For the hierarchical objectives line of the high, medium and low albumen of albumen powder；The control device is according to the testing result control of the hierarchical detection device
Make the automatic classification that the material transmitting device completes the albumen powder.
In-line analyzer I 2 in hierarchical detection device uses near-infrared spectral analysis technology, which is to utilize near-infrared
The effective information that spectrum area includes, carries out qualitative or quantitative analytical technology to substance by computer hardware technique, is current
Quick, the lossless PAT technology of the one kind quickly grow, having a extensive future.
The effect that the reasonability of the classification of albumen powder directly determines the capacity of each albumen tank and finally matches.As directly adopted
It is classified with the fixed upper limit, lower limit and intermediate limit, the effect of classification can lead to some egg due to the unstability of production
The white quick canful of tank, some quick slack tank, unreasonable distribution.It is classified in the present embodiment using dynamic limitation, classification effect
Fruit will not because of protein content in material fluctuation and lead to undesirable effect.
Moving average method (moving average) is also known as the method for moving average.On the basis of simple average method, by suitable
Sequence increases and decreases new and old data calculation moving average by the phase, so as to eliminating accidental fluctuation factor, finds out things development trend, and accordingly
It is predicted.The length of time of the window of sliding is determined according to the amount of storage of tank body.
The stable calculation of albumen powder material goes to calculate and assess using window sliding standard deviation, is exactly product in given time
The value of standard deviation.Standard deviation is also referred to as standard deviation, and standard deviation (Standard Deviation) describes each data and deviates
The average of the distance (deviation from average) of average, it is the root after sum of squares of deviations is average, is indicated with σ.σ is a kind of measurement number
According to the standard for dividing spread of distribution, the degree of arithmetic mean of instantaneous value, that is, material stability are deviateed to measure data value.Mark
Quasi- deviation is smaller, these value deviation averages are fewer, and material stability is better, and vice versa.The size of standard deviation can lead to
Cross the multiplying power relationship of standard deviation and average value to measure, as shown in Fig. 3.
Sample standard deviation
Sample X used by representing1,X2,...,XnMean value.
Albumen powder stock grading upper limit standard adds and subtracts a standard deviation multiplied by a coefficient conduct using sliding average
Upper and lower bound is classified.
Upper limit UL (Upper Line)=Average+a*SD
Lower limit LL (Lower Line)=Average+a*SD
The protein content of normal production of albumen powder complies fully with normal distribution, therefore the coefficient of standard deviation is with regard to direct
Determine the ratio for entering different albumen powder tanks.
In the present embodiment, the inlet amount in order to guarantee three albumen powder tanks is relatively uniform, adds and subtracts 0.5 times using average value
Standard deviation is 19.1%+19.1%=38.2%, the i.e. charging of albumen tank III 8 as grade scale, the ratio of albumen tank III 8
Amount accounts for the 38.2% of total feed, and the inventory of albumen tank II 7 and albumen tank I 6 is (100%-38.2%)/2=30.9%,
As shown in Fig. 5.
Specifically, it is determined that material albumen powder from test point to the first feed opening, the second feed opening and third feed opening when
Between, the time control that automatic plate I 3 and automatic plate II 5 for classification switch, such as by the first feed opening 5 seconds, under second
Material mouth 10 seconds, third feed opening 15 seconds, the sliding average for the albumen powder content that can be detected according to continuous 5 seconds line analysis instrument I 2
For value as albumen powder into the criterion of tank, the standard deviation of 0.5 times of plus-minus is upper and lower grading control line, with above-mentioned control line with
Standard deviation is control benchmark, and in albumen powder classification process, control III 8 sub-material quality accounting of albumen tank is 38.2%, albumen
I 6 sub-material quality accounting of tank is 30.9&, and II 7 sub-material quality accounting of albumen tank is 30.9%, as shown in Fig. 4.Specifically, according to
Line (59%) centered on one hour sliding average data is closed on, the product standard deviation of setting is as standard, egg
The target height that Bai Hanliang is classified online is limited to 60%, and target lower bound is 58%, when the detection of in-line analyzer I 2 in continuous time
When protein content in albumen powder is located in the standard deviation proportional region of the hierarchical objectives line, albumen powder enters the albumen
Tank III 8；When the protein content in the albumen powder that in-line analyzer I 2 detects in continuous time is higher than the upper of the hierarchical objectives line
When deviation, albumen powder enters the albumen tank II 7；When the albumen in the albumen powder that in-line analyzer I 2 detects in continuous time contains
When amount is lower than the lower deviation of the hierarchical objectives line, the albumen powder enters the albumen tank I 6, completes albumen powder hierarchical detection.
In the present embodiment, albumen powder in the albumen tank III 8 not fracture, the material position of albumen powder in the albumen tank III 8
Height and discharging speed are relative constant.Albumen powder in the albumen tank I 6, albumen tank II 7 not fracture, in the mixing of albumen powder
The albumen tank I 6 is controlled in the process, the feeding speed of albumen tank II 7 deploys protein content at any time.The albumen tank I 6, albumen
A certain amount of albumen powder is cached in tank II 7 and albumen tank III 8, the albumen powder of caching is the 1/ of each albumen tank bearing capacity
2-2/3.Albumen powder material position in the albumen tank I 6, albumen tank II 7 and albumen tank III 8 reaches full level alarm, accelerates discharging, institute
State the height of material position and the speed dynamic equilibrium of discharging；Any full level alarm in the albumen tank I 6, II 7 the two of albumen tank, separately
One albumen tank starts simultaneously, guarantees that material position does not transfinite, and protein content is controllable；The albumen tank I 6, II 7 and of albumen tank
Albumen powder material position in albumen tank III 8 reaches low alarm, discharging of slowing down.In protein content control process, in albumen tank III 8
The uninterrupted constant output of albumen powder, at least one operation in the albumen tank I 6, albumen tank II 7, or synchronous operation (egg
Bai Hanliang height neutralizes), with regulatory protein content, guarantee that the protein content in product is stablized.
Specifically, the albumen powder passes through frequency conversion rotary valve I 10, frequency conversion rotary valve II 11, frequency conversion rotary valve III 12 and material mixing
Device completes the mixed at high speed of different stage albumen powder, and will test result by in-line analyzer II 14 and feed back to the control
Device；Target value of the control device according to in-line analyzer II 14 the real-time detection result and product, passes through the change
Frequency rotary valve I 10, frequency conversion rotary valve II 11, frequency conversion rotary valve III 12 control the albumen powder in each albumen tank and mix dress to the material
The discharging speed set, completes the automatic governing of protein content, it can be achieved that the fluctuation of the protein content of product is within 2%, such as attached
Shown in Fig. 4.Wherein in-line analyzer II 14 is identical as in-line analyzer I 2, similarly uses near-infrared spectral analysis technology, into
Row sweeping type real-time detection, control device control hierarchical detection device, proportion detection device and automatic by the way of PID/feedback
Matching device, including proportional component, integral element and differentiation element, the blanking of the PID process control difference albumen tank of preferably PLC
Speed, as shown in Fig. 6, hierarchical detection device, proportion detection device sent real-time detector data to PLC at interval of 10 seconds,
Adjusting optimization is carried out to pid parameter, is rapidly achieved the dynamic equilibrium of discharging protein content.
