Description
Technical Field
[0001] This utility model belongs to the field of coffee bean production technology, specifically a coffee bean fermentation device. Background Technology
[0002] Coffee beans are the seeds of the coffee tree and the main ingredient in making coffee. The coffee tree belongs to the Rubiaceae family and originated in tropical Africa, but is now cultivated in many places. The ripe coffee fruit is red and called a coffee cherry; the seeds inside are the coffee beans. Usually, a coffee cherry contains two beans, but sometimes it may contain only one, called "pea coffee."
[0003] In existing technologies, coffee bean fermentation is a key step in the processing of green coffee beans. Its main purpose is to separate the slippery mucilage covering the inner pericarp. A suitable fermentation environment also improves the taste and quality of coffee.
[0004] Long-term observation revealed that preventing coffee beans from spoiling during the fermentation process is crucial. However, most current coffee bean fermentation equipment requires manual disinfection and cleaning of the inside of the equipment after fermentation, which increases the workload of staff and reduces work efficiency.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 4 As shown, a coffee bean fermentation device according to an embodiment of the present invention includes a cleaning chamber 1; a pair of support plates 11 are fixed to the top of the cleaning chamber 1; the pair of support plates 11 are symmetrically arranged on both sides of the cleaning chamber 1; support rods 12 are fixed to the top of the support plates 11; an electric push rod 13 is assembled between the pair of support rods 12; a push plate 14 is fixed to the output end of the electric push rod 13; a first upright plate 15 is fixed to the bottom of the push plate 14; a second upright plate 16 is fixed to the bottom of the push plate 14; the first upright plate 15 and the second upright plate 16 are correspondingly arranged; a fermentation tank 17 is soaked inside the cleaning chamber 1; a fixing component is provided between the first upright plate 15 and the second upright plate 16, which can fix the fermentation tank 17 between the first upright plate 15 and the second upright plate 16; a rotating component is provided in the middle of the side wall of the second upright plate 16, which will rotate the fermentation tank 17 inside the cleaning chamber 1; a rinsing component is provided in the middle of the inner side wall of the fermentation tank 17, which will clean the inside of the fermentation tank 17 when it rotates; cleaning A cleaning component is installed in the middle of the inner wall of the tank 1. This cleaning component cleans the exterior of the fermentation tank 17 when it rotates. During operation, the operator injects cleaning liquid into the cleaning tank 1, and then uses the fixing component to fix the used fermentation tank 17 between the first upright plate 15 and the second upright plate 16. Then, the electric push rod 13 is activated, which pushes the push plate 14 downward. At this time, the push plate 14 will drive the first upright plate 15, the second upright plate 16 and the fermentation tank 17 to move downward at the same time, so that the fermentation tank 17 is completely immersed in the cleaning liquid inside the cleaning tank 1. Then, the rotating component is activated, which rotates the fermentation tank 17, so that the fermentation tank 17 rotates in the cleaning liquid, so that the cleaning liquid completely covers all corners of the fermentation tank 17. At the same time, the flushing component will scrub the inner wall of the fermentation tank 17 when it rotates, and the cleaning component will scrub the outer wall of the fermentation tank 17 when it rotates. Under the combined action of the rotating component, the flushing component and the cleaning component, all corners of the fermentation tank 17 are cleaned.
[0026] like Figures 1 to 4As shown, the fixing assembly includes a telescopic rod 2; the telescopic rod 2 is rotatably connected to the side wall of the second upright plate 16; a first fixing plate 21 is fixed to the end of the telescopic rod 2; a fixing rod 22 is rotatably connected to the middle of the side wall of the first upright plate 15; a second fixing plate 23 is fixed to the end of the fixing rod 22; the fermentation tank 17 is located between the first fixing plate 21 and the second fixing plate 23; the rotating assembly includes a motor 24; the motor 24 is fixed to the side wall of the cleaning tank 1; the output end of the motor 24 is driven by a first synchronous belt 25; the middle of the inner side wall of the first synchronous belt 25 is driven by... A first movable shaft 26 is connected; the telescopic rod 2 and the first movable shaft 26 are fastened together; during operation, the operator pulls the first fixed plate 21 to place the fermentation tank 17 between the first fixed plate 21 and the second fixed plate 23, and then releases the first fixed plate 21. At this time, the first fixed plate 21 and the second fixed plate 23 will fix the fermentation tank 17, making it easy to immerse the fermentation tank 17 in the cleaning solution and remove it from the cleaning solution. When the fermentation tank 17 is completely immersed in the cleaning solution, the operator inserts the first movable shaft 26 into the telescopic rod 2. Inside, motor 24 is then started, which drives the first synchronous belt 25 to rotate. When the first synchronous belt 25 rotates, it drives the first movable shaft 26 to rotate, which in turn drives the telescopic rod 2 to rotate. This causes the telescopic rod 2 to drive the first fixed plate 21, the fixed rod 22, the second fixed plate 23, and the fermentation tank 17 to rotate simultaneously. At this time, the cleaning liquid will completely cover all corners of the fermentation tank 17. This step, by setting the telescopic rod 2, the first fixed plate 21, the fixed rod 22, and the second fixed plate 23, can quickly and accurately immerse the fermentation tank 17 in the cleaning liquid and automatically remove it after cleaning. The entire process does not require manual intervention, which improves work efficiency. By setting the motor 24, the first synchronous belt 25, and the first movable shaft 26 to rotate the fermentation tank 17, the cleaning liquid can penetrate more fully into all corners and gaps inside the tank, so that it can fully cover and remove dirt and residues from the surface of the fermentation tank 17. In addition, the centrifugal force generated during the rotation helps to loosen the stubborn dirt attached to the tank wall, making it easier to be dissolved and washed away by the cleaning liquid.
[0027] like Figures 1 to 4As shown, the flushing assembly includes an inlet pipe 3; the inlet pipe 3 is rotatably connected to the inside of the fixed rod 22; multiple outlets 31 are provided in the middle of the side wall of the inlet pipe 3; the outlets 31 are located inside the fermentation tank 17; multiple first cleaning brushes 32 are fixedly connected to the middle of the side wall of the inlet pipe 3; the first cleaning brushes 32 are located inside the fermentation tank 17; during operation, the operator inserts the inlet pipe 3 into the fixed rod 22. At this time, one end of the inlet pipe 3 is inside the fermentation tank 17. Because the inlet pipe 3 and the fixed rod 22 are rotatably connected, when the fermentation tank 17 rotates, the inlet pipe 3 and the multiple first cleaning brushes 32 on its side wall remain relatively stationary in the cleaning liquid, so that the multiple first cleaning brushes 32... A cleaning brush 32 scrubs the inner wall of the rotating fermentation tank 17 from the inside, while simultaneously injecting cleaning liquid into the inlet pipe 3 through the other end of the inlet pipe 3. At this time, the cleaning liquid flows into the fermentation tank 17 from multiple outlets 31, so that the cleaning liquid completely fills the interior of the fermentation tank 17. This step, by setting up the inlet pipe 3, outlets 31 and the first cleaning brush 32, can thoroughly clean every corner and crevice of the inner wall of the fermentation tank 17, more effectively removing stubborn stains and residues attached to the tank wall, such as pectin, sugar, yeast and other microorganisms, reducing areas that may be missed by traditional cleaning methods, thereby keeping the tank wall clean and smooth.
[0028] like Figures 1 to 4 As shown, the cleaning assembly includes a second synchronous belt 4; the second synchronous belt 4 is driven to the side wall of the first movable shaft 26; a second movable shaft 41 is driven to the middle of the inner side wall of the second synchronous belt 4; a fixed cylinder 42 is fixed to the middle of the side wall of the second movable shaft 41; a plurality of second cleaning brushes 43 are fixed to the middle of the side wall of the fixed cylinder 42; the second cleaning brushes 43 are located below the fermentation tank 17; when the first movable shaft 26 rotates, the first movable shaft 26 will drive the second synchronous belt 4 to rotate, and the rotation of the second synchronous belt 4 will drive the second movable shaft 41 to rotate synchronously, and the rotation of the second movable shaft 41 will drive the fixed cylinder 42 to rotate synchronously. As the fixed cylinder 42 rotates, the second cleaning brush 43 on its surface continuously contacts the outer wall of the fermentation tank 17, causing the second cleaning brush 43 to scrub the outer wall of the fermentation tank 17. This step, through the setting of the second synchronous belt 4, the second movable shaft 41, the fixed cylinder 42, and the second cleaning brush 43, can clean the outer wall of the fermentation tank 17, effectively removing stains, residues, and microorganisms attached to the outer surface of the fermentation tank, so that the outer surface of the fermentation tank 17 is thoroughly cleaned. At the same time, this setting can remove dirt and corrosion from the surface of the tank, reducing corrosion problems caused by long-term exposure to a humid environment.
[0029] like Figure 2 and Figure 3As shown, a gas storage box 5 is installed at the bottom of the cleaning box 1; the gas storage box 5 is located inside the cleaning box 1; an air inlet pipe 51 is fixedly connected to the bottom of the gas storage box 5; multiple air outlets 52 are opened on the top of the gas storage box 5; the air outlets 52 are located below the second cleaning brush 43; the cleaning box 1, the gas storage box 5, the air inlet pipe 51 and the air outlets 52 are all hollow and connected; during operation, the operator connects the blower to the air inlet pipe 51, and then injects hot air into the air inlet pipe 51. At this time, the airflow will pass through the gas storage box 5 and flow into the cleaning box 1 from the air outlets 52. This step of setting up the gas storage box 5, the air inlet pipe 51 and the air outlets 52, by injecting hot air into the cleaning liquid, can accelerate the activity of the chemical components in the cleaning liquid, so that it can more effectively decompose and remove the stains and residues on the surface of the fermentation tank 17, and the high temperature can accelerate the volatilization and decomposition of odors, thereby eliminating the odor on the surface of the fermentation tank 17 and keeping it fresh.
[0030] like Figure 1 and Figure 2 As shown, the second synchronous belt 4 is covered with a waterproof cloth 6; the waterproof cloth 6 is made of elastic material; this step, by setting a waterproof cloth 6 on the outside of the second synchronous belt 4, can reduce the corrosion of the second synchronous belt 4 by the cleaning fluid, and reduce the situation where the transmission performance of the second synchronous belt 4 is reduced or even fails due to liquid corrosion.
[0031] like Figure 1 and Figure 3 As shown, multiple observation windows 7 are provided in the middle of the side wall of the cleaning tank 1; the observation windows 7 are made of transparent material; by setting up the observation windows 7, the staff can directly see the situation inside the cleaning tank 1, promptly identify problems in the cleaning process, such as insufficient cleaning solution, uneven soaking or poor cleaning effect, and make adjustments immediately.
[0032] Working principle: The operator injects cleaning solution into the cleaning tank 1, then uses the fixing component to fix the used fermentation tank 17 between the first upright plate 15 and the second upright plate 16. Next, the electric actuator 13 is activated, which pushes the push plate 14 downwards. At this time, the push plate 14 causes the first upright plate 15, the second upright plate 16, and the fermentation tank 17 to move downwards simultaneously, ensuring that the fermentation tank 17 is completely immersed in the cleaning solution inside the cleaning tank 1. Then, the rotating component is activated, which rotates the fermentation tank 17, allowing it to rotate within the cleaning solution and completely cover all corners of the fermentation tank 17. Simultaneously, the flushing component scrubs the inner wall of the fermentation tank 17 as it rotates, while the cleaning component scrubs... Its outer wall, through the combined action of the rotating component, the flushing component, and the cleaning component, thoroughly cleans every corner of the fermentation tank 17. The worker pulls the first fixing plate 21, placing the fermentation tank 17 between the first fixing plate 21 and the second fixing plate 23. Then, the worker releases the first fixing plate 21, at which point the first fixing plate 21 and the second fixing plate 23 will fix the fermentation tank 17 in place, facilitating its immersion in the cleaning solution and its removal from the solution. When the fermentation tank 17 is completely immersed in the cleaning solution, the worker inserts the first movable shaft 26 into the telescopic rod 2, and then starts the motor 24. The motor 24 drives the first synchronous belt 25 to rotate, which in turn drives the first movable shaft 26 to rotate, causing the first... A movable shaft 26 drives the telescopic rod 2 to rotate, causing the telescopic rod 2 to simultaneously rotate the first fixed plate 21, the fixed rod 22, the second fixed plate 23, and the fermentation tank 17. At this time, the cleaning liquid will completely cover all corners of the fermentation tank 17. The worker inserts the liquid inlet pipe 3 into the fixed rod 22. At this time, one end of the liquid inlet pipe 3 is inside the fermentation tank 17. Because the liquid inlet pipe 3 and the fixed rod 22 are rotatably connected, when the fermentation tank 17 rotates, the liquid inlet pipe 3 and the multiple first cleaning brushes 32 on its side wall will remain relatively stationary in the cleaning liquid, allowing the multiple first cleaning brushes 32 to scrub the inner wall of the rotating fermentation tank 17 from the inside. At the same time, the cleaning liquid is injected into the liquid inlet pipe 3 through the other end of the liquid inlet pipe 3. At this time, the cleaning liquid will flow from multiple... The liquid flows from outlet 31 into the fermentation tank 17, so that the cleaning liquid completely fills the interior of the fermentation tank 17. When the first movable shaft 26 rotates, the first movable shaft 26 will drive the second synchronous belt 4 to rotate. When the second synchronous belt 4 rotates, it will drive the second movable shaft 41 to rotate synchronously. The rotation of the second movable shaft 41 will drive the fixed cylinder 42 fixed in the middle of the second movable shaft 41 to rotate. At this time, when the fixed cylinder 42 rotates, the second cleaning brush 43 on its surface will continuously contact the outer wall of the fermentation tank 17, so that the second cleaning brush 43 scrubs the outer wall of the fermentation tank 17. The operator connects the blower to the air inlet pipe 51 and then injects hot air into the air inlet pipe 51. At this time, the airflow will pass through the air storage box 5 and flow into the cleaning box 1 from the air outlet 52.
