Description

Technical Field

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

[0002] Coffee is an indispensable beverage for modern people, and the most important raw material for its rich and flavorful taste is the coffee bean. These are the seeds of the coffee tree, a small shrub that grows in cold, low-lying areas. Its fruit is white or yellow, and the seeds on the outside are the original form of the coffee bean.

[0003] Chinese Patent Publication No. CN209031169U discloses a coffee bean separation and rinsing device, including a box body and a box cover. A motor is fixedly installed on the top of one side of the box body, and a vibrator is fixedly installed in the middle of the side of the box body. The interior of the box body is divided into a first inner cavity and a second inner cavity by a partition. A spray pipe is fixedly installed on the top of the inner wall of the first inner cavity, and several nozzles are evenly installed at the bottom of the spray pipe. A rectangular tube is fixedly installed in the middle of the inner wall of the first inner cavity, and several rinsing tubes are evenly installed at the bottom of the rectangular tube. The above-mentioned coffee bean separation and rinsing device uses a motor to drive a fixed cylinder on a rotating shaft to rotate, which in turn drives a mesh cylinder to rotate. During the rotation, the spray nozzles installed at the bottom of the spray pipe spray and rinse the beans. The rotation of the mesh cylinder and the spray nozzles work together to better separate the fruit skin and coffee beans. Then, the coffee beans are rinsed and separated from the pectin through the rinsing tubes, making the rinsing more complete and improving the rinsing quality of the coffee beans.

[0004] However, the coffee bean separation and rinsing device described in the aforementioned patent literature uses a rinsing method. During the rinsing process, coffee beans release various substances, including aromatic components, pectin, pesticide residues (if pesticides were used), and other possible impurities. These substances dissolve in the water, making the rinsing water impure. The aforementioned device recycles the used water and continues rinsing, which results in subsequent coffee beans not being properly cleaned, and rinsing also fails to separate immature coffee beans. Utility Model Content

[0005] The main purpose of this invention is to provide a coffee bean separation and rinsing device that can effectively solve the problems of incomplete cleaning and inability to screen coffee beans.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A coffee bean separation and rinsing device includes a main body, a lifting assembly fixedly connected to the inner cavity of the main body, a cooperating assembly fixedly connected to the inner cavity of the main body, a driving assembly fixedly connected to the lower part of the cooperating assembly, and a separation assembly rotatably connected to the front part of the main body.

[0008] Preferably, the main body includes an outer shell, with support legs fixedly connected to the four corners of the lower end of the outer shell, a water inlet pipe fixedly connected to the rear end of the outer shell, and a water outlet pipe fixedly connected to the right end of the outer shell.

[0009] Preferably, the lifting assembly includes an electric telescopic rod, the lower end of which is fixedly connected to the bottom wall of the inner cavity of the outer shell, a rotating disk is rotatably connected to the upper end of the electric telescopic rod, a filter cylinder is rotatably connected to the outer surface of the rotating disk, and a stirring rod is fixedly connected to the upper end of the rotating disk.

[0010] Preferably, the mating assembly includes a partition plate, the four ends of which are fixedly connected to the four side walls of the inner cavity of the outer shell, and a pulley is rotatably connected to the upper end of the partition plate. The upper left and right parts of the pulley are provided with mating grooves.

[0011] Preferably, the drive assembly includes a motor, the upper end of which is fixedly connected to the lower end of the isolation plate, and the output end of the motor is fixedly connected to a second pulley via a coupling. The outer surface of the second pulley and the outer surface of the first pulley are together wound with a first belt, and the upper end of the second pulley is fixedly connected to a first bevel gear via a shaft.

[0012] Preferably, the separation assembly includes a third pulley, the rear end of which is rotatably connected to the front end of the housing. A second bevel gear is fixedly connected to the rear end of the third pulley via a shaft. A fourth pulley is rotatably connected to the upper part of the front end of the housing. A second belt is wound around the outer surfaces of the third and fourth pulleys. A reciprocating screw is fixedly connected to the rear end of the fourth pulley. A guide rod is fixedly connected to the front and rear side walls of the inner cavity of the housing. A sliding plate is slidably connected to the outer surface of the reciprocating screw and the outer surface of the guide rod.

[0013] Preferably, the lower end of the second pulley is rotatably connected to the upper end of the isolation plate, and the outer surface of the first bevel gear and the outer surface of the second bevel gear are meshed together.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its lifting component, cooperating component, and driving component, enables the stirring rod to quickly agitate in water, allowing the coffee beans to fully contact the water. The combined effect of the water flow's impact and the stirring rod's mechanical force can more quickly remove dust, impurities, and residual pulp and pectin from the surface of the coffee beans. Moreover, compared to some powerful cleaning methods such as high-pressure water jet rinsing, the stirring rod's cleaning process allows the coffee beans to rub against each other and against the water in a gentler way, reducing the possibility of surface damage or internal structural damage to the coffee beans due to excessive external force. This better preserves the original flavor and quality of the coffee beans. Furthermore, the stirring rod also stirs out immature coffee beans, separating them from the water.

[0016] 2. This invention, through its designed drive and separation components, allows for the separation of immature coffee beans. The remaining mature coffee beans are then heated more evenly during roasting, thus improving the quality of the final coffee product. This results in a more consistent taste and flavor in every cup. Immature coffee beans often have unpleasant flavors such as sourness, astringency, and grassiness. If not separated, these undesirable flavors will infuse into the coffee during brewing, affecting the overall flavor balance. Separating them prevents these negative flavors from interfering, resulting in a richer, smoother, and more complex flavor profile, highlighting the inherent fruity, nutty, and chocolate aromas of the coffee beans.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 As shown, a coffee bean separation and rinsing device includes a main body 1, a lifting component 2 fixedly connected to the inner cavity of the main body 1, a mating component 3 fixedly connected to the inner cavity of the main body 1, a driving component 4 fixedly connected to the lower part of the mating component 3, and a separation component 5 rotatably connected to the front part of the main body 1.

[0026] When implementing this solution, the operator first adds water into the main body 1 and starts the lifting component 2 to rise. Then, the operator puts coffee beans into the lifting component 2 and starts the lifting component 2 to descend. At this time, the coffee beans will be soaked in water, so some immature coffee beans will float to the surface. After the lifting component 2 descends and overlaps with the cooperating component 3, the operator starts the drive component 4. The drive component 4 will make the lifting component 2 rotate, thereby stirring the coffee beans. Thus, while cleaning the coffee beans, the positions of the coffee beans are also disrupted, so another part of the immature coffee beans that have not been separated will float to the surface.

[0027] At the same time, the drive component 4 will also drive the separation component 5 to rotate, thereby causing the separation component 5 to scrape the coffee beans to the outside, thus achieving the effect of separating the coffee beans while cleaning them. After the coffee beans are cleaned, the operator will let the separation component 5 stick tightly to the inner wall of the main body 1 and then turn off the drive component 4, and then start the lifting component 2 to rise. The operator can then take out the cleaned coffee beans and then discharge the wastewater from the main body 1.

[0028] Specifically, in order to clean coffee beans, such as Figure 1 As shown, in this scheme, the main body 1 includes a shell 11, and support legs 12 are fixedly connected to the four corners of the lower end of the shell 11. A water inlet pipe 13 is fixedly connected to the rear end of the shell 11, and a water outlet pipe 14 is fixedly connected to the right end of the shell 11.

[0029] For further details, please refer to [link / reference]. Figure 2 , Figure 4 and Figure 6 The lifting assembly 2 includes an electric telescopic rod 21. The lower end of the electric telescopic rod 21 is fixedly connected to the bottom wall of the inner cavity of the outer shell 11. The upper end of the electric telescopic rod 21 is rotatably connected to a rotating disk 23. A filter cylinder 22 is rotatably connected to the outer surface of the rotating disk 23. A stirring rod 24 is fixedly connected to the upper end of the rotating disk 23.

[0030] For further details, please refer to [link / reference]. Figure 3 and Figure 6 The mating component 3 includes an isolation plate 31. The four ends of the isolation plate 31 are fixedly connected to the four side walls of the inner cavity of the outer shell 11. A pulley 32 is rotatably connected to the upper end of the isolation plate 31. The upper left and right sides of the pulley 32 are provided with mating grooves 33.

[0031] For further details, please refer to [link / reference]. Figure 2 and Figure 5 The drive assembly 4 includes a motor 41, the upper end of which is fixedly connected to the lower end of the isolation plate 31. The output end of the motor 41 is fixedly connected to a pulley 42 via a coupling. A belt 43 is wound around the outer surface of the pulley 42 and the outer surface of the pulley 32. A bevel gear 44 is fixedly connected to the upper end of the pulley 42 via a shaft.

[0032] For further details, please refer to [link / reference]. Figure 5 The lower end of pulley 42 is rotatably connected to the upper end of isolation plate 31.

[0033] In implementation, the operator first adds water to the inside of the outer casing 11 through the water inlet pipe 13, and then activates the electric telescopic rod 21 to raise the rotating disk 23, filter cartridge 22, and stirring rod 24. After the operator puts coffee beans into the filter cartridge 22, the electric telescopic rod 21 is activated to lower it. At this time, the coffee beans will be soaked in water, and some immature coffee beans will float to the surface. Afterwards, when the rotating disk 23 lowers and aligns with the mating groove 33, the operator activates the motor 41 to drive the pulley 42, belt 43, pulley 32, rotating disk 23, and stirring rod 24 to rotate, thereby stirring the coffee beans. In this way, while cleaning the coffee beans, the positions of the coffee beans are also disrupted, so another part of the immature coffee beans that have not been separated will float to the surface.

[0034] Example 2, which is based on Example 1, allows for the separation of immature coffee beans.

[0035] Specifically, in order to separate immature coffee beans, such as Figure 3 and Figure 5As shown, in this scheme, the separation component 5 includes a pulley 3 51, the rear end of which is rotatably connected to the front end of the housing 11. A bevel gear 2 52 is fixedly connected to the rear end of the pulley 3 51 via a shaft. A pulley 4 54 is rotatably connected to the upper part of the front end of the housing 11. A belt 2 55 is wound around the outer surfaces of the pulley 3 51 and the outer surfaces of the pulley 4 54. A reciprocating screw 53 is fixedly connected to the rear end of the pulley 4 54. A guide rod 56 is fixedly connected to the front and rear side walls of the inner cavity of the housing 11. A sliding plate 57 is slidably connected to the outer surfaces of the reciprocating screw 53 and the guide rod 56.

[0036] For further details, please refer to [link / reference]. Figure 5 The outer surface of bevel gear 1 (44) and the outer surface of bevel gear 2 (52) mesh with each other.

[0037] During implementation, pulley 2 42 will simultaneously drive bevel gear 1 44, bevel gear 2 52, pulley 3 51, belt 2 55, pulley 4 54 and reciprocating screw 53 to rotate, thereby causing the sliding plate 57 to slide on the guide rod 56 to scrape the coffee beans to the outside, thus achieving the effect of cleaning and separating the coffee beans at the same time. After cleaning the coffee beans, the operator will make the sliding plate 57 stick tightly to the inner wall of the outer casing 11 and then turn off the motor 41, and then start the electric telescopic rod 21 to rise. The operator can then take out the cleaned coffee beans and then discharge the wastewater from the outlet pipe 14.

[0038] The sliding plate 57 has a latch that can slide within the groove of the reciprocating lead screw 53.

[0039] In summary, the implementation process of this utility model is as follows:

[0040] The operator first adds water into the housing 11 through the water inlet pipe 13, and then activates the electric telescopic rod 21 to raise the rotating disc 23, filter cartridge 22 and stirring rod 24. After the operator puts coffee beans into the filter cartridge 22, the electric telescopic rod 21 is activated to lower the coffee beans. At this time, the coffee beans will be soaked in water, and some unripe coffee beans will float to the surface. After the rotating disc 23 lowers and aligns with the mating groove 33, the operator activates the motor 41 to drive the pulley 42, belt 43, pulley 32, rotating disc 23 and stirring rod 24 to rotate, thereby stirring the coffee beans. In this way, while cleaning the coffee beans, the positions of the coffee beans are also disrupted, so another part of the unseparated unripe coffee beans will float to the surface.

[0041] At the same time, pulley 2 42 will drive bevel gear 1 44, bevel gear 2 52, pulley 3 51, belt 2 55, pulley 4 54 and reciprocating screw 53 to rotate, thereby causing the sliding plate 57 to slide on the guide rod 56 to scrape the coffee beans to the outside, thus achieving the effect of cleaning and separating the coffee beans at the same time. After cleaning the coffee beans, the operator will make the sliding plate 57 stick tightly to the inner wall of the outer casing 11 and then turn off the motor 41, and then start the electric telescopic rod 21 to rise. The operator can then take out the cleaned coffee beans and then discharge the wastewater from the outlet pipe 14.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the electric telescopic rod 21 and motor 41 used in this utility model are all conventional designs, and will not be described in detail in this utility model.
