Description

Technical Field

[0001] The utility model relates to the technical field of liquor brewing, in particular to a saccharification pile oxygenation device. Background Art

[0002] The fermentation process of Maotai-flavor liquor is divided into two main stages: aerobic fermentation and anaerobic fermentation.

[0003] Aerobic fermentation occurs after the brewing raw materials are steamed. The steamed grains are piled up to form a round pile. This process is called "stacking". During the stacking process, microorganisms become active, especially yeast and mold, which will respire in an aerobic environment, decompose the sugar in the grain, and produce heat and various organic acids and other substances. This process is accompanied by an increase in temperature, which can reach 50°C to 53°C, and sometimes even higher. This high-temperature aerobic environment is conducive to the production of the unique sauce-flavor substances of Maotai-flavor liquor, laying the foundation for subsequent anaerobic fermentation. It is also one of the key steps in the formation of the unique style of Maotai-flavor liquor.

[0004] Anaerobic fermentation occurs after the pile fermentation reaches a certain stage. Usually, when the temperature and microbial activity reach the predetermined indicators, the fermented material will be transferred to the cellar for anaerobic fermentation. At this stage, the environment changes to low oxygen or anaerobic, and yeast begins alcohol fermentation in the absence of oxygen, converting sugar into alcohol and carbon dioxide. In the cellar, the fermented material undergoes a series of complex microbial metabolism. This step not only produces alcohol, but also produces more complex flavor substances, further enriching the aroma and taste of the wine.

[0005] However, during the pile fermentation process of traditional Maotai-flavor liquor, due to the large volume of the saccharification pile and the high viscosity of the mash in the later stage, the dissolved oxygen at the bottom and center of the pile is poor during the fermentation process, resulting in a low temperature and low oxygen content in the center of the pile, which in turn leads to insufficient fermentation and a less prominent Maotai flavor. Utility Model Content

[0006] In order to solve the technical problem that the oxygen content in the core and bottom of the existing saccharification pile is low, resulting in insufficient fermentation and insufficient sauce aroma, the utility model provides a saccharification pile oxygenation device with a simple structure and the ability to increase the oxygen content in the core and bottom of the pile.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] The saccharification pile oxygenation device includes a riser and a coil. The riser is vertically arranged, and the top and bottom ends of the riser are sealed. A plurality of exhaust holes penetrating the inner wall and the outer wall are opened on the periphery of the riser. A connecting hole penetrating the inner wall and the outer wall is opened at the bottom of the riser. The coil pipe mouth is sealed and connected to the connecting hole. The coil is horizontally wound around the riser. A plurality of ventilation holes penetrating the inner wall and the outer wall are opened on the periphery of the coil. The device also includes a gas supply device and a gas transmission pipe. The gas inlet at one end of the gas transmission pipe is connected to the gas supply device, and the other end is connected to the pipe mouth of the outermost circle of the coil.

[0009] Furthermore, the lowermost end of the riser is higher than the bottom of the coil, and the coil is used to support the riser.

[0010] Furthermore, the riser includes two sections of pipes, namely the first section of pipe and the second section of pipe from bottom to top, the length of the first section of pipe is 0.2-0.8 times the length of the second section of pipe, the inner diameter of the first section of pipe is 2-5 times the inner diameter of the second section of pipe, and the number of exhaust holes of the first section of pipe is greater than the number of exhaust holes of the second section of pipe.

[0011] Furthermore, the opening density of the exhaust holes of the first section of the tube and the second section of the tube is the same.

[0012] Furthermore, the inner diameter of the second section of the pipe is equal to the inner diameter of the coiled pipe.

[0013] Furthermore, the opening density of the ventilation holes is 0.2-0.8 times the opening density of the exhaust holes.

[0014] Furthermore, the diameter of the vent hole is 5mm-7mm, the center distance between two adjacent vent holes is 15mm-17mm, the diameter of the exhaust hole is 5mm-6.5mm, and the center distance between two adjacent exhaust holes is 7mm-9mm.

[0015] Furthermore, the gas pipe is connected to the coil by a snap-fit ​​connection.

[0016] Furthermore, the air supply device is a hair dryer that generates cold and hot air alternately.

[0017] The beneficial effects of the utility model are:

[0018] 1. Standpipe and coil structure: A three-dimensional oxygen supply layout is achieved by setting the standpipe vertically and equipping it with multiple layers of coils wound horizontally. The coil acts as a gas channel to efficiently introduce gas into the standpipe. The upper and lower ends of the standpipe are sealed. The exhaust holes on the standpipe can effectively guide the gas to the core of the saccharification pile, which helps to increase the oxygen content in the core area. The coil is located at the bottom of the saccharification pile. The vents of the coil help to increase the oxygen content in the bottom area, solving the problem of low oxygen content in the core and bottom of the pile in traditional processes, promoting aerobic respiration of microorganisms, and improving fermentation efficiency and the generation of sauce-flavored substances.

[0019] 2. The lowest end of the riser is higher than the bottom of the coil. The coil is used to support the riser. The coil can not only transport oxygen to the bottom of the pile, but also provide support for the riser. The coil is in contact with the ground and acts as a base.

[0020] 3. Segmented riser design: The different lengths and inner diameter ratios of the first and second sections of the pipe can more accurately control the gas flow path and pressure distribution. The number of exhaust holes in the first section of the pipe is greater than that in the second section of the pipe, so that the core of the saccharification pile can obtain sufficient oxygen supply. The larger first section of the pipe is located at the core of the pile, and the large inner diameter helps to provide sufficient gas flow, so that the air is gathered in the core of the pile as much as possible and then diffused from the core to the surrounding areas.

[0021] 4. Consistent opening density: The opening density of the exhaust holes in the first section of the tube is the same as that of the exhaust holes in the second section of the tube. On the one hand, it simplifies the difficulty of production and manufacturing. On the other hand, the same opening density ensures the balanced distribution of oxygen at different depths and ranges, which not only avoids the temperature runaway caused by local excess oxygen, affecting the fermentation efficiency and fermentation effect, but also ensures that the oxygen demand inside the entire saccharification pile is met.

[0022] 5. Matching pipe diameter size: The second section of the pipe is designed to have an inner diameter equal to that of the coil. This design is based on the distribution of materials in the saccharification pile, and solves the problem of oxygen distribution to a certain extent. The gas passes through the small-diameter coil, then to the large-diameter first section of the pipe, and then to the second section of the pipe with the same diameter as the coil. The gas undergoes a process from compression to expansion and then to compression again, ensuring that the gas outflow is the largest at the first section of the pipe, that is, the gas outflow is the largest at the core of the pile.

[0023] 6. The opening density of the ventilation holes is 0.2-0.8 times that of the exhaust holes. The saccharification pile mainly has a greater demand for oxygen in the core. The opening density of the ventilation holes is smaller to avoid local excess oxygen and affect the fermentation efficiency and effect. This design ensures a balanced oxygen distribution in various parts of the saccharification pile.

[0024] 7. Accurately set the diameter and spacing of the vent holes and exhaust holes. The pore spacing control can control the number of holes in the riser and coil, and accurately control the outflow of gas, so as to control the appropriate oxygen concentration inside the saccharification pile, promote microbial activity and the full generation of sauce-flavored substances. The diameter design of the vent holes and exhaust holes can not only ensure the appropriate oxygen discharge flow, but also avoid the opening diameter being too large, so that the mash in the saccharification pile enters the pipeline and causes pipeline blockage.

[0025] 8. Convenient connection method: The gas pipe and the coil are connected by snap-fit, which is convenient for installation and maintenance, ensuring air tightness while improving the practicality of the device.

[0026] 9. Flexibility of gas supply equipment: Using a hair dryer that alternately generates hot and cold air as the gas supply equipment can flexibly adjust the gas supply strategy according to the changes in the temperature of the saccharification pile during the fermentation process. It can not only adjust the pile temperature, but also promote microbial activity by alternating hot and cold air, further optimize the fermentation conditions, and improve the quality and flavor of the sauce-flavor liquor.

[0027] In summary, the saccharification pile oxygenation device significantly improves the oxygen content in the central and bottom areas of the saccharification pile through the above-mentioned structural design, optimizes the fermentation conditions, promotes the full progress of aerobic fermentation, solves the problems of insufficient fermentation and insufficient sauce aroma in traditional brewing technology, and provides an effective technical means for brewing high-quality sauce-flavor liquor.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Reference Figure 1 to Figure 2 The utility model provides a saccharification pile oxygenation device.

[0036] In some embodiments, the saccharification pile oxygenation device includes a riser and a coil 4, the riser is vertically arranged, the top and bottom of the riser are sealed, a plurality of exhaust holes penetrating the inner wall and the outer wall are opened on the periphery of the riser, a connecting hole penetrating the inner wall and the outer wall is opened on the side wall at the bottom end of the riser, the pipe mouth of the coil 4 is sealed and connected to the connecting hole, the coil 4 is horizontally wound around the riser, a plurality of ventilation holes penetrating the inner wall and the outer wall are opened on the periphery of the coil 4, and also includes a gas supply device 4 and a gas transmission pipe 3, the gas inlet 9 at one end of the gas transmission pipe 3 is connected to the gas supply device 1, and the other end is connected to the pipe mouth of the outermost circle of the coil 4.

[0037] Regarding the horizontal winding of the coil 4 around the riser, adjacent turns of the coil 4 may have a certain gap or may fit tightly together, which is not particularly limited here. In this solution, it is preferred that adjacent turns of the coil 4 have a certain gap between them, as such a design can save material usage.

[0038] Regarding the connection between the coil 4 and the vertical pipe, the lowest end of the vertical pipe can be higher than the bottom of the coil 4, in which case the coil 4 contacts the ground, and the coil 4 can support the vertical pipe; the lowest end of the vertical pipe can also be lower than the bottom of the coil 4, in which case the vertical pipe contacts the ground. When using this device, the device can be fixed by hand or other supporting parts, and then the mash can be piled on this device for fermentation. Whether the vertical pipe contacts the ground or the coil 4 contacts the ground is not particularly limited here.

[0039] The connection hole opened at the bottom end of the riser may be opened at the pipe opening sealing position at the bottom end of the riser, or may be opened at the side wall at the bottom end of the riser.

[0040] The top and bottom ends of the riser are designed to be sealed. The top and bottom ends of the riser may be integrally formed with the side of the riser, or a sealing sheet 7 may be provided for sealing.

[0041] The connection between the gas transmission pipe and the coil can be fixed by welding or by detachable fixing, such as snap fixing, bolt fixing, etc.

[0042] In some embodiments, the riser includes two sections of pipes, namely, a first section of pipe 5 and a second section of pipe 6 from bottom to top. The length of the first section of pipe 5 is 0.2-0.8 times the length of the second section of pipe 6. The inner diameter of the first section of pipe 5 is 2-5 times the inner diameter of the second section of pipe 6. The number of exhaust holes in the first section of pipe 5 is greater than the number of exhaust holes in the second section of pipe 6.

[0043] The length of the first section of the tube 5 is 0.2-0.8 times the length of the second section of the tube 6, and the inner diameter of the first section of the tube 5 is 2-5 times the inner diameter of the second section of the tube 6. The reason why the number of exhaust holes in the first section of the tube 5 is greater than that in the second section of the tube 6 is to take into account the position of the core of the saccharification pile 2, so that the core position can obtain sufficient oxygen, while the oxygen supply at the position far from the core will be reduced accordingly. This is to avoid the possible temperature runaway when the oxygen is too sufficient, affecting the fermentation efficiency and fermentation effect. These dimensions are only preferred. Designs that are not within this size range can also supply oxygen to the saccharification pile 2, but the fermentation effect and fermentation efficiency are reduced compared with the preferred embodiment.

[0044] In some embodiments, the first section of the tube 5 and the second section of the tube 6 have the same opening density of the exhaust holes. It is a preferred embodiment to make the opening density of the first section of the tube 5 and the second section of the tube 6 the same. The above embodiments do not require the same opening density, but only require different numbers of openings. Here, the opening density is designed to be the same, which is convenient for production and manufacturing on the one hand, and makes the oxygen supply more balanced on the other hand, and also ensures that the opening amount of the first section of the tube 5 is greater than the opening amount of the second section of the tube 6.

[0045] In some embodiments, the inner diameter of the second section of pipe 6 is equal to the inner diameter of the coiled pipe 4 .

[0046] In some embodiments, the opening density of the ventilation holes is 0.2-0.8 times the opening density of the exhaust holes. Here, the opening density of the coil 4 is further limited, and the number of openings is further limited. The saccharification pile 2 mainly has a greater demand for oxygen in the core, and the opening density of the ventilation holes is small to avoid local excess oxygen, which affects the fermentation efficiency and effect. Such a design makes the oxygen distribution of each part of the saccharification pile 2 balanced, increasing the fermentation efficiency and fermentation effect.

[0047] In some embodiments, the diameter of the vent hole is 5mm-7mm, and the center distance between two adjacent vent holes is 15mm-17mm. The diameter of the exhaust hole is 5mm-6.5mm, and the center distance between two adjacent exhaust holes is 7mm-9mm. The diameter design of the vent hole and the exhaust hole here can ensure a suitable oxygen discharge flow rate, and can also avoid the opening diameter being too large, so that the mash in the saccharification pile 2 enters the pipeline and causes pipeline blockage. The above embodiments do not limit the diameter of the vent hole and the exhaust hole, but those skilled in the art should be aware that the opening size cannot be too large, causing the mash to block the pipeline.

[0048] In some embodiments, the gas pipe 3 and the coil 4 are connected by a buckle 8. The buckle 8 is used to connect the gas pipe 3 and the coil 4, which is convenient for installation and maintenance, ensures air tightness and improves the practicality of the device.

[0049] In some embodiments, the gas supply device 1 is a hair dryer that alternately generates hot and cold air. The aforementioned embodiments do not limit the type and temperature of air supply of the gas supply device 1, whether it is cold air or hot air, but those skilled in the art should be aware that the gas introduced should be the conventional temperature airflow used by those skilled in the art in fermentation of mash. This embodiment designs the supply of alternating hot and cold airflows, and can flexibly adjust the gas supply strategy according to the change of the temperature of the saccharification pile 2 during the fermentation process, which can not only adjust the pile temperature, but also promote microbial activity through alternating hot and cold air, further optimize the fermentation conditions, and improve the quality and flavor of the sauce-flavored liquor.
