Description

Technical Field

[0001] This utility model relates to the field of automatic cooling machines, specifically to an automatic cooling machine for baijiu mash. Background Technology

[0002] The automatic cooling machine, a core piece of equipment in the baijiu brewing process, is mainly used to rapidly cool the cooked grain mash and mix it with yeast, laying the foundation for subsequent fermentation processes. This equipment typically consists of the cooling machine body, an internal chain conveyor belt, an external cooling fan, and an upper yeast-adding device. During operation, the cooling fan blows cold air through the side of the chain conveyor belt to cool the mash, while the yeast-adding device evenly sprays yeast onto the surface of the materials. The agitator above the chain conveyor belt is responsible for turning and mixing the materials.

[0003] In existing technologies, stirrers generally employ a linear stirring rod structure, which uses rotational motion to turn and mix the mash. However, the linear stirring rod has significant blind spots during rotation, resulting in uneven mixing of materials. In some areas, the yeast and mash cannot fully contact each other, leading to insufficient turning effect. This defect makes it difficult for cold air to fully penetrate the material layer, reducing cooling efficiency and affecting the uniform cooling of the mash and the distribution of yeast, ultimately adversely affecting the stability of the fermentation process and the quality of the liquor.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1-4 As shown in the embodiment of this application, an automatic cooling machine for baijiu mash is proposed, including a cooling machine body 1 and a chain conveyor belt 2 installed inside. Multiple cooling fans 3 for cooling are installed on the outside of the cooling machine body 1. A koji-adding device 4 is installed on the upper part of the chain conveyor belt 2. Multiple agitators 5 for turning and dispersing the mixture of materials and koji are installed on the upper part of the chain conveyor belt 2. The agitator 5 includes a rotating shaft 6 and multiple rows of L-shaped stirring rods 7. Each row of L-shaped stirring rods 7 is connected to a turning plate 8. A disperser is installed on the L-shaped stirring rods 7.

[0020] By optimizing the structure of the agitator 5, the problem of poor material mixing and turning effects caused by blind spots in the existing straight agitator bar was solved. Specifically, the L-shaped agitator bar 7 is designed to cut into the deep layers of the material at a specific angle, avoiding areas that traditional straight agitator bars cannot cover, thus effectively eliminating blind spots and enhancing material turning capabilities. Furthermore, the combination of the turning plate 8 and the L-shaped agitator bar 7 can simultaneously turn over and disperse the material during mixing, ensuring that the material is fully agitated during conveying and reducing dead-angle residue. Therefore, the overall structure, through the synergistic effect of the L-shaped design and additional components, significantly improves the mixing and turning effects of the material.

[0021] This application further proposes that the L-shaped stirring rod 7 and the rotating shaft 6 are arranged horizontally, and the rotating shaft 6 is driven by a drive motor installed on the outside of the cooling machine body 1. The lower part of the turning plate 8 is provided with multiple inserting saw teeth 9.

[0022] Specifically, the L-shaped stirring rod 7 refers to a stirring component with a right-angle bend structure, which can be made of metal. Its purpose is to expand the stirring coverage area through horizontal arrangement, avoiding blind spots in material mixing. The rotating shaft 6 can be understood as the core component for transmitting rotational power. It can be connected to the output shaft of the drive motor via a keyway connection or interference fit, ensuring the stability of power transmission. The serrations 9 at the bottom of the tipping plate 8 are a material-inserting structure with sharp edges. They can be fixed to the tipping plate by welding or integral molding, aiming to enhance the material gripping ability.

[0023] In detail, this technical solution arranges the L-shaped stirring rod 7 and the rotating shaft 6 horizontally, allowing the stirring rod to sweep the material surface more comprehensively during rotation, effectively avoiding the dead corners that may occur with traditional inclined arrangements. The serrations 9 at the bottom of the turning plate 8 penetrate deep into the material layer during turning, preventing material slippage or accumulation, and making it easier to thoroughly turn and disperse the material. This structural design not only improves the uniformity of material mixing but also promotes full contact between the cold air and the material, thereby improving the cooling effect and the mixing quality of the yeast. Furthermore, this solution, in conjunction with the chain conveyor belt 2, cooling fan 3, and other basic structures, further optimizes the overall performance of the cooling machine.

[0024] This application further proposes a dispersant including a plurality of dispersing rods 10 arranged perpendicularly to the L-shaped stirring rod 7, wherein the plurality of dispersing rods 10 are connected to a rotating sleeve 11 sleeved on the L-shaped stirring rod 7.

[0025] This technical solution achieves multi-directional material dispersion through the cooperation of multiple dispersing rods 10 and a rotating sleeve 11. The dispersing rods 10 are arranged perpendicular to the L-shaped stirring rod 7, allowing them to cut into the material from different directions as the L-shaped stirring rod 7 rotates, effectively dispersing clumps. The rotating sleeve 11 design enables the dispersing rods 10 to have adaptive rotation capabilities, flexibly adjusting their angle when encountering material resistance to ensure continuous and effective dispersion. This design fully utilizes the rotational kinetic energy of the L-shaped stirring rod 7, converting linear stirring motion into multi-directional dispersion force, which not only improves the mixing uniformity of the material and the yeast but also optimizes the contact area with the cold air. Simultaneously, this solution, combined with the structural characteristics of the L-shaped stirring rod 7, forms a more efficient material handling system, significantly improving material mixing and cooling efficiency.

[0026] This application further proposes that the rotating sleeve 11 is set at the tail of the turning plate 8, and a limiting rod 12 is fixed on the L-shaped stirring rod 7 to restrict the movement of the rotating sleeve 11.

[0027] By precisely positioning the rotating sleeve 11 at the tail of the tipping plate 8 and axially constraining it with the limiting rod 12, the potential axial movement of the rotating sleeve 11 during operation is effectively solved. The choice of positioning the rotating sleeve 11 at the tail of the tipping plate 8 intervenes during the critical stage of material falling after being tipped over, allowing the dispersing rod 10 to specifically handle areas prone to material accumulation. Simultaneously, the limiting rod 12 physically constrains the rotating sleeve 11 to prevent axial movement due to equipment vibration or material resistance, ensuring the dispersing rod 10 remains in an optimized position. Combined with the arrangement of the L-shaped stirring rods 7, this structural design better adapts to material flow characteristics, reduces mixing blind spots, and improves overall mixing efficiency.

[0028] This application further proposes that the front end of the cooling machine body 1 is provided with a feeding hopper 13, and multiple fans 14 are provided on the outside of the feeding hopper 13. The outlet of the fans 14 is connected to the cavity 15 provided inside the feeding hopper 13, and multiple cooling air holes 16 are provided on the outside of the cavity 15.

[0029] A pre-cooling mechanism is introduced during the feeding stage to effectively reduce the initial temperature of the mash, laying a uniform cooling foundation for the subsequent cooling and mixing processes. A feeding hopper 13 is located at the front end of the cooler body 1 as the mash input channel, ensuring orderly material entry into the equipment. Multiple fans 14 are installed outside the feeding hopper 13 to provide a stable airflow source. The layout of multiple fans 14 enhances the cooling coverage and improves the airflow supply capacity. The design of connecting the fan outlets 14 to the internal cavity 15 of the feeding hopper 13 allows the airflow to be buffered and diffused within the cavity 15, avoiding direct impact on the mash and preventing material splashing or localized disturbance. Multiple cooling air holes 16 are located outside the cavity 15 to transform the diffused airflow into a fine airflow beam, evenly blowing on the surface of the mash, achieving a gentle and comprehensive pre-cooling effect. This prevents mixing blind spots caused by sudden temperature changes or localized overheating, ultimately improving the overall uniformity and efficiency of the cooling process. Furthermore, this solution, in conjunction with the chain conveyor belt 2, cooling fans 3, and other structures, can better achieve the overall cooling effect.

[0030] This application further proposes a yeast addition device 4, which includes a yeast tank connected to a spray pipe located at the bottom via a connecting hose.

[0031] The yeast tank, serving as a storage unit, is connected to the spray pipe via a flexible hose. This flexible connection method is particularly suitable for the dynamic working environment of the chain conveyor belt 2, avoiding the defects of rigid pipes that are prone to breakage. The spray pipe is located at the bottom, directly facing the material layer on the chain conveyor belt 2, allowing the yeast to be evenly distributed, expanding the coverage area and preventing concentrated accumulation. This bottom spray design, combined with the turning action of the agitator 5, enables the yeast to be initially dispersed before the material is turned, significantly reducing mixing blind spots and promoting full integration of the yeast and material, laying a uniform foundation for subsequent cooling and fermentation.

[0032] Through the above technical solution, the yeast is added evenly in the automatic cooling machine. Combined with the turning action of the stirrer 5, the mixing efficiency of the material and the yeast is effectively improved, the mixing blind zone is reduced, and thus the cooling uniformity and subsequent fermentation quality are improved.

[0033] The implementation principle of the automatic cooling machine for baijiu mash in this application embodiment is as follows:

[0034] The cooling machine body 1 and the internal chain conveyor belt 2 together form the basic platform for material conveying, providing a stable operating environment for cooling and mixing the mash. Multiple cooling fans 3 installed on the outside of the cooling machine body 1 achieve rapid cooling of the mash by blowing air, while the yeast-adding device 4 installed on the upper part of the chain conveyor belt 2 completes the addition of yeast. These basic structures ensure that the basic conditions of the process are met.

[0035] Multiple agitators 5 mounted on the upper part of the chain conveyor belt 2 are specifically designed for turning and dispersing materials, directly addressing the problem of uneven material mixing. Each agitator 5 includes a rotating shaft 6 and multiple rows of L-shaped agitator bars 7. The unique angled shape of the L-shaped agitator bars 7 allows them to cut into the deeper layers of the material at a specific angle during rotation, avoiding areas that traditional straight agitator bars cannot cover, thus effectively eliminating blind spots and enhancing the turning capability. Each row of L-shaped agitator bars 7 is connected to a turning plate 8 that simultaneously turns and disperses the material with the agitation action, ensuring that the material is fully agitated during conveying and reducing dead-angle residue. Furthermore, a disperser installed on the L-shaped agitator bars 7 can break up clumps in the material in real time, promoting uniform mixing of the yeast and mash. Therefore, through the synergistic effect of the L-shaped agitator bars 7, the turning plate 8, and the disperser, the overall technical solution significantly improves the mixing and turning effect of the material, solving the blind spot problem caused by design flaws in the agitator bars in existing automatic cooling machines.
