Background
The wine is the traditional culture of Chinese nationality and is a treasure in five thousand years of China civilization, but the existing Chinese liquor manufacturing industry also belongs to labor-intensive industry, the mechanization degree is low, and most liquor enterprises are in the original mode of manual operation production. In recent years, under the influence of the rising of labor cost, the increasing shortage of land resources and the national industrial policy of high efficiency and low consumption development, the Chinese liquor brewing production industry makes technological innovation and changes of the traditional production mode urgently.
The brewing industry has an old word: "producing fragrance depends on fermentation, extracting fragrance depends on distillation, and picking wine depends on wine picking workers", which shows the importance of the distillation wine picking process. In the process of distilling and picking wine, the wine yield and the wine quality of different vinasses are different, and the quality of the wine flowing at different moments of each vinasse in a retort is also different. The flow rate of the flowing wine and the alcoholic strength of the flowing wine are two important parameters in the process, and most of wineries adopt the traditional manual measurement mode at present, so that the development requirements of data generation, automation, intellectualization and fine management in the brewing industry are not met.
For flow and alcohol content measurement during liquor extraction, the following requirements are mainly set:
(1) the piping must be open so that the pressure in the piping does not affect the upstream distillation and condensation;
(2) the dynamic measurement range is large, the variation range can be from 0 to 10L/min or even higher, and the wine flowing time is an important index in production, so the flow of a few mL/min also needs to be measured more accurately;
(3) the requirement on the accuracy of accumulated flow measurement is high, the flow rate of wine is also an important index in production, and some alcohol degree measurement methods also depend on accurate accumulated flow measurement, so that the used flowmeter not only can accurately measure the real-time flow, but also has higher accuracy of accumulated flow measurement;
(4) the real-time requirement is high, and the real-time flow data of distilled liquor can be used for guiding retort loading and liquor grading, so that the flow and alcohol degree measurement must have high real-time performance.
However, the existing flow meter and alcohol meter cannot realize online real-time measurement of the flow rate and alcohol content of the wine body in an open pipeline.

The method hopes to carry out some preliminary exploration on the datamation of the white spirit brewing process link in China through research, and plays a certain role in promoting the intellectualization of the brewing production and the refinement of the production management of the white spirit industry.

Detailed Description
The diversion device for the liquor-extracting process of distilled liquor and the online measuring system and method for the flow and the alcoholic strength provided by the invention are further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, an embodiment 1 of the present invention provides a diversion device 100 for a distilled spirit picking process, where the diversion device 100 includes a guiding pipe 101, a guiding pipe 102, a first standard container 103, a second standard container 104, a first control valve 105, a second control valve 106, a third control valve 107, and a fourth control valve 108. The first control valve 105, the second control valve 106, the third control valve 107, and the fourth control valve 108 are single-channel control valves.
The inlet tube 101 includes a first leg 1011 and a second leg 1012. The first branch 1011 is suspended and spaced apart from the inlet of the first standard container 103, so that the wine body 109 can flow into the first standard container 103 from the first branch 1011. The second branch 1012 is suspended and spaced apart from the inlet of the second standard container 104, so that the wine body 109 can flow into the second standard container 104 from the second branch 1012. The first branch 1011 is suspended and spaced from the first standard container 103, so as to avoid considering the influence of the pressure or the supporting force of the first branch 1011 when the quality of the wine body 109 in the first standard container 103 is measured subsequently. The same is true of the second branch 1012 being suspended and spaced apart.
The delivery tube 102 includes a third branch 1021 and a fourth branch 1022. The first standard container 103 is suspended and spaced at the inlet of the third branch 1021, so that the wine 109 flowing out of the first standard container 103 can flow into the third branch 1021. The second standard container 104 is suspended and spaced apart from the inlet of the fourth branch 1022, so that the wine body 109 flowing out of the second standard container 104 can flow into the fourth branch 1022. The first standard container 103 is suspended and spaced from the third branch 1021, so that the influence of the supporting force of the third branch 1021 is avoided being considered when the quality of the wine body 109 in the first standard container 103 is measured subsequently. The same is true of the second standard container 104 being suspended and spaced apart.
The first control valve 105 is disposed on the first branch 1011, the second control valve 106 is disposed on the second branch 1012, the third control valve 107 is disposed at the outlet of the first standard container 103, and the fourth control valve 108 is disposed at the outlet of the second standard container 104. Specifically, a first flow guide pipe 1030 is connected to the bottom of the first standard container 103, and the third control valve 107 is disposed on the first flow guide pipe 1030; a second flow pipe 1040 is connected to the bottom of the second standard container 104, and the fourth control valve 108 is disposed on the second flow pipe 1040. The first flow guide pipe 1030 is suspended and disposed at an entrance of the third branch 1021 at intervals, and the second flow guide pipe 1040 is suspended and disposed at an entrance of the fourth branch 1022 at intervals.
When the diversion device 100 works, the first control valve 105 and the fourth control valve 108 are firstly opened, the second control valve 106 and the third control valve 107 are closed, and the wine 109 flows into the first standard container 103; when the first standard container 103 is full, the first control valve 105 and the fourth control valve 108 are closed, the second control valve 106 is opened, new wine 109 flows into the second standard container 104, and then the third control valve 107 is opened, so that the wine 109 in the first standard container 103 flows out; when the wine body 109 in the first standard container 103 completely flows out, the third control valve 107 is closed; when the second standard container 104 is full, the second control valve 106 is closed, the first control valve 105 is opened, new wine 109 flows into the first standard container 103 again, and then the fourth control valve 108 is opened, so that the wine 109 in the second standard container 104 flows out; when the wine 109 in the second standard container 104 is completely discharged, the fourth control valve 108 is closed. The above steps are repeated in a circulating way.
Referring to fig. 2, embodiment 1 of the present invention further provides an online measurement system 10 for measuring flow rate and alcohol content of distilled spirit during a process of extracting distilled spirit, wherein the measurement system 10 includes the diversion device 100, a measurement device 110 and a control device 120.
The measuring device 110 includes a first pressure sensor 111, a second pressure sensor 112, a first liquid level sensor 113, and a second liquid level sensor 114. The first pressure sensor 111 and the second pressure sensor 112 are used for measuring the mass of the wine 109 in the first standard container 103 and the second standard container 104 in real time respectively. The first liquid level sensor 113 and the second liquid level sensor 114 are respectively used for measuring the liquid level height of the wine body 109 in the first standard container 103 and the second standard container 104 in real time. The structures of the first pressure sensor 111 and the second pressure sensor 112 are not limited, and the structures may be the same or different. The first liquid level sensor 113 and the second liquid level sensor 114 are not limited in structure, and may have the same or different structures. It is understood that the first fluid level sensor 113 and the second fluid level sensor 114 may be the same fluid level sensor.
Further, the measuring device 110 further comprises a resistance sensor (not shown) for measuring the temperature of the wine 109 in the first standard container 103 and the second standard container 104. Preferably, the resistance sensor is a non-contact resistance sensor.
In one embodiment, the first pressure sensor 111 and the second pressure sensor 112 are identical in structure. The first standard container 103 is fixed to the first pressure sensor 111 by a first support mechanism (not shown), and the second standard container 104 is fixed to the second pressure sensor 112 by a second support mechanism (not shown). According to the indication of the first pressure sensor 111 and the instantaneous flow of the wine body 109, the impact of the wine body 109 flowing into the first standard container 103 is corrected, and the weight of the first standard container 103 is subtracted, namely the weight of the wine body 109 in the first standard container 103. Similarly, the weight of the wine body 109 in the second standard container 104 can be obtained.
In one embodiment, the liquid level is detected using a camera. Referring to fig. 3, the first liquid level sensor 113 includes a surface light source 1131, a light shielding strip 1132 and a camera 1133. The surface light source 1131 and the camera 1133 are respectively disposed on two sides of the first standard container 103, and the light shielding strip 1132 is disposed on one side of the surface light source 1131 close to the first standard container 103. For example, a black shielding strip 1132 is attached to the surface light source 1131. The camera 1133 photographs the surface light source 1131 and the light shielding strip 1132 through the first standard container 103 containing the wine 109. The width of the part of the light shielding strip 1132 without liquid is normal, and the width of the part with liquid is obviously widened due to the refraction effect of the liquid, so that the liquid level height of the wine body 109 can be obtained after the image processing processes such as binarization, morphological processing and statistical analysis are carried out on the width of the light shielding strip 1132 in the picture shot by the camera 1133. Fig. 4 shows a sample of photographs taken by the camera and the processing results. The first liquid level sensor 113 and the second liquid level sensor 114 have the same structure. The first liquid level sensor 113 and the second liquid level sensor 114 may be provided with one camera.
In another embodiment, the liquid level is detected by measuring electrical impedance characteristics (including resistance, capacitance, etc.). Fig. 5 and 6 show a schematic diagram and a physical photograph of an apparatus for measuring the liquid level of the wine body 109 by measuring electrical impedance characteristics, respectively. The first liquid level sensor 113 includes a first electrode 1134, a second electrode 1135 and a detecting device 1136. The first electrode 1134 and the second electrode 1135 are two strip-shaped metal sheets with the same shape, and are symmetrically adhered to two sides of the outer tube wall of the first standard container 103 at intervals. The detecting device 1136 applies an ac signal to the first electrode 1134 and the second electrode 1135 (while attenuating electromagnetic noise by using a shielding layer), and detects impedance characteristics between the first electrode 1134 and the second electrode 1135. The impedance between the first electrode 1134 and the second electrode 1135 is found to be capacitive, and the modulus | Z | of the impedance is in a relatively good inverse proportion to the liquid level in the tube. The impedance is equivalent to a series circuit of a resistor and a capacitor, and the measured equivalent series resistance R is in a better inverse proportional relation with the liquid level of the wine body 109. As shown in fig. 7, the equivalent series capacitance C has a good linear relationship with the liquid level.
In another embodiment, the liquid level is measured by ultrasound. FIG. 8 shows a schematic view of two devices for detecting liquid level by using ultrasonic waves. The first level sensor 113 includes an ultrasonic transducer 1137. The ultrasonic transducer 1137 may be mounted on the bottom or top of the first modular container 103. When the ultrasonic transducer 1137 is installed at the bottom of the first standard container 103, ultrasonic waves are emitted upwards and reflected at the liquid level of the wine body 109, so that the propagation time of the ultrasonic waves in the wine body 109 can be measured, and the liquid level height can be calculated according to the sound velocity in the liquid. When the ultrasonic transducer 1137 is installed on the top of the first standard container 103, ultrasonic waves are emitted downwards and reflected at the liquid level of the wine body 109, so that the time of the ultrasonic waves propagating in the air above the liquid level of the wine body 109 can be measured, and the liquid level height of the wine body 109 can be calculated according to the sound velocity in the air.
The control device 120 is electrically connected to the first pressure sensor 111, the second pressure sensor 112, the first liquid level sensor 113 and the second liquid level sensor 114, respectively, and is configured to obtain mass data and liquid level height data of the wine body 109 in the first standard container 103 and the second standard container 104, and calculate a flow rate and an alcohol content of the wine body 109 according to the mass data and the liquid level height data. Further, the control device 120 is connected to the first control valve 105, the second control valve 106, the third control valve 107 and the fourth control valve 108, and controls the opening and closing of the first control valve 105, the second control valve 106, the third control valve 107 and the fourth control valve 108 according to the liquid level heights of the wine bodies 109 in the first standard container 103 and the second standard container 104.
As shown in fig. 9, the control device 120 includes a computer 121, a valve control circuit 122, a sensor interface 123, and a display device 124. The valve control circuit 122, the sensor interface 123 and the display device 124 are electrically connected to the computer 121, respectively. The computer 121 is used to control the operation of the entire measuring system 10 and to calculate the flow rate and the alcohol content of the wine body 109. The computer 121 may be a Personal Computer (PC), a Microcontroller (MCU), a Programmable Logic Controller (PLC), or the like.
The flow rate of the wine body 109 may be a mass flow rate or a volume flow rate. The volume flow rate is obtained by dividing the volume of the wine bodies 109 in the standard container by the time t during which these wine bodies are collected, and the mass flow rate is obtained by dividing the mass of the wine bodies 109 in the standard container by the time t during which these wine bodies are collected. The volume is obtained by means of a level sensor and the mass of the wine body 109 is obtained by means of a pressure sensor. The time t is obtained by the computer 121. For example, taking the calculation of the volume flow rate of the wine 109 in the first standard container 103 as an example, when the computer 121 controls the first control valve 105 to open, the timing is started to obtain the time t, and the first liquid level sensor 113 reads the liquid level height in real time and obtains the volume of the wine 109 in the first standard container 103.
The method for measuring the alcoholic strength of the wine body 109 comprises the following steps: the alcohol content of the wine body 109 can be obtained by calculating the mass of the wine body, calculating the density of the wine body 109, obtaining the temperature of the wine body 109, and looking up tables according to density and temperature, an alcohol water solution density and alcohol content (alcohol content) comparison table (20 ℃) in GB 5009.225-2016 (measurement of alcohol concentration in national standard wine for food safety), and an alcohol content conversion table (conversion table of alcohol meter temperature and alcohol content (alcohol content) at 20 ℃). The computer 121 may store the comparison table and the conversion table, or may query the comparison table and the conversion table through a network.
