[0032] The real-time monitoring mechanism monitors the physical and chemical indicators of the production materials during the blending process in real time, and transmits the real-time data of the physical and chemical indicators of the production materials during the blending process to the PLC.

[0033] Specifically, the physical and chemical indicators of the production materials in the blending process, assuming that Maotai-flavor liquor is an example, include:

[0034] Total acidity

[0035] Range: 1.5-3.0 g / L

[0036] Note: Detected by automatic titrator; the acidity of Maotai-flavor liquor is relatively high, which is an important component of its unique flavor;

[0037] Total ester content

[0038] Range: 2.0-3.5 g / L

[0039] Description: Detected by gas chromatography; ester compounds are the main components of liquor aroma, and a higher total ester content helps to enhance the aroma of liquor;

[0040] Methanol content

[0041] Range: ≤0.4 g / L

[0042] Note: Detected by gas chromatograph; methanol is a toxic substance and its content should be strictly controlled;

[0043] Aldehyde content

[0044] Range: ≤0.03 g / L

[0045] Note: Detected by gas chromatograph; high concentrations of aldehydes can make wine irritating and uncomfortable;

[0046] Sugar content

[0047] Range: ≤0.5 g / L

[0048] Note: Detected by gas chromatograph; Maotai-flavor liquor is generally dry and has a low sugar content;

[0049] Sulfide content

[0050] Range: ≤0.01 g / L

[0051] Note: Detected by gas chromatograph; sulfide will produce odor, and its content should be as low as possible;

[0052] pH

[0053] Range: 3.5-4.5

[0054] Note: Detected by automatic pH meter; lower pH value helps stabilize the wine and prevent secondary fermentation; temperature

[0055] Range: around 40℃

[0056] Description: Detected by temperature sensor; ensures that various aroma components can be effectively separated while ensuring the purity of the wine and the mellow taste.

[0057] Specifically, the real-time monitoring mechanism includes:

[0058] Temperature sensor, thermocouple temperature sensor, transmits data through 4-20mA current signal; it is set inside the wine tank to monitor the temperature change of production materials during the blending process in real time, and the real-time data is transmitted to the signal input end of the PLC through the signal output end;

[0059] pH sensor, automatic pH meter, choose E+H's Memosens CPS11D, set inside the wine tank to monitor the pH changes of production materials during the blending process, and the real-time data is transmitted to the signal input of the PLC through the signal output terminal;

[0060] Automatic sampler, set outside the wine tank, to sample production materials during the blending process;

The real-time data is transmitted to the signal input end of the PLC through the signal output end.

[0063] Specifically, when the temperature sensor, automatic titrator, pH sensor, and gas chromatograph included in the real-time monitoring mechanism detect that the physical and chemical indicators of the production materials in the blending process exceed the normal range of the set product safety and quality standards, an alarm message is sent to the signal input terminal of the PLC through the signal output terminal, and the alarm message is transmitted to the MHI via the PLC to display the alarm message to the staff.

[0064] Specifically, the sensor mechanism includes:

[0065] Liquid level sensor, thermocouple temperature sensor, transmits data through 4-20mA current signal, and is used to measure the liquid level of the clean water tank and alcohol storage tank during the blending process; the signal output end of the liquid level sensor is connected to the signal input end of the PLC;

[0066] Flow meter, electromagnetic flow meter, choose E+H Proline series, measure the flow rate of production materials during blending, and connect the flow meter signal output terminal to the PLC signal input terminal;

[0067] Specifically, after the signal input end of the PLC receives the information sent by the signal output end of the flowmeter, the PLC determines whether the flow rate of the production material meets the preset formula dosage requirements, and then inputs opening and closing instructions to the solenoid valve to control the flow rate of the production material during the blending process.

[0068] Example:

[0069] Taking Maotai-flavor liquor as an example, the staff inputs and saves the liquor formula into the HMI, and then transmits the formula to the PLC through the CP5611 card. The PLC controls each link of the blending process according to the received formula. Open or close the valves of each wine tank (base wine tank, soft water tank), measure the flow rate of the production materials during the blending process through the flow meter, and transmit the signal to the PLC. The PLC monitors the information uploaded by the flow meter to determine whether the preset formula dosage requirements are met, and then inputs the opening and closing instructions to the solenoid valve, and the valve controls the flow rate; start the stirring device to help different base wines and flavoring wines mix evenly; the liquid level sensor measures the liquid level of the clean water tank and the alcohol storage tank during the blending process, and monitors the storage of clean water and alcohol.

[0070] During the blending process, the real-time monitoring mechanism monitors the physical and chemical indicators of the production materials in real time, and transmits real-time data of the physical and chemical indicators of the production materials during the blending process to the PLC. The physical and chemical indicators that need to be monitored include total acidity, range: 1.5-3.0g / L, detected by automatic titrator; the acidity of sauce-flavor liquor is relatively high, which is an important part of its unique flavor; total ester content, range: 2.0-3.5g / L, detected by gas chromatograph; ester compounds are the main components of the aroma of liquor, and a higher total ester content helps to enhance the aroma of the liquor; methanol content, range: ≤0.4g / L, detected by gas chromatograph; methanol is a toxic substance and its content should be strictly controlled; aldehyde content, range: ≤0.03g / L, detected by gas chromatograph; high concentration Aldehyde substances will make the wine irritating and uncomfortable; sugar content, range: ≤0.5g / L, detected by gas chromatograph; Maotai-flavor liquor is generally dry and has a low sugar content; sulfide content, range: ≤0.01g / L, detected by gas chromatograph; sulfide will produce odor, and its content should be as low as possible; pH value, range: 3.5-4.5, detected by automatic pH meter; lower pH value helps stabilize the wine and prevent secondary fermentation; temperature, range: around 40℃; detected by temperature sensor; ensure that various flavor components can be effectively separated, while ensuring the purity of the wine and the mellow taste. These physical and chemical indicators are closely related to the product quality and product safety of liquor. The physical and chemical indicators in the blending process are transmitted through temperature sensors and thermocouple temperature sensors through 4-20mA current signals; they are set inside the wine tank to monitor the temperature changes of the production materials during the blending process in real time, and the real-time data is transmitted to the signal input end of the PLC through the signal output end; the pH sensor, automatic pH meter, select E+H's Memosens CPS11D, is set inside the wine tank to monitor the pH changes of the production materials during the blending process, and the real-time data is transmitted to the signal input end of the PLC through the signal output end; the automatic sampler is set outside the wine tank to sample the production materials during the blending process; the automatic titrator, select Tianrui Instrument's TRD-810 automatic titrator, is set outside the wine tank to monitor the total acidity of the production materials taken out by the automatic sampler, and the real-time data is transmitted to the signal input end of the PLC through the signal output end; the gas chromatograph is set outside the wine tank to monitor the total ester content, methanol content, fusel oil content, aldehyde content, sugar content, and sulfide content of the production materials taken out by the automatic sampler in real time, and the real-time data is transmitted to the signal input end of the PLC through the signal output end.The above-mentioned real-time monitoring mechanism ensures real-time monitoring of the blending process. When the temperature sensor, automatic titrator, pH sensor, and gas chromatograph detect that the physical and chemical indicators of the production materials in the blending process exceed the normal range of the set product safety and quality standards, an alarm message is sent to the signal input end of the PLC through the signal output end. The alarm message is transmitted to the MHI via the PLC to display the alarm message to the staff. The staff eliminates the adverse factors generated in the production process through the displayed alarm information, minimizes the impact of the adverse factors, reduces economic losses, and improves the quality of liquor.
