Abstract
The invention discloses a method for accurately controlling moisture in tobacco processing. Two moisture meters are respectively arranged at links needing to control moisture on a cigarette tobacco shred making line or a threshing and redrying line, the former moisture meter is arranged behind a tobacco shred baking machine or a tobacco roasting machine, the latter moisture meter is arranged behind a cooling machine or a packaging machine, and detection results of the two moisture meters are input into an electrical control system; the moisture value detected by the latter moisture meter provides a correction value for the former moisture meter in real time, and the former moisture meter controls the cut tobacco dryer or the baking machine to operate according to the correction result. The invention can obviously improve the stability and the accuracy of the water control of the related equipment, overcomes the contradiction that the feedback speed and the detection data distortion degree can not be considered in the water detection in the prior art, can obviously improve the water control capability of the equipment and reduce the fluctuation of the water content.
Description
Technical field
The invention belongs to cigarette throwing technical field, be specifically related to a kind of method of on cigarette throwing line or Threshing Re-dry Product Line, accurately controlling moisture.
Background technology
At present, online Moisture Meter each link of being widely used in production of cigarettes is carried out moisture Control.But because in the beating and double roasting of production of cigarettes, throwing process; The material moisture of dry, moisture regain, link such as reinforced is in the continuous variation; Cause detection moisture information feedback to relatively lag behind easily, testing result is not accurate enough, thereby has influence on equipment moisture Control stability and accuracy.To the solution of above problem, more correlative study has been arranged, but thinking all is through under the single Moisture Meter state, to control software and peripheral Study on Conditions and improvement, all exist certain not enough.Several kinds of moisture Control technology using at present and control corresponding effects and limitation be as follows:
Pattern 1: quick feedback mode control (Red River factory throwing line adopts), existing problems are that the moisture central value often departs from (the moisture Control pattern is seen Fig. 1, and the moisture Control effect is seen Fig. 2).
Pattern 2: accurate feedback mode control (the old throwing line of elder brother's cigarette adopts), existing problems are FEEDBACK CONTROL velocity lag (the moisture Control pattern are seen Fig. 3, and the moisture Control effect is seen Fig. 4).
Mode 3: quick feedback+artificial Correction and Control pattern (the dry employing pattern of redrying), the artificial intervention revised when deviation was big, still often revised (the moisture Control pattern is seen Fig. 5, and the moisture Control effect is seen Fig. 6) not prompt enough.
Summary of the invention
The objective of the invention is to the deficiency to prior art, the accurately method of control moisture that grows tobacco in the processing is provided,, accelerate feedback information speed, improve equipment moisture Control accuracy and stability to improve the water content detection accuracy.
The object of the invention is achieved through following technical scheme.
The one accurately method of control moisture that grows tobacco in the processing; It is characterized in that: the link of needs control moisture on cigarette throwing line or Threshing Re-dry Product Line; Two Moisture Meter are set respectively; Last Moisture Meter is arranged at after cut-tobacco drier or the roasting machine, and back one Moisture Meter is arranged at after cooler or the baling press, and two Moisture Meter testing results are all imported electric control system; One Moisture Meter detected moisture value in back is that previous Moisture Meter provides correction value in real time, is moved according to correction result control cut-tobacco drier or roasting machine by last Moisture Meter, thereby realizes accurate control appliance moisture content of outlet.
Above-mentioned control method; Cigarette industry can be used in and the link of moisture need be controlled; The leaf silk, stem drying, loosening and gaining moisture, the leaves moisting that comprise the throwing line are reinforced, and the blade baking of Threshing Re-dry Product Line, offal baking, leaves moisting moisture regain etc. need the accurately link of control moisture.
Compared with prior art, the present invention has following advantage:
1, can obviously improve the stability and the accuracy of relevant device moisture Control.
2, can solve in dry (redrying line) link of present tobacco shreds drying (throwing line) or blade, water content detection can not be taken into account feedback speed and the contradiction that detects the data distortion degree.
3, solve blade baking in the redrying line, links such as throwing line middle period (stalk) silk drying are the problem of moisture Control difficulty for a long time, can obviously improve the moisture Control ability of equipment, reduces the moisture content fluctuation.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain, but they are not the restriction to technical scheme of the present invention.
Embodiment 1
The present invention accurately controls the application example of the method for moisture in throwing line leaf silk, the dry link of stem.As shown in Figure 8, at tobacco-dryer exit first Moisture Meter is set, the cooler outlet is provided with second Moisture Meter.Because the cooler outlet detects the moisture value accuracy good; The moisture value input control computer that is detected; Carry out PID calculating with the moisture value of cooling back standard-required, calculate correction value, this correction value forms baking silk moisture content of outlet standard value; The baking silk moisture content of outlet value that detects with first Moisture Meter compares, and based on comparative result cut-tobacco drier is carried out PID and calculates and control.Operational effect is analyzed like Fig. 9.
Border operational effect factually; After using two moisture inter-linked controlling methods at Honghe Cigarette Factory's throwing line; Leaf silk cooling back moisture value standard deviation descends from original 0.17% and reaches 0.10%, and finished cut tobacco moisture value standard deviation drops to 0.10% from original 0.16%.
Embodiment 2
The present invention accurately controls the application example of the method for moisture in Threshing Re-dry Product Line blade redrying link.Shown in figure 10, in the roasting machine outlet of blade first Moisture Meter is set, the baling press outlet is provided with second Moisture Meter.Because the baling press outlet detects the moisture value accuracy good; The moisture value input control computer that is detected; Carry out PID calculating with the moisture value of packing back standard-required, calculate correction value, this correction value forms roasting machine moisture content of outlet standard value; The roasting machine moisture content of outlet value that detects with first Moisture Meter compares, and according to comparative result roasting machine machine is carried out PID and calculates and control.Operational effect is analyzed like Figure 11.
Border operational effect factually, after using two moisture inter-linked controlling methods in Honghe Cigarette Factory's Threshing Re-dry Product Line, finished product tobacco bale moisture value standard deviation descends from original 0.26% and reaches 0.16%.
