[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0037] As described in the background art, the prior art has deficiencies. In order to solve the above technical problems, the present application proposes a fermentation device and a fermentation method for soy sauce brewing.

[0038] Example 1:

[0039] See also Figure 1 - Figure 8 A fermentation device includes a fermentation tank 1, a distillation mechanism 2 is installed at the bottom of the fermentation tank 1, a stirring mechanism 3 is installed inside the fermentation tank 1, and a circulation mechanism 4 is installed inside the fermentation tank 1;

[0040] The distillation mechanism 2 includes a water vapor cooling chamber 25, which is disposed inside the fermentation tank 1. A connecting turntable 24 is rotatably mounted at the bottom of the water vapor cooling chamber 25. A distilled water storage chamber 26 and a raw material storage chamber 27 are provided inside the connecting turntable 24. A baffle is provided between the distilled water storage chamber 26 and the raw material storage chamber 27 to separate them. The interior of the connecting turntable 24 is connected to the circulation mechanism 4. The stirring mechanism 3 extends through the center of the connecting turntable 24 into the interior of the fermentation tank 1.

[0041] The interior of the fermentation tank 1 stores and ferments the fermentation raw materials, the stirring mechanism 3 can stir the fermentation raw materials inside the fermentation tank 1, the distillation mechanism 2 can heat the water inside to evaporate it, and the evaporated water vapor moves upward along the distillation mechanism 2, the water vapor cooling bin 25 can cool the water vapor to condense it into pure water, the circulation mechanism 4 can drive the cooling water inside the water vapor cooling bin 25 to circulate inside the side wall of the fermentation tank 1, and the cooling water inside the water vapor cooling bin 25 can maintain the internal temperature of the fermentation tank 1 constant when moving inside the circulation mechanism 4, and the stirring mechanism 3 can control the distilled water storage bin 26 and the raw material storage bin 27 to add fermentation raw materials and distilled pure water to the fermentation tank 1 by adjusting the rotation direction.

[0042] During operation, the fermentation raw materials are first placed into the fermentation tank 1. During the fermentation process, the distillation mechanism 2 can heat the pure water stored inside. The evaporated water vapor moves upward along the distillation mechanism 2. When the water vapor moves into the water vapor cooling bin 25, the cooling water inside the water vapor cooling bin 25 can condense the water vapor into liquid water by lowering its temperature. The condensed liquid water can enter the distilled water storage bin 26. During the liquefaction process of the water vapor inside the distillation mechanism 2, a large amount of heat can be released, so that the temperature of the cooling water inside the water vapor cooling bin 25 increases, and the circulation mechanism 4 can drive the cooling water inside the water vapor cooling bin 25 to flow along the side wall of the fermentation tank 1. The temperature of the cooling water decreases during its movement and the cooling water returns to the inside of the water vapor cooling bin 25. When the stirring mechanism 3 rotates forward, the turntable 24 can be connected to rotate forward and the fermentation raw materials inside the fermentation tank 1 can be stirred to make the fermentation mixing more uniform. When the stirring mechanism 3 rotates reversely, the turntable 24 can be driven to rotate reversely and the distilled water storage bin 26 and the raw material storage bin 27 can be controlled to add fermentation raw materials and distilled pure water to the inside of the fermentation tank 1. By distilling the pure water inside the distillation mechanism 2 and then adding it to the inside of the fermentation tank 1, it can effectively prevent the pure water from entering the fermentation tank 1 after being contaminated from the outside and infecting the fermentation raw materials inside the fermentation tank 1.

[0043] Example 2:

[0044] The difference from the above embodiment is that, please refer to Figure 4 - Figure 8The distillation mechanism 2 includes a pure water storage bin 21, which is installed at the bottom of the fermentation tank 1. The top of the pure water storage bin 21 is connected to a water vapor delivery pipe 22, and the top of the water vapor delivery pipe 22 is connected to a water vapor condenser 23. The inner side of the water vapor condenser 23 is connected to the connecting turntable 24. The bottom of the raw material storage bin 27 is respectively provided with a distilled water outlet 28 and a raw material outlet 29, and the distilled water outlet 28 and the raw material outlet 29 are both connected to the outside of the stirring mechanism 3.

[0045] The interior of the purified water storage tank 21 is connected to the interior of the water vapor condenser 23 through a plurality of water vapor delivery pipes 22. The spiral structure of the water vapor condenser 23 and the outlet of the water vapor condenser 23 are connected to the distilled water storage tank 26 inside the connecting turntable 24;

[0046] The pure water storage tank 21 can heat the water stored inside to evaporate it, the water vapor delivery pipe 22 can allow the evaporated water vapor to enter the water vapor condenser 23, and the pure water inside the water vapor cooling tank 25 can cool the water vapor inside the water vapor condenser 23 into pure water and enter the distilled water storage tank 26.

[0047] The interior of the distilled water storage bin 26 is connected to the interior of the fermentation tank 1 via the distilled water outlet 28. The interior of the raw material storage bin 27 is connected to the interior of the fermentation tank 1 via the raw material outlet 29. The exterior of the stirring mechanism 3 is engaged with the distilled water outlet 28 and the raw material outlet 29. The stirring mechanism 3 can control the closing of the distilled water outlet 28 and the raw material outlet 29.

[0048] When the stirring mechanism 3 rotates forward, it can drive the connecting turntable 24 to rotate forward and close the distilled water outlet 28 and the raw material outlet 29. When the stirring mechanism 3 rotates backward, it can drive the connecting turntable 24 to rotate backward and open the distilled water outlet 28 and the raw material outlet 29.

[0049] The stirring mechanism 3 includes a stirring motor 31 and a motor mounting base 32. The motor mounting base 32 is fixedly mounted on the top of the fermentation tank 1. The stirring motor 31 is mounted on the top of the motor mounting base 32. The driving point of the stirring motor 31 is connected to the motor rotating rod 33. The outside of the motor rotating rod 33 is connected to the stirring blade 34. The top of the stirring blade 34 is installed with an upper connecting plate 35. The bottom of the stirring blade 34 is connected with a lower connecting plate 36. The outside of the upper connecting plate 35 is installed with a discharge sealing plate 37.

[0050] The top of the motor rotating rod 33 passes through the top of the fermentation tank 1 and the interior of the distillation mechanism 2 and is connected to the driving end of the stirring motor 31. The exterior of the motor rotating rod 33 is respectively connected to the stirring blade 34, the upper connecting plate 35 and the lower connecting plate 36.

[0051] The stirring motor 31 can drive the motor rotating rod 33 to rotate. When the motor rotating rod 33 rotates, it can drive the stirring blades 34, the upper connecting plate 35 and the lower connecting plate 36 to rotate synchronously.

[0052] The outer portion of the upper connecting plate 35 is connected to the inner portion of the distilled water outlet 28 and the raw material outlet 29 respectively through the discharge sealing plate 37. The outer portion of the discharge sealing plate 37 is slidably connected to the inner portion of the distilled water outlet 28 and the raw material outlet 29. The outer portion of the discharge sealing plate 37 is provided with a protrusion.

[0053] When the upper connecting plate 35 rotates forward, the discharge sealing plate 37 can seal the distilled water outlet 28 and the raw material outlet 29 and drive the connecting turntable 24 to rotate forward through the distilled water outlet 28 and the raw material outlet 29. When the upper connecting plate 35 rotates reversely, the discharge sealing plate 37 releases the seal on the distilled water outlet 28 and the raw material outlet 29. The discharge sealing plate 37 is engaged with the distilled water outlet 28 and the raw material outlet 29 through the external protrusion and drives the connecting turntable 24 to rotate reversely.

[0054] During operation, the pure water storage bin 21 can heat the pure water stored inside and evaporate it. The evaporated water vapor moves upward along the water vapor delivery pipe 22 and enters the inside of the water vapor condenser 23, and the water vapor condenser 23 is immersed in the cooling water. The water vapor can be liquefied into pure water when moving inside the water vapor condenser 23. The liquefied pure water enters the inside of the distilled water storage bin 26. The heat released when the water vapor is liquefied will also increase the temperature of the cooling water inside the water vapor cooling bin 25. When the stirring motor 31 drives the motor rotating rod 33 to rotate forward, the motor rotating rod 33 drives the stirring blade 34, the upper connecting plate 35 and the lower connecting plate 36 to rotate forward synchronously. When the upper connecting plate 35 rotates forward, the discharge sealing plate 37 can seal the distilled water outlet 28 and the raw material outlet 29, and can also drive the connecting turntable 24 to rotate forward through the connection between the discharge sealing plate 37 and the distilled water outlet 28 and the raw material outlet 29. When the stirring blade 34 rotates forward, The stirring motor 31 drives the motor rotating rod 33 to rotate in the opposite direction, and the motor rotating rod 33 drives the stirring blade 34, the upper connecting plate 35 and the lower connecting plate 36 to rotate in the opposite direction synchronously. When the upper connecting plate 35 rotates in the opposite direction, the discharge sealing plate 37 can be driven to release the seal of the distilled water outlet 28 and the raw material outlet 29. At this time, the discharge sealing plate 37 is engaged with the inner part of the distilled water outlet 28 and the raw material outlet 29 through the external protrusion, and drives the connecting turntable 24 to rotate in the opposite direction when the upper connecting plate 35 rotates in the opposite direction. When the connecting turntable 24 rotates in the opposite direction, the fermentation raw materials and distilled pure water can be evenly added to the fermentation tank 1. The opening and closing of the distilled water outlet 28 and the raw material outlet 29 are controlled by the rotation direction of the upper connecting plate 35. When the distilled water outlet 28 and the raw material outlet 29 add the fermentation raw materials and distilled pure water to the fermentation tank 1, the connecting turntable 24 rotates at a constant speed, which can make the fermentation raw materials in the fermentation tank 1 more evenly mixed.

[0055] Example 3:

[0056] The difference from the above embodiment is that, please refer to Figure 1 - Figure 3 The circulation mechanism 4 includes a circulating water pump 41, which is installed on the top of the fermentation tank 1. The feed end of the circulating water pump 41 is connected to an inlet pipe 42, and the discharge end of the circulating water pump 41 is connected to an outlet pipe 43. The other end of the outlet pipe 43 is connected to a circulation pipe 44, and the other end of the circulation pipe 44 is connected to a return pipe 45. The other end of the return pipe 45 is connected to the interior of the water vapor cooling bin 25.

[0057] The circulating water pump 41 is connected to the interior of the water vapor cooling bin 25 through the water inlet pipe 42. The circulating water pump 41 is connected to the opening at the bottom of the circulating pipe 44 through the water outlet pipe 43. The opening at the top of the circulating pipe 44 is connected to the interior of the water vapor cooling bin 25 through the return pipe 45. The circulation mechanism 4 is arranged in layers in an annular shape and installed inside the side wall of the fermentation tank 1.

[0058] The circulating water pump 41 can drive the cooling water in the water vapor cooling chamber 25 into the circulation pipe 44 . The cooling water in the circulation pipe 44 can also flow back to the water vapor cooling chamber 25 through the return pipe 45 .

[0059] During operation, the circulating water pump 41 can pump the cooling water inside the water vapor cooling bin 25 into the circulating pipe 44. After entering the circulating pipe 44, the cooling water moves downward layer by layer along the circulating pipe 44. During the movement of the cooling water along the circulating pipe 44, the temperature inside the fermentation tank 1 can be kept constant. As the cooling water inside the circulation mechanism 4 gradually increases, the cooling water inside the circulating pipe 44 enters the reflux pipe 45 and returns to the water vapor cooling bin 25 along the reflux pipe 45. When the cooling water temperature rises, it is pumped into the side wall of the fermentation tank 1, and after the cooling water temperature drops, it is returned to the water vapor cooling bin 25. This ensures the cooling efficiency of the water vapor inside the water vapor condenser 23 and keeps the fermentation temperature inside the fermentation tank 1 constant.

[0060] Example 4:

[0061] A fermentation method for soy sauce brewing, using a fermentation device as described in Examples 1 to 3, comprises the following steps:

[0062] During operation, the fermentation raw materials are first placed into the fermentation tank 1;

[0063] The purified water is then heated in the distillation mechanism 2 to evaporate, and the evaporated water vapor is cooled in the water vapor cooling chamber 25 and then enters the interior of the distilled water storage chamber 26;

[0064] The cooling water is driven to move along the side wall of the fermentation tank 1 by the circulation mechanism 4, so that the temperature inside the fermentation tank 1 is kept constant;

[0065] When the distillation mechanism 2 rotates forward, the fermentation raw materials inside the fermentation tank 1 can be stirred. When the distillation mechanism 2 rotates backward, the fermentation raw materials and distilled purified water can be heated inside the fermentation tank 1 through the distilled water outlet 28 and the raw material outlet 29.
