Description

Technical Field

[0001] This invention relates to the field of coffee bean production technology, specifically to an energy-saving production line and preparation method for coffee bean production. Background Technology

[0002] Coffee bean roasting is a crucial step in coffee production. The process involves heating the green beans to induce the Maillard reaction, which develops their unique flavor and aroma. Rotary roasting is one of the mainstream technologies currently available. It uses a rotating drum to ensure the coffee beans are heated and tumbled evenly in hot air, preventing localized overheating or uneven roasting.

[0003] Most existing roasting equipment uses fixed stirring blades or static liner structures. For example, a coffee roaster with patent number CN201910123456.7 has a fixed liner on the inner wall of its cylinder, which drives the coffee beans to rise and fall by rotating.

[0004] However, this type of equipment has significant shortcomings: First, the fixed liner has limited effect on turning the coffee beans during the rotation of the cylinder, easily creating "dead zones" within the beans and leading to uneven heating. Second, due to the low turning efficiency, to achieve the ideal roasting effect, it is often necessary to extend the roasting time or increase the heating temperature, resulting in increased energy consumption, which is inconsistent with the trend of energy conservation. In addition, some equipment attempts to use complex stirring mechanisms, but these are structurally complex, costly to manufacture, and difficult to operate stably in high-temperature environments.

[0005] Therefore, there is an urgent need in this field for an energy-saving production line that improves stir-frying efficiency and reduces energy consumption by using a dynamic liner structure on the basis of rotary baking. Summary of the Invention

[0006] This invention provides an energy-saving production line and preparation method for coffee bean production, which features automatic extension and oscillation of the liner during the rotation of the cylinder, significantly improving the uniformity of coffee bean roasting, thereby achieving the beneficial effect of energy-saving and efficient roasting, and solving the problems mentioned in the background art.

[0010] As an optional embodiment of the energy-saving production line for coffee bean production described in this invention, the guide groove includes a first arc segment and a second arc segment that are interconnected, wherein the radius of the first arc segment is greater than the radius of the second arc segment.

[0013] As an optional embodiment of the energy-saving production line for coffee bean production described in this invention, the second control component includes several second fixed frames that are respectively fixedly installed on several first fixed frames, rotating rods that are rotatably installed on several second fixed frames, fifth gears that are fixedly installed on several rotating rods, and sixth gears that are fixedly installed on one side of several mounting seats located outside the cylinder, with several sixth gears meshing with several fifth gears respectively.

[0016] The present invention also provides the following technical solution: a method for preparing an energy-saving production line for coffee bean production, comprising the following steps: after coffee beans are fed into the cylinder through the feed inlet, the axial flow impeller and the cylinder are rotated counterclockwise by a motor. The rotation of the axial flow impeller evenly conducts the heat generated by the heating wire to the inside of the oven to roast the coffee beans. At the same time, during the counterclockwise rotation of the cylinder, several second liner plates extend and reciprocate when rotating to the right side to stir the coffee beans.

[0017] The present invention has the following beneficial effects: 1. This energy-saving production line and preparation method for coffee beans utilizes a dynamic telescopic liner structure consisting of a first liner and a second liner. A first control component precisely controls the extension of the second liner when the cylinder rotates to the lower right and its retraction when rotating to the upper right, significantly increasing the lifting height and scattering force of the coffee beans. This design effectively breaks down the "dead zone" formed within the cylinder, resulting in more even heating of the beans and fundamentally improving the uniformity and consistency of roasting, thus ensuring the final quality of the coffee beans.

[0018] 2. This energy-saving production line and preparation method for coffee beans introduces a second control component, enabling the mounting base and second liner to reciprocate during the cylinder's rotation. This combined "extension" and "oscillation" motion simulates the "tossing" action of manual roasting, significantly optimizing the material's trajectory and further enhancing mixing and roasting effects. Under the same roasting effect requirements, this design can effectively shorten the required roasting time or lower the roasting temperature, thereby significantly reducing energy consumption and aligning with the energy-saving trend of green production.

[0019] 3. This energy-saving production line and method for coffee bean production utilizes a single motor to simultaneously drive the hot air circulation system, cylinder rotation, and complex liner motion. The transmission system efficiently distributes power through gear sets (first to fourth gears), while the extension and oscillation of the liner are achieved through the engagement of guide balls with guide grooves of specific contours, and the meshing of the fifth gear with alternating external / internal gear rings. The entire system is highly integrated and compact, achieving energy savings while improving roasting performance. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, please refer to Figures 1-10 An energy-saving production line for coffee bean production includes an oven 100, a heating mechanism 200 and a feed cylinder 300. The heating mechanism 200 includes a heating wire 210 and a motor 220 fixedly installed inside the oven 100. An axial flow impeller 230 is fixedly installed on the output shaft of the motor 220. An air guide shroud 240 is fixedly installed inside the oven 100, and the axial flow impeller 230 is rotatably connected to the air guide shroud 240.

[0033] The material cylinder 300 includes a cylinder body 310 rotatably installed inside the oven 100, with a material inlet 320 on the cylinder body 310. An outer cylinder 110 is fixedly installed on the oven 100. Both the outer cylinder 110 and the cylinder body 310 have several air holes 330. A rotating shaft 340 is rotatably installed inside the oven 100. A first gear 350 is fixedly installed on the rotating shaft 340. A second gear 360 is fixedly installed on the cylinder body 310. The first gear 350 meshes with the second gear 360.

[0034] A third gear 370 is fixedly mounted on the output shaft of the motor 220, and a fourth gear 380 is fixedly mounted on the rotating shaft 340. The third gear 370 and the fourth gear 380 mesh.

[0035] The cylinder 310 is also provided with a stirring mechanism 400, which includes a number of mounting seats 420 fixedly installed on the cylinder 310. A first liner 430 is fixedly installed on each of the mounting seats 420, and a second liner 440 is slidably installed inside each of the first liner 430.

[0036] The stir-frying mechanism 400 also includes a first control component 450, which controls the second liner 440 to extend outward from the first liner 430 when the cylinder 310 rotates counterclockwise to the lower right side, and controls the second liner 440 to retract inward from the first liner 430 when the cylinder 310 rotates counterclockwise to the upper right side, so as to stir-fry the coffee beans.

[0037] In this embodiment: After coffee beans are placed into the cylinder 310 through the feed port 320, the heating wire 210 and the motor 220 are started. The heating wire 210 generates heat through resistance heating. The output shaft of the motor 220 rotates counterclockwise, which drives the axial flow fan 230 to rotate. The axial flow fan 230 and the air guide shroud 240 constitute the structure of a circulating fan in the prior art, which can evenly conduct the heat generated by the heating wire 210 to all parts of the oven 100 in the form of hot air.

[0038] On the other hand, the output shaft of the motor 220 drives the third gear 370 to rotate counterclockwise, which in turn drives the fourth gear 380, the rotating shaft 340 and the first gear 350 to rotate clockwise. The first gear 350 drives the second gear 360 and the cylinder 310 to rotate counterclockwise.

[0039] by Figure 1 Using the front, back, left, and right directions as a reference, the cylinder 310 rotates counterclockwise along its central axis. Under the action of centrifugal force and friction on the inner wall of the cylinder 310, the coffee beans are thrown up from the lower inner wall of the cylinder 310 to the upper right. After reaching the highest point on the upper right, the coffee beans fall to the lower left. The rotation of the cylinder 310 can be used to stir-fry the coffee beans.

[0040] To further improve the stir-frying effect, a stir-frying mechanism 400 is also provided. The liner structure of the stir-frying mechanism 400 consists of two parts: a mounting base 420 and a second liner 440. The mounting base 420 is installed on the inner wall of the cylinder 310, and the second liner 440 is slidably installed on one side of the mounting base 420 inside the cylinder 310, forming a telescopic liner structure.

[0041] The first control component 450 ensures that the second liner 440 is in a contracted state during the process of moving counterclockwise from the upper right side to the lower right side of the circular motion trajectory as it moves with the cylinder 310, thus not affecting the effective volume of the cylinder 310.

[0042] As the coffee beans are tossed up to the upper right and then fall to the lower left, the second liner 440 moves counterclockwise from the lower right side of the circular trajectory to the upper right side, where it is in an extended state. The extended second liner 440 can carry the coffee beans to a higher angle on the upper right side, thereby increasing the force of roasting the coffee beans.

[0043] Example 2, please refer to Figures 1-10 The first control component 450 includes a plurality of lifting rods 451 that are slidably mounted on a plurality of mounting seats 420. A plurality of first fixing frames 452 are fixedly mounted on the outer side of the cylinder 310. Guide rods 455 are slidably mounted on each of the plurality of first fixing frames 452. The plurality of guide rods 455 are fixedly connected to the plurality of lifting rods 451 respectively.

[0044] Guide balls 456 are fixedly installed on several guide rods 455, and guide grooves 457 are opened on the inner wall of the outer cylinder 110. Several guide balls 456 are slidably disposed in the guide grooves 457.

[0045] The guide groove 457 includes a first arc segment 4571 and a second arc segment 4572 that are interconnected, and the radius of the first arc segment 4571 is greater than the radius of the second arc segment 4572.

[0046] Several lifting rods 451 are provided with arc-shaped sliding grooves 453, and several guide rods 455 are fixedly installed with sliders 454. Several sliders 454 are slidably connected to several arc-shaped sliding grooves 453 respectively.

[0047] In this embodiment: a lifting rod 451 is slidably installed on the other side of the mounting base 420. The lifting rod 451 extends through the surface of the mounting base 420 and is connected to a guide rod 455 on the lower side of the lifting rod 451. The first fixing frame 452 is installed on the outer wall of the cylinder 310, and the guide rod 455 is slidably installed on the first fixing frame 452, and the sliding direction is the radial direction of the cylinder 310.

[0048] A guide ball 456 is installed at the end of the guide rod 455, such as Figure 6 As shown, the guide groove 457 is in cross-section with the guide rod 455 and the guide ball 456, and in profile, the first arc segment 4571 and the second arc segment 4572 are smoothly transitioned.

[0049] When the cylinder 310 rotates, causing a second liner 440 to reach the lower connection between the first arc segment 4571 and the second arc segment 4572, the guide ball 456 and the guide rod 455 will slide along the radial direction of the cylinder 310 toward the center of the cylinder 310, thereby driving the lifting rod 451 and the second liner 440 to move toward the center of the cylinder 310, and the second liner 440 will extend.

[0050] As the cylinder 310 continues to rotate counterclockwise, the guide ball 456 passes through the upper connection between the first arc segment 4571 and the second arc segment 4572, and enters the first arc segment 4571 from the second arc segment 4572. At this time, the guide ball 456 will drive the second liner 440 to move away from the center of the cylinder 310, and the second liner 440 will shorten.

[0051] Setting the guide ball 456 to be a ball wider than the guide rod 455 serves to smooth the guiding process and to limit movement.

[0052] Example 3, please refer to Figures 1-10 The cylinder 310 has several rotating slots 410, and several mounting seats 420 are rotatably installed in the several rotating slots 410.

[0053] The stir-frying mechanism 400 also includes a second control component 460, which controls the mounting base 420 and the second liner 440 to reciprocate as the cylinder 310 rotates counterclockwise to stir the coffee beans.

[0054] The second control component 460 includes several second fixed frames 461 that are fixedly mounted on several first fixed frames 452 respectively. Each of the several second fixed frames 461 has a rotating rod 462 rotatably mounted on it. Each of the several rotating rods 462 has a fifth gear 463 fixedly mounted on it. Each of the several mounting seats 420 has a sixth gear 464 fixedly mounted on one side outside the cylinder 310. Each of the several sixth gears 464 meshes with each of the several fifth gears 463 respectively.

[0055] Two external gear rings 465 and two internal gear rings 466 are fixedly installed inside the outer cylinder 110. The two external gear rings 465 and two internal gear rings 466 are arranged alternately, and both the two external gear rings 465 and the two internal gear rings 466 are adapted to the fifth gear 463.

[0056] The second control component 460 also includes several limiting rods 467 that are fixedly installed on several rotating rods 462 respectively. A limiting groove 468 is opened on the inner wall of the outer cylinder 110, and the several limiting rods 467 are slidably connected in the limiting groove 468.

[0057] The limiting groove 468 includes a third arc segment 4681, a fourth arc segment 4682 and a fifth arc segment 4683 connected in sequence, and the widths of the third arc segment 4681, the fourth arc segment 4682 and the fifth arc segment 4683 increase in sequence.

[0058] In this embodiment, in order to further enhance the role of the second liner 440 in the process of roasting coffee beans, the following settings are also made.

[0059] First, the mounting base 420 is cylindrical and rotatably mounted on the cylinder 310. A second mounting bracket 461 is mounted on the first fixed bracket 452, and the position of the second fixed bracket 461 is also relatively fixed to the cylinder 310. The fifth gear 463 mounted on the rotating rod 462 is relatively long and can mesh with the sixth gear 464, the external gear ring 465, and the internal gear ring 466. The sixth gear 464 is mounted on the portion of the mounting base 420 located outside the cylinder 310. The sixth gear 464 is an incomplete gear and will not touch the outer wall of the cylinder 310 during the rotation of the mounting base 420.

[0060] The two external gear rings 465 and two internal gear rings 466 installed inside the cylinder 310 are both arc-shaped gear rings centered on the center of the cylinder 310. The external gear rings 465 can mesh with the outer side of the fifth gear 463, while the internal gear rings 466 can mesh with the inner side of the fifth gear 463. Due to the different meshing directions, the rotation direction of the fifth gear 463 is different. Furthermore, the two external gear rings 465 and the two internal gear rings 466 are arranged alternately. A limit rod 467 and a limit groove 468 are also provided to limit the movement of the fifth gear 463.

[0061] Specifically, when the second liner 440 rotates with the cylinder 310... Figure 7 When the third arc segment 4681 shown enters the fourth arc segment 4682, the fourth arc segment 4682 becomes wider, allowing the rectangular limiting rod 467 to rotate, while the cylinder 310 continues to rotate.

[0062] The fifth gear 463 first meshes with the lowermost external gear ring 465 and rotates counterclockwise under the drive of the external gear ring 465, thereby causing the mounting base 420 and the second liner 440 to rotate clockwise, that is, towards the inner wall of the cylinder 310. At this time, the rotating limit rod 467 is precisely restricted by the fourth arc segment 4682, minimizing its rotation.

[0063] As the cylinder 310 continues to rotate counterclockwise, the limiting rod 467 moves from the fourth arc-shaped segment 4682 into the wider fifth arc-shaped segment 4683. At this time, the fifth gear 463 meshes with the first internal gear ring 466 and rotates clockwise, causing the mounting base 420 and the second liner 440 to rotate counterclockwise. Similarly, the fifth gear 463 then meshes with the second external gear ring 465 and the second internal gear ring 466 successively, reciprocating in rotation.

[0064] Then the limiting rod 467 returns from the fifth arc segment 4683 to the third arc segment 4681. Due to the second internal gear ring 466 causing it to rotate counterclockwise to reset, it is then continued to be limited so that the second liner 440 is in the radial direction of the cylinder 310.

[0065] During the rotation of the second liner 440, the arc-shaped slide 453 with the rotating groove 410 as the center rotates relative to the slider 454, while the slider 454 and the guide rod 455 are fixed in position.

[0066] Example 4, please refer to Figures 1-8 A method for preparing an energy-saving production line for coffee bean production, including feeding and start-up: Coffee beans are fed into the cylinder 310 through the feed inlet 320.

[0067] Start heating wire 210 and motor 220.

[0068] Hot air circulation and heating: Heating wire 210 generates heat when energized.

[0069] Motor 220 drives axial flow fan 230 to rotate.

[0070] The axial fan 230 works in conjunction with the air guide 240 to blow hot air evenly into the oven 100.

[0071] Hot air passes through the air holes 330 on the outer cylinder 110 and the cylinder body 310 to roast the coffee beans inside the cylinder.

[0072] Rotating the cylinder and basic stir-frying: The output shaft of motor 220 rotates counterclockwise, driving the third gear 370 to rotate counterclockwise.

[0073] The third gear 370 drives the fourth gear 380 to rotate clockwise.

[0074] The fourth gear 380 drives the rotating shaft 340 and the first gear 350 to rotate clockwise.

[0075] The first gear 350 drives the second gear 360 and the cylinder 310 to rotate counterclockwise.

[0076] The coffee beans are lifted from the lower right side by centrifugal force and friction from the inner wall of the cylinder 310, thrown to the upper left side and then fall down, thus achieving basic roasting.

[0077] The first control component drives the liner to extend and retract for stirring: During the rotation of the cylinder 310, the guide ball 456, which is fixed to the end of the guide rod 455, slides along the guide groove 457, which is fixed to the inner wall of the outer cylinder 110.

[0078] When the second liner 440 rotates with the cylinder to the lower right side of the motion trajectory, the guide ball 456 enters the second arc-shaped section 4572 with a smaller radius in the guide groove 457.

[0079] This change forces the guide rod 455 to slide along the first fixing frame 452 toward the center of the cylinder 310.

[0080] The guide rod 455, through the cooperation of the slider 454 and the arc-shaped groove 453, pushes the lifting rod 451, causing the second liner 440 to extend outward from the inside of the first liner 430.

[0081] As the extended second liner 440 rotates from the lower right to the upper right, it carries more coffee beans to a higher position, increasing the spraying force.

[0082] When the second liner 440 rotates to the upper right side of the motion trajectory, the guide ball 456 enters the first arc-shaped segment 4571 with a larger radius in the guide groove 457.

[0083] The guide rod 455 drives the lifting rod 451 to move in the opposite direction, causing the second liner 440 to retract inward, thus avoiding affecting the effective volume of the cylinder.

[0084] The second control component drives the liner to swing and stir: When the cylinder 310 rotates, the limiting rod 467 fixed on the rotating rod 462 enters the wider fourth arc section 4682 from the third arc section 4681 of the limiting groove 468, and the limiting rod 467 gains rotation space.

[0085] Subsequently, the fifth gear 463 on the rotating rod 462 meshes with an external gear ring 465, driving the fifth gear 463 to rotate counterclockwise.

[0086] The fifth gear 463 drives the sixth gear 464 and the mounting base 420 to rotate clockwise, causing the second liner 440 to swing toward the inner wall of the cylinder.

[0087] When the limit rod 467 enters the wider fifth arc segment 4683, the fifth gear 463 meshes with an internal gear ring 466, driving the fifth gear 463 to rotate clockwise.

[0088] The fifth gear 463 drives the sixth gear 464 and the mounting base 420 to rotate counterclockwise, causing the second liner 440 to swing in the opposite direction.

[0089] By sequentially engaging with the alternating outer gear ring 465 and inner gear ring 466, the second liner 440 reciprocates during the elongation phase, simulating a "tossing" motion.

[0090] Compound motion and material discharge: The coffee beans are thoroughly and evenly roasted and mixed under the combined action of the rotation of the cylinder 310 and the periodic extension and oscillation of the second liner 440.

[0091] After roasting is complete, stop the motor 220 and heating wire 210, and remove the roasted coffee beans through the feed port 320 or a dedicated discharge mechanism.

[0092] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
