Description

Technical Field

[0001] This utility model relates to the field of coffee bean roasting technology, specifically to a high-efficiency coffee bean roasting device. Background Technology

[0002] With the improvement of living standards, coffee has become one of the beverages that people often enjoy. Coffee is made from coffee beans. Before grinding coffee beans, in order to obtain coffee flavor and better taste, it is usually necessary to process coffee beans at high temperature, so that raw coffee beans are transformed into roasted coffee beans. Among the existing coffee bean roasting technologies, such as the Chinese patent document with patent number 202121057078.9 and publication date of 2021.11.26, it discloses an efficient coffee bean roasting device, including a motor base and a worktable. The upper end of the motor base is provided with a feeding tray, and a rotating shaft is rotatably connected through the center of the motor base. The outer surface of the rotating shaft is fixedly connected with a fan blade by welding. The lower end of the motor base is connected to the center by welding a second dropping trough, and a first dropping trough is provided on one side of the second dropping trough.

[0003] The aforementioned literature describes a method involving a sorting device above the coffee bean roaster. Coffee beans are placed into a feeding tray with different sized feeding holes on either side. A rotating fan blade pushes the beans into different roasting chambers based on their size. However, it doesn't explain how the different roasting chambers efficiently process the coffee beans at high temperatures. Existing roasting chambers tend to produce uneven roasting of small beans. Efficient and thorough high-temperature processing of coffee beans can accelerate the roasting process, thereby improving coffee production efficiency while ensuring the flavor and taste of the coffee. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency coffee bean roasting device that can effectively process coffee beans at high temperatures, resulting in good heating effect and accelerating the coffee bean roasting process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency coffee bean roasting device, comprising a cylinder and an air inlet, a heating component and an air outlet, wherein the top of the air inlet is provided with a driving air source, the bottom of the air inlet is detachably connected to the cylinder, a first ventilation cavity is formed between the air outlet and the cylinder, the heating component is disposed at the lower end of the air inlet, the air outlet is disposed at the lower end of the heating component, the air outlet is provided with two or more supports distributed along the circumference, an air outlet is formed between the supports and inclined outward in the radial direction relative to the support portion disposed on the air outlet, a second ventilation cavity is formed between the supports and the support portion, and the first ventilation cavity is connected to the second ventilation cavity through the air outlet.

[0006] The above setup, with the air source driven by the air inlet blowing into the cylinder, allows the air to pass through the heating element inside the cylinder, forming hot air. The hot air then enters the first ventilation chamber formed between the air outlet and the cylinder along the inner wall of the cylinder. Since the first ventilation chamber is connected to the inside of the cylinder through the air outlet, the hot air enters the cylinder through the inclined air outlet, thus roasting the coffee beans in the feed container located below the cylinder and connected to the inside of the cylinder at high temperature. At the same time, since the air outlet is inclined outward relative to the radial direction of the support, the air outlet on the air outlet is arranged in a spiral direction. This allows the hot air from the first ventilation chamber to be transferred to the second ventilation chamber in a spiral manner after passing through the air outlet. The hot air then enters the feed container through the second ventilation chamber, turning and heating the coffee beans in the feed container, making the heating process of the coffee beans more uniform and accelerating the roasting process.

[0007] Furthermore, the cylinder has a convex ring inside, and the air outlet includes a support part and a support body. The heating component located inside the cylinder is fixed at the upper end of the support part, and two or more support bodies are arranged circumferentially at the lower end of the support part. After the support body abuts against the convex ring, a second ventilation cavity is formed between it and the support part.

[0008] The above setup ensures a reliable connection of the air outlet by using a support body on the air outlet and connecting the air outlet body with a convex ring on the support body cylinder.

[0009] Furthermore, the air inlet includes an installation part and an air guide part. The driving air source is installed on the installation part. The installation part is detachably connected to one end of the air guide part. The air guide part extends outward from the end connected to the installation part to the other end of the air guide part to form a trumpet shape. The inner sidewall of the air guide part forms an air guide inclined surface.

[0010] The above design allows the horn-shaped air guide to direct the air from the driving air source along the inclined air guide surface into the cylinder, thus playing a guiding role.

[0011] Furthermore, the heating assembly includes a first tray, a second tray, and two or more heating elements. Two or more first partitions and second partitions are provided between the first tray and the second tray. The first partitions are perpendicular to each other on the second tray. The second partitions on the second tray are spaced apart from the first partitions. The heating elements are disposed between the first tray and the second tray and are arranged circumferentially on the second tray.

[0012] The above configuration allows the first partition and the second partition to be installed on the second tray respectively, and the first tray to be installed on the first partition and the second partition. Through the action of the first partition and the second partition, the heating element can be accommodated between the first tray and the second tray after the first tray and the second tray are assembled into a whole.

[0013] Furthermore, the first partition plate has a first protrusion on the side near the first support plate, the first partition plate has a second protrusion on the side near the second support plate, the second partition plate has a third protrusion on the side near the first support plate, and the second partition plate has a fourth protrusion on the side near the second support plate. The first support plate is provided with a first limiting hole that matches the first and third protrusions, and the second support plate is provided with a second limiting hole that matches the second and fourth protrusions.

[0014] The above configuration facilitates the installation of the first partition and the second partition on the first support plate via the first protrusion and the third protrusion, respectively. After the first partition and the second partition are installed on the first support plate, the second support plate can be installed above the first partition and the second partition via the second limiting hole. This ensures that the first partition and the second partition located between the first support plate and the second support plate are both perpendicular to the first support plate and the second support plate.

[0015] Furthermore, the first support plate is provided with a first circular hole, a first guide sleeve, and two or more first through holes. The first circular hole is located at the center of the first support plate, the first guide sleeve is symmetrically arranged on both sides of the first circular hole, and the first through holes are arranged circumferentially outside the first circular hole. The second support plate is provided with a second guide tube that matches the first guide sleeve and two or more second through holes. The second guide tube has a hollow structure, and the second through holes are located at positions corresponding to the heating element.

[0016] The above configuration allows the second tray to be installed on the first tray, and the first guide sleeve and the second guide tube can be fitted together to provide guidance for installation. By setting different first round holes and first through holes on the first tray and a second through hole on the second tray, the contact area between the air and the heating element can be increased, resulting in higher efficiency in generating hot air.

[0017] Furthermore, after the second guide tube is sleeved on the first guide sleeve, the fastener passes through the first guide sleeve and fixes the second support plate to the upper end of the support part. The support body set at the lower end of the support part is set perpendicular to the support part.

[0018] The above configuration facilitates the fixing of the heating component to the support using fasteners, ensuring it is completely located within the cylinder.

[0019] Furthermore, the two sides of the air outlet formed by two adjacent supports are arranged parallel to each other, the distance from the inner side of the two adjacent supports to the center of the support is equal, and the distance from the outer side of the two adjacent supports to the center of the support is equal and arranged along the outer side of the support.

[0020] The above configuration allows the support bodies mounted on the support portion to be spirally arranged in the same direction.

[0021] Furthermore, the two sides of the air outlet include a first side and a second side. The angle between the first side and the second side on the same support body is in the range of 22°~30°. The intersection of the first side and the inner side of the support body forms a first connecting collinearity. The angle between the plane formed by the first connecting collinearity and the central axis of the support body and the first side is in the range of 120°~130°. The intersection of the second side and the inner side of the support body forms a second connecting collinearity. The angle between the plane formed by the second connecting collinearity and the central axis of the support body and the second side is in the range of 110°~120°.

[0022] The above settings allow each air outlet to have a different airflow direction, but all airflow is directed in the same direction. This allows the hot air from the outlet to be blown in a spiral motion towards the feed container below the cylinder, thereby turning the coffee beans and accelerating the heating process.

[0023] Furthermore, the convex ring is disposed on the inner side wall of the cylinder body, the upper end face of the convex ring forms a first step surface, the support body abuts against the first step surface, the lower end face of the convex ring forms a second step surface, after the material barrel is inserted into the cylinder body, the material barrel abuts against the second step surface, and the second ventilation cavity communicates with the inside of the material barrel.

[0024] The above configuration allows hot air from the first ventilation chamber to enter the second ventilation chamber through the air outlet, and then enter the material barrel from the lower end of the cylinder body to roast the coffee beans. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-6 As shown, this utility model provides a high-efficiency coffee bean roasting device, including an air inlet, a heating component, a cylinder 1, and an air outlet. The top of the air inlet is equipped with a driving air source, and the bottom of the air inlet is detachably connected to the cylinder 1. The air inlet includes a mounting part 2 and a guide part 3. The driving air source (not shown in the figure) is mounted on the mounting part 2. The mounting part 2 and one end of the guide part 3 are detachably connected by a thread. The guide part 3 extends outward from the end connected to the mounting part 2, forming a trumpet shape. The inner wall of the guide part 3 forms a guide inclined surface 4, allowing the trumpet-shaped guide part 3 to guide the air from the driving air source along the guide inclined surface 4 into the cylinder 1, thus providing a guiding function. In this embodiment, the driving air source is a fan, which is existing technology and will not be described further.

[0033] The cylinder 1 has a protruding ring 5 inside. The protruding ring 5 is located on the inner side wall of the cylinder 1. The upper end face of the protruding ring 5 forms a first step surface 6, and the lower end face of the protruding ring 5 forms a second step surface 7. The air outlet body located inside the cylinder 1 abuts against the first step surface 6 and forms a first ventilation cavity 8 between it and the cylinder 1. The air outlet body includes a support part 9 and a support body 10. The heating component located in the first ventilation cavity 8 is fixed to the upper end of the support part 9.

[0034] like Figure 2 and Figure 3As shown, the heating assembly includes a first support plate 11, a second support plate 12, and two or more heating elements 13. Two or more first partitions 14 and second partitions 15 are provided between the first support plate 11 and the second support plate 12. In this embodiment, there are two first partitions 14 and four second partitions 15. The two first partitions 14 are perpendicularly arranged on the second support plate 12. Each of the two first partitions 14 has an opening 16 at its center that matches the thickness of the first partition 14, allowing the two first partitions 14 to interlock. Within the opening 16, for better stability, second partitions 15 are spaced apart between the first partitions 14 on the second support plate 12. Heating elements 13 are positioned between the first support plate 11 and the second support plate 12 and are circumferentially arranged on the second support plate 12. A first protrusion 17 is provided on the side of the first partition plate 14 near the first support plate 11, and a second protrusion 18 is provided on the side of the first partition plate 14 near the second support plate 12. A third protrusion 19 is provided on the side of the second partition plate 15 near the first support plate 11. A fourth protrusion 20 is provided on the side near the second support plate 12. The first support plate 11 is provided with first limiting holes 21 that match the first protrusion 17 and the third protrusion 19. The second support plate 12 is provided with second limiting holes 22 that match the second protrusion 18 and the fourth protrusion 20. Thus, by having the first protrusion 17 and the third protrusion 19 engage with the first limiting holes 21 respectively, the first partition plate 14 and the second partition plate 15 can be installed on the first support plate 11. Simultaneously, the gaps between the multiple heating coils on the heating element 13 are secured to the first support plate 14. On the partition 14 and the second partition 15, the second protrusion 18 and the fourth protrusion 20 respectively cooperate with the second limiting hole 22 to install the second support plate 12 on the first partition 14 and the second partition 15. This allows the first support plate 11 and the second support plate 12 to be assembled into a single unit through the limiting effect of the first partition 14 and the second partition 15. After assembly, the first partition 14 and the second partition 15 located between the first support plate 11 and the second support plate 12 are both perpendicular to the first support plate 11 and the second support plate 12. In this embodiment, the heating element 13 is a heating wire.

[0035] The first support plate 11 is provided with a first circular hole 23, a first guide sleeve 24, and two or more first through holes 25. The first circular hole 23 is located at the center of the first support plate 11. The first guide sleeves 24 are symmetrically arranged on both sides of the first circular hole 23. The first guide sleeves 24 are hollow. The first through holes 25 are arranged circumferentially outside the first circular hole 23. The second support plate 12 is provided with a second guide tube (not shown in the figure) that matches the first guide sleeve 24 and two or more second through holes 26. The second through holes 26 are located at positions corresponding to the heating element 13. In this way, when the second support plate 12 is installed on the first support plate 11, the first guide sleeve 24 and the second guide tube can be fitted together to play a guiding role, which facilitates installation. By providing different first circular holes 23 and first through holes 25 on the first support plate 11 and second through holes 26 on the second support plate 12, the contact area between the air and the heating element 13 can be increased, making the efficiency of hot air formation higher. In this embodiment, after the second guide tube is sleeved on the first guide sleeve 24, the fastener passes through the first guide sleeve 24 and fixes the second support plate 12 on the upper end of the support part 9. The support body 10 set at the lower end of the support part 9 is set perpendicular to the support part 9, so that the heating component can be fixed on the support part 9 by fasteners and is completely located inside the cylinder 1. The fasteners are bolts.

[0036] There are two or more support bodies 10. In this embodiment, there are 15 support bodies 10. The support bodies 10 are arranged circumferentially at the lower end of the support portion 9. After the support body 10 abuts against the first step surface 6, a second ventilation cavity 27 is formed between it and the support portion 9. An air outlet 28 is formed between adjacent support bodies 10, which is inclined outward relative to the radial direction of the support portion 9. The two sides of the air outlet 28 formed by the adjacent support bodies 10 are parallel to each other. The two sides of the air outlet 28 include a first side 29 and a second side 30. The distance from the inner side of the adjacent support body 10 to the center of the support portion 9 is equal. The distance from the outer side of the adjacent support body 10 to the center of the support portion 9 is equal and is arranged along the outer side of the support portion 9. The first side 29 and the second side 30 on the same support body 10 are not parallel to each other and form an angle α. The angle α ranges from 22° to 30°. In this embodiment, angle α is 24°. The intersection of the first side surface 29 and the inner side surface 31 of the support body forms a first connecting collinearity. The plane 32 formed by the first connecting collinearity and the central axis of the support 9 forms an angle b between the first side surface 29 and the plane 32. The angle b ranges from 120° to 130°. In this embodiment, the angle b is 124°. The intersection of the second side surface 30 and the inner side surface 31 of the support body forms a second connecting collinearity. The plane 33 formed by the second connecting collinearity and the central axis of the support 9 forms an angle c between the second side surface 30 and the plane 33. The angle c ranges from 110° to 120°. In this embodiment, the angle c is 115°. This allows each air outlet 28 to have a different air outlet direction, but all air outlets are pointing in the same direction. In this way, the hot air after passing through the air outlet 28 can be blown in a spiral manner towards the material bucket 55 below the cylinder 1, thereby turning the coffee beans and accelerating the heating process of the coffee beans.

[0037] The first ventilation chamber 8 is connected to the second ventilation chamber 27 through the air outlet 28. After the material barrel 55 is inserted into the inside of the cylinder 1, the material barrel 55 abuts against the second step surface 7. The second ventilation chamber 27 is connected to the inside of the material barrel 55, so that the hot air from the first ventilation chamber 8 can enter the second ventilation chamber 27 through the air outlet 28, and then enter the inside of the material barrel 55 from the lower end of the inside of the cylinder 1 to roast the coffee beans.

[0038] In this embodiment, a third through hole (not shown in the figure) and a fourth through hole 44 are provided on the outer side of the cylinder 1. The second ventilation cavity 27 is connected to the outside through the third through hole, so that after the hot air roasts the coffee beans, some of the hot air can be discharged to avoid excessive pressure inside the second ventilation cavity 27. The fourth through hole 44 is connected to the first ventilation cavity 8, so that the heating element 13 can be electrically connected to the outside through the fourth through hole 44, thereby enabling the heating element 13 to generate heat.

[0039] In this embodiment, the convex ring 5 is provided with a fifth through hole (not shown in the figure), so that the support body 10 abutting against the convex ring 5 can be fixed by fasteners passing through the fifth through hole, so as to prevent the force generated on the support body 10 when hot air passes through the air outlet 28 from causing the air outlet body to be misaligned inside the cylinder 1.

[0040] The working principle of this utility model is as follows: the driving air source on the air inlet blows into the cylinder 1, so that the air passing through the heating component set inside the cylinder 1 forms hot air. The hot air enters the first ventilation cavity 8 formed between the air outlet and the cylinder 1 along the inner side wall of the cylinder 1, and then enters the cylinder 1 through the air outlet 28. In this process, since the air outlet 28 is inclined outward relative to the radial direction of the support part 9, and each air outlet 28 has a different air outlet direction and is spirally arranged in the same direction, the hot air in the first ventilation cavity 8 is transferred to the second ventilation cavity 27 in a spiral manner after passing through the air outlet 28. Then, the hot air can enter the material barrel 55 through the second ventilation cavity 27, turning the coffee beans in the material barrel 55, so that the heating process of the coffee beans is more uniform, thereby accelerating the roasting process of coffee beans.
