A fermentation device and method for preserved vegetable production

Abstract

This invention relates to the field of pickled mustard tuber production technology, specifically to a fermentation device and method for pickled mustard tuber production. The device includes a base, two first support seats, a mounting shaft, a lifting mechanism, a mounting seat, a fermentation tank, and a driving mechanism. When the lifting mechanism lowers the tail end of the mounting seat, the mounting seat rotates around the mounting shaft, causing the opening of the fermentation tank to face upwards for easy feeding. When the lifting mechanism raises the tail end of the mounting seat to an appropriate position, the fermentation tank is in a horizontal state for fermentation. When the lifting mechanism continues to raise the tail end of the mounting seat, the opening of the fermentation tank faces downwards for easy unloading. During fermentation, the fermentation tank rotates around its own axis, and the material inside the tank tumbles and shifts under gravity, achieving material turning. This solves the technical problem that existing vertical fermentation tanks using mechanical stirring devices cause shear damage to the pickled mustard tuber, disrupting the integrity of the pieces and leading to an increased proportion of broken pieces in the finished product.

Description

Technical Field

[0001] This invention relates to the field of pickled mustard tuber production technology, and in particular to a fermentation device and method for pickled mustard tuber production. Background Technology

[0002] The production of pickled mustard tubers requires fermentation of the materials. During fermentation, the materials are usually turned over to ensure that they come into full contact with the salt and fermentation agents, and to ensure that the temperature and humidity inside the tank are evenly distributed.

[0003] In some technologies, this fermentation process commonly uses vertical fermenters, with mechanical stirring devices installed inside the tanks to achieve material turning. The stirring device typically consists of a motor, a stirring shaft extending into the tank, and stirring blades mounted on the shaft. The rotation of the blades propels the material to move.

[0004] However, when using the aforementioned mechanical stirring method for turning the material, the stirring blades exert shearing and impact forces on the material. After fermentation, the pickled mustard tuber has a brittle and tender texture, making it extremely easy to break or grind during this process, thus compromising its shape and resulting in a significantly higher proportion of broken pieces in the finished product, reducing its grade and commercial value. Summary of the Invention

The system comprises multiple first springs 40305, two support blocks 40306, two contact blocks 40307, ​​two locking rods 40308, and two second springs 40309; both ends of the pressure block 40304 are provided with first inclined surfaces 4030401; the contact block 40307 is provided with second inclined surfaces 4030701; each of the vertical rails 402 has multiple locking holes 40201 evenly spaced from top to bottom on its side; the lifting component 405 includes a top plate 40501, two guide rods 40502, a slider 40503, a lead screw 40504, and a first reduction motor 40505; the driving mechanism 7 includes a top frame 701, a second reduction motor 702, a rotating shaft 703, a gear 704, and a gear ring 705; the aforementioned solution solves the technical problem that when the existing vertical fermentation tank 6 uses a mechanical stirring device to turn the material, the stirring blades cause shearing damage to the pickled mustard tuber, destroy the integrity of the block shape, and lead to an increase in the proportion of broken material in the finished product.

[0030] Furthermore, two first support seats 2 are fixedly disposed on the top of the base 1; the mounting shaft 3 is fixedly disposed between the two first support seats 2; the lifting mechanism 4 is disposed on the top of the base 1; the front end of the mounting seat 5 is rotatably connected to the mounting shaft 3, and the rear end of the mounting seat 5 is connected to the lifting mechanism 4, the lifting mechanism 4 being used to drive the rear end of the mounting seat 5 to rise and fall; the fermentation tank 6 is rotatably disposed on the mounting seat 5; the fermentation tank 6 can rotate around its own axis; the driving mechanism 7 is disposed on the side of the fermentation tank 6, and is used to drive the fermentation tank 6 to rotate.

[0031] In this embodiment, the mounting shaft 3 is horizontally fixed between the two first support seats 2, serving as the pivot for the pitching and swinging of the mounting seat 5. The front end of the mounting seat 5 is rotatably connected to the mounting shaft 3, allowing the mounting seat 5 to rotate around the mounting shaft 3. The rear end of the mounting seat 5 is connected to the lifting mechanism 4, which drives the rear end of the mounting seat 5 to move up and down. When the lifting mechanism 4 lowers the rear end of the mounting seat 5, the mounting seat 5 rotates around the mounting shaft 3, and its front end tilts upward, so that the opening of the fermentation tank 6 faces upward, facilitating material feeding; when the lifting mechanism 4 raises the rear end of the mounting seat 5 to an appropriate position, the mounting seat 5 is in a horizontal state, and the fermentation tank 6 is in a horizontal state for fermentation; when the lifting mechanism 4 continues to raise the rear end of the mounting seat 5, the front end of the mounting seat 5 tilts downward, so that the opening of the fermentation tank 6 faces downward, facilitating material unloading. The fermentation tank 6 is rotatably mounted on the mounting seat 5 around its own axis. The drive mechanism 7 is located on the side of the fermentation tank 6 and is used to drive the fermentation tank 6 to rotate around its own axis to agitate the material inside. During fermentation, the fermentation tank 6 rotates around its own axis, and the material inside rolls and shifts under the action of gravity, thus achieving material agitation. This material agitation method eliminates the need for any stirring blades inside the tank. The material comes into contact with each other during the rolling process rather than being cut by shearing components, thereby solving the technical problem that when existing vertical fermentation tanks 6 use mechanical stirring devices for material agitation, the stirring blades cause shearing damage to the pickled mustard tuber, destroy the integrity of the block shape, and lead to an increased proportion of broken material in the finished product.

[0032] Furthermore, two auxiliary support mechanisms 8 are disposed on the top of the base 1 to assist in supporting the tail end of the mounting base 5 when the mounting base 5 is horizontal during the fermentation process.

[0033] In this embodiment, during the fermentation process, when the mounting base 5 is adjusted to a horizontal state, the two auxiliary support mechanisms 8 support the tail end of the mounting base 5 from both sides, sharing the load of the lifting mechanism 4, improving the stability and safety of the support during long-term fermentation, and reducing the wear of the lifting mechanism 4 under long-term static load.

[0034] Furthermore, a meshing hole 501 is provided on each side of the tail end of the mounting base 5; the second support base 801 is fixedly mounted on the top of the base 1; the cylinder 802 is fixedly mounted on the second support base 801; the meshing block 803 is slidably mounted in the second support base 801 and is fixedly connected to the output end of the cylinder 802.

[0035] In this embodiment, when the mounting base 5 is adjusted to a horizontal position, the cylinder 802 drives the engaging block 803 to extend and insert into the engaging hole 501, forming a mechanical engagement support. At this time, the tail end of the mounting base 5 is supported not only by the lifting mechanism 4 but also by the engaging blocks 803 on both sides. When it is necessary to change the posture, the cylinder 802 first drives the engaging block 803 to retract and disengage from the engaging hole 501 before the lifting mechanism 4 can operate.

[0036] Furthermore, the two anti-detachment mechanisms 9 are fixedly mounted on the fermentation tank 6 to prevent the fermentation tank 6 from detaching from the mounting base 5.

[0037] In this embodiment, two anti-detachment mechanisms 9 are fixedly mounted on the fermentation tank 6 to prevent the fermentation tank 6 from detaching from the mounting base 5 during rotation or when the mounting base 5 is tilted. The anti-detachment mechanism 9 limits the axial movement of the fermentation tank 6, ensuring that the fermentation tank 6 remains in the predetermined mounting position on the mounting base 5 in any posture.

[0038] Furthermore, the mounting ring 901 is fixedly mounted on the fermentation tank 6; the plurality of ball bearings 902 are rotatably mounted inside the mounting ring 901.

[0039] In this embodiment, the mounting ring 901 is an annular structure and is fixedly sleeved on the outer periphery of the fermentation tank 6. A plurality of ball bearings 902 are rotatably disposed within the mounting ring 901, with portions of each ball bearing 902 protruding from the surface of the mounting ring 901 and making rolling contact with the mounting base 5. When the driving mechanism 7 drives the fermentation tank 6 to rotate, the mounting ring 901 rotates together with the fermentation tank 6, and the ball bearings 902 roll within the raceways of the mounting base 5. This achieves both axial positioning of the fermentation tank 6, preventing it from axially shifting and detaching from the mounting base 5, and ensures smooth rotation.

[0040] Furthermore, the two connecting rods 401 are fixedly disposed on both sides of the tail end of the mounting base 5; the two vertical rails 402 are fixedly disposed on the top of the base 1; the lifting block 403 is slidably disposed between the two vertical rails 402; the two connecting blocks 404 are fixedly disposed on the lifting block 403; each connecting block 404 is provided with a strip-shaped opening 40401; the connecting rod 401 passes through the strip-shaped opening 40401; the lifting component 405 is disposed on the top of the base 1 and is used to drive the lifting block 403 to rise and fall.

[0041] In this embodiment, two connecting rods 401 are fixedly disposed on both sides of the tail end of the mounting base 5, extending outwards. Two vertical rails 402 are vertically fixedly disposed on the top rear end of the base 1, and are arranged parallel to each other. The lifting block 403 is slidably disposed between the two vertical rails 402, and can slide up and down along the vertical rails 402. Two connecting blocks 404 are fixedly disposed on both sides of the lifting block 403. Each connecting block 404 has a strip-shaped opening 40401, which extends horizontally. The connecting rod 401 passes through the strip-shaped opening 40401 on the corresponding side, and can slide and rotate within the strip-shaped opening 40401. The lifting member 405 is disposed on the top of the base 1 and connected to the lifting block 403, and is used to drive the lifting block 403 to rise and fall along the vertical rail 402. When the lifting block 403 rises or falls, the docking block 404 drives the docking rod 401 to move through the strip opening 40401, thereby driving the tail end of the mounting base 5 to rise or fall. The strip opening 40401 provides compensation space for the horizontal displacement generated by the docking rod 401 during the pitching process of the mounting base 5.

[0042] Furthermore, the horizontal block 40301 is slidably disposed between the two vertical rails 402; the two vertical blocks 40302 are fixedly disposed at the bottom of the horizontal block 40301; a plurality of sliding rods 40303 are slidably disposed on the horizontal block 40301 and pass through the horizontal block 40301; the top ends of the plurality of sliding rods 40303 are also fixedly connected to the lifting member 405; the pressure block 40304 is fixedly disposed at the bottom end of the plurality of sliding rods 40303; a first spring 40305 is sleeved on each sliding rod 40303, and the first spring 40305 is located between the horizontal block 40301 and the pressure block 40304; two support blocks 40306 are fixedly disposed on the top of the pressure block 40304; and a first spring 40305 is provided at both ends of the pressure block 40304. Inclined surface 4030401; a contact block 40307 is slidably disposed within each vertical block 40302; the contact block 40307 is provided with a second inclined surface 4030701; a locking rod 40308 is slidably disposed within each vertical block 40302, one end of the locking rod 40308 is fixedly connected to the contact block 40307, ​​and the other end passes through the vertical block 40302; a second spring 40309 is disposed within each vertical block 40302, the second spring 40309 is sleeved on the locking rod 40308, and is used to provide a spring force to the contact block 40307, ​​so that the second inclined surface 4030701 fits against the first inclined surface 4030401; multiple locking holes 40201 are equidistantly disposed from top to bottom on the side of each vertical rail 402.

[0043] In this embodiment, the horizontal block 40301 is slidably disposed between the two vertical rails 402. The two vertical blocks 40302 are fixedly disposed at the bottom ends of the horizontal block 40301 and extend downwards. A plurality of sliding rods 40303 are slidably disposed on the horizontal block 40301 and pass through it, allowing them to slide up and down relative to the horizontal block 40301. The top ends of the plurality of sliding rods 40303 are fixedly connected to the lifting member 405. The pressure block 40304 is fixedly disposed at the bottom ends of the plurality of sliding rods 40303. A first spring 40305 is sleeved on each sliding rod 40303, and the first spring 40305 is located between the horizontal block 40301 and the pressure block 40304. Two support blocks 40306 are fixedly disposed on the top of the pressure block 40304. A first inclined surface 4030401 is provided at both ends of the pressure block 40304. A contact block 40307 is slidably disposed within each vertical block 40302, and the contact block 40307 can slide horizontally within the vertical block 40302. The contact block 40307 is provided with a second inclined surface 4030701, the inclination angle of which corresponds to that of the first inclined surface 4030401. A locking rod 40308 is slidably disposed within each vertical block 40302, one end of the locking rod 40308 being fixedly connected to the contact block 40307, ​​and the other end passing through the vertical block 40302, extending into or out of the locking hole 40201 on the vertical rail 402. Each of the vertical blocks 40302 is provided with a second spring 40309, which is sleeved on the locking rod 40308 and provides a spring force to the contact block 40307 toward the pressure block 40304, so that the second inclined surface 4030701 and the first inclined surface 4030401 remain in contact. Each of the vertical rails 402 has a plurality of locking holes 40201 evenly spaced from top to bottom on its side.

[0044] During normal operation, the lifting component 405 suspends the horizontal block 40301 via multiple sliding rods 40303. The top of the sliding rod 40303 is pulled by the lifting component 405, and the first spring 40305 is compressed between the horizontal block 40301 and the pressure block 40304. The support block 40306 abuts against the bottom of the horizontal block 40301, supporting the horizontal block 40301 and preventing the first spring 40305 from being over-compressed and failing. The first inclined surface 4030401 at both ends of the pressure block 40304 is in contact with the second inclined surface 4030701 of the contact block 40307. At this time, the locking rod 40308 retracts into the vertical block 40302 and does not interfere with the locking hole 40201, allowing the lifting block 403 to rise and fall freely.

[0045] When the lifting component 405 fails, the sliding rod 40303 loses its upward traction, and the first spring 40305 releases its elastic potential energy, pushing the pressure block 40304 downward away from the horizontal block 40301. The pressure block 40304 slides downward, and the first inclined surface 4030401 slides downward relative to the second inclined surface 4030701, pushing the contact block 40307 to the side. The contact block 40307 pushes the locking rod 40308, causing the locking rod 40308 to overcome the elastic force of the second spring 40309 and extend outward, inserting into the lock hole 40201 at the corresponding height, mechanically locking the horizontal block 40301 in the current position, preventing the tail end of the mounting base 5 from falling further, and achieving fall protection.

[0046] Furthermore, the top plate 40501 is fixedly mounted on the top of the two vertical rails 402; the two guide rods 40502 are fixedly mounted between the top plate 40501 and the base 1; the slider 40503 is slidably mounted on the two guide rods 40502 and is fixedly connected to the top ends of the plurality of sliding rods 40303; the lead screw 40504 is rotatably mounted between the top plate 40501 and the base 1 and is threadedly connected to the slider 40503; the first reduction motor 40505 is fixedly mounted on the top of the top plate 40501, and the output end of the first reduction motor 40505 is fixedly connected to the lead screw 40504.

[0047] In this embodiment, the first reduction motor 40505 drives the lead screw 40504 to rotate, and drives the slider 40503 to move up and down along the guide rod 40502 through the threaded transmission, thereby driving the tail end of the mounting base 5 to rise and fall through the slide rod 40303 and the lifting block 403.

[0048] Furthermore, the top frame 701 is fixedly mounted on the mounting base 5; the second reduction motor 702 is fixedly mounted on the top frame 701; the rotating shaft 703 is rotatably mounted on the top frame 701 and is fixedly connected to the output end of the second reduction motor 702; the gear 704 is fixedly mounted on the rotating shaft 703; and the gear ring 705 is fixedly mounted on the fermentation tank 6 and meshes with the gear 704.

[0049] In this embodiment, the second reduction motor 702 drives the rotating shaft 703 to rotate the gear 704. Through the meshing transmission of the gear 704 and the gear ring 705, the fermentation tank 6 is driven to rotate around its own axis, thereby turning over the pickled mustard tuber material in the tank during the fermentation process.

[0050] This embodiment describes a fermentation device for pickled mustard tuber production. The mounting shaft 3 is horizontally fixed between two first support seats 2, serving as a pivot for the pitching and swinging of the mounting seat 5. The front end of the mounting seat 5 is rotatably connected to the mounting shaft 3, allowing the mounting seat 5 to rotate around the mounting shaft 3. The rear end of the mounting seat 5 is connected to a lifting mechanism 4, which drives the rear end of the mounting seat 5 to move up and down. When the lifting mechanism 4 lowers the rear end of the mounting seat 5, the mounting seat 5 rotates around the mounting shaft 3, and its front end tilts upward, so that the opening of the fermentation tank 6 faces upward, facilitating material feeding. When the lifting mechanism 4 raises the rear end of the mounting seat 5 to an appropriate position, the mounting seat 5 is horizontal, and the fermentation tank 6 is horizontal, allowing fermentation to proceed. When the lifting mechanism 4 continues to raise the rear end of the mounting seat 5, the front end of the mounting seat 5 tilts downward, so that the opening of the fermentation tank 6 faces downward, facilitating material unloading. The fermentation tank 6 is rotatably mounted on the mounting seat 5 around its own axis. The drive mechanism 7 is located on the side of the fermentation tank 6 and is used to drive the fermentation tank 6 to rotate around its own axis to agitate the material inside. During fermentation, the fermentation tank 6 rotates around its own axis, and the material inside rolls and shifts under the action of gravity, thus achieving material agitation. This material agitation method eliminates the need for any stirring blades inside the tank. The material comes into contact with each other during the rolling process rather than being cut by shearing components, thereby solving the technical problem that when existing vertical fermentation tanks 6 use mechanical stirring devices for material agitation, the stirring blades cause shearing damage to the pickled mustard tuber, destroy the integrity of the block shape, and lead to an increased proportion of broken material in the finished product.

[0051] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 9 ,in, Figure 9 This is a flowchart illustrating the second embodiment of the present invention.

[0052] The present invention provides a fermentation method for producing pickled mustard tuber, comprising the following steps: S1: The lifting mechanism 4 drives the tail end of the mounting base 5 to descend, causing the mounting base 5 to rotate around the mounting shaft 3. The front end of the mounting base 5 tilts upward, so that the opening of the fermentation tank 6 faces upward, and the pickled mustard tuber material to be fermented is loaded into the fermentation tank 6 from the opening. S2: The lifting mechanism 4 drives the tail end of the mounting base 5 to rise, adjusting the mounting base 5 to a horizontal state, and the fermentation tank 6 also becomes horizontal and begins fermentation; the drive mechanism 7 periodically drives the fermentation tank 6 to rotate around its own axis, turning the pickled mustard tuber material. S3: After fermentation is complete, the lifting mechanism 4 drives the tail end of the mounting base 5 to rise, causing the mounting base 5 to rotate around the mounting shaft 3. The front end of the mounting base 5 tilts downward, so that the opening of the fermentation tank 6 faces downward. The fermented pickled mustard tuber material is discharged from the opening of the tank under the action of gravity.
