Description

Technical Field

[0001] This utility model relates to the field of edible alcohol fermentation technology, and in particular to a horizontal rotary fermentation tank for edible alcohol. Background Technology

[0002] Edible alcohol, as an important basic chemical raw material and food additive, is widely used in liquor brewing, food processing, and pharmaceutical production. In its production process, fermentation is the core step determining alcohol yield and quality, and the performance of fermentation equipment directly affects microbial metabolic efficiency, raw material conversion rate, and production safety. Currently, horizontal fermenters are widely used in the large-scale production of edible alcohol due to their advantages such as small footprint and thorough material mixing.

[0003] In practical applications, traditional horizontal stirred tanks, while capable of a certain degree of material agitation through tank tilting, suffer from simple exhaust systems, often using fixed-aperture exhaust valves. This makes it impossible to dynamically adjust the exhaust pressure according to the gas production rate during fermentation. In the early stages of fermentation, when gas production is low, the fixed exhaust valves can easily lead to backflow of outside air, causing contamination by other microorganisms. Conversely, in the middle stages of fermentation, when gas production is high, untimely exhaust can cause a sudden increase in internal pressure, inhibiting yeast activity and even causing the tank seal to fail. Therefore, to address the problem of existing traditional horizontal stirred tanks using fixed-aperture exhaust valves that cannot dynamically adjust exhaust pressure according to the gas production rate during fermentation, a new type of horizontal rotary fermentation tank for edible alcohol is needed. Utility Model Content

[0004] To address the problem that traditional horizontal mixing tanks in the prior art mostly use exhaust valves with fixed orifice diameters, which cannot dynamically adjust the exhaust pressure according to the gas production rate during the fermentation stage, this application provides a horizontal rotary fermentation tank for edible alcohol. The exhaust mechanism achieves adaptive exhaust through the cooperation of springs and lifting plates. This not only allows for the timely discharge of excess gas to prevent excessive pressure inside the tank, but also seals the channel to prevent the invasion of miscellaneous bacteria when the gas pressure is insufficient, thus providing a stable environment for fermentation. The synergistic effect of the stirring blades and baffles enhances the uniformity of material mixing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A horizontal rotary fermentation tank for edible alcohol includes a support frame, a rotating frame rotatably connected to the top of the support frame, and a tank body fixedly connected to adjacent ends of the rotating frame. An agitator blade is fixedly connected to the left side of the inner wall of the tank, and a baffle is fixedly connected to the right side of the inner wall of the tank. An exhaust pipe is fixedly connected to the inner wall of the baffle. An exhaust hole is provided on the right side of the outer wall of the tank. A fixing ring is rotatably connected to the right side of the outer wall of the tank, and a fixing sleeve is fixedly connected to the top of the fixing ring. An exhaust mechanism is provided on the top side of the inner wall of the fixing sleeve. A material inlet / outlet assembly is provided at the top of the tank body. The bottom right end of the fixing ring is connected to the support frame via a connecting rod.

[0007] As a further improvement of this utility model, the exhaust mechanism includes a fixed plate located on the top side of the inner wall of the fixed sleeve, a sliding rod slidably connected to the inner wall of the fixed plate, a lifting plate fixedly connected to the bottom end of the sliding rod, a spring provided on the outer wall of the sliding rod, and a lifting plate connected to the inner wall of the sliding rod through an adjustment assembly, with the bottom end of the lifting plate located at the top end of the lifting plate.

[0008] As a further improvement of this utility model, one end of the spring is connected to the top of the lifting plate, and the other end of the spring is connected to the bottom of the fixed plate.

[0009] As a further improvement of this utility model, the adjusting component includes a threaded rod located on the inner wall of the slide rod, a knob fixedly connected to the top end of the threaded rod, the bottom end of the knob being rotatably connected to the top end of the fixed plate, a threaded sleeve threadedly connected to the outer wall of the threaded rod, the outer wall of the threaded sleeve being connected to the lifting plate through a connecting rod, and the outer wall of the connecting rod being slidably connected to the inner wall of the slide rod.

[0010] As a further improvement of this utility model, the outer walls of both the fixing plate and the lifting plate are penetrated by through holes.

[0011] As a further improvement of this utility model, the feeding and discharging assembly includes a feeding and discharging pipe located on the top side of the outer wall of the tank. A top cover is rotatably connected to the left side of the outer wall of the feeding and discharging pipe, and the right side of the outer wall of the top cover is connected to the feeding and discharging pipe by a buckle. A sealing ring is provided at the top of the feeding and discharging pipe.

[0012] As a further improvement of this utility model, a discharge chute is provided on the bottom connecting rod of the support frame.

[0013] As a further improvement of this utility model, a motor is mounted on the top of the support frame on the left side via a fixed frame, and the drive end of the motor is fixedly connected to the rotating frame on the left side.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, the exhaust mechanism achieves adaptive exhaust through the cooperation of spring and lifting plate. It can not only discharge excess gas in time to avoid excessive pressure in the tank, but also close the channel to prevent the invasion of miscellaneous bacteria when the gas pressure is insufficient, thus providing a stable environment for fermentation. The synergistic effect of stirring blade and baffle enhances the uniformity of material mixing, allowing microorganisms to have more sufficient contact with the substrate.

[0016] 2. In this utility model, the exhaust pressure is precisely adjusted through the structure of knobs, threaded rods, etc., and the threshold can be flexibly set according to the fermentation gas production characteristics of different raw materials. At the same time, the horizontal rotation design combined with the convenient opening and closing structure of the feeding and discharging components makes the feeding and discharging operations simple. The fixing ring and connecting rod ensure that the exhaust mechanism works stably when the tank rotates, which is suitable for the continuous fermentation needs in large-scale production.

[0030] Example 1:

[0031] like Figures 1-5As shown, a horizontal rotary fermentation tank for edible alcohol includes a support frame 1, a rotating frame 2 rotatably connected to the top of the support frame 1, a tank body 3 fixedly connected to one end of the rotating frame 2, a stirring blade 6 fixedly connected to the left side of the inner wall of the tank body 3, a baffle 7 fixedly connected to the right side of the inner wall of the tank body 3, an exhaust pipe 8 fixedly connected to the inner wall of the baffle 7, an exhaust hole 9 opened on the right side of the outer wall of the tank body 3, a fixing ring 10 rotatably connected to the right side of the outer wall of the tank body 3, a fixing sleeve 11 fixedly connected to the top of the fixing ring 10, a fixing plate 12 provided on the top side of the inner wall of the fixing sleeve 11, an inlet / outlet pipe 4 provided at the top of the tank body 3, and the bottom side of the right end of the fixing ring 10 connected to the support frame 1 through a connecting rod 21.

[0032] Specifically, the support frame 1 serves as the basic support for the equipment, and its bottom is fixed to ensure overall stability. After the motor 23 is started, its drive end drives the left rotating frame 2 to rotate. The two ends of the rotating frame 2 are connected to the support frame 1 and the tank 3 respectively, and can rotate around the rotation point at the top of the support frame 1, thereby driving the tank 3 to rotate horizontally in sync. When the tank 3 rotates, the stirring blade 6 on the left side of the inner wall moves synchronously with the tank 3, continuously turning over the internal materials and breaking up the raw material clumps. At the same time, the fixing ring 10 is connected to the support frame 1 through the connecting rod 21 to ensure that it remains stationary when the tank 3 rotates, providing a stable foundation for subsequent gas discharge.

[0033] The fixed plate 12 is located on the top side of the inner wall of the fixed sleeve 11. The inner wall of the fixed plate 12 is slidably connected to the slide rod 13. The bottom end of the slide rod 13 is fixedly connected to the lifting plate 14. The outer wall of the slide rod 13 is provided with a spring 16. The inner wall of the slide rod 13 is connected to the lifting plate 15 through the adjustment component. The bottom end of the lifting plate 15 is set at the top end of the lifting plate 14. One end of the spring 16 is connected to the top end of the lifting plate 15, and the other end of the spring 16 is connected to the bottom end of the fixed plate 12. The outer walls of the fixed plate 12 and the lifting plate 14 are both through holes. The inlet and outlet pipe 4 is located on the top side of the outer wall of the tank 3. The left side of the outer wall of the inlet and outlet pipe 4 is rotatably connected to the top cover 5. The right side of the outer wall of the top cover 5 is connected to the inlet and outlet pipe 4 through a buckle. The top end of the inlet and outlet pipe 4 is provided with a sealing ring. The bottom connecting rod of the support frame 1 is provided with a discharge groove 22. The top end of the left support frame 1 is mounted with a motor 23 through the fixed frame. The drive end of the motor 23 is fixedly connected to the left rotating frame 2.

[0034] Specifically, the operator opens the top cover 5 of the inlet / outlet pipe 4 in the inlet / outlet assembly. The top cover 5 is opened and closed by rotating on the left side, and the buckle on the right side can be tightly connected to the inlet / outlet pipe 4. The sealing ring at the top of the inlet / outlet pipe 4 can ensure the airtightness when closed, preventing the intrusion of external bacteria. Edible alcohol fermentation raw materials such as starch materials and yeast mixture are added into the tank 3 through the inlet / outlet pipe 4. The top cover 5 is closed and the buckle is fastened to complete the feeding and sealing. The motor 23 at the top of the left support frame 1 is stably installed by the fixing frame. During the fermentation process, the gas produced by the yeast decomposing sugars gradually accumulates in the upper part of the tank 3. The baffle 7 on the right side of the inner wall of the tank 3 and the gas outlet pipe 8 fixed on its inner wall can collect these gases in a directional manner. The gas is introduced into the fixing sleeve 11 at the top of the fixing ring 10 through the gas outlet 9 on the right side of the outer wall of the tank 3. The fixing sleeve 11 provides installation space for the exhaust mechanism and does not rotate with the tank 3. In the exhaust mechanism, the fixed plate 12 is fixed to the top side of the inner wall of the fixed sleeve 11, providing support for the slide rod 13 and the spring 16. When the gas pressure inside the tank is lower than the elastic force of the spring 16, the lifting plate 15 connected to one end of the spring 16 applies downward pressure, causing the lifting plate 14 at the bottom of the slide rod 13 to tightly fit the vent 9, sealing the gas passage and maintaining a slightly enclosed environment inside the tank to prevent bacteria from entering through the exhaust port. When the gas pressure inside the tank rises to exceed the elastic force of the spring 16, the gas pushes the lifting plate 14 to move upward, the slide rod 13 slides along the inner wall of the fixed plate 12, and the spring 16 is compressed. At this time, the lifting plate 14 is aligned with the through hole penetrating the outer wall of the fixed plate 12, and the gas is discharged to the outside through the through hole, realizing automatic exhaust.

[0035] Example 2:

[0036] As one of the optimized structural designs for Example 1, such as Figures 1-5 As shown, a threaded rod 18 is located on the inner wall of the slide rod 13. A knob 17 is fixedly connected to the top of the threaded rod 18. The bottom of the knob 17 is rotatably connected to the top of the fixed plate 12. A threaded sleeve 19 is threadedly connected to the outer wall of the threaded rod 18. The outer wall of the threaded sleeve 19 is connected to the lifting plate 15 through a connecting rod 20. The outer wall of the connecting rod 20 is slidably connected to the inner wall of the slide rod 13.

[0037] Specifically, to adapt to the gas production rate at different fermentation stages, such as low gas production in the early stage and high gas production in the middle stage, the exhaust pressure threshold can be adjusted through the regulating component. Rotating knob 17 in the regulating component connects the bottom of knob 17 to the top of fixed plate 12, causing the threaded rod 18 below to rotate synchronously. The threaded sleeve 19 on the outer wall of threaded rod 18 moves up and down along threaded rod 18 due to the threaded engagement, which in turn moves lifting plate 15 via connecting rod 20. Connecting rod 20 slides along the inner wall of slide rod 13, ensuring smooth movement of lifting plate 15. When lifting plate 15 moves downward, spring 16 is compressed, increasing the preload and raising the required tank pressure threshold for exhaust; conversely, when lifting plate 15 moves upward, the preload of spring 16 decreases, lowering the exhaust threshold. This structure allows for precise adjustment of the exhaust pressure to suit the gas production characteristics throughout the entire fermentation cycle.

[0038] Working principle: Open the top cover 5 and add fermentation raw materials into the tank 3 through the inlet / outlet pipe 4. Close the top cover 5 and fasten the buckle. Then start the motor 23. The motor 23 drives the left rotating frame 2 to rotate, causing the tank 3 to rotate synchronously with the rotating frame 2. When the tank 3 rotates, the stirring blade 6 on the left side of the inner wall stirs and agitates the materials. During the fermentation process, the alcohol and gas produced by the yeast decomposes sugars will gradually accumulate in the upper part of the tank 3. After being collected through the gas outlet pipe 8 on the inner wall of the baffle 7, they enter the fixed sleeve 11 through the gas outlet 9 on the right side of the tank 3. When the gas pressure inside the tank is lower than the elastic force of the spring 16, the lifting plate 14 closes the gas outlet 9 under the pressure of the spring 16. Maintaining a slightly enclosed environment inside the tank, when the gas pressure rises above the spring force of spring 16, the gas pushes the lifting plate 14 upward, the slide rod 13 slides along the fixed plate 12, the spring 16 is compressed, and the gas is discharged to the outside through the through holes of the lifting plate 14 and the fixed plate 12. If it is necessary to adjust the exhaust pressure, the knob 17 can be rotated, and the lifting plate 15 can be moved by the cooperation of the threaded rod 18 and the threaded sleeve 19, changing the preload of spring 16, so as to achieve precise control of the exhaust threshold. After fermentation is completed, the motor 23 is turned off, the tank body 3 is rotated until the inlet and outlet pipes 4 face downward, the top cover 5 is opened, and the fermentation products are discharged through the inlet and outlet pipes 4 to the discharge trough 22 to complete the collection.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
