Description

Technical Field

[0001] This invention relates to the field of fermentation technology for sauces and condiments, specifically to an automated fermentation device for the production of broad bean paste. Background Technology

[0002] Fermentation of fermented soybeans is the core process in fermentation. During fermentation, the composition, flavor, and quality of the fermented soybeans dynamically change with time and spatial distribution. Timely monitoring of the quality of the fermented soybeans is crucial to ensuring the stability of the final product quality. Automated fermentation equipment for fermented soybean production, as the core equipment for achieving large-scale and standardized production, must possess relevant functions adapted for quality monitoring during the fermentation process. By sampling and testing soybeans at different stages and locations during fermentation, data support is provided for optimizing and adjusting the fermentation process.

[0003] In existing automated fermentation equipment for fermented soybean paste production, corresponding sampling components are typically configured to collect and test soybean paste samples during the fermentation process. These sampling components are usually mounted on the stirring mechanism of the fermentation equipment via a fixed connection structure. Their structure generally includes a mounting frame, a sampling box, and connecting bolts. The working principle is that the sampling box is fixed to the mounting frame using the connecting bolts, and the mounting frame is then connected to the stirring mechanism. The rotation of the stirring mechanism drives the sampling box to rotate synchronously, thereby scooping up soybean paste samples from the fermentation chamber and completing the sampling operation.

[0004] In existing technologies, the connection between the sampling component and the stirring mechanism lacks a flexible and adjustable structural design. This results in a relatively fixed installation position for the sampling component, making it impossible to adjust the sampling height and distribution position according to the actual fermentation process of the fermented soybeans. Consequently, it is difficult to achieve comprehensive sampling and testing of soybeans from different layers within the fermentation chamber. Furthermore, the fixing structure of the sampling component lacks a reliable clamping and positioning mechanism. During the high-speed rotation of the stirring mechanism, the sampling component is prone to loosening and displacement, affecting the stability of the sampling process and consequently impacting the accuracy of the test data. This fails to meet the requirements for flexibility, convenience, and reliability in soybean production. Therefore, we propose an automated fermentation device for soybean production. Summary of the Invention

[0005] One of the technical problems to be solved by this application is that the connection between the sampling component and the stirring mechanism in the existing structure lacks a flexible and adjustable structural design, which results in the installation position of the sampling component being relatively fixed.

[0011] In some embodiments, the matching block is disposed on the horizontally proximal side of the plurality of sampling leaves, the support leaf and the plurality of sampling leaves correspond one-to-one, and the sampling leaf is slidably connected to the top of the support leaf.

[0012] In some embodiments, one of the plurality of sealing plates abuts against the distal side of the plurality of sampling blades, one end of the two springs away from the sampling blades is disposed on the outer side of the baffle, and sealing strips are embedded in the two end faces of the two baffles that are in contact with the inner wall of the slot.

[0015] In some embodiments, the second support rod is disposed at the bottom end of the first support rod, the ends of the plurality of telescopic airbags are disposed on the horizontally proximal side surfaces of the plurality of telescopic rods, and the two air pumps are disposed at the inner top of the mixing tank body.

[0016] The present invention has at least the following beneficial effects: 1. By installing multiple movable sampling components into the slot in an upper, middle, and lower distribution, the connecting block is manually aligned with the positioning slot and slid to engage the first and second locking blocks, simultaneously closing the sealing plate. The outer matching block of the sampling blade engages with the installation slot block to complete the installation and fixation of the sampling blade. The limiting block on the surface of the inner baffle of the slot slides along the groove of the movable sampling component, and the spherical block is inserted into the fixing slot, driving the spring to generate a relative compressive force, thereby enabling the movable sampling component to achieve positioning and fixation. This ensures accurate installation and positioning of the movable sampling component, secure fixation, and prevents loosening, guaranteeing the stability and firmness of the sampling and collection process. At the same time, the distribution position of the three movable sampling components can be flexibly adjusted according to the overall quality of the fermented soybean paste to ensure that comprehensive sampling of the upper, middle, and lower layers of the fermented soybean paste can always be carried out, improving the accuracy and representativeness of the sampling results.

[0017] 2. The battery box drives the electric push rod to slide the linkage plate. The inclined groove drives the synchronous block to extend and retract along the limiting shell. The second locking block engages with the first locking block, which drives the connecting rod to make the two sealing plates open and close vertically. At the same time, the guide plate rotates synchronously, and the air pump delivers air to the air inlet hood. The sealing ring seals the air inlet hood and the main shaft. The gas enters the three-head air delivery pipe through the air inlet hole and is delivered to the telescopic air bag. The telescopic air bag inflates and expands, which drives the telescopic rod to slide along the second support rod. This structure drives the sampling blade to extend and retract, and the fermented soybean paste to flow radially. This achieves battery-driven operation without external wiring, avoiding wire entanglement during stirring. The vertical opening and closing of the sealing plate accurately collects a certain layer of fermented soybean paste and prevents excess fermented soybean paste from flowing into the sampling box to ensure the detection effect. The guide plate promotes the radial flow of fermented soybean paste and improves stirring efficiency. The sampling blade adheres to the inner wall of the stirring tank to improve collection and stirring efficiency. The air inlet hood and air pump remain stationary to further avoid the risk of external wire entanglement. Attached Figure Description

[0028] Based on the above embodiments, the following is the complete working principle of the above embodiments: When it is necessary to sample the fermented soybean paste, multiple movable sampling components 3 are distributed in an upper, middle and lower manner and sequentially placed into multiple slots 2 for installation. The connecting block 306 is manually aligned with the positioning slot 17 and slid inward. It is manually engaged by the first locking block 307 and the second locking block 16. At this time, the two sealing plates 302 are in a closed state. The multiple sampling blades 1 can be installed and fixed by sliding the matching block 31 set on the outside of the sampling blade 1 into the installation slot block 30. The slot 2 is set with The limiting blocks 5 set on the surface of the two baffles 4 slide on the inner wall of the slide groove 308 to position the installation of the movable sampling component 3. The two spherical blocks 6 are engaged in the inner wall of the fixed groove 309. The movable sampling component 3 is fixed by the relative squeezing force of multiple springs 7. Conversely, the movable sampling component 3 will loosen during the sampling process, ensuring the stability and firmness of the collection process. At the same time, the distribution position of the three movable sampling components 3 can be adjusted according to the overall quality of the fermented soybean paste, and determined relative to the quality of the fermented soybean paste, to ensure that the upper, middle and lower layers can always be sampled. When rotational sampling is required, the battery box 9 is activated. The battery box 9 is battery-driven and does not require external wiring to prevent wiring from tangling during stirring. The battery box 9 drives the linkage plate 11 to slide synchronously through the electric push rod 10. The inclined groove 12 slides and drives multiple synchronous blocks 14 to extend and retract. The limiting shell 13 ensures the sliding trajectory of the synchronous blocks 14. Since the second locking block 16 is engaged with the first locking block 307, it pushes outward to abut against the connecting block 306 to drive the sealing plate 302 of the active sampling component 3 to unfold and sample the fermented bean paste. At the same time, the two sealing plates 302 open and close vertically, which can accurately collect a certain layer of fermented bean paste while preventing excess fermented bean paste from flowing into the sampling box 301, ensuring the detection effect. After collection, the battery box 9 is controlled to reverse and drive the electric push rod 10 to retract. The inclined groove 12 in the linkage plate 11 drives the second locking block 16 to pull the first locking block 307 backward to drive the sealing plate 302 of the active sampling component 3 to close. Multiple guide plates 18 rotate synchronously, enabling the fermented soybean paste to flow radially and improving stirring efficiency. Two air pumps 23 are located at the top inside the mixing tank body 33 to supply gas into the air inlet hood 21. The sealing ring 22 forms a sealed environment between the air inlet hood 21 and the main shaft 19, ensuring that the gas can be delivered through the air inlet 20 into multiple three-headed air supply pipes 25. The gas is then delivered into the telescopic air bladder 28 through the two air outlets of the three-headed air supply pipes 25. The telescopic air bladder 28 inflates and expands synchronously, driving the telescopic rod 29 to slide in the support rod 27, which synchronously extends and retracts multiple sampling blades 1, making the sampling blades 1 fit more closely to the inner wall, improving collection and stirring efficiency. At the same time, since the air inlet hood 21 and the two air pumps 23 are stationary, the risk of tangling external wiring is avoided.
