Detailed Description
In order to solve the problems of quality degradation and cross contamination risk of concentrated products caused by a large amount of foam pumped by vacuum equipment in the material concentration process in the related art, embodiments of the present application provide a material concentration control system, a method, a device, an electronic device and a storage medium.
The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are for illustration and explanation only, and are not intended to limit the present application, and embodiments and features of embodiments of the present application may be combined with each other without conflict.
Generally, liquid materials evaporate quickly in a boiling state, and the boiling point of the materials changes with pressure, for example, the pressure increases, the boiling point increases, and the pressure decreases with small boiling point. Taking milk as an example, the boiling point of milk is 100 ℃ at 101kPa, and the boiling point is only 45-55 ℃ at the vacuum degree of 82.7-90.6 KPa. The material is concentrated at a lower temperature, the material is not affected by high temperature, the damage and loss of heat unstable components can be avoided, and the nutritional components and the aroma of the material can be better maintained. In particular, certain amino acids, flavonoids, phenols, vitamins and the like can be prevented from being damaged by heating. And some materials with relatively high viscosity such as sugar, protein, pectin, mucilage and the like can be prevented from being coked by low-temperature concentration. Therefore, the vacuum concentration technology is widely applied to the industries of pharmacy, food and beverage, dairy product preparation and the like.
Firstly, it should be noted that the materials in the embodiments of the present application are liquid materials such as liquid medicine, alcohol solution, milk, juice stock solution, fermentation liquid, etc. Moreover, the concentration control system provided by the embodiment of the application can be suitable for all liquid material concentration scenes needing foam control.
Fig. 1 is a schematic structural diagram of a material concentration control system provided in an embodiment of the present application, including a concentration chamber, a detection device and a control device, where:
the detection device, such as a computer, can acquire an image of the liquid material in the concentration chamber through the built-in camera or the external camera, and can determine the concentration state of the material based on the concentration state characterization information of the material in the image when the foam amount in the concentration chamber exceeds a set amount based on the image, so as to send indication information corresponding to the concentration state to the control device, wherein the concentration state characterization information at least comprises foam distribution information;
the control device, such as a programmable logic controller (Programmable Logic Controller, PLC), can adjust the temperature and/or the vacuum degree in the concentration chamber based on the indication information corresponding to the concentration state so as to control the foam amount in the concentration chamber, thereby achieving the purpose of defoaming.
In some embodiments, the material concentration control system may adjust the temperature and/or vacuum of the material based solely on the foam distribution information.
For example, the detection device is specifically configured to determine that the concentration state of the material is a concentration state in which the concentration speed exceeds a first speed threshold if the foam distribution information determines that the foam is full of the liquid phase interface of the material and the foam height exceeds the set height but does not exceed an upper height limit, and then send indication information corresponding to the concentration speed exceeding the first speed threshold to the control device, where the upper height limit is higher than the set height;
the control device is specifically used for reducing the vacuum degree in the concentration chamber and reducing the temperature in the concentration chamber if the received indication information indicates that the concentration speed of the material exceeds the first speed threshold.
For another example, the detection device is specifically configured to determine that the concentrated state of the material is a material running risk if the foam is full of the liquid phase interface of the material and the foam height exceeds the upper height limit based on the foam distribution information, and then send indication information corresponding to the material running risk to the control device;
and the control device is specifically used for stopping inputting steam into the concentration chamber and reducing the vacuum degree in the concentration chamber if the received indication information indicates that the material has a material running risk.
In some embodiments, the concentration state characterization information further includes temperature distribution information of the material, and the concentration control system of the material may adjust the temperature and/or vacuum of the material based on the foam distribution information and the temperature distribution information of the material to achieve the defoaming purpose.
For example, the detection device is specifically configured to determine that, if foam is distributed in a central area of a liquid phase interface of the material based on foam distribution information, coverage rate of the liquid phase interface of the material is within a set interval, and if temperature distribution of the material is determined to be uniform based on temperature distribution information, determine that a concentration state of the material is that a concentration speed exceeds a second speed threshold, where the central area of the liquid phase interface is within a preset distance range from a center of the liquid phase interface, an upper limit of the set interval is a fraction (i.e., the foam is not fully distributed in the liquid phase interface), and the second speed threshold is smaller than the first speed threshold.
The control device is specifically used for determining to reduce the temperature in the concentration chamber if the received indication information indicates that the concentration speed of the material exceeds the second speed threshold.
The detection device is also used for judging that the concentration state of the material is stable if the foam distribution information is used for determining that the foam is distributed in the central area of the liquid phase interface of the material, the coverage rate of the liquid phase interface of the material is lower than a set value such as 30%, and the temperature distribution information is used for determining that the temperature distribution of the material is uniform;
And the control device is also used for keeping the current temperature and vacuum degree in the concentration chamber if the indication information indicates that the concentration state of the material is stable.
Therefore, when the material concentration state is stable, a certain amount of foam is allowed to exist in the concentration chamber, repeated defoaming is not needed, and the control strategy is more reasonable.
In addition, in this case, the detecting device is further configured to determine that the material is not smooth in circulation and the concentration state of the material is abnormal if the foam distribution information is based on the foam distribution information to determine that the foam is distributed in the central area of the liquid phase interface of the material, and the local temperature of the central area of the liquid phase interface of the material is determined to exceed the upper temperature limit based on the temperature distribution information, and then send alarm information indicating that the concentration state is abnormal to the control device;
and the control device is also used for carrying out alarm processing based on the alarm information so that staff can process in time.
Therefore, the circulation condition of the materials can be automatically judged, and the warning is timely given when the circulation of the materials is not smooth, so that the user experience is good.
In addition, the detection device is also used for comparing the height of the materials in the image with a preset height range and sending a comparison result to the control device if the foam amount in the concentration chamber is determined to not exceed the preset amount based on the image;
Generally, the preset height range includes a lowest liquid level threshold and a highest liquid level threshold, if the height of the material is lower than the lowest liquid level threshold, a comparison result lower than the lowest liquid level threshold is sent to the control device, and if the height of the material is higher than the highest liquid level threshold, a comparison result higher than the highest liquid level threshold is sent to the control device.
And the control device is also used for controlling feeding or stopping feeding based on the comparison result.
For example, if a comparison of the minimum level threshold is received, controlling the feed; if a comparison result is received which is higher than the highest liquid level threshold value, the control stops feeding.
Therefore, the height of the material is determined by means of the image, and feeding is automatically controlled or stopped based on the height of the material, so that material overrun material running and low-limit empty burning coking can be prevented, and stable quality of the concentrated product and introduction of abnormal impurities can be guaranteed.
In addition, when the feeding amount of the material reaches the upper feeding limit, the detection device is further used for sending concentration stopping information to the control device if the volume of the material is determined to be reduced to the set volume based on the image;
and the control device is also used for stopping concentrating the material in response to the concentration stopping information.
Therefore, automatic judgment of the concentration end point is realized by means of the image, manual confirmation action is assisted, the condition that an operator repeatedly starts and stops to observe the volume and the density of materials to determine the concentration end point can be avoided, the labor cost can be saved, and the technical threshold of the concentration station operator can be reduced. In addition, the operation efficiency of the concentration process can be improved, and the uniform stability of the product quality in the concentration process can be ensured.

The following describes a material concentration process with reference to fig. 2, and fig. 3 is a flowchart of a material concentration process according to an embodiment of the present application, including the following steps:
step one, opening a vacuum regulating valve
Vacuum is drawn in the concentrating chamber (5).
Step two, opening a circulating water inlet valve of the condenser, and passing through a water inlet of the condenser

Condensed water is led through.
And thirdly, after the vacuum degree in the concentrating chamber (5) reaches the set vacuum degree, opening a feed valve at the bottom of the heating chamber (3), enabling materials to enter the heating chamber (3) from the material feed inlet (1), and enabling the materials to enter the concentrating chamber (5) through a pipeline at the bottom of the heating chamber (3).
And step four, an industrial visible light and thermal imaging two-in-one camera collects images in the concentrating chamber (5) through the quartz glass sight glass (6) and sends the collected images to the detection device. When the detection device determines that the foam amount in the concentration chamber (5) does not exceed the set amount based on the image, if the detection device determines that the height of the material in the concentration chamber (5) reaches the upper feeding limit liquid level in the concentration chamber (5) based on the image, the detection device determines to stop feeding, outputs a control signal to a control device such as a PLC, and controls the PLC to close a feeding valve so as to stop feeding.
Step five, opening a steam regulating valve

At this stage, there are several failure determination scenarios: 1) If the temperature of the material does not change after the steam opening time exceeds the set time, judging the steam fault, and further sending out alarm prompt information of the steam fault; 2) After the steam is turned on, the temperature of the material is in a local overheat state for a long time, the jet orifice of the heating chamber (3) is free from material jet, and the material is free from rotation, so that the heating chamber (3) is judged to be blocked, namely, the circulation of the material is unsmooth, the concentration state of the material is abnormal, and further, alarm prompt information of the blocking of the heating chamber can be sent out.
And step six, fluid infusion control. In the concentration process, if the detection device determines that the foam amount in the concentration chamber (5) does not exceed the set amount based on the image acquired by the industrial visible light and thermal imaging two-in-one camera in real time, the height of the material in the image can be acquired. When the height of the material is lower than the lower limit liquid level, outputting an indication signal lower than the lower limit liquid level to the PLC, and controlling the feed valve to be opened by the PLC to automatically feed; when the height of the material is higher than the upper limit liquid level, outputting a liquid level indicating signal higher than the upper limit to the PLC, and controlling the feed valve to be closed by the PLC so as to stop feeding.
And step seven, defoaming control. In the concentration process, if the detection device determines that the foam amount in the concentration chamber (5) exceeds the set amount based on the images acquired by the industrial visible light and thermal imaging two-in-one camera in real time, the detection device triggers a defoaming function and outputs a control signal to the PLC, and the PLC adjusts the temperature and/or the vacuum degree in the concentration chamber (5) so as to control the concentration state of the materials, thereby achieving the purpose of controlling the foam.

And step three, the foam occupies the whole indoor cross section, the foam height is higher than the liquid inlet upper limit liquid level by a certain distance (corresponding to the set height) but not exceeds the foam upper limit liquid level (corresponding to the height upper limit), the detection device judges that the concentration state of the material is faster (corresponding to the concentration speed exceeding a first speed threshold), an indication signal corresponding to the faster state is sent to the PLC, and when the received indication signal indicates that the concentration of the material is faster, the PLC properly reduces the opening of the steam regulating valve and can open the concentration chamber emptying regulating valve (8) to properly reduce the vacuum degree in the concentration chamber (5), so that the foam is eliminated.
Step four, the foam occupies all indoor cross sections, the foam height is higher than the foam upper limit liquid level, the detection device judges that the material concentration state is in a material running risk, an indication signal corresponding to the material running risk is sent to the PLC, and the PLC can close the steam regulating valve when the received indication signal indicates that the material has the material running risk

And fifthly, the foam occupies a liquid phase center area of the material, the local temperature of the liquid phase center area of the material is overheated (namely, the temperature exceeds the upper temperature limit), the detection device judges that the concentration state of the material is abnormal, and sends alarm information to the PLC, so that the PLC prompts a worker to check the reason and remove the fault.
And step eight, concentrating and collecting the paste. After the liquid supplementing amount of the material reaches the upper limit of the feeding, concentrating and entering a paste collecting stage, wherein the detection device is based on industrial visible light and thermal imagingThe real-time collected image of a camera confirms that the volume of the material in the concentrating chamber (5) is reduced to the paste collecting volume (namely the set volume), then a control signal for stopping concentration is sent to the PLC, the PLC prompts the staff to judge whether to collect the paste, and after receiving the information for confirming the paste collection, the steam regulating valve is controlled to be closed
