Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and particularly to a drum-type infiltration fermentation device for coffee bean processing. Background Art

[0002] The drum-type infiltration fermentation device is a device specifically used for the fermentation treatment of coffee beans. By simulating the fermentation process of coffee beans in the natural environment, using the rotation of the drum and specific environmental conditions, the coffee beans are evenly infiltrated and fermented, thereby improving the flavor and quality of the coffee beans. Further, in the coffee bean processing process, the infiltration fermentation link plays a crucial role in the final flavor and quality of the coffee beans. The currently widely used drum-type infiltration fermentation devices on the market have exposed a series of key problems that need to be solved urgently during actual operation. The spray system of the existing drum-type infiltration fermentation device has obvious defects. Most of the spray heads are fixed in specific positions, and the spray angle and coverage are very limited. This causes a huge difference in the amount of infiltration liquid received by the coffee beans in different parts of the drum. Some coffee beans may have deteriorated flavor due to excessive infiltration, while some are under-infiltrated, seriously affecting the infiltration uniformity. This uneven infiltration directly leads to inconsistent fermentation degrees of the coffee beans, and ultimately makes it difficult to maintain stability and unity in the taste and flavor of the finished coffee, unable to meet the increasingly stringent requirements of consumers for high-quality coffee, and greatly reducing the market competitiveness of coffee products.

[0003] In addition, during the fermentation process, coffee beans will produce viscous substances, and these mucus are extremely easy to adhere to the inner wall of the drum. As time goes by, the mucus accumulates continuously, not only interfering with the subsequent fermentation process, hindering the uniform transfer of heat and gas, but also creating a breeding ground for microorganisms, further threatening the quality of the coffee beans. The traditional device lacks an effective inner wall cleaning mechanism. Once it is necessary to clean the inner wall of the drum, the operator can only rely on manual operation, which not only consumes a large amount of manpower, material resources and time, greatly increasing the production cost, but also it is difficult to completely remove the stubbornly adhering mucus manually, and it is difficult to ensure the cleanliness of the equipment, leaving a quality hidden danger for the subsequent fermentation.

[0004] Therefore, the present invention proposes a drum-type infiltration fermentation device for coffee bean processing to solve the above problems. Summary of the Invention

[0009] Preferably, the auxiliary turning and scraping mechanism includes a spray inner cavity, the spray inner cavity is opened in the spray head, a cross-shaped bracket is fixedly connected to the top of the spray inner cavity, a return spring is fixedly connected to the middle of the side of the cross-shaped bracket away from the L-shaped rotating rod, a piston piece is fixedly connected to the end of the return spring away from the cross-shaped bracket, a turning ring is fixedly connected to the outer ring of the spray head, plug-in columns are fixedly connected to the middle of the outer rings on both sides of the turning ring, sleeves are slidably sleeved on the outer rings of the ends of the plug-in columns away from the turning ring, an auxiliary spring is fixedly connected between the plug-in columns and the sleeves, and a silica gel strip is fixedly connected to the end of the sleeve away from the plug-in column.

[0010] Preferably, the inner cavity of the auxiliary cavity is communicated with the drum machine, the first motor is electrically connected to an external controller, the communicating pipe is communicated with the spray inner cavity through the control sphere, and the spray head is composed of a cylindrical pipe and an expansion block.

[0011] Preferably, the second motor is electrically connected to an external controller, and one end of the connecting pipe away from the control sphere is connected to an infiltration liquid storage device.

[0013] Compared with the prior art, the present invention provides a drum-type infiltration fermentation device for coffee bean processing, having the following beneficial effects: 1. Through the setting of the infiltration range guiding mechanism, with the forward and reverse settings of the first motor and the second motor, the spray head is promoted to rotate in multiple angles in the horizontal and vertical directions, breaking through the limitation of the fixed angle of the traditional spray head, and spraying the infiltration liquid in all directions and without dead angles to each area in the drum, avoiding the situation that some coffee beans are over-infiltrated and some are under-infiltrated. Each coffee bean can start the fermentation process in a uniform infiltration environment, laying a solid foundation for the consistency of subsequent fermentation, greatly improving the uniformity of coffee bean infiltration, reducing the quality difference of coffee beans caused by uneven infiltration, reducing the defective rate, improving the utilization rate of raw materials, reducing the raw material cost. Further, the spray head rotating in multiple angles can flexibly adjust the spraying angle and range according to the characteristics of different batches of coffee beans, such as particle size, density distribution and different fermentation process requirements, realizing personalized infiltration, and enhancing the adaptability and flexibility of the equipment to diverse production needs.

[0014] 2. Through the setting of the auxiliary turning and scraping wall mechanism, the turning ring turns the material as the spray head rotates, which can break the original accumulation state of the coffee beans, so that the coffee beans originally at the bottom or inside and difficult to contact the infiltration liquid are continuously turned to the upper layer and fully exposed to the infiltration liquid sprayed in multiple angles. The coffee beans that originally received insufficient infiltration liquid due to position limitation can be sufficiently infiltrated, further improving the comprehensiveness and uniformity of infiltration, making the amount of infiltration liquid absorbed by each coffee bean closer, providing more consistent basic conditions for subsequent fermentation. The turning action makes the contact and mixing between coffee beans more sufficient, which helps the uniform distribution of microorganisms in the coffee bean group. At the same time, this sufficient mixing can make the heat transfer evenly between coffee beans, avoiding local overheating or overcooling, maintaining a stable fermentation environment, and ensuring the smooth progress of the fermentation process.

[0015] 3. Through the setting of the silicone strips, during the process of the turnover ring driving the material to turn over, the silicone strips on both sides can scrape the inner wall of the drum machine in real time. The mucus produced by fermentation has strong viscosity. If it is not cleaned in time, it will accumulate continuously, affecting the normal operation of the equipment. When the silicone strips rotate with the turnover ring, they can continuously clean the inner wall, scrape off the mucus, prevent it from drying on the wall surface, greatly improve the cleaning efficiency of the inner wall, effectively maintain the cleanliness inside the equipment, avoid mucus interfering with the subsequent fermentation process, and the accumulation of mucus on the inner wall will change the heat conduction and gas flow conditions inside the drum machine. Cleaning the mucus in time can ensure the uniform transfer of heat in the drum, making the fermentation temperature of each part of the coffee beans consistent. At the same time, it prevents the gas flow from being blocked due to the mucus blocking the ventilation channels, maintains a good fermentation environment, ensures the smooth progress of the fermentation process, and improves the stability of the coffee bean fermentation quality. The setting of the auxiliary spring between the insertion column and the sleeve can be flexibly adjusted according to the actual situation of the inner wall of the drum machine, so that the silicone strips always fit the inner wall and effectively carry out the scraping work.

[0016] 4. Through the combined use of the cross bracket, the return spring, and the piston piece, when the infiltration liquid in the connecting pipe flows into the spray cavity, under the action of the water flow, the piston piece is pushed downward. Due to the shape of the spray head, the space on both sides provides a flow channel for the infiltration liquid. The infiltration liquid flows through the space on both sides of the piston piece to the spraying area at the bottom of the spray head, avoiding excessive pressure caused by the direct impact of the water flow, preventing the infiltration liquid from splashing or flowing back at the inlet, enabling the infiltration liquid to flow smoothly and evenly into the drum machine, ensuring the smooth progress of the coffee bean infiltration process, being beneficial to improving the uniformity and effect of infiltration. Further, the air pressure generated by fermentation pushes the piston piece to rise reversely, expanding the internal space to accommodate gas, effectively regulating the air pressure in the drum, preventing equipment damage or interference with the fermentation process due to excessive air pressure, ensuring the stability of the fermentation environment, and being beneficial to the normal progress of the fermentation process.

[0022] A further embodiment: Please refer to Figures 6 to 8 as shown in: The auxiliary flipping and wall scraping mechanism 3 is used to synchronously rotate during multi-angle spraying to flip the sprayed coffee bean material and scrape the inner wall of the fermentation mucus. The auxiliary flipping and wall scraping mechanism 3 includes a spraying inner cavity 31, which is opened in the spray head 26. A cross bracket 32 is fixedly connected to the top of the spraying inner cavity 31. The cross bracket 32 is mainly used to assist the piston piece 34 to slide by the general return spring 33. A return spring 33 is fixedly connected to the middle of the side of the cross bracket 32 away from the L-shaped rotating rod 24. One end of the return spring 33 away from the cross bracket 32 is fixedly connected to the piston piece 34. The piston piece 34 is slidably connected in the spraying inner cavity 31. The cross bracket 32, the return spring 33, and the piston piece 34 are all arranged in the cylindrical tube of the spray head 26. A flipping ring 35 is fixedly connected to the outer circle of the spray head 26. Plug-in columns 36 are fixedly connected to the middle outer circles on both sides of the flipping ring 35. The outer circle of one end of the plug-in column 36 away from the flipping ring 35 is slidably sleeved with a sleeve 37. An auxiliary spring 38 is fixedly connected between the plug-in column 36 and the sleeve 37. One end of the sleeve 37 away from the plug-in column 36 is fixedly connected to a silica gel strip 39. The silica gel strip 39 is mainly used to scrape the inner wall of the drum machine 1. The silica gel strip 39 is made of silica gel material.

[0023] The working principle of all the contents in the above embodiments is as follows: In the initial state: The first motor 23 and the second motor 28 are not started. The return spring 33 is not compressed or stretched. The piston piece 34 is in the cylindrical tube of the spray head 26. The drum machine 1 is filled with unsoaked coffee bean material, and the spray head 26 does not spray the soaking liquid.

[0024] The following is the working process of the wetting range guiding mechanism 2 for adjusting the wetting liquid sprayed on the coffee beans by rotating at multiple angles in the axial and vertical directions: During use, the first motor 23 is started and energized under the control of an external controller. The output shaft of the first motor 23 rotates, thereby driving the L-shaped rotating rod 24 fixedly connected to the output shaft of the first motor 23 to rotate forward by 180 degrees in the horizontal position and then rotate backward by 180 degrees. While one end of the L-shaped rotating rod 24 swings with the rotation of the first motor 23, since the L-shaped rotating rod 24 is rotatably connected to the control sphere 25, the control sphere 25 and the spray head 26 are synchronously driven to swing in the horizontal position with the L-shaped rotating rod 24 as the axis. Further, while the first motor 23 starts to rotate forward and backward, the second motor 28 is started synchronously, driving the L-shaped deflecting body 29 to rotate forward and backward in the vertical position. Since one end of the L-shaped deflecting body 29 away from the second motor 28 is rotatably connected to a slide rod 210, and the slide rod 210 is slidably connected to an arc-shaped groove 27 formed in the outer circle of the control sphere 25, when the L-shaped deflecting body 29 rotates forward and backward in the vertical position, the slide rod 210 drives the control sphere 25 to rotate forward and backward in the vertical position under the swing of the L-shaped deflecting body 29 and the restriction of the arc-shaped groove 27 and the slide rod 210. This rotation is transmitted to the spray head 26 through the control sphere 25, thereby driving the spray head 26 to rotate forward and backward vertically and horizontally. At this time, the connecting pipe 211 introduces the infiltration liquid into the spray head 26 through the control sphere 25 for spraying. During the process of the spray head 26 spraying the infiltration liquid, with the multi-directional rotation effect, the infiltration liquid is better sprayed onto the coffee bean material for uniform infiltration; Through the setting of the infiltration range guiding mechanism 2, under the forward and reverse settings of the first motor 23 and the second motor 28, the spray head 26 is promoted to rotate forward and backward at multiple angles horizontally and vertically, breaking through the limitation of the fixed angle of the traditional nozzle, spraying the infiltration liquid in all directions and without dead angles to each area inside the drum, avoiding the situation of over-infiltration of some coffee beans and insufficient infiltration of some, enabling each coffee bean to start the fermentation process in a uniform infiltration environment, laying a solid foundation for the consistency of subsequent fermentation, greatly improving the uniformity of coffee bean infiltration, reducing the quality difference of coffee beans caused by uneven infiltration, reducing the defective rate, improving the utilization rate of raw materials, reducing the raw material cost. Further, the spray head 26 rotating at multiple angles can flexibly adjust the spraying angle and range according to the characteristics of different batches of coffee beans, such as particle size, density distribution, and different fermentation process requirements, realizing personalized infiltration, and enhancing the adaptability and flexibility of the equipment to diverse production needs.

[0025] Please refer to the above working process Figures 1 to 5 。

[0026] The following is the working process of the auxiliary flipping and scraping mechanism 3 for synchronously rotating and flipping the coffee bean material being sprayed and scraping the fermentation mucus on the inner wall during multi-angle spraying: When in use, with the action of the infiltration range guide mechanism 2, the control ball 25 is driven by the first motor 23 and the second motor 28 to rotate at multiple angles, and then transmitted to the spray head 26 for rotating at multiple angles. Since the flip ring 35 is fixedly connected to the outer ring of the spray head 26, when the spray head 26 rotates vertically and horizontally with the control ball 25, the flip ring 35 is synchronously deflected by the rotation movement of the spray head 26. Therefore, when the spray head 26 sprays the infiltration liquid, the flip ring 35 stirs and flips the internal coffee bean material in multiple directions to avoid the accumulation of coffee bean material and the problem of uneven infiltration, thereby achieving In the next step, when the flip ring 35 flips the material with the rotation of the spray head 26, the two sides of the flip ring 35 are connected with silicone strips 39 through the cooperation of the plug-in column 36, the sleeve 37 and the auxiliary spring 38. Under the rotation movement of the flip ring 35, the silicone strip 39 rotates synchronously with the flipping movement of the flip ring 35. During this rotation process, since the silicone strip 39 is in contact with the inner wall of the drum machine 1, the inner wall is scraped during the deflection process. In addition, under the elastic action of the auxiliary spring 38 between the plug-in column 36 and the sleeve 37, there is a certain contraction space to prevent the silicone strip 39 from causing damage to the inner wall of the drum machine 1 during the scraping process. Furthermore, when the infiltration liquid in the connecting pipe 211 flows into the spray head 26, the impact of the liquid pushes the piston plate 34 in the spray head 26 to slide downward, and then the return spring 33 is stretched. The piston plate 34 is at the lower end of the spray head 26, and the liquid flows to the lower end of the spray head 26 through the edge of the piston plate 34, and then is sprayed into the drum machine 1. During the infiltration and fermentation of the coffee bean material in the drum machine 1, the fermentation will produce gas, which will increase the air pressure in the drum machine 1. Therefore, when the air pressure in the drum machine 1 increases, the air pressure resists the piston plate 34, and then pushes the piston plate 34 to move upward, and the return spring 33 is compressed, thereby reducing the space between the piston plate 34 and the cross bracket 32, accommodating the gas produced by the fermentation, and avoiding excessive air pressure on the inner wall to damage the drum machine 1.

[0027] By setting the auxiliary flipping scraping mechanism 3, the flipping ring 35 flips the material with the rotation of the spray head 26, which can break the original accumulation state of the coffee beans, so that the coffee beans that were originally at the bottom or inside and difficult to contact the infiltration liquid are constantly flipped to the upper layer and fully exposed to the infiltration liquid sprayed by multi-angle rotation. The coffee beans that originally received insufficient infiltration liquid due to position limitations can be fully infiltrated, further improving the comprehensiveness and uniformity of the infiltration, so that each coffee bean absorbs a closer amount of infiltration liquid, providing more consistent basic conditions for subsequent fermentation. The flipping action makes the contact and mixing between coffee beans more sufficient, which helps to evenly distribute microorganisms in the coffee bean group. At the same time, this sufficient mixing can evenly transfer heat between coffee beans, avoid local overheating or overcooling, maintain a stable fermentation environment, and ensure the smooth progress of the fermentation process.

[0028] With the setting of the silica gel strip 39, during the process of the flipping ring 35 flipping to drive the material to flip, the silica gel strips 39 on both sides can scrape the inner wall of the drum machine 1 in real time. The mucus produced by fermentation has strong viscosity. If it is not cleaned in time, it will accumulate continuously, affecting the normal operation of the equipment. When the silica gel strip 39 rotates with the flipping ring 35, it can continuously clean the inner wall, scrape off the mucus, prevent it from drying on the wall surface, greatly improve the inner wall cleaning efficiency, effectively maintain the cleanliness inside the equipment, avoid mucus interfering with the subsequent fermentation process, and the accumulation of mucus on the inner wall will change the heat conduction and gas flow conditions inside the drum machine 1. Cleaning the mucus in time can ensure uniform heat transfer in the drum, make the fermentation temperature of each part of the coffee beans consistent. At the same time, it prevents the gas flow from being blocked due to the mucus blocking the ventilation holes, maintains a good fermentation environment, ensures the smooth progress of the fermentation process, and improves the stability of the coffee bean fermentation quality. The setting of the auxiliary spring 38 between the plug post 36 and the sleeve 37 can be flexibly adjusted according to the actual situation of the inner wall of the drum machine 1, so that the silica gel strip 39 always fits the inner wall and effectively performs the scraping work.

[0029] Through the coordinated use of the cross bracket 32, the return spring 33, and the piston piece 34, when the infiltration liquid in the communication pipe 211 flows into the spray cavity 31, under the action of the water flow, the piston piece 34 is pushed downward. Due to the shape of the spray head 26, the space on both sides provides a flow channel for the infiltration liquid. The infiltration liquid flows through the space on both sides of the piston piece 34 to the spraying area at the bottom of the spray head 26, avoiding excessive pressure caused by the direct impact of the water flow, preventing the infiltration liquid from splashing or flowing back at the inlet, enabling the infiltration liquid to flow smoothly and evenly into the drum machine 1, ensuring the smooth progress of the coffee bean infiltration process, and being beneficial to improving the uniformity and effect of infiltration. Further, the air pressure generated by fermentation pushes the piston piece 34 to rise reversely, expanding the internal space to accommodate gas, effectively regulating the air pressure in the drum, preventing equipment damage or fermentation process interference caused by excessive air pressure, ensuring the stability of the fermentation environment, and being beneficial to the normal progress of the fermentation process.
