Description

Technical Field

[0001] This invention relates to the field of intelligent brewing equipment technology, and in particular to a mobile fermentation equipment. Background Technology

[0002] Baijiu is a distilled spirit unique to China. Its unique production process gives it a distinctive flavor profile, with an extremely complex aroma composition, boasting a wide variety of components and a broad range of concentrations, making it arguably the world's most complex distilled spirit. The stacking fermentation process is a crucial step in the production of sauce-aroma baijiu. Specifically, it refers to the process where the mash is exposed to the open environment of the distillery, absorbing microorganisms from the air for fermentation. Traditionally, workers use shovels to shovel the mash onto the distillery floor, forming heaps that ferment for a period of time. Clearly, traditional stacking fermentation relies heavily on manual labor, which is labor-intensive and inefficient.

[0003] The inventor of this application is dedicated to the research of intelligent brewing equipment and applied for an automatic stacking fermentation device with publication number CN114891581A in 2022. The device includes a fermentation chamber with a fermentation bed inside. The fermentation bed includes a frame and a fermentation bin arranged on the frame. One end of the fermentation bin is provided with a feeding bin, and the other end is provided with a discharging bin. A chain conveyor for transporting and supporting the fermentation of the mash is provided inside the fermentation bin. The chain conveyor extends into the feeding bin and the discharging bin. The top of the feeding bin is provided with a feeding port, and the bottom of the discharging bin is provided with a discharging port.

[0004] Analysis reveals that the aforementioned automated stacking fermentation device primarily uses a chain conveyor to support the fermentation of distiller's grains. Therefore, this patent solves the problems of high labor intensity and low efficiency associated with traditional manual stacking fermentation. However, it also has the following drawbacks: First, the equipment occupies a large area, resulting in low space utilization; second, the chain conveyor's high cleanliness and smooth surface make it difficult for microorganisms to adhere to it, and the need for cleaning after each fermentation cycle further hinders microbial adhesion. It is well known that aroma development is a crucial outcome of stacking fermentation, enhancing the flavor and yield of Maotai-flavor liquor. Aroma development is mainly achieved through the action of microorganisms, which explains why older distilleries produce higher-quality liquor—because older distilleries have a greater variety and quantity of microorganisms in their air and fermentation pits. However, the chain conveyor used in the aforementioned application to support the stacking fermentation of distiller's grains has an excessively high cleanliness level, hindering microbial adhesion, and requires cleaning after each fermentation cycle, otherwise affecting the normal operation of the chain conveyor. In summary, because the types and quantities of microorganisms in the aforementioned automatic stacking fermentation device are not abundant, the quality and yield of the liquor produced by distillation from the fermented mash are not optimal. Summary of the Invention

[0005] In view of the technical problems of existing automatic fermentation stacking devices, such as large equipment area, low space utilization, and low quality and yield of alcohol in the distillation process due to the limited variety and quantity of microorganisms, this invention provides a mobile fermentation stacking device.

[0006] The technical solution adopted in this invention is as follows: the mobile fermentation device includes a movable hollow box, which is used to hold the fermented mash to be fermented. The top of the box is an open structure, the top of the box is a feed inlet, the bottom of the box is a discharge outlet, and the bottom of the box is equipped with a material gate assembly that can open and close the discharge outlet. A ventilation assembly is installed inside the box, which is used to introduce gas that helps fermentation of the mash into the box. Multiple boxes can be stacked together.

[0007] Furthermore, the container includes a frame and wooden boards set on the frame, the frame being made of metal; after the fermentation of the mash is completed and the mash is discharged through the outlet, the container does not need to be cleaned, and the next round of fermentation can be repeated.

[0008] Furthermore, the planks are made of pine.

[0009] Furthermore, the material gate assembly includes a pin located at the bottom of the box, with two semi-circular door panels hinged to both sides of the pin. The door panels have pin holes, and the bottom of the box has a pin that matches the pin holes. The end of the pin is connected to a handle, and by rotating the handle, the pin can be driven into the pin hole, thereby locking the door panel.

[0010] Furthermore, rollers are provided at the bottom edge of the door panel.

[0011] Furthermore, it also includes an abutting component, which includes a support column located at the bottom of the door panel near the pin; the end of the support column is provided with an elastic pad to protect the support column; when the material gate is open, the support columns of the two door panels abut against each other, and the two door panels abut against each other at a certain angle; during the process of the box falling and contacting the ground, the two door panels can automatically close the discharge port.

[0012] Furthermore, the ventilation assembly includes an air inlet pipe located at the bottom of the housing, with both ends extending to the outside of the housing. The end of the air inlet pipe outside the housing is connected to a fan via a pipe. Above the air inlet pipe, a ventilation pipe is arranged in a cross shape, and the air inlet pipe is connected to the cross intersection of the ventilation pipe via a connecting pipe. An anti-blocking assembly is provided at the bottom of the ventilation pipe. The anti-blocking assembly includes a baffle arranged at a certain angle at the bottom of the ventilation pipe, with an arc-shaped ventilation plate between the baffles. The ventilation plate has ventilation holes, and the ventilation plate is bolted to the middle of the baffle. The ventilation holes communicate with the ventilation pipe.

[0013] Furthermore, heating components are installed on the pipes.

[0014] Furthermore, the top of the connecting pipe is tapered, and an air vent is provided at the top of the connecting pipe.

[0015] Furthermore, temperature sensors are installed at the top, bottom, center, and sides of the silo inside the container. The temperature sensors, fans, and heating components are electrically connected to the hollow system, and the operating parameters of the fans and heating components are controlled by the temperature sensors.

[0016] The beneficial effects of this invention are: 1. Compared with existing technologies, this invention divides the mash into multiple small piles and puts them into movable boxes for stacking fermentation. This allows for better control and monitoring of various parameters of the mash, improving the stacking fermentation efficiency. Moreover, the multiple boxes can be stacked in the factory area, greatly reducing the equipment's footprint and improving the factory's space utilization. In addition, the entire stacking fermentation process is fully automated, saving time and labor, and is highly efficient.

[0017] 2. This invention selects wooden boards as the main component of the box. The surface of the wooden boards is relatively rough, and the numerous cellulose fibers and fracture holes in the wooden boards provide an ideal habitat for microorganisms, facilitating their attachment. Moreover, since the box does not need to be cleaned and repeated for the next round of fermentation, as the frequency of use of the box increases, the number and types of microorganisms attached to the inner wall of the box will increase and eventually tend to reach a balance, ensuring a stable supply of diverse microorganisms required for the fermentation of the mash, thus ensuring the quality and yield of the alcohol in the subsequent distillation process.

[0018] 3. The abutment component of the present invention allows the two door panels to be arranged at a certain angle under the box after opening. During the process of the crane lowering the box to the ground, the two door panels can automatically close the discharge port without the need for additional manpower or driving device. It has the advantages of simple structure and high efficiency.

[0019] 4. The anti-clogging component of the present invention can prevent the fermentation pores of the fermentation chamber from being squeezed and blocked, ensuring smooth gas flow, accelerating the accumulation and fermentation of the fermentation pores, shortening the fermentation cycle, and improving fermentation efficiency.

[0035] In the description of this invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The following is in conjunction with the appendix Figures 1-14 The present invention will be further described below.

[0038] Example 1 To address the technical problems existing in the background art, the present invention provides a mobile slag stacking device. In the specific technical solution, refer to... Figure 1 and Figure 8 The mobile fermentation device includes a movable hollow box 1, which is used to hold the fermented mash to be fermented. The top of the box 1 is an open structure, which is the feed inlet and the bottom of the box 1 is the discharge outlet. The bottom of the box 1 is equipped with a material gate assembly 2 that can open and close the discharge outlet. A ventilation assembly 3 is installed inside the box 1 to introduce gas that helps ferment the mash into the box 1. Multiple boxes 1 can be stacked together.

[0039] Working principle: Before fermentation, the feed gate assembly 2 is closed, and the fermented mash is loaded into the box 1 through the feed inlet. After the box 1 is full, the top of the mash pile 5 is shaped into a loose bun, and the ventilation assembly is connected to allow the mash to ferment. After fermentation, the overhead crane is connected to the lifting lug 105 on the top of the box 1. After the crane moves the box to the designated area, the feed gate assembly 2 is opened, and the mash in the box 1 is automatically unloaded through the discharge outlet. The weight of the box 1 and the mash inside the box 1 does not exceed 5 tons. Several boxes 1 are required for fermentation. To reduce the occupied area and improve the space utilization of the factory area, multiple boxes 1 can be stacked.

[0040] As can be seen from the above structure and working principle, compared with the prior art, the present invention divides the mash into multiple small piles and puts them into movable boxes for stacking fermentation, which can better control and detect various parameters of the mash and improve the stacking fermentation efficiency; moreover, multiple boxes can be stacked in the factory area, which greatly reduces the area occupied by the equipment and improves the space utilization of the factory area; in addition, the entire stacking fermentation process is fully automated, saving time and labor and achieving high efficiency.

[0041] Specifically, refer to Figure 2 , Figure 3 and Figure 4In this embodiment, the material gate assembly 2 includes a pin 201 disposed at the bottom of the box body 1. Two semi-circular door panels 202 are hinged to both sides of the pin 201. The door panels 202 are provided with pin holes 203. The bottom of the box body 1 is provided with a pin 103 that matches the pin holes 203. The end of the pin 103 is connected to a handle 104. By rotating the handle 104, the pin 103 can be driven to extend into the pin holes 203, thereby locking the door panels 202.

[0042] Working principle: When it is necessary to open the material gate assembly 2, push the handle 104 toward one side of the box 1. The bottom of the handle 104 will move toward one side of the box 1, thereby driving the pin 103 connected to the bottom of the handle 104 to move synchronously. After the pin 103 is completely removed from the pin hole 203, the material gate assembly 2 and the box 1 are unlocked. At this time, the box 1 is lifted, the door panel 202 is automatically opened, and the mash falls smoothly from the discharge port.

[0043] Specifically, refer to Figure 4 In this embodiment, the ventilation component 3 includes an air inlet pipe 301 disposed at the bottom of the housing 1. Both ends of the air inlet pipe 301 extend to the outside of the housing 1. The end of the air inlet pipe 301 located outside the housing 1 is connected to a fan (not shown in the figure) via a pipe (not shown). A ventilation pipe 302 is arranged in a cross shape above the air inlet pipe 301, and the air inlet pipe 301 is connected to the cross intersection of the ventilation pipes 302 via a connecting pipe 303. The top of the connecting pipe 303 is conical, and an air outlet 304 is provided at the top of the connecting pipe 303. The introduced gas can be air, or atomized bacterial liquid can be added.

[0044] Example 2 The existing automated stacking fermentation device's chain conveyor has an excessively high cleanliness level and a smooth surface, making it difficult for microorganisms to adhere to it. Furthermore, the chain conveyor requires cleaning after each fermentation cycle, which is detrimental to microbial adhesion. It is well known that aroma development is a crucial outcome of stacking fermentation, enhancing the flavor and yield of Maotai-flavor liquor. Aroma development primarily occurs through the action of microorganisms, which explains why older distilleries produce higher-quality liquor—because older distilleries have a greater variety and quantity of microorganisms in their air and fermentation pits. However, the chain conveyor used in the aforementioned application to support the stacking fermentation of distiller's grains has an excessively high cleanliness level, hindering microbial adhesion, and requires cleaning after each fermentation cycle, otherwise, it will affect the normal operation of the chain conveyor.

[0045] Therefore, in view of the above-mentioned technical problems, based on Embodiment 1, this embodiment makes the following further improvements to the housing: (Refer to...) Figure 1 , Figure 2 and Figure 3In this embodiment, the box 1 includes a frame 101 and a wooden board 102 disposed on the frame 101. The frame 101 is made of metal. The frame 101 serves as a rigidity and ensures the strength of the entire box 1.

[0046] It is worth noting that in this embodiment, after the fermentation of the mash is completed and discharged through the outlet, the container 1 does not need to be cleaned and can be used for the next round of fermentation. This is the first application of this technology in the field, and its effectiveness has been demonstrated in practice. Wooden boards were chosen as the main component of the container because their rough surface and the numerous cellulose fibers and fracture surfaces provide an ideal habitat for microorganisms, facilitating their attachment. Furthermore, since the container 1 is not cleaned for repeated fermentation, the number and types of microorganisms attached to the inner wall of the container increase with the frequency of use, eventually reaching a balance. This ensures a stable supply of diverse microorganisms required for the fermentation of the mash, guaranteeing the quality and yield of the alcohol in the subsequent distillation process.

[0047] In this embodiment, the wooden board 102 is preferably made of pine wood, which is cost-effective and easy to carbonize, leaving no odor and allowing bacteria to survive.

[0048] Example 3 In traditional bottom-opening door systems, there are no locking mechanisms on the door panel to control its opening angle. When opened, the door naturally swings down 90 degrees under its own weight, returning from a horizontal to a vertical position. Closing the door requires manual pulling or a drive mechanism to rotate it, making the process extremely difficult.

[0049] Therefore, to facilitate automatic closing of the door panel, this embodiment further improves the door panel as follows, based on Embodiment 1: (Refer to...) Figure 2 In this embodiment, an abutting component is also provided, which includes a support column 205 located at the bottom of the door panel 202 near the pin 201; the end of the support column 205 is provided with an elastic pad 206 that protects the support column 205; when the material gate is open, the support columns 205 of the two door panels abut against each other, and the two door panels 202 abut against each other form a certain angle, which is 60°; during the process of the box 1 falling and contacting the ground, the two door panels 202 can automatically close the discharge port.

[0050] Working principle: Refer to Figure 2In this embodiment, during unloading, the mobile stacking device has a 60° angle between the two door panels 202 due to the support column 205, causing the door panels 202 to be tilted rather than vertical. Therefore, after unloading, during the process of the crane lowering the container 1 to the ground, because the door panels 202 are tilted, as the door panels 202 gradually come into contact with the ground, under the action of the ground support force, the door panels 202 gradually rotate around the pivot pin 201 toward the rotating container, thereby automatically closing the discharge port, and finally locking it with a latch.

[0051] As can be seen from the above structure and working principle, the abutment component of the present invention can make the two door panels tilted at a certain angle under the box after opening. During the process of the crane lowering the box to the ground, the two door panels can automatically close the discharge port without the need for additional manpower or driving device to drive it. It has the advantages of simple structure and high efficiency.

[0052] In order to protect door panel 202, refer to Figure 2 Therefore, this embodiment also provides rollers 204 on the bottom edge of the door panel 202. Without rollers 204, the door panel 202 would rub directly against the ground during closing, potentially causing damage. Therefore, this embodiment provides rollers 204 on the bottom edge of the door panel 202. During closing, the door panel 202 rolls and rubs against the ground via the rollers 204, thus protecting both the ground and the door panel. Furthermore, the rollers facilitate the transport of the container on the ground.

[0053] Example 4 The traditional way to set the vent is to place it directly on the vent pipe. The drawback of this method is that the vent is easily blocked by slag, which will cause the air intake to fail.

[0054] Therefore, in view of the above-mentioned technical problems, based on Embodiment 1, this embodiment makes the following further improvements: (Refer to...) Figure 1 In this embodiment, an anti-blocking component 4 is also provided at the bottom of the vent pipe 302.

[0055] Specifically, refer to Figure 5 , Figure 6 and Figure 7 The anti-blocking component 4 includes a baffle 401 arranged at a certain angle at the bottom of the vent pipe 302, an arc-shaped vent plate 402 between the baffles 401, a vent hole 403 on the vent plate 402, and the vent plate 402 is connected to the middle of the baffle 401 by bolts 404. The vent hole 403 is connected to the vent pipe 302.

[0056] Working Principle: First, the anti-clogging component in this embodiment is located at the bottom of the vent pipe 302, which prevents the vent hole 403 from directly compressing the fermented mash above the vent pipe 403. Second, the two inclined baffles 401 and the side plate provide space for gas flow, preventing the fermented mash from accumulating below the vent hole 403. Furthermore, the vent plate 402 is connected to the middle of the baffle 401 by bolts 404, creating a certain distance between the bottom of the vent plate 402 and the baffle 401, which also effectively prevents the fermented mash from clogging the vent hole. In summary, the anti-clogging component of this invention can prevent the fermented mash in the tank from compressing and clogging the vent hole, ensuring smooth gas flow, accelerating the accumulation and fermentation of the fermented mash, shortening the fermentation cycle, and improving fermentation efficiency.

[0057] This embodiment also includes a heating component (not shown in the figure) installed on the pipeline. The heating component can be a surface heater. The heating component can adjust the temperature of the gas introduced, especially in cold winters, to facilitate rapid heating of the mash and improve fermentation efficiency.

[0058] In this embodiment, temperature sensors (not shown in the figure) are also installed at the top, bottom, center and sides of the slag pile inside the box 1. The temperature sensors, fans and heating components are electrically connected to the hollow system, and the operating parameters of the fans and heating components are controlled by the temperature sensors.

[0059] Example 5 Box-based fermentation experiment.

[0060] Equipment: 1 set of mobile slag stacking device, sampler, several temperature measuring rods, rake, shovel, and broom.

[0061] Location: The storage and drying area of ​​a brewing workshop.

[0062] Source of waste: the waste from the fifth round of ground-level heaping that is about to be completed (discarded).

[0063] Control group: Fifth round of ground-based large stacks, with thermometers inserted at the core, top, bottom and sides of the stack for temperature measurement.

[0064] Experimental group: A mobile piling device filled with fermented mash, with the top shaped into a loose bun, connected to a ventilation device, and thermometers inserted at the same position and depth as the ground pile to measure the temperature (pile core, pile top, pile bottom, and pile side).

[0065] Track and compare temperature changes, check the temperature every day before work and supply oxygen in a timely manner (10-30 minutes), record and compare temperature changes every 4 hours (morning, noon, evening), and adjust the oxygen supply operation according to the temperature rise and sensory physicochemical conditions.

[0066] Table 1: Temperature Records After Stacking Plot the data from Table 1 above into a curve graph, and refer to... Figures 9-14 .

[0067] Reference Figure 9 and Figure 10 Analysis: The overall temperature of the wooden barrel pile was higher than that of the ground pile, and the temperature rise and top fire occurred about 10 hours earlier than that of the ground pile. However, the time when the wooden barrels were dropped into the pile was about 1 hour and 36 minutes later than that of the ground pile. Considering that the process of piling the ground pile lasted for more than 12 hours, and that the piling mash that had already been piling mash had been treated with Daqu microorganisms and had a continuous microbial network during the piling process, it is believed that the actual piling time of the wooden barrels should be 10-20 hours shorter than that of the ground pile.

[0068] Reference Figure 11 Analysis: The temperature of the top pile of wooden barrels was 1.9℃ higher than that of the large pile on the ground. The temperature of the top fire of the wooden barrels was 0.7℃ higher than that of the large pile on the ground. The temperature of the mash at the top of the wooden barrels dropped by about 3℃. Considering the time of dropping the mash, the time for the top of the wooden barrels to rise was about 11 hours shorter than that of the large pile on the ground.

[0069] Reference Figure 12 Analysis: The temperature of the barrel pile in the reactor core was 3°C higher than that of the ground pile, and the temperature of the barrel pile at the top of the fire was 7.4°C higher than that of the ground pile. The temperature rise was significantly higher in the barrel pile than in the ground pile, and the temperature rise rate accelerated significantly in the later stages of the process. In contrast, the ground pile heated up slowly, with a temperature rise of only 2.9°C, and the temperature dropped in the later stages. This indicates that the aeration and oxygen supply in the reactor core promoted the reproduction and growth of microorganisms, providing conditions for metabolic heat production and temperature rise.

[0070] Reference Figure 13 Analysis: The temperature of the barrel pile on the side was 2.1℃ higher than that of the ground pile, and the temperature of the top fire pile was 6.1℃ higher than that of the ground pile, a temperature increase of 10.5℃, while the temperature increase of the ground pile was only 6.5℃, a difference of 4℃. This indicates that the barrel pile generates more heat during fermentation and exhibits more active microorganisms.

[0071] Reference Figure 14 Analysis: The temperature of the barrel pile at the bottom was 2.3℃ higher than that of the large pile on the ground, and the temperature of the barrel pile at the top of the fire was 2.2℃ higher than that of the large pile on the ground. The difference in temperature rise was not significant, and the temperature rise curves showed similar trends, with both showing a downward trend in the later stages.

It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
