Technical Field

[0001] The invention relates to the technical field of beer production and fermentation, in particular to a fermentation tank for beer production and processing. Background Art

[0002] The beer fermentation process is the normal life activity of brewer's yeast under specific conditions, which utilizes the fermentable substances in the wort. The metabolic products are the desired products. In the production and processing of beer, fermentation tanks are often needed to assist in production.

[0003] Patent application with application number CN202321232557.9 discloses a fermentation tank for beer production and processing, including a fermentation tank, a sealing cover is movably installed on the top of the fermentation tank, support legs are fixedly installed on all four sides of the bottom end of the fermentation tank, and brackets are welded on the inner side of the support legs. A sealing unit is arranged on the top of the fermentation tank, and a stirring unit and a cleaning unit are arranged inside the fermentation tank, and the stirring unit is arranged inside the fermentation tank.

Because the agitator wheel generates a certain mechanical shear force when rotating at high speed, the cell wall of the yeast cells may be destroyed, resulting in reduced yeast activity, thereby affecting the fermentation efficiency, and increasing the content of higher alcohols and esters in the beer, affecting the flavor stability of the beer.

[0016] Compared with the prior art, the present invention provides a fermentation tank for beer production and processing, which has the following beneficial effects:

[0017] 1. The present invention provides a fermentation tank for beer production and processing. During the beer fermentation process, the motor drives the cleaning and stirring assembly to operate with the help of the first connecting frame, and the beer fermentation liquid is stirred by the stirring rod.

[0019] 3. The present invention sets baffles and arc rods to reduce the rotation speed of the bottom of the fermentation liquid, so as to make the surface of the fermentation liquid more stable, thereby reducing the generation of foam. This can avoid the risk of increased contamination due to increased foam, which is beneficial to improving the quality of the finished beer.

In this process, the cleaning plate and the cleaning roller are used to clean the inner wall of the fermentation bin to prevent part of the beer fermentation liquid yeast from sticking to the inner wall of the fermentation bin. At the same time, the stirring rod is used to stir the beer fermentation liquid. The beer fermentation liquid enters the stirring rod through the second inclined plate, and then the beer fermentation liquid in the stirring rod is discharged through the connecting pipe. This can reduce the damage to the cell wall of the yeast cells, thereby improving the yeast activity and enhancing the stability of the beer flavor. BRIEF DESCRIPTION OF THE DRAWINGS

The first sliding block 201 runs through the first connecting block 202 and is fixedly connected to an exhaust pipe 205. It also includes:

[0034] The regulating mechanism 3 comprises a motor 301 fixedly connected to the bottom outer wall of the fermentation bin 101, the output end of the motor 301 passes through the fermentation bin 101 and is fixedly connected to a first connecting frame 302, a second through hole 303 is provided on the outer surface of the first connecting frame 302, a second fixed shaft 304 is fixedly connected to the inner wall of the second through hole 303, a connecting shaft 305 is fixedly connected to the outer wall of the first connecting frame 302 away from the motor 301, a second sliding block 306 is slidably connected to the outer surface of the connecting shaft 305, and a cleaning and stirring assembly 314 is arranged on the top of the first connecting frame 302. During the beer fermentation process, the motor 301 drives the cleaning and stirring assembly 314 to operate with the help of the first connecting frame 302, and the beer fermentation liquid is stirred by the stirring rod 3148. The beer fermentation liquid flows into the stirring rod 3148 through the second inclined plate 3149, and then the beer fermentation liquid in the stirring rod 3148 is discharged through the connecting pipe 31410, thereby reducing the damage to the cell wall of the yeast cells, thereby improving the yeast activity and enhancing the stability of the beer flavor.

[0035] The top outer wall of the first connecting block 202 is fixedly connected to the first fixed shaft 204, the outer surface of the first fixed shaft 204 is slidably connected to the first sliding frame 206, the bottom outer wall of the first sliding frame 206 is fixedly connected to the first spring 207, the first spring 207 is used for resetting the first sliding frame 206, one end of the first spring 207 away from the first sliding frame 206 is fixedly connected to the first connecting block 202, and the inner wall of the first sliding frame 206 is slidably connected to the outer wall of the exhaust pipe 205.

[0036] The bottom outer wall of the first sliding block 201 is fixedly connected to a fixed block 208, and the inner wall of the fixed block 208 is fixedly connected to a baffle 209.
