Description
Technical field
The present invention relates to a kind of white wine and automatically blend equipment, particularly relate to and a kind ofly automatically can blend system according to the white wine of electronic tongue on-line checkingi.
Background technology
White wine is formed primarily of minor compounds such as water, ethanol, other alcohols, acid, ester, aldehyde.Wherein, the massfraction of second alcohol and water reaches 98 ~ 99%.Other miscellaneous trace ingredients presses different ratios composition of relations, forms different odor types and style.The wine of equal in quality grade in unified liquor-making enterprises, local flavor is also different, and some aftertaste are shorter, the slightly assorted taste that has, the sweet taste that has are not enough.Therefore, by various blending process, differently flavoured wine mixed in specific proportions, can supply a gap, learn from other's strong points to offset one's weaknesses, make vinosity more perfect.If ratio is proper, the comparatively extreme low-grade base wine of multiple local flavor supplements mutually, can obtain the good white wine of vinosity; Otherwise multiple high-quality wine is improper because of ratio, so that fragrance is not outstanding or occur assorted taste, reduces class.White wine blend in process, first differently flavoured more than 3 years ageing wine is divided into a few class base liquor (being called for short base wine), carry out small-sized blending (being commonly called as shallow bid to hook) with less amount again, optimize the local flavor of white wine finally by seasoning and seasoning further.Using the small-sized ratio determined of blending as formula, amplify the amount of each base wine, large-scale blending can be carried out and go into operation.
The most direct, the effective foundation of formula is determined in sensory evaluation.At present, in liquor-making enterprises, constantly revise small-sized each base wine ratio of blending in process with Chang Youyi or a few teacher of sampling wine by the sense of smell of human body, the sense of taste.But blending in production process large-scale, also there is quality discrepancy because of batch difference in same base wine.Because base wine during the fermentation, except raw material, many uncontrollable factors such as weather, environment, human users all can affect its local flavor; On the other hand, the storage time of base wine and the difference in place also can produce certain impact to local flavor.Because the large-scale base wine consumption blending process is larger, consuming time longer, therefore require to carry out continuous fine-tuning recipes according to the sensory evaluation of blending intermediates during the course, thus eliminate the reduction of the product quality that base wine difference is brought.But the impact being vulnerable to environment and subjective factor of manually sampling wine causes, except this conclusion of base wine ratio adjustment amount, the personnel of sampling wine cannot provide other quantitative intermediary outcomes.According to the qualitative vocabulary such as " slightly pained ", " entrance is poor ", be difficult to ensure all proposes to meet the suggestion of uniform formula adjustment blending for a long time in process at every turn.
To sum up, blend in process and adjust each base wine ratio by the sensory evaluation of teacher of the sampling wine, meeting at substantial manpower and time, prolongation are blent the cycle, are subject to the impact of teacher of the sampling wine's subjective factor, are very uneconomical, the efficient ways of one.For this phenomenon, need in the system of blending, introduce a kind of quantitative, online white wine quality measurement method, replace traditional artificial sense evaluation.The basic taste sensation such as sweet in white wine, bitter, puckery, peppery all can obtain respective response on the sensor array of α-Astree electronic tongue, and then can be represented quantitatively.Choose a large amount of different year, grade, price wine sample, record respective electronic tongue response message respectively, then by the mathematical tool such as principle component analysis, partial least squares regression Modling model, thus provide Q factor quantitatively according to white wine sense of taste information.
The present invention introduces electronic tongue measuring technology, and suitably improves hardware and algorithm according to the feature of the system of blending, and proposes a kind of white wine based on electronic tongue on-line checkingi on this basis and automatically blends system.First computer controls the data that multi-channel data acquisition board gathers pressure liquid level sensor, temperature sensor, turbo flow meter, electronic tongue, then after algorithm calculates by controlling the working order of each magnetic valve and pump to control wholely to blend process.

Embodiment
Illustrate further below in conjunction with accompanying drawing and specific examples:
Before blending, first to choose base wine sample representative in a large number, measure their electronic tongue response message, obtain electronic tongue response signal as shown in Figure 3.And the quantitative relationship of electronic tongue response and Q factor is set up by the mathematical tool such as principle component analysis, partial least squares regression.According to blending schema 2, at the beginning of blending beginning, blending with small-sized the initial proportion that formula that (shallow bid hook) determine arranges each base wine, and recording small-sized electronic tongue response message of blending product.Large-scale blend beginning after, first provide ratio to blend in advance according to sample, ratio of blending is controlled by the flow sensor 7 in Fig. 1 and liquid magnetic valve 6.For a certain base wine, before reaching ratio, multi-channel data acquisition board 13 makes its respective channel be held open by the rly. controlling in-line pump 5 and liquid magnetic valve 6, period measures flow by turbo flow meter 7, and utilize the data streams amount of temperature sensor 2 to revise, by the data of level pressure sensor 3 in conjunction with the white wine surplus in each tank of monitoring temperature.After ratio arrives, the magnetic valve of all pipelines is in closing condition, and pressurized air is entered by pipeline after filtration to be blent bottom tank 8, stirs the white wine blent in tank 8.
After the above-mentioned process of blending completes, measure the electronic tongue response of blended liquor and Ge Ji wine respectively.First by the white wine Q factor that the sense of taste information acquisition of blended liquor is quantitative, algorithm is according to this parameter and small-sized difference of blending product, and a certain base wine ratio of appropriate adjustment, measures the electronic tongue response of blended liquor afterwards.Respond by electronic tongue the Q factor characterized according to this twice to contrast, by the variation tendency of quality, judge that whether this base wine is useful to the process of blending, and then calculated each base wine ratio needing when next one is blent to supplement by regression algorithm.Circulation like this, until error is less than setting threshold value, finally makes that large-scale to blend product consistent as much as possible with the small-sized local flavor blending product, eliminates the impacts on quality product such as raw material, technique, subjective factor.
