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 that improves terrier machine stub bar stage moisture content of outlet stability.
Background technology
What terrier operation adopted is scraper type offal moisture regaining machine, and for obstructing line offal pretreatment section, object is to increase offal temperatureDegree, makes the offal moisture regain of further heating, and offal is steamed thoroughly, and the overall flexibility of raising offal, is the further processing of offalCondition is provided. Moisture content of outlet is the key index of terrier operation.
What moisture content of outlet adopted is FEEDBACK CONTROL, removes to adjust in real time amount of water according to the detected value of Moisture Meter. Initial in productionIn the stage, smoked sheet is after loosening and gaining moisture processing, and moisture content need be through being just controlled in the scope of standard-required after a while, thisIndividual process is called stub bar. The stub bar stage is the difficult point of controlling, and because of the moisture value that outlet material cannot be detected in this class, makesMust not adjust the foundation of amount of water, tend to occur relatively large deviation at stub bar stage moisture value, when Moisture Meter can detectWhile adjustment again after its moisture content of outlet, there is larger vibration. And also do not have at present effective method to address this problem.
Summary of the invention
Larger in order to solve the stub bar stage moisture value deviation existing in prior art, be difficult to the accurately technical problem of control, thisInvention provides a kind of method that improves terrier machine stub bar stage moisture content of outlet stability.
In order to solve above technical problem, technical scheme of the present invention is as follows:
A method that improves terrier machine stub bar stage moisture content of outlet stability, comprises the steps:
1) determining of stub bar amount of water: in the time that production enters stable state, measure loosening and gaining moisture moisture content of outlet, and calculate outletThe deviation of moisture, sets after the deviation setting time when moisture content of outlet deviation continues to be less than, and calculates loosening and gaining moisture in this setting-up timeThe mean value a that adds discharge;
2) stub bar is carried out to segmentation and add water, in the time that tobacco leaf cumulative amount is A, loosening and gaining moisture amount of water is b*a, when A is less than etc.In setting value, when c, this setting value is the accumulative total inventory in the time that exit has mass transport out, and b is less than or equal to 1 and be greater thanEqual 0, A less, b is less, and b is for adding water coefficient.
Preferably, in the time that A is greater than setting value c, adds discharge and adopt FEEDBACK CONTROL. In the time that A is greater than c, exitThere is mass transport out, at this time can, by detecting material moisture, control the feeding quantity of loosening and gaining moisture, made to regulate moreAdd flexibly.
Preferably, step 1) in, produce enter the stabilization sub stage be while being greater than 1000kg taking the tobacco leaf cumulative amount of loosening and gaining moisture asAccurate.
From knowhow, in the time that the cumulative amount of tobacco leaf reaches 1000kg, produce and entered the stabilization sub stage, only have when rawWhen product enters the stabilization sub stage, the amount of water of loosening and gaining moisture is just in stable state, if the deviation of the moisture of outlet material is stableIn a low scope, represent that material moisture tends towards stability, loosening and gaining moisture addition now can be used as standard, as follow-upThe reference of producing.
Preferably, step 1) in, the setting value of moisture content of outlet deviation is 0.8-1.3%, lasting setting-up time is 10-20min.
Further preferred, step 1) in, the setting value of moisture content of outlet deviation is 1%, lasting setting-up time is 10min.
Preferably, when the cumulative amount of tobacco leaf is greater than after 350kg, exit starts to have mass transport out.
Further preferred, step 2) in, in the time that tobacco leaf cumulative amount is 0≤A≤100kg, b is 0, relies in damping machineSteam carry out loosening and gaining moisture;
In the time that tobacco leaf cumulative amount is 100 < A≤150kg, b is 0.2;
In the time that tobacco leaf cumulative amount is 150 < A≤200kg, b is 0.5;
In the time that tobacco leaf cumulative amount is 200 < A≤250kg, b is 0.8;
In the time that tobacco leaf cumulative amount is 250 < A≤350kg, b is 1.
The application of the method for described raising terrier machine stub bar stage moisture content of outlet stability in loosening and gaining moisture of tobacco.
Useful technique effect of the present invention is:
The present invention, by after stub bar amount of water is trained, finds an addition that can be used as foundation, and to stub barThe addition of the water of different phase utilizes linear approximation method to determine, the amount of water of stub bar different phase is measuredChange, institute thinks that reasonable adjustment amount of water provides foundation, has improved the stability of stub bar stage moisture content of outlet.
