Portable grain quality rapid nondestructive detection and identification device

The invention belongs to the technical field of agricultural product detection, and relates to a portable grain quality rapid nondestructive detection and identification device which comprises a shell, a spectrum acquisition unit, a data transmission and processing unit, a circuit unit and a heat dissipation unit. The spectrum acquisition unit is used for acquiring spectrum information of to-be-detected grains, and the data transmission and processing unit is used for processing, calculating and storing data; and a micro processing system in the data transmission and processing unit is internally provided with different quality prediction models of different types of to-be-detected grains, the micro processing system calculates quality index parameters of an object to be detected according to the corresponding models, the grade of the detected grains is identified according to the detected indexes, and a detection result is displayed on a liquid crystal display screen in real time. According to the invention,
