Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of beer production, in particular to a coupled interlocking automatic deoxygenation system. Background Art
[0002] The oxygen content in beer directly impacts its quality. Oxygen accelerates beer spoilage and shortens its shelf life, creating significant risks for beer manufacturers. Tests have shown that when the oxygen content reaches 0.8mg / L, beer begins to damage beverage equipment; at 1.5mg / L, beer becomes significantly damaged; and above 2.5mg / L, beer rapidly deteriorates. Many factors can cause beer to absorb oxygen during the beer production process, including the high-concentration dilution system, the backup gas pipeline and purity of the beer tank, the filtration system, the filling system, the air content in the bottleneck, and unstable bottle pressure relief.
[0003] Craft beer equipment is relatively small, and most beer lines are stainless steel, connected by hoses or jumper panels. During beer filtering or filling, different fermentation tanks or sake tanks need to be switched. During this process, outside air inevitably enters the lines, causing oxygenation and affecting the quality of the beer. Utility Model Content
[0004] The purpose of the utility model is to provide a coupled interlocking automatic deoxygenation system to solve the problem of pipeline oxygenation during the switching of fermentation tanks and improve the quality of brewed beer.
[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:
[0006] A coupled interlocked automatic deoxygenation system comprises a buffer tank connected to a beer pipeline and a fermentation tank, a nitrogen pipeline, a deoxygenated water pipeline and a sewage pipeline. The top of the buffer tank is provided with a nitrogen inlet connected to the nitrogen pipeline, the middle of the buffer tank is provided with an inlet connected to the fermentation tank and the deoxygenated water pipeline, and the bottom of the buffer tank is provided with an outlet connected to the beer pipeline and the sewage pipeline. The nitrogen pipeline, deoxygenated water pipeline, sewage pipeline, fermentation tank and beer pipeline are respectively provided with a first valve, a second valve, a third valve, a fourth valve and a fifth valve. The top of the buffer tank is provided with a breathing valve.
[0007] Furthermore, a cleaning pipeline is included. A cleaning port connected to the cleaning pipeline is provided in the middle of the buffer tank, and a sixth valve is provided on the cleaning pipeline.
[0008] Furthermore, a connecting pipeline communicating with the cleaning port is provided inside the buffer tank, a plurality of cleaning heads are provided on the connecting pipeline, and a plurality of spray holes are provided around the upper edge of the cleaning head.
[0009] Furthermore, the cleaning pipeline is connected to the hydrogen peroxide pipeline.
[0010] Furthermore, a pressure gauge is provided on the top of the buffer tank.
[0011] Furthermore, liquid level sensors are respectively provided at the top and bottom of the buffer tank.
[0012] Furthermore, the inlet and the sewage pipe are respectively provided with conductivity sensors.
[0013] Furthermore, the buffer tank adopts a double-layer reactor structure, and a second insulation layer is provided on the outside of the buffer tank.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. After switching the fermentation tank valve, open the fourth valve first and close the other valves. Pour a small amount of beer into the buffer tank through the tank to exhaust the air in the pipe connecting the fermentation tank to the inlet into the buffer tank to prevent oxygen from staying in the pipe connecting the fermentation tank and the inlet, thereby improving the quality of the brewed beer.
[0016] 2. Open the first valve and close the other valves to fill nitrogen into the buffer tank. The nitrogen will squeeze the air inside the buffer tank, causing the air inside the buffer tank to be discharged from the breathing valve at the top. At the same time, due to the relatively stable chemical properties of nitrogen, a small amount of residual nitrogen will not affect the quality of the beer, thereby improving the quality of the brewed beer. After the buffer tank is filled with nitrogen, close the first valve and open the second valve to fill the buffer tank with deoxygenated water. During this period, due to the lower density of nitrogen and air than deoxygenated water, the nitrogen and residual air in the buffer tank float to the top of the buffer tank and are discharged from the buffer tank through the breathing valve, thereby removing the air that entered during the valve switching process, improving the quality of the brewed beer, and maintaining the pressure balance in the buffer tank.
[0017] 3. After the deoxygenated water fills the tank, close the second valve and open the fourth valve to fill the buffer tank with beer through the fermentation tank and the inlet. At the same time, open the third valve to drain the deoxygenated water. In addition, the time for opening and closing the valves is calculated according to the pipeline flow, and a certain amount of time is reserved to ensure that the deoxygenated water is fully discharged from the sewage pipe. Then open the fifth valve and connect it to the beer main pipeline to remove the deoxygenated water added during the deoxygenation process. In addition, a small amount of residual deoxygenated water can reduce the impact of oxygen on beer and improve the stability of beer. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the fifth valve 14 is opened to connect to the beer main pipeline to remove the deoxygenated water added during the deoxygenation process. In addition, a small amount of residual deoxygenated water can reduce the impact of oxygen on beer and improve the stability of beer.
