Description

Technical Field

[0001] This utility model relates to the field of coffee processing equipment technology, and in particular to a coffee bean drying device. Background Technology

[0002] After fresh coffee cherries are picked from the coffee tree, they first need to go through multiple processing steps, including peeling, degumming, drying, storage, shelling, and polishing. After roasting, they become the coffee beans that we can buy in the market.

[0003] The existing Chinese patent with publication number CN210538803U discloses a coffee bean drying device. The existing technical solution mentioned above has the following defects. Although the above technical solution can effectively improve drying efficiency, reduce dependence on weather, and effectively shorten drying time by using a motor to drive the drying disc to rotate and using a rake to stir and turn the coffee beans on the drying disc, the above technical solution can only stir the coffee beans and cannot easily mix the coffee beans at the bottom. This can easily cause uneven drying and reduce the drying effect. Utility Model Content

[0027] Please refer to Figure 1-4A coffee bean drying device includes a drying chamber 1, a support box 12 on the outer side of the drying chamber 1, and connecting grooves 13 on both sides of the inner wall of the support box 12. Connecting blocks 14 are provided on both sides of the drying chamber 1, with one end of each connecting block 14 extending into the interior of the connecting groove 13. A mounting shell 18 is located at the middle of the upper bottom surface of the support box 12, and a motor 16 is mounted on the lower top surface of the mounting shell 18. A second gear 17 is fixedly connected to the output end of the motor 16. A shaft seat is located at the middle of both sides of the inner wall of the support box 12, and a connecting rod 21 is provided in the shaft seat. A first gear 15 is provided at one end of the connecting rod 21. The first gear 15 meshes with the second gear 17. Guide wheels 20 are provided on both sides of the bottom surface of the drying chamber 1. A cam 22 is provided on the connecting rod 21 below the guide wheels 20. Fans 19 are installed on both sides of the upper bottom surface of the drying chamber 1. Heaters 25 are installed on both sides of the inner wall of the drying chamber 1. A partition 11 is provided inside the drying chamber 1 above the heaters 25, and a through hole 10 is provided on the top surface of the partition 11. A rotating rod 6 is provided on the top surface of the second gear 17, penetrating the drying chamber 1 and the partition 11. A fixing rod 9 is provided on the rotating rod 6 above the partition 11, and an auxiliary stirring blade 8 is provided at one end of the fixing rod 9. The rotating rod 6 has first stirring blades 7 on both sides of the fixed rod 9. A feed inlet 4 is located in the middle of the top surface of the drying chamber 1, and a baffle 5 runs through one side of the feed inlet 4. Opening the baffle 5 allows the coffee beans to be dried to be placed into the drying chamber 1. Turning on the fans 19 on both sides of the bottom upper surface of the drying chamber 1, and using the heater 25, the coffee beans in the drying chamber 1 can be dried. The motor 16 is turned on, driving the second gear 17 to rotate, causing the rotating rod 6 on the second gear 17 to rotate. The first stirring blades 7 on the rotating rod 6 and the auxiliary stirring blades at one end of the fixed rod 9 further contribute to the drying process. The use of the stirring blade 8 can stir and mix the coffee beans in the drying chamber 1. The second gear 17 rotates while driving the first gear 15 on the connecting rod 21 to rotate, which in turn drives the cam 22 on the connecting rod 21 to rotate. As the cam 22 rotates, it drives the guide wheels 20 on both sides of the bottom surface of the drying chamber 1 to move, so that the drying chamber 1 can move up and down. With the use of the stirring component on the rotating rod 6, the coffee beans in the drying chamber 1 can be stirred up and down, which increases the fluidity of the coffee beans in the drying chamber 1, makes them heat more evenly, and thus improves the drying efficiency of the coffee beans.

[0028] In one embodiment, the top surface of the drying chamber 1 is provided with through grooves 2 on both sides of the feed inlet 4, and a filter screen 3 is provided in the through grooves 2. The use of the through grooves 2 allows the air in the drying chamber 1 to circulate, thereby drying the coffee beans in the drying chamber 1.

[0029] In one embodiment, the front surface of the drying chamber 1 is hinged with a discharge door 23, which allows the dried coffee beans to be removed by opening the discharge door 23.

[0030] In one embodiment, the connecting block 14 and the connecting groove 13 are movably connected. The use of the connecting block 14 on both sides of the drying box 1 and the connecting groove 13 on both sides of the inner wall of the support box 12 can limit the position of the drying box 1, thereby facilitating the maintenance of the stability of the drying box 1 during movement.

[0031] In one embodiment, a handle is provided at the middle position of one side surface of the baffle 5, outside the feed inlet 4. The baffle 5 is movably connected to the feed inlet 4, and the baffle 5 can be easily pulled out of the feed inlet 4 by using the handle.

[0032] In one embodiment, the front surface of the support box 12 is provided with a movable plate 24, and the movable plate 24 is fixedly connected to the support box 12 by screws. By loosening the screws and removing the movable plate 24, the components in the support box 12 can be maintained and repaired.

[0033] In one embodiment, a plurality of through holes 10 are provided, and the plurality of through holes 10 are evenly distributed on the top surface of the partition 11. The use of the through holes 10 on the top surface of the partition 11 allows hot air to enter above the partition 11, so that the hot air can come into contact with the coffee beans in the drying chamber 1. With the use of the stirring component, the coffee beans can be fully heated, thereby improving the drying effect of the coffee beans.

[0034] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] In use, open the baffle 5, place the coffee beans to be dried into the drying chamber 1, turn on the fans 19 on both sides of the bottom upper surface of the drying chamber 1, and then use the heater 25 to dry the coffee beans in the drying chamber 1. The motor 16 is turned on, driving the second gear 17 to rotate, causing the rotating rod 6 on the second gear 17 to rotate. The first stirring blade 7 on the rotating rod 6 and the auxiliary stirring blade 8 at one end of the fixed rod 9 stir and mix the coffee beans in the drying chamber 1. Simultaneously, the rotation of the second gear 17 drives the first gear 15 on the connecting rod 21 to rotate, causing the cam 22 on the connecting rod 21 to rotate. The rotation of the cam 22, in turn, moves the guide wheels 20 on both sides of the bottom surface of the drying chamber 1, causing the coffee beans to dry. The drying chamber 1 can move up and down. With the use of the stirring component on the rotating rod 6, the coffee beans in the drying chamber 1 can be stirred up and down, increasing the fluidity of the coffee beans in the drying chamber 1 and making them heat more evenly, thereby improving the drying efficiency of the coffee beans. The use of connecting blocks 14 on both sides of the drying chamber 1 and connecting grooves 13 on both sides of the inner wall of the support box 12 can limit the position of the drying chamber 1, thereby facilitating the stability of the drying chamber 1 during movement. The use of through holes 10 on the top surface of the partition 11 allows hot air to enter above the partition 11, so that the hot air can come into contact with the coffee beans in the drying chamber 1. With the use of the stirring component, the coffee beans can be fully heated, thereby improving the drying effect of the coffee beans.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
