Description
Technical field
The invention belongs to tobacco processing throwing field, and in particular to it is a kind of improve stem flavoring control accuracy method and
Device belongs to the method and apparatus that Flavouring Precision controls in stem manufacturing procedure in tobacco industry throwing process.
Background technology
Traditional perfuming method is in Primary Processing：Stem Perfuming machine be according to producing different kind and trade mark cigarette,
Flavoring ratio is preset according to corresponding cigarette process standard, by acquiring stem actual flow in real time during production control
Signal, calculates the flavoring amount of actual needs, while obtaining the working frequency of Perfuming machine motors of metering pumps frequency converter, real-time tracking
Stem actual flow carries out flavoring.The quality of Flavouring Precision largely depends on the stability of electronic scale constant flow system,
That is the stability and uniformity of mass flow.
Tobacco flavoring mode：When tobacco is transported in flavoring machine cylinder, roller is driven by transmission device to be rotated.By
In the elicitation effect of shovelling plate in the axially inclined and roller of roller so that tobacco can loosely, equably discharge from trend
The flowing of mouth direction.When tobacco is run in roller and when from feed inlet 1.5m or so, pump motor, which starts, starts to work, will be pre-
First prepared spice liquid is continuously sent in the nozzle of equipment feed end.While pump motor starts, compressed air hose
The solenoid valve of road opens simultaneously, and when spice liquid passes through nozzle, compressed air is mixed with, and spice liquid is made to be ejected in mist
It goes, trickles down on tobacco, complete flavoring processing.The flow of pump and the jeting area of nozzle, can adjust in a certain range
It is whole, to meet the requirement of technique.
Traditional dehydration is dried in stem perfuming process, since the moisture of cut stem and flow that enter cut-tobacco drier can not possibly reach
Utopian steady state value, they all in technique allowable range there are certain deviation, while chopping, drying process quality and
Stem storing mode and time are also influenced on drying silk effect and Flavouring Precision.And cause flavoring process inlet mass flow wave
, there is the following in the main reason for dynamic：1, it is the fluctuation of preceding process drying process entrance mass flow；2, due to chopping, baking silk
The fluctuation of the stem amount separated through wind subset wind after silk is dried in the influence of the factors such as quality；3, the rationally distributed property of apparatus and process.
In the actual production process, the fluctuation of stem amount is divided due to the fluctuation of drying process entrance mass flow and by wind
Property, so as to cause the fluctuation of flavoring process inlet material, the cymomotive force (CMF) of this supplied materials flow must influence the matter of perfuming process link
Amount and precision.Original way is to be set in advance to electronic scale flow before stem flavoring, is to dry stem inlet flow rate before stalk
Benchmark, setting range of flow exist:Between 1700kg/h~2600kg/h, electronic scale is artificially then observed by site operation personnel
Blanking measurement pipe height material position situation, notice Central Control Room operator carry out plus-minus flow correction, correct adjustable range and exist：150kg/
Between h~300kg/h.This control method is that have the actuator of operating experience conscientiously to observe by scene, and need timely
It controls operative employee in notice to carry out adjusting plus-minus flow correction value in time, control method is more artificial, extensive, the real-time of control
Difference, tracking effect are undesirable, and Flavouring Precision is difficult to meet manufacturing technique requirent, and, labor more demanding to the attainment of operating personnel
Fatigue resistance is big, easily causes quality accident.
