Description

Technical Field

[0001] This utility model belongs to the field of liquor brewing technology, and more specifically it relates to a steaming device for liquor brewing. Background Technology

[0002] In the brewing process of baijiu (especially traditional solid-state fermented baijiu), "steaming" is an extremely crucial step. This process requires the operator to evenly and loosely spread the fermented mash onto the surface of the still, forming a layer of mash suitable for even steam penetration. The quality of steaming directly determines the efficiency of subsequent distillation, the yield, and the quality and flavor of the baijiu.

[0003] Traditional manual steaming relies heavily on the experience, focus, and physical strength of the operators. During the steaming process, the operator must constantly observe the steam escaping from the surface of the mash in the steamer (the "steaming upon seeing steam" principle), especially those areas of weak, barely perceptible steam that are "about to escape." If these areas are not covered with fresh mash in a timely and accurate manner, valuable aroma and flavor compounds will be lost as they "escape" with the steam.

[0004] Meanwhile, manual operation makes it difficult to maintain consistent and uniform application of the ingredients, easily leading to uneven density of the mash layer, air compression, or steam leakage, ultimately affecting the yield and stability of the liquor's quality. Furthermore, the steaming environment is characterized by high temperature and humidity, resulting in high labor intensity and relatively low efficiency. Therefore, there is an urgent need for a steaming device for baijiu brewing to solve these problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steaming device for brewing baijiu, which has the advantage of improving the steaming efficiency by accurately finding the escaping area and evenly spreading the mash.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A still-brewing device for baijiu (Chinese liquor) includes a still and further comprises: a conveying assembly mounted on a robotic arm for conveying mash; a spreading assembly mounted at one end of the conveying assembly for receiving the mash conveyed by the conveying assembly; the spreading assembly includes: a conical collecting funnel mounted at the end of the conveying assembly for pre-collecting the mash conveyed by the conveying assembly; a spreading box mounted at the bottom of the conical collecting funnel and connected to the conical collecting funnel through a connecting port; a dispersing device horizontally mounted inside the spreading box through a bearing seat; and a detection assembly mounted directly above the still for detecting the temperature and / or escaping areas inside the still.

[0008] The advantages of this scheme are at least as follows: the cooperation of the robotic arm and the conveying components enables automated transport of the mash, reducing manual intervention and labor intensity. At the same time, the detection components enable the detection of temperature and / or escaping areas inside the still. The design of the spreading components uses a dispersing device to break up the mash transported to the spreading box to prevent clumping. The mash is then evenly spread in the escaping areas inside the still, avoiding local accumulation or uneven spreading, ensuring consistent fermentation results and improving the quality of the liquor.

[0009] The present invention is further configured as follows: the conveying assembly includes: a support rod, fixed on the robotic arm for supporting the conveying assembly; a conveying device including a frame, a drive roller, a driven roller, and a belt, wherein the drive roller and the driven roller are mounted on the frame, and the belt covers the drive roller and the driven roller; the frame is fixedly mounted on the top of the support rod; a drive device, fixedly mounted on the frame and connected to the drive roller via a reducer; and a feed inlet fixed above the starting end of the conveying device.

[0010] The advantages of this scheme are at least as follows: through the reasonable layout of the support rod, frame, drive roller, driven roller and belt, and the transmission connection of the drive device, and the design of the feed inlet to facilitate the input of mash, during operation, the mash falls from the feed inlet onto the belt of the conveyor device. The drive device drives the drive roller and driven roller through the reducer to work together to tension the belt and convey the mash, thereby conveying the mash into the spreader, thus achieving stable and reliable material conveying.

[0011] The present invention is further configured to include a shielding component, which is fixedly installed on the top of the frame by a connector. The shielding component includes a first shielding plate and a second shielding plate, which are symmetrically installed on both sides of the conveying device and are both welded from L-shaped plates and several reinforcing ribs.

[0012] The advantages of this scheme are at least as follows: by setting the first and second shielding plates to protect the conveying device, the mash is prevented from splashing outwards or being affected by wind during transportation, thus ensuring the stability of the conveying process.

[0013] The present invention is further configured such that the dispersing device includes a first auger and a second auger, the first auger and the second auger being rotatably installed inside the spreading box, and the spiral blades of the first auger and the second auger being staggered.

[0014] The advantages of this scheme are at least as follows: after the conveying component feeds the mash into the conical collection funnel, the mash enters the spreading box. At this time, the first and second augers rotate under the drive of the motor, and the staggered spiral blades fully disperse the mash, making it loose and uniform. This effectively disperses the conveyed mash, prevents it from clumping, and ensures the uniformity of spreading.

[0015] The present invention is further configured such that the spreading component also includes a transmission belt, which is laid on the upper surface of the bottom plate of the spreading box for spreading the dispersed mash onto the steamer.

[0016] The advantages of this scheme are at least as follows: the transmission belt is laid and moves on the surface of the bottom plate of the spreading box, spreading the mash evenly into the steamer, thereby achieving uniform spreading of the dispersed mash in the steamer and improving spreading accuracy and efficiency.

[0017] The present invention is further configured such that: the detection component includes: a first linear module, a second linear module, and an infrared thermal imaging camera; the second linear module is horizontally and vertically arranged on the first linear module and is driven to move linearly by the first linear module, and the infrared thermal imaging camera is mounted on the second linear module.

[0018] The advantages of this scheme are at least as follows: when the first and second linear modules work together, the camera can scan the space above the steamer. The first linear module is responsible for moving in the horizontal direction (X-axis), while the second linear module is responsible for moving in the other horizontal direction (Y-axis). This combined movement allows the camera to cover different areas inside the steamer, thus enabling comprehensive monitoring of temperature and steam emission.

[0019] The present invention is further configured such that: a discharge port is provided on the spreading box, a mesh plate is installed at the discharge port, a baffle plate is provided at the front end of the discharge port, the baffle plate is slidably installed on the spreading box and fixed by fasteners.

[0020] The advantages of this scheme are at least as follows: the design of the strainer plate can effectively filter out large impurities and foreign objects in the mash, ensuring that the mash entering the still is uniform and fine, thus improving the brewing quality; the baffle plate is slidably installed on the spreading box, and with the fasteners, the size of the discharge port can be flexibly adjusted to adapt to different spreading needs, thus improving the versatility of the equipment. When it is necessary to increase the discharge volume, the baffle plate is slid upward; when it is necessary to decrease the discharge volume, the baffle plate is slid downward.

[0021] The present invention is further configured such that the fastener is a butterfly locking bolt.

[0022] The advantages of this solution are at least as follows: the design of the butterfly locking bolt is ergonomic, the operation is simple, no tools are needed, and the baffle plate can be fixed and adjusted quickly.

[0023] The present invention is further configured such that the transmission belt is an adjustable speed conveyor belt.

[0024] The advantages of this scheme are at least as follows: the adjustable speed function allows the transmission belt to precisely control the spreading thickness and range by accurately controlling the speed of the transmission belt according to the size of the still, the nature of the mash, and the requirements of the brewing process, thereby improving production accuracy and quality.

[0025] The present invention is further configured such that: the conveying device is also provided with a tensioning component, the tensioning component includes a sliding seat and an adjusting screw; the sliding seat is slidably mounted on the frame, and the driven roller is rotatably mounted on the sliding seat through a rolling bearing; one end of the adjusting screw is rotatably connected to the sliding seat, and the other end is threadedly connected to the frame.

[0026] The advantages of this scheme are at least as follows: through the cooperation of the sliding seat and the adjusting screw, the tensioning component can effectively adjust the tension of the conveying device, ensuring that the conveying device always maintains appropriate tension during operation and avoiding slippage or deviation caused by slack.

[0027] In summary, this utility model has at least the following advantages:

[0028] 1. By setting up conveying, spreading, and detection components, and through the cooperation of robotic arms and conveying components, the mash is automatically conveyed, reducing manual intervention and labor intensity. At the same time, the detection component is used to detect the temperature and / or escaping areas inside the still. The design of the spreading component uses a dispersing device to disperse the mash conveyed to the spreading box to prevent it from clumping. Then, the mash is evenly spread in the escaping areas inside the still, avoiding local accumulation or uneven spreading, ensuring consistent fermentation effect and improving the quality of baijiu.

[0029] 2. By setting up a shielding component, the first shielding plate and the second shielding plate are set up to shield the conveying device, which prevents the mash from splashing outwards or being affected by wind during transportation, thus ensuring the stability of the conveying process.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0039] Example 1

In some preferred embodiments, in order to facilitate observation of the material condition on the conveying device 202, observation ports are respectively opened on the first shielding plate 2051 and the second shielding plate 2052, and transparent plexiglass or acrylic plates are installed as observation windows to facilitate observation of the material condition on the conveying device 202.

[0043] Example 2

[0044] like Figure 3 , Figure 4As shown, the spreading assembly 3 includes: a conical collecting funnel 301, installed at the end of the conveying assembly 2, for pre-collecting the mash conveyed by the conveying assembly 2; a spreading box 302, installed at the bottom of the conical collecting funnel 301, and connected to the conical collecting funnel 301 through a connecting port; and a dispersing device 303, horizontally installed in the inner cavity of the spreading box 302 through a bearing seat.

[0045] In some embodiments, to better disperse the mash, the dispersing device 303 includes a first auger 3031 and a second auger 3032, which are rotatably mounted inside the spreading box 302, with the spiral blades of the first auger 3031 and the second auger 3032 staggered. The first auger 3031 and the second auger 3032 are connected by a synchronous gear set and driven by the same drive motor.

[0046] In other preferred embodiments, to better disperse the mash, dispersing teeth can be detachably installed on the spiral blades of the first auger 3031 and the second auger 3032. The dispersing teeth can be designed in different shapes (such as sawtooth, conical, etc.). According to the characteristics of different materials, appropriate dispersing teeth can be selected to improve the dispersing effect. In some preferred embodiments, a buffer hopper can also be added above the dispersing device 303. The buffer hopper is a funnel-shaped structure that is wider at the top and narrower at the bottom. It is installed between the conical collecting funnel 301 and the dispersing device 303. Its function is to buffer the mash conveyed from the conveying component 2, so that the mash can enter the dispersing device 303 evenly, reduce the impact on the dispersing device 303, and improve the dispersing effect.

[0047] like Figure 4 As shown, in order to evenly spread the dispersed mash in the steam venting area of ​​the still 1, in some embodiments, the spreading assembly 3 further includes a transmission belt 304, laid on the upper surface of the bottom plate of the spreading box 302, for spreading the dispersed mash on the still 1. Furthermore, the transmission belt 304 is an adjustable speed conveyor belt. The transmission belt 304 is laid on and moves on the upper surface of the bottom plate of the spreading box 302, spreading the mash evenly into the still 1. The adjustable speed function of the transmission belt 304 allows for precise control of the spreading thickness and range by accurately controlling the rotational speed of the transmission belt 304 according to the size of the still 1, the properties of the mash, and the requirements of the brewing process, thereby improving production accuracy and quality.

[0048] In some embodiments, the bottom of the spreading box 302 may also be an inclined structure, and the transmission belt 304 is installed along the inclined direction to move the dispersed mash evenly towards the discharge port 5 and spread it into the steamer 1, thereby improving the uniformity and efficiency of spreading. In a preferred embodiment, in order to prevent the mash from clogging in the spreading box 302 and to ensure the smooth progress of the spreading process, the spreading assembly 3 also includes a vibration device (not shown in the figure). The vibration device is specifically a vibration motor, which is installed at the bottom of the spreading box 302. It is used to generate vibration during the spreading process of the dispersed mash to effectively break the adhesion between the mash and the conveyor belt, and to ensure that the mash is completely and smoothly transported from the transmission belt 304 into the steamer 1.

[0049] like Figure 4 As shown, to facilitate the control of the mash flow rate at the discharge port 5, in some embodiments, the spreading box 302 is provided with a discharge port 5, a mesh screen 6 is installed at the discharge port 5, and a baffle plate 7 is provided at the front end of the discharge port 5. The baffle plate 7 is slidably installed on the spreading box 302 and fixed by fasteners 8. It is worth mentioning that the fastener 8 is a butterfly locking bolt. The butterfly locking bolt is ergonomically designed, easy to operate, and can quickly fix and adjust the baffle plate 7 without the need for tools.

[0050] The design of the strainer plate 6 can effectively filter out large impurities and foreign objects in the mash, ensuring that the mash entering the still 1 is uniform and delicate, thus improving the brewing quality. The baffle plate 7 is slidably installed on the spreading box 302, and with the fasteners 8, the size of the discharge port 5 can be flexibly adjusted to adapt to different spreading needs, thus improving the versatility of the equipment. When it is necessary to increase the discharge volume, the baffle plate 7 is slid upward; when it is necessary to decrease the discharge volume, the baffle plate 7 is slid downward.

[0051] like Figure 5 As shown, to ensure that the conveying device 202 maintains appropriate tension during operation, in some embodiments, the conveying device 202 is further provided with a tensioning assembly 9. The tensioning assembly 9 includes a sliding seat 901 and an adjusting screw 902. The sliding seat 901 is slidably mounted on the frame 2021, and the driven roller 2023 is rotatably mounted on the sliding seat 901 via a rolling bearing. One end of the adjusting screw 902 is rotatably connected to the sliding seat 901, and the other end is threadedly connected to the frame 2021. The tensioning assembly 9 can effectively adjust the tension of the conveying device 202, avoiding slippage or deviation caused by slack. In some embodiments, to facilitate the rotation of the adjusting screw 902, a handwheel is installed at the end of the adjusting screw 902. The tension of the conveying device 202 is adjusted by rotating the handwheel, avoiding the need for tools for adjustment.

[0052] Example 3

[0053] like Figure 1 As shown, the detection component 4 includes: a first linear module 401, a second linear module 402, and an infrared thermal imaging camera 403; the second linear module 402 is horizontally and vertically arranged on the first linear module 401 and is driven to move linearly by the first linear module 401, and the infrared thermal imaging camera 403 is mounted on the second linear module 402.

[0054] The first linear module 401 and the second linear module 402 are mounted directly above the steamer 1 via a gantry frame. Specifically, they are screw-driven linear modules, including a screw, a nut seat, a linear guide rail, and a drive motor. The screw is mounted on one side of the linear guide rail, the nut seat mates with both the screw and the linear guide rail, and the mounting base of the second linear module 402 is fixed to the nut seat. The drive motor is connected to the lead screw via a coupling, driving the lead screw to rotate, thereby causing the nut seat to move linearly along the linear guide rail. The infrared thermal imaging camera 403 is fixedly mounted on the nut seat of the second linear module 402. In use, the drive motor on the first linear module 401 is started, and the drive motor drives the nut seat to move along the linear guide rail via the lead screw, thereby causing the second linear module 402 to move in the X direction. The drive motor on the second linear module 402 is started, and the drive motor drives the nut seat to move along the linear guide rail via the lead screw, thereby causing the infrared thermal imaging camera 403 fixed on the nut seat in the second linear module 402 to move in the Y direction, thereby performing a two-dimensional spatial scan above the steamer 1 to detect the temperature and escaping area inside the steamer 1. The specific structure of the first linear module 401 and the second linear module 402 can also be the overhead crane and synchronous belt drive linear assembly in the prior art, which are all prior art, and the specific working process will not be described in detail.

[0055] In this embodiment, the detection component 4 further includes a data processing module and a control module. The data processing module is electrically connected to the infrared thermal imaging camera 403 and is used to receive and analyze the temperature and escaping area data detected by the infrared thermal imaging camera 403. The control module is electrically connected to the data processing module, the first linear module, and the second linear module respectively. The infrared thermal imaging camera 403 detects the surface temperature of the steamer 1, distinguishes the escaping area, and then transmits the coordinates of the escaping area to the data processing module and the control module, thereby activating the robotic arm. The robotic arm moves the conveying component 2 and the spreading component 3 to the escaping area to spread the mash and prevent steam leakage. Through this combined movement of the first linear module 401, the second linear module 402, the infrared thermal imaging camera 403, the data processing module, and the control module, the camera covers different areas inside the steamer 1, thereby achieving comprehensive monitoring of temperature and escaping conditions.

[0056] Example 4

[0057] Based on Embodiment 1, Embodiment 2, or Embodiment 3, this utility model also provides a method for using the steaming device:

[0058] When the steaming device is working, the infrared thermal imaging camera 403, driven by the first linear module 401 and the second linear module 402, performs a two-dimensional spatial scan above the steaming barrel 1 to detect the temperature and escaping area inside the steaming barrel 1, and transmits the coordinate data of the escaping area to the data processing module. The data processing module analyzes and processes the data and transmits it to the control module. The control module starts the robotic arm according to the analysis results, and the robotic arm drives the conveying component 2 and the spreading component 3 to move to the escaping area to spread the mash.

[0059] Next, the control module starts the conveyor 202, which drives the drive roller 2022 to rotate via the drive device 203, causing the belt 2024 to circulate and transport the mash entering from the feed inlet 204 to the spreading assembly 3. The conveyor assembly 2 then transports the mash to the conical collection funnel 301, allowing it to enter the dispersing device 303. The first and second augers 3032 rotate via synchronous gears and a drive motor, dispersing the mash through staggered spiral blades to ensure... The mash is loose and uniform. After being broken up, it falls onto the transmission belt 304, which spreads the mash evenly into the steaming area inside the steam pot 1. When the robotic arm moves under the infrared thermal imaging camera 403, if it blocks the line of sight of the infrared thermal imaging camera 403, the first linear module 401 and the second linear module 402 automatically avoid the robotic arm's running trajectory through the data processing module and the control module, so that the infrared thermal imaging camera 403 can perform global detection of the surface temperature of the steam pot without blind spots.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
