Description

Technical Field

[0001] This invention belongs to the field of material roasting technology, and particularly relates to a sesame roasting device for sesame oil production, and a roasting method for the sesame roasting device for sesame oil production. Background Technology

[0002] In sesame oil production, sesame roasting is a core process that affects the aroma and oil yield of the oil. This process must strictly follow the continuous process requirements of low-temperature preheating, high-temperature roasting, and slight cooling. Most existing sesame roasting equipment used in sesame oil production is a single-compartment drum structure with no functional partition design inside the drum. The entire roasting process is completed in a single compartment, relying solely on the rotation of the drum to achieve natural rolling and turning of the material. It is also equipped with a simple feeding structure to complete the feeding. This is currently the mainstream equipment form for sesame roasting in the industry.

[0003] The existing single-compartment drum roasting cylinder cannot complete the entire process of sesame preheating and roasting in the same equipment. It requires precise control of roasting time and rapid discharge after roasting. If the transfer is not timely, it will easily lead to poor consistency of sesame roasting quality. In addition, it requires natural air cooling or the installation of a cooling mechanism to cool down the roasting cylinder, which is difficult to adapt to the industrialized and refined production needs of sesame oil. Summary of the Invention

[0004] To address the problems in the prior art, the present invention proposes the following technical solution: A sesame roasting apparatus for sesame oil production includes: The stir-frying drum has two partitions inside, which divide the internal space of the stir-frying drum into a preheating chamber, a stir-frying chamber and a micro-cooling chamber in the direction of the discharge port. The space in the preheating chamber gradually decreases in the direction of the feed port of the stir-frying drum. The bottom of the partition is provided with an opening and closing component that connects the preheating chamber and the stir-frying chamber or the stir-frying chamber and the micro-cooling chamber. Mounting rod, both of the partition plates are fixedly mounted on the mounting rod, one end of the mounting rod extends through the roasting drum to the outside, and the other end of the mounting rod is provided with an expansion cylinder with a quantitative feeding mechanism. One end of the expansion cylinder is attached to the corresponding partition plate, the space of the expansion cylinder gradually decreases towards the feed inlet of the roasting drum, and the end of the expansion cylinder is rotatably sealed with the feed inlet of the roasting drum. A partition plate is provided on the outer circumference of the expansion cylinder and is fixedly connected to the roasting drum. The quantitative feeding mechanism supplies material into the preheating chamber. The material enters between two adjacent partitions and is spread thinly in the preheating chamber. The rotation of the stir-frying drum causes the material to move along the surface of the expansion cylinder by the partitions. When the material exceeds the middle of the expansion cylinder, it moves to the other side due to gravity, completing the stir-frying action. The material passes through the low-temperature preheating of the preheating chamber, the high-temperature stir-frying of the stir-frying chamber, and the cooling of the micro-cooling chamber in sequence to complete the entire stir-frying process. During the material transfer process, the opening and closing components cooperate to control the connection and sealing of the partitions to complete the process-oriented stir-frying work.

[0005] As a preferred embodiment of the above technical solution, the opening and closing assembly includes a flip plate, a first rack, and a second rack. One end of the flip plate is provided with a rotating shaft that is rotatably inserted into a partition plate. Both ends of the rotating shaft are provided with torsion springs, and the two ends of the torsion springs are respectively fixedly connected to the rotating shaft and the partition plate. The middle surfaces of the two rotating shafts are respectively provided with a first gear and a second gear. The first gear is located in the partition plate between the preheating chamber and the frying chamber, and the first gear is fixedly connected to the corresponding rotating shaft. The second gear is located in the partition plate between the frying chamber and the micro-cooling chamber, and a ratchet mechanism is provided between the second gear and the corresponding rotating shaft. The second rack pushes the second gear to rotate before the first rack. The corresponding rotating shaft drives the tilting plate to deflect and open the partition between the roasting chamber and the micro-cooling chamber. The roasted material can then enter the micro-cooling chamber for cooling. After the partition closes, the first rack pushes the first gear to rotate. The corresponding rotating shaft drives the tilting plate to deflect and open the partition between the preheating chamber and the roasting chamber. The preheated material can then enter the roasting chamber for roasting.

[0006] As a preferred embodiment of the above technical solution, the second rack meshes with the second gear, and the distance between the first rack and the first gear is 1.5 times the length of the first rack. When the second rack and the first rack move synchronously, the second rack drives the second gear to rotate. After the second rack leaves the position of the second gear, the first rack contacts the first gear and pushes it to rotate.

[0007] As a preferred embodiment of the above technical solution, the first rack and the second rack are fixedly connected to the same moving rod. The moving rod reciprocates inside the mounting rod, and the end of the moving rod is connected to an external driving component. The moving rod is used to simultaneously push the first rack and the second rack to reciprocate.

[0008] As a preferred embodiment of the above technical solution, it also includes a mounting frame and a large gear ring. Both ends of the mounting frame are provided with a set of bearing rollers. The ends of the bearing rollers are movably inserted into the roasting drum. The large gear ring is fixedly connected to the roasting drum. A drive gear connected to an external drive device is provided on one side of the large gear ring.

[0009] As a preferred embodiment of the above technical solution, the mounting frame is provided with a mounting base at its bottom, one end of the mounting frame is hinged to the mounting base, and a cylinder is provided between the other end of the mounting frame and the mounting base. The cylinder pushes the mounting frame to change the stir-frying drum from a horizontal state to an inclined state.

[0010] As a preferred embodiment of the above technical solution, the end of the mounting rod is fixed on the mounting frame, and the mounting rod deflects synchronously with the mounting frame and the frying drum.

[0011] As a preferred embodiment of the above technical solution, a heating module is also included, which is disposed outside the preheating chamber and the frying chamber, as well as inside the expansion cylinder.

[0012] A sesame roasting method for sesame oil production using a sesame roasting device, characterized by comprising the following steps: S1. Start the rotation drive structure of the roasting drum to keep the roasting drum rotating at a constant speed. Then, through the quantitative feeding mechanism installed at the end of the expansion cylinder, quantitatively feed sesame material into the preheating chamber of the roasting drum. The material enters between two adjacent partition plates on the outer circumference of the expansion cylinder to form a thin layer of material. S2. As the stir-frying drum continues to rotate, the separators drive the thinly spread material to move along the surface of the expansion drum. When the material moves to the middle of the expansion drum, it naturally moves to the other side of the expansion drum due to gravity, completing one stir-frying action. The material achieves low-temperature uniform preheating in the preheating chamber through multiple stir-frying actions. S3. After the material in the preheating chamber has been preheated, control the opening and closing component to open the connecting channel between the preheating chamber and the roasting chamber. As the roasting drum rotates, the preheated material is transferred from the preheating chamber to the roasting chamber. Then the opening and closing component resets and re-seals the channel between the preheating chamber and the roasting chamber. S4. The material entering the frying chamber completes the high-temperature frying process as the frying drum rotates, achieving full heating and cooking of the material. S5. After the material in the roasting chamber has been roasted, control the opening and closing component to open the connecting channel between the roasting chamber and the micro-cooling chamber. As the roasting drum rotates, the roasted material is transferred from the roasting chamber to the micro-cooling chamber. Then the opening and closing component resets and re-seals the channel between the roasting chamber and the micro-cooling chamber. S6. The material entering the micro-cooling chamber rotates with the roasting drum and undergoes natural micro-cooling in an environment without additional heating, thus completing the entire sesame roasting process. Afterward, the cooled roasted sesame seeds can be discharged from the discharge port of the roasting drum.

[0013] The beneficial effects of this invention are as follows: 1. The interior of the roasting drum is divided into a preheating chamber, a roasting chamber, and a micro-cooling chamber by two partition plates. This allows the material to complete the entire process of "low-temperature preheating - high-temperature roasting - micro-cooling" within the same drum. The space in both the preheating chamber and the expansion chamber gradually decreases towards the feed inlet. The space within both chambers guides the material to naturally gather and form a thin layer, avoiding uneven heating caused by accumulation. As the drum rotates, the material moves along the surface of the expansion chamber to the middle and then flips over due to gravity, forming a gentle and thorough roasting action. This prevents damage to the sesame seed coat and premature oil separation. The opening and closing components allow the preheated material to accurately enter the roasting chamber and the roasted material to smoothly transfer to the micro-cooling chamber. This achieves continuous operation from quantitative feeding, zoned roasting to cooling, significantly improving production efficiency. 2. By utilizing the positional difference between the first and second racks, the micro-cooling chamber channel is opened first, followed by the preheating chamber channel. After the high-temperature roasted material enters the micro-cooling chamber, the low-temperature preheated material is then sent into the roasting chamber, effectively avoiding the mixing of materials at different stages. The ratchet mechanism can limit the unidirectional deflection of the flip plate corresponding to the second rack, thus ensuring that the material transfer path is unique and controllable, ensuring the precise repetition of the material transfer action, and making the preheating, roasting, and cooling stages of each batch of sesame seeds smooth, further guaranteeing the uniformity of the roasted material quality.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0017] Example Figures 1-6 The sesame roasting device for sesame oil production includes: The stir-frying drum 10 has two partition plates 20 inside. The two partition plates 20 divide the internal space of the stir-frying drum 10 into a preheating chamber 11, a stir-frying chamber 12 and a micro-cooling chamber 13 in the direction of the discharge port. The space of the preheating chamber 11 gradually decreases in the direction of the feed port of the stir-frying drum 10. The bottom of the partition plate 20 is provided with an opening and closing assembly 50 connecting the preheating chamber 11 and the stir-frying chamber 12 or the stir-frying chamber 12 and the micro-cooling chamber 13. Mounting rod 30, both of the partition plates 20 are fixedly mounted on mounting rod 30. One end of mounting rod 30 extends through the roasting drum 10 to the outside. The other end of mounting rod 30 is provided with an expansion cylinder 40 with a quantitative feeding mechanism 41. One end of expansion cylinder 40 is attached to the corresponding partition plate 20. The space of expansion cylinder 40 gradually decreases towards the feed inlet of roasting drum 10. The end of expansion cylinder 40 is rotatably sealed to the feed inlet of roasting drum 10. A partition plate 42 is provided on the outer circumference of expansion cylinder 40 and is fixedly connected to roasting drum 10. The quantitative feeding mechanism 41 supplies material into the preheating chamber 11. The material enters between two adjacent partition plates 42 and is spread thinly on the preheating chamber 11. The rotation of the stir-frying drum 10 causes the material to move along the surface of the expansion cylinder 40 by the partition plates 42. When the material exceeds the middle of the expansion cylinder 40, it moves to the other side due to gravity to complete the stir-frying action. The material passes through the low temperature preheating of the preheating chamber 11, the high temperature stir-frying of the stir-frying chamber 12, and the cooling of the micro-cooling chamber 13 in sequence to complete the entire stir-frying process. During the material transfer process, the opening and closing component 50 cooperates with the control of the connection and sealing of the partition plate 20 to complete the process-oriented stir-frying work.

[0018] It also includes a heating module, which is located outside the preheating chamber 11 and the frying chamber 12, and inside the expansion cylinder 40.

[0019] Two partition plates 20 divide the interior of the roasting drum 10 into a preheating chamber 11, a roasting chamber 12, and a micro-cooling chamber 13, allowing the material to complete the entire process of "low-temperature preheating - high-temperature roasting - micro-cooling" within the same drum. The space in both the preheating chamber 11 and the expansion chamber 40 gradually decreases towards the feed inlet, and the space within them guides the material to naturally gather and form a thin layer, avoiding uneven heating caused by accumulation. Furthermore, as the drum rotates, the material moves along the surface of the expansion chamber 40 to the middle and then flips over due to gravity, forming a gentle and thorough roasting action, preventing damage to the sesame seed coat and premature oil separation. With the addition of the opening and closing components 50, the preheated material is precisely fed into the roasting chamber 12, and the roasted material is smoothly transferred to the micro-cooling chamber 13, realizing continuous operation from quantitative feeding, zoned roasting to cooling, and significantly improving production efficiency.

[0020] The sesame roasting method for sesame oil production using a sesame roasting device includes the following steps: S1. Start the rotation drive structure of the roasting drum 10 to keep the roasting drum 10 rotating at a constant speed. Then, through the quantitative feeding mechanism 41 installed at the end of the expansion cylinder 40, quantitatively feed sesame material into the preheating chamber 11 of the roasting drum 10. The material enters between two adjacent partition plates 42 on the outer circumference of the expansion cylinder 40 to form a thin layer of material. S2. As the stir-frying drum 10 continues to rotate, the separator 42 drives the thinly spread material to move along the surface of the expansion drum 40. When the material moves to the middle position of the expansion drum 40, the material naturally moves to the other side of the expansion drum 40 due to gravity, completing one stir-frying action. The material achieves low-temperature uniform preheating in the preheating chamber 11 through multiple stir-frying actions. S3. After the material in the preheating chamber 11 has been preheated, control the opening and closing component 50 to open the connecting channel between the preheating chamber 11 and the frying chamber 12. As the frying drum 10 rotates, the preheated material is transferred from the preheating chamber 11 to the frying chamber 12. Then the opening and closing component 50 is reset and the channel between the preheating chamber 11 and the frying chamber 12 is resealed. S4. The material entering the frying chamber 12 rotates with the frying drum 10 to complete the high-temperature frying operation, so as to achieve full heating and cooking of the material. S5. After the material in the roasting chamber 12 has been roasted, control the opening and closing component 50 to open the connecting channel between the roasting chamber 12 and the micro-cooling chamber 13. As the roasting drum 10 rotates, the roasted material is transferred from the roasting chamber 12 to the micro-cooling chamber 13. Then the opening and closing component 50 is reset and the channel between the roasting chamber 12 and the micro-cooling chamber 13 is resealed. S6. The material entering the micro-cooling chamber 13 rotates with the roasting drum 10 and undergoes natural micro-cooling in an environment without additional heating, thus completing the entire sesame roasting process. The cooled roasted sesame seeds are then discharged from the outlet of the roasting drum 10.

[0021] Figures 2-6 In the above, the opening and closing assembly 50 includes a flip plate 51, a first rack 52 and a second rack 53. One end of the flip plate 51 is provided with a rotating shaft 56 that is rotatably inserted into the partition plate 20. Both ends of the rotating shaft 56 are provided with torsion springs, and the two ends of the torsion springs are respectively fixedly connected to the rotating shaft 56 and the partition plate 20. The middle surfaces of the two rotating shafts 56 are respectively provided with a first gear 54 and a second gear 55. The first gear 54 is located in the partition plate 20 between the preheating chamber 11 and the frying chamber 12, and the first gear 54 is fixedly connected to the corresponding rotating shaft 56. The second gear 55 is located in the partition plate 20 between the frying chamber 12 and the micro-cooling chamber 13. A ratchet mechanism 57 is provided between the second gear 55 and the corresponding rotating shaft 56. The second rack 53 drives the second gear 55 to rotate before the first rack 52. The corresponding rotating shaft 56 drives the tilting plate 51 to deflect and open the partition plate 20 between the frying chamber 12 and the micro-cooling chamber 13. The frying material can then enter the micro-cooling chamber 13 for cooling. After the partition plate 20 is closed, the first rack 52 drives the first gear 54 to rotate. The corresponding rotating shaft 56 drives the tilting plate 51 to deflect and open the partition plate 20 between the preheating chamber 11 and the frying chamber 12. The preheated material can then enter the frying chamber 12 for frying.

[0022] The second rack 53 meshes with the second gear 55. The distance between the first rack 52 and the first gear 54 is 1.5 times the length of the first rack 52. When the second rack 53 and the first rack 52 move synchronously, the second rack 53 drives the second gear 55 to rotate. After the second rack 53 leaves the position of the second gear 55, the first rack 52 contacts the first gear 54 and pushes it to rotate.

[0023] The first rack 52 and the second rack 53 are fixedly connected to the same moving rod 58. The moving rod 58 reciprocates inside the mounting rod 30, and the end of the moving rod 58 is connected to an external driving component. The moving rod 58 is used to simultaneously push the first rack 52 and the second rack 53 to reciprocate.

[0024] By utilizing the positional difference between the first rack 52 and the second rack 53, the micro-cooling chamber 13 is opened first, followed by the preheating chamber 11. After the material roasted at high temperature enters the micro-cooling chamber 13, the material preheated at low temperature is then sent into the roasting chamber 12, effectively avoiding the mixing of materials at different stages. The ratchet mechanism 57 can limit the unidirectional deflection of the flip plate 51 corresponding to the second rack 53, thus ensuring that the material transfer path is unique and controllable, ensuring the precise repetition of the material transfer action, and making the preheating, roasting, and cooling stages of each batch of sesame seeds smooth, further ensuring the uniformity of the roasted material quality.

[0025] Figure 1 The device also includes a mounting frame 61 and a large gear ring 62. Both ends of the mounting frame 61 are provided with a set of bearing rollers 63. The ends of the bearing rollers 63 are movably inserted into the roasting drum 10. The large gear ring 62 is fixedly connected to the roasting drum 10. A drive gear 64 connected to an external drive device is provided on one side of the large gear ring 62.

[0026] The mounting frame 61 has a mounting base 65 at its bottom. One end of the mounting frame 61 is hinged to the mounting base 65, and a cylinder is provided between the other end of the mounting frame 61 and the mounting base 65. The cylinder pushes the mounting frame 61 to change the stir-frying drum 10 from a horizontal state to an inclined state.

[0027] The end of the mounting rod 30 is fixed on the mounting frame 61, and the mounting rod 30 deflects synchronously with the mounting frame 61 and the frying drum 10.

[0028] Working principle: After the equipment is started, the external drive device drives the drive gear 64 to mesh with the large gear ring 62, so that the roasting drum 10 is kept rotating horizontally on the bearing support roller 63 of the mounting frame 61. The cylinder at the bottom of the mounting frame 61 initially maintains the drum horizontally. The heating module is started synchronously to control the temperature of the preheating chamber 11, the outside of the roasting chamber 12 and the inside of the expansion cylinder 40 in different zones. The preheating chamber 11 is kept at a low temperature, the roasting chamber 12 is kept at a high temperature, and the micro-cooling chamber 13 is not heated. The mounting rod 30 is fixed on the mounting frame 61 and kept statically fixed, forming a dynamic and static cooperation with the rotating roasting drum 10. The quantitative feeding mechanism 41 quantitatively supplies sesame material from the end of the expansion cylinder 40 to the preheating chamber 11. The material enters the adjacent partition plates 42 on the outer circumference of the expansion cylinder 40 and forms a thin layer. As the roasting drum 10 rotates, the material is moved along the surface of the expansion cylinder 40 by the partition plates 42. When the material moves to the middle of the expansion cylinder 40, it naturally slides to the other side due to gravity to complete the roasting action. Low-temperature uniform preheating is continuously completed in the preheating chamber 11. During this process, the material is always thinly spread without accumulation. The preheating effect is ensured by the coordinated heating inside and outside the expansion cylinder 40. An external drive unit drives the moving rod 58 to reciprocate inside the mounting rod 30. The moving rod 58 simultaneously drives the first rack 52 and the second rack 53 to move. Because there is a positional difference between the second rack 53 and the first rack 52, the second rack 53 first meshes with the second gear 55 to push it to rotate. The rotating shaft 56 in the partition plate 20 between the roasting chamber 12 and the micro-cooling chamber 13 drives the tilting plate 51 to deflect under the cooperation of the ratchet mechanism 57, so that the channel between the two chambers is opened. The material that has completed high-temperature roasting in the roasting chamber 12 smoothly enters the unheated micro-cooling chamber 13 and completes natural micro-cooling with the rotation of the drum, avoiding scorching due to residual heat. After the second rack 53 leaves the position of the second gear 55, the torsion spring drives the rotating shaft 56 to reset and close the channel. Then the first rack 52 contacts the first gear 54 and pushes it to rotate. The rotating shaft 56 in the partition plate 20 between the preheating chamber 11 and the frying chamber 12 drives the tilting plate 51 to deflect and open the channel. The preheated material in the preheating chamber 11 enters the frying chamber 12 in an orderly manner. Under high temperature environment, with the rotation of the drum and the cooperation of the partition plate 42 and the expansion cylinder 40, uniform high temperature frying is completed. The material is transferred in a unidirectional and orderly manner according to the sequence of preheating, frying and micro-cooling, without mixing and cross-temperature problems. All frying processes are completed continuously inside the frying drum 10. After the sesame seeds have completed the entire roasting process, the external cylinder pushes the hinge end of the mounting frame 61 and the mounting base 65 to deflect, causing the roasting drum 10 to change from a horizontal state to an inclined state. The mounting rod 30 deflects synchronously with the mounting frame 61 to ensure that the relative position of the internal structure remains unchanged. The roasted sesame material is quickly discharged from the discharge port along the inclined direction of the roasting drum 10 under the action of gravity. After the discharge is completed, the cylinder resets to restore the drum to a horizontal state. The entire process does not require manual transfer of materials, realizing a continuous operation from quantitative feeding, zoned temperature control roasting to automatic discharge.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.

6. The sesame roasting apparatus for sesame oil production according to claim 5, characterized in that, The mounting frame (61) has a mounting base (65) at its bottom. One end of the mounting frame (61) is hinged to the mounting base (65), and a cylinder is provided between the other end of the mounting frame (61) and the mounting base (65). The cylinder pushes the mounting frame (61) to make the stir-frying drum (10) change from a horizontal state to an inclined state.

7. The sesame roasting apparatus for sesame oil production according to claim 5, characterized in that, The end of the mounting rod (30) is fixed on the mounting frame (61), and the mounting rod (30) deflects synchronously with the mounting frame (61) and the frying drum (10).

8. The sesame roasting apparatus for sesame oil production according to claim 1, characterized in that, It also includes a heating module located outside the preheating chamber (11) and the frying chamber (12), and inside the expansion cylinder (40).

9. The sesame roasting method for sesame oil production using the sesame roasting apparatus according to any one of claims 1-8, characterized in that, Includes the following steps: S1. Start the rotation drive structure of the roasting drum (10) to keep the roasting drum (10) rotating at a constant speed. Then, through the quantitative feeding mechanism (41) installed at the end of the expansion cylinder (40), quantitative sesame material is supplied to the preheating chamber (11) of the roasting drum (10). The material enters between two adjacent partition plates (42) on the outer circumference of the expansion cylinder (40) to form a thin layer of material. S2. As the stir-frying drum (10) continues to rotate, the separator (42) drives the thinly spread material to move along the surface of the expansion cylinder (40). When the material moves to the middle position of the expansion cylinder (40), the material naturally moves to the other side of the expansion cylinder (40) due to gravity, completing one stir-frying action. The material achieves low-temperature uniform preheating in the preheating chamber (11) through multiple stir-frying actions. S3. After the material in the preheating chamber (11) has been preheated, control the opening and closing component (50) to open the communication channel between the preheating chamber (11) and the frying chamber (12). As the frying drum (10) rotates, the preheated material is transferred from the preheating chamber (11) to the frying chamber (12). Then the opening and closing component (50) is reset and the channel between the preheating chamber (11) and the frying chamber (12) is resealed. S4. The material entering the frying chamber (12) rotates with the frying drum (10) to complete the high-temperature frying operation, so as to achieve full heating and cooking of the material; S5. After the material in the roasting chamber (12) has been roasted, control the opening and closing component (50) to open the communication channel between the roasting chamber (12) and the micro-cooling chamber (13). As the roasting drum (10) rotates, the roasted material is transferred from the roasting chamber (12) to the micro-cooling chamber (13). Then the opening and closing component (50) is reset and the channel between the roasting chamber (12) and the micro-cooling chamber (13) is resealed. S6. The material entering the micro-cooling chamber (13) rotates with the roasting drum (10) and is naturally micro-cooled in an environment without additional heating, thus completing the entire sesame roasting process. Then, the cooled cooked sesame seeds can be discharged from the outlet of the roasting drum (10).
