The concept of weight and its measuring method The bulk density of grain refers to the quality of grains in a certain container. It is a physical quantity closely related to the porosity. The bulk density is inversely proportional to the porosity. In the process of food circulation, it is an important indicator to test the quality and quality of wheat. In China, many of the current quality standards for food, such as wheat, corn, etc., have taken bulk density as the basic indicator of determination. Container weight is a professional instrument for determining the bulk density of grain. In the major wheat producing countries of the world, such as the United States, Canada, Australia, and other countries, the bulk density is also ranked first in the quality standard. The size of the bulk density is grain size, quality, shape, uniformity, depth of abdomen, texture of the endosperm, The comprehensive reflection of traits and characteristics such as powder yield. In general, the grain bulk density of the same variety is related to the maturity, fullness, size and uniformity of the grain, the surface finish and the hardness rate. The grains of the grain are mature, full, neat and tidy, and have high hardness and smooth surface. The weight density is higher; conversely, the bulk density is lower. Relevant studies have shown that the wheat grain weight has a certain relationship with the protein content, sedimentation value and hardness, and there is also a certain proportional relationship between the bulk density and the total starch content. The higher the grain moisture content, the lower the bulk density. The amylose measuring instrument is the key instrument for determining the starch content of wheat. After measuring the starch content, combined with the content of wheat bulk density, we can obtain the relationship between the wheat bulk density and the starch content. How is the weight of wheat measured? The determination of the bulk density of wheat can refer to GB/T 5498-85. The samples were not subjected to the screening of cereals, and the original samples were directly used as the samples for determining the bulk density. In addition, there is a special container-heavy weight container for wheat, which is based on the LS/T3701-1993 "HGT-1000 Grain Cessel Container" standard and standard "reference standard" and GB1353-2009 "maize" in the new national standard. Developed to measure grain bulk density requirements. The container weight is widely used in the measurement of the bulk density of crops such as wheat, rice, sorghum, and corn.
