Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to an environmentally friendly sterilization device for producing snow-white melon seed kernels. Background Technology

[0002] Snow-white melon seeds are kernels made from the shelled seeds of cucurbitaceous crops such as squash and zucchini. They are characterized by their pure white color, large size, and abundant kernels, and are rich in protein, fatty acids, and various trace elements. Sterilization is a key process in the processing of snow-white melon seeds, effectively killing microorganisms both inside and outside the material, ensuring food safety, and extending the product's shelf life. Currently, the mainstream sterilization methods for melon seeds include ultraviolet light, microwave, moist heat, and high-temperature drying.

[0003] A common problem with current sterilization equipment is the inability of materials to be distributed in a single layer during discharge. Existing discharge mechanisms often employ vibrating screens or conveyor belts for direct transport, lacking dedicated dispersing and guiding components. As a result, sunflower seeds are prone to piling and agglomeration due to gravity and friction. Furthermore, the lack of a dynamic matching mechanism between the equipment's conveying speed and the upstream material flow rate leads to localized material accumulation on the conveying surface when the flow rate fluctuates.

[0004] Multi-layer stacking of materials can lead to uneven sterilization. The kernels in the lower layers and covered areas of the stack cannot fully contact the sterilization sources such as ultraviolet light, microwaves, and hot air, resulting in significant differences in sterilization dosage within the same batch of products. On the one hand, some kernels are not thoroughly sterilized, resulting in excessive microbial residues and posing food safety risks. On the other hand, some materials suffer heat damage due to excessively high local energy density, causing the snow-white kernels to turn yellow, damaging their original appearance and significantly reducing their commercial value. Therefore, there is an urgent need to develop a sterilization device that can achieve a single-layer distribution of kernel output, thereby improving sterilization uniformity and ensuring consistent and stable product quality. Summary of the Invention

[0005] Given that existing sunflower seed kernel sterilization equipment cannot achieve single-layer material conveying, which easily leads to material stacking, uneven sterilization, food safety hazards, and damage to product appearance and reduced commodity value, an environmentally friendly sterilization device for producing snow-white sunflower seeds is proposed.

[0006] The purpose is that when sunflower seeds move on the obtuse-angled triangular conveyor belt, the vibrating roller and vibrating plate work together to transmit vibration to the top plane and the side slope of the conveyor belt, causing the sunflower seeds to initially flatten on the top surface of the conveyor belt, and then bounce on the slope of the conveyor belt, so that the sunflower seeds form multiple dispersed accumulation areas on the conveyor belt, effectively reducing the probability of sunflower seed accumulation and improving the sterilization effect of sunflower seeds.

[0007] The technical solution of this invention is an environmentally friendly sterilization device for producing snow-white melon seed kernels, including a sterilization device and a hopper. The hopper is located above the conveyor end of the sterilization device, and a base is located below the hopper. A conveyor belt is installed inside the base, and a drive roller, a vibrating roller, and an adjusting roller are installed inside the conveyor belt. The drive roller, vibrating roller, and adjusting roller cooperate to support the conveyor belt and form an obtuse-angled triangular structure. The upper plane of the conveyor belt slides in contact with the bottom surface of the hopper. One inclined surface of the conveyor belt is located above the conveyor belt of the sterilization device. A motor is installed on one side of the base, and the motor drives the drive roller and the vibrating roller to rotate synchronously. The vibrating roller has a hollow structure. A fixed rod is provided at the center of the vibrating roller shaft. The end of the fixed rod extends through the vibrating roller to the outside and is connected and fixed to the outer wall of the base. Multiple arc-shaped blocks are fixedly arranged axially at equal intervals on the fixed rod. Multiple fixed boxes are arranged in a ring at equal intervals between the fixed rod and the inner cavity of the vibrating roller. The fixed boxes rotate synchronously with the vibrating roller. Multiple vibrating plates are slidably connected inside the fixed boxes. An elastic element is connected between the vibrating plates and the fixed boxes. The inner arc surface of the arc-shaped blocks slides in contact with the corresponding vibrating plates. Multiple through holes are opened in a ring at equal intervals on the vibrating roller. The vibrating plates are arranged corresponding to the through holes.

[0008] Furthermore, an adjusting plate is vertically slidably connected to the side wall of the hopper outlet, and the lower end of the adjusting plate is serrated.

[0009] Furthermore, both the drive roller and the vibrating roller are rotatably connected to the side wall of the base, the motor is fixedly installed on the side wall of the base, the output shaft of the motor is drivenly connected to one end of the drive roller, and a chain is connected between the drive roller and the vibrating roller.

[0010] Furthermore, the vibrating roller includes a rotating drum, both ends of which are fixedly connected to end caps. The end caps are rotatably connected to the base. A fixing rod is movably inserted through the end caps, and a fixing frame is fixedly connected to the end of the fixing rod. The fixing frame is fixedly connected to the side wall of the base.

[0011] Furthermore, the vibrating plate has a T-shaped structure, and a groove is provided on the side of the vibrating plate facing the fixed rod. A sliding rod is fixed on the inner wall of the groove, and the inner arc surface of the arc block slides in contact with the corresponding sliding rod; multiple arc blocks are symmetrically distributed in a stepped manner along the axial direction on the outer circumference of the fixed rod.

[0012] Furthermore, both ends of the adjusting roller are rotatably connected to sliders, and the sliders slide in a groove on the base; the end cap extends movably through to the outside of the base and is fixedly connected to a sector-shaped gear ring, a gear one is provided below the sector-shaped gear ring, and a gear two is meshed between the gear one and the sector-shaped gear ring, both gear one and gear two are rotatably connected to the side wall of the base, a rack is meshed below the gears, one end of the rack is rotatably connected to the end of the adjusting roller, and the other end of the rack is connected to the side wall of the base via an elastic element two.

[0013] Furthermore, the bottom surface of the conveyor belt has a tension roller in rolling contact with it, and both ends of the tension roller are rotatably connected to connecting rods. The other end of the connecting rod is rotatably connected to the inner wall of the base, and the connecting rod and the inner wall of the base are connected together by an elastic element.

[0014] Furthermore, the material conveying speed of the conveyor belt is lower than the conveying speed of the drive belt of the sterilization equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By using a combination of drive rollers, vibrating rollers, and adjusting rollers, the conveyor belt forms an obtuse-angled triangular distribution. At the same time, the vibrating rollers and vibrating plates work together to transmit high-frequency vibrations to the top surface of the conveyor belt and to impact the inclined surface of the conveyor belt. This allows the sunflower seed kernels to be initially spread on the top surface and then tossed and dispersed, effectively improving the uniformity of material dispersion. Meanwhile, the adjusting rollers dynamically change the drop position of the material, ensuring that the material is evenly distributed on the conveyor belt and avoiding accumulation, thus improving the sterilization effect and product quality.

[0016] 2. Multiple arc-shaped blocks are distributed in an axial stepped manner along the outer periphery of the fixed rod, increasing the vibration frequency and further improving the dispersion of sunflower seed kernels on the top surface of the conveyor belt. At the same time, the vibrating plates in the same fixed box alternately impact the conveyor belt, increasing the impact range and making the sunflower seed kernels bounce more widely and dispersed on the inclined surface of the conveyor belt, further improving the dispersion effect of the material.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1, referring to Figures 1-10 This invention provides an environmentally friendly sterilization device for producing white melon seed kernels, comprising a sterilization device 1 and a hopper 2, the hopper 2 being positioned above the conveying end of the sterilization device 1. The sterilization device 1 is used to sterilize the white melon seed kernels, employing conventional sterilization technologies such as ultraviolet sterilization or microwave sterilization. The hopper 2, positioned above the conveying end of the sterilization device 1, is used to store the white melon seed kernel material to be sterilized.

[0021] Reference Figure 2 , Figure 4The system also includes a base 4 located below the hopper 2. A conveyor belt 5 is installed inside the base 4, and a drive roller 6, a vibrating roller 7, and an adjusting roller 8 are installed inside the conveyor belt 5. The drive roller 6, vibrating roller 7, and adjusting roller 8 cooperate to support the conveyor belt 5, forming an obtuse-angled triangular structure. The base 4 is a hollow box structure used to install and support the various transmission components. The conveyor belt 5 is a ring-shaped flexible belt used to transport the white melon seed kernels from the hopper 2 to the conveyor belt of the sterilization equipment 1. The drive roller 6 is located inside the base 4 on one side away from the conveying end of the sterilization equipment 1. The vibrating roller 7 is located between the drive roller 6 and the conveying end of the sterilization equipment 1, and the vibrating roller 7 is horizontally positioned relative to the drive roller 6. The adjusting roller 8 is located below the vibrating roller 7 and the conveying end of the sterilization equipment 1. The drive roller 6, vibrating roller 7, and adjusting roller 8 are distributed in an obtuse-angled triangle, with the interior angle of the triangle located at the vibrating roller 7 being an obtuse angle.

[0022] Reference Figure 4 The upper surface of the conveyor belt 5 slides in contact with the bottom surface of the hopper 2. One inclined surface of the conveyor belt 5 is positioned above the conveyor belt of the sterilization equipment 1. A motor 9 is installed on one side of the base 4, which drives the drive roller 6 and the vibrating roller 7 to rotate synchronously. The motor 9 drives the drive roller 6 and the vibrating roller 7 to rotate synchronously, and the conveyor belt 5 and the transmission belt of the sterilization equipment 1 maintain the same direction of rotation. The bottom surface of the discharge port of the hopper 2 is in contact with the top surface of the conveyor belt 5. When the conveyor belt 5 moves, the snow-white melon seed kernel material falls onto the surface of the conveyor belt 5 under the action of gravity, and is carried out of the discharge port of the hopper 2 by the moving conveyor belt 5. After passing the top surface and the right inclined surface of the conveyor belt 5, it finally falls onto the transmission belt of the sterilization equipment 1.

[0023] Reference Figure 2 , Figure 5 , Figure 7 The vibrating roller 7 has a hollow structure, and a fixing rod 10 is set at the center of the vibrating roller 7. The end of the fixing rod 10 extends through the vibrating roller 7 to the outside and is connected and fixed to the outer wall of the base 4. Multiple arc-shaped blocks 11 are fixedly fixed on the fixing rod 10 at equal intervals along the axis. The end of the fixing rod 10 is connected and fixed to the side wall of the base 4 by a fixing frame, thereby fixing the fixing rod 10 relative to the base 4. When the vibrating roller 7 rotates, the fixing rod 10 remains stationary. The arc-shaped block 11 has a slightly curved cross-section, with its inner arc surface facing the axis of the fixing rod 10, and is set above the fixing rod 10.

[0024] Reference Figures 6-8Multiple fixed boxes 12 are arranged in a ring at equal intervals between the fixed rod 10 and the inner cavity of the vibrating roller 7. The fixed boxes 12 rotate synchronously with the vibrating roller 7. Multiple vibrating plates 13 are slidably connected inside the fixed boxes 12. An elastic element 14 is connected between the vibrating plates 13 and the fixed boxes 12. The inner arc surface of the arc block 11 slides in contact with the corresponding vibrating plate 13. Multiple through holes 73 are opened in a ring at equal intervals on the vibrating roller 7. The vibrating plates 13 are correspondingly arranged with the through holes 73. The fixed box 12 is a rectangular box-shaped structure that extends radially along the vibrating roller 7. The end of the fixed box 12 is connected and fixed to the inner wall of the vibrating roller 7. The fixed box 12 rotates synchronously with the vibrating roller 7. The elastic element 14 is preferably a compression spring. Its two ends are connected to the vibrating plate 13 and the fixed box 12, respectively. When the vibrating plate 13 is not in contact with the arc block 11, the elastic element 14 drives the vibrating plate 13 to be located inside the vibrating roller 7.

[0025] Specifically, the conveyor belt 5 drives the material in the hopper 2 to move onto the conveyor belt of the sterilization equipment 1. The vibrating roller 7 drives the fixed box 12 and the internal vibrating plate 13 to rotate synchronously. At the same time, when the vibrating plate 13 contacts the inner arc surface of the arc block 11, it slides towards the fixed rod 10, and drives the elastic element 14 to compress and generate elastic energy. When the vibrating plate 13 stops contacting the arc block 11, the elastic element 14 immediately rebounds. Under the action of the elastic element 14, the vibrating plate 13 can pass through the through hole 73 and protrude from the outer surface of the vibrating roller 7, and impact the right inclined surface of the conveyor belt 5, causing the right inclined surface of the conveyor belt 5 to... The sunflower seed kernels on the surface separate along the moving direction. At the same time, all the vibrating plates 13 cooperate with the arc-shaped blocks 11 in sequence to generate high-frequency vibration, so that the sunflower seed kernels on the top plane of the conveyor belt 5 are initially flattened. This technical solution effectively solves the problem that the white sunflower seed kernels are easy to accumulate and unevenly dispersed on the conveyor belt of the sterilization equipment 1 in the existing sterilization equipment, resulting in incomplete sterilization. It ensures that the material is discharged evenly. With the help of vibration, the material is fully flattened before entering the conveyor belt of the sterilization equipment 1, eliminating sterilization dead corners, greatly improving the uniformity of sterilization effect and production efficiency. Moreover, the overall structure is compact and the operation is reliable.

[0026] Reference Figure 2 An adjusting plate 3 is vertically slidably connected to the side wall of the discharge port of hopper 2, and the lower end of the adjusting plate 3 is serrated.

[0027] Specifically, the adjusting plate 3 can slide up and down along the side wall of the discharge port of the hopper 2 to adjust the height of the discharge port, thereby controlling the discharge thickness of the snow-white melon seed kernels. The serrated structure at the lower end of the adjusting plate 3 allows the material to form multiple parallel piles on the conveyor belt 5, thereby reducing the formation of a thick planar pile when the material enters the conveyor belt 5 from the hopper 2. Under subsequent vibration, the multiple parallel piles of material spread out in a direction perpendicular to the material's direction of travel, reducing the pile thickness.

[0028] Among them, reference Figure 3The adjusting plate 3 includes an L-shaped plate that is vertically slidably connected to the side wall of the hopper 2, and multiple material distribution plates set at the bottom of the L-shaped plate. The material distribution plates have a trapezoidal structure and are connected to the L-shaped plate by bolts and wing bolts to adjust the width spacing. Two elongated holes are vertically opened on the L-shaped plate, and bolts that are threadedly connected to the hopper 2 are set in the holes. Tightening or loosening the bolts can adjust the height of the L-shaped plate.

[0029] Reference Figure 4 Both the drive roller 6 and the vibrating roller 7 are rotatably connected to the side wall of the base 4. The motor 9 is fixedly installed on the side wall of the base 4. The output shaft of the motor 9 is connected to one end of the drive roller 6 for transmission. The drive roller 6 and the vibrating roller 7 are connected together by a chain.

[0030] Specifically, the output shaft of motor 9 is connected to one end of the drive roller 6, and motor 9 drives drive roller 6 to rotate. The direction of rotation is the same as the direction of rotation of the transmission belt of sterilization equipment 1. Furthermore, a chain is connected between drive roller 6 and vibrating roller 7 to achieve synchronous rotation.

[0031] Reference Figure 2 , Figure 5 , Figure 6 The vibrating roller 7 includes a rotating drum 71, with end caps 72 fixedly connected to both ends of the rotating drum 71. The end caps 72 are rotatably connected to the base 4. A fixing rod 10 is movably inserted through the end cap 72, and a fixing frame is fixedly connected to the end of the fixing rod 10. The fixing frame is fixedly connected to the side wall of the base 4.

[0032] Specifically, the rotating cylinder 71 is a cylindrical structure with openings at both ends. The rotating cylinder 71 has multiple through holes 73 axially. Both ends of the rotating cylinder 71 are fixedly connected to end caps 72 by bolts. The end caps 72 are rotatably connected to the side wall of the base 4, thereby forming a closed cavity structure.

[0033] Reference Figures 6-10 The vibrating plate 13 has a T-shaped structure. A groove is provided on the side of the vibrating plate 13 facing the fixed rod 10. A sliding rod 18 is fixed on the inner wall of the groove. The inner arc surface of the arc block 11 slides in contact with the corresponding sliding rod 18. Multiple arc blocks 11 are symmetrically distributed in a stepped manner along the axial direction on the outer circumference of the fixed rod 10.

[0034] Specifically, the vibrating plate 13 rotates synchronously with the fixed box 12. When the sliding rod 18 contacts the inclined surface of the arc block 11, it drives the vibrating plate 13 to move towards the fixed rod 10 inside the fixed box 12 and compresses the elastic element 14. After the sliding rod 18 slides along the inner arc surface of the arc block 11 and leaves, the elastic element 14 releases its elastic force, causing the vibrating plate 13 to pass through the corresponding through hole 73 and hit the right inclined surface of the conveyor belt 5, causing the sunflower seed kernel material to bounce on the inclined surface, so that the material forms a multi-segment distribution on the conveyor belt 5, improving the dispersion of the material and avoiding accumulation.

[0035] The multiple arc-shaped blocks 11 are arranged in a stepped manner, which allows the contact time between the vibrating plate 13 and the corresponding arc-shaped block 11 in the same fixed box 12 to be different. This causes the vibrating plate 13 in the same fixed box 12 to impact the conveyor belt 5 in multiple times, further improving the dispersion of the material and increasing the vibration frequency, thereby improving the dispersion effect of the sunflower seed kernel material on the top plane of the conveyor belt 5.

[0036] Example 2, refer to Figure 11 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: both ends of the adjusting roller 8 are rotatably connected to sliders 19, and the sliders 19 slide in a groove on the base 4; the end cover 72 extends through to the outside of the base 4 and is fixedly connected to a sector-shaped gear ring 15, a gear 16 is provided below the sector-shaped gear ring 15, and a gear 24 is meshed between the gear 16 and the sector-shaped gear ring 15. Both the gear 16 and the gear 24 are rotatably connected to the side wall of the base 4. A rack 17 is meshed with the lower side of the gear 16, one end of the rack 17 is rotatably connected to the end of the adjusting roller 8, and the other end of the rack 17 is connected to the side wall of the base 4 with an elastic element 20.

[0037] Specifically, the sector-shaped gear ring 15 is an arc-shaped gear ring. The sector-shaped gear ring 15 rotates synchronously with the vibrating roller 7. When the sector-shaped gear ring 15 meshes with gear 24, it drives gear 16 to rotate. The rack 17 drives the adjusting roller 8 to move towards the side closer to the hopper 2, realizing real-time dynamic change of the drop point of the sunflower seed kernels, further avoiding the accumulation of sunflower seed kernels on the conveyor belt. The elastic element 20 preferably adopts a tension spring. When gear 16 drives rack 17 to move, elastic element 20 stretches and stores force. When the sector-shaped gear ring 15 is not meshed with gear 24, elastic element 20 shortens and drives rack 17 and adjusting roller 8 to reset.

[0038] Reference Figure 4 , Figure 12 The bottom surface of the conveyor belt 5 has a tension roller 21 in rolling contact. Both ends of the tension roller 21 are rotatably connected to a connecting rod 22. The other end of the connecting rod 22 is rotatably connected to the inner wall of the base 4. An elastic element 23 is connected between the connecting rod 22 and the inner wall of the base 4.

[0039] Specifically, the elastic element 23 is preferably a tension spring, which applies an elastic force to the connecting rod 22 so that the tension roller 21 always presses against the bottom surface of the conveyor belt 5, maintaining the tension of the conveyor belt 5, so as to ensure that the conveyor belt 5 always maintains effective transmission contact with the drive roller 6, the vibrating roller 7, and the adjusting roller 8 when the adjusting roller 8 is displaced.

[0040] Reference Figure 1 The material conveying speed of conveyor belt 5 is lower than the conveying speed of the drive belt of sterilization equipment 1.

[0041] Specifically, this speed difference allows the snow-white melon seeds to be further dispersed as they are transferred from conveyor belt 5 to the sterilization equipment 1, preventing material accumulation. The rest of the structure is the same as in Example 1.

[0042] Based on embodiments 1-2, the working principle of this invention is as follows: Sunflower seeds are poured into hopper 2, motor 9 and sterilization equipment 1 are started, conveyor belt 5 rotates, driving the material to move. After the sliding rod 18 of vibrating plate 13 contacts the arc-shaped block 11, vibrating plate 13 passes through through hole 73 and impacts conveyor belt 5. Simultaneously, vibrating roller 7 generates high-frequency vibration. Multiple accumulated materials on the top plane of conveyor belt 5 are spread out under the action of vibration, and then bounce on the inclined surface of conveyor belt 5, achieving uniform spreading and preventing accumulation. Adjusting roller 8 adaptively slides, dynamically adjusting the material drop point. Finally, the spread and dispersed sunflower seeds are sent into sterilization equipment 1 by the conveyor belt, completely eliminating sterilization dead zones and improving sterilization uniformity and production efficiency.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
