The specific embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Paper is the concept of dry once, and dry refers to removes materials all after moisture as the summation of fat, protein, carbohydrate and mineral salt in tobacco.
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 belted electronic balance and the Moisture Meter 4 with the belt 5 that transmits tobacco, and belted electronic balance comprises speed encoder 2, LOAD CELLS 3 and controller (not shown).Moisture Meter 4 is arranged on belted electronic balance top, detects the moisture of the tobacco 1 transmitting on belt 5.Controller communicates and is connected with speed encoder 2, LOAD CELLS 3 and Moisture Meter 4, obtains actual dry instantaneous delivery and dry matter accumulation flow by calculating.Speed encoder 2 is arranged on a side of belt, is used for detecting the speed of service of belt 5.LOAD CELLS 3 is arranged on belt 5 and bears the below of a side of tobacco 1, is used for detecting the instantaneous loading of the tobacco transmitting on belt 5.
For the accurate actual moisture of determining in tobacco, preferably, with the infrared moisture infrared moisture meter that carries out moisture detection of pop one's head in, the infrared moisture probe of this Moisture Meter points to the tobacco of transmission on belt 5.
The signal that the signal that controller can provide according to the weighing parts on belted electronic balance and Moisture Meter provide calculates, the dry instantaneous delivery of determining actually and dry matter accumulation flow.The programmed algorithm that controller adopts all can adopt existing mode, below the present invention a kind of explanation of control principle of concrete controller example is also provided, 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 units, comprising: belt speed of service acquiring unit 11, the instantaneous loading acquiring unit 12 of material, material moisture acquiring unit 13, dry instantaneous delivery calculate unit 14 and dry matter accumulation flow rate calculation unit 15.The signal of the speed of service V of the belt 5 that wherein, the responsible inbound pacing encoder 2 of belt speed of service acquiring unit 11 transmits.The signal of the instantaneous loading F of the tobacco 1 transmitting on the belt 5 that the responsible reception LOAD CELLS 3 of the instantaneous loading acquiring unit 12 of material transmits.The signal of the moisture measured value M of the tobacco 1 transmitting on the belt 5 that the reception Moisture Meter 4 of being responsible for material moisture acquiring unit 13 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 F*V is the actual instantaneous delivery of tobacco.
Dry matter accumulation flow rate calculation unit 15 can carry out time-based integration to dry instantaneous delivery P, obtains dry matter accumulation flow W, and 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, the present invention also provides the realization flow of several technical process control methods, 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:
The standard moisture of mentioning in above-mentioned steps 102 is to determine according to the process point processing request in operation stage.In tobacco processing, the desired standard moisture of every procedure is different, may be 19%, may be also 29%, may be also other numerical value, and standard moisture is the theoretical water score value of special process point.Standard moisture corresponding to these operations can be repeatedly determining in actual production, and therefore in step 102, definite standard moisture will be according to setting according to process point processing request corresponding to operation stage after weighing in advance.
In step 103, can convert the instantaneous delivery P of tobacco under standard moisture Ms according to dry instantaneous delivery P and standard moisture Ms
ms, computing formula is:
P
Ms=P/(1-Ms)=F*V*(1-M)/(1-Ms)。
And can convert the integrated flux W of tobacco under standard moisture Ms 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 tobacco unification can be converted to instantaneous delivery and the integrated flux of certain operation stage under standard moisture by step 103 and step 104, and the technology controlling and process of utilizing the instantaneous delivery after conversion to carry out with integrated flux can overcome the different problem of hygroscopicity that tobacco causes because of the difference of the aspects such as the place of production, grade, position.
The example in the operation stage after still using feed liquid interpolation operation as weighing herein describes.Be divided into 29 in standard water corresponding to process point of having determined feed liquid interpolation operation, and the actual moisture of this batch of tobacco is 25, actual instantaneous delivery is 2000kg/H, so in the time that tobacco proceeds to feed liquid interpolation operation, need to convert the instantaneous delivery of tobacco under standard moisture, be 2000* (1-25%)/(1-29%)=2112kg/H, and then carry out the fixed than spraying of feed liquid according to this instantaneous delivery 2112kg/H, the impact thereby the fluctuation of minimizing tobacco moisture is large on following process.In other operations, can also use integrated flux, just give an example no longer separately here.
By the aforementioned explanation to tobacco dry meausring apparatus of the present invention and technical process control method, can the operation stage after weighing the moisture fluctuation of tobacco be foreclosed, really realize the certainty ratio technological operation to various tobacco, obtain meticulousr control effect.
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 the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present invention; 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 protection of the present invention.
