Description
Technical Field
[0001] This invention relates to the technical field of coffee cherry peeling and degumming equipment, specifically to an integrated machine for peeling and degumming fresh coffee cherries. Background Technology
[0002] Coffee, as a vital beverage worldwide, holds a significant place in people's daily lives. Currently, coffee cultivation and distribution are mainly concentrated in tropical and subtropical regions. Its unique flavor and remarkable health benefits have made it a favorite among consumers, especially the recently popular Yunnan "small-bean coffee," which has seen supply shortages. The initial processing of fresh coffee cherries directly affects the overall flavor of the coffee, thus placing higher demands on processing equipment.
[0003] Existing coffee peeling and degumming machines mainly combine peeling and degumming equipment, which suffers from problems such as inability to separate unripe coffee cherries, high equipment connection issues and breakage rates, and large footprint. Therefore, it is necessary to improve existing peeling and degumming equipment to address equipment connection issues, separate unripe coffee cherries, and reduce breakage rates, thereby increasing the utilization rate of fresh coffee cherries. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an integrated machine for peeling and degumming fresh coffee cherries. It has the advantages of separating green cherries from fresh coffee cherries, improving the connection between peeling and degumming, and reducing the breakage rate of fresh coffee cherries. It solves the problems of current coffee cherry peeling and degumming equipment being unable to separate green cherries, resulting in low quality of processed products, and poor connection between equipment, leading to a high breakage rate of fresh cherries during peeling and degumming.
[0005] Technical solution
[0006] To achieve the above-mentioned goals of separating green coffee cherries, improving the peeling and degumming process, and reducing the breakage rate of fresh coffee cherries, this invention provides the following technical solution: an integrated peeling and degumming machine for fresh coffee cherries, including a feeding hopper mechanism. The bottom end of the feeding hopper mechanism is connected to a support frame via bolts. A peeling mechanism is fixedly connected to the support frame. A conveying pipe is fixedly connected to the bottom end of the peeling mechanism. A conveying screw is rotatably installed inside the conveying pipe. One end of the conveying pipe is connected to a sorting mechanism via bolts. A secondary peeling and pre-degumming mechanism is provided below the sorting mechanism. A degumming mechanism is bolted to one side of the secondary peeling and pre-degumming mechanism.
[0007] The feeding hopper mechanism includes a feeding barrel, a limiting device, and a guiding device. The feeding barrel is located at the top of the entire feeding hopper mechanism, and the limiting device is welded to the bottom of the feeding barrel. The guiding device is fixedly installed at the top of the peeling mechanism.
[0008] The peeling mechanism includes a first peeling cutter, a peeling discharge hopper, a peeling rotating shaft, a transmission gear, and a transmission shaft. The first peeling cutter is installed around the cone-shaped barrel at the top of the peeling mechanism. The transmission gear is rotatably connected inside the peeling discharge hopper. The transmission gear meshes with the bevel gear of the peeling rotating shaft. The center of the transmission gear is fixedly connected to the transmission shaft.
[0009] The sorting mechanism includes a sorting screen, a green fruit outlet chute, and a cover plate counterweight. One end of the sorting screen is connected to the green fruit outlet chute by bolts, and a cover plate counterweight is hinged to the outlet of the green fruit outlet chute.
[0010] The degumming mechanism includes a central shaft rotating assembly, a degumming discharge hopper, a degumming screen, a motor adjusting device, and a degumming machine frame. The central shaft rotating assembly is located inside the degumming screen, the motor adjusting device is mounted on a support frame, and the degumming machine frame supports the entire degumming mechanism.
[0011] Preferably, the material limiting device includes a circular shell with a groove on its outer surface. A limiting plate is inserted into the groove, and a handle is fixedly connected to the outer surface of the limiting plate. The top end of the drive shaft extends into the interior of the material guiding device, and a material guiding cylinder is provided below the material guiding device. A material guiding chute is provided inside the material guiding cylinder.
[0012] Through the above technical solution, fresh coffee cherries are temporarily stored in the feeding hopper. In the initial state, the fresh coffee cherries are blocked by the limiting plate of the limiting device and are in the feeding hopper. By adjusting the handle, the limiting plate is moved, thereby opening a gap so that the fresh coffee cherries can slide from the feeding hopper onto the guide chute and finally slide into the channel of the first peeling blade of the peeling mechanism. The size of the gap can be adjusted by adjusting the position of the limiting plate by the handle, thereby adjusting the speed at which the fresh coffee cherries fall into the cone of the peeling mechanism.
[0013] Preferably, the peeling mechanism is bolted to a first peeling cutter, and the outer surface of the peeling rotating shaft and the transmission gear is provided with a cover, which is installed inside the peeling discharge hopper.
[0014] Through the above technical solution, when the peeling rotating shaft rotates, the bevel gear at one end can drive the transmission gear to rotate, the transmission gear drives the transmission shaft to rotate, the transmission shaft drives the cone to rotate, and the cone rotates, causing the sieve outside it to rotate, which causes the coffee fruit to rub against the protrusions of the sieve, thereby achieving the initial peeling effect of the coffee fruit.
[0015] Preferably, the bottom end of the peeling discharge hopper is bolted to the conveying pipe, and the conveying screw includes a drum shaft, a screw and a guide plate. The drum shaft is disposed inside the conveying pipe and extends into the sorting screen. The screw and the guide plate are fixedly connected to the outer surface of the drum shaft.
[0016] Through the above technical solution, after the coffee cherries are peeled for the first time by the peeling mechanism, they fall into the conveying pipe set outside the conveying screw. The rotation of the central shaft of the drum can drive the spiral on its outer surface to rotate, so that the coffee cherries after the first peeling are conveyed to the sorting screen. Finally, the peeled coffee cherries fall from the sorting screen and enter the gap between the drum and the second peeling blade. The unripe cherries mixed in are too large to fall from the sorting screen and are gradually carried by the guide plate to the leftmost end of the conveying screw. Due to the setting of the cover plate counterweight, the lighter coffee beans or coffee skins cannot push the cover plate, while the heavier unripe coffee cherries can push the cover plate counterweight and be discharged from the unripe cherry outlet chute. The overall structure can separate unripe cherries and coffee beans.
[0017] Preferably, the secondary peeling and pre-degumming mechanism includes a roller, a sieve, and a second peeling blade. The sieve is provided on the outer surface of the roller, and the secondary peeling blade is fixedly installed on the outer side of the roller.
[0018] Through the above technical solution, after the coffee beans are sorted by the sorting mechanism, they enter the gap between the drum and the second peeling blade. A sieve is installed on the outer surface of the drum, and the second peeling blade is fixed. After the coffee cherries fall into the gap between the sieve and the second peeling blade, the coffee cherries are rubbed again to achieve a secondary peeling effect, which makes the peeling effect of the coffee cherries better.
[0019] Preferably, both ends of the conveying screw are fixedly connected to pulleys, one end of the peeling rotating shaft is also fixedly connected to a pulley, and the shaft end of the secondary peeling and pre-degumming mechanism is also fixedly connected to a pulley.
[0020] Based on the above technical solutions and the accompanying drawings, Figure 1 It can be seen that a motor, in conjunction with a pulley and belt, drives the conveyor screw to rotate. The right end of the conveyor screw is also connected to a pulley. After transmission, it drives the peeling rotating shaft to rotate. The same transmission mechanism is used to make the drum also rotate. The overall structure allows one motor to drive multiple components to rotate, saving costs.
[0021] Preferably, a feed pipe is provided on the outer surface of the degumming mechanism, and the feed pipe is connected to the left end of the secondary peeling and pre-degumming mechanism by bolts.
[0022] With the above technical solution, after the coffee beans have been peeled twice, they enter the feed pipe. The feed pipe is equipped with a conveying auger, which can transport the peeled coffee beans to the shell of the degumming mechanism. The central shaft rotating component can rotate under the drive of the drive motor and belt, thereby conveying the coffee beans that have entered the shell of the degumming mechanism upward.
[0023] Preferably, the outer surface of the central axis rotating assembly is welded with a number of staggered round steel bars of varying lengths, and water outlet holes are opened on the outer surface of the round steel bars. The interior of the central axis rotating assembly is hollow.
[0024] Through the above technical solution, the top of the central shaft rotating assembly can be connected to a water source. After the water enters the central shaft rotating assembly, it is discharged from the water outlet of the round steel. This can rinse the coffee beans, and multiple round steels can rub the coffee beans. During the rinsing and rubbing process, the gum on the outer surface of the coffee beans can be removed, making the coffee beans less sticky. Finally, the coffee beans are discharged from the degumming hopper.
[0025] Preferably, the support frame is provided with a waste conveying channel, and the outer surface of the waste conveying channel is provided with a waste outlet.
[0026] Through the above technical solution, the sieve can remove the peeled coffee skin, allowing impurities such as coffee skin to fall into the waste conveying channel, and then the peel and other materials are discharged from the waste outlet through the waste conveying channel.
[0027] Compared with the prior art, the present invention provides an integrated machine for peeling and degumming fresh coffee cherries, which has the following beneficial effects:
[0028] This invention provides an integrated machine for peeling and degumming fresh coffee cherries. By setting up a peeling mechanism, a secondary peeling mechanism, and a pre-degumming mechanism, it can completely peel the fresh coffee cherries to form coffee beans. After the first peeling, the green cherries are separated by a sorting mechanism and discharged from the green cherry outlet chute, resulting in better coffee bean quality. Furthermore, the degumming mechanism removes the gum from the outer surface of the coffee beans, making them less sticky. The integrated machine has a compact overall design, occupies less space, and has a lower breakage rate during the peeling and degumming process. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] Please see Figure 1-6 A coffee fruit peeling and degumming integrated machine includes a feeding hopper mechanism 1. The bottom end of the feeding hopper mechanism 1 is connected to a support frame 7 by bolts. A peeling mechanism 2 is fixedly connected to the support frame 7. A conveying pipe is fixedly connected to the bottom end of the peeling mechanism 2. A conveying screw 3 is rotatably installed inside the conveying pipe. One end of the conveying pipe is connected to a sorting mechanism 4 by bolts. A secondary peeling and pre-degumming mechanism 5 is installed below the sorting mechanism 4. A degumming mechanism 6 is bolted to one side of the secondary peeling and pre-degumming mechanism 5.
[0039] The feeding hopper mechanism 1 includes a feeding barrel 11, a limiting device 12, and a guiding device 13. The feeding barrel 11 is located at the top of the entire feeding hopper mechanism 1, and the limiting device 12 is welded to the bottom of the feeding barrel 11. The guiding device 13 is fixedly installed at the top of the peeling mechanism.
[0040] The peeling mechanism 2 includes a first peeling cutter 21, a peeling discharge hopper 22, a peeling rotating shaft 23, a transmission gear 24, and a transmission shaft 25. The first peeling cutter 21 is installed around the cone-shaped barrel at the top of the peeling mechanism 2. The first peeling cutter 21 has a coffee fruit channel inside to facilitate the transfer and peeling of the coffee fruit during the peeling process. The bottom of the first peeling cutter 21 has a cavity for installing a movable block, preferably a rubber block. A sieve is installed outside the cone-shaped barrel, and the sieve has several protrusions. The transmission gear 24 is rotatably connected inside the peeling discharge hopper 22. The transmission gear 24 meshes with the bevel gear of the peeling rotating shaft 23. The center of the transmission gear 24 is fixedly connected to the transmission shaft 25.
[0041] The sorting mechanism 4 includes a sorting screen 41, a green fruit outlet slide 42, and a cover plate counterweight 43. One end of the sorting screen 41 is connected to the green fruit outlet slide 42 by bolts, and the cover plate counterweight 43 is hinged to the outlet of the green fruit outlet slide 42.
[0042] The degumming mechanism 6 includes a central shaft rotating assembly 61, a degumming discharge hopper 62, a degumming screen 63, a motor adjusting device 64, and a degumming machine frame 65. The central shaft rotating assembly 61 is located inside the degumming screen 63, the motor adjusting device 64 is mounted on the support frame 7, and the degumming machine frame 65 supports the entire degumming mechanism 6.
[0043] Specifically, the limiting device 12 includes a circular shell with grooves on its outer surface. A limiting plate is inserted into the grooves, and a handle is fixedly connected to the outer surface of the limiting plate. The top end of the drive shaft 25 extends into the interior of the guiding device 13. A guiding cylinder is provided below the guiding device 13, and a guiding chute is provided inside the guiding cylinder. The advantage is that when fresh coffee cherries are temporarily placed in the feeding hopper 11, they are initially blocked by the limiting plate of the limiting device 12 and are located inside the guiding cylinder of the limiting device 13. By adjusting the handle, the limiting plate is moved, creating a gap that allows the fresh coffee cherries to slide from the guiding chute inside the guiding cylinder of the limiting device 13 into the cone of the peeling mechanism 2. The size of the gap can be adjusted by adjusting the position of the limiting plate with the handle, thereby adjusting the speed at which the fresh coffee cherries fall into the cone of the peeling mechanism 2.
[0044] Specifically, the peeling mechanism 2 is bolted to a first peeling cutter 21. A cover is provided on the outer surface of the peeling rotating shaft 23 and the transmission gear 24, and the cover is installed inside the peeling discharge hopper 22. The advantage is that when the peeling rotating shaft 23 rotates, the bevel gear at one end drives the transmission gear 24 to rotate, which in turn drives the transmission shaft 25 to rotate. The transmission shaft 25 then drives the cone to rotate, which in turn drives the sieve outside the cone to rotate. This causes friction between the coffee cherries and the protrusions on the sieve, thus achieving a preliminary peeling effect.
[0045] Specifically, the bottom end of the peeling discharge hopper 22 is bolted to the conveying pipe. The conveying screw 3 includes a drum shaft 31, a screw 32 and a guide plate 33. The drum shaft 31 is located inside the conveying pipe and extends into the sorting screen 41. The screw 32 and the guide plate 33 are fixedly connected to the outer surface of the drum shaft 31. The advantage is that after the coffee cherries are peeled for the first time by the peeling mechanism 2, they fall into the conveying pipe set outside the conveying screw 3. After the central shaft 31 of the drum rotates, it can drive the screw 32 on its outer surface to rotate. In this way, the coffee cherries after the first peeling are conveyed to the sorting screen 41. Finally, the peeled coffee cherries fall from the sorting screen 41 into the gap between the drum 51 and the second peeling blade 53. The unripe cherries mixed in are too large to fall from the sorting screen 41 and are gradually driven by the guide plate 33 to the leftmost end of the conveying screw 3. Because of the cover plate counterweight 43, the lighter coffee beans or coffee skins cannot push the cover plate, while the heavier unripe coffee cherries can push the cover plate counterweight 43 and be discharged from the unripe cherry outlet chute 42. The overall structure can separate unripe cherries and coffee beans.
[0046] Specifically, the secondary peeling and pre-degumming mechanism 5 includes a roller 51, a sieve 52, and a second peeling blade 53. The sieve 52 is installed on the outer surface of the roller 51, and the surface of the sieve 52 is provided with several protrusions. The secondary peeling blade 53 is fixedly installed on the outer side of the roller 51. The advantage is that after the coffee beans are sorted by the sorting mechanism 4, they enter the gap between the roller 51 and the second peeling blade 53. With the sieve installed on the outer surface of the roller 51 and the second peeling blade fixed, the coffee beans fall into the gap between the sieve and the second peeling blade 53 of the roller 51. The coffee beans rub against the protrusions on the surface of the sieve 52 again to achieve the effect of secondary peeling, making the peeling effect of the coffee beans better.
[0047] Specifically, pulleys are fixedly connected to both ends of the conveying screw 3, and a pulley is also fixedly connected to one end of the peeling rotating shaft 23. Similarly, a pulley is fixedly connected to the shaft end of the secondary peeling and pre-degumming mechanism 5. The advantage is that, according to the attached diagram in the instruction manual... Figure 1 It can be seen that a motor, in conjunction with a pulley and belt, drives the conveying screw 3 to rotate. The right end of the conveying screw 3 is also connected to a pulley. After transmission, it drives the peeling rotating shaft 23 to rotate. The same transmission is used to make the drum 51 rotate as well. The overall structure allows one motor to drive multiple components to rotate, saving costs.
[0048] Specifically, a feed pipe 66 is provided on the outer surface of the degumming mechanism 6. The feed pipe 66 is bolted to the left end of the secondary peeling and pre-degumming mechanism 5. The advantage is that when the coffee beans after secondary peeling enter the feed pipe 66, a conveying auger is provided inside the feed pipe 66, which can transport the coffee beans after secondary peeling to the housing of the degumming mechanism 6. The central shaft rotating assembly 61 can rotate under the drive of the drive motor and belt, thereby conveying the coffee beans that have entered the housing of the degumming mechanism 6 upward.
[0049] Specifically, the outer surface of the central rotating assembly 61 is welded with several staggered round steel bars 611 of varying lengths. Water outlet holes are formed on the outer surface of each round steel bar 611, and the interior of the central rotating assembly 61 is hollow. The advantage is that a water source can be connected to the top of the central rotating assembly 61. Water enters the central rotating assembly 61 and then exits through the water outlet holes of the round steel bars 611, thus rinsing the coffee beans. Furthermore, the multiple round steel bars 611 can rub the coffee beans together, removing the sticky substance from the outer surface of the coffee beans during rinsing and rubbing, making the coffee beans less sticky. Finally, the coffee beans are discharged from the degumming hopper 62.
[0050] Specifically, the support frame 7 is equipped with a waste conveying channel 8, and the outer surface of the waste conveying channel 8 is provided with a waste outlet 81. The advantage is that the sieve 52 can pull out the peeled coffee skin, so that coffee skin and other impurities fall into the waste conveying channel 8, and then the peel and other impurities are discharged from the waste outlet 81 through the waste conveying channel 8.
[0051] In this invention, the peeling component adopts a slanted blade spiral peeling method. The material moves downward spirally under the interaction of the peeling blade in the conical barrel. It is sheared and squeezed multiple times in the first peeling blade channel to complete the separation of coffee wet beans from coffee skin. The dual action of shearing and squeezing improves the peeling rate of fresh coffee fruit.
[0052] The sorting unit uses a cage-type sorting system with auxiliary pressure. A mixture containing unpeeled fresh coffee cherries, green cherries, and peeled wet coffee beans enters the sorting screen. Under the interaction of the long, intermittent spiral and the sorting screen, the wet beans are separated from the pre-reserved holes on the screen, while the unpeeled fresh coffee cherries and green cherries are separated from the outlet at the tail end of the screen, thus completing the material grading and improving the quality of the coffee beans.
[0053] The degumming assembly employs an internal spray cleaning system. During the degumming process, a drive motor powers the rotation of a round steel bar, while internal water outlets enhance degumming efficiency and reduce water consumption. After degumming, the assembly can also be used to clean the inside of the degumming screen, keeping it clean and minimizing the impact of residual adhesive on subsequent batches.
[0054] The present invention adopts an integrated design for peeling, grading and degumming. It can be used in conjunction with a spectral color sorter and a water flotation desander for coffee cherries of different ripeness, thereby improving the versatility of the equipment and effectively removing various dried fruits, green fruits and other impurities that affect the quality of coffee from fresh coffee cherries of different ripeness.
[0055] During the whole machine's peeling and degumming process, a flexible peeling and degumming technology is adopted: rubber blocks are set in sections on the peeling blade channel of the peeling component to effectively reduce damage to the wet coffee beans during the peeling process; during the degumming process, internal water spraying is used to lubricate the hard friction between the wet coffee beans and between the coffee beans and the degumming screen, effectively reducing damage to the coffee beans during the degumming process.
[0056] The specific working principle is as follows:
[0057] In operation, fresh coffee cherries are first temporarily placed in the feed hopper 11. Initially, the cherries are blocked by the limiting plate of the limiting device 12. By adjusting the handle, the limiting plate is moved, creating a gap that allows the cherries to fall into the cone of the peeling mechanism 2. The motor on the integrated machine is then started, and after transmission, the peeling rotating shaft 23 rotates. A bevel gear at one end of the shaft drives a transmission gear 24, which in turn drives a transmission shaft 25. The transmission shaft 25 then drives the cone to rotate, which in turn rotates the sieve outside the cone, causing it to... The coffee cherries rub against the raised parts of the sieve, achieving a preliminary peeling effect. The cherries then enter the conveying pipe outside the conveying screw 3. The rotation of the central shaft 31 of the drum drives the screw 32 on its outer surface to rotate, thus conveying the peeled coffee cherries to the sorting screen 41. Finally, the peeled coffee cherries fall from the sorting screen 41 into the gap between the drum 51 and the second peeling blade 53, where they undergo further friction for a second peeling effect. Unripe cherries mixed in are then removed. The coffee beans, unable to fall through the sorting screen 41, are gradually driven by the guide plate 33 to the leftmost end of the conveying screw 3. Due to the cover plate counterweight 43, lighter coffee beans or husks cannot push against the cover plate, while heavier unripe coffee cherries can push against the cover plate counterweight 43 and exit through the unripe cherry outlet chute 42. Subsequently, the rotation of the roller 51 drives the screen 52 to rotate, which in turn drives the second peeling blade 53 to rotate, further rubbing the outer surface of the coffee beans and causing the pulp to detach further. This results in whole coffee beans being conveyed to the feed pipe. After entering the housing of the degumming mechanism 6, the coffee beans are rinsed. The drive motor on the degumming mechanism 6 can be adjusted by the motor adjustment device 64, which drives the central shaft rotating assembly 61 to rotate. The top of the central shaft rotating assembly 61 can be connected to a water source. After the water enters the central shaft rotating assembly 61, it is discharged from the water outlet of the round steel 611. In this way, the coffee beans can be rinsed. The multiple round steels 611 can rub the coffee beans. During the rinsing and rubbing process, the gum on the outer surface of the coffee beans can be removed, so that the coffee beans are no longer sticky. Finally, the coffee beans are discharged from the degumming discharge hopper 62.
