Description

Technical Field

[0001] This disclosure relates to the field of coffee bean roasting technology, and in particular to a visual roasting mechanism and a coffee bean roaster. Background Technology

[0002] In existing technology, green coffee beans are usually placed in a roaster and roasted until the color of the coffee beans changes and they emit a coffee aroma. In order to observe the color change of the coffee beans, a window is usually added to observe the coffee beans in real time.

[0003] For example, the existing patent CN209090010U discloses a coffee roaster that uses a method where half of the drum is directly heated by a heating device, and the other half uses a hot air fan to heat the air through the heating device and then bring it into the drum to roast the coffee beans. Furthermore, the existing patent also discloses the following embodiment: a bean viewing window is provided on the lower side of the bean feeding device to observe the appearance of the coffee beans.

[0004] However, the bean viewing window is only located on the lower side of the bean feeding device, so it can only see the surface changes of the coffee beans located on the lower side of the bean feeding device. It cannot observe the coffee beans in other positions, thus making it impossible to observe the surface changes of the coffee beans globally, that is, it is impossible to observe the condition of the coffee beans in each position. Utility Model Content

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] Please see Figures 1 to 4 This is a visual bean roasting mechanism 10 according to an embodiment of the present invention, comprising a housing 100, a mounting platform 200, a roller assembly 300, and a viewing window 400. The housing 100 has a rotating shaft groove 101, a rotating shaft hole 102, a roasting cavity 103, and a viewing window 104. The roasting cavity 103 is connected to the rotating shaft groove 101, the rotating shaft hole 102, and the viewing window 104 respectively. The mounting platform 200 is disposed on the housing 100. The roller assembly 300 includes a roller body 310, a stirring component 320, and a reduction motor 330. A geared motor 330 is mounted on the mounting platform 200. A portion of the stirring component 320 and the drum body 310 are located in the roasting chamber 103. The stirring component 320 also passes through the shaft hole 102. One end of the stirring component 320 is connected to the drive end of the geared motor 330, and the other end abuts against the shaft groove 101. The stirring component 320 is also connected to the inner wall of the drum body 310. A viewing window 400 is mounted on the viewing window 104 to allow for global observation of the surface changes of the coffee beans. Furthermore, the edge of the viewing window 104 coincides with the side wall of the drum body 310, allowing the user to observe the internal structure of the drum assembly 300 and the surface changes of the coffee beans during roasting.

[0030] In this embodiment, the drum body 310 has an inner cavity, and the shaft groove 101, shaft hole 102 and viewing window 104 are all in communication with the inner cavity. Part of the structure of the stirring component 320 is located in the inner cavity.

[0031] In the above embodiments, the visual roasting mechanism 10 uses a viewing window 400, which is installed in the viewing window 104. The user can view the structure inside the drum assembly 300 with their eyes. After the green coffee beans are put into the drum body 310, the roasting process begins. Then, the user can observe the roasting process of the coffee beans with their eyes to observe the coffee beans as a whole and confirm whether the appearance of the coffee beans meets the user's expectations for the appearance of the coffee beans. In this way, the design of the viewing window 400 enables the overall mechanism to have good visibility.

[0032] It's understandable that after removing the 400mm viewing window, the result is as shown in the image. Figure 2 As shown, this verifies the authenticity of the user's global observation of the coffee beans during roasting.

[0033] Furthermore, combined Figure 2 and Figure 3 As shown, the stirring component 320 includes a rotating shaft 321 and a stirring rod 322. Both the rotating shaft 321 and the stirring rod 322 are located in the baking chamber 103. The rotating shaft 321 passes through the rotating shaft hole 102. One end of the rotating shaft 321 is connected to the drive end of the reduction motor 330, and the other end of the rotating shaft 321 abuts against the rotating shaft groove 101. One end of the stirring rod 322 is fixedly connected to the rotating shaft 321, and the other end of the stirring rod 322 is fixedly connected to the inner wall of the drum body 310.

[0034] In this embodiment, part of the structure of the rotating shaft 321 and the stirring rod 322 are located in the inner cavity of the drum body 310.

[0035] like Figures 1 to 3 As shown, in one embodiment, the viewing window 400 includes a first half-viewing window 410 and a second half-viewing window 420, and the viewing window 104 includes a first viewing window 1041 and a second viewing window 1042. Both the first viewing window 1041 and the second viewing window 1042 are connected to the roasting chamber 103. The first half-viewing window 410 is installed in the first viewing window 1041, and the second half-viewing window 420 is installed in the second viewing window 1042. The edge portions of the first viewing window 1041 and the edge portions of the second viewing window 1042 are both aligned with the sidewall of the drum body 310. Thus, the user can observe the structure of the drum assembly 300 through the first viewing window 1041 and / or the second viewing window 1042, and can also observe the changes in the appearance of the coffee beans globally through the first viewing window 1041 and / or the second viewing window 1042 during the roasting process. Furthermore, the first viewing window 1041 and the second viewing window 1042 are symmetrically arranged; and the first half-viewing window glass 410 and the second half-viewing window glass 420 are symmetrically arranged.

[0036] In this embodiment, both the first viewing window 1041 and the second viewing window 1042 are connected to the inner cavity of the roller body 310.

[0037] Furthermore, the spatial area of ​​the first viewing window 1041 is equal to the spatial area of ​​the second viewing window 1042, so that the first viewing window 1041 and the second viewing window 1042 have the same specifications and are symmetrically arranged. Even further, the cross-sectional area of ​​the first half-viewing window glass 410 is equal to the cross-sectional area of ​​the second half-viewing window glass 420, so that the first half-viewing window glass 410 and the second half-viewing window glass 420 have the same specifications and are symmetrically arranged.

[0038] Furthermore, the first viewing window 1041 and the second viewing window 1042 are spaced apart on the same side of the housing 100.

[0039] like Figure 3 or Figure 4 As shown, in one embodiment, the drum body 310 has multiple sieve holes 311, which are distributed around the sidewall of the drum body 310. In this embodiment, the green coffee beans have a silver skin. When the coffee beans are roasted to a certain temperature, the silver skin falls off. As the drum body 310 rotates, the sieve holes 311 are used to remove the silver skin, effectively removing it and preserving the roasted coffee beans. Further, as... Figure 3 As shown, the drum assembly 300 also includes a silver shavings collection box 340, which is detachably installed in the housing 100 and located within the roasting chamber 103, below the drum body 310. Thus, after the silver shavings are removed, they fall into the silver shavings collection box 340, which collects the silver shavings that have fallen from the coffee beans, allowing for their reuse.

[0040] Furthermore, such as Figure 2 As shown, the roller assembly 300 also includes a guide baffle 350, which is located within the baking cavity 103 and connected to the housing 100. The guide baffle 350 is positioned between the roller body 310 and the silver sheet receiving box 340. It can be understood that when sieving out fallen silver sheets, some silver sheets fall directly into the silver sheet receiving box 340 through the sieve holes 311 in the middle of the roller body 310, while some silver sheets fall through the sieve holes 311 at the edge of the roller body 310. In this case, the silver sheets first fall into the guide baffle 350 and then gradually slide along the guide baffle 350 into the silver sheet receiving box 340. This ensures that the silver sheets located at the edge of the roller body 310 can fall into the silver sheet receiving box 340, allowing for better utilization of the silver sheets. Furthermore, the guide baffle 350 is located on the outer side of the roller body 310.

[0041] In one embodiment, such as Figure 2 and Figure 3As shown, the visible coffee roasting mechanism 10 also includes a sampling spoon 500, and the housing 100 is provided with a sampling port 105, which communicates with the roasting chamber 103. The sampling spoon 500 passes through the sampling port 105 and abuts against the housing 100. It can be understood that during the coffee bean roasting process, the user can use the sampling spoon 500 to collect a small amount of coffee beans to observe their current condition. Specifically, when the tip of the sampling spoon 500 penetrates into the drum body 310, some coffee beans fall onto the tip. The sampling spoon 500 is then removed to observe the current condition of the coffee beans. Thus, the sampling spoon 500 is designed to collect coffee beans during the roasting process for observation of their current appearance.

[0042] In this embodiment, the sampling port 105 and the viewing window 104 are offset and located on the same side of the housing 100.

[0043] Furthermore, the sampling port 105 is connected to the inner cavity of the roller body 310.

[0044] In one embodiment, the geared motor 330 is a stepper motor or a servo motor. In this embodiment, the geared motor 330 can be a stepper motor.

[0045] This disclosure also provides a coffee bean roaster, including the visible roasting mechanism 10 of any of the above embodiments.

[0046] Compared with the prior art, this disclosure has at least the following advantages:

[0047] The aforementioned visual roasting mechanism 10 uses a viewing window 400, which is installed in the viewing window 104. Users can observe the structure inside the drum assembly 300 with their own eyes. After the green coffee beans are placed into the drum body 310, the roasting process begins. Users can then observe the roasting process of the coffee beans with their own eyes to get a global view of the coffee beans and confirm whether the appearance of the coffee beans meets the user's expectations. Thus, the design of the viewing window 400 enables the entire mechanism to have good visibility.

[0048] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
