Technical Field
[0001] This disclosure relates to the field of pickled vegetable fermentation technology, and in particular to an intelligent fermentation device for pickled vegetables and its fermentation process. Background Technology
[0002] The fermentation process of pickled vegetables is a complex biochemical process, mainly relying on the action of microorganisms (especially lactic acid bacteria) to convert sugars and other components in vegetables into acids, alcohols, esters, and other substances, thereby giving pickled vegetables their unique flavor, aroma, and long shelf life. This process is usually closely integrated with pickling and can be divided into two main stages: osmotic dehydration and microbial fermentation.
[0003] Raw Material Pretreatment and Salting (Osmosis) Selection and Preparation: Select fresh vegetables (such as radishes, cucumbers, and rapeseed), wash them thoroughly, and cut them into uniform sizes such as strips, chunks, or slices. Salting: Mix the vegetables and salt in a certain ratio (e.g., 10:1) and let them sit to marinate (usually for 24 hours or longer). The core of this stage is osmosis. Dehydration and Antibacterial Effects: The high concentration of salt will cause a large amount of water to seep out of the vegetable cells through osmotic pressure, while inhibiting the growth of most spoilage microorganisms, creating conditions for subsequent beneficial fermentation. The brine produced in this stage will be partially discharged or further processed.
[0004] Pickling and Primary Fermentation (Fermentation Process): **Soy Sauce Preparation:** Salted and dehydrated vegetable pieces (sometimes soaked in water to reduce saltiness) are placed in a sauce vat. The sauces used are typically yellow soybean paste, sweet bean sauce, or soy sauce, which not only provide saltiness but are also rich in various microorganisms (such as lactic acid bacteria and yeast) and flavor precursors. **Lactic Acid Fermentation:** This is the most crucial step in pickle fermentation. In an anaerobic or microaerobic environment, lactic acid bacteria attached to the vegetables and sauce utilize the residual sugars in the vegetables for metabolism, primarily producing lactic acid. The accumulation of lactic acid lowers the pH of the environment, creating an acidic environment that further inhibits the growth of harmful bacteria (such as spoilage bacteria), which is key to the long-term preservation of pickles. Lactic acid also contributes to the refreshing sour taste of pickles. **Other Fermentations:** In addition to lactic acid fermentation, mild alcoholic fermentation (producing ethanol) and acetic acid fermentation (producing acetic acid) may also occur. These trace products can further combine to form esters, adding complex aromas to pickles. Flavor formation: During fermentation, large molecules such as proteins and pectin in vegetables are slowly broken down by microorganisms, generating small molecules such as amino acids and peptides, which are the source of the "umami" and "savory" flavor of pickles. The flavor substances in the sauce also continue to permeate into the vegetables.
[0005] In existing fermentation devices, the first consideration is the airtightness of the fermentation process for pickled vegetables. However, it is necessary to regularly check the internal environment and fermentation status of the fermentation device, which is inconvenient for manual operation and cannot guarantee the airtightness of the fermentation device in a timely manner. Summary of the Invention

[0016] Optionally, a temperature sensor and a humidity sensor are installed inside the cabinet, an air outlet is fixed to the top of the cabinet, the air inlet and outlet are connected to the inside of the cabinet, and a control panel is fixedly installed on the side of the cabinet.
[0017] A smart fermentation process for pickled vegetables, the fermentation process comprising the following steps: (1) Place the vegetables to be fermented inside the fermentation box, open the box door, place the fermentation box on top of the first partition, and seal the top of the fermentation box through the second partition; (2) The temperature and humidity environment inside the cabinet is monitored by temperature and humidity sensors inside the cabinet, and the temperature and humidity inside the cabinet are kept suitable for fermentation by air inlet and air outlet devices. (3) Unlock the installation components and the fermentation boxes from top to bottom in sequence using the detection components on the box door, and push out the top opening of the fermentation box; (4) The detection component inserts the detection probe from the exposed opening of the fermentation chamber to detect the number of anaerobic bacteria inside the fermentation chamber; (5) Open the box door. It is possible to manually unlock the connection between a certain fermentation box and the installation components, pull out the fermentation box separately, and manually check the fermentation situation inside the fermentation box.
[0018] The technical solution provided in this disclosure may include the following beneficial effects: When the fermentation chamber needs to be sent out, the bidirectional screw is rotated to move the two friction plates. At the same time, the transmission belt drives the first bevel gear to rotate and mesh with the second bevel gear, which in turn drives the telescopic rod to rotate. This causes the stud to rotate and pass through the transverse groove, allowing the stud to make a squeezing contact with the side wall of the fermentation chamber. The locking methods of the friction plates and the stud are opposite, and there is an additional process in between, that is, the friction plates do not contact the slide rail, and the stud does not make squeezing contact with the fermentation chamber, thus facilitating the sending out of the fermentation chamber. At the same time, when the lower frame is pushed upward, the connecting rod pulls the slider to slide along the second slide groove, while the push plate slides along the first slide groove. With the help of the spring force inside the first slide groove, the fermentation chamber is pushed out. Here, it is not necessary to consider pushing out the entire fermentation chamber. Instead, with the chamber door sealed, the unlocked fermentation chamber is pushed out a short distance to allow the detection probe to be inserted. In this invention, the fermentation box is placed on the second partition, and the upper part is sealed and covered by the first and second partitions. The second partition is initially rotated by a bidirectional screw, which causes the friction plate to contact the slide rail, thereby stacking the fermentation boxes inside the cabinet. There is also a certain space at the top and bottom of the slide rail, which can facilitate the movement of other groups of fermentation boxes. This invention uses a first electric push rod to drive the mounting block to slide along the vertical groove. The bidirectional electric push rod, connecting frame, and toothed plate move upward, causing the drive gear to rotate and simultaneously contact the lower frame to lock the fermentation box and slide rail. After the toothed plate moves a certain distance, it separates from the drive gear. The first electric push rod continues to lift the connecting frame. Because the contact frame and connecting frame are pressed together, the second partition plate at the top of the second fermentation box and the fermentation box are pushed upward, thereby releasing the seal of the second partition plate on the top of the fermentation box. With the help of the internal structure of the mounting assembly, the fermentation box is pushed out, making it convenient for the detection probe on the moving plate to be inserted into the fermentation box. During this process, the fermentation box at any position can also be unlocked by manual operation, making it convenient to observe the fermentation situation inside the fermentation box. This invention drives the first screw to rotate via a drive motor. The moving plate moves along the moving groove in a threaded engagement with the first screw, corresponding to the lower frame at the top of each fermentation tank from top to bottom. When the moving plate initially moves, the connecting frame moves to both sides via a bidirectional electric push rod. At this time, the connecting frame can be moved from the position of the contact frame until the toothed plate corresponds to the position of the drive gear.

[0023] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown in the figure, this disclosure proposes an intelligent fermentation device for pickled vegetables, including: a cabinet 1, a door 14 rotatably mounted on the front of the cabinet 1, an air inlet device 11 fixed at the bottom of the cabinet 1, an installation assembly 3 inside the cabinet 1, fermentation chambers 4 equidistantly mounted inside the installation assembly 3, and a detection assembly 2 mounted on the inner surface of the door 14; the installation assembly 3 includes slide rails 31, there are four sets of slide rails 31, the four sets of slide rails 31 are fixed at the four corners inside the cabinet 1, and the slide rails Four sets of first partitions 32 are slidably fitted onto the top of the cabinet 1, and the fermentation box 4 is placed on the first partitions 32. The top of the fermentation box 4 is covered by a second partition 34, which is slidably fitted onto the slide rail 31. The bottom of both the first partitions 32 and the second partitions 34 are fixed with upper frames 37, and the bottom of the second partition 34 is fixed with a lower frame 36. The upper frames 37 and the lower frames 36 wrap around the back and sides of the fermentation box 4. The detection component 2 includes a moving groove 21, and the cabinet door 14... The inner surface of the device is provided with a moving groove 21, and a moving plate 24 is slidably connected inside the moving groove 21. A detection probe 211 is fixed on the surface of the moving plate 24. When using the device, the vegetables to be fermented are placed inside the fermentation box 4, the box door 14 is opened, the fermentation box 4 is placed on top of the first partition 32, and the top of the fermentation box 4 is sealed by the second partition 34. The temperature and humidity environment inside the box 1 is monitored by the temperature sensor and humidity sensor inside the box 1. The temperature and humidity inside the box 1 are maintained to suit the fermentation by the air inlet device 11 and the air outlet device 12. The installation component 3 is unlocked from the fermentation box 4 from top to bottom by the detection component 2 on the box door 14, and the top opening of the fermentation box 4 is pushed out. The detection component 2 inserts the detection probe 211 from the exposed opening of the fermentation box 4 to detect the number of anaerobic bacteria inside the fermentation box 4. The box door 14 is opened, and the connection between a certain layer of fermentation box 4 and the installation component 3 can be unlocked by the user to pull out the fermentation box 4 separately and check the fermentation status inside the fermentation box 4.
[0024] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the mounting assembly 3 further includes: a push plate 38, a spring 39, and a first sliding groove 310. The first sliding groove 310 is equidistantly provided on the top surface of the first partition 32. The push plate 38 is provided on the back of the upper frame 37. The bottom of the push plate 38 slides along the first sliding groove 310. A spring 39 is fixed inside the first sliding groove 310, and the other end of the spring 39 is fixedly connected to the push plate 38. Ventilation slots 35 are provided on both sides of the first partition 32 and the second partition 34. Horizontal slots 312 are provided on the sides of the upper frame 37 and the lower frame 36. A bidirectional screw 313 is rotatably mounted inside the horizontal slot 312. A friction plate 311 is threaded onto the surface of the bidirectional screw 313, and the friction plate 311 rubs against the surface of the slide rail 31. One end of the bidirectional screw 313 rotatably passes through the opening of the upper frame 37 and the lower frame 36. A transmission belt 314 is rotatably mounted on the middle position of the transverse groove 312 via a bearing bracket. One pulley of the transmission belt 314 is fixedly connected to a bidirectional screw 313, and a first bevel gear 318 is fixedly mounted on the pulley of the other side of the transmission belt 314. A second bevel gear 319 is meshed with one side of the first bevel gear 318, and a telescopic rod 320 is fixed at the axis of the second bevel gear 319. A stud 321 is fixed to the extended end of the telescopic rod 320. The stud 321 rotates through the transverse groove 312 and presses against the side of the fermentation tank 4. A second sliding groove 317 is provided on the top of both sides of the upper frame 37, and a slider 316 is slidably connected inside the second sliding groove 317. The slider 316 is fixedly connected to a push plate 38, and a connecting rod 315 is rotatably connected to the top of the slider 316 via a rotating shaft. The other end of the connecting rod 315 is rotatably connected to the bottom sides of the lower frame 36 via a rotating shaft.
[0025] Understandably, the fermentation box 4 is placed on the second partition 34, with the upper part sealed and covered by the first partition 32 and the second partition 34. Initially, the second partition 34, through the rotation of the bidirectional screw 313, causes the friction plate 311 to contact the slide rail 31, thereby stacking the fermentation boxes 4 inside the cabinet 1. There is also some space at the upper and lower ends of the slide rail 31, allowing for easy movement of other sets of fermentation boxes 4. When it is necessary to remove the fermentation box 4, the bidirectional screw 313 is rotated, driving the two friction plates 311 to move. Simultaneously, the transmission belt 314 drives the first bevel gear 318 to rotate and mesh with the second bevel gear 319, causing the telescopic rod 320 to rotate, allowing the stud 321 to rotate and pass through the transverse groove 312, thus realizing the rotation of the stud. The friction plate 311 and the stud 321 make extrusion contact with the side wall of the fermentation box 4. The locking methods of the friction plate 311 and the stud 321 are opposite, and there is an additional process in between. That is, the friction plate 311 does not contact the slide rail 31, and the stud 321 does not make extrusion contact with the fermentation box 4, so as to facilitate the delivery of the fermentation box 4. At the same time, when the lower frame 36 is pushed upward, the connecting rod 315 pulls the slider 316 to slide along the second slide groove 317, and the push plate 38 slides along the first slide groove 310. With the help of the spring 39 inside the first slide groove 310, the fermentation box 4 is pushed out. Here, it is not necessary to consider the fermentation box 4 being completely pushed out. Instead, with the box door 14 sealed, the unlocked fermentation box 4 is pushed out a small distance so that the detection probe 211 can be inserted.
[0026] like Figure 2 , Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, in some embodiments, the detection component 2 further includes: a first screw 22, a drive motor 23, a bidirectional electric push rod 28, and a connecting frame 29. The first screw 22 is rotatably mounted inside the moving slot 21, and the moving plate 24 is threaded onto the surface of the first screw 22. The top of the door 14 is fixed with the drive motor 23, and the output end of the drive motor 23 is fixedly connected to the first screw 22. The bidirectional electric push rod 28 is slidably mounted on the bottom surface of the moving plate 24. The extended end of the bidirectional electric push rod 28 is fixed with the connecting frame 29, and the two ends of the upper frame 37 facing the door 14 are fixed with contact frames 3. 3. The top of the contact frame 33 is pressed into contact with the top of the connecting frame 29. The end of the bidirectional screw 313 that passes through the lower frame 36 and the upper frame 37 is fixed with a drive gear 322. The connecting frame 29 is fixed with a toothed plate 210 on the side near the drive gear 322, and the toothed plate 210 is meshed with the drive gear 322. Vertical grooves 25 are opened on both sides of the moving plate 24, and mounting blocks 27 are slidably connected inside the vertical grooves 25. The bidirectional electric push rod 28 is fixed inside the mounting block 27. The first electric push rod 26 is fixed at the top of the moving plate 24 in the vertical groove 25, and the extended end of the first electric push rod 26 is fixedly connected to the mounting block 27.
[0027] Understandably, after the door 14 and cabinet 1 are combined, the drive motor 23 drives the first screw 22 to rotate. The moving plate 24, threadedly engaged with the first screw 22, moves along the moving groove 21, corresponding from top to bottom to the lower frame 36 of the top of each fermentation box 4. Initially, when the moving plate 24 moves, the connecting frame 29 moves to both sides via the bidirectional electric push rod 28. At this time, the connecting frame 29 can move from the position of the contact frame 33 until the toothed plate 210 corresponds to the position of the drive gear 322. For example, according to Figure 5 When the second-layer fermentation tank 4 needs to be sent out for testing, firstly, the toothed plate 210 moves to the position of the two drive gears 322 at the top of the second-layer fermentation tank 4. Then, the bidirectional electric push rod 28 drives the toothed plate 210 to contact the drive gears 322. At this time, the contact frames 33 on both sides of the second partition 34 at the top of the second-layer fermentation tank 4 contact the connecting frame 29. The first electric push rod 26 drives the mounting block 27 to slide along the vertical groove 25. The bidirectional electric push rod 28, the connecting frame 29, and the toothed plate 210 move upward, so that the drive gears 322 rotate and contact the lower frame 36 to lock the fermentation tank 4 and the slide rail 31. After the toothed plate 210 moves a certain distance, it separates from the drive gears 322, and the first electric push rod 26 continues to move. The lifting connecting frame 29 moves, and due to the squeezing contact between the contact frame 33 and the connecting frame 29, the second partition 34 on the top of the second fermentation box 4 and the fermentation box 4 are pushed upward, thereby releasing the seal of the second partition 34 on the top of the fermentation box 4. With the cooperation of the internal structure of the installation component 3, the fermentation box 4 is pushed out, making it convenient for the detection probe 211 on the moving plate 24 to be inserted into the fermentation box 4. During this process, the fermentation box 4 can also be unlocked at any position by direct manual operation, making it convenient to observe the fermentation situation inside the fermentation box 4. The detection method of the detection probe 211 involves the manufacture of medical diagnostic, monitoring and treatment equipment such as microbial detection and analysis instruments, diagnostic and screening systems, and microbial culture instruments in the prior art; and molecular biological information analysis and processing systems.
[0028] like Figure 2 As shown, in some embodiments, a temperature sensor and a humidity sensor are installed inside the cabinet 1, an air outlet device 12 is fixed on the top of the cabinet 1, the air inlet device 11 and the air outlet device 12 are connected to the inside of the cabinet 1, and a control panel 13 is fixedly installed on the side of the cabinet 1.
[0029] It should be noted that the air inlet device 11 is equipped with a cooling module and a heating module. The principle can be referred to as that of existing air conditioning technology. The internal environment of the cabinet 1 is monitored by temperature and humidity sensors inside the cabinet 1. The air inlet device 11 and the air outlet device 12 work together to realize the air flow inside the cabinet 1, thereby maintaining the cabinet 1 at a balanced temperature range suitable for the fermentation of pickles. The temperature and humidity inside the cabinet 1 can be monitored in real time through the control panel 13 on the outside of the cabinet 1. The detection component 2 can detect the number of anaerobic bacteria inside the fermentation box 4 and provide feedback, so as to facilitate timely detection and control of the situation inside the fermentation box 4.
[0030] Working principle: When using the device, place the vegetables to be fermented inside the fermentation box 4, open the box door 14, and place the fermentation box 4 on top of the first partition 32. The top of the fermentation box 4 is sealed by the second partition 34. The fermentation box 4 is placed on the second partition 34, with the upper layer sealed and covered by the first partition 32 and the second partition 34. Initially, the rotation of the bidirectional screw 313 causes the friction plate 311 to contact the slide rail 31, thereby stacking the fermentation boxes 4 inside the cabinet 1. The upper and lower ends of the slide rail 31 also have… A certain amount of space allows for easy movement of the other fermentation tanks 4. When fermentation tank 4 needs to be moved out, the bidirectional screw 313 is rotated, driving the two friction plates 311 to move. Simultaneously, the transmission belt 314 drives the first bevel gear 318 to rotate and mesh with the second bevel gear 319, driving the telescopic rod 320 to rotate. This causes the stud 321 to rotate and pass through the transverse groove 312, achieving a pressing contact between the stud 321 and the side wall of the fermentation tank 4. The locking methods of the friction plates 311 and the stud 321 are opposite, and there is an additional process in between. That is, the friction plate 311 does not contact the slide rail 31, and the stud 321 does not press against the fermentation box 4, thus facilitating the delivery of the fermentation box 4. At the same time, when the lower frame 36 is pushed upward, the connecting rod 315 pulls the slider 316 to slide along the second slide groove 317, and the push plate 38 slides along the first slide groove 310. With the help of the spring 39 inside the first slide groove 310, the fermentation box 4 is pushed out. Here, it is not necessary to consider the fermentation box 4 being completely pushed out, but rather to push out a small distance after the fermentation box 4 is unlocked while the box door 14 is sealed. The detection probe 211 can be inserted. After the door 14 and cabinet 1 are merged, the drive motor 23 drives the first screw 22 to rotate. The moving plate 24 and the first screw 22 are threaded together and move along the moving groove 21, corresponding from top to bottom to the lower frame 36 of the top of each fermentation box 4. When the moving plate 24 moves at the beginning, the connecting frame 29 moves to both sides through the bidirectional electric push rod 28. At this time, the connecting frame 29 can be moved from the position of the contact frame 33 until the toothed plate 210 corresponds to the position of the drive gear 322. For example, according to Figure 5When the second-layer fermentation tank 4 needs to be sent out for testing, firstly, the toothed plate 210 moves to the position of the two drive gears 322 at the top of the second-layer fermentation tank 4. Then, the bidirectional electric push rod 28 drives the toothed plate 210 to contact the drive gears 322. At this time, the contact frames 33 on both sides of the second partition 34 at the top of the second-layer fermentation tank 4 contact the connecting frame 29. The first electric push rod 26 drives the mounting block 27 to slide along the vertical groove 25. The bidirectional electric push rod 28, the connecting frame 29, and the toothed plate 210 move upward, so that the drive gears 322 rotate and contact the lower frame 36 to lock the fermentation tank 4 and the slide rail 31.
