Study Of The Rapid Multi-channel Milk Protein Detector

Protein, as a major component of milk, whose quality direct affect the health of human body. And the protein content is an important criterion of milk. For the aim of accurate detection of protein in milk, In this paper we conduct the research and experiment to a multi-channel milk protein detector, and the main work is down as follows;The overall design scheme is put forward based on technical index which included the selection of operational principle,the whole machine frame and the design of sample rotary table of the detector; according to the design, hardware part was designed which included the selection of the stepper motor, optical sensor, microcontroller, screen and printer etc., the design of the constructional mechanical structure of the detector, optical detection system, control circuit etc. A display program of the upper and lower monitor was wrote in advance to display the result of protein concentration in milk,a verification test was conducted on the detector to validate the feasibility of the prototype. And achieved the goal of successful and rapid detection.According to the research requirement,a multi-channel milk protein detector was developed,which have positive effect on improving the accuracy and rapidity of the detector in detection of protein content in milk.
