Description

Technical Field

[0001] The present application relates to the technical field of coffee drying, and in particular to a device and process for drying fine coffee. Background Art

[0002] Coffee drying is an important step in the coffee production process. It involves reducing the moisture content in the coffee beans to a level suitable for storage and transportation. The quality of coffee drying also directly affects the flavor and quality of the coffee beans, so this process needs to be controlled very carefully.

[0003] For example, a coffee bean hot air drying device and drying method with publication number CN116058512A relates to the technical field of coffee bean processing. The coffee bean hot air drying device includes a drying box, a loading assembly, a flipping and unloading assembly and a hot air assembly. Air-permeable drying plates are fixedly installed on the inner walls of both sides of the drying box. The loading assembly is arranged on the drying box, and the loading assembly is used to protect the air-permeable drying plate. The flipping and unloading assembly is arranged on the drying box. The flipping and unloading assembly includes a reduction motor and a scraper plate. The reduction motor can drive the scraper plate located inside the drying box to rotate, and the scraper plate is used to unload the coffee beans on the air-permeable drying plate. The coffee bean hot air drying device and drying method can increase the uniformity of the coffee beans during drying, and can reduce the time and labor intensity of workers taking out the coffee beans during the drying process. At the same time, scraping by the scraper plate can increase the unloading speed of the coffee beans, thereby improving the overall drying efficiency of the coffee beans.

[0004] However, the above-mentioned prior art still has some defects in coffee drying: 1. When the above-mentioned patent application uses hot air to dry the coffee beans, since the fan blades are arranged in a straight line and the electric heating wire is located above the fan blades, when the hot air reaches the breathable drying plate, only the hot air temperature of the breathable drying plate area corresponding to the electric heating wire is the highest, and the temperature of the hot air becomes lower and lower as it diffuses from this area to the surrounding directions, resulting in uneven heating of the coffee beans on the breathable drying plate, thereby damaging the flavor and quality of the coffee beans.

[0005] 2. The length of the strip opening for discharging materials on the breathable drying plate in the above patent application is shorter than the radius of the breathable drying plate, and the scraper plate is also shorter than the radius of the breathable drying plate, which results in some coffee beans being missed when the scraper plate is scraping, resulting in a reduction in the yield of coffee beans. At the same time, if not cleaned in time, these coffee beans will be reheated, resulting in overheating of the coffee beans, thereby damaging their flavor and quality.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for coffee drying methods. Summary of the invention

DETAILED DESCRIPTION

[0049] The following is combined with Figures 1 to 13 This application is described in further detail.

[0050] The embodiment of the present application discloses a boutique coffee drying device, which stirs and turns the coffee beans on a drying plate 3 during the hot air drying process so that the coffee beans are heated evenly, thereby improving the flavor and quality of the coffee beans.

[0051] Embodiment 1:

[0052] Reference Figure 1 , Figure 2 and Figure 3A fine coffee drying device comprises a shell 1, a rotating rod 2 is provided at the center of the shell 1 along the height direction, and a plurality of drying plates 3 are provided along the axial direction of the rotating rod 2.

[0053] A rotating ring 4 is provided at the top of the drying plate 3 along its axial direction, and a plurality of stirring support rods 5 and flip support rods 6 are respectively provided on the rotating ring 4 from the center to the surrounding directions thereof. A plurality of stirring rods 51 are installed on the stirring support rod 5 on the side close to the drying plate 3, and a stirring plate 52 is provided on the end of the stirring rod 51 close to the drying plate 3 to stir the coffee beans on the drying plate 3 so that they are evenly heated. The stirring plate 52 is slidably connected to the drying plate 3, and a plurality of flip plates 61 are installed on the side of the flip support rod 6 close to the drying plate 3 to flip the coffee beans on the drying plate 3 so that all sides are evenly heated, and the flip plate 61 is slidably connected to the drying plate 3.

[0054] The housing 1 is provided with a plurality of air outlets 11 on both inner walls along the length direction thereof.

[0055] Reference Figure 8 A ventilation cavity 31 is provided inside the drying plate 3 , and a water guide ring 32 is installed between the ventilation cavity 31 and the rotating rod 2 .

[0056] When the equipment is running, hot air is continuously input into the shell 1 through the air outlets 11 on the inner walls on both sides of the shell 1, and the coffee beans on the drying plate 3 are heated and dried. In the specific implementation process, under external drive (not shown in the figure), the rotating rod 2 drives the drying plate 3 and the rotating ring 4 to start rotating, and the rotating ring 4 simultaneously drives the stirring support rod 5 and the flip support rod 6 to rotate. The stirring support rod 5 and the drying plate 3 cooperate with each other to drive the stirring plate 52 to rotate, and then the stirring plate 52 can stir the coffee beans on the drying plate 3 to avoid uneven heating of the coffee beans, thereby affecting the quality and flavor of the coffee beans; during the rotation of the flip support rod 6, the flip plate 61 will flip the coffee beans on the drying plate 3 to ensure that all sides of the coffee beans can be heated, thereby making them heated evenly and improving the drying efficiency of the coffee beans.

[0057] Among them, the top plate surface of the drying plate 3 is made of a material with good thermal conductivity. During the specific implementation process, when hot air passes through the ventilation cavity 31, the heat of the hot air can be transferred to the coffee beans through the plate surface, and then the coffee beans can be heated and dried, and the coffee beans can be heated evenly, further improving the drying efficiency of the coffee beans.

[0058] The moisture attached to the coffee beans when they are just placed on the drying tray 3, as well as the moisture partially evaporated and condensed during the drying process of the coffee beans, can be collected into the water guide ring 32 through the drying tray 3 and finally collected by the collecting device, thereby reusing water resources.

[0059] Reference Figure 3and Figure 4 In order to enable the stirring plate 52 to rotate and thus stir the coffee beans on the drying plate 3, a rotating shaft 53 is rotatably installed at the center of the stirring support rod 5 through a bearing, and a plurality of first driving bevel gears 531 are arranged on the outer wall of the rotating shaft 53 along the axial direction thereof. A linkage bevel gear 54 is arranged at one end of the stirring rod 51 close to the corresponding first driving bevel gear 531. The first driving bevel gear 531 is meshedly connected with the linkage bevel gear 54, and the stirring support rod 5 is through-connected with the rotating ring 4.

[0060] Among them, when the hot air enters the rotating ring 4, it will drive the rotating shaft 53 to rotate. At the same time, when the rotating shaft 53 rotates in a circle around the axis of the drying plate 3 driven by the rotating ring 4 and the stirring support rod 5, the rotating shaft 53 and the circumferential edge of the drying plate 3 cooperate with each other so that the rotating shaft 53 can also rotate. In the specific implementation process, when the rotating shaft 53 rotates, it drives the first driving bevel gear 531 to rotate synchronously. The first driving bevel gear 531 drives the linkage bevel gear 54 to rotate through gear meshing transmission, so that the linkage bevel gear 54 can drive the stirring rod 51 and the stirring plate 52 to rotate, and then the stirring plate 52 can stir the coffee beans on the drying plate 3, so that the coffee beans can be evenly dried by the hot air, avoiding the damage to the flavor and quality of the coffee beans when the coffee beans are heated unevenly, and at the same time, the coffee bean drying efficiency can be improved.

[0061] Reference Figure 5 and Figure 6 An exhaust port 62 is provided between each flip plate 61 on the side of the flip support rod 6 close to the drying plate 3 , and the flip support rod 6 is connected with the rotating ring 4 through.

[0062] Among them, the diameter of the exhaust port 62 is smaller than the diameter of the coffee beans, ensuring that the coffee beans will not enter or block the exhaust port 62. During the specific implementation process, the hot air can enter the flip support rod 6 through the rotating ring 4 and be discharged through the exhaust port 62. When the flip plate 61 rotates on the drying plate 3, the flip plate 61 can flip the coffee beans on the drying plate 3, so that all sides of the coffee beans can be evenly heated, thereby improving the flavor and quality of the coffee beans, while further improving the drying efficiency of the coffee beans and saving the cost of the device.

[0063] Reference Figure 2 and Figure 7 In order to allow hot air to enter the rotating ring 4, thereby driving the rotating shaft 53 to rotate and being discharged from the exhaust port 62 to heat and dry the coffee beans, an air guide ring 41 is rotatably installed on the top of the rotating ring 4 through a bearing to guide the hot air into the rotating ring 4, and the bottom of the air guide ring 41 is opened, and a plurality of semicircular wind holes 42 are opened on the top of the rotating ring 4 to be connected with the air guide ring 41.

[0064] One end of each rotating shaft 53 inside the rotating ring 4 is equipped with a plurality of rotating blades 55 corresponding to the semicircular wind tunnel 42 to drive the rotating shaft 53 to rotate. One end of the rotating shaft 53 away from the rotating blades 55 is provided with a second driving bevel gear 532 .

[0065] A plurality of ventilation pipes 43 are installed between the air guide ring 41 and the inner walls of the shell 1 on both sides along the length direction thereof, so that hot air can be introduced into the air guide ring 41 . The ventilation pipes 43 are connected to the air guide ring 41 and the inner walls of the shell 1 on both sides.

[0066] Among them, since the air guide ring 41 and the rotating ring 4 are rotatably installed through the bearing, when the rotating ring 4 rotates, the air guide ring 41 and the ventilation pipe 43 can remain stationary, and the bearing installation positions of the two are sealed. In the specific implementation process, the hot air enters the air guide ring 41 from the ventilation pipe 43, and then the hot air enters the rotating ring 4 through the semicircular wind tunnel 42 in the air guide ring 41, and blows the rotating blades 55 to rotate. The semicircular wind tunnel 42 faces the rotating blades 55 on one side of the rotating shaft 53. After the hot air enters the rotating ring 4 through the semicircular wind tunnel 42, it can ensure that the rotating blades 55 are directly blown to rotate, and the rotating blades 55 on both sides of the rotating shaft 53 are prevented from being blown by the hot air at the same time, thereby maintaining a balanced state so that the rotating shaft 53 cannot rotate. At the same time, when the second driving bevel gear 532 rotates on the drying plate 3 with the rotating shaft 53, the second driving bevel gear 532 can cooperate with the circumferential edge of the drying plate 3 to also rotate the rotating shaft 53, and then when the wind force of the hot air is reduced, it can still be ensured that the rotating shaft 53 can rotate.

[0067] When the rotating shaft 53 rotates, the stirring plate 52 is driven to rotate through the meshing transmission of the first driving bevel gear 531 and the linkage bevel gear 54, so that the stirring plate 52 can stir the coffee beans, thereby making the coffee beans evenly heated during hot air drying, thereby avoiding the degradation of the coffee beans quality due to uneven heating.

[0068] The hot air in the rotating ring 4 can also enter the flip support rod 6 and be discharged through the exhaust port 62. Then, when the flip plate 61 flips the coffee beans, the hot air can heat and dry the coffee beans on the flip plate 61, thereby improving the drying efficiency of the coffee beans and saving the cost of the device.

[0069] Reference Figure 8 In order to collect the moisture attached to the coffee beans and the moisture partially evaporated and condensed during the drying process of the coffee beans, the surface of the drying plate 3 is provided with a water guide ring 33, the water guide ring 33 is connected to the water guide annular channel 32, and the slope of the surface of the drying plate 3 gradually increases from the water guide ring 33 to both sides thereof.

[0070] Among them, the diameter of the water guide ring 33 is smaller than the diameter of the coffee beans, ensuring that the coffee beans will not enter or block the water guide ring 33. During the specific implementation process, the moisture attached to the coffee beans and the moisture partially evaporated and condensed during the drying process of the coffee beans flow into the water guide ring 33 through the slope of the drying plate 3, and flow into the water guide channel 32 through the water guide ring 33. The water in the water guide channel 32 is finally collected by the device for reuse, thereby saving water resources.

[0071] Reference Figure 8 In order to collect and utilize the water in the water guide channel 32, a water passage cavity 21 is provided inside the rotating rod 2. The water passage cavity 21 is connected to the water guide channel 32 through-connection, and a moisture collecting plate 22 is connected to the bottom of the water passage cavity 21 to collect the moisture generated during the drying process of the coffee beans.

[0072] Among them, the connection between the water cavity 21 and the water guiding channel 32 is located at the bottom of the water guiding channel 32 to ensure that all water flows can enter the water cavity 21 through the water guiding channel 32. During the specific implementation process, the water collected in the water guiding channel 32 flows into the water cavity 21, and finally enters the water collection plate 22 through the water cavity 21 for recovery, thereby realizing the recovery and utilization of water and avoiding the waste of water resources.

[0073] Reference Figure 8 and Fig.13 In order to allow the coffee beans on the drying plate 3 to be heated more evenly, an elliptical ventilation duct 34 is connected through the ventilation cavity 31, and the elliptical ventilation duct 34 and the rotating ring 4 are also connected through.

[0074] A plurality of air outlets 35 are provided on one side of the drying plate 3 near the rotating ring 4 . The air outlets 35 are connected to the ventilation cavity 31 . A circle of gear bars 36 are provided on the top of the air outlets 35 along the edge of the drying plate 3 . The gear bars 36 are meshed with the second driving bevel gear 532 .

[0075] Among them, the diameter of the air supply port 35 is smaller than the diameter of the coffee beans, ensuring that the coffee beans will not enter or block the air supply port 35. In the specific implementation process, the hot air enters the elliptical ventilation duct 34 through the rotating ring 4, and then enters the ventilation cavity 31 from the elliptical ventilation duct 34. Because the top disk surface of the drying plate 3 is made of a material with good thermal conductivity, when the hot air passes through the ventilation cavity 31, the hot air will transfer the heat to the coffee beans through the disk surface of the drying plate 3, thereby making the coffee beans more evenly heated, so that the coffee beans can be better dried.

[0076] The hot air passes through the ventilation cavity 31 and is finally discharged from the air supply port 35. Then, with the cooperation of the hot air output from the air supply port 35, the exhaust port 62 and the air outlet 11 and the stirring plate 52, the coffee beans can be heated and dried multiple times and evenly, thereby avoiding uneven heating of the coffee beans that may damage their quality and flavor, while saving the cost of the device.

[0077] When the stirring support rod 5 rotates on the drying plate 3, the second driving bevel gear 532 inside the stirring support rod 5 is meshed with the gear bar 36 for transmission, thereby driving the rotating shaft 53 to rotate. The rotating shaft 53 simultaneously drives the first driving bevel gear 531 to rotate. With the cooperation of the first driving bevel gear 531 and the linkage bevel gear 54, the stirring plate 52 rotates, thereby stirring the coffee beans on the drying plate 3, so that they are evenly heated.

[0078] Reference Fig. 9 and Fig.12 In order to discharge the dried coffee beans out of the drying device, the drying plate 3 is provided with a discharge channel 37, and a discharge plate 38 is provided on the top of the discharge channel 37. The end of the discharge plate 38 close to the rotating ring 4 is hinged to the drying plate 3, and a discharge box 39 is provided below the discharge channel 37. The side of the discharge box 39 away from the drying plate 3 is connected with a discharge pipe 7 to discharge the dried coffee beans.

[0079] A discharge blocking plate 71 is provided above the point where the discharge pipe 7 and each discharge box 39 are connected.

[0080] The discharge plate 38 is slidably connected to the discharge channel 37, the discharge channel 37 passes through the drying plate 3, and the discharge box 39 gradually increases in slope from its end close to the discharge pipe 7 to its end away from the discharge pipe 7. In the specific implementation process, after the coffee bean drying process is completed, the end of the discharge plate 38 away from the rotating ring 4 starts to rotate around the end close to the rotating ring 4, and the coffee beans on the drying plate 3 fall into the discharge box 3 along the discharge plate 38 under the guidance of the slope of the drying plate 3 and the drive of the stirring plate 52. The coffee beans are placed in the material box 39 and enter the discharge pipe 7 through the discharge box 39. When the coffee beans enter the discharge pipe 7, a discharge baffle plate 71 is provided above the connection between the inside of the discharge pipe 7 and each discharge box 39. Therefore, the coffee beans falling from the upper part of the discharge pipe 7 will not enter the discharge box 39 below due to the obstruction of the discharge baffle plate 71. The slope setting of the discharge box 39 can also prevent the coffee beans falling from the upper part from falling into the discharge box 39 below, thereby avoiding incomplete collection of coffee beans and resulting in waste of coffee beans.

[0081] Continue to refer to Fig. 9 An air storage box 310 is installed on the side wall of the discharge channel 37 away from the discharge pipe 7, and a discharge telescopic rod 311 is installed between the bottom of the discharge plate 38 and the air storage box 310 to control the opening and closing of the discharge plate 38.

[0082] An air supply pipe 312 is installed on the inner wall of the air storage box 310 and the shell 1 near the air storage box 310 . The air supply pipe 312 is connected to the air storage box 310 and the inner wall of the shell 1 , and an air pump 313 is sleeved on the air supply pipe 312 .

[0083] During the specific implementation process, when the coffee beans are dried, hot air enters the gas storage box 310 through the air duct 312, and the discharging telescopic rod 311 is extended through the gas storage box 310 to support the discharging plate 38, thereby ensuring that the coffee beans will not enter the discharging channel 37 during the drying process. At the same time, the air pump 313 can also transport gas into the air duct 312, and the gas passes through the gas storage box 310 to extend the discharging telescopic rod 311 to support the discharging plate 38. When the hot air and the air pump 313 both transport gas into the gas storage box 310 to support the discharging plate 38, it can be ensured that the discharging telescopic rod 311 can be extended and retracted to support the discharging plate 38.

[0084] Embodiment 2:

[0085] Reference Fig.11 A feed pipe 8 is provided at the shell 1 near the drying plate 3 along its height direction. A discharge pipe 81 is provided above each drying plate 3. The discharge pipe 81 is connected with the feed pipe 8. A feed baffle plate 82 is provided inside the feed pipe 8 and above the connection point of each discharge pipe 81; the top of the feed pipe 8 passes through the shell 1 and is provided with a feed port 83. A semicircular funnel 84 is provided at the half of the feed port 83 close to the drying plate 3, and a feed telescopic rod 85 is provided at the half of the feed port 83 away from the drying plate 3. A guide plate 86 is installed at the bottom of the feed telescopic rod 85.

[0086] During the specific implementation process, coffee beans are poured into the semicircular funnel 84, and the coffee beans enter from the feed pipe 8. Under external drive (not shown in the figure), the feed telescopic rod 85 is controlled to extend and retract to drive the guide plate 86 to the discharge pipe 81 of the first drying plate 3 close to the semicircular funnel 84. Under the guidance of the guide plate 86, the coffee beans enter the drying plate 3 from the discharge pipe 81. Then, the feed telescopic rod 85 is controlled again to drive the guide plate 86 to the discharge pipe 81 of the second drying plate 3 close to the semicircular funnel 84. At this time, the first feed blocking plate 82 close to the semicircular funnel 84 will block the discharge pipe 81, so that the fallen coffee beans will not enter the discharge pipe 81, thereby preventing the coffee beans from being discharged evenly and then being heated evenly. The above process is repeated for subsequent discharge.

[0087] Reference Fig.10 A water vapor collecting plate 12 is provided at the top of the inner wall of the shell 1 , and a collecting pipe 13 is provided on the water vapor collecting plate 12 , and the collecting pipe 13 runs through the top of the shell 1 .

[0088] During specific operation, under external drive (not shown in the figure), the water vapor generated by evaporation of coffee beans during hot air drying is absorbed by the water vapor collecting plate 12, and the water vapor is input into the collecting device (not shown in the figure) through the collecting pipe 13 for collection.

[0089] Finally, the present invention also provides a specialty coffee drying process, and the method of using the process comprises the following steps:

[0090] S1: Uniform feeding: Pour coffee beans into the semicircular funnel 84, and under external drive, the feeding telescopic rod 85, the guide plate 86 and the feeding pipe 8 cooperate to achieve uniform placement of coffee beans in each drying plate 3;

[0091] S2: stirring and flipping: the coffee beans in the drying plate 3 are stirred and flipped by the stirring plate 52 and the flipping plate 61 to be evenly heated;

[0092] S4: Hot air heating: The air outlet 11 of the housing 1 and the air outlet 62 and air supply outlet 35 on the drying plate 3 all send out hot air to heat the coffee beans;

[0093] S5: Water collection: The water guide ring 32 and the water passage cavity 21 collect water attached to the coffee beans, and a water vapor collection plate 12 is provided on the top of the housing 1 to collect water vapor evaporated from the coffee beans;

[0094] S6: Automatic discharging: After the hot air drying is completed, the discharging plate 38 is opened, and the coffee beans are discharged from the housing 1 under the cooperation of the discharging box 39 and the discharging pipe 7.
