For grain, which grains are thick and round and plump and uniform can be regarded as good quality food, actually the harvested grains not only contain these high quality grains, but also contain shrinkage, narrow sinews, and deep and uneven sulcus. There are traces of worm-eaten traces. We often call these granules imperfect granules. To accurately judge grain quality, we need to examine imperfect grains, and the most reliable way to quickly identify imperfect grains is to use them. Computer filter for the determination.
The identification of traditional imperfect grains is based on artificial identification. For example, grasping a handful of wheat is spread out on the table. The line of sight is concentrated in an area of ​​10cm2. It is considered to contain 4 grains of imperfect grains, accounting for about 2.50%; Defective pods with 3 or less imperfect grains with wrinkles or deep groins account for worm-eaten, damaged, mildewed, diseased, sprouted, and other edible particles. This method of relying on visual judgment actually has a relatively large error, which often varies from person to person, so it is difficult to accurately determine the true quality of food. Moreover, with the increase of modern grain production, food transactions are also more frequent and accurate test data are needed as a reference. This time, the use of computer filters is more reliable than manual detection.
The computer filter has also become a computer filter, electric filter, etc. This instrument is a professional food testing instrument developed according to the GB5494-85 "National Standard for Inspection of Impurities and Imperfect Grains of Food Oil", and is specially used for the screening of grain and oil. Compared with the manual method, the computer filter has higher efficiency and better accuracy, which is in line with the needs of modern high-frequency food inspection work. Applying it to the field of grain purchase can ensure the fairness and fairness of the acquisition process and meet the interests of all parties. If it is used for agricultural breeding, it can better sort the varieties of food crops and provide more high-quality and high-yield for modern agricultural production. Seed varieties.
