[0014] The present invention provides a mixing and stirring mechanism for beer production, which has the following beneficial effects: (1) The beer production mixing and stirring mechanism drives the addition cylinder to rotate by rotating the fixed frame. Under the action of the fixed frame, the addition cylinder rotates with the rotating shaft as the center to evenly stir the additives in the addition cylinder. The full mixing of yeast and malt juice can shorten the fermentation start-up time, reduce the risk of contamination by foreign bacteria, improve the consistency of fermentation degree, and improve the flavor stability of the finished beer.

[0016] (3) The beer production mixing and stirring mechanism drives the outer plate to rotate through the rotation of the inner ring, and at the same time, the stirring plate drives the inner plate to rotate to stir and mix the beer inside the mixing drum, thereby breaking the surface tension, promoting the rapid dispersion of additives, improving the uniformity of the beer, improving the effect and efficiency of stirring and mixing, and avoiding the taste of the beer being affected by uneven stirring. The wheel realizes orbital revolution and self-rotation at the same time. At the same time, the rotation of the wheel drives the cleaning roller to rotate, and the rotation of the cleaning roller drives the bristles to rotate. The rotation of the bristles scrapes off the sticky materials attached to the inner wall of the mixing drum and draws them into the mainstream field, thereby avoiding the carbonization or deterioration of the materials and reducing the risk of microbial growth. If the sticky and sticky materials are not cleaned up, it will affect the flavor and quality control of the next mixed beer.

[0017] (4) The beer production mixing and stirring mechanism drives the second rotating rod to rotate by the rotation of the second rotating wheel, and the rotation of the second rotating rod drives the defoaming ring to rotate. The bubbles generated during the beer stirring process are eliminated by the mechanical shear force generated by the rotation of the defoaming ring.

[0018] (5) The mixing and stirring mechanism for beer production contacts and squeezes the knocking plate by rotating the eccentric wheel No. 2 to move it in the direction close to the inscribed ring until it contacts and collides with the surface of the inscribed ring to generate vibration. At this time, the inscribed ring rotates and transmits the rotation to the rotating shaft No. 2 to shake off the viscous material attached to its surface, thereby achieving the self-cleaning effect of the core components, reducing the frequency of manual disassembly and cleaning, and reducing labor intensity. At the same time, the vibration wave is transmitted to the liquid surface, destroying the foam stability, accelerating the breakage of large bubbles into small bubbles, and then being eliminated by secondary shearing of the defoaming ring, thereby improving the foam control of the beer.

Subsequently, the beer after mixing and stirring is discharged through the discharge pipe 3.

[0026] Please refer to Figures 1-7 , on the basis of the above - mentioned embodiment, in another embodiment of the present invention, a stirring device for stirring the beer inside the stirring cylinder 2 is arranged on the circumferential surface of the second rotating shaft 52. The stirring device includes a first stirring plate 61. The first stirring plate 61 is fixedly installed on the circumferential surface of the second rotating shaft 52. An inner - cut ring 62 is fixedly installed on the circumferential surface of the second rotating shaft 52. An outer - cut plate 63 is fixedly installed on the circumferential surface of the inner - cut ring 62. An inner - cut plate 64 is fixedly installed on the surface of the first stirring plate 61. A first rotating rod 65 rotates through the surface of the first stirring plate 61. A first runner 66 is fixedly installed on the circumferential surface of the first rotating rod 65. A cleaning roller 67 is fixedly installed on the circumferential surface of the first rotating rod 65. The first runner 66 rotates to drive the cleaning roller 67 to rotate. The cleaning roller 67 rotates to drive the bristles to rotate.

[0027] The circumferential surface of the cleaning roller 67 is provided with bristles for cleaning the inner wall of the mixing drum 2. The angle of the outer cutting plate 63 is set as an inclined angle. The inner cutting ring 62 rotates to drive the outer cutting plate 63 to rotate. At the same time, the first stirring plate 61 rotates to drive the inner cutting plate 64 to rotate to stir and mix the beer inside the mixing drum 2.

[0028] The angle of the inner cutting plate 64 is set as an inclined angle. The first runner 66 contacts the inner wall of the mixing drum 2. The first rotating rod 65 rotates to drive the first runner 66 to rotate. Since the first runner 66 contacts the inner wall of the mixing drum 2, the first runner 66 rotates under the action of the mixing drum 2.

[0029] The circumferential surface of the first stirring plate 61 is provided with a defoaming device for eliminating bubbles by mechanical shear force. The defoaming device includes a second stirring plate 71. The second stirring plate 71 is fixedly installed on the circumferential surface of the first stirring plate 61. A second rotating rod 72 rotates through the surface of the first stirring plate 61. A second runner 73 is fixedly installed on the circumferential surface of the second rotating rod 72. A defoaming ring 74 is fixedly installed on the circumferential surface of the second rotating rod 72. A third rotating shaft 75 is rotatably installed on the surface of the second stirring plate 71. A contact wheel 76 is fixedly installed on the circumferential surface of the third rotating shaft 75. An eccentric wheel 77 is fixedly installed on the circumferential surface of the third rotating shaft 75. A striking plate 78 is slidably installed on the surface of the second stirring plate 71. The eccentric wheel 77 rotates to contact and squeeze the striking plate 78 to move towards the inner cutting ring 62 until it contacts and collides with the surface of the inner cutting ring 62 to generate vibration.

[0030] One end of the striking plate 78 close to the inner cutting ring 62 is provided with a striking hammer for striking the inner cutting ring 62 to generate vibration.

[0031] When the present embodiment is working, the second rotating shaft 52 rotates under the action of the motor 4, driving the stirring plate 1 61 to rotate, stirring the beer inside the stirring drum 2, and at the same time, the stirring plate 1 61 rotates to drive the inner ring 62 to rotate, and the inner ring 62 rotates to drive the outer plate 63 to rotate, and at the same time, the stirring plate 1 61 rotates to drive the inner plate 64 to rotate to stir and mix the beer inside the stirring drum 2, breaking the surface tension, promoting the rapid dispersion of additives, improving the uniformity of the beer, improving the effect and efficiency of stirring and mixing, and avoiding the taste of the beer being affected by uneven stirring. The stirring plate 1 61 rotates to drive the rotating rod 1 65 to rotate. The rotating shaft 52 rotates as the center of the circle, and the rotating rod 65 rotates to drive the rotating wheel 66 to rotate. Because the rotating wheel 66 contacts the inner wall of the mixing drum 2, the rotating wheel 66 rotates under the action of the mixing drum 2. At this time, the rotating wheel 66 realizes orbital revolution and self-rotation at the same time. At the same time, the rotation of the rotating wheel 66 drives the cleaning roller 67 to rotate, and the rotation of the cleaning roller 67 drives the bristles to rotate. The rotation of the bristles scrapes off the viscous material attached to the inner wall of the mixing drum 2 and draws it into the mainstream field, so as to avoid the carbonization or deterioration of the material and reduce the risk of microbial growth. If the sticky viscous material is not cleaned up, it will affect the flavor and quality control of the next mixed beer.

[0032] When the stirring plate 1 61 rotates under the action of the rotating shaft 2 52, it drives the stirring plate 2 71 to rotate, the stirring plate 2 71 drives the rotating rod 2 72 to rotate, and the rotating rod 2 72 drives the rotating wheel 2 73 to rotate with the rotating shaft 2 52 as the center. Because the rotating wheel 2 73 is in contact with the inner wall of the mixing drum 2, the rotating wheel 2 73 rotates under the action of the inner wall of the mixing drum 2. At the same time, the rotation of the rotating wheel 2 73 drives the rotating rod 2 72 to rotate, and the rotation of the rotating rod 2 72 drives the defoaming ring 74 to rotate. The rotation of the defoaming ring 74 eliminates the bubbles generated in the process of stirring the beer through the mechanical shear force generated by the rotation of the defoaming ring 74. The bubble film is torn and cut by the serrated edge and quickly ruptures, thereby preventing the accumulation of foam from affecting the liquid level monitoring or causing overflow. The foam in the beer will affect the overall flavor and yield of the beer, which is helpful In order to improve the consistency of beer, at the same time, because the rotating rod 2 72 is in contact with the contact wheel 76, the rotating rod 2 72 rotates to drive the contact wheel 76 to rotate, and at the same time, the rotation of the contact wheel 76 drives the rotating shaft 3 75 to rotate, and the rotation of the rotating shaft 3 75 drives the eccentric wheel 2 77 to rotate, and the eccentric wheel 2 77 rotates to contact and squeeze the knocking plate 78 to move in the direction close to the inner ring 62 until it contacts and collides with the surface of the inner ring 62 to generate vibration. At this time, the inner ring 62 rotates to transmit the rotation to the rotating shaft 2 52 to shake off the viscous material attached to its surface, thereby achieving the self-cleaning effect of the core components, reducing the frequency of manual disassembly and cleaning, and reducing labor intensity. At the same time, the vibration wave is transmitted to the liquid surface, destroying the foam stability, accelerating the rupture of large bubbles into small bubbles, and then being eliminated by secondary shearing of the defoaming ring 74, thereby improving the foam control of the beer.
