Ultrasonic wave milk components analysis instrument

Abstract

The invention discloses an ultrasonic analyzer of the milk components. It includes: AT89C52 singlechip, the interface composed of LCD, press key and RS232, EEPROM location, liquid pump and the detecting system composed of the ultrasonic probe, temperature-control circuit, oscillating circuit, power amplifying circuit and threshold-value detecting circuit. It has advantages of wider temperature range (15-40 deg.C) for testing the sample and the emitting signal with a certain frequency and voltage and a one-off detection and analysis of the fat, protein, density, freezing point and so on in themilk.

Description

technical field [0001] The invention relates to ultrasonic detection technology, and is an ultrasonic milk component analyzer. Background technique [0002] Milk composition analysis is a necessary link in the purchase of raw milk based on quality and price evaluation and product quality monitoring in the production process. Traditional milk composition analysis uses chemical analysis technology, which requires chemical analysis of milk fat, solids, density, and protein content. Among them, the analysis of fat content is based on the difference in density between fat and other components, and is determined after separation by a milk fat separator; the solid content is measured by weighing after drying; the density is measured by a densitometer; the protein is determined by Kjeldahl method Determination. The whole analysis process often takes 1-2 days, which is time-consuming and labor-intensive. At the same time, various chemical analysis instruments ...
