Method and device for quickly and nondestructively judging processing precision grade of rice

Abstract

The invention discloses a method and a device for quickly and nondestructively judging the processing precision grade of rice. The method comprises the following steps: collecting rice bran powder samples with different processing precisions; collecting near infrared spectrum data of the bran powder sample; obtaining the organic component content of the bran powder sample; establishing an infraredspectrum correction model according to the near infrared spectrum data and the organic component content; obtaining a relation model between the rice processing precision grade and the organic component content of the bran powder; judging the current processing precision grade of the rice and adjusting the grinding degree of the rice according to the current processing precision grade. The methodhas the advantages that the rice processing precision is regulated and controlled on line, and the limitation in practical application is reduced.

Description

Technical field

[0001] The invention relates to the field of rice processing, and more specifically to a method and device for quickly and non-destructively judging rice processing precision grades. Background technique

[0002] Rice is one of the three major food crops in the world, and about two-thirds of the population in my country rely on rice as the staple food. The output and quality of rice have a major impact on my country's food security and residents' diet. Genetic breeding methods provide technical means to increase rice yield. On the other hand, the rice processing process plays an important role in increasing the yield and quality of rice. Rice is obtained from rice hulling, milling, polishing and other processes. The processing process of rice is mainly to remove the components of the bran layer on the surface of the rice embryo. The bran layer is rich in fat, protein, minerals and vitamins. The improvement of the sensory quality of the rice during the processing...

Embodiment 1

[0042] Such as figure 1 As shown, a method for quickly and non-destructively determining the precision level of rice processing includes:

[0043] Step S1: Collect rice bran powder samples with different processing precisions; in this embodiment, a total of 77 bran powder samples are collected. Among them, 47 samples of bran powder with different grinding degrees were collected in the rice processing line of Shuanghu Grain and Oil Company in Shou County, Anhui Province, which has three rice milling procedures. The remaining 30 bran meal samples came from 30 rice varieties with different genetic backgrounds. These rice varieties are harvested, hulled, and milled in a laboratory using rice polishing machines on Science Island in Hefei, Anhui Province, China. The schematic diagram of rice production and processing and the collection position of rice and bran powder are as follows figure 2 Shown. The rice processing process includes successively connected rice hulling machines, se...
