Description

Technical Field

[0001] This utility model belongs to the technical field of beer brewing equipment, specifically a beer saccharification washing water acidification device. Background Technology

[0002] Beer is a low-alcohol fermented beverage made from malt, water, hops, and yeast as its core ingredients, through processes such as malting, wort filtration, boiling with added hops, cooling, and then inoculating with yeast for fermentation. With its rich flavor profile, refreshing taste, and wide versatility, beer has become one of the world's most consumed alcoholic beverages.

[0003] The saccharification process involves mixing malt with hot water and holding it at a specific temperature for a period of time. This allows the starch in the malt to be converted into fermentable sugars by enzymes, forming wort. After saccharification, the mash contains the required dissolved sugars. Then, the sugar-rich first wort is filtered and separated from the washer bed. However, the mash still adsorbs a large amount of sugar. To recover as much of this sugar as possible, the washer bed needs to be rinsed with water. This rinsing process is called washer washing, and the water used is called washer water. To avoid extracting too many undesirable substances during washer washing that could affect the beer flavor, it is necessary to strictly control the temperature, pH value, water quality, and water quantity.

[0004] Existing beer saccharification washing water acidification devices use a metered pump to draw acid from the acid storage tank into hot water, and use a pH meter to detect the pH value of the washing water to adjust the washing water to the required pH value. However, the acid cannot diffuse quickly and evenly, resulting in inaccurate pH value detection and requiring a long adjustment time. The adjustment efficiency is low and cannot be adapted to large-scale industrial production, thus failing to guarantee the consistency of beer brewing quality. Utility Model Content

[0005] To address the problems of low blending efficiency and inaccurate pH control in existing beer saccharification and washing water acidification devices, which affect the consistency of beer brewing, this utility model provides a beer saccharification and washing water acidification device.

[0006] This utility model is achieved through the following technical solution:

[0007] A beer saccharification washing waste water acidification device includes a water storage tank and an acid storage tank. A hollow motor is connected and installed at the upper end of the water storage tank. A riser is rotatably connected and installed inside the water storage tank. The inner ring of the hollow motor is driven and connected to the riser. Several liquid outlet pipes connected to the riser are connected and installed in the middle of the riser. Several stirring rods are connected and installed on the riser on both sides of the liquid outlet pipes. A support is connected and installed above the water storage tank. A metering pump is connected and installed on the support. The outlet of the metering pump is connected and installed to the riser through a rotary joint. The acid storage tank is connected to the input end of the metering pump through a pipeline. A pH meter and a controller are connected and installed on the water storage tank.

[0008] A further improvement of this utility model is that a thermometer, a water level gauge, and a heating wire are also connected and installed on the water storage tank, and an inlet pipe and an outlet pipe with a solenoid valve are connected and installed on the bottom side wall of the water storage tank.

[0009] A further improvement of this invention is that a one-way valve is connected and installed on the liquid outlet pipe.

[0010] A further improvement of this invention is that the stirring rod is plate-shaped and at a 45-degree angle to the horizontal plane.

[0011] A further improvement of this utility model is that the stirring rods on both sides of the liquid outlet pipe have opposite inclination angles. When rotating, the upper stirring rod pushes the washing water in the storage tank upward, while the lower stirring rod pushes the washing water in the storage tank downward.

[0012] A further improvement of this invention is that several pH meters are evenly distributed in different positions of the water storage tank.

[0013] A further improvement of this utility model is that the water storage tank body is provided with a heat insulation layer.

[0014] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0015] In operation, hot water at a suitable temperature is poured into the storage tank. A pH meter detects the pH value of the hot water and transmits the signal to the controller. Upon receiving the signal, the controller starts a metering pump to draw acid from the acid storage tank into a riser pipe. The acid then flows from the riser pipe into the outlet pipe and back into the storage tank. Simultaneously, a hollow motor is started, rotating the outlet pipe and a stirring rod, causing the acid to spray out in a swirling motion. The stirring rod agitates the hot water, accelerating the uniform dispersion of the acid. The pH meter detects the pH value of the hot water. When the pH value drops to the required range, the controller stops the metering pump, while the hollow motor continues to rotate, ensuring the washing water is evenly mixed. This device, by adding acid in a rotating manner at the center of the storage tank while simultaneously providing effective stirring, greatly improves the efficiency of washing water preparation. It also makes the pH meter readings more accurate, ensuring a consistent pH value in the washing water within the storage tank, thus guaranteeing a consistent flavor in the brewed beer.

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] like Figure 1-3 As shown, a beer saccharification washing waste water acidification device includes a water storage tank 1 and an acid storage tank 2 made of 304 stainless steel. A hollow motor 3, model GF-555 DC hollow shaft geared motor, is bolted to the upper end of the water storage tank 1. A hollow stainless steel riser 5 is rotatably connected inside the water storage tank 1. A pressure relief valve is connected to the top of the water storage tank 1 to balance the air pressure inside the tank and ensure the smooth addition of clean water and acid. The inner ring of the hollow motor 3 is driven by the riser 5. Six outlet pipes 6, which are connected to the riser 5, are circumferentially connected to the middle of the riser 5. Four stirring rods 7 are connected and installed on the upper and lower risers 5. A support 8 is connected and installed on the top of the water storage tank 1. A metering pump 9 is bolted to the support 8. The outlet end of the metering pump 9 is connected to the riser 5 through a rotary joint 4. The rotary joint 4 is a stainless steel rotary joint of model Xintian XTHD-CY. The acid storage tank 2 is connected to the input end of the metering pump 9 through the pipe 10. A food-grade pH meter 11 is embedded in the side wall of the water storage tank 1, and a PLC controller 12 is connected and installed on the outer wall of the water storage tank 1. The controller 12 is electrically connected to the pH meter through a data line.

[0023] In use, hot water at a suitable temperature is poured into water tank 1, and acid tank 2 is filled with acid solution. pH meter 11 detects the pH value of the hot water and transmits the signal to controller 12. After receiving the signal, controller 12 starts metering pump 9 to draw acid solution from acid tank 2 into riser pipe 5 through pipe 10. Acid solution is transferred from riser pipe to outlet pipe 6 and flows into water tank 1. At the same time, hollow motor 3 is started to rotate, driving outlet pipe 6 and stirring rod 7 to rotate together, so that acid solution is sprayed out from outlet pipe 6 while rotating. Stirring rod 7 agitates the hot water to accelerate the uniform dispersion of acid solution. pH meter detects the pH value of hot water. When the pH value is detected to drop to the required range, controller 12 controls metering pump 9 to stop working, and hollow motor 3 continues to rotate to make the washing water evenly agitated. This device greatly improves the efficiency of adding acid by rotating it at the center of the water storage tank 1, while the stirring rod 7 effectively stirs the water. It also makes the pH meter 11 more accurate, ensuring that the pH value of the water in the water storage tank 1 is consistent, thus ensuring that the brewed beer has a consistent flavor.

[0024] The water storage tank 1 is also equipped with a thermometer 13, a water level gauge 14, and a heating wire 15. The water level gauge 14 is a MIK-RD901 / 902 high-frequency radar level gauge, which measures the water level without contact. The bottom side wall of the water storage tank 1 is connected to an inlet pipe 16 and an outlet pipe 17 with a solenoid valve 19. The solenoid valve 19, thermometer 13, water level gauge 14, and heating wire 15 are all electrically connected to the controller 12 via a data line. When the water level gauge 14 detects that the washing water is used up, it transmits a signal to the controller 12. The controller 12 controls the opening of the solenoid valve 19 on the inlet pipe 16, allowing clean water to enter the storage tank 1. At this time, the solenoid valve 19 on the outlet pipe 16 is in the closed state. The thermometer 13 detects the water temperature. When the temperature is lower than the set temperature, the heating wire 15 is activated to heat the water. When the water reaches the set water level, the water level gauge 14 detects this and transmits a signal to the controller 12 to close the solenoid valve 19 and stop adding clean water. This can realize automatic control of continuous addition of clean water and keep the temperature of the washing water in a suitable range of 76-80 degrees Celsius, improve the speed of washing water preparation, improve the quality of rinsing the mash, and ensure the stability of the brewed product.

[0025] The outlet pipe 6 is equipped with a one-way valve 18. This prevents the washing water from entering the acid solution and slowly dilutes the acid solution in the riser pipe 5 into the water storage tank 1 through osmotic pressure, thus affecting the pH value of the washing water and causing the brewed beer to have an unstable flavor.

[0026] The stirring rod 7 is plate-shaped and angled at 45 degrees to the horizontal plane. The plate-shaped stirring rod 7 increases the contact area with the washing water, improving the stirring efficiency. The 45-degree angled stirring rod 7 pushes the washing water axially, allowing the acid to diffuse more quickly throughout the storage tank, improving the mixing efficiency and making the pH value of the washing water more accurate.

[0027] Among them, the stirring rods 7 on both sides of the outlet pipe 6 have opposite inclination angles. When rotating, the upper stirring rod 7 pushes the washing water in the water storage tank 1 upward, and the lower stirring rod 7 pushes the washing water in the water storage tank 1 downward, so that the washing water in the entire water storage tank 1 is circulated and the diffusion of acid is accelerated.

[0028] Several pH meters 11 are evenly distributed at different locations in the water storage tank 1. By detecting the pH value measured by the pH meters 11 at different locations, it is determined whether the acid solution is mixed evenly. When there is a large deviation in the pH value at different points, it indicates that it has not been mixed evenly and needs to be stirred until the acid solution is mixed evenly. This ensures that the washing water is mixed evenly while maintaining a certain mixing efficiency, thus ensuring the quality of beer brewing and the consistency of the product.

[0029] The water storage tank 1 is equipped with an insulation layer. This layer can keep the washing water warm, reduce heat loss, save energy, lower production costs, and prevent the water temperature from affecting the environment and causing other adverse effects.

[0030] In use, hot water at a suitable temperature is poured into water tank 1, and acid tank 2 is filled with acid solution. pH meter 11 detects the pH value of the hot water and transmits the signal to controller 12. After receiving the signal, controller 12 starts metering pump 9 to draw acid solution from acid tank 2 into riser pipe 5 through pipe 10. The acid solution is then transferred from riser pipe to outlet pipe 6 and flows into water tank 1. At the same time, hollow motor 3 is started to rotate, driving outlet pipe 6 and stirring rod 7 to rotate together, causing the acid solution to rotate and spray out from outlet pipe 6. Stirring rod 7 agitates the hot water to accelerate the uniform dispersion of acid solution. pH meter detects the pH value of hot water. When the pH value is detected... When the water level drops to the required range, controller 12 stops the metering pump 9, while the hollow motor 3 continues to rotate, ensuring the washing water is evenly mixed. Once the washing water is used up, the water level gauge 14 detects this and transmits a signal to controller 12, which opens the solenoid valve 19 on the inlet pipe 16, filling the storage tank 1 with clean water. The water level gauge 14 detects the water volume and, in conjunction with the pH meter, detects the pH value. Upon receiving the signal, controller 12 analyzes the water volume and pH value to calculate the required amount of acid solution, controlling the metering pump 9 to pump the necessary acid solution for precise mixing. Simultaneously, the heating wire 15 heats the clean water. This device, by adding acid solution while rotating at the center of the storage tank 1, along with effective stirring by the stirring rod 7, significantly improves the mixing efficiency of the washing water and makes the pH meter 11's detection more accurate, ensuring a consistent pH value in the washing water within the storage tank 1 and guaranteeing a consistent flavor in the brewed beer.

[0031] The controller 12 can be a common PLC controller. There is a heat insulation pad between the controller 12 and the water storage tank 1 to prevent high temperature from affecting the normal operation of the controller 12. For example, the Siemens S7-1500 series can be used. By setting the program, the washing water with suitable temperature and pH value can be continuously adjusted to improve the quality and efficiency of washing water preparation.
