Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coffee roasting, and more particularly to a roasting urn structure. Background Technology
[0002] Raw coffee beans lack coffee aroma and must be roasted at high temperatures to evaporate the moisture and induce the Maillard reaction, thus producing coffee beans with a rich aroma.
[0003] Existing coffee bean roasters primarily consist of a rotating power source within the machine body, connected to one end of a cylindrical roasting drum to drive its rotation. A vent is formed at the other end of the drum for pouring or removing coffee beans. A heat source is located below the drum to roast the beans. However, the walls of the roasting chamber in existing roasting drums are smooth and rounded. Therefore, when the drum rotates, the coffee beans inside the chamber are difficult to move around and tend to accumulate at the bottom, resulting in the beans being constantly heated directly by the heat source. This not only causes uneven heating but also makes the beans prone to a burnt taste. Furthermore, existing roasting drums are made of stainless steel, which can release metallic toxins when heated, contaminating the coffee beans and severely damaging their quality.
[0004] Therefore, in view of the aforementioned shortcomings in the use and implementation of existing baking tins, the inventor of this case, with the assistance of his many years of manufacturing and design experience and knowledge in related fields, and through various ingenious ideas, created this utility model. Utility Model Content
[0005] This utility model relates to a roasting urn structure, the main purpose of which is to provide a roasting urn structure that allows coffee beans to be roasted evenly and heat-treated, avoiding the production of burnt flavor.
[0006] To achieve the above-mentioned objectives, a baking urn structure is provided, comprising an urn body and a cavity within the urn body. The urn body has a first end and a second end formed at opposite ends. The diameter of the urn body is larger than the diameters of the first end and the second end. An opening is provided at the first end of the baking urn, which communicates with the cavity of the baking urn. Furthermore, a plurality of flange portions and a plurality of recess portions extending from the first end to the second end are formed on the cavity wall of the cavity. The plurality of flange portions and the plurality of recess portions are arranged in a continuous and spaced manner.
[0007] The baking urn structure described above has a plurality of textures on the surface of the urn body that are relatively uneven with respect to the plurality of flange portions and the plurality of recess portions.
[0008] In the baking jar structure described above, the position of the first end of the baking jar is relatively higher than the position of the second end of the baking jar. An imaginary center line is defined passing through the center of the first end and the center of the second end, and the inclination angle of the imaginary center line is 20 degrees to 45 degrees.
[0009] The baking jar structure described above is made of clay.
[0010] In this way, when in use, coffee beans are poured from the mouth of the roasting jar into the cavity of the roasting jar and placed in the multiple recesses provided in the cavity. As the roasting jar rotates, the beans are continuously rotated and placed in different positions. The residual heat of the roasting jar itself is used to roast the coffee beans, avoiding the coffee beans being directly heated by the heat source, which can easily produce a burnt taste. In this way, the coffee beans are heated evenly, effectively improving the roasting quality of the coffee beans. Attached Figure Description

[0019] To provide a more complete and clear disclosure of the technical means and effects achieved by this utility model, please refer to the accompanying drawings and reference numerals. The details are as follows:
[0020] First, please refer to Figure 1 and Figure 2As shown, the baking urn 1 of this utility model is made of clay and mainly includes a urn body 11, with a cavity 12 provided inside the urn body 11. The urn body 11 has a first end 13 and a second end 14 formed at opposite ends. The diameter of the urn body 11 is larger than the diameters of the first end 13 and the second end 14. A urn opening 15 is provided at the first end 13 of the baking urn 1, which communicates with the cavity 12 of the baking urn 1. Furthermore, the position of the first end 13 of the baking urn 1 is relatively higher than that of the second end 14. The positions of the two ends 14 are defined, and an imaginary center line is defined passing through the center of the first end 13 and the center of the second end 14. The inclination angle of the imaginary center line is 20 degrees to 45 degrees. In addition, a plurality of flange portions 16 and a plurality of recess portions 17 extending from the first end 13 to the second end 14 are formed on the cavity wall of the cavity 12. The plurality of flange portions 16 and the plurality of recess portions 17 are arranged in a continuous interval. The surface of the urn body 11 is formed with a plurality of textures 18 that are relatively uneven with respect to the plurality of flange portions 16 and the plurality of recess portions 17.
[0021] Therefore, please refer to the following when roasting coffee beans. Figure 3 As shown, the roasting urn 1 of this utility model is assembled with a coffee bean roaster 2. The second end 14 of the roasting urn 1 is connected to the drive shaft of the rotary power source 21 of the roaster 2. The rotary power source 21 can be an electric motor. The roaster 2 is provided with a fire source 22 below the roasting urn 1. The fire source 22 can be a gas stove. The roasting urn 1 and the fire source 22 are tilted at an angle of about 20 degrees to 45 degrees. This is to increase the amount of beans fed in and to prevent coffee beans from falling out of the urn opening 15 provided at the first end 13.
[0022] Therefore, when the baking machine 2 is started, its rotational power source 21 drives the baking jar 1 to rotate counterclockwise. Meanwhile, the heat energy generated by the combustion of gas by the fire source 22 is transferred to the baking jar 1 to heat it. Once the baking jar 1 has reached the appropriate temperature, please refer to [further details omitted]. Figure 4 As shown, raw coffee beans 3 are poured into the cavity 12 of the roasting urn 1 through the opening 15 at the first end 13 of the roasting urn 1 to roast the coffee beans 3. When the roasting urn 1 rotates, the multiple recesses 17 in the cavity 12 of the roasting urn 1 that can accommodate the coffee beans 3 are carried to a higher position away from the lower heat source 22 as the roasting urn 1 rotates, and are thrown into the recesses 17 on the left and right sides by gravity. The coffee beans 3 are then roasted by the residual heat of the roasting urn 1 after it is heated.
[0023] As the roasting urn 1 rotates, the coffee beans 3 within its cavity 12 are repeatedly moved away from the lower heat source 22 and tossed to the left and right side recesses 17, resulting in even heating of the coffee beans 3. This prevents the coffee beans 3 from accumulating at the bottom of the cavity 12 of the roasting urn 1 and being continuously heated directly by the heat source below. This effectively prevents the coffee beans 3 from burning and developing a burnt flavor, thus improving the roasting quality of the coffee beans 3. Furthermore, it is worth mentioning that the roasting urn 1 of this invention is made of clay, so it will not release metallic toxins that contaminate the coffee beans 3 when heated by the heat source 22. Therefore, it can further improve the roasting quality and flavor of the coffee beans 3.
[0024] The foregoing embodiments or drawings are not intended to limit the implementation of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the protection scope of this utility model.
[0025] As can be seen from the above structure and implementation method, this utility model has the following advantages:
[0026] 1. The roasting urn structure of this utility model has multiple continuously spaced flange portions 16 and recessed portions 17 formed in the cavity 12 of the roasting urn 1. In this way, the coffee beans contained in the recessed portions 17 can be continuously turned and moved as the roasting urn 1 rotates, so as to roast the coffee beans by the residual heat of the roasting urn 1 itself, avoiding the coffee beans being directly heated by the heat source and producing a burnt taste, thereby effectively improving the roasting quality of coffee beans.
[0027] 2. The roasting urn structure of this utility model makes the roasting urn 1 tilted at an angle of about 20 degrees to 45 degrees, and the height of the first end 13 of the roasting urn 1 is relatively higher than the height of the second end 14. In this way, not only can the amount of beans be added be increased, but also the situation that coffee beans may fall out of the urn opening 15 provided at the first end 13 when the roasting urn 1 is rotated can be prevented.
[0028] 3. The roasting urn of this utility model is made of clay. Therefore, when heated by a fire source, the clay roasting urn of this utility model will not release metallic toxins and contaminate the coffee beans. Accordingly, it achieves the effect of further improving the roasting quality and drinking flavor of coffee beans.
