[0002] The mixer is one of the key equipment in the carbonated beverage production line. It is used to accurately mix water, syrup and CO2 gas in proportion to produce beverages that meet the sugar content and gas content requirements of the formula. In the production process of carbonated beverages, the syrup regulating valve and the CO2 regulating valve play a key and important role; based on the performance of various regulating valves and the recommended valve opening value with controllable adjustability, it is generally between 20% and 80%. As shown in the attached manual Figure 1 As shown in the figure, in the conventional regulation mode, syrup regulation and CO2 gas regulation are each regulated by a regulating valve, and the valve opening generally operates smoothly in a certain section between 20% and 80% to achieve stable sugar content and CO2 gas content index values of the beverage. Although this regulation mode is sufficient for processing one or several similar formula products, with the increasing variety of beverage formulas in the same beverage production line and the increasing differentiation of production capacity of different formula product production lines, it is becoming more and more common. The mode of using a regulating valve to control the original syrup and CO2 regulation can no longer meet the production line requirements under the new situation, especially for large production lines of 36,000L / h and above. Therefore, it is urgent to study a dual-valve regulation and proportioning system for a mixer to solve the above problems. Utility Model Content

[0019] The specific working principle of the utility model is:
[0020] Step 1: Pump the deoxygenated water out of the deoxygenated water storage tank 101 through the water pump 104, and the deoxygenated water flows through the water flow meter 105 to form an instant flow signal data to be transmitted to the main control PLC;
[0021] Step 2, the syrup pump 107 extracts the syrup in the syrup storage tank 102, and the syrup is sent to the syrup regulating main valve 109 and the syrup regulating sub-valve 110 through the syrup flowmeter 108 and the check valve 111 in turn. The main control PLC calculates the theoretical required syrup flow rate according to the input formula sugar content requirement and compares it with the real-time measurement value of the syrup flowmeter 108. Then the main control PLC uses the comparison result to adjust the size of the valve opening of the syrup regulating main valve 109 and the syrup regulating sub-valve 110, thereby accurately controlling the required amount of syrup to be added; wherein, the specific adjustment method of the syrup regulating main valve 109 and the syrup regulating sub-valve 110 is: when the production line needs to provide full production capacity or the syrup flow calculated by the main control PLC requires the valve opening of the syrup regulating valve to be greater than 80%, then at this time, the syrup regulating main valve 109 and the syrup regulating sub-valve 110 work simultaneously, and both valves are at 2 The valve operates smoothly in a section between 0% and 80% to avoid the single valve valve working in the sensitive control area with an opening greater than 80%; when the production line only needs to provide the minimum production capacity or the syrup flow calculated by the PLC requires the valve opening of the syrup regulating valve to be less than 20% or less, then only one inlet end of the syrup regulating main valve 109 is closed, and the two inlet ends and one outlet end of the syrup regulating auxiliary valve 110 are in a passage state. At this time, all the required syrup flow is only regulated and controlled by the syrup regulating auxiliary valve 110, and the valve operates smoothly in a section between 20% and 80%, avoiding the single valve valve working in the sensitive and difficult-to-control control area with an opening less than 20% or even lower. Through the selection and control of the valve opening, the regulating valve always works in a good and easy-to-control range, so that the ratio accuracy of syrup and water is strictly controlled within the target range, which fully meets the needs of wide production capacity and multiple recipes of the production line;
[0022] Step 3. The semi-finished beverage with the completed sugar and water ratio enters the CO2 proportioning unit 2 to complete the carbonization process of the beverage; the main control PLC calculates the theoretical amount of CO2 required to be added based on the total amount of liquid measured by the aforementioned syrup flowmeter 108 and the water flowmeter 105, and compares it with the real-time measurement values of the CO2 main flowmeter 206 and the CO2 sub-flowmeter 208. The main control PLC adjusts the valve opening of the CO2 regulating main valve 207 and the CO2 regulating sub-valve 209 based on the comparison result, and then accurately controls the required CO2 gas flow rate to be mixed in, and accurately implements the formula; wherein, the specific adjustment method of the CO2 regulating main valve 207 and the CO2 regulating sub-valve 209 is: when the production line needs to provide full production capacity or the CO2 flow calculated by the main control PLC requires the valve opening of the CO2 regulating valve to be greater than 80%, then at this time the CO2 regulating main valve 207 and the CO2 regulating sub-valve 20 9 work simultaneously, and make both valves operate smoothly in a certain section between 20% and 80%, so as to avoid the single valve valve operating in the sensitive control area with an opening greater than 80%; when the production line only needs to provide the minimum production capacity or the CO2 flow calculated by the main control PLC requires the valve opening of the CO2 regulating valve to be less than 20% or less, then the CO2 regulating main valve 207 is closed and the CO2 regulating sub-valve 209 is opened. At this time, all the required CO2 flow is only regulated and controlled by the CO2 regulating sub-valve 209, and the valve operates smoothly in a certain section between 20% and 80%, avoiding the single valve valve operating in the sensitive and difficult-to-control control area with an opening less than 20% or even lower; and, through the selection and control of the valve opening, the regulating valve always operates in a good and easy-to-control range, so that the ratio accuracy of CO2 and liquid is strictly controlled within the target range, thereby improving the stability of equipment operation;
[0023] Step 4: The CO2 gas with precise flow control enters the CO2 injector 210 to carry out the carbonization process of the beverage. The final product enters the finished product storage tank 301 through the capacity control valve 303 for short-term storage and is subsequently sent to the filling machine for filling operation.
[0024] In summary, this dual-valve ratio adjustment system improves the ratio accuracy and ratio stability of syrup, water and CO2 gas, and avoids the sensitive and difficult-to-control operating range of the regulating valve. It fully meets the needs of wide production line capacity and multiple formulas, and provides control guarantee for the stable production of large production lines of 36,000L / h and above.
[0025] In addition, it should be noted that: this dual-valve regulating proportioning system is also suitable for mixing with other liquid substances and mixing proportioning of gas dissolved in liquid substances, which is set according to specific applications and actual needs.
