Description

Technical Field

[0001] The present invention relates to the field of liquor fermentation, and more particularly to a fermentation device for liquor brewing. Background Art

[0002] In the process of brewing liquor, fermentation is one of the key steps. Traditional fermentation methods are usually carried out in sealed fermentation tanks to ensure that the microorganisms in the fermentation process can grow and reproduce in a suitable environment and produce the required alcohol and flavor substances. However, during the fermentation process, yeast and other microorganisms metabolize sugars to produce alcohol and carbon dioxide, which releases a large amount of heat, causing the temperature in the fermentation tank to gradually increase. Excessive temperature not only affects the activity of microorganisms, but also leads to an imbalance in the proportion of fermentation products, affecting the quality and flavor of the final liquor.

[0003] In order to control the temperature inside the fermentation tank, the traditional method is usually to manually open the fermentation tank lid and stir the fermentation raw materials to promote heat dissipation. Although this method is simple and direct, each time the fermentation tank is opened, outside air will enter the tank, which will not only bring in miscellaneous bacteria and destroy the sterile state of the fermentation environment, but also lead to the loss of volatile components (such as alcohol), thereby affecting the quality of the wine. At the same time, it is difficult to achieve precise temperature control by relying on manual stirring, and local overheating or insufficient cooling is prone to occur, which in turn affects the consistency and stability of the fermentation effect. Summary of the Invention

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a fermentation equipment for liquor brewing, which can automatically achieve efficient cooling without opening the fermentation tank, while maintaining a good fermentation environment, reducing the need for manual intervention, and effectively preventing external pollution, thereby ensuring the stability of the fermentation process and the high quality of the product.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 , a fermentation device for brewing liquor, comprising a fermentation tank 1, wherein a rotating tube 2 is rotatably installed in the inner cavity of the fermentation tank 1;

[0030] Also includes:

[0031] The cooling component includes a fixed tube 7 fixedly installed on one side of the top of the fermentation tank 1, and a fan 8 is fixedly installed in the inner cavity of the fixed tube 7. A cavity 5 is opened in the top of the fermentation tank 1, and the fixed tube 7 is connected to the inner cavity of the cavity 5. Through holes 6 are evenly opened on the tube wall of the rotating tube 2. Each group of through holes 6 is located in the cavity 5 and is connected to the inner cavity of the cavity 5. A threaded hole 18 is opened in the side wall of the fermentation tank 1, and a connecting hole 19 is opened in the bottom of the fermentation tank 1. The two ends of the connecting hole 19 are respectively connected to the bottom end of the rotating tube 2 and the threaded hole 18, and the top of the threaded hole 18 is connected to the outside world. A trigger component is provided on one side of the fixed tube 7.

[0032] The trigger assembly is fixedly mounted on a mounting tube 9 on one side of the top of the fermentation tank 1. The mounting tube 9 is connected to the inner cavity of the fermentation tank 1. A transverse tube 10 is fixedly mounted on the inner cavity of the mounting tube 9. An elastic rubber 11 is installed between the inner cavity of the transverse tube 10 and the inner cavity wall of the mounting tube 9. A circular plate 13 is fixedly mounted on one end of the elastic rubber 11. The circular plate 13 is slidably mounted on the inner cavity of the transverse tube 10. Contact blocks 14 are fixedly mounted on the side of the circular plate 13 away from the elastic rubber 11 and the inner cavity of the transverse tube 10. The two groups of contact blocks 14 are non-contact arranged.

[0033] Heat-conducting rods 12 are evenly fixedly installed in the elastic rubber 11. The other end of each group of heat-conducting rods 12 passes through the horizontal tube 10 and extends to the inner cavity of the fermentation tank 1. Stirring rods 3 are evenly fixedly installed on the rod wall of the rotating tube 2. A motor 4 is fixedly installed on the top of the fermentation tank 1. The output shaft of the motor 4 is fixedly installed on the top of the rotating tube 2. The two groups of contact blocks 14 are respectively connected in series with the fan 8 and the motor 4. A feed pipe 25 is fixedly installed on one side of the top of the fermentation tank 1.

[0034] First, the raw materials used for liquor fermentation are boiled and cooled, and then koji is added. Then the feed pipe 25 is opened and poured into the fermentation tank 1 through the feed pipe 25 for fermentation. During the fermentation process, a large amount of heat is released in the process of yeast and other microorganisms metabolizing sugar to produce alcohol and carbon dioxide. The heat will flow upward in the inner cavity of the fermentation tank 1. When this heat flows to the top wall of the inner cavity of the fermentation tank 1 and contacts each group of heat-conducting rods 12, the heat will be transferred to the elastic rubber 11 through the heat-conducting rods 12. At this time, the elastic rubber 11 will gradually expand due to the increase in temperature. The expansion of the elastic rubber 11 will push the circular plate 13 to slide to the right in the inner cavity of the horizontal tube 10. When the circular plate 13 moves, it will drive the contact block 14 on it to move synchronously. When the contact block 14 on the circular plate 13 contacts the contact block 14 on the inner cavity of the horizontal tube 10, the fan 8 and the motor 4 will be controlled to turn on. , when the fan 8 is turned on, it will absorb the external air through the fixed tube 7 and discharge it into the cavity 5. The gas in the cavity 5 will be discharged into the rotating tube 2 through the through hole 6. The gas in the rotating tube 2 will be discharged into the threaded hole 18 through the connecting hole 19. The gas flows upward in the threaded hole 18 and will eventually be discharged to the outside. At this time, the flow of gas in the rotating tube 2 and the fermentation tank 1 can realize the cooling of the fermentation tank 1. The setting of the elastic rubber 11 plays the role of real-time monitoring of the temperature in the fermentation tank 1. When the temperature rises, the fermentation tank 1 can be automatically cooled. Moreover, there is no need to open the fermentation tank 1 frequently, which greatly reduces the chance that the external air may carry miscellaneous bacteria into the fermentation tank 1 and reduces the risk of contamination. At the same time, the closed cooling mechanism avoids the loss of alcohol and other volatile aroma components caused by opening the fermentation tank 1, which helps to maintain the unique flavor of the liquor.

[0035] When the motor 4 is turned on, its output shaft will drive the rotating tube 2 to rotate. When the rotating tube 2 rotates, it will drive the various groups of stirring rods 3 on it to rotate synchronously, so as to achieve stirring of the fermented raw materials in the fermentation tank 1. The internal materials can be fully mixed by stirring, which helps to dissipate heat faster and more evenly in the inner cavity of the fermentation tank 1, avoiding local overheating or insufficient cooling. At the same time, stirring can make the fermented materials more evenly distributed in the entire fermentation tank 1, and increase the contact area between the material and the inner cavity wall of the fermentation tank 1. In this way, the heat generated by the fermentation can be more effectively brought from the inside of the material to the surface, and heat exchange can be achieved by contact with the inner cavity wall of the fermentation tank 1 after cooling, thereby accelerating the overall cooling process. Through automated control, the dependence on manual operation is reduced, which not only reduces labor costs but also improves work efficiency.

[0036] like Figure 2 、 Figure 4 and Figure 5 As shown, a reciprocating threaded tube 15 is provided on the outside of the rotating tube 2, and the reciprocating threaded tube 15 is fixedly installed on the top wall of the inner cavity of the fermentation tank 1. A sleeve 16 is threadedly installed on the outer wall of the reciprocating threaded tube 15, and the sleeve 16 is slidably installed with the rotating tube 2.

[0037] A connecting plate 17 is evenly fixedly mounted on the outer wall of the sleeve 16 , and the connecting plate 17 is located on the lower side of the heat conducting rod 12 .

[0038] When the output shaft of the motor 4 drives the rotating tube 2 to rotate, it will drive the sleeve 16 to rotate synchronously. When the sleeve 16 rotates, it will drive the groups of connecting plates 17 thereon to rotate synchronously. When the sleeve 16 rotates, it will rotate on the outer wall of the reciprocating threaded tube 15. By setting the reciprocating threaded tube 15, a reciprocating thread is set on its outer wall, which can realize the sleeve 16 to move up and down reciprocatingly during the rotation of the outer wall of the reciprocating threaded tube 15. At this time, it can be realized that the groups of connecting plates 17 can move up and down reciprocatingly during the rotation of the reciprocating threaded tube 15. At this time, the connecting plates 17 rotate and move up and down, which can promote the flow of gas on the upper side of the inner cavity of the fermenter 1, thereby improving the uniformity of temperature, avoiding the situation where the temperature in some areas is inconsistent and affects the heat conduction of the heat conducting rod 12, and the fan 8 cannot be stably controlled to start to cool the fermenter 1, thereby effectively ensuring the uniformity of temperature, thereby effectively improving the effect of stable cooling.

[0039] like Figure 2 and Figure 4 As shown, a movable plate 20 is slidably installed in the inner cavity of the mounting tube 9, and the movable plate 20 is located on the upper side of the transverse tube 10. A top plate 21 is provided on the upper side of the movable plate 20, and the top plate 21 is fixedly installed in the inner cavity of the mounting tube 9. A reset spring 22 is fixedly installed between the movable plate 20 and the top plate 21.

[0040] Pressure relief holes 23 are evenly formed in the side wall of the mounting tube 9 , and the top and bottom ends of the pressure relief holes 23 are both connected to the inner cavity of the mounting tube 9 .

[0041] The top end of the pressure relief hole 23 is higher than the top wall of the top plate 21 , and the bottom end of the pressure relief hole 23 is higher than the bottom wall of the movable plate 20 .

[0042] During the fermentation process, microorganisms decompose sugar into alcohol and carbon dioxide. As the fermentation proceeds, a large amount of carbon dioxide gas is released. Since the fermentation tank 1 is sealed for fermentation, the pressure in the fermentation tank 1 will increase. The increased pressure will push the movable plate 20 to move upward in the inner cavity of the mounting tube 9. While the movable plate 20 moves upward, it will squeeze the return spring 22. When the bottom surface of the movable plate 20 moves to the upper side of the bottom end of the pressure relief hole 23, the bottom end of the pressure relief hole 23 is connected to the inner cavity of the mounting tube 9. The gas in the fermentation tank 1 will be discharged through the pressure relief hole 23, which plays the role of automatic pressure relief and can release excess pressure before the pressure reaches a dangerous level. force, thereby preventing the fermentation tank from being deformed, ruptured or otherwise physically damaged due to excessive internal pressure, protecting the safety of the equipment. Appropriate pressure relief helps to maintain the pressure in the fermentation tank 1 within an ideal range, which is particularly important for certain types of fermentation. Avoiding excessive pressure will affect the growth and metabolic activities of microorganisms and the quality of the fermentation products. After the gas is gradually discharged, the pressure in the fermentation tank 1 will gradually return to a normal range. At this time, under the action of the return spring 22, the return spring 22 returns to its initial state and pushes the movable plate 20 downward to its initial position, so that the movable plate 20 can seal the bottom end of the pressure relief hole 23.

[0043] like Figure 1 and Figure 2 As shown, a filter screen 24 is provided on the upper side of the fan 8 , and the filter screen 24 is fixedly installed in the top end of the fixed pipe 7 .

[0044] A discharge pipe 26 is fixedly installed on one side of the bottom of the fermentation tank 1 , and valves are installed in the discharge pipe 26 and the feed pipe 25 .

[0045] By setting the filter screen 24, when the fan 8 is working to absorb external gas through the fixed tube 7, these gases can be filtered. Since valves are installed in the discharge pipe 26 and the feed pipe 25, the feed pipe 25 and the discharge pipe 26 can be opened and closed, and the sealing work in the fermentation tank 1 can be achieved.

[0046] Working principle: First, the raw materials used for liquor fermentation are boiled and cooled, and then the koji is added. Then the feed pipe 25 is opened and poured into the fermentation tank 1 through the feed pipe 25 for fermentation. During the fermentation process, the temperature in the fermentation tank 1 will increase, and the heat will flow upward in the fermentation tank 1. The heat will be transferred to the elastic rubber 11 through the heat-conducting rod 12. After being heated, the elastic rubber 11 will expand and push the circular plate 13 to move, so that the two sets of contact blocks 14 contact and control the motor 4 and the fan 8 to turn on. The fan 8 will extract the external gas and discharge it into the threaded hole 18 through the rotating tube 2 to cool the fermentation tank 1. The gas in the threaded hole 18 will eventually be discharged to the outside world, and the electric The machine 4 will drive the stirring rod 3 to rotate through the rotating tube 2 to stir the raw materials fermented in the fermentation tank 1, diffuse the heat of the raw materials in the fermentation tank 1, and realize heat exchange with the inner wall of the fermentation tank 1. While the rotating tube 2 rotates, the reciprocating threaded tube 15 and the sleeve 16 will drive the connecting plate 17 to rotate and move up and down, thereby improving the uniformity of the temperature on the upper side of the fermentation tank 1 and facilitating the stable heat transfer of the heat-conducting rod 12. When the pressure in the fermentation tank 1 increases, the air pressure will push the movable plate 20 to move upward, so that the pressure relief hole 23 is connected to the mounting tube 9. At this time, the gas in the fermentation tank 1 will be discharged through the pressure relief hole 23, realizing automatic pressure relief.

[0047] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
