Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure. While the invention will be described in conjunction with the preferred embodiments, it is not intended that features of the invention be limited to these embodiments. On the contrary, the invention is described in connection with the embodiments for the purpose of covering alternatives or modifications that may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Moreover, some of the specific details have been left out of the description in order to avoid obscuring or obscuring the focus of the present invention. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
It should be noted that in this specification, like reference numerals and letters refer to like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.
The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
At present, as shown in fig. 1, a cut stem processing process may sequentially include a plurality of processes including drying, air separation, flavoring, and cut stem storage, but only a part of the processes (for example, the stages of cut stem flavoring and cut stem storage) has environmental temperature and humidity guarantee, and the processes like cut stem drying and cut stem air separation have no environmental temperature and humidity guarantee, and the moisture variation of these process points without temperature and humidity guarantee changes along with the change of the environmental temperature and humidity.
The stem wind is taken as an example, the dried stem is sent to a winnowing box through a vibrating conveyor, the qualified stem is floated by airflow from the bottom and then is conveyed to a stem perfuming room through a stem wind-separating square pipe, and certain moisture content loss (namely moisture variation before and after wind separation) exists in the stem under the airflow effect of air in a main workshop due to the effect of a negative pressure fan in the conveying process.
Based on the phenomenon, the inventor considers that the cut stem drying is taken as the last process of cut stem moisture control, and whether the set target value of the outlet moisture and the moisture change under the current environmental temperature and humidity conditions are suitable or not can directly influence the final moisture of the finished cut stems. Therefore, a method based on the setting of the moisture value of the cut rolled stem drying outlet so as to make the moisture content of the finished cut rolled stems meet the standard has been proposed.
As shown in fig. 2, the present invention provides a method for controlling moisture at a cut stem drying outlet, comprising the following steps:
step S1: and establishing a prediction model representing the relation between the moisture variation of the cut stems before and after the wind separation and the humidity of the workshop.
Optionally, step S1 may specifically include the following steps:
step S11: obtaining historical production data of a plurality of batches of cut stems at a threshold workshop temperature, wherein the historical production data comprises: moisture of cut stems before wind separation, moisture of cut stems after wind separation and workshop humidity.
Step S12: and establishing a prediction model according to the historical production data of the cut stems in each batch.
Theoretically, since the moisture variation of the cut stems before and after the air separation is respectively influenced by the ambient temperature and the ambient humidity of the production workshop, the relation between the moisture variation of the cut stems before and after the air separation and the temperature and the humidity of the workshop should be considered, however, the applicant finds that in the actual production, the temperature variation has little influence on the moisture variation of the cut stems before and after the air separation within a certain workshop temperature range (specifically, 25 ℃ to 35 ℃). Therefore, in order to further simplify the calculation process, in some embodiments of the present invention, only the relationship between the moisture change amount of the cut stems before and after the air classification and the plant humidity is considered. Alternatively, the workshop humidity can be the humidity at the air separation inlet of the cut stems, and the moisture of the cut stems before air separation can be the moisture at the drying outlet of the cut stems after the drying process because the cut stems are sent to the air separation box for air separation after being dried.
That is, for the processing process of each batch of cut stems, respectively collecting and recording the ambient humidity at the cut stem wind-separating inlet, the moisture at the drying outlet of the cut stems after the drying process and the moisture at the cut stems after the wind-separating process, and calculating the moisture variation of each batch of cut stems before and after the wind-separating according to the moisture at the drying outlet and the moisture at the cut stems after the wind-separating, namely:
moisture variation of cut stems before and after air separation, namely moisture at dry outlet-moisture of cut stems after air separation
According to the moisture variation of the cut stems before and after the corresponding wind separation of each batch and the corresponding environment humidity, simulating the prediction model by adopting linear regression analysis, wherein the method specifically comprises the following steps:
moisture variation of cut stems before and after the wind separation is 4.430-0.06261 (workshop humidity 100)
Wherein the unit of the moisture variation of the cut stems before and after the wind separation is percent.
Step S2: obtaining target moisture after the pneumatic separation of the cut stems according to partial process moisture of the qualified finished cut stems, wherein the partial process moisture comprises the following steps: final moisture, moisture after flavoring the cut stems and moisture after air separating the cut stems.
Specifically, step S2 may include the steps of:
acquiring the final moisture of qualified finished cut stems in a plurality of batches and the moisture of the cut stems after flavoring and the moisture of the cut stems after air separation in the production process;
and obtaining the target moisture after the pneumatic separation of the cut stems according to the final moisture of the qualified finished cut stems in each batch, the moisture after the flavoring of the cut stems and the moisture after the pneumatic separation of the cut stems.
Specifically, referring to fig. 1, the cut stems are subjected to subsequent flavoring and cut stem storage processes after being subjected to air classification, and the finished cut stems are finally obtained, as described above, the flavoring process and the cut stem storage process have environmental temperature and humidity guarantee, so that in the process, the difference of the moisture variation quantity among the cut stems of each batch is not large, and in the conveying process of conveying the cut stems to the flavoring room through the cut stem air classification square tube after being subjected to air classification, the cut stems are not influenced by the environment due to no temperature and humidity guarantee.
Specifically, the calculation formula of the target moisture f after the cut stem is subjected to wind separation is as follows:
wherein f represents the target moisture content after the stem shreds are subjected to wind separation, a i 、b i 、c i Respectively representing the final moisture of the i-th batch of qualified finished cut stems, the moisture of the flavored cut stems and the moisture of the air-separated cut stems, and n represents the total quantity of the batches of qualified finished cut stems.
Step S3: and obtaining the target moisture of the cut stem drying outlet under the humidity of the target workshop according to the target moisture after the cut stems are subjected to wind separation and the prediction model.
According to the invention, the prediction relation between the moisture variation of the cut stems before and after the air separation and the workshop humidity is established, the target moisture of the cut stem drying outlet which is actually required is accurately obtained by utilizing the target moisture after the air separation of the cut stems on the basis of the prediction relation, and then the target value of the moisture of the cut stem drying outlet is set during the drying process, so that the moisture content of the finished cut stems obtained by the subsequent process can meet the standard, the problem of moisture off-standard of the finished cut stems caused by inconsistent moisture variation in the cut stem processing process due to environmental humidity variation caused by variation of seasons, climates, weather and the like is effectively solved, the target value of the moisture of the cut stem drying outlet can be accurately set from heat, and the requirement of the standard conformity of the moisture of the finished cut stems is met.
Alternatively, in some embodiments of the present invention, step S3 may include:
acquiring moisture variation of the cut stems before and after the wind separation respectively corresponding to different workshop humidities based on a prediction model;
acquiring a stem shred drying outlet moisture calculation model according to stem shred moisture variation before and after the air separation corresponding to the target moisture after the stem shred air separation and different workshop humidities respectively;
and substituting the target workshop humidity into the stem shred drying outlet moisture calculation model to obtain the target stem shred drying outlet moisture.
Firstly, according to the environmental humidity of the actual production workshop, the water content variation g before and after the wind separation under different humidity conditions is calculated by combining the prediction model j (ii) a And according to the determined target moisture f after the stem shreds are subjected to air separation and the moisture variation g before and after the air separation corresponding to each humidity respectively j Obtaining the target moisture h of the stem drying outlet corresponding to the humidity of each workshop j . In particular, h j ＝f+g j . Then, before production starts, the target value of the moisture of the cut stem drying outlet corresponding to the ambient humidity can be automatically searched according to the obtained target moisture of the cut stem drying outlet corresponding to the ambient humidity of each workshop according to the values of the ambient temperature and the ambient humidity of the actual production workshop, and production is carried out after setting, so that the finished cut stems are ensured to meet the process standard.
Optionally, in some other embodiments of the present invention, step S3 may include:
substituting the target workshop humidity into the prediction model to obtain the moisture variation of the cut stems before and after the target wind score corresponding to the target workshop humidity;
and calculating the target moisture of the cut stem drying outlet according to the target moisture of the cut stems after the air separation and the change quantity of the cut stem moisture before and after the target air separation.
The method comprises the steps of firstly calculating the moisture variation of the cut stems before and after target air separation corresponding to the environmental humidity according to the environmental humidity of an actual production workshop, then calculating the target moisture h of the cut stem drying outlet according to the moisture variation g of the cut stems before and after the target air separation and the target moisture f of the cut stems after the air separation, and setting the target moisture value of the cut stem drying outlet in the drying process of the cut stems to perform production, so that the finished cut stems are ensured to meet the process standard. Specifically, h ═ f + g.
According to the invention, the prediction relation between the moisture variation of the cut stems before and after the air separation and the workshop humidity is established, the target moisture of the cut stems at the drying outlet is accurately obtained according to the target moisture after the air separation of the cut stems on the basis of the prediction relation, and the target moisture of the cut stem drying outlet is set according to the target moisture in the drying process, so that the moisture content of the finished cut stems obtained by the subsequent process can meet the standard, and the qualified rate of the finished cut stems is improved. Furthermore, in the process of calculating the target moisture after the air separation, the target moisture after the air separation corresponding to the qualified finished cut stems is calculated by utilizing the moisture changes of the qualified cut stems in a plurality of batches before and after the flavoring process and the moisture changes of the qualified cut stems in a plurality of batches before and after the cut stem storage process, so that a more accurate value of the target moisture after the air separation is obtained.
