Abstract
The invention discloses a method for improving stability of outlet moisture of a stem moistening machine in a stub bar stage. The method comprises the following steps: 1) determining a stub bar water addition amount: when production reaches a stable state, measuring loosing and rewetting outlet moisture and calculating an outlet moisture deviation, and after the outlet moisture deviation is less than a set deviation and a set time lastingly, calculating the average a of loosing and rewetting water addition flow within the set time; and 2) segmentally adding water into stub bars. Through training of the stub bar water addition amount, a water addition amount which can be used as a basis is found, and water addition amounts in different stages of the stub bars are determined by a linear approximation method, and thus quantified, so that a basis for reasonably regulating the water addition amounts is provided, and the stability of the outlet moisture in the stub bar stage is improved.
Description
Technical field
The present invention relates to a kind of method for improving terrier machine stub bar stage moisture content of outlet stability.
Background technology
Terrier operation uses scraper type offal moisture regaining machine, for obstructing cabo pretreatment section in line, it is therefore an objective to increase cigarette
Stalk temperature, makes cabo further heat moisture regain, steams cabo saturating, improves the overall flexibility of cabo, is further adding for cabo
Work provides condition.Moisture content of outlet is the key index of terrier operation.
Moisture content of outlet uses feedback control, i.e., remove real-time adjustment amount of water according to the detected value of Moisture Meter.In production
Initial period, Jing after loosening and gaining moisture processing, moisture content need to could be controlled in the range of standard is required smoked sheet through a period of time,
This process is referred to as stub bar.The stub bar stage is the difficult point of control, because detecting the moisture value of outlet material in this class, is made
The foundation of amount of water must be not adjusted, relatively large deviation often occurs in stub bar stage moisture value, when Moisture Meter can be detected
Then occurs larger vibration when be adjusted after its moisture content of outlet again.And there is presently no effective method and can solve this and ask
Topic.
The content of the invention
It is larger in order to solve stub bar stage moisture value deviation present in prior art, it is difficult to which that accurately the technology of control is asked
Topic, the present invention provide a kind of method for improving terrier machine stub bar stage moisture content of outlet stability.
In order to solve above technical problem, technical scheme is as follows：
A kind of method for improving terrier machine stub bar stage moisture content of outlet stability, comprises the steps：
1) determination of stub bar amount of water：When production is into steady statue, loosening and gaining moisture moisture content of outlet is measured, and is calculated
The deviation of saliva point, after moisture content of outlet deviation is continuously less than the setting deviation setting time, calculates and loosely returns in the setting time
Meansigma methodss a of the flow that adds water of tide；
2) carry out segmentation to stub bar to add water, when Nicotiana tabacum L. cumulative amount be A when, loosening and gaining moisture amount of water be b*a, when A less than etc.
When setting value c, the setting value is the accumulative inventory when exit has material to transport out, b be less than or equal to 1 and more than etc.
Less in 0, A, b is less, and b is the coefficient that adds water.
Preferably, when A is more than setting value c, the flow that adds water adopts feedback control.When A is more than c, exit has had
Material is transported out, and at this time can be controlled the feeding quantity of loosening and gaining moisture, make regulation cleverer by detecting material moisture
It is living.
Preferably, step 1) in, produce into the stabilization sub stage be with the Nicotiana tabacum L. cumulative amount of loosening and gaining moisture be more than 1000kg when
It is defined.
From knowhow, when the cumulative amount of Nicotiana tabacum L. reaches 1000kg, production come into the stabilization sub stage, only when
When production is into the stabilization sub stage, the amount of water of loosening and gaining moisture is just in steady statue, if the deviation of the moisture of outlet material is steady
It is scheduled in a low scope, represents that material moisture tends towards stability, loosening and gaining moisture addition now can be as standard, as follow-up
The reference of production.
Preferably, step 1) in, the setting value of moisture content of outlet deviation is 0.8-1.3%, and it is 10- to continue setting time
20min。
It is further preferred that step 1) in, the setting value of moisture content of outlet deviation is 1%, and it is 10min to continue setting time.
Preferably, after the cumulative amount of Nicotiana tabacum L. is more than 350kg, exit begins with material and transports out.
It is further preferred that step 2) in, when Nicotiana tabacum L. cumulative amount is 0≤A≤100kg, b is 0, by damping machine
Steam carries out loosening and gaining moisture；
When Nicotiana tabacum L. cumulative amount is 100 ＜ A≤150kg, b is 0.2；
When Nicotiana tabacum L. cumulative amount is 150 ＜ A≤200kg, b is 0.5；
When Nicotiana tabacum L. cumulative amount is 200 ＜ A≤250kg, b is 0.8；
When Nicotiana tabacum L. cumulative amount is 250 ＜ A≤350kg, b is 1.
Application of the method for improving terrier machine stub bar stage moisture content of outlet stability in loosening and gaining moisture of tobacco.
The present invention Advantageous Effects be：
The present invention by being trained to stub bar amount of water after, find one can as the addition of foundation, and to material
The addition of the water of the different phase of head is determined using linear approximation method so that the amount of water of stub bar different phase is carried out
Quantify, so foundation is provided for Reasonable adjustment amount of water, improve the stability of stub bar stage moisture content of outlet.
