Check method of rice processing precision

Abstract

The invention relates to a check method of rice processing precision, which is mainly used for checking the processing precision of rice. The steps of the check method of rice processing precision areas follows: a sample to be checked is heated, the heating temperature is from 150 DEG C to 250 DEG C, and the heating time is from 1 minutes to 25 minutes to change the color of the left peel of thesample, the left peel degree of the sample is checked by people or instruments, and then the sample is compared with the standard sample to judge the processing precision of the sample. The check method of rice processing precision can eliminate the influence imposed on the check of rice processing precision by chalky rice, realizes the accurate measurement of the rice processing precision, can replace the original dyeing method, does not use chemical agents and has safety and environmental protection.

Description

Technical field [0001] The invention relates to a new method for processing precision of rice, which is mainly used for testing the processing precision of rice, and can also be used for testing the processing precision of sorghum rice, millet, millet and millet. Background technique [0002] The existing rice processing accuracy inspection methods are commonly used in three ways: direct comparison method, dyeing method, and whiteness meter measurement method. The relevant national standards include GB / T5502-85 "Inspection of Grain, Oil Seeds, and Rice Processing". The direct method is to judge the degree of skin retention of rice grains by directly observing the processed samples with the naked eye. Because the color of the cortex of the sample is very similar to the color of the rest, it is difficult to accurately judge the degree of skin retention of rice grains with the naked eye, and the degree of distortion of the test results larger. The second dyeing method is to s...

Problems solved by technology

Although it is much easier and more relaxing to use this method than the direct method to observe, but the staining method must prepare chemical staining agents in advance, the operation is more troublesome, and the cortex of the sample may fall off when soaking, and the chemical staining agent Easy to pollute the environment after use

In addition, the dyeing method cannot eliminate the influence of chalky grains in the sample on the detection of rice processing accuracy.

The third is to use a whiteness meter to measure the processing accuracy of rice. Due to different rice varieties, the whiteness of rice grains has a large difference, which is prone to measurement errors.

It cannot be widely used in practice
