Description

Technical Field

[0001] The utility model relates to the technical field of liquor brewing equipment, in particular to a liquor mash stacking and fermentation device. Background Art

[0002] In the production of Maotai-flavor liquor, the fermentation of mash by stacking is an essential and typical process. It plays a crucial role in developing the distinctive flavor of Maotai-flavor liquor, producing unique aroma and flavor compounds, and enhancing the quality and taste of the liquor. Traditional stacking fermentation relies heavily on manual labor, where workers gather the cooked mash into a round pile and subsequently stir it. This process often results in uneven fermentation, difficult microbial control, and low fermentation efficiency. Furthermore, it is labor-intensive and cannot guarantee the quality of the finished liquor.

[0003] Chinese patent document CN215667896U discloses a device for stacking and fermenting agarwood-type liquor mash, which includes a shell and an insulation layer. The insulation layer is provided on the inner side of the shell, a motor is provided on one side of the shell, a rotating shaft is provided at the output end of the motor, and a stirring blade is provided on one side of the rotating shaft. An inclined guide plate is provided inside the shell. When cooked grain enters the shell, the guide plate disperses it so that it can fall evenly inside the shell. After the grain is stacked, the motor is started to drive the rotating shaft to rotate, thereby driving the stirring blade to rotate. When the stirring blade rotates, the grain is distributed more evenly, without the need for manual operation, thereby improving convenience.

[0004] The utility model provides a white wine mash stacking fermentation device with another structure capable of improving the uniformity of the mash. Utility Model Content

[0005] The utility model aims to provide a device for piling and fermenting fermented mash of white wine, which improves the uniformity of the mash, shortens the fermentation time, and improves the quality of the finished white wine.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A device for stacking and fermenting white wine mash, comprising a box body and a box cover, wherein a fermentation cylinder is provided in the box body, the fermentation cylinder is a variable diameter structure with a top diameter larger than a bottom diameter, the top of the fermentation cylinder is fixedly connected to the four side walls of the box body, the bottom of the fermentation cylinder is fixedly connected to the bottom of the box body, the space between the side walls of the fermentation cylinder and the side walls of the box body is an air layer, a stirring mechanism is provided in the fermentation cylinder, the stirring mechanism comprises an auger and a motor, the bottom of the auger is rotatably connected to the bottom of the box body, the motor is fixedly arranged on the top of the box cover, the output end of the motor passes through the box cover and is detachably connected to the auger, and a heat dissipation device is provided in the air layer.

[0008] As a preferred technical solution, the box cover includes a horizontal plate and four inclined plates, the higher ends of the inclined plates are fixedly connected to the sides of the horizontal plate, and the inclined plates are a grid structure.

[0009] As an optimal technical solution, a dustproof cloth is fixedly provided on the top of the inclined plate, and the dustproof cloth completely covers the inclined plate.

[0010] As an optimal technical solution, the auger includes a spiral blade and a rotating shaft. The spiral blade is fixedly arranged on the outer surface of the rotating shaft.

[0024] Example

[0025] like Figure 1-2As shown, a device for stacking and fermenting white wine mash includes a box body 1 and a box cover. A fermentation cylinder 5 is provided in the box body 1. The fermentation cylinder 5 is a variable diameter structure with a top diameter larger than a bottom diameter. The top of the fermentation cylinder 5 is fixedly connected to the four side walls of the box body 1, and the bottom of the fermentation cylinder is fixedly connected to the bottom of the box body. The space between the side walls of the fermentation cylinder 5 and the side walls of the box body 1 is an air layer. A stirring mechanism is provided in the fermentation cylinder 5. The stirring mechanism includes an auger 6 and a motor 7. The bottom of the auger 6 is rotatably connected to the bottom of the box body 1. The motor 7 is fixedly arranged on the top of the box cover. The output end of the motor 7 passes through the box cover and is detachably connected to the auger 6. A heat dissipation device is also provided in the air layer.

[0026] It is worth noting that the fermentation drum 5 is used to pile up the steamed mash for fermentation, and the stirring mechanism is used to stir the mash to ensure the uniformity of the fermentation. The heat dissipation device is used to facilitate the adjustment of the fermentation temperature. Specifically, the variable diameter structure of the fermentation drum 5 ensures that the steamed mash is piled up less at the bottom and more at the top when it is piled up in the fermentation drum 5. The motor 7 drives the auger 6 to rotate and continuously bring the mash at the bottom to the top, which can enhance the uniformity of the mash and improve the uniformity of its temperature, humidity and oxygen distribution.

[0027] In some feasible embodiments, the box cover includes a horizontal plate 2 and four inclined plates 3. The higher ends of the inclined plates 3 are fixedly connected to the sides of the horizontal plate 2. The inclined plates 3 are a grid structure, so that the fermentation cylinder 5 can be connected to the external environment, allowing the mash to naturally absorb microorganisms in the air and reproduce, facilitating subsequent fermentation, while also ensuring the oxygen supply of the microorganisms.

[0028] In some feasible embodiments, a dustproof cloth 4 is fixed on the top of the inclined plate 3, and the dustproof cloth 4 completely covers the inclined plate 3 to prevent external dust or impurities from falling into the fermentation cylinder 5 and reducing the quality of the liquor.

[0029] In some feasible embodiments, the auger 6 includes a spiral blade and a rotating shaft. The spiral blade is fixedly mounted on the outer surface of the rotating shaft. A polygonal groove is formed on the top of the rotating shaft. A protrusion that matches the polygonal groove is provided on the output end of the motor 7. The output end of the motor 7 is detachably connected to the auger 6 through the matching polygonal groove and the protrusion. At the same time, the polygonal groove and the protrusion enable the motor 7 to drive the auger 6 to rotate.

[0030] In some feasible embodiments, the heat dissipation device includes a cooling fan 8 and a plurality of vents 9. The cooling fan 8 is embedded in the upper side wall of the housing 1, and the plurality of vents 9 are provided at the bottom of the housing 1, with the vents 9 being located outside the bottom of the fermentation cylinder 5. Air enters the space between the outer wall of the fermentation cylinder 5 and the inner wall of the housing 1 through the vents 9, and is then conveyed out of the housing 1 by the rotation of the cooling fan 8. The air flow removes heat, achieving rapid cooling.

[0031] In particular, when cooling is not required, the cooling fan 8 is turned off, and the air flow in the air layer slows down, so that the air layer has a good thermal insulation effect. Therefore, when the cooling fan 8 is not working, the air layer can form an insulation layer to maintain the fermentation temperature of the mash.

[0032] It should be noted that since the vent 9 is small, when the cooling fan 8 is turned off, the amount of air entering the air layer through the vent 9 is reduced, the air flow rate in the air layer slows down, and the heat carried away by the air is reduced, which can achieve the effect of heat preservation.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art. So far, the various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here. The scope of the present disclosure is defined by the appended claims.
