Portable flour multi-quality detector based on near infrared and detection method

Abstract

The invention discloses a portable flour multi-quality detector based on near infrared and a detection method. The detector comprises a case, and a power supply, a light source module, a spectrum acquisition module and a control processing module which are arranged on the case, the light source module comprises a detection accessory, the detection accessory comprises an objective table, a light source seat, a light source cover, a sample reference box, a reflecting cover, an optical fiber collimating mirror, a height adjusting mechanism and a halogen lamp bead; the spectrum acquisition modulecomprises a spectrograph, and the spectrograph is connected with an optical fiber collimating mirror through an optical fiber; the control processing module comprises a circuit board, an embedded computer and a liquid crystal display screen, the embedded computer is connected with the halogen lamp beads through the circuit board, the spectrograph is connected with the embedded computer, and the embedded computer is connected with the liquid crystal display screen. The detector is compact in structure, complete in function, light, handy, portable, high in universality, capable of moving everywhere, simple in detection method, capable of effectively detecting whether the moisture value and the DON value of a sample exceed the standard or not and high in detection precision.

Description

technical field [0001] The invention relates to a near-infrared quality detection technology, in particular to a near-infrared-based portable flour multi-quality detector and a detection method. Background technique [0002] As one of the three major crops in my country, wheat is rich in nutrition. It can not only solve the food and clothing problem of human beings, but also can be used as a feed and industrial raw material. However, wheat is very susceptible to damp and infected with head blight, which will not only destroy the cell structure of wheat, reduce yield, but also cause vomiting, anorexia and carcinogenic vomiting toxin (DON). Generally, heating cannot destroy its structure. Since my country stipulates that the content of DON in wheat flour is <=1mg / kg, it is extremely important to accurately predict the moisture and DON content in wheat for the safety of wheat food. Generally, wheat needs to be milled to make food, so it is particularly important to study t...

Problems solved by technology

But most of them are still in the laboratory research and cannot be used in the actual production environment

Moreover, most of the instruments on the market are used to detect the protein and starch content in flour, which does not reflect the safety of flour.
