Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, and in particular to an apparatus and method for fermenting and preparing arugula juice. Background Technology

[0002] Aronia berry, scientifically known as *Sorbus nigra*, is rich in anthocyanins, polyphenols, and other active ingredients, possessing strong antioxidant properties and high nutritional value, making it a promising candidate for functional beverages. Microbial fermentation of aronia berry juice not only effectively neutralizes its high acidity and astringency, improving palatability, but also promotes the degradation and transformation of active ingredients, enhancing their absorption rate. Therefore, fermented aronia berry juice products represent the current mainstream direction for the deep processing of aronia berries.

[0003] Currently, most of the equipment used for arugula juice fermentation in industrial production follows the same general fermentation equipment used for grapes, blueberries, and other common fruits and vegetables. This type of equipment is usually a traditional closed or open fermentation tank, mainly composed of a tank body, stirring device, temperature control device, and exhaust structure. The following problems may occur when it is applied to arugula juice fermentation:

[0004] First, the stirring devices in traditional fermentation equipment generally use straight stirring rods or blades, which can only achieve simple radial stirring and cannot turn the raw materials up and down. During the fermentation process, the upper layer of fruit pulp and scum will always float on the surface of the raw materials, which can easily lead to problems such as scum crusting and uneven fermentation in some areas. Second, after fermentation, the insoluble solids originally present in the raw materials and the flocculent precipitates that precipitate during fermentation will together form fruit pulp residue. After pouring out the arugula juice, the fruit pulp residue still needs to be squeezed and filtered, which is a cumbersome process with low production efficiency. Moreover, the juice inside the residue is difficult to be fully squeezed out, which will also reduce the utilization rate of raw materials and the overall juice yield. Summary of the Invention

[0005] The purpose of this invention is to simultaneously solve the problems of the raw materials not being able to be turned over during the fermentation of aronia berry juice, which easily leads to the formation of scum and uneven fermentation in some areas, as well as the inability to fully separate the juice from the pulp residue after fermentation. Therefore, this invention proposes an aronia berry juice fermentation preparation device and preparation method.

[0006] To achieve the above objectives, the present invention employs the following technology: an arugula juice fermentation preparation device, comprising a support frame and a fermentation tank fixed inside the support frame, wherein a pressure relief valve is installed on the top of the fermentation tank, a stirring rod is provided inside the fermentation tank, and a drive assembly is fixedly installed at the bottom of the support frame, and further comprising: A juice processing mechanism includes a connecting rod fixed to the bottom of a stirring rod, a push-pull unit inside the connecting rod, a mounting shell fixed on the stirring rod, an adjustment component inside the mounting shell, a plurality of equally spaced rotating shafts circumferentially connected to the mounting shell, blades fixed to the outer ends of the rotating shafts, and a pressing unit at the bottom of the fermentation tank. When the blades are tilted by the push-pull unit and adjustment assembly, the blades rotate with the stirring rod to agitate the juice; when the blades are horizontal, the pressing unit drives the blades to press the pulp.

[0007] As a further description of the above-mentioned berry juice fermentation preparation device: the push-pull unit includes a threaded rod rotatably connected inside the connecting rod, a slider threadedly connected to the threaded rod is slidably connected inside the connecting rod, and a push-pull rod is fixed to the top of the slider.

[0008] As a further description of the above-mentioned aralia juice fermentation preparation equipment: the adjustment component includes several mounting plates fixed around the top of the push-pull rod. The mounting plates penetrate the outer wall of the stirring rod and are fixed with pairs of protruding rods. A support plate inserted between each pair of protruding rods is fixed on one side of the rotating shaft. The top and bottom walls of the mounting shell are both fixed with blocks.

[0009] As a further description of the above-mentioned berry juice fermentation preparation device: one side edge of each blade is parallel to the axis of rotation fixed thereto.

[0010] As a further description of the above-mentioned berry juice fermentation preparation equipment: the drive assembly includes a transmission unit and a motor fixedly installed on the inner wall of the support. The transmission unit consists of two pulleys connected by belt drive. One pulley is fixed to the motor drive shaft, and the other pulley is rotatably connected to the bottom of the fermentation tank and slidably connected to the connecting rod.

[0011] As a further description of the above-mentioned berry juice fermentation preparation equipment: the pressing unit includes a cylinder fixedly installed at the bottom of the fermentation tank, and the connecting rod is externally rotatably connected to a connecting piece fixed to the telescopic end of the cylinder.

[0012] As a further description of the above-mentioned aralia juice fermentation preparation equipment, it also includes a discharge mechanism, which includes a tray fixed inside the fermentation tank, a connecting pipe fixed to the bottom of the tray, a discharge pipe with a valve fixed to the bottom end of the connecting pipe, and a filter cover fixed to the top of the connecting pipe. The discharge mechanism also includes a flow guiding component and a support structure.

[0013] As a further description of the above-mentioned berry juice fermentation preparation equipment: a discharge port is provided on the inner wall of the tray, and the discharge port is connected to the connecting pipe through a branch pipe. The flow guiding component includes a sealing block slidably connected inside the discharge port. A filter screen is fixed on the outer periphery of the sealing block. An inclined block is fixed on one side of the sealing block, and a spring is provided on the other side.

[0014] As a further description of the above-mentioned berry juice fermentation preparation equipment: the support structure includes a push column fixed to one side of the sealing block, a bent plate fixed to one end of the push column, a support member elastically connected inside the connecting pipe, and a protrusion fixed to the outside of the support member.

[0015] A method for preparing aralia elata juice by fermentation includes the following steps: S1. Pour the aralia elata juice into a fermentation tank and add yeast to ferment; S2. During juice fermentation, the stirring rod and tilted blades are periodically driven by the drive component to rotate and stir the juice. S3. After fermentation is complete, the juice is discharged through the connecting pipe and the discharge pipe, and the pulp residue in the juice is deposited at the bottom of the fermentation tank. S4. The blades are adjusted to a horizontal position by the push-pull unit and the adjustment component, and then the blades are driven to descend by the pressing unit to squeeze the pulp and extract the remaining juice.

[0016] In summary, due to the adoption of the above-mentioned technology in the fermentation preparation equipment and method for aralia elata juice, the beneficial effects of this invention are: 1. When the blades are tilted, the drive assembly drives the blades to rotate, which causes the pulp residue at the bottom of the fermentation tank to turn upwards, pressing the scum on the top of the juice into the juice, promoting uniform fermentation of the juice, and preventing pulp from accumulating on the surface, forming a crust, and growing mold, thus improving the quality of juice fermentation production. Furthermore, after the juice is discharged, the pulp residue remains at the bottom of the fermentation tank. By adjusting the angle of the blades through the push-pull unit and adjustment components, the blades are brought to a horizontal position. Several blades then form a circular pressure plate that matches the size of the bottom end face of the fermentation tank. At this point, the blades are driven downward by the pressing unit, which allows the blades to press the pulp and squeeze out the remaining juice contained in the pulp. Compared to collecting, filtering, and pressing the pulp separately after the juice is discharged, this design not only simplifies the production process and saves manpower, but also ensures that the pulp spread flat at the bottom of the fermentation tank receives uniform pressure from the blades, thereby improving the utilization rate of raw materials and the juice yield. This solves the problem of low utilization rate of pulp mixed with juice after fermentation of arugula juice.

[0017] 2. One edge of the blade is parallel to the axis of rotation fixed to it. Therefore, when the blade is tilted, the bottom edge is horizontal. After adjusting the height of the blade so that the bottom edge of the blade contacts the top surface of the tray, the blade is driven to rotate by the drive component. This allows the blade to scrape the fruit pomace, making it easier to scrape up and remove the compacted fruit pomace, thus accelerating the cleaning efficiency of the fermentation tank. In addition, when there is little residual fruit pomace, scraping the fruit pomace with the blade can also cause the fruit pomace to accumulate. Then, squeezing the fruit pomace with the blade can fully extract the juice and increase the juice yield.

[0018] 3. When compressing the fruit pomace, the installation shell lowers the inclined surface of the extrusion block, pushing the inclined block and sealing block into the discharge port, opening the discharge port and discharging the squeezed juice in time, reducing the amount of juice residue in the fruit pomace, and accelerating the juice fermentation production efficiency. At the same time, the sealing block pushes the protrusion upward through the push column and bending plate, driving the support to support the filter cover, preventing the filter cover from being deformed and damaged by force, and sealing the filter cover so that the fruit pomace will not be squeezed into the filter holes of the filter cover and cause blockage when it is compressed.

[0021] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a fermentation preparation device and method for aralia elata juice according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-12 As shown, the present invention provides an arugula juice fermentation preparation device, including a support 10 and a fermentation tank 11 fixed inside the support 10. The fermentation tank 11 consists of a tank body and a top cover. The top cover is sealed and closed on the tank body, and a pressure relief valve is installed on the top cover to discharge the gas generated during the fermentation process. A stirring rod 13 is provided inside the fermentation tank 11, and a drive assembly 12 for driving the stirring rod 13 to rotate is fixedly installed at the bottom of the support 10.

[0023] When using, open the top cover, pour the pre-treated arugula juice into the tank through the top opening, add yeast and other fermentation materials, and finally close the top cover. Periodically control the drive component 12 to drive the stirring rod 13 to rotate and stir the juice to ensure that the juice ferments evenly.

[0024] Reference Figures 2-8To further improve the uniformity of fermentation and simplify the fermentation process of arugula juice, a juice processing mechanism is provided. The juice processing mechanism includes a connecting rod 21 fixed to the bottom of the stirring rod 13. The drive assembly 12 includes a transmission unit 122 and a motor 121 fixedly installed on the inner wall of the bracket 10. The transmission unit 122 is composed of two pulleys connected by belt drive. One pulley is fixed to the drive shaft of the motor 121, and the other pulley is rotatably connected to the bottom of the fermentation tank 11 and slidably connected to the connecting rod 21. The starter motor 121 drives the pulley fixed to its drive shaft to rotate. This pulley drives another pulley to rotate via a belt, thereby driving the connecting rod 21 and the stirring rod 13 to rotate.

[0025] A mounting shell 23 is fixed on the stirring rod 13. An adjustment component 24 is provided inside the mounting shell 23. A push-pull unit 22 is provided inside the connecting rod 21. Several equidistant rotating shafts 25 are rotatably connected to the mounting shell 23. Blades 26 are fixed to the outer end of the rotating shafts 25. The functional components of aronia berries, such as anthocyanins and polyphenols, are concentrated in the solids such as the peel and pulp. If the pulp residue is completely removed before fermentation, a large amount of functional components will be lost, reducing the nutritional value and functionality of the product. Therefore, the aronia berry juice to be fermented will contain pulp residue. When the blade 26 is tilted, the stirring rod 13 rotates and drives the blade 26 to rotate through the mounting shell 23 and the rotating shaft 25. This not only turns the pulp residue at the bottom of the fermentation tank 11 upward, but also presses the upper scum into the juice, promoting uniform fermentation of the juice. It also prevents the pulp from accumulating on the liquid surface, forming a crust, and growing mold, thus improving the quality of the juice fermentation production.

[0026] Reference Figure 3 The push-pull unit 22 includes a threaded rod 221 rotatably connected inside the connecting rod 21, a slider 222 threadedly connected to the threaded rod 221 inside the connecting rod 21, a push-pull rod 223 fixed to the top of the slider 222, and the top end of the push-pull rod 223 extending into the interior of the stirring rod 13. Reference Figures 5-8 The adjusting assembly 24 includes several mounting plates 241 fixed around the top of the push-pull rod 223. The mounting plates 241 are arranged equidistantly in a circle and correspond one-to-one with each rotating shaft 25. The mounting plates 241 penetrate the outer wall of the stirring rod 13 and are fixed with pairs of protruding rods 242. Each pair of protruding rods 242 are arranged vertically aligned. A support plate 243 is fixed on one side of the rotating shaft 25 and inserted between each pair of protruding rods 242. The top and bottom walls of the mounting shell 23 are both fixed with blocks 244 to limit the deflection angle of the support plate 243. When the blade 26 is tilted, the upper protruding rod 242 of each pair of protruding rods 242 and the block 244 fixed on the bottom wall of the mounting shell 23 clamp the support plate 243, so that the rotating shaft 25 and the blade 26 are locked and the blade 26 will not deflect when it rotates with the stirring rod 13.

[0027] Tightening the threaded rod 221 causes the slider 222 to slide upward inside the connecting rod 21. When the slider 222 drives the push-pull rod 223, the mounting plate 241 and the protruding rod 242 to move upward, the lower protruding rod 242 of each pair of protruding rods 242 pushes the support plate 243 upward until the support plate 243 contacts the stop block 244 fixed to the top wall of the mounting shell 23. During this process, the support plate 243 drives the rotating shaft 25 to rotate, so that the blade 26 changes from an inclined state to a horizontal state. Finally, the support plate 243 is locked again. The bottom of the fermenter 11 is conical, and several blades 26 are horizontally arranged to form a circular pressure plate that matches the size of the bottom end face of the fermenter 11.

[0028] Reference Figure 3 The bottom of the fermentation tank 11 is provided with a pressing unit 27. The pressing unit 27 includes a cylinder 271 fixedly installed at the bottom of the fermentation tank 11. The connecting rod 21 is rotatably connected to a connecting piece 272 fixed to the telescopic end of the cylinder 271. After the juice fermentation is completed and discharged, the pulp residue in the juice remains at the bottom of the fermentation tank 11. At this time, the cylinder 271 is controlled to extend and drive the connecting piece 272 to move down, so that the connecting rod 21, stirring rod 13, mounting shell 23, rotating shaft 25 and blade 26 move down. The blade 26 presses the pulp residue remaining at the bottom of the fermentation tank 11, so that the remaining juice contained in the pulp is squeezed out.

[0029] Compared to collecting, filtering, and pressing the pulp separately after the juice is discharged, this design not only simplifies the fermentation process of aronia berry juice, saves manpower, and speeds up processing efficiency, but also allows the blades 26, which form a circular pressing plate, to apply even pressure to the pulp spread at the bottom of the fermentation tank 11, improving the utilization rate of raw materials and the juice yield, thus solving the problem of pulp mixed with juice and low utilization rate after aronia berry juice fermentation.

[0030] Reference Figure 7 Based on the above design, one side edge of each blade 26 is parallel to the axis of the rotating shaft 25 fixed thereto, so that the bottom edge of the blade 26 is in a horizontal state when it is tilted. After squeezing the fruit residue, the blade 26 is raised and reset and returns to the tilted state. The blade 26 is driven to descend by the pressing unit 27, and then the stirring rod 13 and the blade 26 are driven to rotate by the driving assembly 12. The fruit residue can be scraped by the bottom edge of the blade 26, which makes it easy to scrape up and remove the compacted fruit residue. In addition, when there is little residual fruit residue, scraping the fruit residue with the blade 26 can cause the fruit residue to accumulate and gather. Then, squeezing the fruit residue with the blade 26 can fully extract the juice and increase the juice yield.

[0031] Reference Figures 9-12The fermenter is equipped with a discharge mechanism, which includes a tray 41 fixed inside the fermentation tank 11, a stirring rod 13 passing through the tray 41 and a sealing ring at the connection between the stirring rod 13 and the tray 41, a connecting pipe 42 fixed at the bottom of the tray 41, a discharge pipe 31 with a valve fixed at the bottom end of the connecting pipe 42, and a filter cover 43 fixed at the top of the connecting pipe 42. After the juice fermentation is completed, the valve is opened and the juice can be filtered through the filter cover 43 and discharged directly through the connecting pipe 42 and the discharge pipe 31, which is convenient for subsequent processing. Because of the fruit pulp residue in the juice, the filter cover 43 may become clogged during the juice discharge process. At this time, the bottom edge of the blade 26 can be made to contact the top surface of the support plate 41 by the pressing unit 27, and the stirring rod 13 and the blade 26 can be driven to rotate by the driving component 12, so that the blade 26 can continuously scrape off the fruit pulp accumulated on the filter cover 43 and keep the discharge smooth.

[0032] When the blade 26 is in a horizontal position, the bottom surface of the mounting shell 23 will be lower than the bottom surface of the blade 26. In order to enable the blade 26 to fully compress the fruit residue, a circular groove for accommodating the mounting shell 23 is provided at the center of the top surface of the tray 41. The diameter of the circular groove is 5mm-10mm larger than the diameter of the mounting shell 23.

[0033] Considering that the blade 26 will block the filter cover 43 when squeezing the fruit pulp, causing the squeezed juice to be unable to be discharged in time, and even causing some fruit pulp to be squeezed out through the filter holes of the filter cover 43, a flow guiding component 44 and a support structure 46 are also provided. Reference Figure 10 , Figure 11 and Figure 12 A discharge port is provided on the inner wall of the circular groove of the pallet 41. The discharge port is connected to the connecting pipe 42 through the branch pipe 45. The flow guiding component 44 includes a sealing block 441 slidably connected inside the discharge port. A filter screen 442 is fixed on the outer periphery of the sealing block 441. The filter screen 442 is located between the outer periphery of the sealing block 441 and the inner wall of the discharge port. An inclined block 443 is fixed on one side of the sealing block 441, and a spring 444 is provided on the other side. The inclined block 443 extends out of the discharge port. The spring 444 is always in a compressed state. Under the elastic support of the spring 444, the sealing block 441 abuts against the inner wall of the discharge port, and the sealing block 441 and the inner wall of the discharge port are sealed.

[0034] The stirring rod 13 drives the mounting shell 23, the rotating shaft 25, and the blades 26 to descend. The blades 26 squeeze the fruit pomace, while the bottom of the mounting shell 23 enters the circular groove and squeezes the inclined surface of the inclined block 443, pushing the inclined block 443 and the sealing block 441 into the discharge port. The spring 444 is further compressed. At this time, the sealing block 441 separates from the inner wall of the discharge port and no longer seals the discharge port. After the squeezed juice enters the discharge port, it is filtered by the filter screen 442, then enters the connecting pipe 42 through the branch pipe 45, and is discharged through the discharge pipe 31. This design allows the juice to be discharged in time when the blades 26 squeeze the fruit pomace, reducing the amount of juice residue in the fruit pomace and accelerating the juice fermentation production efficiency.

[0035] During the above process, the fruit residue that was originally in the circular groove will be squeezed by the mounting shell 23, and the squeezed juice will also be discharged through the discharge port, branch pipe 45, tray 41 and discharge pipe 31.

[0036] Reference Figure 11 The support structure 46 includes a pusher 461, one end of which passes through the connecting pipe 42 and the other end extends into the discharge port and is fixed to the sealing block 441. A bent plate 462 is fixed to one end of the pusher 461 and the sealing block 441. A support member 464 is elastically connected to the inside of the connecting pipe 42 by a tension spring. The support member 464 is located directly below the filter cover 43. A protrusion 463 is fixed to the outside of the support member 464. During the juice discharge stage, the valve on the discharge pipe 31 is opened. After passing through the filter cover 43, the juice bypasses the support member 464 and is discharged through the connecting pipe 42 and the discharge pipe 31. During the pomace pressing stage, the mounting shell 23 presses the inclined block 443, which drives the sealing block 441 and the push column 461 to move axially. The push column 461 drives the bending plate 462 to move. The bending plate 462 pushes the protrusion 463 upward through the inclined surface, which drives the support member 464 to move upward to support the filter cover 43 and close the filter cover 43. This prevents the pomace from being squeezed into the filter holes of the filter cover 43 and causing blockage when it is squeezed, and also prevents the filter cover 43 from being deformed and damaged by the force.

[0037] A method for preparing aralia elata juice by fermentation includes the following steps: S1. Pour the aralia elata juice into fermentation tank 11 and add yeast to ferment; S2. During the juice fermentation, the stirring rod 13 and the inclined blade 26 are driven to rotate periodically by the drive component 12 to stir and tumble the juice. S3. After fermentation is complete, the juice is discharged through the connecting pipe 42 and the discharge pipe 31, and the pulp residue in the juice is deposited at the bottom of the fermentation tank 11. S4. The blade 26 is adjusted to a horizontal state by the push-pull unit 22 and the adjustment component 24, and then the blade 26 is driven to descend by the pressing unit 27 to squeeze the pulp and extract the remaining juice.

[0038] Working principle: In the initial state, the fermentation tank 11 contains fermenting arugula juice, and the blades 26 are in an inclined state. The motor 121 is started periodically to drive the pulley fixed to its drive shaft to rotate. This pulley drives another pulley to rotate through the belt, which in turn drives the connecting rod 21 and the stirring rod 13 to rotate. The stirring rod 13 rotates and stirs the juice to promote uniform fermentation of the juice. The rotation of the stirring rod 13 drives the blades 26 to rotate through the mounting shell 23 and the rotating shaft 25. The tilted blades 26 rotate and turn the pulp residue at the bottom of the fermentation tank 11 upward, so that the scum on the top of the juice is pressed into the juice, avoiding the accumulation of pulp on the liquid surface, forming a lid and growing mold. The circulation of the juice inside the fermentation tank 11 can improve the uniformity of fermentation. After fermentation, open the valve on the discharge pipe 31. The juice is filtered through the filter cover 43 and discharged through the connecting pipe 42 and the discharge pipe 31. The pulp residue in the juice will remain at the bottom of the fermentation tank 11. Tightening the threaded rod 221 causes the slider 222 to slide upward inside the connecting rod 21. The slider 222 drives the push-pull rod 223, the mounting plate 241 and the protruding rod 242 to move upward. The lower protruding rod 242 in each pair of protruding rods moves upward and pushes the support plate 243 until the support plate 243 contacts the stop block 244 fixed to the top wall of the mounting shell 23. During this process, the support plate 243 drives the rotating shaft 25 to rotate, so that the blade 26 changes from an inclined state to a horizontal state. The extension of the control cylinder 271 drives the connecting piece 272 to move downward, causing the connecting rod 21, stirring rod 13, mounting shell 23, rotating shaft 25 and blade 26 to move downward. The blade 26 presses the fruit residue retained at the bottom of the fermentation tank 11, squeezing out the remaining juice contained in the fruit residue. During this process, the bottom of the mounting shell 23 enters the circular groove and squeezes the inclined surface of the inclined block 443, pushing the inclined block 443 and sealing block 441 into the discharge port, opening the discharge port. The squeezed juice enters the discharge port, is filtered by the filter screen 442, then enters the connecting pipe 42 through the branch pipe 45, and finally is discharged through the discharge pipe 31. While the housing 23 is pressing the inclined block 443, it drives the sealing block 441 and the push column 461 to move axially. The push column 461 drives the bending plate 462 to move. The bending plate 462 pushes the protrusion 463 upward through the inclined surface, which drives the support 464 to move upward to support the filter cover 43 and close the filter cover 43. This prevents the fruit pulp from being squeezed into the filter holes of the filter cover 43 and causing blockage, and avoids the filter cover 43 from being deformed and damaged by force. When the housing 23 moves upward and resets, the sealing block 441 is reset under the elastic force of the spring 444, the support 464 is reset by the tension spring, and the filter cover 43 returns to the open state.
