Description

Technical Field

[0001] This utility model belongs to the field of brewing technology of yeast, and in particular relates to an automatic oxygen concentration regulating device for soy sauce-flavored yeast. Background Technology

[0002] In the field of brewing koji (fermentation starter), stacking fermentation is a core process that utilizes microbial metabolism to achieve saccharification and alcoholic fermentation of raw materials. During fermentation, oxygen concentration plays a decisive role in the growth and metabolism of microorganisms (such as molds and yeasts) and the generation of flavor compounds, requiring precise control through aeration equipment. Currently, traditional aeration equipment mostly uses a single vent in a single pipe to inject oxygen into the stacked koji. While this method is simple in structure and low in cost, it has significant drawbacks in practical applications.

[0003] Because of pressure loss along the flow path of gas within the pipeline, the gas flow rate is uneven when exiting through vents at different locations. Vents closer to the gas inlet have higher pressure and larger gas discharge, while vents farther from the inlet have significantly lower discharge due to pressure attenuation. This uneven oxygen supply causes an imbalance in the oxygen concentration distribution within the yeast starter buildup. Excess oxygen in some areas leads to the proliferation of aerobic bacteria and excessive oxidation of flavor substances, while insufficient oxygen in other areas inhibits the normal metabolism of beneficial microorganisms such as yeast and mold, reduces enzyme activity, and slows down the fermentation process. Ultimately, this results in fluctuations in key indicators such as saccharification and liquefaction power of the yeast starter, leading to uneven quality of the finished yeast starter and seriously affecting the flavor consistency and production stability of alcoholic beverages. For example, the above-mentioned problem exists in patent number CN202223056632.9, resulting in uneven oxygen supply during equipment operation and inconvenient adjustment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an automatic oxygen concentration adjustment device for soy sauce-flavored liquor yeast, which solves the problem of uneven oxygen supply when adjusting existing equipment.

[0005] This utility model is implemented as follows: an automatic oxygen concentration regulating device for soy sauce-flavored liquor yeast, applied in a fermentation chamber, includes a hollow tube that is rotatably installed in the fermentation chamber, an oxygen supply machine installed on the fermentation chamber and communicating with the hollow tube, a rotating plate is provided at the connection between the hollow tube and the oxygen supply machine, and also includes;

[0006] A convex tube is formed on a hollow tube for the gas to be discharged from the hollow tube, and a T-shaped sealing block is movably installed in each convex tube for sealing the convex tube. The sealing block has an H-shaped vent hole for gas to flow out.

[0007] A drive unit, mounted on a hollow tube, is used to drive the rotation of the hollow tube and the movement of the sealing blocks. It includes cams mounted inside the hollow tube for driving the movement of the sealing blocks, and the number of cams is the same as the number of sealing blocks. The cams intermittently drive multiple sealing blocks to move.

[0008] In a preferred embodiment of this invention, multiple horizontal tubes are vertically arranged on the hollow tube, and the horizontal tubes are interconnected with the hollow tube. The convex tubes are arranged in a straight line on the horizontal tubes and hollow tube.

[0009] As a preferred embodiment of this invention, each cam is in active contact with the sealing block, and the cam protrusions are arranged in a spiral shape around the axis of the horizontal tube.

[0010] As a preferred embodiment of this invention, a spring for resetting is fixedly provided on the sealing block.

[0011] As a preferred embodiment of this utility model, the drive unit includes a transmission rod rotatably disposed inside a horizontal tube for mounting multiple cams, and a drive rod that meshes with the transmission rod is rotatably disposed inside the hollow tube.

[0012] As a preferred embodiment of this utility model, the drive unit further includes a toothed ring installed on the outside of the hollow tube, and a gear rotatably mounted on the fermentation box and meshing with the toothed ring. A drive motor is installed on the fermentation box, and the output end of the drive motor is respectively connected to the drive rod and the gear transmission.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a drive unit within the device to effectively drive the hollow tube to rotate. When the hollow tube rotates, the horizontal tube on it can be effectively inserted into the yeast. Simultaneously, as the hollow tube rotates, the convex tubes are intermittently opened, ensuring that the gas inside each convex tube is evenly injected into the yeast when it opens. This avoids the problem of uneven airflow caused by directly opening multiple holes on the horizontal tube, which would result in uneven oxygen supply. This further improves the uniformity and convenience of oxygen supply. Furthermore, the movement of the sealing block within the convex tube each time prevents blockage and prevents yeast from entering the hollow tube, thus affecting its subsequent use.

[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown in the figure, the present invention provides an automatic oxygen concentration adjustment device for a type of soy sauce-flavored liquor yeast, which is applied in a fermentation chamber 1. It includes a hollow tube 2 that is rotatably installed in the fermentation chamber 1, an oxygen supply machine 3 that is installed on the fermentation chamber 1 and communicates with the hollow tube 2, and a rotating plate 11 is provided at the connection between the hollow tube 2 and the oxygen supply machine 3.

[0024] A convex tube 4 is formed on the hollow tube 2 for the gas to be discharged from the hollow tube 2, and a T-shaped sealing block 5 is movably installed in each convex tube 4 for sealing the convex tube 4. An H-shaped vent 6 for gas to flow out is formed on the sealing block 5.

[0025] The drive unit, which is installed on the hollow tube 2, is used to drive the rotation of the hollow tube 2 and the movement of the sealing block 5. It includes cams 8 installed inside the hollow tube 2 for driving the movement of the sealing block 5. The number of cams 8 is the same as the number of sealing blocks 5. The cams 8 intermittently drive multiple sealing blocks 5 to move.

[0026] As a preferred embodiment of this utility model, multiple horizontal tubes are vertically arranged on the hollow tube 2, and the horizontal tubes are interconnected with the hollow tube 2. The convex tubes 4 are arranged in a straight line on the horizontal tubes of the hollow tube 2, which facilitates the extraction of air from the hollow tube 2 and its flow into the yeast, thus ensuring the oxygen supply inside.

[0027] As a preferred embodiment of this utility model, each cam 8 is in active contact with the sealing block 5, and the protrusions of the cam 8 are arranged in a spiral shape around the axis of the horizontal tube, which can effectively enable multiple sealing blocks 5 to open intermittently, thereby preventing uneven air output from the vent.

[0028] As a preferred embodiment of this utility model, a spring 7 for resetting is fixedly provided on the sealing block 5, which facilitates the rebound of the sealing block 5 and thus facilitates the sealing of the convex tube 4.

[0029] As a preferred embodiment of this utility model, the drive unit includes a transmission rod 9 rotatably disposed inside the horizontal tube for mounting multiple cams 8, and a drive rod 10 rotatably disposed inside the hollow tube 2 that meshes with the transmission rod 9, so as to facilitate the simultaneous driving of multiple sealing blocks 5 to work, while ensuring the intermittent opening of the convex tube 4.

[0030] As a preferred embodiment of this utility model, the drive unit further includes a toothed ring 12 installed on the outside of the hollow tube 2, and a gear 14 rotatably mounted on the fermentation box 1 and meshing with the toothed ring 12. A drive motor 13 is installed on the fermentation box 1, and the output end of the drive motor 13 is connected to the drive rod 10 and the gear 14 respectively, so that oxygen can be fully injected into the yeast when the equipment is working.

[0031] The working principle of this utility model:

[0032] refer to Figure 1 The yeast is placed in fermentation box 1 for fermentation. Both fermentation box 1 and hollow tube 2 are equipped with oxygen supply detectors. The data from the detectors ensures the oxygen supply in fermentation box 1. When oxygen supply machine 3 is working, the following operations can be performed.

[0033] refer to Figure 2 and 3 In its initial state, the sealing block 5 seals the convex tube 4, making the inside of the hollow tube 2 sealed. At this time, the oxygen supply machine 3 fills the hollow tube 2 with gas, so that the gas in the hollow tube 2 fills each horizontal tube, keeping the gas in the hollow tube 2 balanced. When the drive motor 13 works, the drive motor 13 drives the gear ring 12 to rotate through the gear 14, thereby driving the hollow tube 2 to rotate. At the same time, the drive motor 13 drives the drive rod 10 to rotate. When the gear ring 12 rotates, the hollow tube 2 rotates in the fermentation box 1, so that multiple horizontal tubes can be inserted into the yeast, and the yeast is stirred at the same time.

[0034] refer to Figure 3 With the convex tube 4, when the drive rod 10 rotates, the drive rod 10 drives multiple transmission rods 9 to rotate. When the transmission rods 9 rotate, since the convex points of the cam 8 are arranged in a spiral shape on the transmission rods 9, the contact time between the convex points on the cam 8 and the sealing block 5 is intermittent. Therefore, the cam 8 will gradually push multiple sealing blocks 5 to slide inside the convex tube 4. When the sealing block 5 extends out of the convex tube 4, the gas is discharged from the convex tube 4 through the air hole 6, and can then enter the yeast. When the sealing block 5 descends, the sealing block 5 will squeeze the spring 7 to compress it. When the convex points on the cam 8 move away from the sealing block 5, the elastic force of the spring 7 will reset the sealing block 5. The next cam 8 will then squeeze the next sealing block 5 to repeat the above work, thereby realizing that multiple convex tubes 4 are in an intermittent open state, so that oxygen is evenly filled into the yeast.

[0035] This invention effectively drives the hollow tube 2 to rotate through the drive unit in the device. When the hollow tube 2 rotates, the horizontal tube on the hollow tube 2 can be effectively inserted into the yeast. At the same time, when the hollow tube 2 rotates, the convex tube 4 will be opened intermittently, and one convex tube 4 will be opened at a time. This ensures that the gas inside each convex tube 4 can be evenly filled into the yeast when it is opened, avoiding the situation where multiple holes are directly opened on the horizontal tube, which would lead to uneven airflow and uneven oxygen supply. This further improves the uniformity and convenience of oxygen supply. The movement of the sealing block 5 inside the convex tube 4 can also prevent the convex tube 4 from being blocked and prevent the yeast from entering the hollow tube 2, thus affecting its subsequent use.
