Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
First introduce the concept of dry, the material all after referring in tobacco and removing moisture of dry is as the summation of fat, protein, carbohydrate and mineral salt.
As shown in Figure 1, be the structural representation of an embodiment of tobacco dry meausring apparatus of the present invention.In the present embodiment, tobacco dry meausring apparatus comprises the belted electronic balance and Moisture Meter 4 with the belt 5 transmitting tobacco, and belted electronic balance comprises speed encoder 2, LOAD CELLS 3 and controller (not shown).Moisture Meter 4 is arranged on above belted electronic balance, detects the moisture of the tobacco 1 that belt 5 transmits.Controller and speed encoder 2, LOAD CELLS 3 and Moisture Meter 4 communicate to connect, and obtain actual dry instantaneous delivery and dry matter accumulation flow by calculating.Speed encoder 2 is arranged on the side of belt, is used for detecting the speed of service of belt 5.LOAD CELLS 3 is arranged on the below that belt 5 bears the side of tobacco 1, is used for detecting the instantaneous loading of the tobacco that belt 5 transmits.
In order to determine the actual moisture in tobacco accurately, preferably carry out the infrared moisture meter of moisture detection with infrared moisture probe, the infrared moisture probe of this Moisture Meter points to the tobacco that belt 5 transmits.
The signal that controller can provide according to the weighing parts on belted electronic balance and the signal that Moisture Meter provides calculate, the dry instantaneous delivery determining actual and dry matter accumulation flow.The programmed algorithm that controller adopts all can adopt existing mode, and below present invention also offers a kind of explanation of control principle of concrete controller example, controller can adopt Programmable Logic Controller, single-chip microcomputer, single board computer etc. to realize.
As shown in Figure 2, be the control principle schematic diagram of tobacco dry meausring apparatus embodiment middle controller of the present invention.In this controller example, inside can be divided into multiple functional unit, comprising: the instantaneous loading acquiring unit 12 of belt speed of service acquiring unit 11, material, material moisture acquiring unit 13, dry instantaneous delivery calculate unit 14 and dry matter accumulation flow rate calculation unit 15.Wherein, belt speed of service acquiring unit 11 is responsible for the signal of the speed of service V of the belt 5 that inbound pacing encoder 2 transmits.Material instantaneous loading acquiring unit 12 is responsible for the signal of the instantaneous loading F receiving the tobacco 1 that the belt 5 of LOAD CELLS 3 transmission transmits.Material moisture acquiring unit 13 is responsible for the signal of the moisture measured value M receiving the tobacco 1 that the belt 5 of Moisture Meter 4 transmission transmits.
Dry instantaneous delivery calculates unit 14 can calculate dry instantaneous delivery P according to the speed of service V, the instantaneous loading F that obtain and moisture measured value M, and computing formula is:
P=F*V*(1-M)。And the actual instantaneous delivery of F*V and tobacco.
Dry matter accumulation flow rate calculation unit 15 can carry out time-based integration to dry instantaneous delivery P, and obtain dry matter accumulation flow W, computing formula is:
W=∫Pdt=∫F*V*(1-M)dt=ΣF*V*(1-M)*T。Wherein, T is computing cycle.
Based on above-mentioned tobacco dry meausring apparatus embodiment, present invention also offers the realization flow of several technical process control method, as shown in Figure 3, for the schematic flow sheet of the technical process control method based on tobacco dry meausring apparatus embodiment of the present invention, this technical process control method comprises the following steps:
Step 101, determine dry instantaneous delivery and the dry matter accumulation flow of the reality of the tobacco by belted electronic balance according to described tobacco dry meausring apparatus;
Step 102, determine corresponding standard moisture according to the process stages of described tobacco after weighing;
Step 103, convert the instantaneous delivery of described tobacco under standard moisture according to described dry instantaneous delivery and described standard moisture;
Step 104, convert the integrated flux of described tobacco under standard moisture according to described dry matter accumulation flow and described standard moisture;
Step 105, carry out technical process control according to the instantaneous delivery of described tobacco under standard moisture after conversion and the process stages of integrated flux after described weighing.
The standard moisture mentioned in above-mentioned steps 102 determines according to the process point processing request of process stages.In tobacco processing, the standard moisture required by every procedure is different, may be 19%, also may be 29%, also may be other numerical value, and standard moisture is the theoretical water score value of special process point.Standard moisture corresponding to these operations can be determined in repeatedly actual production, and the standard moisture therefore determined in a step 102 will set according to process point processing request corresponding according to the process stages after weighing in advance.
The instantaneous delivery P of tobacco under standard moisture Ms can be converted according to dry instantaneous delivery P and standard moisture Ms in step 103
ms, computing formula is:
P
Ms=P/(1-Ms)=F*V*(1-M)/(1-Ms)。
And the integrated flux W of tobacco under standard moisture Ms can be converted according to dry matter accumulation flow W and standard moisture Ms in step 104
ms, computing formula is:
W
Ms=∫P/(1-Ms)dt=∫F*V*(1-M)/(1-Ms)dt。
Just the instantaneous delivery of certain process stages under standard moisture and integrated flux can be converted to by unified for tobacco by step 103 and step 104, and the problem that utilize the instantaneous delivery after conversion and the technology controlling and process that integrated flux carries out to overcome hygroscopicity that tobacco causes because of the difference of the aspects such as the place of production, grade, position is different.
Still be described using feed liquid interpolation operation as the example of the process stages after weighing herein.The standard water corresponding in the process point determining feed liquid interpolation operation is divided into 29, and the actual moisture of this batch of tobacco is 25, actual instantaneous delivery is 2000kg/H, so when tobacco proceeds to feed liquid interpolation operation, then need the instantaneous delivery of conversion tobacco under standard moisture, i.e. 2000* (1-25%)/(1-29%)=2112kg/H, and then according to this instantaneous delivery 2112kg/H carry out feed liquid fixed than spraying, thus reduce the fluctuation of tobacco moisture large and impact on following process.Can also integrated flux be used in other operations, just schematically illustrate no longer separately here.
By the aforementioned explanation to tobacco dry meausring apparatus of the present invention and technical process control method, the fluctuation of the moisture of tobacco can be foreclosed process stages after weighing, real realization, to the certainty ratio technological operation of various different tobacco, obtains meticulousr control effects.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
