Description
Technical field
The utility model belongs to black tea manufacture equipment technical field, is specifically related to the discriminating gear of a kind of congou tea fermentation appropriateness.
Background technology
Fermentation is the critical process of congou tea processing, directly determines into the quality and flavor characteristic of sampling tea.The change of a series of sense organ is presented at goods (fermentated leaves), the change as color and luster: dark green-bluish yellow look-yellow-yellowish red color-redness-copper-crineous gradually in whole fermentation of black tea process.In existing domestic and international fermentation of black tea quality appropriateness detection method on, all according to this variation phenomenon, differentiated by the artificial sense of tea making master worker " two hear at a glance ", namely the visual color change of fermentated leaves is first observed, odor characteristics and the strong degree of volatilization is differentiated in sense of smell again, and whether the knowhow of the final people of relying on judges to ferment appropriate.The method is subject to experience and the impact of artificial subjective factor of tea making master worker, and easily cause fermentation of black tea partially light or excessive, cause stability and the poor consistency of product quality, style, quality safety risk factors greatly increase.
Notification number is the new method that the Chinese invention patent of CN101319990B discloses a kind of appropriateness of determining to ferment in congou tea process, the method is: the absorbance (s) detecting the millet paste after the fermentate immersion of different fermentations time, absorbance change includes theaflavin change to cause, when absorbance ascensional range flattens slow (Δ s < 0.005), or when starting to decline, be now the fermentation appropriateness time.But theaflavin is transformed by polyphenols, by the impact of tea tree breed and fermentation condition, the growing amount of theaflavin has a great difference.In addition, the theaflavin generated in course of fermentation is also transforming to multiple approach such as thearubigins, and have impact on the accuracy utilizing theaflavin relative content to judge fermentation of black tea appropriateness further, the method also exists the limitation of application.
Notification number is recognition methods and the device that the Chinese invention patent of CN103134795 discloses a kind of fermentation moderate point of black tea, this invention is the recognition methods of fermentation moderate point of black tea, the reflective middle RGB light of fermentated leaves is respectively RGB, method is the fermentation index F1=R/G of the fermentation appropriateness point first obtaining certain black tea kind, and F2=R/ (R+G+B) parameter value is held time T1, T2; Gather F1, F2 of calculating fermentated leaves again, hold time when platform and reach T1 or T2, namely reach the appropriate point of fermentation.This invention solves the consistance that fermentation appropriateness point identifies in theory, but in fact in fermentation of black tea process, the process of mainly red stain, phase color change is very slow after fermentation, and the sensitivity of color sensor be difficult to accomplish accurately to identify R G B value.
Notification number is the decision method that CN103424520A Chinese invention patent discloses a kind of fermentation of black tea appropriateness, namely when fermentation of black tea process starts 0h, get fermentated leaves sample determination and record EGCG content, the every 0.5h of recycling color difference meter gets the detection that fermentated leaves sample carries out form and aspect Hab value, it is little to there is color difference meter hot spot in the method, sample representation is not accurate enough causes larger Acquisition Error, and EGCG content is slow for detection time simultaneously, is difficult to meet the requirement of online Fast nondestructive evaluation in producing.
Notification number is the method and apparatus that CN103777524 A Chinese invention patent discloses a kind of black tea proper fermentation based on visible spectrum technology and controls.It controls by computing machine the reflectance spectrum that optical fiber meter gathers fermentate visible ray, and the chromatic value and the aim colour angle value that calculate fermentate are shown in aberration; When aberration is less than the threshold value of setting, think that fermentation is appropriate.Because the hot spot of optical fiber only has 3-5mm, strip black tea is kneaded breakage to be affected, even if the color of same tablet tea leaf surface is also uneven, therefore the not high error that certainly will cause of measuring point samples' representativeness is larger, the fermentation being only applicable to external red fannings detects, and is not suitable for the distinctive bar shaped congou tea of China.
