DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The above scheme can be used to regulate the filtration pressure of the filtering device in real time according to the viscosity characteristics and flow characteristics of the wine filtrate to maintain the stable filtration performance of the filtering device.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 , which is an exemplary flow chart of a filtration pressure control method for wine clarification according to some embodiments of the present application. The filtration pressure control method 100 for wine clarification mainly includes the following steps: In step 101, the amount of wine filtrate passing through the filtration device under different filtration pressure conditions is collected.

[0022] In specific implementation, the amount of wine filtrate passing through the filtration device under different filtration pressure conditions is collected by the sensor in the filtration device; the filtration pressure during the filtration process is measured by the pressure sensor, and the amount of wine filtrate passing through the filtration device is measured by the flow sensor. In actual implementation, the pressure sensor is usually installed at the inlet and outlet of the filter, and the flow sensor is installed in the liquid inlet pipe or the liquid outlet pipe of the filter, so as to set the data sampling frequency of the sensor. For example, data can be sampled once per second, or the frequency can be adjusted according to actual needs. The amount of wine filtrate collected by the sensor, the sampling time and the filtration pressure at the sampling time are recorded in real time by the data acquisition system.

[0023] In step 102, a filtrate volume curve of the filtering device is generated according to all wine filtrate volumes, and the jitter degree of the filtrate volume and the equivalent characteristics of the filtration pressure when the filtering device filters the wine are extracted from the filtrate volume curve. The filtrate viscosity characteristics when the filtering device clarifies the wine filtrate are determined using the jitter degree of the filtrate volume and the equivalent characteristics of the filtration pressure.

[0024] Optionally, in some embodiments, the filtrate volume curve of the filtration device is generated according to all wine filtrate volumes in the following manner, namely: Draw a scatter plot of the filtrate based on all the wine filtrate amounts; The filtrate scatter plot is subjected to curve fitting to obtain a filtrate amount curve of the filtration device.

[0025] In the specific implementation, first, the filter pressure and the corresponding wine filtrate volume at the sampling moment are obtained from all the wine filtrate volumes, so that a scatter plot can be drawn using a data analysis tool, such as Python's Matplotlib; then, an appropriate curve fitting model is selected according to the distribution of the scatter plot. The fitting model selected in this application is a linear regression model, so that curve fitting is performed using a data analysis tool, for example, using Python's Scikit-learn library for curve fitting, and based on the output of the linear regression model, a filtrate volume curve of the filtration equipment is generated, which shows the relationship between the wine filtrate volume and the filter pressure at the corresponding sampling moment, and provides the performance characteristics of the filtration equipment under different operating conditions.

[0026] Optionally, in some embodiments, the equivalent characteristics of the jitter degree of the filtrate volume and the filtration pressure when the filtration device filters wine can be extracted from the filtrate volume curve in the following manner, namely: dividing the filtrate amount curve into a plurality of filtrate sub-segments; determining the rate of change of the filtrate volume of each filtrate subsection; Determining the degree of jitter of the filtrate volume when the filtration device filters wine by using the filtrate volume change rate of all filtrate sub-segments; The equivalent characteristics of the filtration pressure when the filtration device is filtering wine are determined according to the jitter degree of the filtrate amount and the wine filtrate amount in the filtrate amount curve.

[0027] It should be noted that, in the present application, the filtrate volume change rate represents the rate of change of the wine filtrate volume; the filtrate volume jitter represents the degree of jitter change of the filtrate volume when the filtration equipment filters the wine filtrate; the equivalent characteristic of the filtration pressure represents the equivalent filtration pressure required to produce the same filtrate volume under specific filtration conditions.

[0028] In specific implementation, first, the filtrate volume curve is divided into multiple filtrate sub-segments. The filtrate volume curve can be divided according to the filter pressure range. For example, the filtrate volume curve can be segmented according to different filter pressure ranges to obtain multiple filtrate sub-segments; then, the filtrate volume change rate of each filtrate sub-segment is determined, that is, the overall slope of the filtrate sub-segment can be used as the filtrate volume change rate of the filtrate sub-segment, thereby obtaining the filtrate volume change rate of each filtrate sub-segment; secondly, the jitter of the filtrate volume when the filtration equipment filters the wine is determined by the filtrate volume change rate of all filtrate sub-segments, that is, the inverse of the standard deviation of the filtrate volume change rate of all filtrate sub-segments can be used as the jitter of the filtrate volume when the filtration equipment filters the wine; finally, the wine filtrate volume in the filtrate volume curve is calculated, that is, the mean of all wine filtrate volumes is used as the wine filtrate volume in the filtrate volume curve, so that the ratio of twice the wine filtrate volume in the filtrate volume curve to the jitter of the filtrate volume is used as the equivalent characteristic of the filter pressure when the filtration equipment filters the wine.

[0029] Preferably, in some embodiments, reference Figure 2 As shown in FIG. 1 , this figure is an exemplary flow chart for determining the viscosity characteristics of the filtrate in some embodiments of the present application. In this embodiment, the filtrate viscosity characteristics when the filtration device clarifies the wine filtrate using the jitter degree of the filtrate amount and the equivalent characteristics of the filtration pressure can be determined by the following steps: First, in step 1021, the filtrate mass fraction of the wine filtrate in the filtration device is obtained; Then, in step 1022, the filtrate viscosity when the filtration device clarifies the wine filtrate is determined using the equivalent characteristic of the filtration pressure and the filtrate mass fraction; Finally, in step 1023, the filtrate viscosity is characteristically corrected according to the jitter of the filtrate volume, so as to obtain the filtrate viscosity characteristic when the filtration device clarifies the wine filtrate.

[0030] It should be noted that, in the present application, the filtrate viscosity characteristic is a characteristic used to represent the viscosity of the wine filtrate after correction; the filtrate mass fraction represents the mass proportion of solid matter in the wine filtrate; in specific implementation, first, the filtrate mass fraction of the wine filtrate in the filtration equipment is measured and obtained, and a mass analyzer can be used to determine the solid content in the wine filtrate to determine the filtrate mass fraction of the wine filtrate; then, the filtrate viscosity of the wine filtrate clarified by the filtration equipment can be calculated using the equivalent characteristic of the filtration pressure and the filtrate mass fraction, that is, the ratio of the equivalent characteristic of twice the filtration pressure to the filtrate mass fraction is used as the filtrate viscosity when the filtration equipment clarifies the wine filtrate; finally, since jitter and instability may occur in the actual filtration process, the filtrate viscosity calculation needs to consider these factors for correction. In the present application, the jitter degree of the filtrate amount is used to correct the calculated filtrate viscosity, that is, the product of the filtrate viscosity and the jitter degree of the filtrate amount is used as the filtrate viscosity characteristic when the filtration equipment clarifies the wine filtrate.

[0031] In addition, it should be noted that generating a filtrate volume curve and extracting the jitter of the filtrate volume and the equivalent characteristics of the filter pressure can help reveal the dynamic changes in the filtration process. By using the jitter of the filtrate volume and the equivalent characteristics of the filter pressure to determine the filtrate viscosity characteristics, the filtration equipment can be controlled in real time. During the filtration process, different filtrate viscosities will lead to different filtration requirements. Adjusting the filter pressure to adapt to these requirements can improve the filtration efficiency.

[0032] In step 103, the filter mesh morphology characteristics of the filtering device are obtained, the osmotic compensation degree of the filtering device is determined by the jitter of the filtrate volume and the filter mesh morphology characteristics, and the filtrate flow characteristics of the filtering device when clarifying the wine filtrate are determined based on the filtrate viscosity characteristics and the osmotic compensation degree.

[0033] In specific implementation, image processing software can be used to analyze the microstructure of the filter and extract its morphological characteristic parameters, namely, the filter morphological characteristics of the filtering device; it should be noted that in the present application, the filter morphological characteristics include the filter porosity and filter area of ​​the filtering device, and the filter porosity represents the proportion of the pore area per unit area of ​​the filter device.

[0034] Preferably, in some embodiments, reference Figure 3 As shown in FIG. 1 , this figure is an exemplary flow chart for determining the permeability compensation degree in some embodiments of the present application. In this embodiment, the permeability compensation degree of the filtration device is determined by the jitter degree of the filtrate volume and the filter screen morphology characteristics, which can be achieved by the following steps: First, in step 1031, the porosity of the filter is extracted from the filter morphological characteristics; Then, in step 1032, the filtrate flow of the wine filtrate under the current filtration pressure condition is simulated using the jitter degree of the filtrate amount and the filter screen porosity to obtain the filtrate flow rate under the current filtration pressure condition; Secondly, in step 1033, the flow rate deviation of the wine filtrate is obtained by comparing the filtrate flow rate under the current filtration pressure condition with the actual filtrate flow rate; Finally, in step 1034, the degree of permeation compensation of the filtration device is determined based on the flow rate deviation of the wine filtrate.

[0035] It should be noted that, in the present application, the permeability compensation degree is an indicator used to correct the actual wine filtrate permeability changes caused by the filter morphology characteristics; the flow rate deviation represents the deviation value between the filtrate flow rate under the current filtration pressure conditions and the actual filtrate flow rate.

[0036] In specific implementation, first, the porosity of the filter can be extracted from the filter morphological characteristics; then, the flow simulation can be performed in combination with the jitter of the filtrate volume and the porosity of the filter, and the flow behavior of the wine filtrate under the current filter pressure conditions can be simulated by using a fluid mechanics model in combination with the porosity of the filter and the jitter of the filtrate volume. Based on the fluid mechanics model, the filtrate flow rate of the wine filtrate under the current filter pressure conditions is calculated, and the filtrate flow rate reflects the ideal flow state of the wine filtrate in the filter mesh of the filtration device in theory; secondly, the filtrate flow rate under the current filter pressure conditions is compared with the actual filtrate flow rate, that is, the absolute value of the difference between the filtrate flow rate under the current filter pressure conditions and the actual filtrate flow rate is calculated, and the result is used as the flow rate deviation of the wine filtrate; finally, the theoretical permeability coefficient is obtained, and the theoretical permeability coefficient represents the theoretical permeability of the filter mesh of the filtration device, so that the permeability compensation degree of the filtration device can be determined based on the flow rate deviation of the wine filtrate, that is, the ratio of the flow rate deviation of the wine filtrate to the actual filtrate flow rate is added by one, and the product of the result and the theoretical permeability coefficient is calculated, and the product result can be used as the permeability compensation degree of the filtration device.

[0037] Optionally, in some embodiments, the filtrate flow characteristics of the filtration device when clarifying the wine filtrate can be determined based on the filtrate viscosity characteristics and the osmotic compensation degree in the following manner, namely: Extracting the filter area from the filter morphological characteristics of the filtering equipment; Obtaining the filter pressure difference in the filter equipment; The filtrate flow characteristics of the filtration device when clarifying the wine filtrate are determined by the filter area, the filter pressure difference in the filtration device, the filtrate viscosity characteristics and the osmotic compensation degree.

[0038] In specific implementation, first, the filter area can be extracted from the filter morphology characteristics of the filtering device; then, the filter pressure difference in the filtering device can be obtained, that is, the difference between the filter pressure in the filtering device and the external air pressure is calculated, and the difference is used as the filter pressure difference in the filtering device; finally, the filtrate flow characteristic of the filtering device when clarifying the wine filtrate can be determined by the filter area, the filter pressure difference in the filtering device, the filtrate viscosity characteristics and the osmotic compensation degree. The filtrate flow characteristic is a characteristic of the filtrate flow of the filtering device when clarifying the wine filtrate. The filtrate flow characteristic can be achieved in the following way: filtrate flow characteristic = filter area * filter pressure difference in the filtering device * osmotic compensation degree / filtrate viscosity characteristic.

[0039] It should be noted that by obtaining the morphological characteristics of the filter, the flow of wine filtrate in the filtration equipment can be accurately simulated, which helps to identify and solve potential filtration bottlenecks or blockage problems, thereby improving filtration efficiency. During the filtration process, the viscosity and flow rate of the wine filtrate may fluctuate with changes in operating conditions. By combining the real-time collected filtrate viscosity characteristics and filtrate flow characteristics, the filtration equipment can quickly respond to these changes, automatically adjust the filtration pressure and filtrate flow rate, and ensure that the filtration process is always in the best state.

[0040] In step 104, a filter pressure control signal of the filter device is generated based on the filtrate viscosity characteristics and the filtrate flow characteristics, and the filter pressure of the filter device when clarifying the wine filtrate is regulated by the filter pressure control signal.

[0041] Optionally, in some embodiments, the filter pressure control signal of the filter device is generated based on the filtrate viscosity characteristics and the filtrate flow characteristics in the following manner, namely: Determining the filtrate jitter amount under the current filtration pressure condition based on the filtrate flow characteristics; Using the filtrate shaking amount, determining a filtration pressure adjustment amount when the filtration device clarifies the wine filtrate under current filtration pressure conditions; The filter pressure adjustment amount is corrected according to the filtrate viscosity characteristics to obtain the filter pressure control amount; A filter pressure control signal of the filter device is generated according to the filter pressure regulation amount.

[0042] In specific implementation, first, the filtrate jitter amount under the current filter pressure condition can be determined based on the filtrate flow characteristic, that is, the deviation value between the theoretical filtrate flow and the filtrate flow characteristic is calculated, and the deviation is used as the filtrate jitter amount under the current filter pressure condition, and the filtrate jitter amount represents the flow fluctuation amount of the wine filtrate; then, a mathematical model between the filtrate jitter amount and the filter pressure is obtained. The mathematical model is based on previous operating data and reflects the relationship between the filtrate jitter amount and the filter pressure. Therefore, the mathematical model can be used to calculate the required filter pressure adjustment amount in combination with the currently obtained filtrate jitter amount. Generally, the larger the jitter amount, the larger the filter pressure adjustment amount is, so as to reduce the instability caused by the jitter; secondly, the filtrate viscosity characteristic is used to correct the filter pressure adjustment amount to obtain the filter pressure control amount. The larger the filtrate viscosity characteristic is, the larger the filter pressure adjustment amount is. The larger the filter pressure is, the greater the filtrate flow resistance is. Therefore, the filter pressure adjustment amount may require a higher correction value. The filter pressure control amount can be determined according to the following method: filter pressure control amount = filter pressure adjustment amount * (1 + permeability compensation (filtrate viscosity characteristics - reference filtrate viscosity)); finally, a filter pressure control signal for the filtration device is generated according to the filter pressure control amount. The filter pressure control signal can be directly transmitted to the control system of the filtration device for real-time adjustment of the working filter pressure of the device. In order to convert the filter pressure control amount into a specific filter pressure control signal, a control model can be established. The control model maps the filter pressure control amount to a filter pressure control signal according to the specific characteristics of the filtration device (such as response time, maximum pressure range, etc.). For example, the filter pressure control amount can be mapped to a filter pressure control signal through a linear control model.

[0043] Optionally, in some embodiments, the filtration pressure of the filtration device when clarifying the wine filtrate can be regulated by the filtration pressure control signal in the following manner, namely: transmitting the filter pressure control signal to a control system of the filter device; The control system of the filtering device adjusts the pressure regulating device according to the filtering pressure control signal to complete the filtering pressure regulation when the filtering device clarifies the wine filtrate.

[0044] In specific implementation, first, the generated filter pressure control signal can be transmitted to the control system of the filtration equipment. The signal transmission can be completed through analog signals, voltage, current, digital signals, etc., which will not be repeated here; then, the control system automatically adjusts the pressure regulating device inside the equipment according to the received filter pressure control signal, such as a hydraulic valve, an electric regulating valve or a pump speed controller. For example, the control system will adjust the opening of the valve according to the filter pressure control signal to increase or decrease the amount of filtrate passing through, thereby changing the pressure inside the filtration equipment to achieve filter pressure regulation when the filtration equipment clarifies the wine filtrate.

[0045] It should be noted that by precisely controlling the filtration pressure, the stable performance of the filtration equipment can be maintained, and by adjusting the filtration pressure in real time, the uneven filtrate quality caused by pressure fluctuations during the filtration process can be reduced.

[0046] It can be seen that in the present application, the filter pressure of the filtration equipment can be controlled in real time according to the viscosity characteristics and flow characteristics of the wine filtrate; wherein, by generating a filtrate volume curve and extracting the jitter of the filtrate volume and the equivalent characteristics of the filter pressure, it is helpful to reveal the dynamic changes in the filtration process. During the filtration process, different filtrate viscosities will lead to different filtration requirements. Adjusting the filter pressure to adapt to these requirements can improve the filtration efficiency; then, by obtaining the morphological characteristics of the filter, the flow of the wine filtrate in the filtration equipment can be accurately simulated, which helps to identify and solve potential filtration bottlenecks or blockage problems, thereby improving the filtration efficiency. During the filtration process, the viscosity and flow of the wine filtrate may fluctuate with changes in operating conditions; finally, by combining the filtrate viscosity characteristics and filtrate flow characteristics collected in real time, the filtration equipment can respond quickly to these changes and automatically adjust the filter pressure and filtrate flow. By accurately controlling the filter pressure, the stable performance of the filtration equipment can be maintained, and by adjusting the filter pressure in real time, the uneven filtrate quality caused by pressure fluctuations during the filtration process can be reduced. In summary, the technical solution adopted in the present application can adjust the filtration pressure of the filtration equipment in real time according to the viscosity characteristics and flow characteristics of the wine filtrate, so as to maintain the stable filtration performance of the filtration equipment.
