Description

Technical Field

[0001] This application relates to the technical field of buckwheat rice wine aging equipment, and in particular to a buckwheat rice wine aging processing equipment and processing technology. Background Technology

[0002] During the production of alcoholic beverages, the beverages are stored for a period of time depending on their type in order to achieve the desired quality.

[0003] The aging of alcoholic beverages typically relies on time, but this process requires significant storage space, increasing facility costs. Therefore, to accelerate the aging process, physical or chemical methods are used to process the alcoholic beverages.

[0004] Currently, ozone and hydroxyl radicals are typically introduced into the alcoholic beverages. The strong oxidizing properties of hydroxyl radicals and ozone are used to oxidize the unsaturated compounds in the alcoholic beverages into water and carbon dioxide. At the same time, the heavy metal components in the alcoholic beverages are reduced and precipitated, thereby accelerating the aging process of the alcoholic beverages.

[0005] However, in the process of introducing ozone, the ozone is simply introduced directly from above the alcoholic beverage, causing the ozone to come into direct contact with the surface alcoholic solution, thereby affecting the oxidation rate of unsaturated compounds in the alcoholic beverage by the ozone.

[0006] Therefore, a new technical solution is needed to address the above problems. Summary of the Invention

[0007] In order to make ozone more easily soluble in the wine and accelerate the oxidation rate of unsaturated compounds, this application provides a buckwheat rice wine post-fermentation processing equipment and processing technology.

[0008] This application provides a buckwheat rice wine post-fermentation processing equipment and process, which adopts the following technical solution: A post-fermentation processing device for buckwheat rice wine includes a hydroxyl conversion tower, a metal ion catalytic tower, a complexation reaction tower, a photoelectron purification device, and a purification tower connected in sequence for conveying the wine. The hydroxyl conversion tower includes a tower body, an ultraviolet light generator disposed within the tower body, an air inlet pipe for injecting ozone into the tower body, and several grid plates disposed within the inner cavity of the tower body. The air inlet pipe is coaxially disposed within the inner cavity of the tower body, and its upper end is rotatably connected to the upper end of the tower body. The upper end of the air inlet pipe is used to connect to the ozone generator. Several horizontally arranged exhaust pipes are circumferentially disposed at the lower end of the air inlet pipe. The axis of the exhaust outlet of the exhaust pipe is set at an angle to the axis of the exhaust pipe connected to it. The grid plates are circumferentially disposed around the axis of the air inlet pipe, and the exhaust outlets of the exhaust pipes face the grid plates.

[0009] By adopting the above technical solution, after ozone is introduced into the bottom of the wine, the large bubbles are turned into small bubbles by using a grid plate. Then, the gas outlet is rotated to allow the small bubbles to diffuse in the wine. By reducing the volume of the bubbles, the contact area between the bubbles and the wine is increased when the same amount of gas is introduced, making it easier for the ozone to dissolve into the wine.

[0010] Optionally: The tower body is provided with a guide plate coaxially arranged with the air inlet pipe. The grid plate is arranged on the end face of the guide plate near the exhaust pipe. A gap is left between the grid plate and the guide plate for the passage of air bubbles. The liquid moves along the side wall of the guide plate near the air inlet pipe toward the axis of the air inlet pipe.

[0011] By adopting the above technical solution, when ozone is sprayed out from the outlet and drives the wine to flow to the guide plate, the guide plate guides the wine and drives the wine to move towards the air inlet, making it easier for the bubbles formed by ozone to mix in the wine.

[0012] Optionally: The tower body is provided with a moving mechanism that drives the guide plate and the air inlet pipe to move vertically. The moving mechanism includes a sliding frame, a plurality of guide rods disposed on the sliding frame, and a driving component that drives the guide rods to move vertically. The sliding frame is arranged around the guide plate, the guide plate is disposed on the sliding frame, the guide rods pass through the upper end of the tower body and slide in cooperation with the tower body, and the upper end of the air inlet pipe is connected to the guide rods.

[0013] By adopting the above technical solution, when ozone is injected into the wine at the gas outlet, the injection position of the ozone can move up and down repeatedly, so that the bubbles formed by the ozone are more easily distributed in various positions in the wine, thus accelerating the efficiency of ozone dissolving in the wine.

[0014] Optionally: The guide plate includes several support plates arranged circumferentially around the axis of the intake pipe. The middle part of the support plate away from the side wall of the intake pipe is rotatably connected to the sliding frame. The upper end of the support plate rotates to cover the upper end of the exhaust pipe outlet, and the lower end of the support plate rotates to cover the lower end of the exhaust pipe outlet.

[0015] By adopting the above technical solution, when moving upward, the support plate rotates to cover the lower end of the air outlet, and when moving downward, the support plate rotates to cover the upper end of the air outlet. This allows the support plate to drive the water flow towards the air inlet pipe during vertical movement, accelerating the mixing of ozone into the wine.

[0016] Optionally: The top and bottom walls of the tower body are coaxially provided with drive rings that drive the support plate to rotate. The drive rings are provided with guide arc surfaces on their side walls near their axes, and the ends of the support plates move along the guide arc surfaces.

[0017] By adopting the above technical solution, when the support plate moves to the upper and lower ends close to the tower body, the guide arc surface applies force to the support plate, thereby causing the support plate to rotate automatically, making the use of the support plate more convenient.

[0018] Optionally: Each of the support plates has a fitting inclined surface on its side wall near the adjacent support plate. The fitting inclined surfaces are respectively located on the upper and lower sides of the rotation axis of the support plate. The ends of the fitting inclined surfaces on the same side of the rotation axis of the support plate that are away from the rotation axis are close to each other, and the fitting inclined surfaces of adjacent support plates abut against each other.

[0019] By adopting the above technical solution, when the support plate is rotated to a certain angle, the adjacent support plates abut against each other, thereby forming a complete structure, which makes it easier for the wine to move towards the direction of the air inlet pipe.

[0020] Optionally: The upper and lower sides of the sliding frame are vertically sliding limit rings, the limit rings are connected by limit rods and move synchronously, the inner wall of the limit ring abuts against the side wall of the guide plate that flips towards the air outlet away from the exhaust pipe, and the drive ring abuts against the side wall of the limit ring away from the mounting ring to drive the mounting ring to move.

[0021] By adopting the above technical solution, when the guide plate moves, the limiting ring abuts against the side of the guide plate opposite to its moving direction, thereby enabling the support plate to maintain a stable position.

[0022] Optionally: The air inlet pipe is provided with a connection mechanism for connecting to the ozone generator. The connection mechanism includes a connector on the air inlet pipe, a rotary joint on the ozone generator, and a hose for connecting the rotary joint to the connector. Several guide rods are coaxially fixed on the connector, and the guide rods pass through the rotary joint and slide in cooperation with the rotary joint.

[0023] By adopting the above technical solution, the air intake pipe can always maintain a connection with the ozone generator during vertical movement and rotation, so that ozone can be continuously introduced into the wine.

[0024] Optional: The tower body is further provided with an auxiliary stirring mechanism, which includes a drive sleeve coaxially fixed to the outside of the air inlet pipe, several stirring blades coaxially sleeved on the outside of the drive sleeve, and a guide member rotatably connected to the stirring blades. The horizontal cross-section of the drive sleeve is polygonal. The drive sleeve passes through the stirring blades and slides with the stirring blades. The drive sleeve rotates synchronously with the stirring blades. The upper end of the guide member is rotatably connected to the stirring blades. Several guide grooves with different bottom heights are opened on the inner wall of the tower body. The end of the guide member away from the stirring blades is set in the guide groove and slides vertically. The bottom height of the guide groove set in the lower guide member is lower. The upper end of the exhaust pipe is used to abut against the guide member and drive the guide member to move upward.

[0025] By adopting the above technical solution, as the guide plate moves downward, the stirring blades can continue to stir the wine above, so that the newly flowing wine can mix with the wine mixed with ozone more quickly, thereby accelerating the mixing efficiency with ozone.

[0026] A post-fermentation process for buckwheat rice wine includes the following steps: S1. Introduce ozone into the wine and irradiate the ozone-introduced wine with ultraviolet light. Then stop introducing ozone and continue irradiating with ultraviolet light until all the ozone is decomposed. S2. Metal ions are introduced into the wine and a complexation reaction is carried out using a high-energy plasma generator. S3. Filter the complexed wine.

[0027] By adopting the above technical solution, ozone is used to remove unsaturated compounds in the wine through oxidation, and then metal ions are introduced to meet the content of metal ions that permeate into the wine during earthenware jar storage, thereby achieving the purpose of rapid aging.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. Introduce ozone into the wine and use a grid plate to break up large bubbles into smaller bubbles, increasing the contact area between ozone and the wine, making it easier for ozone to dissolve into the wine. 2. The outlet moves vertically back and forth, thereby moving the ozone injection position vertically. The guide plate also moves the liquid towards the air inlet, making it easier for the ozone bubbles in the liquid to fill the liquid, further increasing the mixing efficiency of ozone and liquid.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a post-fermentation processing device for buckwheat rice wine, such as... Figure 1 As shown, the system includes a hydroxyl conversion tower 1, a metal ion catalytic tower 2, a complexation reaction tower 3, a photoelectronic purification device 4, and a purification tower 5, which are connected in sequence and used to transport the wine. The wine is passed into the hydroxyl conversion tower 1 for oxidation to remove heavy metal ions and aldehydes. Then, metal ions are injected into the metal ion catalytic tower 2 and undergo a complexation reaction with the complexation reaction tower 3 to form macromolecular patterns. After that, residual ozone and balance potential energy are removed in the photoelectronic purification device 4. Finally, the purification tower 5 is used to filter impurities in the wine to complete the aging process.

[0033] like Figure 2 As shown, the hydroxyl conversion tower 1 includes a tower body 11, an ultraviolet light generator 12 disposed within the tower body 11, an inlet pipe 13 for injecting ozone into the tower body 11, and several grid plates 14 disposed within the inner cavity of the tower body 11. An inlet pipe communicating with the inner cavity is disposed at the upper end of the side wall of the tower body 11, through which alcohol is injected into the tower body 11. An outlet pipe is disposed at the lower end of the tower body 11, through which the alcohol is output to the metal ion catalytic tower 2. The inlet pipe 13 passes through the upper end face of the tower body 11 and extends into the inner cavity of the tower body 11, and the inlet pipe 13 is coaxially rotatably coupled with the tower body 11. The lower end of the air intake pipe 13 is provided with several horizontally arranged exhaust pipes 15. All exhaust pipes 15 are connected to the inner cavity of the air intake pipe 13, and the exhaust pipes 15 are inclined away from the air outlet of the air intake pipe 13. The axis of the air outlet is set at an angle with the axis of the exhaust pipe 15 connected to it. The upper end of the air intake pipe 13 is used to connect to an ozone generator, so that ozone is injected into the wine through the air outlet. In the process of filling the wine with ozone, the inlet pipe can rotate to make the ozone distribution in the wine more uniform.

[0034] like Figure 3As shown, the tower body 11 is also equipped with a guide plate 16 that drives the ozone-containing bubbles to move toward the center of the wine. The guide plate 16 is coaxially arranged with the air inlet pipe 13. The side wall of the guide plate 16 near the air outlet is arc-shaped. So when ozone is sprayed toward the side wall of the guide plate 16, the water flow can flow toward the air inlet pipe 13 under the guidance of the guide plate 16. This causes the wine containing ozone bubbles to move toward the wine at the air inlet pipe 13, making it easier for the ozone to mix in the wine.

[0035] like Figure 2 and Figure 4 As shown, because the air outlet is located below the inner cavity of the tower body 11, the ozone-containing bubbles need to rise slowly, resulting in a relatively low mixing efficiency between the ozone and the liquid. Therefore, a moving mechanism 6 is provided inside the tower body 11 to drive the guide plate 16 and the air inlet pipe 13 to move vertically. The moving mechanism 6 includes a sliding frame 61 installed inside the tower body 11, several guide rods 62 installed on the sliding frame 61, and a driving component 63 that drives the guide rods 62 to move vertically. The axis of the sliding frame 61 is aligned with the axis of the air inlet pipe 13. The sliding frame 61 is arranged around the outside of the guide plate 16, and the guide plate 16 is connected to the sliding frame 61. The guide rods 62 are circumferentially arranged on the upper end face of the sliding frame 61, and the upper end of the guide rods 62 passes through the upper end face of the tower body 11 and slides with the tower body 11. A mounting ring 64 is fixed to the upper end of the guide rods 62. A plurality of horizontally arranged connecting rods 65 are axially fixed to the inner wall of the mounting ring 64. A connecting ring 66 is fixed to the end of each connecting rod 65 away from the mounting ring 64. The connecting ring 66 is sleeved on the outside of the air inlet pipe 13 and rotatably connected to the air inlet pipe 13, thereby driving the air inlet pipe 13 and the guide plate 16 to move synchronously. In this embodiment, the driving component 63 is a combination of a lead screw and a motor. The lead screw is rotatably connected to the tower body 11 and passes through the mounting ring 64, threadedly engaging with the mounting ring, thereby driving the mounting ring 64 to move.

[0036] like Figure 3 As shown, during the vertical movement of the guide plate 16, when moving in one direction, it becomes difficult to push the liquid towards the axis of the tower body 11. Therefore, the guide plate 16 includes several support plates 161 arranged circumferentially around the axis of the air inlet pipe 13. Each support plate 161 is rotatably connected to the side wall of the sliding frame 61 near the axis of the air inlet pipe 13. The rotation axis of the support plate 161 is on the same horizontal plane as the axis of the air outlet. The upper end of the support plate 161 can rotate to cover the upper end of the air outlet, and the lower end of the support plate 161 can rotate to cover the lower end of the air outlet. Thus, during the vertical movement of the guide plate 16, the liquid mixed with ozone can be pushed towards the axis of the air inlet pipe 13.

[0037] The grid plates 14 are respectively set on the end face of the support plate 161 near the air inlet pipe 13, and there is a gap between the grid plates 14 and the support plate 161. When ozone is sprayed into the wine at the air outlet, the wine mixed with ozone will pass through the grid plates 14 and the large bubbles will be broken into small bubbles by the pores on the grid plates 14. Then, the guide plate 16 will push the small bubbles toward the air inlet pipe 13, thereby accelerating the mixing efficiency of ozone and wine.

[0038] Each support plate 161 has a contacting inclined surface 162 on its side wall near the adjacent support plate 161. The contacting inclined surfaces 162 are respectively located on both sides of the rotation axis of the support plate 161, with the ends of the contacting inclined surfaces 162 on the same side of the rotation axis of the support plate 161 that are away from the rotation axis approaching each other. Thus, when the support plate 161 rotates upward and downward, the adjacent support plates 161 can still be in contact to form a complete guide plate 16, allowing the wine mixed with ozone bubbles to flow towards the middle of the tower body 11.

[0039] like Figure 2 As shown, the upper and lower ends of the inner cavity of the tower body 11 are coaxially provided with drive rings 17 that drive the support plate 161 to rotate. The axis of the drive ring 17 coincides with the axis of the air inlet pipe 13. The inner wall of the drive ring 17 is provided with guide arc surfaces 171 that drive the support plate 161 to move. The curvature of the guide arc surface 171 is the same as the curvature of the guide plate 16. Thus, when the support plate 161 contacts the guide arc surface 171 and rotates along the guide arc surface 171, the support plate 161 can rotate to the same state as the guide arc surface 171, so that the adjacent support plates 161 fit together and can drive the water flow.

[0040] like Figure 3 As shown, during the vertical movement of the guide plate 16, the liquid exerts a force on the guide plate 16 that hinders its movement, causing the guide plate 16 to rotate in the opposite direction of movement, thus affecting the flow of ozone bubbles toward the air intake pipe 13. Therefore, both the upper and lower sides of the sliding frame 61 have vertically sliding limit rings 67, which are connected by limit rods 68 to allow the two limit rings 67 to slide synchronously. The limit rods 68 pass through the mounting ring 64 and are slidably connected to the mounting ring 64. The inner wall of the limit ring 67 abuts against the side wall of the support plate 161 away from the air intake pipe 13 after it has been flipped, thereby restricting the support plate 161 from moving in the opposite direction of movement of the sliding frame 61. The drive ring 17 can abut against the limit ring 67 to drive the limit ring 67 to move, thereby locking and unlocking the support plate 161.

[0041] like Figure 4As shown, the air intake pipe 13 is also equipped with a connection mechanism 7 for connecting to the ozone generator. The connection mechanism 7 includes a connector 71 coaxially disposed at the upper end of the air intake pipe 13, a rotary connector 72 disposed on the ozone generator, and a flexible hose 73 connecting the rotary connector 72 to the connector 71. The rotary connector 72 is coaxially disposed with the connector 71. Several vertically disposed guide rods 78 are coaxially fixed on the connector 71. The upper ends of the guide rods 78 pass through the rotary connector 72 and slide in cooperation with the rotary connector 72, so that the rotary connector 72 can rotate synchronously with the connector 71, and the rotary connector 72 can still rotate synchronously during the vertical movement of the connector 71.

[0042] like Figure 2 As shown, after the guide plate 16 moves downward, unmixed ozone-laden liquor still flows into the tower body 11. Therefore, an auxiliary stirring mechanism 8 for stirring the liquor is also provided inside the tower body 11. The auxiliary stirring mechanism 8 includes a drive sleeve 81 coaxially fixed to the outside of the air inlet pipe 13, several stirring blades 82 coaxially sleeved on the drive sleeve 81, and a guide member 83 rotatably connected to the stirring blades 82. The horizontal cross-section of the drive sleeve 81 is a regular hexagon. The stirring blades 82 slide along the drive sleeve 81, and the drive sleeve 81 drives the stirring blades 82 to rotate synchronously. A rotating ring 84 is rotatably connected to the lower end of the stirring blades 82. A gap is left between the rotating ring 84 and the drive sleeve 81, and the guide member 83 is fixed to the side wall of the rotating ring 84. The inner wall of the tower body 11 is provided with several vertically arranged guide grooves 18. The bottom surfaces of the guide grooves 18 are at different heights, and the guide grooves 18 pass through the drive ring 17. The end of the drive member 63 away from the rotating ring 84 slides within the guide groove 18. The bottom surface of the guide groove 18 through which the guide member 83 connected to the lower stirring blade 82 slides is at a lower height. The upper end of the exhaust pipe 15 can abut against the rotating ring 84, thereby sequentially driving the stirring blade 82 to move upward, making the vertical movement of the exhaust pipe 15 less affected.

[0043] The implementation principle of this embodiment is as follows: The ozone generator injects ozone into the liquid through the air inlet pipe 13. When the ozone is sprayed out from the air outlet, it drives the air inlet pipe 13 to rotate. When the bubbles formed by the ozone in the liquid pass through the grid plate 14, the grid plate 14 breaks up the large bubbles into small bubbles. The small bubbles move towards the air inlet pipe 13 under the drive of the guide plate 16. The driving component 63 drives the sliding frame 61 to move vertically. When the support plate 161 contacts the guide arc surface 171, it can rotate along the guide arc surface 171. When the guide arc surface 171 contacts the support plate 161, the driving ring 17 also contacts the limiting ring 67. Thus, when the limiting ring 67 moves, the support plate 161 can rotate. During the vertical movement, the ozone bubbles always move towards the air inlet pipe 13 under the drive of the guide plate 16.

[0044] A post-fermentation process for buckwheat rice wine includes the following steps: S1. Introduce ozone into the wine and irradiate the ozone-introduced wine with ultraviolet light. Then stop introducing ozone and continue irradiating with ultraviolet light until all the ozone is decomposed. S2. Metal ions are introduced into the wine and a complexation reaction is carried out using a high-energy plasma generator. S3. Filter the complexed wine.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
