Wheat has grades. The higher the grade, the better the quality and the higher the price. The grade of wheat is determined by comprehensively measuring the bulk density, imperfect grain, standard impurities and color of wheat. A comprehensive knowledge of wheat bulk density.
Wheat bulk density refers to the mass of wheat kernels per unit volume expressed in grams per liter (g/L). The bulk density is an important indicator of the fullness of wheat. The well-managed wheat has sufficient grain filling in the late stage, and the bulk density of the grain is high. On the contrary, the wheat with premature aging caused by diseases and insect pests, drought, dry hot wind, etc., is insufficiently filled and the bulk density is low.
Because the specific gravity of endosperm is larger than that of cortex, wheat has high bulk density, more endosperm content, less cortex and higher flour extraction rate. Therefore, bulk density is the main indicator for measuring wheat quality, and it is China and most countries. The main basis for wheat grading is considered to be an important indicator of wheat quality. Therefore, it plays an important role in the process of wheat acquisition, transportation and processing, and has a major economic impact.
According to the grade standard requirements, all kinds of wheat are divided into five grades according to the bulk density, and wheat below the fifth grade is the outer wheat. Among them, level 1 ≥ 790; level 2 ≥ 770; level 3 ≥ 750; level 4 ≥ 730; level 5 ≥ 710, unit is gram / liter (g / L).
At present, in the process of wheat acquisition, transportation, processing, etc., the determination of bulk density is a basic measurement project, and in order to accurately and quickly obtain wheat bulk weight results, the industry generally uses a professional bulk density measuring instrument - wheat bulk weight to carry out Analytical analysis. The instrument is simple and efficient, and the measurement results are accurate and reliable, so it has been widely used in the industry.
