In particular, the popular Yunnan "small-grain coffee" in recent years has been in short supply. The primary processing of fresh coffee berries directly affects the overall flavor of coffee, so higher requirements are placed on the processing equipment of fresh coffee berries.

[0003] The existing coffee peeling and degumming machines are mainly realized in the form of a combination of a peeling device and a degumming device, which has the problems of being unable to separate green berries, equipment connection, high breakage rate and large space.

[0008] Through the above technical scheme, by putting the fresh coffee fruits into the feed barrel for temporary storage, the fresh coffee fruits will be blocked by the limit plate of the limiting device in the initial state, and the fresh coffee fruits are in the feed barrel. By adjusting the handle to drive the limit plate to move, the limit plate opens a gap to allow the fresh coffee fruits to slide from the feed barrel to the guide chute, and finally slide into the channel of the first peeling tool of the peeling mechanism. The size of the gap is adjusted by driving the limit plate to adjust the position by the handle, and then the speed at which the fresh coffee fruits fall into the cone of the peeling mechanism can be adjusted.

The overall structure can separate the green fruits and coffee beans.

The outer surface of the drum 51 is provided with a sieve 52, and the surface of the sieve 52 is provided with a plurality of protrusions.

[0033] Specifically, a feed pipe 66 is provided on the outer surface of the degumming mechanism 6, and the feed pipe 66 is connected to the left end of the secondary dehulling and pre-degumming mechanism 5 by bolts. The advantage is that when the coffee beans after secondary dehulling enter the feed pipe 66, a conveying auger is provided in the feed pipe 66, which can convey the coffee beans after secondary dehulling to the shell of the degumming mechanism 6, and the central axis rotating assembly 61 can rotate under the drive of the driving motor and the belt, thereby conveying the coffee beans entering the shell of the degumming mechanism 6 upward.

[0036] The peeling component of the present invention adopts oblique knife spiral peeling. Under the interaction between the material and the peeling knife in the conical barrel, the material moves obliquely downward in the spiral, and is sheared and squeezed multiple times in the first peeling knife channel to complete the separation of wet coffee beans and coffee skins. The dual effects of shearing and squeezing improve the peeling rate of fresh coffee fruits.

[0037] The sorting component adopts a squirrel cage sorting with auxiliary pressure. A mixture of 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 reserved waist holes on the sorting screen, while the unpeeled fresh coffee cherries and green cherries are separated from the outlet at the tail end of the sorting screen, completing the material grading and improving the quality of coffee beans.

[0038] The degumming component adopts internal spray cleaning degumming. During the degumming process, the driving motor provides power to drive the round steel to rotate and rub. At the same time, water outlets are set inside to improve the degumming efficiency and reduce water consumption. After the degumming is completed, it can also be used to clean the inside of the degumming screen to keep the screen clean and reduce the impact of residual colloid on the next batch.

[0039] The whole machine of the present invention adopts an integrated design of peeling, grading and degumming. It can be used in conjunction with a spectral color sorter and a water flotation separator for coffee berries of different maturity levels, thereby improving the versatility of the equipment and effectively removing various impurity beans that affect coffee quality, such as various dried fruits and green fruits in coffee berries of different maturity levels.

[0040] During the peeling and degumming process of the whole machine, flexible peeling and degumming technology is adopted: rubber blocks are set in different areas on the peeling knife channel of the peeling component to effectively reduce the damage to the wet coffee beans during the peeling process; during the degumming process, internal spray water is used to lubricate the hard friction between the wet coffee beans and between the coffee beans and the degumming screen, effectively reducing the damage to the coffee beans during the degumming process.

[0041] The specific working principle is: When in use, firstly, fresh coffee fruits are put into the feed barrel 11 for temporary storage. In the initial state, the fresh coffee fruits will be blocked by the limit plate of the limit device 12. By adjusting the handle to drive the limit plate to move, the limit plate opens a gap to allow the fresh coffee fruits to fall into the cone of the peeling mechanism 2. The motor on the integrated machine is started, and after transmission, the peeling rotating shaft 23 rotates, and then the bevel gear at one end drives the transmission gear 24 to rotate, and the transmission gear 24 drives the transmission shaft 25 to rotate, and the transmission shaft 25 drives the cone to rotate, and after the cone rotates, it drives the sieve outside to rotate, so that The coffee fruits are rubbed against the raised part of the sieve, and then the coffee fruits are initially peeled. Then the coffee fruits enter the conveying pipe arranged outside the conveying screw 3. The rotation of the central axis 31 of the drum can drive the spiral 32 on its outer surface to rotate, so that the fresh coffee fruits after the first peeling can be conveyed to the sorting screen 41. Finally, the fresh coffee fruits after the peeling fall from the sorting screen 41 and enter the gap between the drum 51 and the second peeling knife 53. The coffee fruits are rubbed again to achieve the effect of secondary peeling. The green fruits mixed therein are The coffee beans are too big 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. Due to the cover plate counterweight 43, the lighter coffee beans or coffee skins cannot push the cover plate, while the heavier green coffee berries can push the cover plate counterweight 43 and be discharged from the green berries outlet slide 42. Then, the screen 52 is driven to rotate by the rotation of the drum 51, and the screen 52 drives the second peeling knife 53 to rotate to further rub the outer surface of the coffee beans, so that the pulp on the outer surface of the coffee beans is further separated, so that the complete coffee beans are conveyed to the feeding pipe. After entering the degumming mechanism 66, the driving motor on the degumming mechanism 6 can be adjusted by the motor adjusting device 64 to drive the central axis rotating component 61 to rotate. The top of the central axis rotating component 61 can be connected to a water source. After entering the central axis rotating component 61, the water is discharged from the water outlet hole of the round steel 611, so that the coffee beans can be rinsed, and the multiple round steels 611 can rub the coffee beans. The colloid on the outer surface of the coffee beans can be removed during the rinsing and rubbing process, so that the coffee beans are no longer sticky. Finally, the coffee beans are discharged from the degumming hopper 62.
