Description

Technical Field

[0001] This invention relates to the field of fermentation technology, and specifically to a fermentation apparatus for manufacturing red yeast rice slices. Background Technology

[0002] Red yeast rice slices are a commonly used traditional Chinese medicine for promoting blood circulation and digestion in clinical practice and daily conditioning, and have good medicinal value. The production of red yeast rice slices involves a fermentation process. The traditional method is to put rice into a fermentation tank, add red yeast rice bacteria, and then workers use a stirring rod to mix it. However, this stirring method results in high labor intensity for workers and poor mixing effect.

[0003] To address the aforementioned issues, Chinese Patent CN212713476U discloses a preparation device for a blood sugar-lowering fermented red yeast rice functional food. The device includes a cylindrical body with a stirring rod inside. The top of the stirring rod penetrates the top of the cylindrical body and is fitted with a gear. The top of the stirring rod is rotatably connected to the top of the cylindrical body via a bearing. Stirring blades are fixedly fixed at equal intervals on the surface of the stirring rod. A horizontal plate is positioned above the cylindrical body, and uprights are fixed at the four corners of the bottom of the horizontal plate. The bottoms of the uprights are all fixedly connected to the top of the cylindrical body. This preparation device can thoroughly mix rice and red yeast rice without manual labor, thus reducing the labor intensity of workers, ensuring effective mixing, and improving product quality.

[0004] The above-mentioned preparation device has the following problems during actual use: the stirring rod drives multiple stirring blades to rotate to achieve stirring and mixing, but the position of the stirring blades cannot be changed, that is, it can only ensure the stirring and mixing effect of the material near the stirring blades, while the material near the side wall and bottom of the cylinder cannot be stirred and mixed, resulting in uneven stirring and mixing. Summary of the Invention

[0005] The present invention aims to provide a fermentation device for manufacturing red yeast rice slices, so as to solve the problem of uneven mixing in the existing preparation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fermentation device for manufacturing red yeast rice slices, comprising a fermentation box, a feeding channel and a discharging channel connected to the fermentation box, a sealing block detachably connected to the discharging channel, and a heater provided on the fermentation box; a partition is provided inside the fermentation box, a rotating shaft is rotatably connected to the partition, a stirring assembly is provided on the rotating shaft, the stirring assembly includes a movable sleeve and a groove vertically opened on the side wall of the rotating shaft, the rotating shaft passes through the inner ring of the movable sleeve, the movable sleeve can move vertically, and stirring blocks are provided on both ends of the side wall of the movable sleeve; a slider is slidably connected in the groove, and the slider is fixedly connected to the inner wall of the movable sleeve; it also includes a drive assembly for driving the rotating shaft to rotate and a linkage assembly for driving the slider to reciprocate vertically as the rotating shaft rotates.

[0007] The principles and advantages of this scheme are: 1. Rice and red yeast are introduced into the fermentation chamber through the feeding channel. The drive component drives the rotating shaft to rotate, which in turn drives the movable sleeve to rotate synchronously. The movable sleeve drives the two stirring blocks to rotate, thereby achieving the mixing of rice and red yeast.

[0008] 2. During the rotation of the shaft, the linkage component can drive the slider to move vertically back and forth along the chute path. The slider drives the movable sleeve to move vertically back and forth, and the movable sleeve drives the two stirring blocks to move vertically back and forth. This allows the position to be changed at different heights, expands the stirring range, promotes the stirring and mixing of rice and red yeast, and ensures uniform stirring and mixing of rice and red yeast.

[0009] Furthermore, the inner wall of the movable sleeve comes into frictional contact with the outer wall of the rotating shaft.

[0010] The above settings prevent rice and red yeast from entering the gap between the movable sleeve and the rotating shaft.

[0011] Furthermore, the linkage assembly includes a first cylindrical cam coaxially connected to the rotating shaft, an axial hole at the end of the rotating shaft, a first curved groove on the first cylindrical cam, a linkage block slidably connected to the first curved groove, the linkage block being vertically slidably connected to the partition plate, a shaft being fixedly connected to the end of the linkage block away from the first curved groove, the shaft extending into the axial hole, and the shaft being able to move vertically within the axial hole; the axial hole communicates with the slide groove, an annular block is rotatably connected to the shaft, and the slider is fixedly connected to the annular block.

[0012] With the above configuration, during the rotation of the shaft, the shaft drives the two stirring blocks to rotate through the slider and the movable sleeve. At the same time, the shaft drives the annular block to rotate on the shaft through the slider.

[0013] During the rotation of the shaft, the shaft drives the first cylindrical cam to rotate. The first cylindrical cam drives the linkage block to reciprocate vertically through the first curved groove. The linkage block drives the shaft to reciprocate vertically within the axial hole. The shaft drives the slider to reciprocate vertically through the annular block. The slider drives the movable sleeve to reciprocate vertically.

[0014] Furthermore, the side wall of the stirring block is provided with a side groove, and an extension block is slidably connected in the side groove. The extension block is provided with an extension plate; it also includes an adjustment component for simultaneously driving the two extension blocks to reciprocate along the radial direction of the rotating shaft.

[0015] With the above setup, during the rotation of the mixing block, the mixing block drives the extension block and extension plate to rotate synchronously, thereby expanding the mixing range and promoting the mixing of rice and red yeast.

[0016] By adjusting the components, two extension blocks can be driven to reciprocate along the radial direction of the rotating shaft simultaneously. The extension blocks drive the extension plate to reciprocate synchronously, thereby changing the position of the extension blocks and extension plates along the radial direction of the rotating shaft, expanding the mixing range, and promoting the mixing of rice and red yeast.

[0017] Furthermore, the adjustment assembly includes an inner chamber opened inside the stirring block, an adjustment shaft rotatably connected to the inner chamber, a second cylindrical cam coaxially connected to the adjustment shaft, a second curved groove provided on the second cylindrical cam, an adjustment block slidably connected in the second curved groove, and an end of the adjustment block away from the second curved groove fixedly connected to the extension block; it also includes an adjustment unit that simultaneously drives the two adjustment shafts to reciprocate.

[0018] With the above settings, the adjustment unit simultaneously drives two adjustment shafts to reciprocate, the adjustment shafts drive the second cylindrical cam to reciprocate, and the second cylindrical cam drives the extension block and extension plate to reciprocate along the radial direction of the rotating shaft through the second curved groove and the adjustment block.

[0019] Furthermore, the adjustment unit includes a wall block fixed to the outer wall of the rotating shaft, a wall hole opened on the side wall of the movable sleeve, a vertical hole opened on the stirring block, an adjustment gear coaxially connected to the rotating shaft, and a baffle fixed in the inner chamber. The wall block passes through the wall hole and can move relative to each other within the wall hole. A vertical block is provided on the wall block, and the vertical block passes through the vertical holes on the two stirring blocks. A rack is provided on both ends of the side wall of the vertical block, and the vertical block and the rack can move relative to each other within the vertical hole. The vertical hole communicates with the inner chamber, the adjustment shaft is rotatably connected to the baffle, and the adjustment gear meshes with the rack.

[0020] With the above settings, during the vertical reciprocating motion of the movable sleeve, the movable sleeve drives the two stirring blocks to reciprocate vertically, while the wall block moves vertically relative to each other in the wall groove, and the vertical block and the rack move vertically relative to each other in the vertical hole, so that the rack meshes with the adjusting gear and drives the adjusting shaft to rotate reciprocally.

[0021] Furthermore, the stirring block is provided with support blocks on both sides of the end away from the movable sleeve, the extension block is located between the two support blocks, and the support blocks are connected to arc-shaped blocks.

[0022] With the above setup, during the rotation of the mixing block, the mixing block drives the support block to rotate synchronously, and the support block drives the arc-shaped block to rotate synchronously, thereby expanding the mixing range and promoting the mixing of rice and red yeast.

[0023] Furthermore, the support block is provided with a side groove, and a side block is slidably connected in the side groove; the arc-shaped block is elastic, one end of the arc-shaped block is fixedly connected to the support block, and the other end of the arc-shaped block is fixedly connected to the side block; the two end side walls of the extension plate are provided with transverse blocks, and the end of the transverse block away from the extension plate is provided with a U-shaped block, and the two ends of the U-shaped block abut against the two sides of the side block respectively.

[0024] With the above setup, during the reciprocating motion of the extension plate along the radial direction of the rotating shaft, the extension plate drives the U-shaped block to reciprocate through the transverse block, which in turn drives the movable end of the arc-shaped block to reciprocate through the side block, causing the distance between the two ends of the arc-shaped block to continuously change. When the distance between the two ends of the arc-shaped block is at its maximum, the distance between the protrusion of the arc-shaped block and the extension block is at its minimum. When the distance between the two ends of the arc-shaped block is at its minimum, the distance between the protrusion of the arc-shaped block and the extension block is at its maximum. Therefore, by changing the position of the protrusion of the arc-shaped block, the mixing range can be expanded, promoting the mixing of rice and red yeast rice.

[0025] Furthermore, a guide groove is provided on the side of the support block near the extension block, and the extension block is slidably connected to the guide groove.

[0026] With the above configuration, the guide groove can extend the movement of the block, providing guidance and support, and improving structural stability. Attached Figure Description

An arc-shaped block 71 is connected to the support block 70. Specifically, the support block 70 has a side groove 72, and a side block 73 is slidably connected in the side groove 72. The arc-shaped block 71 is elastic and is an elastic iron sheet.

[0035] The specific implementation process is as follows: In use, rice and red yeast rice are introduced into the fermentation chamber 10 through the feed channel 11; the heater 14 and motor 22 are started. The heater 14 can raise the temperature inside the fermentation chamber 10 to promote fermentation; the output shaft of the motor 22 drives the drive gear 23 to rotate, and the drive gear 23 meshes with the driven gear 24 to drive the rotating shaft 21 to rotate. The rotating shaft 21 drives the movable sleeve 30 to rotate synchronously, and the movable sleeve 30 drives the two stirring blocks 32 to rotate, thereby realizing the stirring and mixing of rice and red yeast rice; during the rotation of the rotating shaft 21, the rotating shaft 21 drives the ring U-shaped block 75 to rotate on the shaft 43 through the slider 33.

[0036] During the rotation of the mixing block 32, the mixing block 32 drives the extension block and extension plate 51 to rotate synchronously, thereby expanding the mixing range and promoting the mixing of rice and red yeast. During the rotation of the mixing block 32, the mixing block 32 drives the support block 70 to rotate synchronously, and the support block 70 drives the arc block 71 to rotate synchronously, thereby expanding the mixing range and promoting the mixing of rice and red yeast.

[0037] During the rotation of the rotating shaft 21, the rotating shaft 21 drives the first cylindrical cam 40 to rotate. The first cylindrical cam 40 drives the linkage block 42 to move vertically and reciprocally through the first curved groove. The linkage block 42 drives the shaft 43 to move vertically and reciprocally within the axial hole 41. The shaft 43 drives the slider 33 to move vertically and reciprocally through the ring U-shaped block 75. The slider 33 drives the movable sleeve 30 to move vertically and reciprocally. The movable sleeve 30 drives the two stirring blocks 32 to move vertically and reciprocally. The stirring blocks 32 drive the extension block, extension plate 51 and arc block 71 to move vertically and reciprocally. In this way, the position can be changed in height, the stirring range can be expanded, and the mixing of rice and red yeast can be promoted.

[0038] During the vertical reciprocating motion of the movable sleeve 30, the movable sleeve 30 drives the two stirring blocks 32 to reciprocate vertically. At the same time, the wall block 60 moves vertically relative to each other in the wall groove, and the vertical block 65 and the rack 66 move vertically relative to each other in the vertical hole 62. This causes the rack 66 to mesh with the adjusting gear 63, which drives the adjusting shaft 53 to rotate back and forth. The adjusting shaft 53 drives the second cylindrical cam 54 to rotate back and forth. The second cylindrical cam 54 drives the extension block and the extension plate 51 to move back and forth along the radial direction of the rotating shaft 21 through the second curved groove and the adjusting block 55. This allows the position of the extension block and the extension plate 51 to be changed along the radial direction of the rotating shaft 21, thereby expanding the stirring range and promoting the stirring and mixing of rice and red yeast.

[0039] During the reciprocating motion of the extension plate 51 along the radial direction of the rotating shaft 21, the extension plate 51 drives the U-shaped block 75 to reciprocate through the transverse block 74, so that the U-shaped block 75 drives the movable end of the arc-shaped block 71 to reciprocate through the side block 73, causing the distance between the two ends of the arc-shaped block 71 to continuously change. When the distance between the two ends of the arc-shaped block 71 is the largest, the distance between the protrusion of the arc-shaped block 71 and the extension block is the smallest. When the distance between the two ends of the arc-shaped block 71 is the smallest, the distance between the protrusion of the arc-shaped block 71 and the extension block is the largest. Therefore, by changing the position of the protrusion of the arc-shaped block 71, the stirring range can be expanded, promoting the stirring and mixing of rice and red yeast.

[0040] After the fermentation process is complete, turn off the heater 14 and the motor 22; remove the sealing block 13 from the discharge channel 12 to obtain the fermented material.

[0041] In this embodiment, the support block 70 has a guide groove 76 on the side near the extension block, and the extension block is slidably connected to the guide groove 76. The guide groove 76 guides and supports the movement of the extension block, improving structural stability.
