Method for controlling automatic liquor blending by virtue of real-time smell detection technology

Abstract

The invention relates to a method for automatically controlling liquor blending by virtue of a real-time smell detection technology. The method includes contents of a real-time detection method of liquor smell, definition of liquor smell characteristics and an automatic liquor blending control algorithm. The basic flow of the method is as follows: establishing a smell characteristic chromatogram for crude liquor and a sample, and carrying out primary blending and smell detection according to the proportion of the sample so as to obtain the smell characteristic chromatogram of the blended liquor; comparing the smell characteristic vector of the blended liquor with the characteristic vector of the liquor sample, beginning the next turn of blending according to a calculation formula when an error is more than a threshold, and repeating the steps of detecting, comparing and correcting blending until the error is less than the threshold, so that blending is completed and a finished product is obtained. The method disclosed by the invention has the advantages of being highly adaptive to different batches of crude liquors having difference, and being used for rapidly blending different types of flavored liquors and age liquors by changing algorithm parameters.

Description

technical field

[0001] The invention relates to a method for automatically controlling liquor blending by using real-time odor detection, which mainly includes a real-time detection method for liquor smell in the liquor blending production process, a definition of liquor odor characteristics and an automatic liquor blending control algorithm. Background technique

[0002] At present, the liquor industry in my country mainly adopts traditional blending methods for liquor blending, and the common ones are in-tank blending method and large-capacity storage tank blending method. Regardless of the blending method, the formula is generally determined according to the sample, and then the amount of various base wines is calculated. In the blending process, either a pail and a pottery altar are used for blending, or a number of altar base wines are combined in proportion and introduced into a large tank for blending. These manual and semi-automatic blending methods are all based on...
