Description

Technical Field

[0001] The utility model relates to the technical field of beer fermentation, in particular to a beer fermentation sugar measuring and can sealing device. Background Art

[0002] The beer fermentation process is the normal life activity of beer yeast under certain conditions, using fermentable substances in wort, and its metabolic product is the desired product - beer. Due to different types of yeast, fermentation conditions and product requirements, flavors, and fermentation methods are different, and beer needs to be stirred during fermentation, but the existing fermentation equipment does not stir evenly enough.

[0003] For example, Chinese patent publication No. CN220034430U discloses a fermentation tank for beer brewing. When in use, the output end of the second motor drives the support rod and the stirring plate to rotate, so that the stirring plate mixes and stirs the beer inside the fermentation tank. At the same time, the output end of the first motor drives the screw rod to rotate, so that the screw rod drives the adjustment block to slide in the inner cavity of the support cover. The adjustment block drives the bottom end of the support rod and the stirring plate to move vertically inside the fermentation tank through the lifting plate and the second motor, so that the stirring plate stirs the beer evenly. After the beer is fermented, the beer can be discharged through the drain pipe by opening the valve seat, such as the inside of the fermentation tank. When cleaning the wall, the water pump draws out the cleaning water from the inner cavity of the water tank through the No. 1 conduit, and discharges it into the annular water pipe through the No. 2 conduit, and at the same time sprays it out through the nozzle to clean the inner wall of the fermentation tank. At this time, the No. 2 motor drives the support rod to rotate in the same way, and the support rod drives the scraper to rotate through the fixed rod and the annular plate, so that the scraper scrapes off the impurities remaining on the inner wall of the fermentation tank. At the same time, it rotates through the output end of the No. 1 motor and drives the support rod to move vertically in the same way, so that the support rod drives the scraper to move on the inner wall of the fermentation tank through the fixed rod and the annular plate, and scrapes off the impurities remaining on the inner wall of the fermentation tank. The sewage after cleaning is discharged through the drain pipe.

[0004] However, the beer brewing fermentation tank in the above application stirs the beer by raising and lowering the stirring plate, but such operation may cause air pressure leakage in the fermentation tank, thereby affecting the fermentation process. Therefore, there are certain limitations.

[0005] Therefore, we urgently need to provide beer fermentation sugar measuring and can sealing equipment. Utility Model Content

[0006] The utility model aims to provide a beer fermentation sugar measuring and sealing device to solve the problem that the beer brewing fermentation tank proposed in the above background technology stirs the beer by the lifting and lowering cycle of the stirring plate, but such operation will cause the fermentation tank air pressure leakage, thereby affecting the fermentation process.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a beer fermentation sugar measuring can sealing device, comprising a fermentation tank and a support frame, the support frame is fixedly connected to the bottom of the fermentation tank, the top of the fermentation tank is provided with a can sealing device, and the interior of the fermentation tank is provided with a stirring device.

[0009] A further improvement is that the locking assembly includes a U-shaped frame, a connecting frame, a threaded rod, and a nut, the U-shaped frame is fixedly connected to the front end of the movable arm, the connecting frame is fixedly connected to the front of the tank mouth, the threaded rod is installed on the top of the connecting frame, and the nut is threadedly connected to the outside of the threaded rod and is mounted on the U-shaped frame. When the early natural fermentation of the beer is completed and the tank needs to be sealed, the movable arm is rotated to drive the sealed tank cover to be buckled on the top of the tank mouth, and then the nut is turned to rotate downward on the outside of the threaded rod, thereby squeezing the U-shaped frame downward until the sealed tank cover completely closes the tank mouth and the tank is sealed.

[0010] A further improvement is that the stirring device includes a stirring unit and a pressure relief unit.

[0011] The stirring unit includes a stirring motor, a sealed bearing, a stirring shaft, and a stirring plate. The stirring motor is installed at the top center of the fermentation tank, the sealed bearing is installed inside the top center of the fermentation tank, the stirring shaft is connected to the output end of the stirring motor, and is rotatably connected to the inside of the sealed bearing. Three groups of stirring plates are vertically and equidistantly fixed to the outer surface of the stirring shaft. Starting the stirring motor drives the stirring shaft to rotate inside the sealed bearing, thereby driving the stirring plate on the outer surface of the stirring shaft to rotate to stir the beer puree inside the fermentation tank, so that the bad volatile gases and raw beer taste in the beer can be quickly discharged.

[0012] A further improvement is that a spoiler hole is opened through the outer surface of the stirring plate. The opening of the spoiler hole can better cut the beer puree and improve the stirring effect.

When the pressure inside the fermentation tank is too high, the strong air pressure inside it will push the piston upward and compress the strong spring until the piston rises to above the pressure relief hole in the middle of the pressure relief pipe. The air pressure inside the fermentation tank can be discharged from the pressure relief hole. When the pressure inside the fermentation tank returns to normal, the strong spring pushes the piston to reset under the action of its own elasticity, and the fermentation tank is re-sealed. No manual operation is required, and the pressure is adjusted adaptively.

[0015] A further improvement is that a discharge pipe is fixedly connected to the bottom center of the fermentation tank, a sampling tube is installed at the lower front of the fermentation tank, and sealing valves are installed on the outer surfaces of the discharge pipe and the sampling tube.
