Description

Technical Field

[0001] This invention belongs to the field of liquor brewing technology, and particularly relates to a box-type aerobic fermentation system and process for liquor mash. Background Technology

[0002] Currently, in the brewing process of Maotai-flavor liquor, the "ground-piling" method is often used to carry out aerobic fermentation of the mash to obtain the mash pile for fermentation in the cellar. This method has a low degree of mechanization, requires a lot of manpower and resources, and the control of fermentation temperature and humidity largely depends on human experience. For workers with less experience, the mash produced may not meet the requirements, which can easily lead to waste. At the same time, the "ground-piling" fermentation method requires processes such as "breaking and shifting" and "turning the pile" to increase the contact between the mash and air. In extreme environments, this operation will increase labor and time costs, resulting in lower brewing efficiency and higher cost of high-quality liquor. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a box-type aerobic fermentation system and process for mash, which can effectively solve the problems of high labor costs, time costs, and reliance on human experience in the "ground-piling" mash fermentation method, thereby improving brewing efficiency and reducing the cost of high-quality wine.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A box-type aerobic fermentation system for fermented mash includes multiple fermentation modules arranged in sequence. Each fermentation module includes a fermentation rack and a cellar pit arranged opposite each other. The cellar pit is located below ground and is used to hold the mash undergoing aerobic fermentation in the fermentation box. The fermentation rack has multiple fermentation compartments for placing the fermentation box. Adjacent fermentation modules are symmetrically arranged, and the cellar pits of the fermentation modules are close to each other. A spreading and cooling device is arranged between two adjacent cellar pits. Each fermentation module also includes a secondary piling device located at one end of the cellar pit. An upper tray system is arranged between two adjacent fermentation modules. The fermentation rack and the cellar pit are connected. AGVs are installed between the fermentation pits. The AGVs are used to transport fermentation boxes. Each fermentation box includes a tray and a container body placed on the tray. The AGV is equipped with a tilting component to tilt the mash inside the container. Temperature and humidity sensors are installed inside the container. A weight sensor is also installed at the bottom of the container body. An AGV upper management system electrically connected to the temperature and humidity sensors and the weight sensor is installed on the side wall of the container body. The signal transmission device is electrically connected to the scheduling system on the AGV so that the AGV can transport the fermentation box to the fermentation rack or to the secondary stacking device.

[0006] In one embodiment, the fermentation rack includes multiple fermentation chambers stacked on top of each other, each fermentation chamber having multiple evenly spaced fermentation grids, and each fermentation grid having a spray device on top.

[0007] In one embodiment, the temperature and humidity sensor is vertically positioned in the center of the fermentation chamber, with the probe at its top being 10 to 20 centimeters away from the top of the fermentation chamber.

[0008] In one embodiment, the fermentation box is provided with clamping structures on both sides, and multiple ventilation holes are also provided on the side wall of the fermentation box.

[0009] In one embodiment, the flipping assembly includes a flippable platform mounted on an AGV, one end of which is hinged to the base plate of the AGV and the other end is connected to a support mechanism, and the fermentation tank is mounted on the flippable platform.

[0010] In one embodiment, the secondary stacking device includes a turning platform and a telescopic frame disposed at the bottom of the turning platform. The turning platform has an openable opening component in the middle, and a turning hopper is disposed at the bottom of the opening component.

[0011] In one embodiment, the bottom tray has two through slots.

[0012] In one embodiment, a spreading trolley is also included, which has a spreading structure. The spreading trolley and the mixing system are located at opposite ends of the cellar, and the spreading trolley is electrically connected to the AGV. In this embodiment, the spreading trolley is connected to the AGV to evenly spread the successfully fermented mash into the cellar.

[0013] In one embodiment, the upper tray system is located at the end of the spreading and drying equipment and close to the conveyor belt of the turning and mixing system.

[0014] This invention provides a box-type aerobic fermentation process for brewing mash, based on the aforementioned box-type aerobic fermentation system for brewing mash, comprising the following steps:

[0015] Step S1: After the fermented mash has been cooled and spread out, it is transferred to the fermentation box and piled up.

[0016] Step S2: Transfer the fermentation box to the fermentation rack using an AGV to allow the mash to undergo aerobic fermentation;

[0017] Step S3: Monitor and report data such as temperature and humidity in the fermentation chamber in real time, and turn on the spray system to increase humidity or adjust the temperature as needed.

[0018] Step S4: When the humidity and temperature in the fermentation box reach the target threshold, the fermentation box is removed from the fermentation rack by AGV and the mash inside is poured into the cellar for fermentation by a cloth cart.

[0019] When the humidity or temperature in the fermentation tank does not reach the target threshold, the fermentation tank is transferred to the secondary stacking device by AGV. After the stacking operation is completed, the mash is put into the fermentation tank and the aerobic fermentation step S2 is repeated.

Detailed Implementation

[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] This invention provides a box-type aerobic fermentation system for wine mash, such as... Figure 1 and Figure 2 As shown, the system includes multiple fermentation modules arranged in sequence. Each fermentation module includes a fermentation rack 1 and a cellar 2 arranged opposite each other. The cellar 2 is located below ground level and is used to hold the mash undergoing aerobic fermentation in the fermentation tank 6. The fermentation rack 1 has multiple fermentation compartments for placing the fermentation tank 6. Adjacent fermentation modules are arranged symmetrically, and the cellars 2 of the fermentation modules are close to each other. A spreading and cooling device 8 is installed between two adjacent cellars 2. The fermentation module also includes a secondary piling device 4 installed at one end of the cellar 2. A top-loading system 3 is installed between two adjacent fermentation modules. An AGV 5 is installed between the fermentation rack 1 and the cellar 2. AGV5 is used to transport fermentation box 6. Fermentation box 6 includes a tray 601 and a box body 602 set on the tray 601. AGV5 is equipped with a tilting component to tilt the mash in box body 602. Temperature and humidity sensors 603 are installed inside box body 602. Weight sensors are also installed at the bottom of box body 602. Signal transmission device 605, which is electrically connected to temperature and humidity sensors 603 and weight sensors, is installed on the side wall of box body 602. Signal transmission device 605 is electrically connected to the scheduling system on AGV5 so that AGV5 can transport fermentation box 6 to fermentation rack 1 or to turning platform 402.

[0035] It should be noted that, in this embodiment, as Figure 1As shown, two fermentation modules are symmetrically arranged, with the cellars 2 in the two fermentation modules close to each other. A spreading and cooling device 8 is set between the cellars 2 to spread and cool the mash. An AGV5 is set between the fermentation rack 1 and the cellar 2. The AGV5 is used to transport the fermentation box 6, moving it along the length of the fermentation rack 1. The temperature and humidity sensors 603 and the signal transmission device 605 set in the fermentation box 6 control the AGV5, so that the AGV5 can transfer the mash to the fermentation rack 1, or to the secondary mixing device 4 for stirring and piling, or to the cellar 2 for fermentation, depending on the fermentation situation. In other words, through the layout system in this embodiment, intelligent brewing is realized, improving brewing efficiency and quality, greatly reducing heavy manual labor and management difficulty, and reducing the cost of high-quality wine.

[0036] Specifically, such as Figure 6 As shown, the flipping assembly includes a flipping platform 11 mounted on the AGV5. One end of the flipping platform 11 is hinged to the bottom plate of the AGV5, and the other end is connected to the support mechanism 12. The fermentation box 6 is mounted on the flipping platform 11.

[0037] In one embodiment, such as Figure 3 As shown, the fermentation rack 1 includes multiple fermentation chambers stacked one on top of the other. Each fermentation chamber contains multiple evenly spaced fermentation cells, and each fermentation cell is equipped with a spray device on top. This allows for spraying and humidifying the mash as needed, depending on its humidity. Meanwhile, each fermentation box 6 is placed in a separate fermentation cell. This means that multiple fermentation boxes 6 placed on the fermentation rack 1 at different stages are likely to be in different fermentation states. One spray nozzle is used for each fermentation box 6, and spraying is performed individually.

[0038] In one embodiment, the temperature and humidity sensor 603 is vertically positioned in the center of the fermentation tank 6, with the probe at its top being 10 to 20 centimeters away from the top of the fermentation tank 6. This allows for real-time monitoring of the state of the mash in the upper middle part of the fermentation tank 6, thus obtaining the approximate fermentation state of the entire fermentation tank 6. Compared to relying on human experience, this method is more effective in ensuring the quality of the brewed wine.

[0039] In one embodiment, such as Figure 2 As shown, the fermentation box 6 has clamping structures on both sides, and multiple ventilation holes 604 are opened on the side wall of the fermentation box 6. Two through slots are opened on the bottom tray 601. The clamping structures facilitate the movement of the fermentation box 6, and the multiple ventilation holes 604 on the side wall of the fermentation box 6 are opened to release the gas during the fermentation of the mash.

[0040] In one embodiment, such as Figure 4 and Figure 5As shown, the secondary piling device 4 includes a turning platform 402 and a telescopic frame set at the bottom of the turning platform 402. The turning platform 402 has an openable opening component 401 in the middle, and a turning hopper 403 is set at the bottom of the opening component 401. The turning platform 402 is normally in a flat state. The telescopic frame allows the turning platform 402 to be raised and lowered. Its initial position is at a low position. After the turning is completed, it rises to a certain height and then the opening component 401 in the middle is opened, so that the mash can be evenly sprinkled into the fermentation tank 6 from the opening.

[0041] In one embodiment, such as Figure 1 As shown, it also includes a material spreading trolley 9, which has a material spreading structure. The material spreading trolley 9 and the turning and mixing system 4 are located at opposite ends of the cellar. The material spreading trolley 9 is electrically connected to the AGV5. The upper sieve system 3 is set at the end of the spreading and drying equipment 8 and close to the conveyor belt of the turning and mixing system 4. The layout of the whole system facilitates the transfer of materials by the AGV5 and also saves construction costs. The material spreading trolley 9 can dock with the AGV5 and spread the unfermented lees evenly into the cellar 2 through the material spreading trolley 9.

[0042] In one embodiment, such as Figure 7 As shown, the present invention also provides a box-type aerobic fermentation process for brewing mash, comprising the following steps:

[0043] Step S1: After the fermented mash has been cooled and spread out, it is transferred to the fermentation box and piled up.

[0044] Step S2: Transfer the fermentation box to the fermentation rack using an AGV to allow the mash to undergo aerobic fermentation;

[0045] Step S3: Monitor and report data such as temperature and humidity in the fermentation chamber in real time, and turn on the spray system to increase humidity or adjust the temperature as needed.

[0046] Step S4: When the humidity and temperature in the fermentation box reach the target threshold, the fermentation box is removed from the fermentation rack by AGV and the mash inside is poured into the cellar for fermentation by a cloth cart.

[0047] When the humidity or temperature in the fermentation tank does not reach the target threshold, the fermentation tank is transferred to the secondary stacking device by AGV. After the stacking operation is completed, the mash is put into the fermentation tank and the aerobic fermentation step S2 is repeated.

[0048] In this embodiment, the fermentation process is used to achieve automated control of the fermentation process and effect of the mash, realize intelligent brewing, and greatly reduce heavy manual labor.
