Description

Technical Field

[0001] This utility model relates to the field of coffee production technology, and in particular to a coffee bean cleaning device for coffee production. Background Technology

[0002] Coffee is a caffeinated beverage made from the seeds (coffee beans) of plants belonging to the Rubiaceae family and the Coffee genus. Its production process includes planting, harvesting, processing, roasting, and brewing. After harvesting, the coffee cherries need to be processed to remove the pulp and outer shell. The main methods include the washed method (removing pulp and mucilage through soaking and fermentation), the sun-drying method (drying the whole fruit before shelling), and the honey treatment (partially retaining pectin). Different processes significantly affect the acidity and flavor of the finished product. After processing, the green beans need to be washed to remove pulp residue, dirt, and other impurities.

[0003] Currently, bubble washing machines are commonly used to clean dirt and other impurities from raw soybeans. They utilize the tumbling of bubbles to achieve cleaning and mainly consist of a washing tank, an aeration system, and a conveying device. The aeration system uses an air pump to generate high-pressure air, which is released through aeration pipes to create turbulence, causing the material to tumble and separating impurities. The conveying device uses a motor-driven conveyor belt to smoothly transport the material through the washing zone, achieving automatic loading and unloading.

[0004] However, during the cleaning process using a bubble washing machine, it is inconvenient to collect defective beans (such as empty shells and immature beans) floating on the water surface, causing them to accumulate in the washing tank and affecting the normal cleaning process. Moreover, the existing aeration pipes are usually fixed in the washing tank, which can cause excessive aeration in some areas while insufficient aeration in others, forming "dead zones" and affecting the overall cleaning effect. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art of inconvenient collection of floating defective beans and poor aeration effect due to the fixed aeration pipe, and to propose a coffee bean cleaning device for coffee production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coffee bean cleaning device for coffee production includes a housing with a cleaning tank inside. A conveyor belt is installed in the cleaning tank. The device also includes at least one set of collection nets for collecting floating defective beans, which spans across the cleaning tank and moves along a preset trajectory. A collection frame that cooperates with the collection nets is installed in the cleaning tank. Multiple sets of aeration pipes are equidistantly distributed along the length of the housing and are all installed in the cleaning tank. A drive unit is provided on the housing for driving the aeration pipes to swing.

[0008] To facilitate driving the collection net, preferably, a pair of sprockets are provided on both sides of the washing tank. The pair of sprockets are driven by meshing chains, and at least one set of crossbars is fixedly provided between the two pairs of chains. The collection net is fixedly provided on the crossbars, and the collection net moves along the elliptical path formed by the chains.

[0009] To facilitate the rotation of the sprockets, the driving wheels of the two pairs of sprockets are coaxially and fixedly connected by a fixed shaft, and a first pulley is fixedly installed at one end of the fixed shaft extending out of the housing. A motor is fixedly installed on one side of the housing, and a second pulley is fixedly installed at the output end of the motor. The first pulley and the second pulley are driven by a synchronous belt.

[0010] In order to drive multiple sets of aeration pipes to swing simultaneously, preferably, the driving unit includes two guide frames fixedly disposed on one side of the box, a fixed plate slidably disposed between the two guide frames, a rack fixedly disposed at the bottom of the fixed plate, and gears fixedly disposed on one end of each of the aeration pipes extending out of the box, and the multiple gears meshing with the rack. When the rack slides back and forth along the material movement direction, the gears drive the aeration pipes to swing back and forth.

[0011] Furthermore, a cylinder is fixedly mounted on one of the guide frames, the output end of the cylinder is fixedly connected to the top of the fixed plate, and the sliding direction of the fixed plate is parallel to the extension and retraction direction of the cylinder output end.

[0012] Furthermore, the inner walls at both ends of the cleaning tank are fixedly provided with first baffles in an arc shape. The end of the collecting net bag away from the crossbar abuts against the inner wall of the first baffle. The bottom plane of the two sets of first baffles is lower than the liquid level in the cleaning tank. A second baffle is fixedly provided on the outer wall of one set of first baffles. The second baffle is close to the end of the cleaning tank where the material is fed.

[0013] Preferably, a mesh screen is fixedly installed on the inner wall of the collection frame to hold the defective beans that have been poured out of the collection net.

[0014] Preferably, a diversion box is fixedly installed on one side of the box body, and one end of each of the multiple aeration pipes extending out of the box body is connected to the inside of the diversion box, and a sealing ring is fixedly installed on the connection surface between the diversion box and the aeration pipe.

[0015] Compared with the prior art, the present invention provides a coffee bean cleaning device for coffee production, which has the following beneficial effects:

[0016] 1. This coffee bean washing device for coffee production uses a collection net that moves within the washing tank to collect floating defective beans during the washing process. The collected beans are then poured into a collection box, reducing the accumulation of defective beans in the washing tank and minimizing their adverse effects on the washing process. Furthermore, multiple sets of aeration pipes oscillate within the washing tank, providing a relatively uniform air distribution over a wide area. This ensures that all coffee beans in the water body come into contact with sufficient air bubbles, effectively reducing "dead zones" within the tank and preventing coffee beans in certain areas from not being thoroughly washed, thus improving the washing effect.

[0017] 2. The coffee bean cleaning device for coffee production has support grooves on the inner walls of two sets of second support plates, and support blocks are fixedly installed on both sides of the collection frame. The support blocks are slidably installed in the support grooves, which can support and limit the collection frame. Moreover, it is easy to install and disassemble, and facilitates the subsequent processing of the material collected in the collection frame to improve the use effect.

[0018] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model, by moving a collection net bag inside the washing tank, can collect floating defective beans during the washing process, and then pour the collected beans into a collection frame, reducing the accumulation of defective beans in the washing tank and minimizing their adverse effects on the washing process. In addition, multiple sets of aeration pipes swing inside the washing tank, which can effectively reduce "dead zones" in the tank, preventing coffee beans in certain areas from not being fully cleaned and improving the washing effect.

[0026] Example:

[0027] Reference Figures 1-4A coffee bean cleaning device for coffee production includes a housing 1, within which a cleaning tank is formed, shaped like an inverted isosceles trapezoid. An inlet pipe and a drain pipe are fixedly installed at one end of the cleaning tank, both equipped with valves for easy water replacement. A conveyor belt 101, also approximately inverted isosceles trapezoidal in shape (inclined upwards at both ends), is installed within the cleaning tank. When the conveyor belt 101 rotates to transport the material, it moves the material from a higher position at one end to a flat position at the bottom, and then outputs it from the other end. The conveyor belt 101 has grid strips fixedly installed to facilitate the transport of coffee beans. A drive mechanism for operating the conveyor belt 101 is installed on the housing 1. Both the conveyor belt 101 and the drive mechanism are existing technologies and will not be described here. The device also includes at least one set of collection nets 301 for collecting floating defective beans, spanning the cleaning tank. The system moves along a preset trajectory. Here, we have set two sets of collection nets 301, which are similar to the bucket of an excavator to facilitate the collection of defective beans floating in the washing tank. A collection frame 4 that works with the collection nets 301 is set in the washing tank. During use, the collection nets 301 collect along the collection path. When they move to the dumping path, they can dump the collected material into the collection frame 4 for easy collection next time. A first mesh is fixedly set on the inner wall of the collection frame 4 to hold the defective beans dumped by the collection nets 301. When the beans fall, they will land on the first mesh, which can cushion the beans and reduce the possibility of splashing. Furthermore, a second mesh is fixedly set inside the collection frame 4, extending along the depth direction of the collection frame 4. Multiple second meshes are set at equal intervals, preferably five, and they are tilted to improve the interception of splashed beans. The bottom of the collection frame 4 is mesh-like to reduce water accumulation in the collection frame 4 and improve the use effect.Multiple sets of aeration pipes 5 are equidistantly distributed along the length of the housing 1, and are oscillatingly arranged within the cleaning tank. There are two to twenty sets of aeration pipes 5; here, we preferably have seventeen sets. Each set of aeration pipes 5 has five aeration nozzles equidistantly arranged at one end within the cleaning tank. A distribution box 502 is fixedly installed on one side of the housing 1, connecting the ends of the multiple aeration pipes 5 extending out of the housing 1 to the distribution box 502. An air inlet pipe is fixedly installed on the distribution box 502, allowing high-pressure air to enter the distribution box 502 through the air inlet pipe and then be distributed to each set of aeration pipes 5. To ensure… To ensure the sealing effect of the aeration pipe 5 during its swing, a sealing ring is fixedly installed at the connection surface between the distribution box 502 and the aeration pipe 5. Similarly, a sealing ring is also installed at the connection surface between the box body 1 and the aeration pipe 5. A drive unit for driving the aeration pipe 5 to swing is installed on the box body 1. During use, by driving multiple sets of aeration pipes 5 to swing back and forth during the cleaning process, a relatively uniform air distribution can be provided over a large area, ensuring that all coffee beans in the water body come into contact with sufficient air bubbles. This effectively reduces "dead zones" in the pool, prevents coffee beans in certain areas from not being thoroughly cleaned, and improves the cleaning effect.

[0028] During use, a collection net 301 is installed and moved within the washing tank to collect floating defective beans during the washing process. The collected beans are then poured into a collection frame 4, reducing the accumulation of defective beans in the washing tank and minimizing their adverse effects on the washing process. Furthermore, multiple sets of aeration pipes 5 oscillate within the washing tank, providing a relatively uniform air distribution over a wide area. This ensures that all coffee beans in the water can come into contact with sufficient air bubbles, effectively reducing "dead zones" within the tank and preventing coffee beans in certain areas from not being thoroughly cleaned, thus improving the washing effect.

[0029] Reference Figures 1-3A pair of sprockets 2 are installed on both sides of the washing tank. Each pair of sprockets 2 consists of a driving wheel and a driven wheel. The sprockets 2 are driven by chains 201. At least one set of crossbars 3 is fixed between the two sets of chains 201. Here, we set two sets of crossbars 3, each corresponding to a collection net 301. The collection net 301 is fixedly installed on the crossbars 3. The collection net 301 moves along a preset elliptical trajectory formed by the chains 201. That is, the collection net 301 can move along the elliptical path following the chains 201. Here, we define the collection stage as the direction in which the collection net 301 is in the same direction as the material conveyed by the conveyor belt 101. At this time, the collection net 301 moves from the driving wheel to the driven wheel at the bottom of the elliptical path. When the collection net 301 rises along the arc and completely flips over, the material collected in the collection net 301 can be poured into the collection frame 4. To facilitate continued collection and further improve the conveying effect of the chain 201, a tensioning wheel is fixedly installed on the end of the housing 1 near the drive wheel to tension the chain 201 and keep it as taut as possible. A first support plate 203 and a second support plate 204 are fixedly installed at both ends of the housing 1. The drive wheel is rotatably connected to the first support plate 203, and the driven wheel is rotatably connected to the second support plate 204. Two sets of the first support plate 203 and the second support plate 204 are symmetrically arranged. Support grooves 205 are opened on the inner walls of the two sets of second support plates 204. Support blocks 401 are fixedly installed on both sides of the collection frame 4. The support blocks 401 are slidably installed in the support grooves 205 to support and limit the collection frame 4. They are also easy to install and remove, which facilitates the subsequent processing of the materials collected in the collection frame 4 and improves the utilization effect.

[0030] Reference Figure 3 The driving wheels of two pairs of sprockets 2 are coaxially and fixedly connected by a fixed shaft. A first pulley 202 is fixedly installed at one end of the fixed shaft extending out of the box 1. A motor is fixedly installed on one side of the box 1, and a second pulley 206 is fixedly installed at the output end of the motor. The first pulley 202 and the second pulley 206 are driven by a synchronous belt. In use, the motor is started to drive the second pulley 206 to rotate, and then the first pulley 202 is driven to rotate through the synchronous belt. This can drive the driving wheels of the fixed shaft and sprockets 2 to rotate, thereby driving the collection net 301 to collect the floating beans.

[0031] Reference Figure 2The drive unit is designed with two guide frames fixedly installed on one side of the housing 1. A fixed plate 6 is slidably installed between the two guide frames. A rack 601 is fixedly installed at the bottom of the fixed plate 6. The cross-section of the fixed plate 6 and the rack 601 is T-shaped. T-slots are provided on the guide frames to facilitate the reliable sliding of the fixed plate 6 and prevent it from falling off. Gears 501 are fixedly installed on one end of each of the multiple aeration pipes 5 extending out of the housing 1. All gears 501 mesh with the rack 601. When the rack 601 slides back and forth along the material movement direction, the gears 501 drive the aeration pipes 5 to swing back and forth. A cylinder 7 is fixedly installed on one of the guide frames. The output end of the cylinder 7 is fixedly connected to the top of the fixed plate 6, and the sliding direction of the fixed plate 6 is parallel to the extension and retraction direction of the output end of the cylinder 7. By starting the cylinder 7, the fixed plate 6 and the rack 601 can be driven to slide back and forth, thereby driving multiple sets of aeration pipes 5 to swing back and forth, improving the usage effect.

[0032] Reference Figure 1 , Figure 3 and Figure 4 A first baffle 102 with an arc-shaped structure is fixedly installed on the inner wall of both ends of the washing tank. The end of the collecting net 301 away from the crossbar 3 is abutted against the inner wall of the first baffle 102. That is to say, when the collecting net 301 is rotated along the elliptical lake edge, the outermost rotation path matches the arc of the inner wall of the first baffle 102, which can improve the collection effect of defective beans. In addition, the bottom plane of the two sets of first baffles 102 is lower than the liquid level in the washing tank. A second baffle 103 is fixedly installed on the outer wall of one set of first baffles 102. The second baffle 103 is close to the feeding end of the washing tank. During use, it can reduce the flow of defective beans from the output end of the conveyor belt 101 and the dead corner of the collecting net 301, thereby improving the collection effect.

[0033] In this invention, during use, coffee beans are fed into the input end of the conveyor belt 101. As the conveyor belt 101 carries the coffee beans towards the output end of the washing tank, they pass through the bubble cleaning zone of the washing tank. At this time, the aeration pipe 5 swings back and forth to aerate, which can improve the cleaning effect. Then, the collection net 301, driven by the chain 201, can collect the defective beans floating on the horizontal surface and finally pour them into the collection frame 4, reducing the adverse effects on the cleaning effect of normal beans, reducing the time spent on manual collection and sorting, and improving the usage effect.

[0034] 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.
