Description

Technical Field

[0001] This invention relates to the field of sunflower seed processing technology, and in particular to a sunflower seed roasting equipment with a debris extraction mechanism. Background Technology

[0002] As a popular snack, the roasting process of sunflower seeds directly affects their taste, flavor, and appearance. Traditional sunflower seed processing mainly relies on drum-type roasters or fixed ovens for heat treatment. While the drum equipment heats the seeds by constantly rotating them, this method is generally inefficient. A large amount of heat is lost through the surface and gaps of the pot, resulting in energy waste. More importantly, the heating is uneven, with significant temperature differences in different parts of the seeds, easily leading to some seeds burning while others remain uncooked. At the same time, the intense collisions and friction between the seeds and the inner wall of the drum, as well as between the seeds themselves, easily cause the shells to break or even the kernels to crumble. This not only reduces the integrity and appearance of the product but also affects its final taste and economic value.

[0003] During the roasting process, sunflower seeds generate a large amount of fine debris, dust, and immature particles due to heat and friction. These substances accumulate inside the equipment and, under continuous high-temperature roasting, easily carbonize, producing harmful substances that contaminate the entire batch of products and impart unpleasant flavors such as burnt and bitterness. Severe carbonization can even produce smoke, posing a safety hazard. Traditional equipment generally lacks online cleaning capabilities, requiring manual cleaning after shutdown. Frequent production interruptions not only reduce efficiency but also cause significant heat loss each time the equipment is turned on, requiring renewed energy consumption to restore operating temperature, further increasing production costs.

[0004] To address these issues, the industry has proposed several improvement technologies. For example, hot air circulation ovens are used, utilizing forced convection of hot air to improve heating uniformity. While this method improves heat distribution to some extent, it has significant drawbacks. Insufficient airflow speed and control precision result in uneven hot air distribution; excessively strong airflow can easily blow the sunflower seeds, increasing their collision with the equipment's inner wall and other seeds, leading to a higher breakage rate. Another improvement involves adding mechanical stirring devices, such as stirring paddles or rakes, inside the equipment to ensure more even heating. However, the rigid stirring components directly contact the sunflower seeds, becoming a new source of breakage themselves and failing to fundamentally solve the problem of protecting the seeds' shape.

[0005] For debris handling, a common design involves installing a metal screen at the bottom of the equipment. Debris generated during baking falls through the screen holes into a dust collection hopper for initial separation. However, the screen holes are easily clogged by moist debris and grease, making cleaning and maintenance very troublesome, and automatic discharge during operation is not possible. Some have attempted to introduce external suction devices, connecting a vacuum fan to one side of the equipment. However, simple suction designs often fail to match the baking process well; the suction power is unstable. Excessive suction draws away a large amount of heat and small seeds, disrupting the stable temperature field inside the oven; insufficient suction results in poor extraction, leaving impurities behind. None of these solutions achieve a balance between production continuity, thermal stability, and product cleanliness.

[0006] The present invention aims to solve the technical problems existing in the prior art. To this end, a chip extraction type sunflower seed roasting device is proposed. Summary of the Invention

Detailed Implementation

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0031] Example 1, please refer to Figure 1 , Figure 2 In this embodiment of the invention, a chip extraction type sunflower seed roasting device includes a fixed mounting base 2, with fixed mounting plates 1 symmetrically arranged at the lower end of the fixed mounting base 2. Each fixed mounting plate 1 is provided with a plurality of fixed mounting holes. A swing mounting frame 4 is rotatably arranged at the upper end of the fixed mounting base 2, and a swing mounting plate 5 is arranged at the upper end of the swing mounting frame 4. The fixed mounting base 2 and the swing mounting frame 4 are connected by a steering drive shaft 3. The device also includes a rolling roasting mechanism and a chip extraction mechanism, including a directional flow extraction module and a chip instantaneous discharge module.

[0032] The fixed mounting base 2 is installed at the target position through the fixed mounting plate 1 and its fixed mounting holes. The tilt angle of the swing mounting bracket 4 and the swing mounting plate 5 is adjusted by the steering drive shaft 3, thereby realizing the angle adjustment of the rolling roasting mechanism and the chip extraction mechanism. This facilitates the import and export of sunflower seeds and the turning during roasting. It can also work with the directional flow extraction module and the instant chip discharge module to collect and export chips, ensuring that the sunflower seeds are clean after roasting.

[0033] Example 2, based on Example 1, please refer to... Figures 1-5 In this embodiment of the invention, the rolling baking mechanism includes a double-layer rotating mounting cylinder 24 disposed on a swing mounting plate 5. A spherical mounting cover 9 is disposed at one end of the double-layer rotating mounting cylinder 24, and a fixed mounting plate 15 is disposed at the other end of the double-layer rotating mounting cylinder 24. An inlet and outlet cover plate 16 is rotatably disposed on the fixed mounting plate 15 near the inner wall of the double-layer rotating mounting cylinder 24. A spiral guiding heating plate 26 is disposed along the axial direction on the inner wall of the double-layer rotating mounting cylinder 24. The outer wall of the double-layer rotating mounting cylinder 24 is fitted with a vacuum insulation cylinder 17. The outer walls of the double-layer rotating mounting cylinder 24 at both ends of the vacuum insulation cylinder 17 are symmetrically provided with steering gear rings 12. The upper side of the swing mounting plate 5 is symmetrically fixedly installed with steering drive components 10 in conjunction with the steering gear rings 12. The ends of the steering drive components 10 are provided with drive gears 11 through rotating shafts. The drive gears 11 mesh with the steering gear rings 12. A positioning rotating ring 6 is provided at the middle position of the outer side of the vacuum insulation cylinder 17, and a positioning rotating sleeve 7 is provided on the upper side of the swing mounting plate 5 in conjunction with the positioning rotating ring 6. First, adjust the tilt angle of the swing mounting plate 5 so that the height of one end of the fixed mounting plate 15 is higher than the height of one end of the spherical mounting cover 9. At this time, open the inlet and outlet cover 16, pour in the sunflower seeds to be roasted, and then close the inlet and outlet cover 16. Then, adjust the tilt angle of the swing mounting plate 5 and start the steering drive component 10 to make the drive gear 11 rotate. The drive gear 11 meshes with the steering gear ring 12 to realize the rotation of the double-layer rotating mounting cylinder 24 and the spiral guiding heating plate 26 on it. As the spiral guiding heating plate 26 rotates to guide the material and heat and roast, the moisture of the sunflower seeds is released into the double-layer rotating mounting cylinder 24. As roasting continues, the temperature rises further. After a period of time, the roasting is completed. Change the tilt angle of the double-layer rotating mounting cylinder 24 again so that the height of the fixed mounting plate 15 is lower than the height of the spherical mounting cover 9. With the rotation of the double-layer rotating mounting cylinder 24, the roasted sunflower seeds inside are taken out from the opened inlet and outlet cover 16, and the roasting of the sunflower seeds is completed. The steering drive 10 can rotate in a specific direction according to different baking steps and stages, and can also alternate between forward and reverse rotation for a period of time. During the roasting process of sunflower seeds, the vacuum insulation cylinder 17 can lock in the heat inside the double-layer rotating mounting cylinder 24, which makes the roasting temperature rise rapidly, reduces heat loss, reduces heating energy consumption, and improves the energy utilization rate of the equipment. While the double-layer rotating mounting cylinder 24 rotates, the positioning rotating ring 6 and the positioning rotating sleeve 7 rotate together, ensuring that there is no misalignment during the rotating baking process and ensuring the stable operation of the equipment.

[0034] Example 3, based on Example 1, please refer to... Figures 4-7 , Figure 9 In this embodiment of the invention, the directional flow extraction module includes an extraction guide cylinder 29 horizontally arranged in the middle of the double-layer rotating mounting cylinder 24. One end of the extraction guide cylinder 29 is connected to the fixed mounting plate 15, and the other end of the extraction guide cylinder 29 is provided with a conical flow-gathering cylinder 27. A plurality of strip-shaped extraction guide holes 30 are provided at equal angles on the outer side of the extraction guide cylinder 29. An extraction drive component 13 is provided in the middle of the fixed mounting plate 15. The extraction drive component 13 is mounted on the fixed mounting plate 15 through a fixed mounting bracket 14 arranged at equal angles. An extraction rotating column 28 is provided at the end of the extraction drive component 13 through a rotating shaft. The extraction rotating column 28 extends into the extraction guide cylinder 29, and a directional spiral guide plate 31 is provided on the outer side of the extraction rotating column 28 in conjunction with the inner wall of the extraction guide cylinder 29. The outer side of the extraction guide tube 29 is covered with a filter screen tube 25, and the tube wall of the filter screen tube 25 and the tube wall of the extraction guide tube 29 are fitted with a clearance. A guide net cylinder 19 is provided on the spherical mounting cover 9 directly opposite the conical flow-gathering cylinder 27. A conical flow-guiding disk 21 is movably arranged inside the guide net cylinder 19. A cylindrical return cavity 22 is provided inside the cylinder wall of the double-layer rotating mounting cylinder 24. The cylindrical return cavity 22 at one end of the double-layer rotating mounting cylinder 24 facing the spherical mounting cover 9 has an open structure, and the other end of the cylindrical return cavity 22 has a closed structure. An arc-shaped flow-guiding ring 18 is provided on the inner side of one end of the open structure double-layer rotating mounting cylinder 24. A plurality of return flow guiding holes 23 are evenly arranged on the inner wall of the double-layer rotating mounting cylinder 24, and all return flow guiding holes 23 are connected to the cylindrical return cavity 22. As the sunflower seeds rotate and roast inside the double-layer rotating installation cylinder 24, the dust and other impurities mixed in with the sunflower seeds, as well as the peeling and charring debris produced during the roasting process, will affect the cleanliness of the sunflower seeds inside. Over time, they may produce harmful substances due to heat, or they may burn easily due to their small or thin size, which will significantly affect the taste. Therefore, it is necessary to remove the dust, impurities and debris in time to improve the cleanliness and taste of the sunflower seeds. Specifically, as the sunflower seeds are roasted, the extraction drive 13 is activated, causing the extraction rotating column 28 and its directional spiral guide plate 31 to rotate at high speed via the rotating shaft. This draws air between the extraction guide cylinder 29 and the double-layer rotating mounting cylinder 24 into the strip-shaped extraction guide hole 30, and then directs it from the conical converging cylinder 27 to the conical guide plate 21. The airflow from the conical guide plate 21 impacts the guide mesh cylinder 19. Subsequently, a continuous stream of airflow is introduced from the conical converging cylinder 27 to the conical guide plate 21. The airflow from the guide mesh cylinder 19 continues to flow along the inner wall of the spherical mounting cover 9, and under the guidance of the arc-shaped guide ring 18, it enters the cylindrical return cavity 22, and finally returns to the space between the extraction guide cylinder 29 and the double-layer rotating mounting cylinder 24 through the return guide hole 23. The air between the extraction guide cylinder 29 and the double-layer rotating mounting cylinder 24 passes through the filter screen cylinder 25 before entering the strip-shaped extraction guide hole 30. On the one hand, this prevents the sunflower seeds from directly entering the strip-shaped extraction guide hole 30 and provides a buffer for the sunflower seeds that fall during the rotation and roasting process of the spiral material guiding heating plate 26. On the other hand, it works with the spiral material guiding heating plate 26 to act as a cylindrical heat equalization structure to ensure that the sunflower seeds are heated evenly, avoiding heat accumulation and charring, which would affect the quality of the sunflower seeds.

[0035] Example 4, based on Example 3, please refer to... Figure 4 , Figure 5 , Figures 8-10 In this embodiment of the invention, the instantaneous debris discharge module includes a guide mounting cylinder 8 connected to one end of a guide mesh cylinder 19. The guide mounting cylinder 8 extends out of a spherical mounting cover 9. A plurality of discharge holes 20 are provided on the cylinder wall of the guide mounting cylinder 8 extending out of the spherical mounting cover 9. A directional sliding column 34 is provided at the middle position of the end of the guide mounting cylinder 8. A directional sliding cylinder 33 is provided on the side of the conical guide plate 21 facing the directional sliding column 34. A return spring 32 is provided at the end of the directional sliding column 34 and the bottom of the directional sliding cylinder 33.

[0036] As the conical concentrator 27 directs the airflow, dust, small particles, and debris in the sunflower seeds are guided to one side of the conical guide plate 21. After a period of time, the conical guide plate 21, together with the guide mesh 19, captures more and more dust, small particles, and debris, and the wind pressure on the conical guide plate 21 increases. At this time, the return spring 32 is compressed, and the conical guide plate 21 moves towards the guide mounting cylinder 8 with the cooperation of the directional sliding column 34 and the directional sliding cylinder 33 until the conical guide plate 21 moves to the discharge hole 20. At this time, the airflow carrying the captured dust, small particles, and debris is instantly discharged from the discharge hole 20. At this time, the flowability of the guide mesh 19 is restored, and the wind pressure is insufficient to support the conical guide plate 21 in the guide mounting cylinder 8. Under the action of the return spring 32, the conical guide plate 21 is reset. Repeating the above steps can ensure that the sunflower seed roasting process is always clean and hygienic. During the instantaneous discharge of captured dust, small particles and debris, a large amount of water vapor inside the equipment is also discharged simultaneously. The guide mesh cylinder 19 between the conical guide plate 21 and the guide mounting cylinder 8 can cooperate with the discharge hole 20 to achieve normal water vapor dissipation and air pressure balance.
