Description

TECHNICAL FIELD

[0001] The utility model relates to coffee bean roasting technical field, especially a coffee bean roasting device. BACKGROUND

[0002] Coffee bean roasting refers to the process of changing the color, flavor, aroma and taste of green coffee beans through heating treatment, so that a series of complex chemical changes occur inside. The roasting process not only affects the appearance and flavor of coffee beans, but also has a decisive influence on the final quality of coffee and consumer experience.

[0003] The existing coffee beans need to be roasted using a roasting device when roasting, and the roasting device is mainly divided into three types of direct fire type, semi-hot air type and hot air type. Taking the direct fire type as an example, after the coffee beans are added to the inside of the roasting device, the roller is rotated to make the coffee beans directly contact the flame at the bottom, thereby realizing the roasting of coffee beans.

[0004] The existing direct fire type roasting device usually directly adds the coffee beans needed for roasting into the inside of the roasting device through the hopper at the top when adding material, and such a large amount of coffee beans added at one time is easy to cause the accumulation of coffee beans, which is not conducive to the roaster to control the temperature in the furnace, resulting in the surface of the beans being seared, and it is relatively inconvenient to use.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] ReferenceFigure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a coffee bean roasting device, including a housing 1, a heating component 2 inside the housing 1, a feeding component 3 on the top of the housing 1, and a cooling component 4 on one side of the heating component 2.

[0032] The feeding assembly 3 includes a hopper 301 fixedly installed on the outer surface of the heating component 2. A rotating shaft 303 is movably installed inside the hopper 301 via a bearing. A rotating block 302 is installed on the outer surface of the rotating shaft 303. A rotating disk 304 is fixedly connected to the end of the rotating shaft 303 away from the heating component 2 through the outer surface of the hopper 301.

[0033] Specifically, the rotating block 302 has a semi-circular cross-section, and the hopper 301 has a cylindrical cavity with the same radius as the rotating block 302. Feed channels 309 for feeding are provided on both sides of the cylindrical cavity. By cooperating with the semi-circular rotating block 302 and the cylindrical cavity, the amount of coffee beans added to the heating element 2 at one time in the hopper 301 can be controlled. The rotation of the rotating block 302 drives the coffee beans to be fed sequentially from the feed channels 309 on both sides, avoiding the accumulation of coffee beans in one place.

[0034] Specifically, two fixed frames 305 are fixedly installed on the outer surface of the hopper 301. A movable block 307 is slidably arranged inside the fixed frame 305. The outer surface of the rotating disk 304 is provided with a slot that cooperates with the movable block 307. A spring 308 is fixedly connected between the end of the movable block 307 away from the rotating disk 304 and the inner wall of the fixed frame 305. Through the arrangement of the fixed frame 305, the spring 308 and the movable block 307, the rotating disk 304 is locked. When the movable block 307 cooperates with the slot on the outer surface of the rotating disk 304, the rotating block 302 can seal the cylindrical cavity inside the hopper 301 to prevent external debris from entering the heating component 2 through the feed channel 309.

[0035] Specifically, a rod 306 is inserted inside the fixed frame 305, and two holes are opened inside the movable block 307 to cooperate with the rod 306. When the rod 306 cooperates with the hole inside the movable block 307 on the side near the rotating disk 304, the movable block 307 is completely separated from the slot on the outer surface of the rotating disk 304, thereby unlocking the rotating disk 304. When the rod 306 cooperates with the hole inside the movable block 307 on the side near the rotating disk 304, the movable block 307 can cooperate with the slot on the outer surface of the rotating disk 304, thereby locking the rotating disk 304.

[0036] Furthermore, pull out the pins on both sides and slide the moving block 307 to separate the moving block 307 from the slot on the outer surface of the rotating disk 304, thereby unlocking the rotating disk 304. At this time, reinsert the pins into the fixing frame 305 to fix the moving block 307 and prevent it from being reinserted into the slot. Then, the rotation of the rotating disk 304 drives the rotating shaft 303 to rotate, which in turn drives the rotating block 302 to rotate, causing the coffee beans inside the hopper 301 to fall into the cylindrical cavity. Through the rotation of the rotating block 302 with a semi-circular cross-section, the coffee beans are driven to enter the heating component 2 from the feed channels 309 on both sides for heating. This allows for multiple additions of coffee beans, avoiding the accumulation of too many coffee beans at once, which would affect the roasting of the coffee beans. The connection relationship, working principle, and operation sequence between the heating component 2 and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated further here.

[0037] Example 2

[0038] Reference Figure 1 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The cooling component 4 includes a storage tray 403 disposed on the upper surface of the casing 1. A movable cylinder 402 is inserted inside the storage tray 403. A drive shaft 405 is inserted inside the movable cylinder 402. A scraper 404 is movably connected inside the drive shaft 405 through a movable pin.

[0039] Specifically, a geared motor 406 is fixedly installed inside the casing 1. The output end of the geared motor 406 is fixedly connected to the bottom end of the transmission shaft 405. A rectangular groove is provided inside the transmission shaft 405. The inner wall of the rectangular groove is provided with a sliding groove that cooperates with the movable pin. Through the setting of the rectangular groove and the sliding groove, the scraper 404 can rotate by cooperating with the movable pin, and the scraper 404 can drive the movable pin to slide in the sliding groove, thereby realizing the scraper 404 being retracted into the rectangular groove.

[0040] Specifically, the upper surface of the casing 1 is provided with a groove that mates with the storage tray 403. The storage tray 403 is located inside the groove. The inside of the storage tray 403 is provided with a circular hole that mates with the movable cylinder 402. The inner wall of the circular hole is provided with an internal thread groove. The bottom outer surface of the movable cylinder 402 is provided with an external thread. Through the thread on the bottom outer surface of the movable cylinder 402, when the storage tray 403 needs to be lifted, the movable cylinder 402 is pulled upward. When the thread at the bottom of the movable cylinder 402 mates with the internal thread groove of the circular hole inside the storage tray 403, the movable cylinder 402 is rotated, thereby lifting and fixing the movable cylinder 402 inside the storage tray 403, thus preventing coffee beans from falling out of the circular hole inside the storage tray 403.

[0041] Specifically, a baffle block 407 is fixedly installed on the top of the movable cylinder 402, a fixed plate 408 is fixedly installed on the bottom of the movable cylinder 402, and an insert 401 is inserted into the top of the drive shaft 405. The bottom of the insert 401 is provided with a slot that cooperates with the scraper 404. The baffle block 407 and the fixed plate 408 prevent the movable cylinder 402 from separating from the storage tray 403. The insert 401 prevents coffee beans from falling into the rectangular groove inside the drive shaft 405.

[0042] Furthermore, after the roasted coffee beans are output from one side of the heating element 2, they fall into the storage tray 403. The geared motor 406 drives the drive shaft 405 to rotate, which scrapes the coffee beans in the storage tray 403 to help dissipate heat and prevent the coffee beans from piling up and affecting heat dissipation. After heat dissipation is complete, the insert 401 is removed, thereby exposing the rectangular groove inside the drive shaft 405. Then, the scraper 404 is rotated so that the scraper 404 can drive the movable pin into the rectangular groove inside the drive shaft 405, and the storage tray 403 can be removed directly, which makes it easy to take out the coffee beans, replacing the traditional fixed storage tray 403, and eliminating the need to use additional tools to remove the coffee beans.

[0043] Working principle: During coffee bean roasting, the heating element 2 is activated, then the pins on both sides are pulled out, and the sliding block 307 is slid to separate the sliding block 307 from the slot on the outer surface of the rotating disk 304, thereby unlocking the rotating disk 304. At this time, the pins are reinserted into the fixing frame 305 to fix the sliding block 307 and prevent it from re-inserting into the slot. Then, the rotation of the rotating disk 304 drives the rotating shaft 303 to rotate, which in turn drives the rotating block 302 to rotate, causing the coffee beans inside the hopper 301 to fall into the cylindrical cavity. Through the rotation of the semi-circular rotating block 302, the coffee beans are sequentially fed into the heating element 2 from the feed channels 309 on both sides for heating. This allows for multiple additions of coffee beans, avoiding the accumulation of too many coffee beans at once, which would affect the roasting process. After roasting, the coffee beans are output from one side of the heating element 2 and fall into the storage container. Inside the storage tray 403, the geared motor 406 drives the drive shaft 405 to rotate, which scrapes the coffee beans falling into the storage tray 403 to level them, thus aiding in heat dissipation and preventing the coffee beans from piling up and affecting heat dissipation. After heat dissipation is complete, the insert 401 is removed, exposing the rectangular groove inside the drive shaft 405. Then, the scraper 404 is rotated so that the scraper 404 can drive the movable pin into the rectangular groove inside the drive shaft 405. Then, the movable cylinder 402 is pulled upward. When the thread at the bottom of the movable cylinder 402 engages with the internal thread groove of the round hole inside the storage tray 403, the movable cylinder 402 is rotated to lift and fix the movable cylinder 402 inside the storage tray 403, thus preventing the coffee beans from falling out of the round hole inside the storage tray 403. At this point, the storage tray 403 can be directly removed, making it easy to take out the coffee beans. This replaces the traditional fixed storage tray 403, eliminating the need for additional tools to remove the coffee beans, making it convenient to use and ultimately completing the coffee bean roasting process.
