Physiological changes in grain grains, as well as their processing and storage, are affected by moisture. High grain moisture content will cause it to be prone to heat and mildew. It is necessary to ensure proper processing of grain and food production with adequate moisture content. Free water is very unstable in the grains, which is very unfavorable for the safe storage of food. In general, the bulk density of the samples with full maturity, compact structure, small particles, and low water content is larger; on the contrary, the bulk density is relatively small. In particular, the moisture content in the grain affects the bulk density and generally has a negative linear relationship. This is mainly due to the fact that the proportion of water is smaller than the specific gravity of grain. At the same time, moisture also affects the grain size. Grains with large moisture contents are also large, and the mass per unit volume is small. According to the bulk density, the volume of a certain volume of grain piles and the storage capacity required for certain quality grain can be calculated. This has certain practical significance for the storage and transportation of grains. The bulk density of grain can be determined by using a dual-purpose load receptor commonly used internationally.
Through the determination of the bulk density of wheat by the dual-use weight-receiver and the analysis of its water content, it can be found that there is a negative correlation between the bulk density of wheat and the change of water content. The same wheat sample, the higher the water content, the lower the bulk density; the lower the moisture content. The higher the bulk density, especially when the moisture content of wheat varies between 12.00o-14.0%, the lower the bulk density is. When the moisture content exceeds 14.0% and then rises, the decrease in bulk density decreases. Different wheat varieties have different effects on water-containing weight. Between 12.000-140%, when the water content rises, the weight reduction of hard wheat is greater than that of mixed wheat.
There is a positive correlation between the hardness index of wheat and the change of water within a certain range. The same wheat sample, in the range of 12.5% ​​to 13.5%, the higher the moisture, the greater the hardness index; when the moisture exceeds 13.5% or 14.U, the hardness index no longer increases with the increase of moisture. This may be because as the moisture of wheat increases, the adhesion of the material in the crushing chamber of the hardness index tester increases, and the crushed wheat particles partially adhere to the cavity and the crushing chamber wall, and it is difficult to fall. In addition, the crushed particles on the screen are due to High moisture content, sticking together, and coarse particles, are not conducive to easy flow and passing through the screen, resulting in increased sample retention on the screen, which is reflected in a large hardness index value. When the moisture content was between 12% and 13%, the resistance to crushing hardness index was in line with the best sensitivity range.
The analysis of the bulk density, the water content, and the hardness index of the dual-use weight-receivers can be used to analyze the relationship among the three. The weight-to-weight ratio is negatively correlated with water, and the water and hardness are positively correlated. It can be seen that there is a negative correlation between the weight and hardness.
