Description

Technical Field

[0001] The utility model relates to the technical field related to beer fermentation tanks, in particular to a multifunctional fermentation tank top assembly. Background Art

[0002] The current beer fermentation tank (Announcement No.: CN213447046U) has the following inconveniences when in use:

[0003] Currently, many beer fermentation tanks utilize mechanical safety valves and vacuum control valves on their roofs, typically fixed directly to the tank flange. Pressure transmitters collect signals and control automatic exhaust valves connected to the CIP / CO2 lines. However, when the foam generated by fermentation exceeds the height of the purge ball, the CO2 cannot be discharged through the purge ball and must be discharged through the mechanical safety valve. This not only wastes some of the functionality of the pressure transmitter and automatic exhaust valve, but also shortens the life of the mechanical safety valve.

[0004] 2. The industry has not paid enough attention to the problem of low utilization rate of fermentation tank top components. The usual approach is to increase the height of the fermentation tank cylinder to keep the foam below the cleaning ball, which increases the cost of the tank and the difficulty of operation.

[0005] 3. The current fermentation tank top device is not ideal for CO2 emission treatment when the foam exceeds the cleaning ball. Utility Model Content

[0006] The main purpose of the utility model is to provide a multifunctional fermentation tank top assembly, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A multifunctional fermentation tank top assembly includes a fermentation tank body, a tank top flange disposed above the fermentation tank body, a pressure transmitter disposed above the tank top flange, a CIP pipe / CO2 exhaust pipe disposed above the tank top flange, an exhaust cavity disposed within the CIP pipe / CO2 exhaust pipe, a plastic ball disposed within the exhaust cavity, a mechanical vacuum valve disposed at the top of the exhaust cavity, a flushing pipe disposed within the left side of the CIP pipe / CO2 exhaust pipe, and a mechanical safety valve disposed at the left end of the CIP pipe / CO2 exhaust pipe. A cleaning ball is connected to the bottom end of the plastic ball.

[0009] Preferably, a cleaning ball is connected to the bottom end of the plastic ball.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The new fermenter top assembly features an additional vent chamber on the tank top flange. This vent chamber houses the CIP / CO2 exhaust pipe, and a plastic ball acts as a float to control the vent. When CO2 accumulates above a certain level within the fermenter, the ball drops onto a support, allowing the CO2 to escape through the CIP / CO2 exhaust pipe.

[0012] 2. Unlike traditional mechanical safety valves, the new component incorporates a pressure transmitter that accurately collects pressure signals within the fermenter and controls the opening of the automatic exhaust valve. This means that even if the foam generated by fermentation exceeds the cleaning ball, the CO2 can still be automatically discharged through the CIP pipe / CO2 exhaust pipe without relying on a mechanical safety valve.

[0013] 3. When cleaning the tank, the pressure of the CIP liquid will cause the plastic ball to float up and block the exhaust port, ensuring that the cleaning liquid passes through the cleaning ball to clean the tank and clean the mechanical safety valve and its connecting pipes at the same time. This design prevents the problem of foam blocking the exhaust channel during the cleaning process. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example

[0020] See also Figure 1 , the utility model provides a technical solution:

[0021] A multifunctional fermentation tank top assembly includes a fermentation tank body 1, a tank top flange 2 disposed above the fermentation tank body 1, a pressure transmitter 3 disposed above the tank top flange 2, a CIP pipe / CO2 exhaust pipe 4 disposed above the tank top flange 2, an exhaust cavity 5 disposed within the CIP pipe / CO2 exhaust pipe 4, a plastic ball 6 disposed within the exhaust cavity 5, a mechanical vacuum valve 7 disposed at the top of the exhaust cavity 5, a flushing pipe 9 disposed within the left side of the CIP pipe / CO2 exhaust pipe 4, and a mechanical safety valve 8 disposed at the left end of the CIP pipe / CO2 exhaust pipe 4. A cleaning ball 10 is connected to the bottom end of the plastic ball 6.

[0022] The fermentation tank top assembly of the present invention comprises the following parts:

[0023] Increase of exhaust cavity

[0024] The fermenter's top flange features a vent chamber, which houses a CIP / CO2 exhaust pipe. This vent chamber design allows excess CO2 to be discharged directly from the tank through the pipe inside the chamber, without relying on a mechanical safety valve. This design prevents CO2 from accumulating above the foam layer, ensuring safe operation of the fermenter.

[0025] Plastic ball float device

[0026] A plastic ball acts as a float within the exhaust chamber. During normal operation, the ball falls, allowing CO2 to escape smoothly through the CIP / CO2 exhaust pipe. When the tank needs to be cleaned, the pressure from the CIP fluid causes the ball to rise and block the exhaust port, preventing the cleaning fluid from escaping through the exhaust pipe. This device effectively prevents excessive foaming during fermentation, which can lead to poor exhaust.

[0027] Automatic exhaust control system

[0028] The system combines a pressure transmitter with an automatic exhaust valve. The pressure transmitter collects real-time pressure signals from the tank and controls the opening of the automatic exhaust valve based on the signal. This ensures that even if the foam generated by fermentation exceeds the cleaning ball, the CO2 can be discharged through the automatic exhaust valve without relying on the mechanical safety valve, thus extending the service life of the mechanical safety valve.

[0029] Foam control design

[0030] To address situations where fermentation foam might exceed the cleaning ball, the present invention incorporates an additional exhaust chamber and an automatic control system to effectively control the foam, avoiding the exhaust issues associated with traditional tank top assemblies in this situation. This design ensures smooth CO2 discharge without increasing the tank height.

[0031] Beneficial effects

[0032] Improve CO2 emission efficiency: The new tank top component is equipped with an exhaust chamber and a plastic ball float device to achieve smooth CO2 discharge when the fermentation foam exceeds the cleaning ball, avoiding the problem of poor exhaust in traditional components.

[0033] Extend the life of mechanical components: Since CO2 emissions no longer rely on mechanical safety valves, the burden on mechanical safety valves is reduced, thereby extending their service life and reducing maintenance costs.

[0034] Reducing tank production costs: By effectively controlling foam emissions, the present invention avoids the need to increase the height of the fermentation tank barrel, saving material costs while reducing the difficulty of production and operation of the fermentation tank.

[0035] Improve the automation level of the fermentation process: Combined with the automatic exhaust control system, the present invention improves the automation level of the fermentation process, making the fermentation process more stable and controllable, meeting the needs of modern brewing technology.
