Description

Technical Field

[0001] The present invention relates to the technical field of liquor brewing, and in particular to a segmented intelligent airing system and an operating method thereof. Background Art

[0002] In the current liquor brewing process, the drying process of the fermented grains is particularly important, especially in the production process of Luzhou-flavor liquor. After a period of solid-state fermentation, the fermented grains will be mixed with a certain proportion of new grains and rice husks, and then distilled by "mixed steaming and mixed burning". After the fermented grains are steamed, in order to ensure that the subsequent addition of koji and the fermentation process in the pool can proceed smoothly, the temperature of the fermented grains needs to be cooled down in time. The traditional drying process is generally carried out in a single drying method, that is, the fermented grains in a high temperature state after cooking are directly transported to the drying bin through a conveyor belt for cooling. The drying bin is mostly composed of multiple blowers arranged on both sides of the conveyor belt, as well as an exhaust device fixed on the top of the wind collecting bucket and a roller stirring device. This type of drying method not only has the problem of uneven stirring, but also the drying temperature is easily affected by the ambient temperature. There is a significant local temperature difference during the drying process, and the drying temperature cannot be controlled. Especially in summer, due to the high natural temperature, it is difficult to effectively reduce the temperature of the fermented mash during drying, which will greatly affect the yield and quality of the original wine. Therefore, how to avoid the problem of significant local temperature difference during the drying of the fermented mash, ensure that the fermented mash can be cooled evenly, and improve its cooling efficiency, so that the drying temperature is within a controllable range and avoid being affected by the natural temperature is a problem that people in this field need to solve.

[0033] On the other hand, the operation method of the segmented intelligent drying system includes the following steps:

[0034] After the fermented grains are cooked, they are poured into the wine tank mobile overturn unloader, and then transferred to the drying feeder 10 of the segmented intelligent drying system;

[0035] The drying feeder 10 transports the fermented grains to the conveyor belt 20, and the fermented grains enter the primary cooling bin 31 of the cooling device 30 for cooling. The first blower 313 in the primary cooling bin 31 cools the fermented grains, and the hot air blown out is extracted by the exhaust device 40 at the top.

[0037] The fermented grains cooled in the secondary cooling bin 32 are transferred to the tertiary cooling bin 33 for cooling. The third blower 333 connected to the tertiary cooling bin 33 blows cold air to cool the fermented grains under the action of the cold air system 50, and the second blower 323 pumps the air after heat exchange in the third cooling bin 33 through the ventilation duct 301 and transfers it to the secondary cooling bin 32 for recycling.

[0038] After the drying is completed, the infrared temperature sensing element 302 detects the temperature of the mash. When the detected temperature is higher or lower than the set temperature range, timely feedback is issued to adjust the subsequent drying operation. The mash is then conveyed to the koji adding bin 60 via the conveyor belt conveyor 20 for adding koji and stirring.

[0039] Specifically, the present embodiment adopts three-stage cooling, that is, the fermented grains are cooled and cooled in sequence through the first-stage cooling bin 31, the second-stage cooling bin 32 and the third-stage cooling bin 33, which not only increases the number of cooling bins and prolongs the drying process compared to the traditional airing equipment, but also enables the fermented grains to be graded and cooled, thereby improving the cooling efficiency. Furthermore, the second-stage cooling bin 32 and the third-stage cooling bin 33 are interconnected, and the first-stage cooling bin 31 and the second-stage cooling bin 32 are both connected to the exhaust device 40, which not only enables the cooling air in the third-stage cooling bin 33 to be recovered and reused, thereby improving the cooling effect of the fermented grains in the second-stage cooling bin 32, but also enables the heat-exchanged air to be pumped out in time through the exhaust device 40, thereby ensuring the cooling state of the fermented grains, thereby enabling the fermented grains to be quickly cooled to the target temperature. At the same time, the three-stage cooling bin 33 is connected to the cold air system 50, and the air in the three-stage cooling bin 33 can be quickly cooled down under the action of the cold air system 50, and the cooling effect of the fermented grains can be ensured in the summer when the natural temperature is high, so that it is not easily affected by the surrounding environment, and the quality of the subsequent raw wine is guaranteed. Furthermore, the koji adding bin 60 can set the amount of koji added according to the feeding rate of the drying feeder 10 and the operating rate of the conveyor mesh belt machine 20, so that the process of adding koji is more scientific and reasonable, and its accuracy is higher.

Further, the exhaust device 40 and the cold air system 50 are both connected to the cooling device 30, and the exhaust device 40 can extract the hot air blown by the fermented mash, and the cold air system 50 can cool the air inside the cooling device 30, so as to ensure the stability and uniformity of the fermented mash airing, avoid the problem of significant local temperature difference in the airing process in the prior art, and thus ensure the yield and quality of the original wine.

[0042] like Figure 1As shown, in this embodiment, a belt scale 101 is provided at the bottom of the airing feeder 10. Specifically, in this embodiment, the belt scale 101 is used to weigh the fermented mash, and can feed back the data such as the feeding situation to the koji adding bin 60 in real time, so that the amount of koji added can be controlled to ensure product quality. Further, in this embodiment, a feedback element 601 is provided at the koji adding bin 60, and the feedback element 601 can set a lag time according to the operating speed and transmission frequency fed back by the conveyor mesh belt machine 20, and according to the data such as the feeding rate fed back by the belt scale 101, the amount of koji added to the fermented mash after cooling can be adjusted in time and dynamically, so that the amount of koji added can be controlled. Accordingly, the lag time when the conveyor mesh belt machine 20 is running can also be set accordingly according to the feeding situation fed back by the belt scale 101, so that the amount of koji added to the koji adding bin 60 can be controlled according to the koji adding ratio set by the process standard under the action of the feedback element 601, so that the koji adding process is more scientific and reasonable, and the accuracy of its operation is improved.

[0043] Combination Figure 1-Figure 3 As shown, in this embodiment, the cooling device 30 is arranged on the conveyor belt machine 20, and the cooling device 30 at least includes a first-level cooling bin 31, a second-level cooling bin 32 and a third-level cooling bin 33 arranged in sequence. Optionally, in this embodiment, the first-level cooling bin 31 and the second-level cooling bin 32 are both connected to the exhaust device 40, so that the hot air of the fermented grains can be sucked out and the cooling of the fermented grains can be accelerated. Further, the third-level cooling bin 33 is connected to the cold air system 50, and the third-level cooling bin 33 and the second-level cooling bin 32 are interconnected, so that the cold air system 50 can control the temperature in the third-level cooling bin 33, and the cold air in the subsequent third-level cooling bin 33 can continue to be recycled into the second-level cooling bin 32, so as to achieve recycling and improve the drying efficiency. Accordingly, it can also solve the problem that the natural temperature in summer is too high, the temperature of the fermented grains is difficult to drop, and it can never drop to the target temperature.

[0044] Furthermore, in this embodiment, the cooling device 30 is also provided with a ventilation duct 301 and an infrared temperature sensing element 302, wherein the two ends of the ventilation duct 301 are respectively connected to the inside of the secondary cooling bin 32 and the tertiary cooling bin 33, so as to ensure that the cold air in the tertiary cooling bin 33 can be recycled by the secondary cooling bin 32, thereby ensuring the cooling effect and cooling efficiency of the mash. Furthermore, the infrared temperature sensing element 302 is arranged on the side of the tertiary cooling bin 33 away from the secondary cooling bin 32, and can detect the temperature of the mash after cooling, so as to compare the detected temperature with the set range, and when the detected temperature is higher or lower than the set temperature range, feedback can be given in time, and the equipment can adjust the spreading process in time according to the feedback, so that the spreading temperature is controlled within the set range, and the corresponding control means belong to the technical means commonly used by people in this field, which will not be described here.

[0045] like Figure 2 As shown, in this embodiment, the first cooling bin 31 is provided with a first air collecting hopper 311, a first mixer 312 and a first blower 313. Specifically, the first air collecting hopper 311 is covered on the mash of the conveyor mesh belt machine 20 and is arranged close to the airing feeder 10. Further, the top of the first air collecting hopper 311 is connected to the exhaust device 40, and the bottom thereof is connected to the first blower 313, so that the first blower 313 can provide a blowing operation in the first air collecting hopper 311 to accelerate the cooling effect of the mash, and the hot air blown out can be pumped and discharged from the exhaust device 40 at the top. Further, at least three first mixers 312 are provided, and are arranged at intervals, and are located inside the first air collecting hopper 311 for stirring the mash, so as to cooperate with the stirring operation of the first mixer 312 on the mash and the blowing operation of the first blower 313, so that the mash can be quickly cooled in the first air collecting hopper 311. For example, in this embodiment, at least four first blowers 313 are provided, and the four first blowers 313 are all provided on the same side of the conveyor mesh belt machine 20. In other embodiments, the placement positions thereof can be set as required to ensure the blowing effect. Accordingly, in this embodiment, the first-level cooling bin 31 can cool the brewed mash transported by the airing feeder 10 to 40°C-45°C. Thus, the first-level cooling bin 31 can cool the brewed mash to the first target temperature by using natural wind.

[0046] like Figure 3 As shown, in this embodiment, the secondary cooling bin 32 is arranged between the primary cooling bin 31 and the tertiary cooling bin 33, and is provided with a second air collecting scoop 321, a second mixer 322, and a second blower 323. Specifically, the second air collecting scoop 321 is covered on the mash of the conveyor belt 20, and the top of the second air collecting scoop 321 is connected to the exhaust device 40, and the second blower 323 is connected to the ventilation duct 301, so as to be able to pump the air in the tertiary cooling bin 33 to the second air collecting scoop 321, thereby accelerating the cooling effect of the mash, and the hot air blown out can be pumped out from the exhaust device 40 at the top. Further, at least three second mixers 322 are provided, and are arranged at intervals, and are located inside the second air collecting scoop 321 for stirring the mash, so as to cooperate with the stirring operation of the second mixer 322 on the mash and the blowing operation of the second blower 323, so that the mash can be quickly cooled in the second air collecting scoop 321. For example, in this embodiment, at least six second blowers 323 are provided, and the six second blowers 323 are all provided on the same side of the conveyor belt conveyor 20. In other embodiments, the placement positions thereof can also be set as required. Further, the secondary cooling bin 32 can cool the mash to room temperature and reach the second target temperature.

[0047] like Figure 3As shown, in this embodiment, the third-stage cooling bin 33 is arranged at one end close to the song adding bin 60, and is provided with a third air collecting scoop 331, a third mixer 332 and a third blower 333. Optionally, the third air collecting scoop 331 is covered on the conveyor belt 20, and the bottom of the third air collecting scoop 331 is connected to the third blower 333, the third blower 333 is connected to the cold air system 50, and the interior of the third air collecting scoop 331 is connected to the secondary cooling bin 32 through the ventilation duct 301, so that under the action of the third blower 333, the third air collecting scoop 331 can be provided with a blowing operation, and the third blower 333 can blow out cold air through the cold air system 50, so that the internal temperature of the third air collecting scoop 331 can be quickly reduced to accelerate the cooling effect of the mash, and at the same time, the heat-exchanged air can be returned to the secondary cooling bin 32 under the pumping action of the second blower 323 in the ventilation duct 301 to achieve a recovery effect, and the mash in the secondary cooling bin 32 can be cooled again, so as to achieve energy recovery and improve cooling efficiency. Further, in this embodiment, at least three third stirrers 332 are provided, and are arranged at intervals, and are located in the third air collecting hopper 331 for stirring the fermented grains, so as to cooperate with the stirring operation of the third stirrer 332 on the fermented grains and the blowing operation of the third blower 333, so that the fermented grains can be quickly cooled in the third air collecting hopper 331. Exemplarily, in this embodiment, at least six third blowers 333 are provided, and the three-stage cooling bin 33 can cool the fermented grains to 12°C-14°C. Optionally, the three-stage cooling bin 33 can control the temperature of the cooling air blown out by the third blower 333 to about 10°C through the cold air system 50, thereby cooling the fermented grains to the third target temperature, and by controlling the relevant parameters of the cold air system 50, the cooling temperature inside it can also be adjusted. Since the cooling device 30 in this embodiment cools the fermented grains in stages, the value of the first target temperature is greater than the value of the second target temperature, and the value of the second target temperature is greater than the value of the third target temperature.

[0048] like Figure 1As shown, in this embodiment, the exhaust device 40 is connected to the top of the first wind collecting scoop 311 and the top of the second wind collecting scoop 321 through two pipes, so that the hot air inside can be pumped out, thereby improving the cooling efficiency of the fermented grains. Furthermore, the cold air system 50 is provided with a condensing water pipe and a heat exchange device, and in this embodiment, cooling water at 8°C-9°C circulates in the condensing water pipe, so that the air temperature in the third wind collecting scoop 331 in the third cooling bin 33 can be adjusted under the interaction of the condensing water pipe and the heat exchange device, so that it can be cooled quickly, so as to achieve rapid cooling of the fermented grains in the third cooling bin 33 when the ambient temperature is high in summer, and thereby make the temperature inside the cooling device 30 adjustable. Correspondingly, in this embodiment, the cold air system 50 is connected to the third blower 333, so that the third blower 333 can blow out cold air through the cold air system 50, thereby quickly cooling the inside of the third air collecting scoop 331. That is, the temperature of the cooling air blown out by the third blower 333 can be controlled by adjusting the temperature and flow rate of the circulating water in the cold air system 50, thereby achieving the purpose of controlling the cooling temperature of the mash.

[0049] The operating method of the segmented intelligent drying system in this embodiment is described in detail below.

[0050] The operating method of the segmented intelligent drying system comprises the following steps:

[0051] After the fermented grains are cooked, they are poured into the wine tank mobile overturn unloader, and then transferred to the drying feeder 10 of the segmented intelligent drying system;

[0052] The drying feeder 10 transports the fermented grains to the conveyor belt 20, and the fermented grains enter the primary cooling bin 31 of the cooling device 30 for cooling. The first blower 313 in the primary cooling bin 31 cools the fermented grains, and the hot air blown out is extracted by the exhaust device 40 at the top.

[0053] The fermented grains cooled in the primary cooling bin 31 are transferred to the secondary cooling bin 32 for cooling. The second blower 323 in the secondary cooling bin 32 cools the fermented grains, and the hot air blown out is also extracted by the exhaust device 40 at the top.

[0054] The fermented grains cooled in the secondary cooling bin 32 are transferred to the tertiary cooling bin 33 for cooling. The third blower 333 connected to the tertiary cooling bin 33 blows cold air to cool the fermented grains under the action of the cold air system 50, and the second blower 323 pumps the air after heat exchange in the third cooling bin 33 through the ventilation duct 301 and transfers it to the secondary cooling bin 32 for recycling.

[0055] After the drying is completed, the infrared temperature sensing element 302 detects the temperature of the mash. When the detected temperature is higher or lower than the set temperature range, timely feedback is issued to adjust the subsequent drying operation. The mash is then conveyed to the koji adding bin 60 via the conveyor belt conveyor 20 for adding koji and stirring.

[0056] Specifically, after the fermented grains are boiled in this embodiment, they are transported to the cooling device 30 through the airing feeder 10, and then the temperature of the fermented grains is rapidly reduced to the target temperature by the three-stage cooling effect of the cooling device 30. At the same time, the koji adding bin 60 in the whole system can dynamically adjust the amount of koji added according to the feedback data of the belt scale 101 and the running speed of the conveyor belt machine 20 to ensure the accuracy of the koji addition. Further, a plurality of stirrers are arranged in the first-stage cooling bin 31, the second-stage cooling bin 32 and the third-stage cooling bin 33, so that compared with the one-stage airing equipment in the prior art, there are more stirring devices and the distribution is more dense, so that the whole equipment can extend the airing and stir the fermented grains at the same time, so that the cooling process is more uniform, which better solves the problem of significant local temperature difference in the airing process in the prior art. Further, the infrared temperature sensing element 302 can also detect its temperature and implement regulation, so that the airing temperature can be controlled, and the yield and quality of the original wine are guaranteed. Furthermore, the cooling air in the tertiary cooling bin 33 can also be transported to the secondary cooling bin 32 through the ventilation duct 301 for reuse, which not only improves the cooling efficiency but also effectively saves energy.

[0057] In summary, by adjusting the frequency of the conveyor mesh belt machine 20, the power of the blower in the cooling device 30, and the temperature and flow rate of the cooling water in the cold air system 50, the purpose of controlling the drying temperature of the mash can be achieved. In winter when the natural temperature is low, the cold air system 50 can be turned off, and the mash can be cooled to the set temperature by natural wind cooling. It is only necessary to adjust the frequency of the conveyor mesh belt machine 20 and the power of the blower, which can further reduce energy waste. In summer when the natural temperature is high, the blower power can be turned to the maximum, and the frequency of the conveyor mesh belt machine 20 can be adjusted to the minimum, and the cold air system 50 can be turned on, and the temperature and flow rate of the circulating water in the cold air system 50 can be adjusted, so that the final drying temperature of the mash can be controlled, so that it can be cooled to the set temperature quickly to improve the cooling efficiency.
