Description

Technical Field

[0001] The invention relates to the technical field of ginsenoside processing, in particular to a ginsenoside fermentation device. Background Art

[0002] Ginsenosides are an important class of active ingredients in ginseng, with multiple biological activities, such as anti-tumor, antioxidant, and immunomodulatory. Traditionally, ginsenosides are mainly obtained by extracting ginseng roots, but this method has problems of resource limitations and high costs. In order to increase the yield of ginsenosides and reduce costs, a method of producing ginsenosides using microbial fermentation technology has emerged. Ginsenoside fermentation generally uses ginseng roots as fermentation raw materials, but during the fermentation process, the raw materials will gradually settle to the bottom of the fermentation tank under the action of gravity, so a stirring mechanism is set in the fermentation tank to implement stirring and mixing.

[0003] However, the existing stirring mechanism generally only rotates horizontally. Although it can mix the raw materials to a certain extent, the ginseng roots will still settle, resulting in uneven distribution of the raw materials in the upper and lower layers of the fermentation tank, affecting the fermentation effect of the raw materials; secondly, during the stirring process of the stirring mechanism, the end of the stirring rod away from the rotating shaft is in a suspended state, and the upper end of the stirring mechanism is in conflict with the top of the fermentation tank, and the lower end is in conflict with the bottom wall of the fermentation tank, or only the lower end is connected to the bottom of the fermentation tank. Therefore, during the stirring operation, the stirring mechanism is prone to insufficient stability both as a whole and as the stirring rod, which is easy to affect the stirring effect and the service life of the stirring mechanism as a whole; furthermore, when the upper end of the stirring mechanism is in conflict with the top of the fermentation tank and the lower end is in conflict with the bottom wall of the fermentation tank, although the stirring mechanism as a whole can be disassembled from the fermentation tank, the above-mentioned stirring problem still exists. When only the lower end of the stirring mechanism is connected to the bottom of the fermentation tank, the stirring mechanism as a whole cannot be disassembled, which is not conducive to the cleaning operation of the stirring mechanism and the fermentation tank body, affecting the subsequent fermentation operation.

[0032] See also Figure 2 , Figure 3 and Figure 4 The stirring mechanism 3 includes a central shaft 31 which is rotatably mounted in the middle of the tank cover 2 and passes through the tank cover 2 from top to bottom. A movable sleeve 32 located below the tank cover 2 is slidably mounted on the outer side of the central shaft 31. Several groups of stirring rods 33 are evenly distributed on the outer side of the movable sleeve 32. Several stirring rods 33 in the same group are evenly mounted on the outer side of the movable sleeve 32 in the circumferential direction. Two supporting plates 34 symmetrically about the axis of the stirring rod 33 are rotatably connected on the outer side of the stirring rod 33. An angle adjustment assembly 35 driving the two supporting plates 34 to rotate is installed at the bottom of the stirring rod 33. A stirring rod 2 36 located below the movable sleeve 32 is evenly connected on the outer side of the central shaft 31 in the circumferential direction. It should be noted that the movable sleeve 32 is assembled from a plurality of arc plates of the same size and formed by welding (the welding seam is not shown in the figure) to facilitate the installation of its inner parts.

[0033] See also Figure 1 and Figure 6 The driving mechanism 4 includes a support frame 41 fixedly mounted on the top of the tank cover 2, a driving motor 42 fixedly mounted on the top of the support frame 41, the bottom end of the output shaft of the driving motor 42 passes through the inner side of the support frame 41 and is fixedly connected to the top of the central shaft 31, a slip ring 43 is rotatably connected to the top of the movable sleeve 32, and an up and down moving component 44 is installed on the support frame 41 to drive the slip ring 43 to move up and down.

[0034] See also Figure 2 , Figure 4 and Figure 5The angle adjustment assembly 35 includes a slide groove 351 opened at the bottom of the stirring rod 33, a threaded rod 352 is rotatably installed inside the slide groove 351, a trapezoidal push block 353 is slidably installed at the bottom of the stirring rod 33 along its axial direction, the top of the trapezoidal push block 353 is threadedly connected to the threaded rod 352, the lower end of the trapezoidal push block 353 is an isosceles trapezoid and the hypotenuse is away from the movable sleeve 32, and the bottom of the rotating end of the support plate 34 is fixedly connected with a push rod matching the hypotenuse of the trapezoidal push block 353 354, one end of the threaded rod 352 close to the center of the central shaft 31 rotates through the inner side of the movable sleeve 32 and is fixedly connected with a gear 355. A plurality of racks 356 are evenly installed on the inner circumference of the central shaft 31. The gears 355 are meshed with the corresponding racks 356. Except for the lowest trapezoidal push block 353, the bottoms of the other trapezoidal push blocks 353 are fixedly connected with a reinforcing rod 357. The bottom end of the reinforcing rod 357 slides against the top of the stirring rod 33 below it.

[0035] See also Figure 1-Figure 6 When the movable sleeve 32 moves upward along the central axis 31, the rack 356 is used to drive the gear 355 and the threaded rod 352 to rotate, and then the threaded rod 352 drives the trapezoidal push block 353 to move away from the movable sleeve 32, and the inclined edges on both sides of the trapezoidal push block 353 are used to push the push rod 354 and the support plate 34 to rotate upward, so that the support plates 34 on both sides of the stirring rod 33 are converted into a V shape, and the support plates 34 are used to transport the raw materials on the lower layer upward, so that the raw materials on the upper and lower layers are fully mixed, thereby improving the uniformity of raw material fermentation.

[0036] When the trapezoidal push block 353 drives the reinforcing rod 357 to move away from the movable sleeve 32, the reinforcing rod 357 can provide support between two adjacent stirring rods 33, strengthen the support strength between the two adjacent stirring rods 33, prevent the stirring rod 33 from deforming, and help improve the stirring and mixing effect.

[0037] When the movable sleeve 32 moves downward along the central axis 31, the rack 356 drives the gear 355 and the threaded rod 352 to rotate in the opposite direction, and then the threaded rod 352 drives the trapezoidal push block 353 to move toward the movable sleeve 32, so that the hypotenuses on both sides of the trapezoidal push block 353 no longer push the push rod 354. At this time, the push rod 354 rotates downward under the action of its own gravity and the gravity of the raw material and returns to a horizontal state.

[0038] See also Figure 1 , Figure 2 and Figure 6The up and down moving component 44 includes a rotating shaft 441 rotatably installed on the left and right sides of the support frame 41. One end of the rotating shaft 441 passes through the inner side of the support frame 41 and is connected to the central shaft 31 through a bevel gear set. The other end of the rotating shaft 441 is coaxially fixedly connected with a turntable 442. The edge of the turntable 442 away from the support frame 41 is rotatably connected with a cylinder 443. The left and right sides of the slip ring 43 are symmetrically fixedly connected with pull rods 444. The top end of the pull rod 444 slides through the top of the tank cover 2 and is fixedly connected with a groove frame 445. The cylinder 443 is slidably installed inside the corresponding groove frame 445.

[0039] The central shaft 31 and the stirring rod 2 36 are driven to rotate by the driving motor 42, and then the central shaft 31 drives the movable sleeve 32 and the stirring rod 1 33 to rotate, so that the stirring rod 1 33 stirs and mixes the raw materials. During the rotation of the central shaft 31, the rotating shaft 441 and the turntable 442 are driven to rotate by the bevel gear set. When the turntable 442 rotates, it will drive the cylinder 443 to rotate, and the cylinder 443 is used to push the groove frame 445 to move up and down. During the up and down movement of the groove frame 445, the pull rod 444 is used to pull the slip ring 43 up and down, and the slip ring 43 is used to drive the movable sleeve 32 to move back and forth up and down, so that the stirring rod 1 33 moves up and down during the circumferential rotation of the movable sleeve 32, thereby improving the stirring effect. At the same time, during the up and down movement of the stirring rod 1 33, the two support plates 34 thereon are converted between horizontal and V-shaped.

[0040] See also Figure 2 and Figure 3 A support assembly 37 for supporting the stirring rod 1 33 is also installed on the stirring rod 2 36. The support assembly 37 includes a movable sleeve 371 slidably sleeved on the outside of the stirring rod 2 36. An oblique support rod 372 is hinged between the top of the movable sleeve 371 and the bottom of the end of the lowest stirring rod 1 33 away from the movable shaft sleeve 32. The oblique support rod 372 is hinged to the corresponding movable sleeve 371 and the stirring rod 1 33. An elastic telescopic rod 1 373 located below the stirring rod 2 36 is fixedly connected between the movable sleeve 371 and the central axis 31. A support rod 374 is fixedly connected between the sides of the two adjacent stirring rods 1 33 away from the movable shaft sleeve 32. An elastic telescopic rod 2 375 is fixedly connected to the top of the end of the uppermost stirring rod 1 33 away from the movable shaft sleeve 32. A ball bearing is rotatably installed on the top of the telescopic section of the elastic telescopic rod 2 375.

[0041] The elastic telescopic rod 373 is used to give the movable sleeve 371 an elastic force to move in the direction away from the movable shaft sleeve 32. The movable sleeve 371, the stirring rod 36 and the diagonal support rod 372 cooperate to support the lowermost stirring rod 33, and the triangular stable structure is used to increase the supporting strength. The support rod 374 is used to support the two adjacent stirring rods 33, so as to improve the firmness and stability of the stirring rod 33 away from the movable shaft sleeve 32. When the movable shaft sleeve 32 and the stirring rod 33 move upward, the diagonal support rod 372 is driven by the stirring rod 33 hinged thereto to move, and the movable sleeve 371 is moved along the stirring rod 36 by the diagonal support rod 372. At the same time, the resilience of the elastic telescopic rod 373 is used to assist in pushing the movable sleeve 371 to move in the direction away from the movable shaft sleeve 32, thereby improving the smoothness of the movement of the movable sleeve 371 and ensuring that the diagonal support rod 372 can always maintain support for the lowermost stirring rod 33 without affecting the upward movement of the stirring rod 33.

[0042] See also Figure 2 , Figure 3 , Figure 7 and Figure 8 The top limiting mechanism 5 includes a plurality of arc plates 51 evenly distributed on the inner wall of the fermentation tank 1 in the circumferential direction. The arc plates 51 are slidably installed on the inner wall of the fermentation tank 1 along the radial direction of the fermentation tank 1. The bottom of the arc plate 51 is provided with an arc groove 52 coaxial with the fermentation tank 1. The arc groove 52 is slidably matched with the ball bearing on the top of the elastic telescopic rod 2 375. The bottom of the inner arc surface of the arc plate 51 is chamfered. The top of the fermentation tank 1 is evenly circumferentially and slidably installed with a plurality of wedge blocks. A wedge block 53 is located on the outer side of the arc plate 51 and its lower end surface is an inclined surface matched with the arc plate 51. A return spring 54 is fixedly connected between the lower side of one end of the arc plate 51 away from the center of the fermentation tank 1 and the inner wall of the fermentation tank 1. A groove is provided on the side of the wedge block 53 away from the arc plate 51. A baffle plate 55 located inside the groove is fixedly connected to the inner wall of the fermentation tank 1. A return spring 2 56 is fixedly connected between the top of the baffle plate 55 and the inner wall of the groove.

[0043] In the initial state, the return spring 1 54 pushes the arc plate 51 away from the center of the fermentation tank 1, so that the arc plate 51 retracts into the inner wall of the fermentation tank 1 to avoid affecting the insertion of the stirring rod 1 33 and the stirring rod 2 36 into the fermentation tank 1.

[0044] When the stirring mechanism 3 is completely placed in the fermentation tank 1, the tank cover 2 is closed on the top of the fermentation tank 1. In this process, the tank cover 2 is used to push the wedge block 1 53 downward, and the wedge block 1 53 pushes the arc plate 51 to move toward the center of the fermentation tank 1. At this time, the return spring 2 56 and the return spring 1 54 will be compressed. When the arc plate 51 moves toward the center of the fermentation tank 1, the elastic telescopic rod 2 375 is compressed downward under the push of the bottom of the inner arc surface of the arc plate 51, and the ball at the top of the elastic telescopic rod 2 375 contacts the arc plate. 51 bottom surface, when the arc plate 51 is completely moved out, several arc plates 51 are pieced together to form a ring shape, and the ball on the top of the elastic telescopic rod 2 375 just enters the arc groove 52, and the arc groove 52 is used to guide and limit the elastic telescopic rod 2 375 during rotation, and then the stirring rod 1 33, the support plate 34, the stirring rod 2 36, the movable shaft sleeve 32 and other structures are implemented with rotation guidance and limitation, and at the same time, the elastic telescopic rod 2 375 is used to press and limit the uppermost stirring rod 1 33, so as to improve the stability of the stirring rod 1 33 during rotation.

[0045] See also Figure 1 , Figure 2 , Fig. 9 and Fig.10 The bottom limiting mechanism 6 includes a movable ring 61 rotatably mounted on the inner wall of the fermentation tank 1 and having the same height as the second stirring rod 36. A limiting groove 62 matching the second stirring rod 36 is provided on the inner side of the movable ring 61. The upper end of the limiting groove 62 is open. The number of limiting grooves 62 is equal to the number of the second stirring rod 36. A movable block 63 for limiting the second stirring rod 36 is slidably mounted inside the limiting groove 62 along the radial direction of the movable ring 61. A pushing component 64 for pushing the movable block 63 to slide is installed on the movable ring 61. A reference rod is installed at the bottom of the tank cover 2. A U-shaped reference seat is installed at the position of the reference rod corresponding to the outer ring wall of the fermentation tank 1. The reference rod and the reference seat cooperate to ensure that before the second stirring rod 36 enters the fermentation tank 1, the end of the second stirring rod 36 is already opposite to the limiting groove 62 up and down, and the placement of the stirring mechanism 3 is guided and limited to ensure that the placement position is accurate.

[0046] See also Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 The pushing assembly 64 includes a wedge block 641 fixedly mounted on the side of the movable block 63 away from the center of the movable ring 61, a wedge ring 642 is slidably mounted on the top of the movable ring 61, the cross section of the wedge ring 642 is a wedge-shaped structure, the bottom of the wedge ring 642 is an inclined surface and slides with the inclined surface of the wedge block 641, a return spring 643 sleeved on the outside of the movable block 63 is fixedly connected between the wedge block 641 and the inner wall of the movable ring 61, and a pushing component for pushing the wedge ring 642 to move downward is installed in the inner wall of the fermentation tank 1.

[0047] In the initial state, the return spring three 643 is used to push the wedge block two 641 and the movable block 63 to move in the direction away from the center of the fermentation tank 1, so that the movable block 63 retracts into the inside of the movable ring 61, and the movable block 63 prevents the movable block 63 from affecting the falling of the stirring rod two 36; when placing the stirring mechanism 3 into the fermentation tank 1, the lower end of the reference rod on the tank cover 2 is first inserted into the reference seat on the fermentation tank 1. At this time, the end of the stirring rod two 36 away from the central axis 31 is aligned with the opening above the limiting groove 62, and then the stirring mechanism 3 is placed into the fermentation tank 1, and the end of the stirring rod two 36 away from the central axis 31 just falls into the limiting groove 62. The limiting groove 62 is used to limit the stirring rod two 36, so that the stirring rod two 36 and the movable ring 61 are spliced ​​together, and the subsequent movable ring 61 can rotate synchronously with the stirring rod two 36, and the movable ring 61 is used to support and guide the stirring rod two 36, so as to improve the stability of the stirring rod two 36 during rotation, that is, to improve the stability of the stirring structure as a whole.

[0048] See also Figure 2 , Figure 8 , Fig. 9 and Fig.10 The pushing component includes a pressure rod 644 which is slidably installed in the inner wall of the fermentation tank 1 and is located above the wedge ring 642. The top of the pressure rod 644 penetrates to the top of the fermentation tank 1. A baffle plate 2 645 is fixedly connected to the pressure rod 644. The baffle plate 2 645 is slidably connected to the fermentation tank 1 up and down. A return spring 4 646 is fixedly connected between the bottom of the baffle plate 2 645 and the inner wall of the fermentation tank 1.

[0049] When the stirring rod 2 36 is completely placed in the limiting groove 62, the tank cover 2 just covers the top of the fermentation tank 1, and the tank cover 2 is used to press the pressure rod 644 downward, and the pressure rod 644 moves downward and pushes the wedge ring 642 to move downward. The wedge ring 642 is used to push the wedge block 2 641 and the movable block 63 to move closer to the center of the fermentation tank 1. At this time, the return spring 3 643 will be compressed, and the movable block 63 will be inserted into the stirring rod 2 36 to lock it, thereby improving the firmness of the splicing of the stirring rod 2 36 and the movable ring 61.

[0050] See also Figure 2 and Figure 3 A plurality of scraper plates 38 are evenly installed around the bottom end of the central shaft 31 . The scraper plates 38 are located below the stirring rod 36 . The bottom of the scraper plates 38 contacts the bottom wall of the inner cavity of the fermentation tank 1 .

[0051] See also Figure 2 , Figure 3 , Fig. 9 and Fig.10The bottom of the movable ring 61 is integrally formed with a retaining bar 65 located directly below the limiting groove 62. A positioning groove 651 whose top is connected to the bottom of the limiting groove 62 is opened on the side of the retaining bar 65 close to the center of the movable ring 61. The end of the scraper plate 38 away from the center of the movable shaft sleeve 32 is fixedly connected with a protrusion 381, and the protrusion 381 is slidably matched with the positioning groove 651.

[0052] When the stirring rod 36 is placed in the limiting groove 62, the protrusion 381 slides downward into the alignment groove 651, so that the baffle 65 and the scraper plate 38 are spliced ​​together. The baffle 65 is used to limit the scraper plate 38 to improve the stability of the scraper plate 38. When the material is to be discharged, the scraper plate 38 can scrape the raw materials on the bottom wall of the fermentation tank 1 to assist the discharge of the raw materials.

[0053] See also Figure 1-Figure 10 When in use, in step 1, in the initial state, the movable shaft sleeve 32 is at the lowest position within the range of vertical movement, and the arc plate 51 is retracted into the inner wall of the fermentation tank 1 to avoid affecting the insertion of the stirring rod 1 33 and the stirring rod 2 36 into the fermentation tank 1. When the stirring mechanism 3 is installed into the fermentation tank 1, the lower end of the reference rod on the tank cover 2 is first inserted into the reference seat on the fermentation tank 1. At this time, the end of the stirring rod 2 36 away from the central axis 31 is aligned with the opening above the limiting groove 62, and then the stirring mechanism 3 is placed in the fermentation tank 1, so that the protrusion 381 slides downward into the alignment groove 651, so that the baffle 65 and the scraper plate 38 are spliced ​​together, and at the same time, the end of the stirring rod 2 36 away from the central axis 31 just falls into the limiting groove 62, and the limiting groove 62 is used to limit the stirring rod 2 36. At this time, the tank cover 2 is closed on the fermentation tank 1, and the fermentation tank 1 and the tank cover 2 are fixed together with bolts.

[0054] Step 2. When the tank cover 2 is closed on the top of the fermentation tank 1, the tank cover 2 is used to press the pressure rod 644 downward, and the pressure rod 644 moves downward and pushes the wedge ring 642 to move downward. The wedge ring 642 is used to push the wedge block 2 641 and the movable block 63 to move closer to the center of the fermentation tank 1. At this time, the return spring 3 643 will be compressed, and the movable block 63 will be inserted into the stirring rod 2 36 to fix it, preventing the stirring rod 2 36 from moving upward and falling off.

[0055] Step three, when the tank cover 2 is closed on the top of the fermentation tank 1, the tank cover 2 is used to push the wedge block 1 53 to move downward, and the wedge block 1 53 then pushes the arc plate 51 to move toward the center of the fermentation tank 1. At this time, the return spring 2 56 and the return spring 1 54 will be compressed. When the arc plate 51 moves toward the center of the fermentation tank 1, the elastic telescopic rod 2 375 is compressed downward under the push of the bottom of the inner arc surface of the arc plate 51, and the ball at the top of the elastic telescopic rod 2 375 contacts the bottom surface of the arc plate 51. When the arc plate 51 is completely moved out, several arc plates 51 are pieced together to form a circular ring, and the ball at the top of the elastic telescopic rod 2 375 just enters the arc groove 52. The arc groove 52 is used to guide and limit the elastic telescopic rod 2 375 during rotation, and then the stirring rod 1 33, the support plate 34, the stirring rod 2 36, the movable shaft sleeve 32 and other structures are implemented with rotation guidance and limitation.

[0056] Step 4, adding raw materials into the fermentation tank 1 for fermentation. During the fermentation process, the central shaft 31 and the stirring rod 2 36 are driven to rotate by the driving motor 42, and then the central shaft 31 drives the movable shaft sleeve 32 and the stirring rod 1 33 to rotate, so that the stirring rod 1 33 stirs and mixes the raw materials. During the rotation of the central shaft 31, the rotating shaft 441 and the turntable 442 are driven to rotate by the bevel gear set. When the turntable 442 rotates, it drives the cylinder 443 to rotate. The cylinder 443 is used to push the groove frame 445 to move up and down. During the up and down movement of the groove frame 445, the pull rod 444 is used to pull the slip ring 43 up and down, and the slip ring 43 is used to drive the movable shaft sleeve 32 to move back and forth up and down, thereby improving the stirring effect.

[0057] Step 5. When the movable sleeve 32 moves upward along the central axis 31, the rack 356 is used to drive the gear 355 and the threaded rod 352 to rotate, and then the threaded rod 352 drives the trapezoidal push block 353 to move away from the movable sleeve 32. The inclined edges on both sides of the trapezoidal push block 353 are used to push the push rod 354 and the support plate 34 to rotate upward, so that the support plates 34 on both sides of the stirring rod 33 are converted into a V shape, and the support plates 34 are used to transport the raw materials of the lower layer upward to fully mix the raw materials of the upper and lower layers.

[0058] Step 6. When the movable sleeve 32 moves downward along the central axis 31, the rack 356 is used to drive the gear 355 and the threaded rod 352 to rotate in the opposite direction, and then the threaded rod 352 drives the trapezoidal push block 353 to move toward the direction close to the movable sleeve 32. After losing the support of the trapezoidal push block 353, the support plate 34 will rotate downward under the action of its own gravity, so that the support plates 34 on both sides of the stirring rod 33 are converted into a straight line.

[0059] Step 7: After fermentation is completed, the discharge port is opened to discharge the fermented material in the fermentation tank 1 downwards. At the same time, the central shaft 31 is driven to rotate by the driving motor 42 so that the scraper plate 38 scrapes the raw materials at the bottom of the fermentation tank 1 and discharges the raw materials at the bottom of the fermentation tank 1 from the discharge port.

[0060] Step eight, after the unloading is completed, the tank cover 2 is opened. After the pressure of the tank cover 2 is lost, the rebound force of the return spring four 646 is used to push the baffle plate two 645 and the pressure rod 644 to move upward. After the pressure of the pressure rod 644 is lost, the rebound force of the return spring three 643 is used to push the wedge block two 641 and the movable block 63 to move away from the center of the fermenter 1, and the lock of the stirring rod two 36 is released. At the same time, the return spring two 56 pushes the wedge block one 53 to move upward. After the pushing of the wedge block one 53 is lost, the return spring one 54 pushes the arc plate 51 to move away from the center of the fermenter 1, so that the arc plate 51 retracts into the inner wall of the fermenter 1, and finally the stirring mechanism 3 is taken out from the inside of the fermenter 1 for cleaning.
