Abstract

A method for detecting milk components comprises a model building step and a milk detecting step. The model building step is used for building and storing a near infrared spectrum classification and correction model and utilizing the ultrasonic self-exciting frequency to classify the near infrared spectrum of different types of milk and build a near infrared spectrum classification and correctionmodel corresponding to the different types of milk; and the milk detecting step obtains the component content of the milk sample corresponding to the near infrared spectrum classification and correction model according to the ultrasonic self-exciting frequency and near infrared spectrum information of the milk sample to be detected. The device and the method use the ultrasonic self-exciting frequency measuring technology to evaluate the background interference of the milk components, automatically perform the classification of the near infrared spectrum model by means of the ultrasonic and near infrared information fusion and realize quick, accurate, automatic and high-efficient detection of the routine components of the milk.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a detection device and method for detecting milk components by using ultrasonic wave and near-infrared spectrum analysis technology. Background technique [0002] The national standard method for testing the internal components of milk is mainly chemical method. Due to the long time and high cost of chemical analysis of milk components, rapid, non-contact and automatic detection methods have been proposed. At present, there are mainly mid-infrared spectroscopy, near-infrared spectroscopy and ultrasonic analysis. Both mid-infrared spectroscopy and ultrasonic analysis have corresponding commercial instruments available, and the chemical method is the national standard method, which is the benchmark as the standard method. [0003] The chemical analysis method, in the national standard, has strict regulations on the indicators and testing of raw milk, pasteurized milk, ...
