Detailed Description
The present application is described in further detail below in conjunction with figures 1-4.
The embodiment of the application discloses an intelligent control method for a continuous low-temperature concentration device of red sage root, as shown in fig. 1, the method is applied to the low-temperature concentration device, and the low-temperature concentration device comprises a dilution unit for adding purified water into the low-temperature concentration device, a liquid level detection unit for detecting the liquid level height in the low-temperature concentration device, an ethanol detection unit for detecting the ethanol content in the red sage root concentrated solution steam, a stirring unit for stirring the red sage root concentrated solution steam, a heating unit for heating the red sage root extract and a temperature detection unit for detecting the temperature of the red sage root extract; the liquid level detection unit can be a liquid level sensor; the ethanol detection unit can be an ethanol detector or a conductivity measuring instrument, the conductivity measuring instrument can measure the conductivity of the concentrated salvia miltiorrhiza concentrated solution steam after concentration, and then the concentration of ethanol is correspondingly obtained through the conductivity; the stirring unit can be a driving motor and stirring blades, and the driving motor can drive the stirring blades to rotate so as to stir the gas; the temperature rising unit can be the temperature rising unit of the low-temperature concentration device; the temperature detection unit may be a temperature sensor.
As shown in fig. 2, the method comprises the steps of:
s10, when the low-temperature concentration device is started, the liquid level detection unit is controlled to detect and acquire a liquid level value in real time.
Specifically, after the red sage root extracting solution to be concentrated is added into the low-temperature concentration device, the user can start the low-temperature concentration device by pressing a start button of the low-temperature concentration device; when the low-temperature concentration device is started, the liquid level detection unit is controlled to detect and acquire the liquid level value of the red sage root extracting solution in the low-temperature concentration device in real time.
S20, calculating the capacity of the red sage root in the low-temperature concentration device according to the liquid level value.
Specifically, the low-temperature concentration device calculates the volume of the red sage root in the low-temperature concentration device in real time according to the liquid level value when acquiring the liquid level value of the red sage root extracting solution; because the container for containing the red sage root extracting solution is a fixed volume, the liquid level of the red sage root extracting solution and the height of the red sage root extracting solution have a one-to-one correspondence, so that the low temperature concentrating device can calculate the red sage root capacity in the concentrating device according to the liquid level value of the red sage root extracting solution.
And S30, controlling the ethanol detection unit to detect and acquire the ethanol content when the salvia miltiorrhiza capacity reaches the preset concentration capacity.
Specifically, when the low-temperature concentration device detects that the salvia miltiorrhiza capacity is concentrated to a preset concentration capacity, firstly controlling a detection unit to detect the ethanol content in the salvia miltiorrhiza concentrated solution steam; comparing the detected ethanol content with a preset standard value; the predetermined standard value is the ethanol content in the absence of ethanol taste in the vapor, i.e., the ethanol content is less than 5%.
S40, if the ethanol content is not lower than a preset standard value, controlling the dilution unit to add purified water with a preset capacity into the low-temperature concentration device;
specifically, if the ethanol content is not lower than the preset standard value, the low-temperature concentration device judges that the concentration of the salvia miltiorrhiza extracting solution does not reach the standard, then the diluting unit is controlled to add purified water with a preset volume into the low-temperature concentration device, and at the moment, the salvia miltiorrhiza volume in the low-temperature concentration device is larger than the preset concentration volume due to the addition of the purified water, so that the low-temperature concentration device can continuously concentrate the salvia miltiorrhiza extracting solution; meanwhile, if the ethanol content in the vapor of the red sage root concentrated solution still does not reach the standard after the purified water is added for concentration again, the low-temperature concentration device can control the dilution unit to add the purified water with the preset capacity into the low-temperature concentration device again until the ethanol content reaches the standard, namely the ethanol content is lower than the preset standard value.
And S50, if the ethanol content is lower than a preset standard value, judging that the concentration is finished and outputting prompt information related to the concentration.
Specifically, if the ethanol content is lower than a preset standard value, the low-temperature concentration device judges that the concentration of the salvia miltiorrhiza extracting solution is finished, and then outputs relevant prompt information about the completion of the concentration so as to remind a user that the concentration is finished. The low-temperature concentration device can automatically complete repeated concentration of the red sage root extracting solution after the red sage root extracting solution to be concentrated is added into the low-temperature concentration device by a user until the ethanol content in the red sage root extracting solution steam reaches the standard; that is, the low-temperature concentration device can automatically concentrate the red sage root extracting solution, thereby improving the intelligentization degree of the red sage root extracting solution concentration process.
In one embodiment, consider that if the concentration of the red sage root extract first added into the low-temperature concentration device by the user is lower than the preset concentration capacity, the red sage root extract always cannot meet the trigger condition that the red sage root capacity reaches the preset concentration capacity, and then the red sage root extract is excessively concentrated; in order to further improve the concentration effect of the red sage root extract; after the low-temperature concentration device calculates the volume of the red sage root in the low-temperature concentration device according to the liquid level value, the following steps can be continuously executed:
the low-temperature concentration device compares the capacity of the red sage root with the preset concentration capacity; namely, the initial adding amount of the red sage root extract is compared with the preset concentration capacity; if the capacity of the red sage root is larger than the preset concentration capacity, judging that the initial addition amount of the red sage root extract is normal, and then continuously concentrating the red sage root extract by the low-temperature concentration device; if the red sage root capacity is not greater than the concentration capacity, judging that the initial addition amount of the red sage root extracting solution is insufficient, stopping concentrating by shutting down the low-temperature concentrating device at the moment, and sending relevant reminding information about the insufficient red sage root capacity to the user terminal so as to remind the user terminal to continuously add the red sage root concentrated solution or reset the concentration capacity; the user terminal can be intelligent equipment such as a mobile phone or a computer and is in communication connection with the low-temperature concentration device; the low-temperature concentration device can automatically identify the abnormal condition that the initial addition amount of the red sage root extracting solution is insufficient, and prompt a user to treat the abnormal condition in time, so that the possibility of excessive concentration of the red sage root extracting solution caused by insufficient initial capacity is reduced, and the concentration effect of the red sage root extracting solution is further improved.
In one embodiment, when the ethanol detection unit detects the ethanol content in the salvia miltiorrhiza concentrate steam, there may be a case that the detection result of the ethanol detection unit has deviation due to uneven distribution of the ethanol in the salvia miltiorrhiza concentrate steam; in order to improve the accuracy of the detection result of the ethanol detection unit, the step of controlling the ethanol detection unit to detect and obtain the ethanol content by the low-temperature concentration device may be specifically performed as:
when the capacity of the red sage root reaches the preset concentration capacity, the low-temperature concentration device firstly controls the stirring unit to start for a preset time to stir the red sage root concentrated solution steam so that the ethanol can be uniformly distributed in the red sage root concentrated solution steam; when the stirring unit stops stirring, controlling the ethanol detection unit to detect the ethanol content in the steam of the salvia miltiorrhiza concentrated solution; the possibility of deviation of the detection result of the ethanol detection unit due to uneven distribution of ethanol in the vapor of the salvia miltiorrhiza bunge concentrate is reduced, and the accuracy of the detection result of the ethanol detection unit is improved.
In one embodiment, in order to achieve a prediction of the concentration process of the red sage root extract; after the cryoconcentration device controls the dilution unit to add a predetermined volume of purified water to the cryoconcentration device, the following steps may be further performed:
starting the low-temperature concentration device to time and record the concentration time consumed by the red sage root volume reaching the preset concentration volume again, namely the time consumed from the completion of adding purified water to the reduction of the red sage root volume to the concentration volume again, and setting the recorded concentration time as standard time; then the low-temperature concentration device calculates a first difference value between the ethanol content and a preset standard value, if the first difference value is smaller than a preset trigger value, the first difference value indicates that the current ethanol content is close to a scalar, namely, after concentration is performed again, the ethanol content in the salvia miltiorrhiza concentrated solution steam is up to the standard with high probability; starting timing and generating accumulated time, and sending reminding information related to the fact that the concentration of the red sage root is about to finish to a user terminal when the difference between the accumulated time and the standard time reaches a preset reminding value, so that a user can collect the concentrated red sage root extracting solution in time; if the first difference value is not smaller than the preset trigger value, judging that the ethanol content of the salvia miltiorrhiza concentrated solution still cannot reach the standard after the next concentration, and then continuing to concentrate the salvia miltiorrhiza extracting solution normally. The low-temperature concentration device can predict the concentration progress of the red sage root extracting solution and inform a user in advance before the concentration is about to be completed, thereby further improving the intelligent degree of the concentration process of the red sage root extracting solution.
In one embodiment, consider that if the dilution unit adds purified water into the low-temperature concentration device multiple times during the concentration process of the radix salviae miltiorrhizae, that is, if the concentration process of the radix salviae miltiorrhizae is circulated multiple times, the concentration time recorded by the low-temperature concentration device is not unique; in order to further improve the effect of the cryoconcentration apparatus on the prediction of the concentration schedule of the red sage root extract, the step of the cryoconcentration apparatus setting the concentration time to the standard time may be specifically performed as:
if the concentration time is unique, namely, after the dilution unit adds purified water into the low-temperature concentration device only once, the first difference value between the ethanol content in the salvia miltiorrhiza concentrated steam reaching the concentration capacity and the preset standard value is smaller than the preset trigger value; directly setting the unique concentration time as a standard time; if the concentration time is not unique, namely the dilution unit adds purified water into the low-temperature concentration device for a plurality of times, a plurality of concentration times can occur at the moment; the last recorded concentration time is set as the standard time, so that the difference between the standard time and the time required for the last concentration is further reduced, and the prediction effect of the low-temperature concentration device on the concentration progress of the red sage root extract is further improved.
In one embodiment, in order to further improve the accuracy of the low-temperature concentration device in predicting the concentration progress of the radix salviae miltiorrhizae; the step of the cryoconcentration device sending a reminder associated with the imminent end of concentration of the root of red-rooted salvia to the user terminal may be specifically performed as:
when the difference between the accumulated time and the standard time reaches a preset reminding value, the low-temperature concentration device controls the ethanol detection unit again to detect and acquire the ethanol content, then calculates a second difference between the ethanol content and a preset standard value, and if the second difference is smaller than a preset approach value, namely the current ethanol content reaches the standard or the difference between the current ethanol content and the standard distance is small, judges that the ethanol content can reach the standard state when the accumulated time reaches the standard time, and then sends reminding information related to the fact that the concentration of the red sage root is about to finish to a user terminal; otherwise, canceling sending the reminding information related to the ending of the concentration of the red sage root to the user terminal; therefore, the possibility of false alarm of the low-temperature concentration device is reduced, and the accuracy of the low-temperature concentration device in predicting the concentration progress of the salvia miltiorrhiza is further improved.
In one embodiment, to further improve the intelligentization degree of the cryoconcentration device, the intelligent control method for the continuous cryoconcentration device for salvia miltiorrhiza can further comprise the following steps:
when the low-temperature concentration device is started to concentrate the red sage root extracting solution, controlling the temperature detection unit to detect the temperature of the red sage root extracting solution in real time and obtain a temperature detection value, then comparing the detected temperature detection value with a preset reasonable temperature range, and if the temperature detection value is smaller than the preset reasonable temperature range, namely the concentration temperature is lower, starting the temperature raising unit to heat the red sage root extracting solution until the temperature detection value reaches a preset standard temperature value, wherein the standard temperature value is positioned in the reasonable temperature range; if the temperature detection value is larger than a reasonable temperature range, namely the temperature of the red sage root extracting solution is too high, the temperature raising unit is controlled to close and utilize the temperature difference between the red sage root extracting solution and the external environment to cool; thereby achieving the effect of automatically controlling the temperature of the red sage root extracting solution and further improving the intelligent degree of the low-temperature concentration device.
It should be noted that, the concentration environment of the red sage root extract generally needs to be maintained at 50-75 ℃, i.e. the preset reasonable temperature range can be set at 50-75 ℃; when the temperature detection value is larger than the reasonable temperature range, the temperature of the red sage root extracting solution is higher than 75 ℃ and the external environment temperature is obviously lower than 75 ℃, so that the temperature of the red sage root extracting solution can be reduced by utilizing the temperature difference between the red sage root extracting solution and the external environment in a mode of closing the temperature rising unit.
