Description

Technical Field

[0001] This invention belongs to the field of liquor fermentation technology, specifically a liquor fermentation equipment and fermentation process. Background Technology

[0002] Baijiu is a unique distilled spirit from China and one of the world's eight major distilled spirits. It is made by distilling fermented starch or sugary raw materials. It is also known as shaojiu, laobaigan, shaodaozi, etc., and was officially called baijiu after the founding of the People's Republic of China.

[0003] Although my country's baijiu (white liquor) fermentation technology originated from huangjiu (yellow wine), compared to the history of huangjiu, baijiu production technology is still far from perfect. Therefore, modern research has extensively explored baijiu fermentation processes. In the 1950s and 60s, the most influential reform was the comprehensive summary of the "Yantai Operation Method." This method borrowed two key technologies from the alcohol industry: bran koji and yeast starter production, and combined them with traditional baijiu techniques to form a relatively standardized operating procedure. Its characteristics were summarized at the time as: "Bran koji and yeast starter, reasonable ingredient formulation, low-temperature fermentation, and constant-temperature distillation."

[0004] In the process of fermenting baijiu, the fermentation tank is an indispensable part. After the raw materials have finished fermenting, the raw materials in the fermentation tank need to be transferred and the fermentation tank needs to be cleaned. Since most fermentation tanks are rectangular, the tank body will be obstructed when cleaning the fermentation tank, and it is more troublesome to clean the bottom of the fermentation tank. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology and solve the above-mentioned technical problems, this invention proposes a liquor fermentation equipment and fermentation process.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides a liquor fermentation device, which includes a fermentation tank; the fermentation tank is partially located in the soil layer, and the soil layer is built on the ground.

[0007] The fermentation tank has uniformly arranged baffles fixed to its inner surface; a bottom plate is provided above the baffles and is in contact with the inner surface of the fermentation tank.

[0008] Two connecting rods are fixedly connected to the upper surface of the base plate at both sides of the base plate; a mounting plate is fixedly connected to the top of each of the two adjacent connecting rods; and steel cables are fixedly connected to the upper surface of each of the two mounting plates.

[0009] The fermentation tank is equipped with mounting frames on both sides of the soil layer, and a winch is installed on the top of each mounting frame. The other side of the steel cable fixed on the mounting plate is connected to the winch.

[0010] Below the base plate, inside the fermentation tank, there are evenly arranged liquid outlet pipes, all of which extend through the soil layer to the outside; each of the liquid outlet pipes is equipped with a valve.

[0011] Optionally, a filter layer is provided below the base plate, and the filter layer is made of filter cloth;

[0012] The filter layer is initially in a relaxed state;

[0013] The baffle is fixedly connected to a mounting block on one side of its opposite end face, and each mounting block has a mounting groove. The filter layer is fixedly connected to an insert plate on the side near the mounting block, and the insert plate is inserted into the mounting groove.

[0014] Optionally, two floats are provided below the baffle at the bottom of the fermentation tank; the lower surface of the floats is fixed with evenly arranged pull ropes, and the other side of each pull rope is connected to the bottom of the fermentation tank.

[0015] Optionally, two of the floats are rotatably connected to a rotating rod on opposite sides of the inner wall of the fermentation tank, and part of the rotating rod extends into the liquid outlet pipe; uniformly arranged rotating blades are fixed to the outer surface of the rotating rod, and part of the rotating blades are placed inside the liquid outlet pipe; the rotating rod is driven by a driving device, which is a motor.

[0016] The outer surface of the blade is covered with a rubber layer.

[0017] A baijiu (Chinese liquor) fermentation process, applicable to the aforementioned baijiu fermentation equipment; the process steps are as follows:

[0018] S1: First, put the raw materials to be fermented into the fermentation tank and control the temperature of the raw materials to be between 18-20℃ (not exceeding 26℃ in summer);

[0019] S2: The raw materials added to the fermentation tank should not be too tightly packed or too loosely packed. Generally, it is advisable to pack about 630-640 kg of chaff per cubic meter of volume. After packing, cover the raw materials with a layer of chaff, seal with pit mud, and then add another layer of chaff.

[0020] S3: Real-time analysis and monitoring of changes in moisture, acidity, alcohol content, and starch residue in raw materials. Fermentation can be terminated when the temperature in the fermentation tank rises to 36-37℃.

[0021] After S4 fermentation is complete, the raw materials are removed from the fermentation tank.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The fermentation equipment and process for baijiu (Chinese liquor) described in this invention, during the upward movement of the bottom plate, will push the remaining raw materials upward. During the upward movement of the raw materials, the workers can remove the raw materials that move with the bottom plate. At the same time, during the upward movement of the bottom plate, the raw materials adhering to the side wall of the fermentation tank can also be pushed upward, thereby simply cleaning the side wall of the fermentation tank. When the bottom plate moves to be level with the top of the fermentation tank, the winch is stopped. At this time, the workers can remove the raw materials on the surface of the bottom plate. In this process, there is no obstruction from the body of the fermentation tank, so the raw materials in the fermentation tank can be cleaned out more easily.

[0024] 2. The fermentation equipment and process for baijiu (Chinese liquor) described in this invention allows the bottom plate to move within the fermentation tank via a winch. During the movement of the bottom plate, the height of the bottom plate to the top of the fermentation tank is adjusted, thereby regulating the capacity of the fermentation tank. When more or less raw material needs to be fermented, the movement of the bottom plate within the fermentation tank can be controlled to adjust the capacity of the fermentation tank, thus adapting to the amount of raw material to be fermented.

[0025] 3. The fermentation equipment and process for baijiu (Chinese liquor) described in this invention, since a filter layer is provided below the bottom plate, the liquid flowing down from the gap between the bottom plate and the fermentation tank will first fall onto the filter layer. Since the filter layer is made of filter cloth, the liquid flowing through the filter layer will pass through the filter layer, and the raw materials mixed in the liquid will be filtered onto the filter layer. In this process, the raw materials can be separated from the liquid. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1 to 6 As shown, the fermentation equipment and process for baijiu (Chinese liquor) of the present invention are as follows:

[0037] A baijiu (Chinese liquor) fermentation equipment includes a fermentation tank 1; the fermentation tank 1 is partially located within a soil layer 11, and the soil layer 11 is built on the ground.

[0038] The fermentation tank 1 has uniformly arranged baffles 12 fixedly connected to its inner surface; a bottom plate 13 is provided above the baffles 12 and the bottom plate 13 is in contact with the inner surface of the fermentation tank 1.

[0039] Two connecting rods 14 are fixedly connected to the upper surface of the base plate 13 on both sides of the base plate 13; the top of each of the two adjacent connecting rods 14 is fixedly connected to a mounting plate 15; and steel cables 16 are fixedly connected to the upper surfaces of the two mounting plates 15.

[0040] Both sides of the fermentation tank 1 are equipped with mounting frames 17 on the soil layer 11, and a winch 18 is installed on the top of the mounting frame 17. The other side of the steel cable 16 fixed on the mounting plate 15 is connected to the winch 18.

[0041] Below the bottom plate 13, inside the fermentation tank 1, there are evenly arranged liquid outlet pipes 19, and all the liquid outlet pipes 19 extend through the soil layer 11 to the outside; each of the liquid outlet pipes 19 is equipped with a valve.

[0042] Specifically, when it is necessary to ferment the raw materials, the raw materials are added into the fermentation tank 1 and the fermentation tank 1 is sealed for fermentation. During the fermentation process, the fermentation liquid produced in the raw materials will flow through the gap between the bottom plate 13 and the fermentation tank 1 into the space below the bottom plate 13. When the staff needs to release the fermentation liquid, the valve can be opened to release the fermentation liquid.

[0043] After the raw materials have fermented, the workers can first remove the raw materials from the middle of the fermentation tank 1. Then, the winch 18 is controlled to work. During the operation of the winch 18, the steel cable 16 is wound around, thereby pulling the mounting plate 15 upward. As the mounting plate 15 moves upward, it will drive the bottom plate 13 upward through the connecting rod 14. As the bottom plate 13 moves upward, it will push the remaining raw materials upward. During the upward movement of the raw materials, the workers can remove the raw materials that move with the bottom plate 13. At the same time, during the upward movement of the bottom plate 13, the raw materials adhering to the side wall of the fermentation tank 1 can also be pushed upward, thereby performing simple cleaning of the side wall of the fermentation tank 1. When the bottom plate 13 moves to be level with the top of the fermentation tank 1, the winch 18 is controlled to stop working. At this time, the workers can remove the raw materials on the surface of the bottom plate 13. In this process, there is no obstruction from the body of the fermentation tank 1, so the raw materials in the fermentation tank 1 can be cleaned out more easily.

[0044] However, after the fermentation tank 1 has been used for a long time, if the staff needs to clean the space under the bottom plate 13, the staff will control the winch 18 to work. During the operation of the winch 18, the bottom plate 13 can be pulled upward. After the winch 18 pulls the bottom plate 13 out of the fermentation tank 1, the staff can clean the space under the bottom plate 13. The waste liquid generated during the cleaning can be discharged through the liquid outlet pipe 19. After the cleaning is completed, the staff will put the bottom plate 13 back into the fermentation tank 1 and wait for the next use.

[0045] Meanwhile, since the bottom plate 13 can move within the fermentation tank 1 by being pulled by the winch 18, the height of the bottom plate 13 to the top of the fermentation tank 1 will be adjusted during the movement of the bottom plate 13, thereby adjusting the capacity of the fermentation tank 1. When more or less raw material needs to be fermented, the plate can be controlled to move within the fermentation tank 1, thereby adjusting the capacity of the fermentation tank 1 and adapting to the amount of raw material to be fermented.

[0046] In the specific implementation process, a filter layer 2 is provided below the base plate 13, and the filter layer 2 is made of filter cloth;

[0047] The filter layer 2 is initially in a relaxed state;

[0048] The baffle 12 is fixedly connected to a mounting block 21 on one side, and each mounting block 21 is provided with a mounting groove 22; the filter layer 2 is fixedly connected to an insert plate 23 on the side near the mounting block 21, and the insert plate 23 is inserted into the mounting groove 22.

[0049] Specifically, since a filter layer 2 is provided below the bottom plate 13, the liquid flowing down from the gap between the bottom plate 13 and the fermentation tank 1 will first fall onto the filter layer 2. Since the filter layer 2 is made of filter cloth, the liquid flowing through the filter layer 2 will pass through the filter layer 2, and the raw materials mixed in the liquid will be filtered onto the filter layer 2. In this process, the raw materials can be separated from the liquid. At the same time, since the filter layer 2 is in a relaxed state, the raw materials falling onto the filter layer 2 will roll down to the middle position of the filter layer 2 and accumulate, thereby preventing the raw materials from spreading flat on the filter layer 2 and obstructing the flow of liquid.

[0050] Meanwhile, since the filter layer 2 is fixedly connected to the insert plate 23 and the insert plate 23 is inserted into the installation groove 22, after the raw materials in the fermentation tank 1 are cleaned, the staff can choose to pull the bottom plate 13 out of the fermentation tank 1, and then take the insert plate 23 out of the installation groove 22, thereby removing the filter layer 2 from the fermentation tank 1 and cleaning the filter layer 2. After the filter layer 2 is cleaned, the filter layer 2 is then put into the fermentation tank 1, and the insert plate 23 is inserted into the installation groove 22. Then the bottom plate 13 is put into the fermentation tank 1.

[0051] In the specific implementation process, two floats 24 are provided below the baffle 12 at the bottom of the fermentation tank 1; the lower surface of the floats 24 is fixed with evenly arranged pull ropes, and the other side of the pull ropes is connected to the bottom of the fermentation tank 1.

[0052] Specifically, since a float 24 is connected to the bottom of the base plate 13 by a rope, as the fermentation liquid below the base plate 13 gradually increases, the float 24 will move upward with the rise of the liquid level under its own buoyancy. The upward float 24 will come into contact with the filter layer 2, thereby supporting the filter layer 2.

[0053] In the specific implementation process, the two floats 24 are rotatably connected to a rotating rod 25 on opposite sides of the inner wall of the fermentation tank 1, and part of the rotating rod 25 extends into the liquid outlet pipe 19; the outer surface of the rotating rod 25 is fixed with uniformly arranged rotating blades 26, and part of the rotating blades 26 are placed in the liquid outlet pipe 19; the rotating rod 25 is driven by a driving device, which is a motor.

[0054] The outer surface of the blade 26 is covered with a rubber layer;

[0055] Specifically, as the amount of raw material filtered on filter layer 2 gradually increases, filter layer 2 will be stretched and moved downwards. The operator can start the drive device, which will drive the rotating rod 25 to rotate. During the rotation of the rotating rod 25, the rotating blade 26 will rotate. When filter layer 2 comes into contact with the rotating blade 26, the rotating blade 26 can impact filter layer 2. During this process, the raw material above filter layer 2 can be pushed to the middle position of filter layer 2, thereby further preventing the raw material from spreading flat on filter layer 2 and affecting the liquid passing through filter layer 2. At the same time, since the rotating blade 26 is partially inserted into the liquid outlet pipe 19, the cavity of the liquid outlet pipe 19 can be cleaned during the rotation of the rotating blade 26. In addition, since the outer surface of the rotating blade 26 is covered with a rubber layer, when the rotating blade 26 comes into contact with filter layer 2, the friction will be reduced, thereby improving the service life of filter layer 2.

[0056] A baijiu (Chinese liquor) fermentation process, applicable to the aforementioned baijiu fermentation equipment; the process steps are as follows:

[0057] S1: First, put the raw materials to be fermented into fermentation tank 1, and control the temperature of the raw materials to be between 18-20℃ (not exceeding 26℃ in summer);

[0058] S2: The raw materials added to fermentation tank 1 should not be too tightly packed or too loosely packed. Generally, it is advisable to pack about 630-640 kg of chaff per cubic meter of volume. After packing, cover the raw materials with a layer of chaff, seal with pit mud, and then add another layer of chaff.

[0059] S3: Real-time analysis and monitoring of changes in moisture, acidity, alcohol content, and starch residue in raw materials. Fermentation can be terminated when the temperature in fermentation tank 1 rises to 36-37℃.

[0060] After S4 fermentation is completed, the raw materials are removed from fermentation tank 1.
