layered unfolding support device for high-temperature steam sterilization of organic white melon seeds, so as to at least partially solve the problems existing in the prior art. Summary of the Invention

[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section.

The load-bearing conveyor assemblies of each layer are staggered in the vertical direction, with the discharge end of the upper layer load-bearing conveyor assembly located above the feed end of the lower layer load-bearing conveyor assembly. The conveying assembly has a breathable bearing component with ventilation holes, and the cross-section of the breathable bearing component has a continuous undulating structure. The dispersing component is located between the discharge end of the carrying conveyor component and the inlet end of the next layer carrying conveyor component to disperse the white melon seed material falling between layers.

[0007] Preferably, the undulating structure of the breathable bearing component has a continuous asymmetric sawtooth waveform in cross-section; each wave cycle includes a leeward sidewall and a windward sidewall, and the angle between the leeward sidewall and the horizontal plane is greater than the angle between the windward sidewall and the horizontal plane.

[0008] Preferably, several vent holes are opened on the leeward side wall, and high-temperature steam flows through the vent holes to the top of the vent bearing.

[0009] Preferably, a number of anti-clogging ribs are provided on the inner surface of the windward side wall of the ventilated bearing component; the anti-clogging ribs extend along the conveying direction of the ventilated bearing component to support the white melon seed material and form a steam flow gap between the white melon seed material and the leeward side wall.

[0010] Preferably, the top-level load-bearing conveyor assembly has a feed inlet above its feed end, and a vibrating cloth is installed at the feed inlet; the bottom-level load-bearing conveyor assembly has a discharge outlet below its discharge end.

[0011] Preferably, the dispersion component includes: Support frame one is connected to the side wall of the main body of the device, and a drive motor is installed at the bottom end; The transmission arm assembly is movably mounted on the support frame. One end of the transmission arm assembly is connected to the output shaft of the drive motor, and the other end extends above the feed end of the next layer of the conveying assembly. The drive motor is configured to drive the transmission arm assembly to swing back and forth. A dispersing plate is connected to the bottom of the transmission arm assembly, and the dispersing plate has an arc-shaped material-bearing surface for accommodating white melon seed material.

[0012] Preferably, the transmission arm assembly includes: The spherical base is connected to the main body of the device via support frame two; A spherical joint, rotatably connected to a spherical seat; The rocker arm is connected to the output shaft of the drive motor via a rotating shaft; The slide rod is hinged at one end to the rocker arm and connected to the dispersion plate at the other end. The slide rod passes through the central hole of the ball joint and is slidably connected to it.

[0013] Preferably, a linkage plate is slidably provided inside the rocker arm, and a pin sleeve is provided at the top of the linkage plate. The slide rod is installed in the pin sleeve through a pin shaft, and the pin shaft is slidably connected to the top slide groove of the rocker arm.

[0014] Preferably, guide rod one and guide rod two are respectively arranged vertically on both sides of the linkage plate; the axis of guide rod one is consistent with the axis of the rotating shaft, and the side of the rocker arm is provided with a guide groove for guide rod one to slide; guide rod two is connected to the bottom end of the linkage plate, the top of guide rod two is slidably connected to the lug on the side of the rocker arm, and a spring is sleeved on guide rod two, and the spring abuts against the bottom of the rocker arm and the lug.

[0015] Preferably, a profile cam is provided on the support frame, and a pointed tip is provided on the side of the profile cam near the receiving material; the profile cam is hollow and forms a cam-shaped limiting edge, and the rotating shaft passes through the center of the profile cam; an I-shaped section is provided on the guide rod, and the I-shaped section is engaged with the limiting edge and slidably connected with the profile cam.

[0016] Compared to existing technologies, this invention provides a layered unfolding support device for high-temperature steam sterilization of organic white melon seeds, which offers at least the following advantages: The linkage between the vertical multi-layered staggered structure and the dispersing components changes the single-layer direct-push conveying method. The undulating, breathable support components use physical geometry to support the white melon seeds, reducing the contact area between the material and the support surface and reserving flow space for the steam at the bottom to penetrate upwards. The dispersing components set between the layers disperse the white melon seeds during the layer-by-layer drop and transfer process, causing the seeds to flip during the fall, exposing the side that was originally in contact with the support surface. This structural linkage ensures that both sides of each white melon seed can be evenly heated by high-temperature steam during the multi-layer alternating conveying, eliminating dead corners in material accumulation and solving the problem of undercooked seeds caused by continuous heating on one side. At the same time, the multi-layered stacked vertical structure concentrates the long conveying path within the main body of the device, allowing steam to penetrate layer by layer from bottom to top within the closed chamber, improving the utilization rate of thermal energy.

[0017] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0021] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0022] Example 1: As Figures 1-3 As shown, the present invention provides a layered unfolding support device for high-temperature steam sterilization of organic white melon seeds, comprising: The main body of the device 1 is connected to the high-temperature steam supply equipment; The multi-layer load-bearing conveyor assembly 2 is horizontally arranged inside the main body 1 of the device. The load-bearing conveyor assemblies 2 of each layer are staggered in the vertical direction, and the discharge end of the upper layer load-bearing conveyor assembly 2 is located above the feed end of the lower layer load-bearing conveyor assembly 2. The carrying and conveying assembly 2 has a breathable bearing component 21, on which a ventilating hole 22 is provided, and the cross-section of the breathable bearing component 21 has a continuous undulating structure. The dispersing component 3 is located between the discharge end of the carrying conveying component 2 and the inlet end of the next layer carrying conveying component 2, and is used to disperse the white melon seed material falling between layers.

[0023] The top-level load-bearing conveyor assembly 2 has a feed inlet 4 above its feed end, and a vibrating cloth 5 is installed at the feed inlet 4; the bottom-level load-bearing conveyor assembly 2 has a discharge outlet 6 below its discharge end.

[0024] The working principle and beneficial effects of the above technical solution are as follows: This embodiment provides a layered unfolding support device for high-temperature steam sterilization of organic white melon seeds. An external high-temperature steam supply device delivers high-temperature steam to the main body 1 of the device via pipelines. The white melon seeds enter the device through the feed inlet 4 at the top of the main body 1. A vibrating distributor 5 located at the feed inlet 4 is activated, generating a directional vibration force that directly acts on the white melon seeds below the feed inlet 4, dispersing any clumps and spreading them evenly onto the breathable support member 21 of the first layer of the conveying assembly 2.

[0025] The conveying assembly 2 is driven by sprockets. A permeable carrier component 21 surrounds the left and right sprockets. The sprockets drive the permeable carrier component 21, causing it to move horizontally forward and convey the melon seeds. The cross-section of the permeable carrier component 21 has a continuous undulating structure, supporting the flat-laid melon seeds at the crests or troughs. High-temperature steam inside the main body 1 flows upward, passing through the steam vents 22 on the permeable carrier component 21, contacting and heating the supported melon seeds above it.

[0026] As the ventilated support component 21 continues to operate, when the melon seeds are conveyed to the discharge end of the first-layer support conveying assembly 2, they lose the bottom support of the ventilated support component 21 and fall downwards under the influence of gravity. During their fall, the melon seeds collide with the dispersing component 3 located between the two layers of support conveying assemblies 2. The dispersing component 3 blocks and disperses the falling melon seeds, forcibly diverting slightly sticky seeds and causing them to flip during their descent. The dispersed and flipped melon seeds fall into the feed end of the second-layer support conveying assembly 2, which then conveys them horizontally in the opposite direction.

[0027] The main body 1 of the device is equipped with a multi-layer bearing and conveying assembly 2, which is arranged in a staggered "Z" shape. The white melon seeds are repeatedly conveyed horizontally, heated, and fall and tumble between layers in the main body 1, and finally discharged from the bottom discharge end.

[0028] Through the above structural design, the linkage between the vertical multi-layer staggered architecture and the dispersed components changes the material conveying method of single-layer direct pushing. The undulating, breathable bearing component 21 uses its physical geometry to support the white melon seeds, reducing the contact area between the material and the bearing surface, and reserving flow space for the steam at the bottom to penetrate upwards. The dispersed components set between the layers disperse the white melon seeds during the layer-by-layer falling and handover process, and the white melon seeds flip during the fall, exposing the side that was originally in contact with the bearing surface. This structural linkage ensures that both sides of each white melon seed can be evenly heated by high-temperature steam during the multi-layer alternating conveying, eliminating dead corners of material accumulation and solving the problem of undercooked material caused by continuous heating on one side. At the same time, the multi-layer stacked vertical structure concentrates the long conveying path within the main body 1 of the device, and the steam penetrates layer by layer from bottom to top in the closed box, improving the utilization rate of thermal energy.

[0029] Example 2: Based on Example 1 above, the undulating structure of the breathable bearing member 21 has a continuous asymmetric sawtooth waveform in cross-section; each wave cycle includes a leeward sidewall 23 and a windward sidewall 24, and the angle between the leeward sidewall 23 and the horizontal plane is greater than the angle between the windward sidewall 24 and the horizontal plane.

[0030] Several vent holes 22 are provided on the leeward side wall 23, and high-temperature steam flows through the vent holes 22 to the top of the ventilated support member 21.

[0031] The working principle and beneficial effects of the above technical solution are as follows: Flat white melon seeds can easily cover and block the steam vents below on a regular flat or symmetrical corrugated plate, thus blocking the upward flow path of steam.

[0032] In this embodiment, the cross-section of the ventilated support member 21 is processed into a continuous asymmetric sawtooth waveform. Each cycle includes a steeply sloped leeward sidewall 23 and a gently sloped windward sidewall 24. After the melon seeds fall into this asymmetric structure, under the pull of the downward component of gravity, the melon seeds cannot stay on the steep leeward sidewall 23 and will inevitably slide down the slope, eventually concentrating on the slope or trough of the windward sidewall 24 with a smaller inclination angle. When the high-temperature steam supplied from bottom to top inside the main body 1 flows to the area below the ventilated support member 21, since the steam vents 22 are only opened on the steep leeward sidewall 23, and the melon seeds are concentrated on the windward sidewall 24, the steam flow directly sprays out in large quantities from the steam vents 22 of the leeward sidewall 23, which is not blocked by any material, and enters the space above the ventilated support member 21.

[0033] Through the above structural design, the slope difference of the asymmetrical inclined plane and the material's own gravity sliding characteristics are used to physically isolate the scattered material. This structure forcibly guides the white melon seeds to avoid the leeward sidewall where the steam vents are located, eliminating physical interference from direct overlap between flat materials and the steam vents. This structural intervention ensures the absolute unobstructed flow of steam injection channels, avoiding problems such as local steam short circuits and heat overload in adjacent areas caused by the blockage of individual holes.

[0034] Example 3: Based on Example 2 above, a number of anti-blocking ribs 25 are provided on the inner surface of the windward sidewall 24 of the breathable bearing member 21; the anti-blocking ribs 25 extend along the conveying direction of the breathable bearing member 21 to support the white melon seed material and form a steam flow gap between the white melon seed material and the leeward sidewall 23.

[0035] The working principle and beneficial effects of the above technical solution are as follows: The damp bottom of the melon seeds adhered tightly to the supporting metal plate over a large area, causing moisture to accumulate and become trapped, resulting in water stains and sticking to the bottom surface.

[0036] In this embodiment, raised anti-clogging ribs 25 are arranged on the inner surface of the windward sidewall 24. When the melon seed slides down under the guidance of gravity and stops on the windward sidewall 24, the bottom surface of the melon seed is abutted and physically supported by the spaced anti-clogging ribs 25. The bottom surface of the melon seed is no longer in direct contact with the flat metal surface of the windward sidewall 24, and a small physical gap is forcibly created between the two.

[0037] Due to the steep inclination angle of the leeward sidewall 23, the high-speed steam jet ejected from the steam vent 22 is angled towards the opposite windward sidewall 24. Upon contacting the edge of the gap formed between the anti-blocking rib 25 and the melon seed, the airflow is deflected by the physical boundary, penetrating the gap while closely adhering to the metal surface of the windward sidewall 24. The high-speed steam flow then sweeps laterally across the bottom surface of the melon seed, finally overflowing from both sides and rising upwards.

[0038] Through the above structural design, the anti-clogging rib 25 creates a forced, microscopic physical gap between the bearing surface and the material. Combined with the specific steam jet deflection angle brought about by the asymmetrical structure, the originally vertically rising high-temperature steam is guided into a sweeping airflow flowing laterally along the metal surface. This lateral airflow directly washes over the bottom of the melon seeds, carrying away the condensed water molecules accumulated at the bottom of the material, cutting off the physical conditions for water stains to form. Under the dynamic pressure support formed by the lateral steam sweeping, the water vapor adsorption force between the bottom surface of the melon seeds and the metal plate is greatly weakened, ensuring that the melon seeds can cleanly and neatly detach from the bearing surface when they are turned over and dumped at the discharge end, preventing adhesion and sticking to the wall.

[0039] Example 4: Figures 4-7 As shown, based on the above embodiment 1, the dispersion component 3 includes: Support frame 31 is connected to the side wall of the main body 1 of the device, and a drive motor 32 is installed at the bottom end; The transmission arm assembly is movably mounted on the support frame 31. One end of the transmission arm assembly is connected to the output shaft of the drive motor 32, and the other end extends to the feed end of the next layer of the conveying assembly 2. The drive motor 32 is configured to drive the transmission arm assembly to swing back and forth. The dispersing plate 33 is connected to the bottom end of the transmission arm assembly, and the dispersing plate 33 has an arc-shaped material-bearing surface for accommodating the white melon seed material.

[0040] The drive arm assembly includes: The spherical seat 34 is connected to the main body 1 of the device via the second support frame 35; The ball joint 36 is rotatably connected to the ball seat 34; The rocker arm 37 is connected to the output shaft of the drive motor 32 via the rotating shaft 30; The slide rod 38 is hinged at one end to the rocker arm 37 and connected to the dispersion plate 33 at the other end. The slide rod 38 passes through the central hole of the ball joint 36 and is slidably connected to it.

[0041] The working principle and beneficial effects of the above technical solution are as follows: The drive motor 32, connected to the bottom of the support frame 31, is energized and operates, outputting rotational power outwards. The output shaft drives the rotating shaft 30 connected to it to rotate, which in turn drives the rocker arm 37 to rotate in a horizontal circle. One end of the rocker arm 37 is hinged to the top of the slide rod 38, and the rotation of the rocker arm 37 causes the top of the slide rod 38 to revolve around the axis of the rotating shaft 30. The slide rod 38 extends downwards and passes through the through hole in the middle of the ball joint 36. The ball joint 36 is rotatably mounted inside the ball seat 34, which is fixed to the main body 1 of the device by the support frame 35.

[0042] As the top of the slide bar 38 revolves, it slides back and forth within the through hole of the ball joint 36 due to the ball joint 36 limiting its middle section. Simultaneously, the ball joint 36 deflects at multiple angles within the ball seat 34 to accommodate the changes in the slide bar 38's posture during rotation. The bottom end of the slide bar 38, extending out of the ball joint 36, enters the falling space between the upper discharge end and the lower feed end. Under these multiple constraints, the dispersing plate 33 at the bottom of the slide bar 38 forms a three-dimensional sweeping trajectory of an inverted cone within the falling space. The white melon seeds falling from the upper layer of the conveying assembly 2 come into contact with the high-speed sweeping dispersing plate 33 in mid-air. The arc-shaped bearing surface of the dispersing plate 33 applies an oblique tangential thrust to the falling white melon seeds, breaking up any sticky seeds and scattering the dispersed seeds outwards onto the feed end of the lower layer of the conveying assembly 2.

[0043] Through the above structural design, the rotational motion of the drive motor 32 is transformed into a composite sweeping motion of the dispersing plate 33 in three-dimensional space by the linkage of the rocker arm 37, the slide bar 38, and the ball joint 36. The ball joint 36, acting as a fixed universal fulcrum, not only allows the dispersing plate 33 to sweep horizontally but also provides axial extension and retraction in the vertical direction during the sweeping process. When the arc-shaped material-bearing surface of the dispersing plate 33 contacts the falling material, it forms a lateral cutting angle, rather than a rigid vertical impact. This mechanical linkage provides sufficient kinetic energy to break the adhesion between the wet materials while protecting the integrity of the melon seed shells and significantly expanding the spreading and coverage area of ​​the material on the next layer of bearing surface.

[0044] Example 5: Based on Example 4 above, a linkage plate 39 is slidably arranged inside the rocker arm 37, and a pin sleeve is provided at the top of the linkage plate 39. The slide rod 38 is installed in the pin sleeve through the pin shaft 41, and the pin shaft 41 is slidably connected to the top slide groove of the rocker arm 37.

[0045] The linkage plate 39 is provided with vertically arranged guide rod 42 and guide rod 43 on both sides respectively; the axis of guide rod 42 is consistent with the axis of the rotating shaft 30, and the rocker arm 37 is provided with a guide groove 44 for the guide rod 42 to slide; the guide rod 43 is connected to the bottom end of the linkage plate 39, the top of the guide rod 43 is slidably connected to the lug 47 on the side of the rocker arm 37, and a spring 45 is sleeved on the guide rod 43, and the spring 45 abuts against the bottom of the rocker arm 37 and the lug 47.

[0046] A profile cam 46 is provided on the support frame 31. The profile cam 46 has a pointed tip on the side near the receiving material. The profile cam 46 is hollow and forms a cam-shaped limiting edge. The rotating shaft 30 passes through the center of the profile cam 46. A guide rod 42 is provided with an I-shaped section, which is engaged with the limiting edge and slidably connected to the profile cam 46.

[0047] The working principle and beneficial effects of the above technical solution are as follows: Figure 7 The diagram shows the motion trajectory of the dispersion plate 33, where A1, B1, and C1 are the positions of the endpoints of the dispersion plate in each stage, and A2, B2, and C2 are the positions of the midpoints of the dispersion plate in each stage.

[0048] The drive motor 32 drives the rocker arm 37 to rotate at a constant speed in a circular motion, and the linkage plate 39 rotates accordingly. When the rocker arm 37 is rotating to the receiving side where a large number of white melon seeds are falling, the I-shaped section on the guide rod 42 is exactly located within the circular area of ​​the contour cam 46. At this time, the spring 45 pulls the linkage plate 39, so that the pin 41 at the top of the slide rod 38 is in a position close to the rotating shaft 30. The slide rod 38 maintains a specific tilt state under the limitation of the ball joint 36 in the middle section, and the dispersion plate 33 at the bottom sweeps the falling material normally.

[0049] As the rocker arm 37 continues to rotate and gradually moves away from the receiving side, the I-shaped section moves outward along the edge of the contour cam 46 towards its convex tip. The gradually increasing radius of the cam forcefully pushes the guide rod 42 outward, forcing the linkage plate 39 to overcome the tension of the spring 45 and slide outward along the rocker arm 37. The spring 45 is compressed and stores mechanical potential energy. During this sliding process, the pin 41 moves with the linkage plate 39, and under the leverage of the ball joint 36, the trajectory of the dispersion plate 33 at the bottom of the slide rod 38 gradually contracts inward.

[0050] As the rocker arm 37 rotates until the I-shaped section passes the tip of the contour cam 46, the cam edge trajectory suddenly contracts inward and returns to the radius of the circular area. In the instant the outward pushing force of the cam edge is lost, the spring 45 violently releases its accumulated potential energy, instantly pulling the linkage plate 39 back to its original position. This sudden return causes the pin 41 to rapidly contract inward, and with the leverage of the ball joint 36, the bottom dispersion plate 33 instantly swings back towards the receiving side at extremely high linear velocity, completing an explosive sweeping motion the moment it cuts into the material waterfall.

[0051] Through the above structural design, the geometric trajectory guidance of the contour cam 46 is integrated with the instantaneous potential energy release action of the spring 45. Without changing the uniform rotation setting of the motor, the motion trajectory and speed curve of the dispersing plate 33 are reconstructed within a purely mechanical frame. During the no-load return phase as the mechanism gradually moves away from the material receiving side, the cam pushes the dispersing plate 33 to contract its trajectory, leaving sufficient space to avoid unnecessary frictional interference between the rotating parts and the inner wall of the device body. When the mechanism reaches the critical point where the material falls densely on the receiving side, the sudden release of the spring's potential energy is triggered by the tip falling, instantly superimposing an extremely fast trajectory change acceleration swing on the dispersing plate 33. This sudden return action injects a huge instantaneous impulse directly into the interior of the surface-adhesive material clumps. The strong mechanical misalignment shear force directly disintegrates the adsorption structure between the wet particles, causing the clumps to completely break up and disaggregate in mid-air.
