Description

Technical Field

[0001] This utility model relates to fermentation device technology, specifically to a fermentation device for brewing. Background Technology

[0002] Brewing utilizes the activity of microorganisms under anaerobic conditions to transform starchy raw materials such as sorghum, corn, wheat, and rice into alcoholic beverages. The brewing process requires fermentation of the starchy raw materials, specifically by Aspergillus flavus breaking down starch into sugar, which is then converted into alcohol by yeast. To ensure the quality of the brewed beverage, this fermentation process is usually carried out using specialized fermentation equipment. However, in existing brewing fermentation equipment, uneven heating of the fermenting material during fermentation often significantly impacts the quality and taste of the beverage.

[0003] To address the aforementioned issues, Chinese patent CN218372203U discloses a fermentation apparatus for brewing, comprising an inner fermentation tank, an insulation chamber, and a heating component. A first and second heating rod form a uniform heating frame covering a certain space within the inner fermentation tank, contacting the fermenting mash. Combined with the agitation of a spiral stirring rod, the material is continuously transferred from the bottom to the top, resulting in more even heating of the fermented material. However, during the stirring process, the spiral stirring rod can easily cause material to accumulate inside the rod, preventing sufficient contact between the material and the fermentation liquid. This leads to incomplete fermentation in certain areas and may also affect microbial activity due to poor contact, thereby impacting the efficiency of the entire fermentation process and reducing alcohol yield and quality.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a fermentation device for brewing, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A fermentation apparatus for brewing includes a fermentation tank with a fermentation cover at its top. A feed pipe extends through the top of the fermentation cover, and a pressure sensor penetrating the fermentation cover is located on one side of the feed pipe. An exhaust pipe penetrating the fermentation cover is located on one side of the pressure sensor. A temperature sensor is installed on the inner wall of the fermentation tank. A stirring mechanism penetrating the fermentation cover is installed inside the fermentation tank to ensure thorough mixing of the materials and fermentation liquid. A discharge assembly extends through the bottom of the fermentation tank to prevent blockage during the discharge process.

[0008] Furthermore, to achieve sufficient contact between the material and the fermentation broth, the material is cut, dispersed, and mixed in different layers by the agitation action of several arc-shaped rods, increasing the relative movement between the materials and further promoting contact between the material and the fermentation broth, thus improving fermentation efficiency. Simultaneously, the conical structure of several conical blocks effectively breaks down the adhesion between materials, reducing the possibility of material accumulation and generating more turbulence, which helps in the mixing of the material and the fermentation broth, and breaks up any air bubbles that may form during stirring, preventing them from affecting the uniform distribution of the material and the fermentation process. The stirring mechanism includes a motor that runs through the top of the fermentation lid, a hollow column on the outside of the motor, a rotating cylinder connected to the bottom of the motor, a bearing connecting the top of the rotating cylinder to the hollow column, a bearing connecting the inner wall of the hollow column to the motor, and a fixing plate symmetrically arranged at the top of the hollow column to connect with the fermentation lid. The outer side of the cylinder has several grooves, and the inside of the grooves has several sliding columns. The end of the sliding column away from the groove is equipped with a connecting rod, and the bottom of the side of the connecting rod away from the groove is equipped with a connecting column that penetrates through the rotating cylinder. The connecting column and the rotating cylinder are connected by a bearing in three phases. A mixing component is provided at one end of the connecting column to realize the turning of materials. The groove includes several arc-shaped grooves 1 opened on the outer side of the hollow column. Arc-shaped grooves 2 are provided at the bottom of one side of the arc-shaped grooves 1. One end of the arc-shaped grooves 1 and one end of the arc-shaped grooves 2 are connected by an inclined groove. The mixing component includes a rotating blade provided at one end of the connecting column. Several arc-shaped rods 1 are provided at the top of the rotating blade, and several arc-shaped rods 2 are provided at the bottom of the rotating blade. Several conical blocks are provided on both sides of the rotating blade. The arc-shaped rods 1 are staggered and rectangularly distributed at the top of the rotating blade. The arc-shaped rods 2 are staggered and rectangularly distributed at the bottom of the rotating blade. The bending directions of the arc-shaped rods 1 and 2 are opposite.

[0009] Furthermore, to prevent blockage during discharge, the pre-interception of fermentation residue by several intercepting columns reduces the probability of filter pipe blockage. The further filtration by the filter pipe improves the quality of the liquor flowing from the discharge pipe. If the filter pipe becomes blocked, it can be removed from the discharge pipe by rotating it, facilitating cleaning by operators and ensuring smooth subsequent discharge. The discharge assembly includes a discharge pipe located at the bottom of the fermentation tank, with a water valve running through its interior. One end of the discharge pipe is connected to a filter pipe, which contains several intercepting columns. The discharge pipe and filter pipe are connected by threads. The intercepting columns are evenly arranged and circumferentially distributed inside the filter pipe, and each intercepting column is arc-shaped.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through the coordinated arrangement of a fermentation tank, fermentation cover, feed pipe, pressure sensor, exhaust pipe, temperature sensor, stirring mechanism, and discharge component, not only enables the fermentation of starch raw materials, but also avoids material accumulation, ensuring that the material and fermentation liquid are fully mixed and in contact, preventing incomplete local fermentation, guaranteeing microbial activity, thereby ensuring the efficiency of the entire fermentation process, and thus improving the alcohol yield and quality.

[0012] 2. Through the stirring mechanism, the material in different layers is cut, dispersed and mixed by the tumbling action of several arc-shaped rods, increasing the relative movement between the materials, further promoting the contact between the materials and the fermentation liquid, and improving the fermentation efficiency. At the same time, the conical structure of several conical blocks effectively breaks the adhesion between the materials, reduces the possibility of material accumulation, and generates more turbulence, which helps to mix the materials with the fermentation liquid and breaks up any air bubbles that may be formed during the stirring process, preventing air bubbles from affecting the uniform distribution of the materials and the fermentation process.

[0013] 3. The discharge assembly reduces the probability of filter tube blockage by intercepting fermentation residues in advance through several intercepting columns. The further filtration by the filter tube improves the quality of the wine flowing out of the discharge tube. If the filter tube becomes blocked, it can be removed from the discharge tube by rotating it, making it easy for operators to clean the filter tube and ensuring the smoothness of subsequent discharge.

[0029] According to an embodiment of the present invention, a fermentation apparatus for brewing is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-11 As shown, the brewing fermentation device according to an embodiment of the present invention includes a fermentation tank 1, a fermentation cover 2 that cooperates with the fermentation tank 1, a feed pipe 3 that penetrates the top of the fermentation cover 2, a pressure sensor 4 that penetrates the fermentation cover 2 on one side of the feed pipe 3, and an exhaust pipe 5 that penetrates the fermentation cover 2 on one side of the pressure sensor 4; a temperature sensor 6 that is installed on the inner wall of the fermentation tank 1; a stirring mechanism 7 that penetrates the fermentation cover 2 is installed inside the fermentation tank 1 to achieve full mixing of materials and fermentation liquid; and a discharge assembly 8 that penetrates the bottom of the fermentation tank 1 to prevent blockage during the discharge process.

[0031] By utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of fermentation tank 1, fermentation cover 2, feed pipe 3, pressure sensor 4, exhaust pipe 5, temperature sensor 6, stirring mechanism 7 and discharge component 8, this utility model can not only achieve the fermentation treatment of starch raw materials, but also avoid material accumulation, so that the material and fermentation liquid are fully mixed and in contact, avoid incomplete local fermentation of the material, ensure the activity of microorganisms, thereby ensuring the efficiency of the entire fermentation process, and thus improving the alcohol yield and quality.

[0032] In one embodiment, the stirring mechanism 7 includes a motor 701 extending through the top of the fermentation cover 2. A hollow column 702 is disposed on the outer side of the motor 701. A rotating cylinder 703 is connected to the bottom end of the motor 701. The top of the rotating cylinder 703 is connected to the hollow column 702 via a bearing 704. The inner wall of the hollow column 702 is connected to the motor 701 via a bearing 705. A fixing plate 706, connected to the fermentation cover 2, is symmetrically disposed at the top of the hollow column 702. A plurality of sliding grooves 707 are formed on the outer side of the hollow column 702, and the interior of each sliding groove 707 is provided with... A plurality of sliding columns 708 are provided. A connecting rod 709 is provided at the end of each sliding column 708 away from the chute 707. A connecting column 710, penetrating the rotating cylinder 703, is provided at the bottom of the side of the connecting rod 709 away from the chute 707. The connecting column 710 and the rotating cylinder 703 are connected by a bearing 711. A mixing component 712 is provided at one end of the connecting column 710 for agitating the material. The chute 707 includes a plurality of arc-shaped grooves 7071 formed on the outside of the hollow column 702. An arc-shaped groove 7072 is provided at the bottom of one side of each arc-shaped groove 7071. One end of each arc-shaped groove 7071 connects to the bottom of the arc-shaped groove 7072. One end of component 2 is connected via an inclined slot 7073; the mixing component 712 includes a rotating blade 7121 disposed at one end of the connecting column 710, the top end of the rotating blade 7121 is provided with a plurality of arc-shaped rods 7122, the bottom end of the rotating blade 7121 is provided with a plurality of arc-shaped rods 7123, and both sides of the rotating blade 7121 are provided with a plurality of conical blocks 7124; the plurality of arc-shaped rods 7122 are staggered and rectangularly distributed at the top end of the rotating blade 7121; the plurality of arc-shaped rods 7123 are staggered and rectangularly distributed at the bottom end of the rotating blade 7121; and the arc-shaped rods 7122 and the arc-shaped rods 7124 are... The bending direction of rod 7123 is opposite; under the action of several arc-shaped rods 7122 and several arc-shaped rods 7123, the material in different layers can be cut, dispersed and mixed, increasing the relative movement between materials, further promoting the contact between materials and fermentation liquid, and improving fermentation efficiency. At the same time, under the action of the conical structure of several conical blocks 7124, the adhesion between materials is effectively broken, reducing the possibility of material accumulation, while generating more turbulence, which helps the mixing between materials and fermentation liquid, and breaks the bubbles that may be formed during the stirring process, preventing bubbles from affecting the uniform distribution of materials and the fermentation process.

[0033] The working principle of the stirring mechanism 7 is as follows: by starting the motor 701, the rotating cylinder 703 is driven to rotate, and under the limiting action of the slide groove 707, the sliding column 708 moves along the path of the slide groove 707, so that the mixing component 712 can revolve around the hollow column 702 and rotate on its own axis at the same time. This allows several arc-shaped rods 7122 and several arc-shaped rods 7123 to turn over the material, cut, disperse and mix the material in different layers, increase the relative movement between the materials, further promote the contact between the materials and the fermentation liquid, and improve the fermentation efficiency. At the same time, under the action of the conical structure of several conical blocks 7124, the adhesion between the materials is effectively broken, reducing the possibility of material accumulation. At the same time, more turbulence is generated, which helps the mixing between the materials and the fermentation liquid, and breaks the air bubbles that may be formed during the stirring process, preventing the air bubbles from affecting the uniform distribution of the materials and the fermentation process.

[0034] In one embodiment, the discharge assembly 8 includes a discharge pipe 801 located at the bottom of the fermentation tank 1. A water outlet valve 802 is installed inside the discharge pipe 801. One end of the discharge pipe 801 is connected to a filter pipe 803, and the filter pipe 803 has several intercepting columns 804 installed inside. The discharge pipe 801 and the filter pipe 803 are connected by threads. The intercepting columns 804 are evenly arranged and circumferentially distributed inside the filter pipe 803, and the intercepting columns 804 are arc-shaped columns. The intercepting columns 804 can reduce the probability of clogging of the filter pipe 803 by intercepting the fermentation residue in advance, and improve the quality of the wine flowing out of the discharge pipe 801 under the further filtration of the filter pipe 803. If the filter pipe 803 is clogged, the filter pipe 803 can be removed from the discharge pipe 801 by rotating the filter pipe 803, which is convenient for the operator to clean the filter pipe 803 and ensure the smoothness of subsequent discharge.

[0035] In addition, it should be noted that a sealing element is provided between the fermentation tank 1 and the fermentation cover 2, and the fermentation tank 1 and the fermentation cover 2 are connected by several bolts. This sealing element and connection method are existing technologies, and will not be elaborated on here.

[0036] In addition, it should be noted that the fermenter 1 is equipped with a heating element. In specific applications, a heating belt can be used. This heating belt consists of a resistance wire, an insulation layer, an outer sheath, and a temperature control device. This heating belt is existing technology and will not be elaborated on here.

[0037] In addition, it should be noted that the exhaust pipe 5 is equipped with a one-way valve, which can only discharge the gas inside the fermenter 1. This one-way valve is existing technology and will not be elaborated on here.

[0038] In addition, it should be noted that the pressure sensor 4 and the exhaust pipe 5 are electrically connected. The pressure sensor 4 monitors the internal pressure of the fermenter 1 in real time. When the internal pressure of the fermenter 1 is detected to be too high, the one-way valve inside the exhaust pipe 5 is activated to discharge the gas inside the fermenter 1 and reduce the internal pressure of the fermenter 1.

[0039] In addition, it should be noted that the temperature sensor 6 is electrically connected to the heating element inside the fermentation tank 1. The temperature sensor 6 monitors the temperature inside the fermentation tank 1 in real time. When the temperature inside the fermentation tank 1 is detected to exceed the temperature required for fermentation, the heating element stops heating. When the temperature inside the fermentation tank 1 is detected to be lower than the temperature required for fermentation, the heating element is activated to heat until the temperature sensor 6 detects that the temperature inside the fermentation tank 1 has reached the temperature required for fermentation.

[0040] In addition, it should be noted that the above-mentioned water outlet valve 802 can use a structure similar to a faucet in specific applications. This faucet is existing technology and will not be elaborated on here.

[0041] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0042] In practical applications, the fermentation lid 2 is opened, and the starch raw material is added to the fermentation tank 1. Then, water, mold, fermentation microorganisms, nitrogen source, phosphorus source, and acid-base regulator are added into the fermentation tank 1 through the feed pipe 3. The fermentation tank 1 is then heated by the heating element. The motor 701 is started, which drives the rotating cylinder 703 to rotate. Under the limiting action of the slide groove 707, the sliding column 708 moves along the path of the slide groove 707, so that the mixing component 712 can revolve around the hollow column 702 and rotate on its own axis at the same time, thereby ensuring that the starch raw material and the fermentation liquid are fully mixed and in contact (the working principle of the stirring mechanism 7 is as described above). During the fermentation process, the pressure sensor 4 and the temperature sensor 6 are used for monitoring. The pressure and temperature inside the fermentation cap 2 are measured and adjusted to control the fermentation temperature between 20 and 30 degrees Celsius until fermentation is complete. By opening the water outlet valve 802, and with the pre-interception of fermentation residue by several intercepting columns 804, the probability of clogging of the filter tube 803 is reduced. The further filtration by the filter tube 803 improves the quality of the wine flowing out of the discharge pipe 801. If the filter tube 803 becomes clogged, the water outlet valve 802 is closed, and then the filter tube 803 is rotated to remove it from the discharge pipe 801 for easy cleaning by the operator. After cleaning, the filter tube 803 is rotated in the opposite direction and installed on the discharge pipe 801 to continue filtration and discharge.

[0043] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the fermentation tank 1, fermentation cover 2, feed pipe 3, pressure sensor 4, exhaust pipe 5, temperature sensor 6, stirring mechanism 7, and discharge component 8, not only can the fermentation of starch raw materials be achieved, but also material accumulation is avoided, ensuring thorough mixing and contact between the material and the fermentation liquid, preventing incomplete local fermentation, guaranteeing microbial activity, and thus ensuring the efficiency of the entire fermentation process, thereby improving alcohol yield and quality. The stirring mechanism 7, through the agitation action of several arc-shaped rods 7122 and 7123, cuts, disperses, and mixes materials in different layers, increasing the relative movement between materials, further promoting contact between the material and the fermentation liquid, and improving fermentation efficiency. The process effectively breaks down the adhesion between materials and reduces the possibility of material accumulation under the action of the conical structure of several conical blocks 7124. At the same time, it generates more turbulence, which helps to mix the materials with the fermentation liquid and breaks up the bubbles that may be formed during the stirring process, preventing the bubbles from affecting the uniform distribution of materials and the fermentation process. Through the discharge component 8, the probability of clogging of the filter tube 803 can be reduced by the interception of fermentation residue by several interception columns 804. Under the further filtration of the filter tube 803, the quality of the wine flowing out of the discharge pipe 801 is improved. If the filter tube 803 is clogged, it can be removed from the discharge pipe 801 by rotating the filter tube 803, which is convenient for the operator to clean the filter tube 803 and ensure the smoothness of subsequent discharge.
