Description

Technical Field

[0001] The invention relates to the technical field of rice wine brewing, and more specifically, to a method for accelerating rice wine aging by top ventilation, and also to a rice wine ventilation aging system. Background Art

[0002] At present, most rice wine production enterprises in China use pottery jars to store rice wine, which usually needs to be stored for at least one year before it can be sold. Some famous and high-quality rice wines need to be stored for more than three years. Although the aging effect of rice wine stored in pottery jars is better, many shortcomings of pottery jars have always troubled rice wine enterprises: ① The pottery jar container is fragile and easily damaged during transportation and storage; ② The pottery jar is small in size; ③ The jar wall has many pores, and the storage loss is large. The normal loss of one year of storage is more than 2%; ④ The pottery jar has many leaks and defects, and needs to be repaired frequently, which requires a lot of maintenance work; ⑤ The pottery jar cannot be mechanized, and it requires manual sealing, cylinders, and wine pouring, which is cumbersome and inefficient.

[0003] At present, some rice wine production companies have begun to try to use large tanks to store wine instead of pottery jars. However, after a period of wine storage practice, the results are not satisfactory, and the wine often matures slowly. Since large tanks are usually made of materials such as stainless steel, their surfaces do not have the microporous structure of pottery jars. During the aging process, the wine only contacts the air through the upper liquid surface. Moreover, during the storage process, the tank needs to maintain a relatively clean environment and the top is closed. During the storage process, the contact between the unit volume of wine and the air is limited, which greatly limits the aging efficiency of large tank wine.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0015] The present invention is further configured such that the inner cavity of the tank body is provided with a ventilation assembly, and the ventilation assembly is connected to the air inlet pipe through a connecting pipe, and can guide the air.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] This embodiment discloses a method for accelerating the aging of rice wine by top ventilation. The rice wine is stored in a tank body with a large volume, generally 100-500m 3 Large tanks are used to store wine. Compared with ordinary ceramic jars, it can improve the efficiency of space utilization, and the amount of wine in the same tank is larger, making it easier to control the consistency of the wine.

[0031] During the aging process, the yellow wine adopts the yellow wine ventilation aging system for aging, and the aging cycle is 1-2 years. During aging, the new yellow wine pulp is poured into the tank body, and the liquid surface of the yellow wine is at a certain distance from the top of the inner cavity of the tank body, forming a top space with a certain volume. The volume of the inner cavity of the tank body is V1, and the volume of the top space is V2. The volume of the top space is roughly V2 is 1 / 10-1 / 8 of the volume of the inner cavity of the tank body V1.

[0032] Sterile air is introduced into the top space, and the oxygen content of sterile air is 2.0-8.0 mg / L. In addition, the top space is ventilated regularly to keep the air in the top space in a relatively circulated state. The original air can be discharged regularly and fresh air can be introduced into the top space to increase the total amount of air that the volume of wine can contact, thereby increasing the contact ratio of air and rice wine in disguised form, and always maintaining high aging efficiency. In addition, since the oxygen content in sterile air is low, much lower than the oxygen content in normal air, the wine can be stored for a long time without being prone to sourness.

[0033] The temperature of the rice wine in the tank is controlled at 8-15 degrees, and the temperature of the sterile air is also 8-15 degrees. The rice wine can be stored at a suitable storage temperature, which can not only achieve long-term storage and prevent sourness, but also avoid the problem of insufficient chemical reaction activation energy, slow chemical reaction speed, insufficient ester production, and slow wine aroma due to too low temperature, which can promote the aging of rice wine.

[0034] During the ventilation process, sterile air is directly introduced into the top space, rather than below the liquid surface of the rice wine. If the air is introduced below the liquid surface of the rice wine, the air will generate bubbles in the rice wine and generate an upward flow at the bottom of the wine, carrying the fungal components and sediments at the bottom of the rice wine to the upper layer of the liquid surface, or even directly exposing them to the air, destroying the fungal flora inside the rice wine, causing the rice wine to change its taste or even become sour, which is not conducive to long-term wine storage.

[0035] This embodiment adopts the method of directly introducing sterile gas into the top space, which can not only increase the ventilation volume of the rice wine in the tank body, but also will not directly affect the bacterial environment below the rice wine liquid surface, which is conducive to the long-term storage and aging of the rice wine.

[0036] In this embodiment, the frequency of ventilation can be controlled according to the ventilation volume each time. The general ventilation frequency is 1-12 times per month; and the ventilation volume is maintained at 0.12-0.17L 气 / L 酒 If the ventilation volume of a single ventilation is small, you can compensate by appropriately increasing the number of ventilations to maintain a basically consistent ventilation volume each month.

[0037] Specifically, during the aging process of rice wine, 400m 3 The volume of rice wine in the tank is 350-360m3, which is equivalent to about 40-50m3 of head space in the tank. During the aging process, the ventilation volume is controlled at about 48m3 per month. 3 The specific ventilation volume is 0.137L. 气 / L 酒 / moon.

[0038] During the ventilation process, the top space is first evacuated and then inflated. The evacuation and inflation are continuous, which can achieve efficient ventilation of the top space. The following lists five different ventilation conditions for explanation, see Table 1 for details:

[0039] Table 1 Ventilation conditions of five groups of different tubes

[0040] Tank No. Pumping (hours) Air blowing (hours) Frequency (times / month) <![CDATA[Ventilation volume (m 3 / time)]]> 1 2 2 12 4 2 4 4 6 8 3 6 6 4 12 4 8 8 3 16 5 12 12 2 24 6 24 24 1 48

[0041] For ordinary pottery jars, the storage capacity of rice wine in the pottery jar is generally 22-23kg. When rice wine is stored in a pottery jar, the specific surface area of ​​rice wine and the air in the top space is approximately 6.79-10.13cm 2 / kg.

[0042] Using the 400m in this embodiment 3 The storage capacity of rice wine is 350-360m3. The size ratio of the tank is controlled appropriately. For example, if the tank is a cylindrical container with a bottom diameter of 5.5m, the specific surface area of ​​rice wine and the air in the top space is approximately 0.66-0.68cm 2 / kg, which is less than 1 / 10 of that stored in pottery jars. However, by the aging method in this embodiment, ventilation is performed in the top space, which can increase the total amount of air flowing through the top space, and the reacted air can be discharged regularly and fresh sterile air can be injected, thereby enlarging the contact ratio of air and rice wine in disguise, always maintaining high aging efficiency, shortening the rice wine aging cycle, and reducing the time and space costs in the rice wine production process.

[0043] Furthermore, during the rice wine aging process, an electric field can be applied to the rice wine, and the rice wine can be further treated by the electric field, so that the rice wine aging can be achieved more efficiently. The electric field treatment is carried out in the final stage of the rice wine aging, and the electric field is controlled to be 1.0-5.0kv / cm, and the duration is 10-30s. Further treatment of the rice wine by the electric field can improve the taste and quality of the rice wine, improve the aging efficiency of the rice wine, and shorten the production cycle of the rice wine aged for many years.

[0044] Embodiment 2

[0045] This embodiment discloses a method for accelerating the aging of rice wine by top ventilation. Figure 1-Figure 8 A detailed explanation is given and the rice wine ventilation and aging system is further designed.

[0046] The rice wine ventilation and aging system in this embodiment is suitable for the rice wine aging method in the above-mentioned embodiment. Sterile air is introduced into the top space 101 of the upper layer of the rice wine tank body 1, and the air in the top space 101 can be replaced regularly to ensure that the air in the top space 101 is always fresh air, thereby having a relatively high aging efficiency.

[0047] Reference Figure 1 As shown, a large tank body 1 is used as a container for storing rice wine, and the inner cavity of the tank body 1 forms a top space 101 corresponding to the upper part of the liquid level of the rice wine.

[0048] The pipe body is provided with an air inlet pipe 2 and an air outlet pipe 3, both of which are connected to the top space 101, and air can be exchanged into the top space 101 through the air inlet pipe 2 and the air outlet pipe 3. In order to avoid the situation where air backflow occurs, a one-way ventilation valve can be installed at the air inlet pipe 2 and the air outlet pipe 3, so that the air inlet pipe 2 can supply air to the top space 101 in one direction, and the air outlet pipe 3 can discharge air from the top space 101 in one direction, ensuring smooth air circulation. During the ventilation process, the air in the top space 101 can be replaced.

[0049] The other end of the air inlet pipe 2 is connected to an air supply device, which can process the air, sterilize the air, and control the temperature and oxygen content of the air to obtain sterile air that meets the aging requirements.

[0050] Further, refer to Figure 2-Figure 4 As shown, a ventilation assembly is provided in the inner cavity of the tank body 1, and the ventilation assembly is connected to the air inlet pipe 2 through a connecting pipe 4, so as to guide the air. The ventilation assembly specifically includes a top plate 6 and a partition assembly 7, and the top plate 6 is located in the top space 101 and is arranged roughly horizontally. A ventilation hole 601 is opened in the middle of the top plate 6, and the ventilation hole 601 is connected to the connecting pipe 4. The partition assembly 7 is located at the lower side of the top plate 6, and the partition assembly 7 forms an air guide channel.

[0051] The air guide channel is connected to the ventilation hole 601 near the middle of the top plate 6, extends from the middle of the top plate 6 to the peripheral direction, and opens outward at the outermost peripheral position of the partition assembly 7. The upper side of the partition assembly 7 is integrally connected to the top plate 6, and the upper side of the air guide channel is closed by the top plate 6. The lower side of the partition assembly 7 can be immersed in the rice wine, and the lower side of the air guide channel can be closed by the liquid surface of the rice wine. The space between the top plate 6 and the rice wine liquid surface can be separated by the partition assembly 7 to form a tortuous air guide channel.

[0052] When fresh sterile air is passed into the top space 101, it can flow along the tortuous air guide channel. During the circulation process, the originally existing air can be squeezed out, so that the air in the air guide channel can be fully ventilated; and, when the sterile air flows in the air guide channel, it can always be in direct contact with the liquid surface, and has good contact efficiency.

[0053] Specific reference Figure 3 , Figure 4 As shown, the partition assembly 7 includes a plurality of annular partitions 701, each of which has a different ring size and is arranged in a concentric structure from small to large, and each of which is roughly centered on the connection hole. The upper side of the annular partition 701 is integrally connected to the top plate 6, and each of the annular partitions 701 is provided with a notch 702, so that the inner and outer sides of the annular partition 701 can be connected through the notch 702.

[0054] An annular channel is formed between adjacent layers of annular partitions 701 , and each layer of annular channels can be interconnected through the notch 702 , so that a sequentially connected air guide channel can be formed between the inner and outer layers of annular partitions 701 .

[0055] Furthermore, the gaps 702 between two adjacent layers of annular partitions 701 are located on both sides of the back, so that a tortuous passage can be formed between the two layers of annular partitions 701, thereby extending the length of the path for air flow and also extending the time that the air is in contact with the wine during the process of flowing in, thereby improving the aging efficiency to a certain extent.

[0056] Further, refer to Figure 5 As shown, the air guide component 5 adopts a structure that moves up and down, and a telescopic rod 501 is provided on the upper part of the top plate 6, and the telescopic end of the telescopic rod 501 extends downward and is fixedly connected to the top plate 6. The up and down movement of the air guide component 5 can be controlled by the telescopic rod 501. When the telescopic rod 501 is extended downward, the lower part of the air guide component 5 can be immersed in the wine; when the telescopic rod 501 is retracted up and down, the air guide component 5 can completely leave the wine, forming two different states. In addition, in order to ensure the smooth movement of the air guide component 5, the connecting pipe 4 can adopt a flexible hose, so as not to cause interference and keep the air intake unobstructed.

[0057] Further, refer to Figure 6 As shown, the ventilation assembly also includes a bottom plate 8, which is located at the lower side of the partition assembly 7, and the bottom plate 8 is fixedly connected to each annular partition 701. The entire ventilation assembly forms a three-layer structure, the upper layer is the top plate 6, the lower layer is the bottom plate 8, and the middle layer is the partition assembly 7 composed of annular partitions 701, and a tortuous air guide channel is formed between the top plate 6 and the bottom plate 8.

[0058] When the ventilation assembly descends and the bottom plate 8 and part of the partition assembly 7 enter the wine, the wine will flow along the air guide channel into the upper side of the bottom plate 8. At this time, the liquid level will compress the space of the air guide channel, and the actual height of the air guide channel will be small. The wine can also come into contact with the air in the air guide channel. Sterile air can always be in contact with the wine throughout the entire flow path of the air guide channel, thereby ensuring the aging efficiency.

[0059] In order to ensure that the wine can enter the upper layer of the bottom plate 8 more smoothly, a plurality of through holes 801 are provided on the bottom plate 8, so that the wine can enter the air guide channel on the upper layer of the bottom plate 8 through the through holes 801. Each through hole 801 is provided along the path of the air guide channel, and a plurality of through holes 801 are provided between adjacent annular partitions 701, so that the wine can enter various positions on the upper side of the bottom plate 8 smoothly.

[0060] The bottom plate 8 is a cone-shaped structure, and the height of the upper surface of the bottom plate 8 gradually decreases from the middle to the sides. In addition, corresponding through holes 801 are provided between adjacent layers of annular baffles 701, and the through holes 801 are located near the inner layer of annular baffles 701. Figure 6 shown.

[0061] When the air guide assembly 5 is lowered, the bottom plate 8 and part of the partition assembly 7 at the bottom of the air guide assembly 5 will be immersed in the wine, and the wine will flow into the upper side of the bottom plate 8 from the through hole 801 of the bottom plate 8. At this time, the air inlet pipe 2 will introduce fresh sterile air into the air guide assembly 5, and the fresh air can flow along the air guide channel, squeezing out most of the air originally retained in the air guide channel, and the squeezed air will be discharged from the air outlet pipe 3, so that the ventilation action can be smoothly realized, and the fresh sterile air can fully contact with the air when flowing through the air guide channel, so that a better aging effect can be achieved during the ventilation process.

[0062] When the air guide assembly 5 rises, the bottom plate 8 and part of the partition assembly 7 at the bottom of the air guide assembly 5 will leave the wine, and part of the wine in the air guide channel will flow directly down from the through hole 801; in the process of falling, the contact between the wine and the air can be increased, and the aging efficiency of the wine can be further improved; because the position of the through hole 801 between the two layers of annular partitions 701 is relatively close to the inner annular partition 701, a storage space 802 can be formed between the outer annular partition 701 and the bottom plate 8, and a certain amount of wine can be stored in the storage space 802. In addition, because the upper side of the bottom plate 8 forms a conical structure, the wine in the storage space 802 can flow along the inclination direction of the bottom plate 8 to the outer periphery of the bottom plate 8, and flow out from the notch 702 of the annular partition 701, gradually flow toward the outer periphery of the air guide assembly 5, and finally flow out from the notch 702 of the outermost annular partition 701, and reunite with other wine. During the circulation of the wine in the storage space 802, this part of the wine can fully contact with the air, thereby having a higher aging efficiency in this process. Moreover, during the process of the wine entering and exiting the air guide channel, it can drive the air in the air guide channel to move forward, thereby maintaining a better consistency between the air in the air guide channel and the air in the top space 101, which is beneficial to the uniformity of the aging process.

[0063] During the wine aging process, the lifting and lowering of the air guide assembly 5 can carry part of the wine upward, and the automatic circulation of the wine can increase the direct contact efficiency between the wine and the air, thereby improving the overall aging efficiency of the wine. In addition, during the lifting and falling of the wine, the flow of the wine in the tank body 1 can be promoted, making the wine more uniform.

[0064] Further, refer to Figure 7 , Figure 8 As shown, an openable and closable sealing plug 902 is also provided at the through hole 801. When the bottom plate 8 enters into the wine, the sealing plug 902 can open the through hole 801, so that the wine can smoothly enter the air guide channel from the through hole 801; when the bottom plate 8 leaves the wine, the sealing plug 902 can close the through hole 801 to prevent the wine in the air guide channel from directly flowing out of the through hole 801, so that the wine can gradually flow outward along the air guide channel, which can improve the efficiency of the wine contacting with the air during the circulation process, thereby improving the aging efficiency of the wine.

[0065] Specifically, a connecting rod 901 is inserted into the through hole 801, and the connecting rod 901 passes through the through hole 801 from top to bottom. The diameter of the connecting rod 901 is smaller than that of the through hole 801, and the wine can flow smoothly through the gap between the connecting rod 901 and the through hole 801. A sealing plug 902 is provided at the upper end of the connecting rod 901, and the lower half of the sealing plug 902 is an inverted cone structure. The cone portion of the sealing plug 902 can be embedded in the through hole 801, thereby closing the through hole 801.

[0066] The lifting and lowering action of the sealing plug 902 can be achieved by the combined effect of buoyancy and gravity. The bottom plate 8 is immersed in the wine, the connecting rod 901 and the sealing plug 902 float up, and the sealing plug 902 opens the through hole 801. The bottom plate 8 moves upward to leave the wine, and the connecting rod 901 and the sealing plug 902 fall down again under the action of gravity, and the sealing plug 902 can close the corresponding through hole 801.

[0067] Furthermore, a limit plate 9 is provided at the lower part of the bottom plate 8, and the lower end of each connecting rod 901 is fixedly connected to the bottom plate 8, so that the limit plate 9 and each connecting rod 901 and the sealing plug 902 can realize synchronous lifting and lowering. The limit plate 9 is made of a buoyant material, and the limit plate 9 can float, providing additional buoyancy and counterweight for the lifting and lowering action of the sealing plug 902.

[0068] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
