Description

Technical Field

[0001] This utility model relates to the field of beer production, and in particular to the field of boiling pot technology for beer production, specifically a visual boiling pot for beer brewing. Background Technology

[0002] According to patent authorization announcement number CN211814340U, a boiling kettle for beer brewing includes a boiling kettle body. The upper end of the boiling kettle body is provided with a main body cover, and the outer wall of the boiling kettle body is wrapped with a heating shell. A heating ring is installed inside the boiling kettle body. A gas guide pipe is provided inside the boiling kettle body, with one end connected to a gas guide shell, and the other end of the gas guide pipe passing through the inner wall of the boiling kettle body and located inside the heating shell. A liquid guide pipe is provided inside the boiling kettle body, and a liquid guide pipe is connected to one side of the liquid guide ring. The upper end of the gas guide shell is open, and the inner wall of the gas guide shell is provided with a circular sealing plate support. A circular gas guide shell sealing plate is glued to the upper end of the sealing plate support. Existing beer brewing boiling kettles, such as the one described above, can use steam recirculation to heat the boiling kettle body, but the gas guide pipe cannot be pressure regulated, making it inconvenient to control the pressure inside the boiling kettle body, which affects the brewing quality of the beer.

[0003] Application number CN202320644695.1 provides a boiling pot for beer brewing with a steam reflux structure, but the boiling pot lacks stirring, and the refluxed steam is also wasted. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a visual beer brewing kettle that uses the heat of steam to heat the air, thereby recovering the heat. At the same time, this air enters the tank from below, thus achieving the function of air stirring.

[0005] This utility model is achieved through the following technical solution: a visual beer brewing boiling pot includes a tank body, a heating device located inside the tank body, and a cavity located between the tank body and the outer shell. It also includes a gas box located outside the cavity and having a gas chamber, a heat exchange tube located inside the gas box wall, and a connecting pipe connecting the heat exchange tube and the cavity. An air inlet pipe connecting the gas chamber and the inner cavity of the tank body is provided on the inclined bottom wall of the tank body. A one-way pressure valve is provided on the air inlet pipe. A first piston is slidably sealed inside the gas chamber. A venting switch located above the liquid surface and connecting the inner cavity of the tank body and the cavity is also provided on the tank body.

[0006] In use, steam enters the cavity through the venting switch and then enters the heat exchange tube through the connecting pipe to heat the air in the gas box. After heating, the air in the gas box is compressed by the first piston, making the air pressure in the gas box greater than the air pressure inside the tank. This causes the air to enter the tank through the one-way pressure valve, and the gas flows from bottom to top, thus achieving the stirring effect.

[0007] Preferably, the venting switch includes a tube communicating with the inner cavity of the tank. The tube contains a baffle, a second piston that is slidably sealed within the tube, and a spring connecting the baffle and the second piston. The second piston is also connected to a second plug rod that passes through the baffle and extends out of the tube. The tube also has a first opening located between the piston and the baffle. The first opening communicates with the cavity through an air inlet pipe and has a one-way valve.

[0008] In use, when the pressure inside the tank increases, the steam inside the tank drives the second piston to move outward and compress the spring. When the piston moves between the first opening and the baffle, the steam enters the cavity from the first opening through the air inlet pipe, thus enabling the steam to enter the cavity.

[0009] Preferably, the baffle is slidably sealed inside the tube, the baffle and the second plug rod are coaxially arranged, the circumferential surface of the baffle is provided with a fixed rod that is oppositely arranged and extends outside the tube, and a fixed plate located outside the tube and fixed to the rear end of the fixed rod is bolted to the bracket outside the tube. A limiting ring is also provided inside the tube, and the limiting ring is located between the first piston and the inner cavity of the tank.

[0010] In use, this preferred solution allows for easy adjustment of the position of the baffle, i.e., the tension of the spring, by adjusting the position of the fixing plate on the bracket.

[0011] Preferably, a cylinder is provided on the outer side of the first piston to push the first piston toward the tank.

[0012] This preferred solution achieves the movement of the first piston by using a cylinder.

[0013] Preferably, the air inlet of the air chamber is connected to an air pump via an air inlet pipe, and the air inlet pipe is also provided with a first three-way valve. The other opening of the first three-way valve is connected to the feed tank, and the air inlet of the air pump is connected to a hot air storage tank.

[0014] In this preferred embodiment, the heat storage tank contains filtered, sterilized, and heated air, which facilitates the replenishment of air to the gas box while also increasing the pressure inside the gas box. At the same time, the setting of the feed tank facilitates the introduction of some vaporized additives into the gas box through air replenishment, and into the tank body through the air inlet pipe.

[0015] Preferably, two vent switches are provided, arranged opposite to each other. This preferred embodiment enhances the pressure regulation effect by using two vent switches.

[0016] The beneficial effects of this utility model are as follows: Steam enters the cavity through the venting switch and then enters the heat exchange tube through the connecting pipe to heat the air in the gas box. After heating, the air in the gas box is compressed by the first piston, making the air pressure in the gas box greater than the air pressure inside the tank. This allows the air to enter the tank through the one-way pressure valve, and the gas flows from bottom to top, thus achieving a stirring effect. When the pressure inside the tank increases, the steam inside the tank drives the second piston to move outward and compress the spring. When the piston moves between the first opening and the baffle, the steam enters the cavity from the first opening along the air inlet pipe, thus enabling steam to enter the cavity. The baffle is threaded into the tube body, making it easy to adjust the position of the baffle, i.e., adjust the tension of the spring. Attached Figure Description

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] See attached document Figure 1-3 This utility model discloses a visual beer brewing boiling pot, including a tank body 1, a heating device 2 located inside the tank body 1, and a cavity 3 located between the tank body 1 and the outer shell. The tank body 1 is provided with a raw material inlet, an inlet, and a discharge pipe. The tank body 1 is also provided with a liquid guide pipe and a liquid guide ring.

[0024] The boiling pot also includes a gas box 4 located outside the cavity 3 and having a gas chamber, a heat exchange tube located inside the wall of the gas box 4, and a connecting pipe connecting the heat exchange tube and the cavity 3. An air inlet pipe is provided on the inclined bottom wall of the tank body 1, which connects the gas chamber and the inner cavity of the tank body 1. The air inlet pipe is sealed through the outer shell and the bottom wall of the tank body 1. A one-way pressure valve is provided on the air inlet pipe, which is located inside the bottom wall of the tank body 1.

[0025] A first piston 11 is slidably connected to the air chamber, and a venting switch located above the liquid surface and connecting the inner cavity of the tank 1 and the cavity 3 is also provided on the tank body 1.

[0026] Two vent switches are provided, and the two vent switches are arranged opposite to each other. Each vent switch includes a pipe body 10 that communicates with the inner cavity of the tank body 1. The pipe body 10 is provided with a baffle 16, a second piston 12 that is slidably sealed inside the pipe body 10, and a spring 15 that connects the baffle 16 and the second piston 12. The second piston 12 is also connected with a second stop rod 14 that passes through the baffle 16 and extends to the outside of the pipe body 10. The pipe body 10 is also provided with a first opening located between the piston and the baffle 16. The first opening communicates with the cavity 3 through an air inlet pipe and is provided with a one-way valve.

[0027] The baffle 16 is slidably sealed inside the tube body 10. The baffle 16 and the second plug rod 14 are coaxially arranged. The circumferential surface of the baffle 16 is provided with a fixing rod 17 that is opposite to and extends outside the tube body 10. A fixing plate 18 located behind the fixing rod 17 is bolted to the bracket outside the tube body 10. The rear end of the fixing rod 17 is fixedly connected to the fixing plate 18. Several screw holes are opened on the bracket along the axial direction of the tube body 10. The position of the baffle 16 can be adjusted by connecting the fixing plate 18 to the screw holes at different positions. A limiting ring 13 is also provided inside the tube body 10. The limiting ring 13 is located between the first piston 11 and the inner cavity of the tank body 1.

[0028] A fixing plate 18 is provided on the support outside the tube body 10, located behind the fixing rod 17. The rear end of the fixing rod 17 is in contact with the fixing plate 18. The fixing plate 18 is bolted to the support. The setting of the fixing plate 18 restricts the position of the fixing rod 17, that is, limits the position of the baffle, and provides support for the baffle.

[0029] A cylinder 9 is provided on the outer side of the first piston 11 to push the first piston 11 toward the tank 1.

[0030] The air chamber's inflation port is connected to an air pump 6 via an inflation pipe 8. The inflation pipe 8 is also equipped with a first three-way valve 5, and the other opening of the first three-way valve 5 is connected to the feed tank. The air inlet of the air pump 6 is connected to a hot air storage tank 7.

[0031] Solenoid valves are installed in the three-way valve 5, the air inlet pipe, the heat exchange pipe, and the air filling pipe 8. Pressure sensors are also installed in the inner cavity of the tank 1, the air cavity 3, and the gas cavity. The solenoid valves, pressure sensors, and one-way pressure valves are all electrically connected to the control console. Therefore, the on / off status and pressure of each solenoid valve can be observed from the control console, enabling easy and visualized management.

[0032] When this utility model is in use, when the pressure inside the tank 1 increases, the steam inside the tank 1 drives the second piston 12 to move outward and compress the spring 15. When the piston moves between the first opening and the baffle 16, the steam enters the cavity 3 from the first opening along the air inlet pipe, thus enabling the steam to enter the cavity 3. The steam enters the cavity 3 through the venting switch and enters the heat exchange tube through the connecting pipe to heat the air in the gas box 4.

[0033] As the air inside the gas chamber 4 heats up and expands, it pushes the piston to extend away from the tank 1. When stirring is required, the drive cylinder 9 extends, causing the first piston 11 to move towards the tank 1, thereby increasing the air pressure inside the gas chamber 4. The air pressure inside the gas chamber 4 is greater than the air pressure inside the tank 1, so that this part of the air enters the tank 1 through the one-way pressure valve. The gas flows from bottom to top, thus achieving the stirring effect. When the air pressure is insufficient, the drive air pump 6 sends more air into the gas chamber 4, thereby ensuring that there is enough air entering the boiling pot.

[0034] When additional ingredients are needed, the air pump 6 supplies air to the air box 4 while simultaneously drawing the additional ingredients into the air box 4. At this time, the first cylinder 9 drives the first piston 11 to move towards the tank 1, allowing air to enter the boiling pot. This allows the additional ingredients to enter the boiling pot and move upwards, ensuring thorough mixing between the additional ingredients and the beer, thus achieving the addition of the additional ingredients.

[0035] When the pressure inside the tank 1 increases, the steam inside the tank 1 drives the second piston 12 to move outward and compress the spring 15. When the piston moves between the first opening and the baffle 16, the steam enters the cavity 3 from the first opening along the air inlet pipe, thus enabling the steam to enter the cavity 3.

[0036] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
