Description

Technical Field

[0001] This invention relates to the field of snack processing equipment, specifically an automatic flipping structure for roasting sunflower seeds. Background Technology

[0002] As a popular snack, the flavor and texture of sunflower seeds largely depend on the roasting process. During roasting, the seeds need to be heated evenly and turned constantly to achieve the ideal degree of cooking, crispy texture, and appealing color.

[0003] In the prior art, sunflower seed roasting equipment typically includes a fixed housing with a heating component inside to provide the heat required for roasting. Inside the housing, a cylindrical stirring drum is rotatably mounted, serving as the main working chamber for carrying and roasting the sunflower seeds. A spiral guide plate is fixedly installed on the inner wall of the stirring drum.

[0004] During the production process, a large amount of salt is usually added to the stirring drum as a heat transfer medium. When the equipment is working, the drive mechanism drives the stirring drum to rotate around its axis. The mixture of sunflower seeds and salt particles inside the drum is subjected to the combined action of gravity, centrifugal force and spiral plate. The spiral plate continuously picks up, throws down and mixes the seeds. During this process, the salt particles coat the sunflower seeds, which is intended to help the seeds absorb heat more evenly.

[0005] However, the existing stir-frying structure uses a uniform stir-frying process for all sunflower seeds. Due to the significant size difference between individual sunflower seeds in the same batch, even with salt as a heat transfer medium, smaller sunflower seeds will heat up faster due to their lighter weight, making them prone to over-frying or even burning, even under the same stir-frying drum speed and heating intensity.

[0006] Larger sunflower seeds, due to their weight and the longer time required for heat penetration, may not be fully coated by salt, resulting in insufficient heating and undercooked roasting. This uneven heating leads to significant quality differences within the same batch of roasted sunflower seeds, failing to meet the requirements for uniform roasting and affecting the overall taste and market value of the product. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic flipping structure for roasting sunflower seeds, including an outer shell, a flipping cylinder rotatably arranged inside the outer shell, a support plate fixedly installed on the front side of the outer shell, a disc plate rotatably arranged on the rear side of the flipping cylinder, and a partition hopper slidably arranged between the support plate and the disc plate.

[0008] Pusher plates are fixedly installed at equal intervals along the circumference of the inner side of the tilting cylinder. The pusher plate that rotates to the left side of the tilting cylinder has an inclined structure with the front higher than the back. A toggle is rotatably arranged between the support plate and the disc plate.

[0009] The inner side of the rotating cylinder is provided with arc-shaped bowls and sieve bowls at equal intervals along its circumference. The arc-shaped bowls and sieve bowls are arranged alternately, and the sieve bowl that rotates to the left side of the rotating cylinder is located above the corresponding arc-shaped bowl.

[0010] When the tilting drum rotates, the tilting drum pushes the sunflower seeds inside the tilting drum to the left repeatedly through the pusher plate, and the rotating agitator pushes the falling sunflower seeds into the separating hopper, so that the smaller sunflower seeds are thrown into the separating hopper, so as to reduce the heating time of the smaller sunflower seeds.

[0011] Preferably, an asynchronous motor is fixedly mounted on the outer casing, a drive gear is fixedly mounted on the output shaft of the asynchronous motor, and a driven gear that meshes with the drive gear is fixedly mounted on the outer side of the tilting cylinder.

[0012] Preferably, the left side of the separator is horizontal, the right side is inclined (lower on the right and higher on the left), and the arc-shaped wall of the separator is provided with sieve holes.

[0013] Preferably, a shaft is rotatably provided at the axis position of the dividing hopper, and a discharge plate and a dividing plate arranged radially thereon are fixedly installed on the shaft. The rotating shaft can drive the discharge plate to fit against the inner side of the dividing hopper.

[0014] Preferably, the length of the material distribution plate is shorter than that of the discharge plate, and a toothed disc is fixedly installed on the rear side of the disc plate and the outer side of the shaft. The two toothed discs are arranged in a centrally symmetrical manner, and a helical spring is provided between the toothed disc on the shaft and the outer shell.

[0015] Preferably, the rear part of the shaft has a hexagonal prism structure, and a synchronous motor is fixedly installed on the rear side of the housing. The output shaft of the synchronous motor is slidably connected to the hexagonal prism structure of the shaft.

[0016] Preferably, the actuating element has a rod-shaped structure at its axial position, and a number of comb-tooth plate structures are fixedly installed at equal intervals along the circumference of the rod-shaped structure. A number of buffers that are rotatably connected to the actuating element are provided at equal intervals along its axial direction, and a torsion spring is provided between the buffer and the actuating element.

[0017] Preferably, the arc-shaped bowl is fixedly connected to the tilting cylinder, the sieving bowl is slidably connected to the tilting cylinder, an L-shaped rod is fixedly installed on the rear side of the sieving bowl, a track ring is fixedly installed on the rear side of the disc plate, and the L-shaped rod is slidably connected inside the groove of the track ring.

[0018] Preferably, an inclined screen plate located above the left side of the dividing hopper is fixedly installed between the front side of the disc plate and the support plate. Several partitions are fixed at equal intervals along the front-back direction on the upper side of the inclined screen plate, and the partitions gradually tilt backward from top to bottom.

[0019] Preferably, an actuator motor is fixedly installed on the rear side of the disc plate, and the output shaft of the actuator motor is fixedly connected to the toggle element.

[0020] The beneficial effects of this invention are as follows: First, this invention uses a rotating tipping cylinder to drive its upper pusher plate to repeatedly push the sunflower seeds to the left. At the same time, the actuating component set between the support plate and the disc plate rotates, pushing the sunflower seeds that fall to the left due to gravity into the separating hopper. This structure allows the smaller sunflower seeds to be thrown into the separating hopper, intermittently away from the heat source on the inner wall of the tipping cylinder, effectively reducing their degree of heating. Furthermore, by extending the overall heating time of the sunflower seeds, it ultimately ensures that the heat received by sunflower seeds of different sizes is uniform, avoiding large differences in the quality of sunflower seeds within the same roasting batch.

[0021] Second, the present invention uses a buffer and torsion spring structure on the actuating component to buffer the contact of sunflower seeds. When larger sunflower seeds come into contact with the buffer, they are easier to push the buffer to rotate, thus obtaining less kinetic energy. On the other hand, smaller sunflower seeds are less likely to push the buffer to rotate and obtain more kinetic energy, thereby significantly enhancing the separation effect of sunflower seeds of different sizes. At the same time, the inclined sieve plate performs secondary screening of sunflower seeds with a longer throwing trajectory, further increasing the grading effect of sunflower seeds of different sizes.

[0022] Third, this invention uses a continuously rotating shaft to drive the discharge plate and the distribution plate to alternately scrape the sunflower seeds inside the separating hopper. When the shaft rotates, the two toothed discs mesh with each other and, in conjunction with the action of the helical spring, drive the separating hopper to vibrate back and forth. This vibration causes the large sunflower seeds inside the separating hopper to move upward, and the shorter distribution plate will preferentially scrape the upward-moving large sunflower seeds out of the separating hopper, significantly improving the screening accuracy.

[0023] Fourth, the present invention uses a rotating cylinder to drive the arc-shaped bowl and the sieving bowl to rotate synchronously. The sieving bowl, through the cooperation of the L-shaped rod and the track ring, generates back-and-forth shaking when rotating. This shaking efficiently shakes the salt particles on the sieving bowl into the corresponding arc-shaped bowl below, burying the sunflower seeds carried in the arc-shaped bowl, greatly increasing the degree of salt coating on the sunflower seeds, thereby improving the uniformity of roasting.

[0035] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic flipping structure for roasting sunflower seeds includes an outer shell 1, a flipping cylinder 2 rotatably disposed inside the outer shell 1, a support plate 3 fixedly installed on the front side of the outer shell 1, a disc plate 4 rotatably disposed on the rear side of the flipping cylinder 2, and a partition hopper 5 slidably disposed between the support plate 3 and the disc plate 4.

[0037] See Figure 4 and Figure 6 Pusher plates 21 are fixedly installed at equal intervals along the circumference of the inner side of the tilting cylinder 2. When the pusher plates 21 are rotated to the left side of the tilting cylinder 2, they have an inclined structure with the front higher than the back. A toggle piece 31 is rotatably arranged between the support plate 3 and the disc plate 4.

[0038] See Figure 2An asynchronous motor 11 is fixedly installed on the outer casing 1, and a drive gear 12 is fixedly installed on the output shaft of the asynchronous motor 11. A driven gear 13 that meshes with the drive gear 12 is fixedly installed on the outer side of the tilting cylinder 2.

[0039] It should be noted that, as Figure 1 and Figure 2 As shown, several spiral blades are fixedly installed at equal intervals along the circumference of the front side of the inner side of the rotating cylinder 2. The spiral blades are used to transport the sunflower seeds on the front side of the rotating cylinder 2 into the interior of the rotating cylinder 2 when rotating in the forward direction, and can maintain the conveying function to prevent the sunflower seeds from escaping from the rotating cylinder 2 when stir-frying. At the same time, when the rotating cylinder 2 rotates in the reverse direction, it can transport the sunflower seeds inside the rotating cylinder 2 outward to complete the feeding function.

[0040] It should also be noted that the outer shell 1 is equipped with a heating component for heating the rotating cylinder 2. The heating component is not shown in the figure, and this component is a common method in the prior art, so it will not be described in detail here.

[0041] When it is necessary to roast the sunflower seeds, the operator first starts the heating component to preheat the wall of the rotating drum 2. Then, the operator puts the salt into the rotating drum 2 and starts the asynchronous motor 11. The asynchronous motor 11 drives the rotating drum 2 to rotate clockwise through the drive gear 12 to the driven gear 13. The rotating drum 2 is then rotated clockwise. The rotating drum 2 uses its spiral blades to transport the salt to the inner wall of the rotating drum 2, thereby preheating the salt.

[0042] Once the salt grains are heated to a certain temperature, the operator adds the sunflower seeds to be roasted into the rotating drum 2. The rotating drum 2 then uses its spiral blades to transport the sunflower seeds into its interior. The sunflower seeds are heated by the temperature of the inner wall of the rotating drum 2. At the same time, the rotating drum 2 drives the pusher plate 21 to rotate synchronously, causing the pusher plate 21 to continuously push the sunflower seeds and salt grains to the upper left. When the pusher plate 21 rotates the sunflower seeds and salt grains to the upper part of the agitator 31, the sunflower seeds and salt grains slide off the pusher plate 21 under the action of gravity, thus turning the sunflower seeds and salt grains over.

[0043] It should be noted that by pushing the sunflower seeds with the inclined pusher plate 21, the sunflower seeds can slide off the pusher plate 21 and move backward along the axis of the turning cylinder 2 to a certain extent, thereby preventing the sunflower seeds from escaping from the turning cylinder 2. At the same time, when the turning cylinder 2 rotates counterclockwise, the pusher plate 21 pushes the sunflower seeds inside the turning cylinder 2 to the outside of the turning cylinder 2.

[0044] See Figure 3 and Figure 4 An actuator motor 312 is fixedly installed on the rear side of the disc plate 4, and the output shaft of the actuator motor 312 is fixedly connected to the toggle member 31.

[0045] When the operator adds sunflower seeds into the tilting drum 2, the actuator motor 312 is started, which drives the actuating component 31 to rotate clockwise. This causes the sunflower seeds sliding off the pusher plate 21 to come into contact with the rotating actuating component 31. The actuating component 31 then contacts and pushes the sunflower seeds, giving them the kinetic energy to be thrown to the right. Since the smaller sunflower seeds are also smaller in mass, they gain a greater initial horizontal velocity under the same impulse from the actuating component 31. This allows the smaller sunflower seeds to fly a greater distance horizontally, eventually falling into the separating hopper 5, thus separating the sunflower seeds by size.

[0046] It should be noted that the rotation speed of the actuating element 31 can be adjusted by those skilled in the art to push the falling sunflower seeds, thereby distinguishing the sunflower seeds by size and preventing the actuating element 31 from breaking the sunflower seeds.

[0047] When smaller sunflower seeds are thrown into the separating hopper 5, they are temporarily moved away from the inner wall of the turning cylinder 2, thereby reducing the degree of heating of the smaller sunflower seeds by the inner wall of the turning cylinder 2. This prevents the smaller sunflower seeds from being overheated and scorched under the same heating time. At the same time, the overall heating time of the sunflower seeds is extended, so that the larger sunflower seeds can be heated more, thus ensuring that the larger sunflower seeds are thoroughly cooked and ensuring the uniformity of roasting of the same batch of sunflower seeds.

[0048] It should be noted that the rotation speed of the rotating cylinder 2 and the overall heating time of the sunflower seeds by the rotating cylinder 2 can be adjusted by those skilled in the art to achieve the function of uniformly heating and thoroughly cooking the sunflower seeds in the rotating cylinder 2.

[0049] To improve the ability to distinguish between large and small melon seeds, this invention designs the following structure: (See attached diagram) Figure 2 , Figure 4 and Figure 5 An inclined screen plate 6 located above the left side of the dividing hopper 5 is fixedly installed between the front side of the disc plate 4 and the support plate 3. The inclined screen plate 6 is in a right-high-left-low posture. Several partitions 61 are fixed at equal intervals along the front-back direction on the upper side of the inclined screen plate 6. The partitions 61 gradually tilt backward from top to bottom.

[0050] When the actuating element 31 rotates, the end of the actuating element 31 furthest from its axis has the greatest linear velocity. When the end of the actuating element 31 furthest from its axis contacts the sunflower seeds, the sunflower seeds that are hit by a large impulse or are pushed by other thrown sunflower seeds are easily thrown to a greater distance, causing these sunflower seeds to be thrown and fall onto the upper side of the inclined sieve plate 6. Subsequently, these sunflower seeds slide down to the lower left along the upper side of the inclined sieve plate 6. During this process, the sunflower seeds on it are filtered by the inclined sieve plate 6, so that the smaller sunflower seeds pass through the inclined sieve plate 6 and fall directly into the separating hopper 5, while the larger sunflower seeds slide down the inclined sieve plate 6 onto the inner wall of the turning cylinder 2, thus continuing to stir-fry the larger sunflower seeds, thereby ensuring the separation effect of sunflower seeds of different sizes.

[0051] Furthermore, the upper side of the inclined screen plate 6 can be divided into several areas by several partitions 61, so that the sunflower seeds sliding on the inclined screen plate 6 can move along the guide of the partitions 61. The inclined partitions 61 increase the time that the sunflower seeds slide on the inclined screen plate 6, thereby increasing the screening effect of the inclined screen plate 6 on the sunflower seeds. The inclined partitions 61 can also guide the sunflower seeds backward to prevent the sunflower seeds from escaping from the turning cylinder 2.

[0052] It should be noted that the tilt angle of the inclined sieve plate 6 is determined by those skilled in the art through adjustment, which can ensure that the sunflower seeds slide off the inclined sieve plate 6 and prevent the sunflower seeds from being stuck on the inclined sieve plate 6.

[0053] To enhance the ability of the actuating element 31 to impart different kinetic energies to different sized sunflower seeds, thus better distinguishing between them, the present invention employs the following technical structure: (See attached document) Figure 2 , Figure 4 and Figure 6 The actuating element 31 has a rod-shaped structure at its axial position. Several comb-shaped plate structures are fixedly installed at equal intervals along its circumference on the outer side of the rod-shaped structure. Several buffer elements 311 that are rotatably connected to the actuating element 31 are arranged at equal intervals along its axial direction. A torsion spring is provided between the buffer element 311 and the actuating element 31, which is not shown in the figure.

[0054] It should be noted that the buffer 311 is composed of a central ring structure and several square rod-shaped structures arranged at equal intervals in the circumferential direction on the outside.

[0055] When the actuating member 31 rotates, it actuates the sunflower seeds through its comb plate structure. At the same time, the actuating member 31 drives the buffer member 311 on it to rotate synchronously through the torsion spring. When the buffer member 311 contacts the sunflower seeds, the sunflower seeds obstruct the rotation of the buffer member 311, thereby causing the buffer member 311 to deflect slightly relative to the actuating member 31, thus buffering the rigid contact with the sunflower seeds.

[0056] Because the smaller sunflower seeds have less mass, the impact force of the buffer 311 on them is small, resulting in a small deflection of the buffer 311. This allows the buffer 311 to maintain almost rigid contact with the smaller sunflower seeds, thus propelling them out at a higher speed. This makes the smaller sunflower seeds fly farther, while the larger sunflower seeds fly shorter, thereby amplifying the difference in flight distance between the two sizes and improving the effect of distinguishing between them.

[0057] It should be noted that the elastic performance of the torsion spring, through the selection and matching by those skilled in the art, and in conjunction with the adjustment of the rotation speed of the actuating element 31 by those skilled in the art, can achieve the effect of amplifying the difference in flight distance between large and small sunflower seeds.

[0058] See Figure 4 and Figure 8 A shaft 51 is rotatably mounted on the axis of the dividing hopper 5. A discharge plate 52 and a dividing plate 53 arranged radially on the shaft 51 are fixedly installed on the shaft 51. The rotating shaft 51 can drive the discharge plate 52 to fit against the inner side of the dividing hopper 5.

[0059] See Figure 3 and Figure 8 The rear part of the shaft 51 has a hexagonal prism structure, and a synchronous motor 54 is fixedly installed on the rear side of the housing 1. The output shaft of the synchronous motor 54 is slidably connected to the hexagonal prism structure of the shaft 51.

[0060] Continue reading Figure 3 and Figure 8 The length of the material distribution plate 53 is shorter than that of the discharge plate 52. Gear discs 41 are fixedly installed on the rear side of the disc plate 4 and the outer side of the shaft 51. The two gear discs 41 are arranged in a centrally symmetrical manner. A helical spring is provided between the gear disc 41 on the shaft 51 and the outer shell 1.

[0061] It should be noted that, as Figure 8 As shown, the toothed disc 41 is composed of a disc-shaped plate structure and several wedge-shaped structures that are fixedly installed at equal intervals along the circumference of the disc-shaped structure on its end face.

[0062] See Figure 4 , Figure 8 and Figure 9 The left side of the separator 5 is horizontal, and the right side of the separator 5 is inclined with the right side lower and the left side higher. Screen holes are opened on the arc-shaped wall of the separator 5.

[0063] When the actuating element 31 starts to rotate clockwise, the synchronous motor 54 is started to drive the shaft 51 to rotate counterclockwise. The shaft 51 drives the gear disk 41 on it to rotate. During this process, the helical spring pushes the gear disk 41 on the shaft 51 forward through its pre-compression elastic force, so that the wedge-shaped structure of the gear disk 41 on the shaft 51 rotates to contact the wedge-shaped structure of the other gear disk 41. This makes the wedge-shaped surfaces of the two gear disks 41 contact, thereby causing the gear disk 41 on the rear side of the disc plate 4 to push the gear disk 41 on the shaft 51 backward.

[0064] The gear 41 on the shaft 51 drives the shaft 51 to move backward, and at the same time the shaft 51 drives the separating bucket 5 to move backward. Then, when the gear 41 on the shaft 51 rotates to the point where the wedge-shaped structures on the two gear 41 are misaligned, the helical spring quickly pushes the gear 41 on the shaft 51 forward to reset, and at the same time causes the separating bucket 5 to move forward quickly. Through the continuous rotation of the shaft 51, the separating bucket 5 continues to move back and forth.

[0065] By continuously moving the separator 5 back and forth, the sunflower seeds and salt grains inside the separator 5 are shaken, accelerating the salt grains inside the separator 5 to fall through the sieve holes onto the cylinder wall of the rotating cylinder 2. This prevents the salt grains from overheating the small sunflower seeds. At the same time, it can also vibrate the sunflower seeds inside the separator 5. During the vibration process, the sunflower seeds will undergo convection and gap filling. Small sunflower seeds, due to their small size and light weight, are more likely to move downward through the gaps between the particles and fill the gaps at the bottom. Large sunflower seeds, on the other hand, are large in size and heavy and do not easily enter these gaps. Instead, they are pushed upward by the small sunflower seeds.

[0066] Subsequently, the rotating shaft 51 drives the dividing plate 53 to rotate to the lower part of the shaft 51, so that the dividing plate 53 extends into the interior of the dividing hopper 5 and rotates, thereby pushing the large sunflower seeds that have moved to the upper part of the dividing hopper 5 to the right. As the dividing plate 53 rotates to the right tilted position of the dividing hopper 5, the large sunflower seeds in the dividing hopper 5 are pushed to the outside of the dividing hopper 5 by the dividing plate 53 and fall onto the cylinder wall of the tilting cylinder 2 to be heated, thereby further refining the differentiation effect of large and small sunflower seeds and improving the heating uniformity.

[0067] Subsequently, the shaft 51 drives the discharge plate 52 to rotate into the interior of the dividing hopper 5, so that the discharge plate 52 rotates against the inner arc wall of the dividing hopper 5, thereby pushing all the sunflower seeds inside the dividing hopper 5 onto the cylinder wall of the rotating cylinder 2, so that the small sunflower seeds are heated again.

[0068] See Figure 4 and Figure 7 The inner side of the rotating cylinder 2 is provided with arc-shaped bowls 22 and sieve bowls 23 at equal intervals along its circumference. The arc-shaped bowls 22 and sieve bowls 23 are arranged alternately. When the sieve bowl 23 is rotated to the left of the rotating cylinder 2, it is located above the corresponding arc-shaped bowl 22. The arc-shaped wall of the sieve bowl 23 is provided with sieve holes for sieving salt particles.

[0069] When the rotating drum 2 starts to rotate, it drives the arc-shaped bowl 22 and the sieve bowl 23 on it to rotate synchronously. When the arc-shaped bowl 22 and the sieve bowl 23 rotate, they are filled with melon seeds and salt. When the arc-shaped bowl 22 and the sieve bowl 23 rotate to the left side of the rotating drum 2, the salt in the sieve bowl 23 falls through the sieve holes of the sieve bowl 23 under the action of gravity and falls onto the arc-shaped bowl 22. This makes the falling salt buried in the arc-shaped bowl 22, which greatly increases the degree of salt coating on the melon seeds and thus improves the uniformity of roasting.

[0070] It should be noted that when the salt grains inside the sieving bowl 23 fall into the arc-shaped bowl 22, the sunflower seeds inside the sieving bowl 23 lack salt coating. However, when the arc-shaped bowl 22 and the sieving bowl 23 rotate to the right side of the rotating cylinder 2, their openings face downwards, causing the sunflower seeds and salt grains inside the arc-shaped bowl 22 and the sieving bowl 23 to fall onto the inner wall of the rotating cylinder 2. There, they are pushed and mixed again by the pusher plate 21, thus avoiding the situation where the sunflower seeds inside the sieving bowl 23 are not heated as evenly as those inside the arc-shaped bowl 22. Furthermore, since the sunflower seeds and salt grains in the arc-shaped bowl 22 are already mixed, the sieving bowl 23 only needs to let out a small amount of salt grains to cover the opening of the arc-shaped bowl 22, reducing the impact of the reduced salt grains on the heating of the sunflower seeds in the sieving bowl 23.

[0071] To increase the speed at which salt particles fall through the sieving bowl 23, the following structure was designed in this embodiment: (See attached document for further details) Figure 4 and Figure 7 The arc-shaped bowl 22 is fixedly connected to the tilting cylinder 2, the sieve bowl 23 is slidably connected to the tilting cylinder 2, an L-shaped rod 231 is fixedly installed on the rear side of the sieve bowl 23, and a track ring 232 is fixedly installed on the rear side of the disc plate 4. The L-shaped rod 231 is slidably connected inside the groove of the track ring 232.

[0072] It should be noted that the slots on the trajectory ring 232 have a closed-loop wave structure.

[0073] When the sieving bowl 23 rotates synchronously with the tilting cylinder 2, the sieving bowl 23 drives the L-shaped rod 231 on it to move along the wave structure groove of the track ring 232. This causes the L-shaped rod 231 to move back and forth continuously under the guidance of the track ring 232, which in turn causes the L-shaped rod 231 to drive the sieving bowl 23 to move back and forth synchronously. This allows the salt grains and sunflower seeds in the sieving bowl 23 to be continuously shaken, so that the salt grains can be quickly sieved out of the sieving bowl 23, thereby quickly burying the sunflower seeds in the arc-shaped bowl 22.

[0074] See Figures 1 to 9The present invention further includes the following steps when stir-frying sunflower seeds: First, the operator starts the heating component to preheat the wall of the rotating cylinder 2. Then, the operator puts salt into the rotating cylinder 2 and starts the asynchronous motor 11, so that the rotating cylinder 2 rotates clockwise to preheat the salt.

[0075] The second step involves the operator adding sunflower seeds into the rotating drum 2, which heats the seeds on the inner wall of the rotating drum 2. At the same time, the pusher plate 21 continuously pushes the sunflower seeds and salt grains to the upper left. Under the action of gravity, the sunflower seeds and salt grains slide off the pusher plate 21, thus turning the sunflower seeds and salt grains over.

[0076] The third step is to start the actuator motor 312 to drive the toggle member 31 to rotate clockwise. The toggle member 31 drives the buffer member 311 on it to rotate synchronously through the torsion spring, so that the buffer member 311 pushes the sunflower seeds to fly towards the separating bucket 5, and amplifies the difference in flight distance between large and small sunflower seeds, thus improving the effect of distinguishing between large and small sunflower seeds.

[0077] In the fourth step, some sunflower seeds that are thrown and fall onto the upper side of the inclined screen plate 6 slide down to the lower left along the upper side of the inclined screen plate 6. During this process, the sunflower seeds on the inclined screen plate 6 are filtered, so that the smaller sunflower seeds pass through the inclined screen plate 6 and fall directly into the separator hopper 5.

[0078] Fifth step, start the synchronous motor 54 to drive the shaft 51 to rotate counterclockwise, so that the separating hopper 5 moves back and forth continuously, and shakes the sunflower seeds and salt grains inside the separating hopper 5, accelerating the salt grains inside the separating hopper 5 to fall through the sieve holes onto the cylinder wall of the rotating cylinder 2, while at the same time moving the large sunflower seeds to the top of the separating hopper 5.

[0079] In the sixth step, the shaft 51 drives the material distribution plate 53 to push the large sunflower seeds that have moved to the upper part of the separating hopper 5 to the left, so that the large sunflower seeds in the separating hopper 5 are pushed to the outside of the separating hopper 5 by the material distribution plate 53 and fall onto the cylinder wall of the rotating cylinder 2 to be heated, thereby further refining the differentiation effect of large and small sunflower seeds and improving the heating uniformity.

[0080] In the seventh step, the shaft 51 drives the discharge plate 52 to rotate into the interior of the dividing hopper 5, so that the discharge plate 52 rotates against the inner arc wall of the dividing hopper 5, thereby pushing all the sunflower seeds inside the dividing hopper 5 onto the cylinder wall of the rotating cylinder 2, so that the small sunflower seeds are heated again.

[0081] In the eighth step, the rotating cylinder 2 drives the arc-shaped bowl 22 and the sieving bowl 23 on it to rotate synchronously. At the same time, the track ring 232 pushes the sieving bowl 23 to shake continuously, so that the salt grains fall quickly from the sieving bowl 23 into the arc-shaped bowl 22, burying the sunflower seeds in the arc-shaped bowl 22, greatly increasing the degree of salt coating on the sunflower seeds, and thus improving the uniformity of roasting.
