Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, and in particular to a fermentation device for corn fermentation powder. Background Technology

[0002] Fermentation is a biochemical process in which microorganisms (such as bacteria, yeast, and mold) utilize organic matter (such as sugars, starches, and proteins) under anaerobic or microaerobic conditions to carry out metabolic activities, producing energy, carbon dioxide, alcohol, organic acids, and other metabolic products. In food processing, fermentation plays several important roles. For example, during fermentation, microorganisms can transform complex macromolecular organic matter into simpler, more easily absorbed small molecules. Furthermore, the metabolic products produced during fermentation, such as alcohol and organic acids, can impart unique flavors to food. Additionally, microorganisms can synthesize vitamins and amino acids during fermentation, enhancing the nutritional value of food. Fermentation equipment is often required for fermentation processing.

[0003] Fermentation is widely used in the food industry. Fermentation equipment is also used in the fermentation and processing of corn baking powder, as shown below.

[0004] A search revealed a patent with authorization announcement number CN219409698U, which discloses a high-efficiency corn yeast fermentation device. The device includes an outer barrel containing an inner barrel fixed inside. A cavity is formed between the inner wall of the outer barrel and the outer wall of the inner barrel. Electric heating tubes are equidistantly arranged within this cavity. A fermentation chamber is formed between the inner wall of the inner barrel and the bottom inner wall of the outer barrel. This invention, by equidistantly arranging electric heating tubes within the cavity between the outer and inner barrels, heats the fermentation chamber when the air temperature is cold, thereby increasing the fermentation rate. The device utilizes positioning blocks, positioning holes, locking holes, a U-shaped plate, a first spring, a lever, and a locking rod to conveniently and quickly fix the cover plate to the ring plate or remove it from the ring plate. Furthermore, the device incorporates a connecting pipe, partition, frustum hole, frustum block, fixing block, T-shaped rod, and a second spring to automatically vent air when the air pressure inside the fermentation chamber is high, eliminating the need for manual opening of the cover plate, thus providing greater convenience.

[0005] However, the aforementioned corn fermentation equipment still has the following areas for improvement. For example, although it can ensure a suitable fermentation temperature in cold weather by heating the barrel wall, thereby improving fermentation efficiency, the heating process only gradually heats the material inside the barrel from the wall inwards. This results in the material near the inner wall receiving better heating, while the material near the center of the inner barrel receives poorer heating. Consequently, the overall fermentation efficiency of the material is uneven, reducing the fermentation effect and production quality. Therefore, its structure needs improvement, and its practicality needs to be enhanced. Utility Model Content

[0006] This utility model discloses a fermentation device for corn fermentation powder. It features a uniform heating mechanism, allowing materials to be added to the fermentation tank in cold weather. After the tank lid is closed and locked, multiple first and second heating tubes are activated. The first heating tubes generate heat from the tank wall, transferring heat from the outside in to the materials inside. The second heating tubes, in conjunction with heat-conducting oil, transfer heat to the rotating sleeve shaft, which then heats the materials inside the fermentation tank from the inside out. Simultaneously, a speed-reducing motor drives the rotating sleeve shaft and two sets of stirring rods to rotate slowly. Since the stirring rods absorb heat from the rotating sleeve shaft and transfer it to the materials, the two sets of stirring rods can better and more evenly distribute heat to the materials throughout the fermentation tank. Overall, this significantly improves the heating effect, efficiency, and uniformity of the materials inside the fermentation tank, thereby effectively improving the fermentation process and production quality. In summary, this solves the problems in the background technology.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model discloses a fermentation device for corn yeast, including a base, on the top of which a fermentation tank is fixedly mounted, and on the top of the fermentation tank is a lid, the inside of which has two through positioning grooves.

[0009] A uniform heating mechanism includes a first heating tube, a second heating tube, a rotating sleeve shaft, a reduction motor, and a transmission shaft. Multiple first heating tubes are embedded and fixedly installed within the inner walls of the fermentation tank. The second heating tube penetrates the bottom of the fermentation tank and extends into its interior, being fixedly connected to the bottom. The rotating sleeve shaft is rotatably mounted on the inner bottom surface of the fermentation tank via a rotating connector, and has a cavity inside. The rotating sleeve shaft is located outside the second heating tubes. The internal dimensions of the rotating sleeve shaft are larger than the external dimensions of the second heating tube. The space between the inside of the rotating sleeve shaft and the outside of the second heating tube is filled with heat-conducting oil. A rectangular transmission groove is provided at the top of the rotating sleeve shaft. The transmission groove is not connected to the internal cavity of the rotating sleeve shaft. Two sets of stirring rods are provided on the outside of the rotating sleeve shaft. The reduction motor is fixedly installed on the top of the bucket lid. The output end of the reduction motor extends through the bucket lid to the bottom of the bucket lid. The top of the transmission shaft is connected to the output end of the reduction motor. A transmission block is fixedly connected to the bottom of the transmission shaft. The transmission block matches and engages with the transmission groove.

[0010] Locking connection mechanism; the fermentation tank and the lid are connected and fixed by the locking connection mechanism.

[0011] Furthermore, both the rotating sleeve shaft and the stirring rod are made of aluminum alloy, and the multiple first heating tubes are arranged in a ring array.

[0012] Furthermore, the two sets of stirring rods are designed with staggered vertical positions.

[0013] Furthermore, two first handles are fixedly connected to the top of the bucket lid, and second handles are fixedly connected to both sides of the fermentation bucket.

[0014] Furthermore, the top of the bucket lid is provided with two automatic vent valves, and the bottom of the bucket lid is fitted with a sealing gasket layer.

[0015] Furthermore, the output end of the geared motor is sealed at the point where it passes through the barrel lid, and the second heating tube is also sealed at the point where it passes through the fermentation barrel.

[0016] Furthermore, the locking connection mechanism includes a positioning block, a fixing block, and a locking knob. The locking connection mechanism has two sets. The two positioning blocks are fixedly installed on both sides of the fermentation tank near its top, and the positioning blocks pass through the positioning groove. The positioning blocks have a through limiting groove inside. The two fixing blocks are fixedly installed on the top of the tank lid. One end of the locking knob passes through the fixing block by screwing, and the locking knob matches and engages with the limiting groove.

[0017] The present invention has the following advantages over the prior art:

[0018] 1. This technical solution incorporates a uniform heating mechanism, allowing materials to be added to the fermentation tank in cold weather, the tank lid to be closed and locked, and then the uniform heating mechanism heats the materials inside the fermentation tank by transferring heat from the outside to the inside, from the inside to the outside, and rotating to uniformly transfer heat. In summary, this greatly improves the heating effect, heating efficiency, and heating uniformity of the materials inside the fermentation tank, thereby effectively improving the fermentation processing effect and production quality of the materials, and making the device highly practical.

[0019] 2. This technical solution incorporates a uniform heating mechanism, which allows for both rapid and uniform heating of the materials and slow agitation of the materials inside the fermentation tank. This agitation helps to evenly distribute the yeast and moisture, promoting fermentation. Simultaneously, agitation helps to release carbon dioxide produced during fermentation, preventing gas accumulation that could lead to incomplete fermentation or unpleasant taste, thus further improving the practicality of the device.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Reference Figures 1-7 A fermentation device for corn baking powder includes a base 1, a fermentation tank 2 is fixedly mounted on the top of the base 1, a tank cover 3 is mounted on the top of the fermentation tank 2, and two through positioning grooves 4 are opened inside the tank cover 3.

[0032] The uniform heating mechanism 5 includes a first heating tube 501, a second heating tube 502, a rotating sleeve shaft 503, a reduction motor 504, and a transmission shaft 505. Multiple first heating tubes 501 are embedded and fixedly installed in the inner walls of the fermentation tank 2. The second heating tubes 502 penetrate the bottom of the fermentation tank 2 and extend into its interior, being fixedly connected to the bottom. The rotating sleeve shaft 503 is rotatably mounted on the inner bottom surface of the fermentation tank 2 via a rotating connector 506, and has a cavity inside. The rotating sleeve shaft 503 is located outside the second heating tubes 502, and its internal dimensions are larger than those of the second heating tubes 502. The fermentation tank 2 is surrounded by a heat-conducting oil 507 between the interior of the rotating sleeve shaft 503 and the exterior of the second heating tube 502. A rectangular transmission groove 508 is provided on the top of the rotating sleeve shaft 503. The transmission groove 508 is not connected to the internal cavity of the rotating sleeve shaft 503. Two sets of stirring rods 509 are provided on the outside of the rotating sleeve shaft 503. The reduction motor 504 is fixedly installed on the top of the lid 3. The output end of the reduction motor 504 extends through the lid 3 to the bottom of the lid 3. The top of the transmission shaft 505 is connected to the output end of the reduction motor 504. The bottom of the transmission shaft 505 is fixedly connected to the transmission block 510, which matches and engages with the transmission groove 508. A locking connection mechanism 6 is used to connect and fix the fermentation tank 2 and the lid 3.

[0033] Both the rotating sleeve shaft 503 and the stirring rod 509 are made of aluminum alloy. Multiple first heating tubes 501 are arranged in a ring array. The two sets of stirring rods 509 are arranged in a staggered pattern. Two first handles 7 are fixedly connected to the top of the lid 3, and second handles 8 are fixedly connected to both sides of the fermentation tank 2. Two automatic exhaust valves 9 are located on the top of the lid 3, and a sealing gasket 10 is fitted to the bottom of the lid 3. The output end of the geared motor 504 is sealed at the point where it passes through the lid 3, and the second heating tube 502 passes through the fermentation tank 2. Similarly, it is sealed; the locking connection mechanism 6 includes a positioning block 601, a fixing block 602 and a locking knob 603. The locking connection mechanism 6 has two sets. The two positioning blocks 601 are fixedly installed on both sides of the fermentation tank 2 near its top, and the positioning blocks 601 pass through the positioning groove 4. The interior of the positioning blocks 601 has a through limiting groove 604. The two fixing blocks 602 are fixedly installed on the top of the tank cover 3. One end of the locking knob 603 passes through the fixing block 602 by screwing, and the locking knob 603 matches and engages with the limiting groove 604.

[0034] In practical implementation, during cold weather, materials can be added to fermentation tank 2, and the lid 3 can be closed and locked securely. Then, multiple first heating tubes 501 and second heating tubes 502 can be activated. The multiple first heating tubes 501 generate heat from the tank wall of fermentation tank 2, transferring heat from the outside to the inside to heat the materials inside fermentation tank 2. When the second heating tubes 502 generate heat, they can work in conjunction with heat transfer oil 507 to transfer heat to the rotating sleeve shaft 503, which then heats the materials inside fermentation tank 2 from the inside to the outside. Simultaneously, the speed is reduced. When the motor 504 operates, it works with the drive shaft 505, drive block 510, and drive groove 508 to drive the rotating sleeve shaft 503 and two sets of stirring rods 509 to rotate slowly. Since the stirring rods 509 can absorb the heat on the rotating sleeve shaft 503 and transfer it to the material, the two sets of stirring rods 509 can better and more evenly transfer the heat to the material in various positions inside the fermentation tank 2 when they rotate. In summary, this can greatly improve the heating effect, heating efficiency, and heating uniformity of the material inside the fermentation tank 2, thereby effectively improving the fermentation processing effect and production quality of the material.

[0035] While the material is heated evenly and quickly, the material inside the fermentation tank 2 can be slowly stirred by two sets of rotating stirring rods 509. Stirring the material can help to evenly distribute the yeast and water, promote fermentation, and at the same time, stirring can help release the carbon dioxide produced during fermentation, avoiding gas accumulation that could lead to incomplete fermentation or unpleasant taste.

[0036] The rotating sleeve shaft 503 and the stirring rod 509 are both made of aluminum alloy to ensure that they have good thermal conductivity. The multiple first heating tubes 501 are arranged in a ring array to uniformly heat the material inside the fermentation tank 2 from the outside to the inside.

[0037] The first handle 7 is for the convenience of staff to install, remove and move the bucket lid 3, and the second handle 8 is for the convenience of staff to tilt and move the fermentation bucket 2.

[0038] The top of the lid 3 is equipped with two automatic exhaust valves 9 to automatically release air when the internal pressure of the fermentation tank 2 is high. These automatic exhaust valves 9 can be referenced from the automatic exhaust valves 9 of pressure cookers. This is an existing technology application and will not be elaborated on here. The bottom of the lid 3 is fitted with a sealing gasket 10 to improve the sealing between the lid 3 and the fermentation tank 2.

[0039] The output end of the geared motor 504 is sealed at the point where it passes through the lid 3, and the second heating pipe 502 is also sealed at the point where it passes through the fermentation tank 2, both in order to improve the sealing performance inside the fermentation tank 2.

[0040] The lid 3 can be disassembled by rotating the two limit knobs to separate it from the limit groove 604. During installation, the positioning groove 4 is aligned with the positioning plate and inserted into the lid 3 until the bottom of the lid 3 is in contact with the top of the fermentation tank 2. Then, the two limit knobs can be rotated to match and engage with the limit groove 604, thus completing the installation and locking connection of the lid 3. The operation is simple.

[0041] It is understandable that the second heating tube 502 is detachably fixed to the fermentation tank 2 so that the second heating tube 502 can be removed periodically to replace the heat transfer oil 507.

[0042] Working principle: In cold weather, materials can be added to fermentation tank 2, and the lid 3 can be closed and locked. Then, multiple first heating tubes 501 and second heating tubes 502 can be activated. The first heating tubes 501 generate heat from the tank wall of fermentation tank 2, transferring heat from the outside to the inside of the fermentation tank 2 to heat the materials inside. When the second heating tubes 502 generate heat, they can work with heat transfer oil 507 to transfer heat to the rotating sleeve shaft 503, which then heats the materials inside fermentation tank 2 from the inside out. At the same time, the reduction motor 504 works, working with the transmission shaft 505, transmission block 510, and transmission groove 508 to drive the rotating sleeve shaft 503 and two sets of stirring rods 509 to rotate slowly. Because the stirring rods 509 can... The rotating sleeve shaft 503 absorbs and transfers heat to the material. Therefore, when the two sets of stirring rods 509 rotate, they can better and more evenly transfer heat to the material in various positions inside the fermentation tank 2. In summary, this can greatly improve the heating effect, heating efficiency, and heating uniformity of the material inside the fermentation tank 2, thereby effectively improving the fermentation processing effect and production quality of the material. While the material is heated evenly and quickly, the two sets of rotating stirring rods 509 can also slowly stir the material inside the fermentation tank 2. Stirring the material can help to evenly distribute the yeast and water, promote fermentation, and at the same time, stirring can also help release the carbon dioxide produced during fermentation, avoiding gas accumulation that could lead to incomplete fermentation or unpleasant taste.

Clearly, many modifications and variations can be made based on the content of this specification.
