Description

Technical Field

[0001] The present invention relates to the technical field of fermentation, in particular to fermentation equipment for craft wheat beer. Background Art

[0002] The craft beer industry has experienced rapid growth in recent years, with consumers increasingly demanding higher quality and flavor. Wheat beer, a key component of the craft beer category, places higher demands on fermentation processes and equipment due to its unique estery, fruity aroma, and mellow taste. Traditional fermentation equipment is gradually experiencing the following problems in practical applications:

[0003] Early fermentation equipment often employed single- or double-layer agitation structures, making it difficult to cover the entire height of the tank. Materials easily settled at the bottom, resulting in insufficient contact between yeast and wort and inconsistent fermentation rates. Furthermore, single-directional agitation easily formed vortices, creating localized dead zones and affecting beer flavor consistency. Traditional agitators also had blind spots in the curved bottom of the tank, leading to incomplete fermentation. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a fermentation device for craft wheat beer.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a fermentation device for craft wheat beer, comprising a tank body, a bottom fixedly mounted on the upper portion of the tank body, an air intake mechanism mounted on the top portion of the tank body for supplying air to the interior of the tank body, and the air intake mechanism processes external air and then delivers it to the interior of the tank body;

[0008] An exhaust hole is provided on the outside of the tank body, and an exhaust mechanism is fixedly installed on the exhaust hole. The exhaust mechanism is used to discharge the waste gas in the tank body.

[0009] Preferably, the stirring device includes a rotating shaft, which is arranged at the center of the tank body, and the bottom of the rotating shaft passes through the tank body and is connected to an external motor, and the motor drives the rotating shaft to rotate in the tank body;

As the rotating shaft rotates, the first stirrer and the second stirrer rotate after being affected by the raw materials and auxiliary materials. The stirring efficiency is improved through multiple rotational stirring methods.

[0014] Preferably, a first rotating block is fixedly installed at the upper position of the rotating shaft, a stirring plate is fixedly installed on the outside of the first rotating block, an elastic rope is fixedly installed on the stirring plate, the elastic rope is connected to the sphere, and the elastic rope is used to limit the movement of the sphere.

[0016] Preferably, the stirring blades on the first stirrer and the second stirrer are inclined in opposite directions. When the first stirrer and the second stirrer rotate, the first stirrer and the second stirrer rotate in opposite directions due to the restriction of the inclination direction of the stirring blades of the two stirrers.

[0017] Preferably, the air intake mechanism includes a shell, the shell is engaged with the top of the tank body, and two connecting pipes connected to the interior of the shell are fixedly installed on the upper surface of the shell, and an electrolysis rod is placed in each connecting pipe.

[0023] A water-absorbing sponge is fixedly installed on the other end of the exhaust pipe, and a connecting rod is fixedly installed on the end of the exhaust pipe where the water-absorbing sponge is installed. A collecting box is fixedly installed on the connecting rod for collecting waste water.

[0024] Compared with the prior art, the present invention provides a fermentation device for craft wheat beer, which has the following beneficial effects:

[0025] 1. This craft wheat beer fermentation equipment achieves full-dimensional mixing of materials through a multi-layer stirring system, uses an air intake mechanism to accurately control the gas environment, and uses an exhaust mechanism to ensure pressure safety. The overall design improves the uniformity, stability and safety of craft wheat beer fermentation.

[0026] 2. The fermentation equipment for craft wheat beer can achieve three-dimensional mixing of materials, improve fermentation uniformity, ensure a stable fermentation environment, and avoid abnormal pressure affecting fermentation quality.

[0027] 3. The bottom stirring blade of this craft wheat beer fermentation equipment is designed to fit the bottom of the tank in an arc shape to avoid material sedimentation and improve stirring efficiency. The inclined blades force material convection and accelerate the dissolution and reaction of raw materials and auxiliary materials.

[0028] 4. The fermentation equipment for craft wheat beer uses a multi-directional stirring mechanism that realizes large-scale mixing through revolution, generates local shear force through rotation, breaks up material agglomerates, improves mixing accuracy, and utilizes material resistance to drive the agitator to rotate, reducing additional power consumption.

[0029] 5. The fermentation equipment for craft wheat beer has a stirring plate and a multi-directional stirring mechanism connected by elastic ropes to enhance the interactive mixing of the upper and lower layers of materials. The elastic connection can buffer the impact force during the stirring process and improve the durability of the equipment.

[0030] 6. In the fermentation equipment for craft wheat beer, the spring expansion and contraction can buffer the fluctuation of material resistance, thereby preventing the agitator from being overloaded or stuck. The elastic displacement of the rotating rod 35 expands the stirring range and reduces the retention of material in the middle of the tank.

[0031] 7. The fermentation equipment for craft wheat beer uses a stirrer that rotates in the opposite direction to generate strong convection, breaking up large molecular agglomerates and promoting full contact between raw materials and yeast and other ingredients. The two-way stirring reduces eddy currents and makes the material more evenly distributed on the cross section of the tank.

[0032] 8. The fermentation equipment for craft wheat beer uses a water layer to filter impurities in the air. The gas generated by electrolysis can adjust the oxygen content in the tank and optimize yeast activity. According to the needs of the fermentation stage, the gas composition is controlled by the electrolysis intensity. For example, oxygen supply in the early stage promotes yeast reproduction, and oxygen supply is reduced in the later stage to control the fermentation speed.

[0033] 9. The fermentation equipment for craft wheat beer uses a double purification method of filter sponge and water layer to prevent bacteria or impurities from contaminating the fermentation materials. The humidified gas maintains the appropriate humidity in the tank and promotes yeast metabolic activity.

[0034] 10. The fermentation equipment for craft wheat beer has a one-way valve to prevent the backflow of external air, ensuring the fermentation environment is sealed and avoiding the risk of tank explosion. The absorbent sponge filters liquid impurities in the exhaust gas, and the collection box facilitates centralized treatment of wastewater, meeting environmental protection requirements.

DETAILED DESCRIPTION

[0041] 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.

[0042] Example 1

[0043] See also Figure 1-Figure 2 A fermentation device for craft wheat beer includes a tank body 11, a bottom 10 is fixedly mounted on the top of the tank body 11, and is characterized in that an air intake mechanism 14 for supplying air to the interior of the tank body 11 is mounted on the top of the tank body 11, and the air intake mechanism 14 processes the external air and then delivers it to the interior of the tank body 11;

[0044] The raw materials and auxiliary materials of the craft wheat beer are placed inside the tank body 11, and a stirring device for stirring the raw materials and auxiliary materials is provided inside the tank body 11;

[0045] The stirring device is divided into three layers, from top to bottom, which are the stirring plate 18, the multi-directional stirring mechanism 20 and the bottom stirring sheet 21, stirring and mixing the raw materials and auxiliary materials from multiple angles and levels;

[0046] An exhaust hole 12 is formed on the outside of the tank body 11 , and an exhaust mechanism 13 is fixedly mounted on the exhaust hole 12 . The exhaust mechanism 13 is used to exhaust the exhaust gas in the tank body 11 .

[0047] After being processed by the air intake mechanism 14, external air is introduced into the tank body 11 via the air delivery pipe 24, providing the necessary air for fermentation. A three-layer stirring mechanism stirs the raw and auxiliary materials at different levels. The top stirring plate 18 initially mixes the materials. The middle multi-directional stirring mechanism 20 enhances the mixing effect by rotating at multiple angles. The bottom stirring blades 21 conform to the curved tank bottom, pushing the materials up and down. Exhaust gases generated by fermentation are discharged through the exhaust hole 12 and controlled by the one-way valve 30 of the exhaust mechanism 13.

[0048] Example 2

[0049] See also Figure 2 The stirring device includes a rotating shaft 15, which is arranged at the center of the tank body 11. The bottom of the rotating shaft 15 passes through the tank body 11 and is connected to an external motor. The motor drives the rotating shaft 15 to rotate in the tank body 11;

[0050] A bottom stirring blade 21 is fixedly mounted on the bottom of the rotating shaft 15. The bottom stirring blade 21 is driven by the rotating shaft 15 to rotate at the bottom of the tank body 11. The bottom of the tank body 11 is designed to be arc-shaped, and the shape of the bottom stirring blade 21 is adapted to the bottom of the tank body 11.

[0051] The bottom stirring blade 21 is designed to be inclined. The rotation of the bottom stirring blade 21 drives the raw material and the auxiliary material to rotate and stir, and the raw material and the auxiliary material are stirred and mixed in the upper and lower layers.

[0052] The external motor drives the rotating shaft 15 to rotate, driving the bottom stirring blade 21 to rotate along the bottom of the tank. When the inclined bottom stirring blade 21 rotates, it not only pushes the material to move in a circle along the bottom of the tank, but also lifts the bottom material upward through the tilt angle to achieve mixing of the upper and lower layers.

[0053] Example 3

[0054] See also Figure 2 and Figure 5 A second rotating block 17 is fixedly mounted in the middle of the rotating shaft 15, and four multi-directional stirring mechanisms 20 are fixedly mounted on the second rotating block 17, and the four multi-directional stirring mechanisms 20 rotate as the rotating shaft 15 rotates;

[0055] The multi-directional stirring mechanism 20 includes a sphere 34, a rotating shaft 15, a first stirrer 36 and a second stirrer 37. The first stirrer 36 and the second stirrer 37 are provided with stirring blades 38. As the rotating shaft 15 rotates, the first stirrer 36 and the second stirrer 37 are affected by the raw materials and auxiliary materials and rotate. The stirring efficiency is improved through multiple rotational stirring methods.

[0056] The rotating shaft 15 drives the second rotating block 17 to rotate, and the multi-directional stirring mechanism 20 revolves along with the rotating shaft. The stirring blades 38 on the first stirrer 36 and the second stirrer 37 rotate themselves due to the resistance of the material, forming a compound motion of "revolution + rotation".

[0057] Example 4

[0058] See also Figure 2 A first rotating block 16 is fixedly installed at the upper position of the rotating shaft 15, and a stirring plate 18 is fixedly installed on the outside of the first rotating block 16. An elastic rope 19 is fixedly installed on the stirring plate 18, and the elastic rope 19 is connected to the ball 34. The elastic rope 19 is used to limit the movement of the ball 34.

[0059] The stirring plate 18 rotates with the rotating shaft 15 to stir the upper material. The elastic rope 19 limits the movement range of the ball 34, so that the multi-directional stirring mechanism 20 remains stable during revolution, while allowing a certain elastic displacement to avoid hard collision and damage to the equipment.

[0060] Example 5

[0061] See also Figure 2 and Figure 5The multi-directional stirring mechanism 20 includes a rotating rod 35, on which a first agitator 36 and a second agitator 37 are rotatably mounted. A sphere 34 is fixedly mounted on one end of the rotating rod 35, and a spring 39 is fixedly mounted on the other end of the rotating rod 35. The spring 39 extends into the interior of the rotating rod 35 and is fixedly connected to the second rotating block 17. The spring 39 provides an active telescopic amount for the movement and displacement of the rotating rod 35.

[0062] One end of the rotating rod 35 is connected to the elastic rope 19 through the ball 34, and the other end is fixed to the second rotating block 17 through the spring 39. When the material resistance changes, the spring 39 expands and contracts to adjust the position of the rotating rod 35, so that the agitator can adapt to different material viscosities and maintain the stirring effect.

[0063] Example 6

[0064] See also Figure 5 The stirring blades 38 on the first stirrer 36 and the second stirrer 37 are tilted in opposite directions. When the first stirrer 36 and the second stirrer 37 rotate, the first stirrer 36 and the second stirrer 37 rotate in opposite directions due to the restriction of the tilt direction of the stirring blades 38 of the two.

[0065] Since the stirring blades 38 are tilted in opposite directions, when the material flows through, the two are subjected to opposite directions of fluid force, causing the first agitator 36 and the second agitator 37 to rotate in opposite directions. The reverse rotation generates shear force, which enhances the dispersion and mixing effect on the material.

[0066] Example 7

[0067] See also Figure 1 and Figure 3 The air intake mechanism 14 includes a shell 22, which is engaged with the top of the tank body 11. Two connecting pipes 23 communicating with the interior of the shell 22 are fixedly mounted on the upper surface of the shell 22. An electrolysis rod 25 is placed in each connecting pipe 23. The two electrolysis rods 25 are connected to an external power supply and are used to electrolyze the water in the shell 22.

[0068] A water inlet is provided at the center of the housing 22, and a sealing cover 26 is fixedly mounted on the water inlet;

[0069] An air inlet pipe 40 is fixedly mounted on the upper surface of the housing 22 , and an air delivery pipe 24 is fixedly mounted on the side surface of the housing 22 .

[0070] After the sealing cover 26 is opened, water is injected into the shell 22. When the electrolysis rod 25 is energized, water is electrolyzed to produce hydrogen and oxygen. External air enters the shell 22 through the air inlet pipe 40, is filtered through the water layer, and is mixed with the gas produced by electrolysis and then passed into the tank body 11 through the gas supply pipe 24.

[0071] Example 8

[0072] See also Figure 3 A grid plate 27 is fixedly installed in the middle position of the interior of the housing 22, a filter sponge 28 is placed above the grid plate 27, and water is poured under the grid plate 27. The position of the air pipe 24 is adapted to the position of the filter sponge 28;

[0073] The air inlet pipe 40 extends through the filter sponge 28 into the water.

[0074] External air first passes through the filter sponge 28 through the air inlet pipe 40 to remove dust and other particulate impurities, and then is further filtered through the water layer and humidified to prevent dry air from affecting the fermentation environment. The cleaned gas enters the tank body 11 through the air supply pipe 24.

[0075] Embodiment 9

[0076] See also Figure 1 and Figure 4 The exhaust mechanism 13 includes an exhaust pipe 29, which is bent. A one-way valve 30 is fixedly installed at one end of the exhaust pipe 29 close to the exhaust hole 12. The one-way valve 30 sets a pressure value. When the internal pressure of the tank body 11 exceeds the pressure value set by the one-way valve 30, the one-way valve 30 discharges the exhaust gas in the tank body 11, and the exhaust gas is transported through the exhaust pipe 29.

[0077] A water-absorbing sponge 31 is fixedly mounted on the other end of the exhaust pipe 29 , and a connecting rod 32 is fixedly mounted on one end of the exhaust pipe 29 where the water-absorbing sponge 31 is mounted. A collecting box 33 is fixedly mounted on the connecting rod 32 for collecting wastewater.

[0078] When the pressure in the tank 11 exceeds the set value of the one-way valve 30, the exhaust gas pushes open the one-way valve and is discharged through the exhaust pipe 29. The bent pipe extends the exhaust gas path, and the absorbent sponge 31 absorbs moisture in the exhaust gas and the waste water drips into the collection box 33.

[0079] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
