Maize is one of China's three major grain varieties. Grain production accounts for about one-fourth of China's total grain output, and exports are large. At present, the bulk density of corn in China is the only definite index, and there are many factors affecting the result of corn bulk density. Corn bulk density refers to the mass of corn kernels in unit volume, expressed in grams/liter (g/L). As an important indicator of the quality of corn products, bulk density can truly reflect the maturity, completeness, evenness, and use value of corn. The higher the bulk density value of corn of the same variety, the more nutrients contained in the corn grain, and it has become An important indicator of quality in international trade.
The current national standard for corn bulk density is divided into five grades, which can take into account the quality of corn in the northeastern and northern parts of China, and in the main producing areas in their harvest years, average years and apologies. At the same time, all grades can be consistent with the requirements of major maize production countries. It will help China's corn to participate in international market competition.
The factor that affects the bulk density of corn is mainly moisture. With the same temperature and temperature of the same sample, as the moisture content of the corn decreases, the bulk density value gradually increases, and even some changes the grade. According to the analysis of a large number of tests and survey results, due to the influence of corn variety and origin, the regularity of the change in bulk density of the same maize sample with the decrease of water content is not obvious. In particular, there is no linear relationship between corn bulk density exceeding 23% moisture. During the inspection process, it was found that there was a certain error in the bulk density measured by the 18%-23% corn supplemented bulk density method. Therefore, China's current maize standards canceled the supplementary bulk density based on the 18% moisture content and the moisture content. For every one percentage point increase, the bulk density increases by 5 grams per liter.
In addition to measuring the bulk density of corn, electronic load receptors can also analyze the quality of wheat and rice sorghum and other crops. Container weight is an indispensable instrument in the processing industry. The load cell produced by Top Instruments has a charging function, and Internal SMD components replace traditional electronic components and are more accurate.
The bulk density of a substance generally refers to the weight of an object within a unit volume. Generally, the higher the weight, the greater the density. The bulk density of a measured substance is generally measured by a bulkhead. When a food processing plant processes a raw grain, it generally tests the quality of the raw grain. At this time, a bulk density device can be used for measurement and analysis, and there are many factors that affect the bulk density of the substance.
