Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of malt fermentation, in particular to a special device for malt fermentation. Background Art
[0002] Beer is brewed mainly with barley malt, hops and water as the main raw materials, and is fermented into a low-alcohol wine rich in carbon dioxide.
[0003] During the beer preparation process, the saccharified malt juice needs to be added with yeast and placed in a fermentation tank for static fermentation. A large amount of carbon dioxide gas will be generated during the fermentation process. Therefore, a one-way valve seal will be set at the top of the fermentation tank to ensure that the carbon dioxide gas can be discharged from the fermentation tank while preventing external bacteria from entering the fermentation tank. When no bubbles are generated in the water inside the one-way valve seal, it means that the carbon dioxide has been exhausted. However, during this process, the staff needs to constantly observe whether there are still bubbles generated in the one-way valve seal. Since fermentation is a long process, manual observation cannot accurately ensure that the fermented beer is discharged immediately after the carbon dioxide is exhausted, which results in a delay, resulting in over-fermentation of the beer. Therefore, a special malt fermentation device is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-5 A special device for malt fermentation comprises a fermentation tank 1 and a top cover 2 arranged at the top of the fermentation tank 1, a one-way valve seal 3 for discharging carbon dioxide gas is arranged at the top of the top cover 2, a detection component for detecting whether there is carbon dioxide gas inside the one-way valve seal 3 is arranged at the top of the top cover 2, the detection component comprises a sealing box 4 fixedly connected to the top of the top cover 2 through a vertical plate, a rotating shaft rotatably connected to the inside of the sealing box 4 and a speed sensor 14 fixedly connected to the side wall of the vertical plate, a part of the circumference of the rotating shaft located inside the sealing box 4 is distributed with wind blades 12, an exhaust pipe is arranged at the top of the sealing box 4, a plurality of speed measuring pieces 13 are distributed circumferentially at one end of the rotating shaft located outside the sealing box 4, an installation box 15 is installed on the outer wall of the fermentation tank 1, and a speed sensor 14 for detecting the rotation speed of the speed measuring piece 13 is installed on the inner side of the installation box 15.
[0023] It should be noted that the one-way valve seal 3 is made of a transparent material and contains water. When carbon dioxide gas enters the fermentation tank 1, bubbles will appear in the water in the one-way valve seal 3, and then the carbon dioxide will be discharged into the sealing box 4, thereby driving the wind blade 12 to rotate. The wind blade 12 drives the speed measuring piece 13 to rotate through the rotating shaft. The speed sensor 14 will monitor the rotation speed of the speed measuring piece 13. When the carbon dioxide inside the fermentation tank 1 is exhausted, no more carbon dioxide gas will enter the sealing box 4, so that the speed measuring piece 13 will not rotate. The speed sensor 14 detects that the rotation speed of the speed measuring piece 13 is zero (starting from the time when bubbles are generated inside the one-way valve seal 3 to the time when the carbon dioxide gas flow rate is detected to be zero), and feeds back to the controller 7. The controller 7 controls the solenoid valve 10 to open, so that the beer in the fermentation tank 1 is automatically discharged.
[0024] It is worth noting that a bearing structure is provided at the connection between the rotating shaft and the sealing box 4 .
[0025] The bottom end of the top cover 2 is fixedly connected with a connecting rod 8 , and the bottom end of the connecting rod 8 is fixedly connected with a filter plate 9 for filtering impurities.
[0026] It should be noted that: by lifting the top cover 2 through the handle 5, and then lifting the filter plate 9 through the connecting rod 8, the filtered impurities can be taken out from the inside of the fermentation tank 1, and the impurities on the inner wall of the fermentation tank 1 can be scraped off, thereby realizing the cleaning function of the inner wall of the fermentation tank 1.
[0027] A handle 5 is fixedly connected to the side wall of the top cover 2, a drain pipe 11 is fixedly connected to the bottom end of the fermentation tank 1, a solenoid valve 10 is provided on the drain pipe 11, an electrical box 6 is installed on the side wall of the fermentation tank 1, and a controller 7 is installed inside the electrical box 6.
[0028] It is worth noting that the controller 7 is electrically connected to the solenoid valve 10 and the speed sensor 14 .
[0029] When the utility model is used, the saccharified wort mixed with yeast is placed inside the fermentation tank 1, the top cover 2 is covered, and then the container for holding beer is placed under the discharge pipe 11. The carbon dioxide gas generated during the fermentation process will enter the sealing box 4 through the one-way valve seal 3, and then promote the wind blade 12 to rotate. The wind blade 12 drives the speed measuring piece 13 to rotate through the rotating shaft. The speed measuring sensor 14 will monitor the rotation speed of the speed measuring piece 13. When the carbon dioxide inside the fermentation tank 1 is exhausted, no more carbon dioxide gas will enter the sealing box 4, so that the speed measuring piece 13 will not rotate. The speed measuring sensor 14 detects that the rotation speed of the speed measuring piece 13 is zero, and feeds back to the controller 7. The controller 7 controls the solenoid valve 10 to open, so that the beer in the fermentation tank 1 is automatically discharged, thereby avoiding the phenomenon of excessive fermentation of beer.
[0030] Then, the top cover 2 is moved up by the handle 5, and the filter plate 9 is driven to move up by the connecting rod 8, so that the filtered impurities can be taken out of the fermentation tank 1. At the same time, the filter plate 9 can scrape off the impurities adhering to the inner wall of the fermentation tank 1, thereby realizing the cleaning function of the inner wall of the fermentation tank 1.
