Description

Technical Field

[0001] This utility model relates to a fermentation device, and more particularly to a fermentation device for fermentation, transfer and feeding of baijiu (Chinese liquor) in fermentation pits, belonging to the field of baijiu production technology. Background Technology

[0002] Baijiu, or Chinese liquor, is a distilled spirit made primarily from grains, using daqu (large koji), xiaoqu (small koji), bran koji, enzymes, and yeast as saccharification and fermentation agents. The process involves cooking, saccharification, fermentation, distillation, aging, and blending. The production process of baijiu varies depending on its aroma type (such as strong aroma, sauce aroma, light aroma, and rice aroma) and the specific techniques used. The basic process of traditional solid-state fermented baijiu mainly includes: raw material processing → fermentation → distillation → aging → blending → finished product.

[0003] In baijiu production, "removing the mash" (also known as "leaving the cellar" or "digging out the mash") refers to the process of taking / extracting the fermented mash (lees) from the fermentation pit in preparation for distillation. It is one of the key steps in the traditional solid-state fermentation process of baijiu (such as strong-aroma, sauce-aroma, and light-aroma types), directly affecting the yield and quality of the liquor.

[0004] Currently, the traditional liquor brewing industry faces challenges such as rising labor costs, insufficient process standardization, high labor intensity in manual fermentation, and the danger of working in confined spaces like fermentation pits, which can easily lead to poisoning from toxic gases such as carbon dioxide and hydrogen sulfide. Therefore, there is an urgent need to use automated equipment (such as fermentation equipment) to achieve efficient and precise operation in processes such as fermentation extraction and fermentation pit cleaning.

[0005] Although existing technologies such as CN111117823A ("An Automatic Fermentation Equipment"), CN212292020U ("An Eating Equipment"), and CN213230200U ("A Layered Fermentation Mechanism for Fermentation Pit") only achieve the raising or feeding of lees into the still, they cannot effectively connect the subsequent transportation and / or feeding of lees. This results in a low degree of automation between the lees raising, transportation, and feeding processes, which on the one hand cannot guarantee the continuity of the production process, and on the other hand leads to low production efficiency.

[0006] Therefore, a slobbing device that can reduce manual labor, is highly safe, and has a high degree of automation (capable of slobbing, transferring, and feeding) is needed. Summary of the Invention

[0007] To address the problems of existing fermentation equipment's inability to effectively connect with subsequent fermentation and / or steaming processes, resulting in low automation levels between fermentation, transfer, and feeding steps, thus compromising production continuity and leading to low production efficiency, a new fermentation device for fermentation, transfer, and feeding in baijiu (Chinese liquor) fermentation pits is proposed. This technical solution, through the setup of fermentation, transfer, and feeding units, achieves automated fermentation, transfer, and feeding, ensuring better stability and safety in pit operation; simultaneously, it significantly reduces labor intensity and improves production efficiency.

[0041] The slag-lifting unit 2 includes a slag-lifting arm I 20, a slag-lifting arm II 21, a drive cylinder I 22, and a drive cylinder II 23. The slag-lifting arm I 20 is inclined, with its lower end extending downward and its upper end extending towards the slag-lifting arm II 21. The slag-lifting arm II 21 is horizontally positioned, with one end movably connected to the slag-lifting arm I 20 (e.g., the slag-lifting arm I 20 and the slag-lifting arm II 21 are connected via a gear 28), and the other end extending towards the slag-transporting unit 3. One end of the drive cylinder I 22 is connected to the slag-lifting arm I 20, and the other end is connected to the slag-lifting arm II 21. One end of the drive cylinder II 23 is connected to the slag-lifting arm II 21, and the other end is connected to the slag-transporting unit 3.

[0042] A ring conveyor belt I24 is provided on the outer side of the fermentation arm I20, and a ring conveyor belt II25 is provided on the outer side of the fermentation arm II21. The ring conveyor belts I24 and II25 are connected (because a gear 28 is provided between the fermentation arm I20 and the fermentation arm II21, during the conveying of the digging bucket 26, when the digging bucket 26 is conveyed on the ring conveyor belt I24 to the rightmost side of the fermentation arm I20, the gear 28 transfers the digging bucket 26 from the ring conveyor belt I24 to the ring conveyor belt II25, and then conveys it to the discharge port on the right side of the fermentation arm II21), and the two form a continuous fermentation conveying route; digging buckets 26 are distributed on both the ring conveyor belts I24 and II25 (e.g., Figure 4 As shown), the scoop bucket 26 moves in a loop along the lees conveying route;

[0043] The lees transport unit 3 includes a hopper 30 mounted on the rotating mechanism 14. The inlet of the hopper 30 is located directly below the outlet of the lees lifting arm II 21 (during lees transport); the hopper 30 has an outlet at its lower part.

[0044] Feeding unit 4: includes a clamping mechanism located on one side of the hopper 30 (such as... Figure 5 As shown), the clamping mechanism includes a lifting cylinder 40 and a material-retrieving clamp 41 located at the lower end of the lifting cylinder 40.

[0045] The system, through the setup of the slag-raising unit 2, the slag-transporting unit 3, and the feeding unit 4, achieves automated slag-raising, slag-transporting, and slag-feeding, ensuring good stability and safety in the operation of the fermentation pit; at the same time, it can significantly reduce labor intensity and improve production efficiency.

[0046] Example 2

[0047] Based on Embodiment 1, this embodiment further defines the slagging unit 2 to further illustrate the technical solution.

[0048] like Figure 2 As shown, in the slag-raising unit 2, there are at least two slag-raising buckets 26, which are evenly distributed on the annular conveyor belt I 24 and the annular conveyor belt II 25, which can ensure the orderliness and continuity of the slag-raising process.

[0049] In addition, a vision sensor 27 is provided at the lower end of the lees raising arm I 20. The vision sensor 27 is connected to the electrical control system 5 via an electrical signal. The vision sensor 27 is used to detect the remaining amount of lees in the lees raising area.

[0050] Example 3

[0051] Based on embodiments 1-2, this embodiment further defines the transport unit 3 to further illustrate the technical solution.

[0052] In the conveying unit 3, the upper part of the hopper 30 is provided with a feeding level device 31 for detecting whether the hopper 30 is full, and the lower part of the hopper 30 is provided with a discharging level device 32 for detecting whether the hopper 30 is short of material.

[0053] The installation of the feed level controller 31 and the discharge level controller 32 ensures real-time monitoring of the amount of distiller's grains stored in the silo 30, thereby facilitating adjustments to the distiller's grains raising and feeding processes. For example, when the feed level controller 31 detects that the silo 30 is full, the electrical control system 5 controls the distiller's grains raising unit 2 to stop raising the grains; simultaneously, the electrical control system 5 controls the feeding unit 4 to feed the grains, and so on.

[0054] Example 4

[0055] Based on embodiments 1-3, this embodiment further specifies the following for better installation and arrangement of the components in this device:

[0056] The rotating mechanism 14 is equipped with a mounting bracket 15, and the slag-lifting arm II 21 is mounted on the mounting bracket 15. This arrangement can better install and fix the slag-lifting arm II 21, thereby ensuring that the slag-lifting arm I 20 and the slag-lifting arm II 21 can lift slag stably;

[0057] The mounting bracket 15 is set on the outside of the hopper 30. This setting can save space and at the same time ensure that the feed inlet of the hopper 30 is located directly below the discharge outlet of the lees lifting arm II 21, thus realizing the stable and effective transfer and temporary storage of the lees after lees lifting.

[0058] The clamping mechanism is mounted on the mounting frame 15. More specifically, one end of the lifting cylinder 40 is fixed on the mounting frame 15, and the other end is connected to the material handling clamp 41.

[0059] Example 5

[0060] Based on embodiments 1-4, this embodiment further defines the following to better achieve automation and controllability, and to ensure the effectiveness of the corresponding actions in this device:

[0061] like Figure 6 As shown, the rotating mechanism 14 is connected to drive motor I 16, the linear guide rail 12 is connected to drive motor II 17, the roller group 13 is connected to drive motor III 18, the annular conveyor belt I 24 is connected to drive motor IV 19, and the annular conveyor belt II 25 is connected to drive motor V 100.

[0062] Drive cylinder I 22, drive cylinder II 23, drive cylinder III 42, lifting cylinder 40, drive motor I 16, drive motor II 17, drive motor III 18, drive motor IV 19 and drive motor V 100 are all connected to the electrical control system 5 via electrical signals.

[0063] Example 6

[0064] Based on Examples 1-5, this example provides: a method for removing, transferring, and feeding lees into a liquor fermentation pit, involving the following workflow:

[0065] 1. Inspect the main body of the mobile trolley 1, linear guide rail 12, rotating mechanism 14, circular conveyor belt I 24, circular conveyor belt II 25, trough lifting arm I 20, trough lifting arm II 21, roller group 13, and electrical control system 5, etc.

[0066] According to the production order, this lees-raising device uses the roller group 13 to drive the moving trolley 1 to the corresponding fermentation pit; after reaching the designated position, the rotating mechanism 14 turns the lees-raising arm I 20 and lees-raising arm II 21 to the corresponding fermentation pit; by controlling the extension of the drive cylinder I 22 and drive cylinder II 23, the lees-raising arm I 20 and lees-raising arm II 21 are unfolded respectively, and the ring conveyor belt I 24 and ring conveyor belt II 25 drive the lees-raising bucket 26 to raise the lees and convey the lees to the silo 30;

[0067] When the vision sensor 27 on the lees lifting arm I20 detects that the amount of lees remaining in the area of ​​the cellar is 0, the position of the lees lifting arm I20 and the lees lifting arm II21 is adjusted by using the linear guide rail 12 and the rotating mechanism 14.

[0068] Thus, through the continuous lees-raising operation of the lees-raising unit 2, the lees enter the silo 30 and are then transferred to the feeding pit. The silo 30 is equipped with full and low material detection sensors (upper material level sensor 31 and lower material level sensor 32) to control the working cycle: when the upper material level sensor 31 is ON, the lees-raising unit 2 stops working, the electrical control system 5 controls the material-retrieving clamp 41 in the feeding unit 4 to release, the moving trolley 1 waits for 2 seconds, leaves the pit, and uses the roller group 13 to go to the feeding and stirring point for feeding;

[0069] 2. Inspect the main body of the mobile trolley 1, the hopper 30, the discharge port, the linear guide rail 12, the rotating mechanism 14, and the electrical control system 5, etc.

[0070] When the silo 30 is full of lees, the production system issues a command to move the trolley 1 to the designated fermentation pit. Upon arrival at the pit, the small rotating mechanism 14 rotates outward. The clamping mechanism picks up the lees and places them onto the lees-lifting arm II 21. Simultaneously, the lees-lifting arm I 20 and lees-lifting arm II 21 reverse their directions (i.e., the circular conveyor belt I 24 and the circular conveyor belt II 25 move in opposite directions), thus feeding the lees into the fermentation pit. The amount of lees fed is detected by the vision sensor 27 on the lees-lifting arm I 20. Through the movement of the linear guide rail 12 and the rotating mechanism 14, lees are fed into different areas within the fermentation pit. When the material level sensor 32 detects a shortage, it issues a shortage command, and the trolley 1 returns to the picking point to pick up lees.

[0071] Among them, the lifting cylinder 40 drives the material handling clamp 41 to move up and down, specifically including: moving the lees in the silo 30 to the feed inlet of the lees lifting arm II 21 through the material handling clamp 41, and then unloading the lees; the drive cylinder III 42 drives the material handling clamp 41 to clamp and release the lees.

[0072] When the current material level sensor 32 is ON, the feeding unit 4 stops feeding after a 2-second delay; the drive roller group 13 returns to the pit again to start the slag-lifting machine again. The electrical control system 5 controls the material-retrieving clamp 41 in the feeding unit 4 to clamp, and the slag-lifting unit 2 continues the slag-lifting work until the production instruction is completed.
