Description

Technical Field

[0001] This invention belongs to the field of carbonated beverage production, specifically an integrated system of carbonation tank and filling cylinder for a mixing machine. Background Technology

[0002] The mixing unit is one of the key pieces of equipment in carbonated beverage production. Located upstream of the filling machine, it provides the filling liquid required by the filling machine. In the design and layout of conventional carbonated beverage production lines, the upstream mixing unit and the downstream filling machine are generally located at different horizontal positions on the same plane and are connected by several sanitary stainless steel pipes of different lengths and dimensions. To overcome the pressure resistance of the pipes and to form the necessary conveying pressure, a booster pump is often configured for the mixing unit to pump the material to the filling machine.

[0003] To ensure a stable filling process, downstream filling machines typically use filling cylinders or feed tanks as pressure-stabilizing buffer containers to provide a stable source of liquid for the filling valves.

[0004] Therefore, in the existing technology, the conventional way of supplying liquid to the filling machine by the mixing machine is generally as follows: the mixing machine carbonization tank sends the liquid to the filling cylinder or feed tank of the filling machine through the discharge pump and the flow control valve, and then distributes it to each filling valve for filling operation.

[0005] The above technical solutions increase energy consumption due to the increased number of intermediate steps when filling carbonated beverages, and the overall layout requires a large amount of space.

[0006] Therefore, this invention proposes an integrated system for the carbonization tank and filling cylinder of a mixing machine. Summary of the Invention

[0007] The purpose of this application is to provide an integrated system of carbonation tank and filling cylinder for a mixing machine, which solves the problem that the addition of intermediate steps increases energy consumption and the overall layout requires a lot of space when filling carbonated beverages in the prior art.

[0008] To achieve the above objectives, this application provides an integrated system for the carbonization tank and filling cylinder of a mixing machine, including a pneumatic butterfly valve; a horizontal carbonization tank; a beverage inlet flow control valve; a pressure transmitter with analog output; a level gauge with analog output; a CO2 inlet flow regulating valve; a CO2 discharge valve; a CO2 inlet switch valve; a CO2 to filling machine pneumatic control valve; and a carbonization tank outlet pneumatic control valve.

[0009] The horizontal carbonization tank adopts a horizontal design and includes: a feed inlet; a discharge outlet; a CO2 inlet; a CO2 outlet; a pressure gauge interface; and a level gauge interface.

[0010] Among them, the beverage inlet flow control valve is connected to the inlet and is used to adjust the inlet flow rate according to the detection value of the level gauge with analog output;

[0011] The carbonization tank outlet gas control valve is connected to the outlet port to provide the required injection liquid to the downstream injection machine unit;

[0012] The CO2 inlet flow regulating valve is connected to the CO2 inlet and is used to adjust the intake volume based on the detection value of the pressure transmitter with analog output.

[0013] The CO2 control valve of the filling machine is connected to the CO2 outlet and is used to provide the back pressure gas required for the filling container to the downstream filling machine unit.

[0014] Preferably, it also includes an upstream sugar water proportioning unit; a CO2 addition unit; a filling machine unit and a control unit.

[0015] Preferably, the product liquid, prepared by the sugar water proportioning unit and the CO2 addition unit, enters the horizontal carbonization tank through pipelines and a beverage inlet flow control valve.

[0016] The liquid level inside the tank is detected in real time by a level gauge with analog output, and the result signal is transmitted to the control unit.

[0017] Preferably, the control unit compares the real-time detected value of the level gauge with analog output with the set value;

[0018] When the detected value is greater than the set value, the control unit reduces the valve opening of the beverage inlet flow control valve.

[0019] When the detected value is less than the set value, the control unit increases the valve opening of the beverage inlet flow control valve.

[0020] Preferably, during the liquid inlet process, the beverage inlet flow control valve is linked with the signal of the pressure transmitter with analog output. The 4-20mA analog signal detected by the pressure transmitter in real time is converted into a pressure value and then transmitted to the control unit.

[0021] The control unit compares the pressure value with the set value. When the pressure value is greater than the set value: the CO2 inlet valve is closed and the CO2 outlet valve is opened to release gas and reduce pressure until the pressure inside the tank reaches the set value.

[0022] When the pressure value is less than the set value: close the CO2 discharge valve and keep the CO2 inlet switch valve open, increase the valve opening of the CO2 inlet flow regulating valve to supplement more CO2 gas into the tank until the pressure in the tank reaches the set value.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The conventional method of supplying liquid to the filling machine by the mixing machine is as follows: the mixing machine's carbonization tank sends the liquid to the filling cylinder or feed tank of the filling machine through the discharge pump and flow control valve, and then distributes it to each filling valve for filling operation.

[0025] The carbonization tank structure and process of the mixing machine in this integrated system can directly supply the liquid from the carbonization tank to the distributor of the filling machine and distribute it to each filling valve. This eliminates intermediate links such as the booster pump of the mixing machine, the filling cylinder or feed tank of the filling machine, and the CO2 supply system. While ensuring the stable liquid supply conditions required by the filling machine, the overall layout is compact and saves space. At the same time, the low-temperature filling of carbonated beverages reduces intermediate links and can save energy. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please refer to the details. Figure 1 An integrated system for a carbonization tank and filling cylinder of a mixing machine, the integrated system includes a pneumatic butterfly valve 1; a horizontal carbonization tank 2; a beverage inlet flow control valve 3; a pressure transmitter with analog output 4; a level gauge with analog output 5; a CO2 inlet flow regulating valve 6; a CO2 discharge valve 7; a CO2 inlet switch valve 8; a CO2 to filling machine pneumatic control valve 9; and a carbonization tank outlet pneumatic control valve.

[0034] Furthermore, the carbonization tank and filling cylinder integrated system of the mixing machine also includes an upstream sugar water proportioning unit 11; a CO2 addition unit 12; a filling machine unit 13; and a control unit 14.

[0035] It should be noted that the horizontal carbonization tank adopts a horizontal design, which is beneficial for achieving the required elevation of the entire machine. On the other hand, the horizontal structure also helps to expand the upper space of the liquid inside the tank. Compared with a vertical tank, this helps to reduce the pressure changes inside the tank caused by the increase or decrease of the same volume of liquid.

[0036] In this application, the horizontal carbonization tank includes a feed inlet 15; a discharge outlet 16; a CO2 inlet 17; a CO2 outlet 18; a pressure gauge interface 19; and a level gauge interface 20.

[0037] The beverage inlet flow control valve 3 is connected to the inlet 15 and adjusts the inlet flow rate based on the detection value of the level gauge 5 with analog output during operation. The carbonization tank outlet gas control valve is connected to the outlet 16 and provides the required filling liquid to the downstream filling machine unit 13 during operation. The CO2 inlet flow regulating valve 6 is connected to the CO2 inlet 17 and adjusts the inlet flow rate based on the detection value of the pressure transmitter 4 with analog output during operation. The CO2 to filling machine gas control valve 9 is connected to the CO2 outlet 18 and is used to provide the back pressure gas required for the filling containers to the downstream filling machine unit 13. All components are connected by stainless steel sanitary pipes.

[0038] During operation, the pressure inside the horizontal carbonization tank 2 is set according to the filling pressure required by the filling machine. The pressure difference caused by the weight of the liquid formed by the elevation H of the carbonization tank body is used to control the flow rate of the filling valve. The liquid T in the horizontal carbonization tank 2 is sent to the filling machine unit 13 through the control switch of the pneumatic butterfly valve 1. During operation, the product liquid prepared by the two functional units of sugar water proportioning unit 11 and CO2 addition unit 12 enters the horizontal carbonization tank 2 through the pipeline and beverage inlet flow control valve 3. At this time, the liquid level in the tank is detected in real time by the level gauge 5 with analog output and the result signal is transmitted to the control unit 14. The control unit compares this value with the set value. According to the comparison result: when the detected value is greater than the set value, the control unit 14 reduces the valve opening of the beverage inlet flow control valve 3; when the detected value is less than the set value, the control unit 14 increases the valve opening of the beverage inlet flow control valve 3. Thus, the liquid level in the horizontal carbonization tank 2 is stabilized.

[0039] When the CO2 inlet valve 8 is opened, CO2 gas enters the horizontal carbonization tank 2 through the CO2 inlet flow regulating valve 6, creating a certain back pressure inside the tank. Changes in the liquid level during the liquid inlet process also cause changes in the tank pressure. At this time, the beverage inlet flow control valve 3 is linked to the analog output pressure transmitter 4. The 4-20mA analog signal detected in real time by the pressure transmitter is converted into a pressure value and transmitted to the control unit 14. The control unit compares this value with the set value. When the detected value is greater than the set value: the CO2 inlet valve 8 is closed, and the CO2 exhaust valve 7 is opened to release gas and reduce pressure until the tank pressure reaches the set value; when the detected value is less than the set value: the CO2 exhaust valve 7 is closed while the CO2 inlet valve 8 remains open, and the opening of the CO2 inlet flow regulating valve 6 is increased to allow more CO2 gas to enter the tank until the tank pressure reaches the set value. The CO2 gas inside the tank is sent to the CO2 filling machine's pneumatic control valve 9, which allows the filling machine unit 13 to obtain the same CO2 back pressure as the horizontal carbonization tank 2.

[0040] Furthermore, because the horizontal carbonization tank 2 has a fixed physical elevation height H compared to the filling machine unit 13, this physical elevation height H provides additional feeding pressure to the filling valve, and this pressure is only related to H. Therefore, through this system, the filling unit can obtain a very stable supply of liquid with both flow rate and pressure, ensuring the realization of smooth and high-speed filling.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
