Description

Technical Field

[0001] The present invention relates to the technical field of agricultural processing, in particular to a micro-fermentation processing system. Background Art

[0002] Coffee is a popular beverage worldwide, with consumption increasing year by year. However, lesser-known is the fact that coffee cherries, a byproduct of coffee bean production, have long been treated as waste. With growing environmental awareness and emphasis on efficient resource utilization, people are increasingly recognizing the enormous potential of coffee cherries. In fact, coffee cherries are rich in various beneficial compounds, such as antioxidants, dietary fiber, and chlorogenic acid, offering the potential for their transformation into products with health benefits.

[0003] Traditional coffee cascara processing methods primarily focus on a simple drying and roasting process, used to create a new beverage called "coffee cascara tea." While this method is simple and easy to implement, the fermentation stage typically relies on natural fermentation. Natural fermentation refers to the process of fermenting by utilizing the microbial communities present in the environment without the addition of any specific microbial strains. While this method can impart a unique flavor to the product, it has numerous limitations due to a lack of effective control over fermentation conditions.

[0004] First, natural fermentation is relatively slow, meaning it takes longer to complete, increasing production costs. Second, environmental factors such as temperature and humidity fluctuations, as well as unpredictable microbial composition, lead to poor fermentation stability. These unstable factors can easily cause the coffee cherries to mold or spoil during fermentation, seriously affecting the quality and safety of the final product. Furthermore, consistent quality between batches is difficult to achieve, posing an obstacle to large-scale production and market expansion. Summary of the Invention

[0005] The purpose of the present invention is to provide a micro-fermentation processing system for mechanized fermentation processing of coffee peels, which can effectively improve the overall efficiency, effectively prevent them from becoming moldy and corrupt, and improve the quality of the product.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a micro-fermentation processing system, comprising a fermentation room, a fermentation inlet is provided at the upper end of the fermentation room, a plurality of fermentation conveyors distributed from top to bottom are arranged in the fermentation room, and two adjacent fermentation conveyors are staggered and arranged at the end to receive materials dropped from above, a fermentation discharge port is provided at the tail end of the lowest fermentation conveyor in the fermentation room, an ultraviolet disinfection lamp is provided at the top of the fermentation room, a first hot air blower is installed at the upper end of the fermentation room, the outlet end of the first hot air blower is connected to the interior of the fermentation room, and a first dehumidification port is provided on the side wall of the fermentation room; It also includes a drying room located on one side of the fermentation discharge port, a drying inlet is provided at the upper end of the drying room, a first elevator is connected between the fermentation discharge port and the drying inlet, a plurality of drying conveyors distributed from top to bottom are provided in the drying room, and the two adjacent drying conveyors on each upper side are staggered and arranged at the end to receive materials falling from above, a drying discharge port is provided at the tail end of the lowest drying conveyor in the drying room, a second hot air blower is installed at the upper end of the drying room, the outlet end of the second hot air blower is communicated with the interior of the drying room, and a second dehumidification port is provided on the side wall of the drying room; It also includes a vibrating screening machine located on one side of the drying discharge port, and a second elevator is connected between the drying discharge port and the upper side of one end of the vibrating screening machine; The invention also includes a tunnel aroma machine, which includes a strip-shaped tunnel cover and an aroma conveyor located in the strip-shaped tunnel cover, wherein both ends of the aroma conveyor extend out of the two ends of the strip-shaped tunnel cover, and a plurality of electric heating tubes are transversely arranged in the strip-shaped tunnel cover and distributed along the length thereof; It also includes a cooling conveyor located at the tail end of the Titian conveyor.

[0007] By adopting the above technical solution, its working principle is as follows: 1. Micro-fermentation: The prepared coffee peels are added to the fermentation feed port through an elevator and eventually fall onto the fermentation conveyor above. In the fermentation room, the first hot air blower generates hot air to maintain the optimal constant temperature for fermentation in the fermentation room. The coffee peels are conveyed to the other end on the fermentation conveyor. During the process, the ultraviolet disinfection lamp sterilizes the surface of the coffee peels with ultraviolet light to kill the mold on the surface and prevent mildew and corruption. The peels then continue to slowly snake through each fermentation conveyor to complete micro-fermentation at a suitable temperature. 2. Dehydration and drying: The peels after micro-fermentation are discharged from the fermentation outlet to the first elevator. The first elevator transports the material through the drying inlet and falls onto the drying conveyor. The second hot air blower generates hot air to generate a higher temperature in the drying box to dehydrate and dry the peels. The hot air takes away the moisture of the material and terminates the micro-fermentation. Finally, the dehydrated and dried peels are discharged from the drying outlet. 3. Vibration classification: the peels discharged from the drying outlet are transported to the top of the vibration screening machine through the second elevator. The peels are vibrated on the vibration screening machine, so that the peels gradually fall onto the screens of different layers according to their volume, and some small particles fall into the bottom layer of the vibration screening machine. Finally, the peels that have completed classification are discharged from the other end. 4. Baking and aroma enhancement: add the peels evenly to the aroma enhancement conveyor of the tunnel aroma enhancement machine, and slowly pass through the electric heating tube in the strip tunnel cover. The electric heating tube generates high temperature to bake and enhance the aroma of the material; 5. Cooling: The cascara tea coming out of the tail end of the aroma conveyor falls onto the cooling conveyor and is slowly conveyed thereon, so that the cascara tea is gradually cooled on the aroma conveyor, and finally the cooled cascara tea is stored and packaged.

[0032] It also includes a tunnel aroma machine 7, which includes a strip tunnel cover 71 and a aroma conveyor 72 located in the strip tunnel cover 71. Both ends of the aroma conveyor 72 extend out of the two ends of the strip tunnel cover 71.

The electric heating tubes 73 generate high temperature to bake and aromatize the material. A plurality of horizontal connecting bars 74 are arranged transversely in the strip tunnel cover 71, and a plurality of vertical connecting bars 75 are arranged downwardly on each horizontal connecting bar 74. The lower end of each vertical connecting bar 75 is connected to a pointed shovel 76. The front end of each pointed shovel 76 is pointed and faces the entrance end of the strip tunnel cover 71. Both sides of each pointed shovel 76 gradually expand outward and gradually rise backward. The two sides of the pointed shovel 76 are outward-turned arc surfaces. The pointed shovels 76 on each adjacent two levels are staggered. After the material passes through the tip of the pointed shovel 76, it is gradually pulled and turned over by the arc surface of the pointed shovel 76 during the transportation process of the Titian conveyor 72, so as to achieve the effect of continuous turning over.

[0033] It also includes a cooling conveyor 8 located at the tail end of the Titian conveyor 72. The cooling conveyor 8 is provided with an air pipe 81 along its length. The air pipe 81 is connected to a plurality of jet strips 82 located above the cooling conveyor 8 and distributed along its length. The lower end of each jet strip 82 is provided with an air jet port. An air pump 83 is provided outside the cooling conveyor 8. The outlet end of the air pump 83 is connected to the air pipe 81 through an air guide pipe 84. When the air pump 83 is working, the jet port of the jet strip 82 can spray cold air downward, thereby realizing rapid cooling of the material.

[0034] Working principle: 1. Micro-fermentation: The prepared coffee peels are added to the feeding hopper 22 through the elevator, and fall onto the diffusion conveyor 21 and are transported forward. After passing through the guide bar 24, they are gradually dispersed outward and evenly distributed on the diffusion conveyor 21. Finally, they are diffused and fall from the fermentation inlet 11 to the fermentation conveyor 12 above. In the fermentation room 1, the first hot air blower 14 generates hot air to maintain the optimal constant temperature for fermentation in the fermentation room 1. The coffee peels are transported to the other end on the fermentation conveyor 12. During the process, the ultraviolet disinfection lamp 16 performs ultraviolet sterilization on the surface of the coffee peels. The flipping drive motor 36 drives the hollow negative pressure roller 3 to rotate synchronously with the fermentation conveyor 12. When the peels are close to the hollow negative pressure roller 3 Afterwards, due to the operation of the negative pressure pump 38, the negative pressure hole 31 generates negative pressure, which will adsorb the peel on the surface of the hollow negative pressure roller 3 and rotate forward with it until it passes through the C-shaped guide groove 34. At the upper part of the C-shaped guide groove 34, it is further adsorbed by the suction hole 35. The side of the peel in contact with the hollow negative pressure roller 3 is guided downward by the C-shaped guide groove 34. When it is pushed to the lower part of the C-shaped guide groove 34 and is blocked without suction, the material gradually slides out from the lower side of the C-shaped guide groove 34 to realize the material turning over, so that the other side of the peel can also be irradiated with ultraviolet rays, which fully kills the mold on its surface and prevents mildew and corruption. Subsequently, the peel continues to pass through each fermentation conveyor 12 in a slow snake shape and completes micro-fermentation at a suitable temperature. 2. Dehydration and drying: The peels after micro-fermentation are discharged from the fermentation outlet 13 to the first elevator 51. The first elevator 51 transports the material through the drying inlet 41 and falls onto the drying conveyor 42. The second hot air blower 44 generates hot air to generate a higher temperature in the drying box to dehydrate and dry the peels. The hot air removes the moisture from the material and terminates the micro-fermentation. Finally, the dehydrated and dried peels are discharged from the drying outlet 43. 3. Vibration classification: the peels discharged from the drying outlet 43 are transported to the top of the vibrating screen 6 through the second elevator 53. The peels are vibrated on the vibrating screen 6, causing the peels to gradually fall onto the screens 66 of different layers according to their volume, and some small granular impurities fall to the bottom layer of the vibrating screen 6. Finally, the peels that have completed classification are discharged from the other end. 4. Baking and aroma enhancement: the peels are evenly added to the aroma enhancement conveyor 72 of the tunnel aroma enhancement machine 7, and slowly passed through the electric heating tube 73 in the strip tunnel cover 71. The electric heating tube 73 generates high temperature to bake and aroma enhance the material. During the process, after the peels pass through the tip of the pointed shovel 76, they are gradually pulled and turned by the arc surface of the pointed shovel 76 during the conveyance of the aroma enhancement conveyor 72, so as to achieve the effect of continuous turning over and even baking and aroma enhancement; 5. Cooling: The cascara tea coming out of the tail end of the aroma conveyor 72 falls onto the cooling conveyor 8 and is slowly conveyed along with it. During this process, the air pump 83 works to enable the air jets of the air jet strips 82 to spray cold air downward, thereby quickly cooling the cascara tea that passes through. Finally, the cooled cascara tea is stored and packaged.
