Take a piece of wheat that has been cleaned up with impurities and add different quality sand to the wheat sample to make samples with gravel content of 00%, 06%, L2%, L8%, and 24%; add different qualities The wheat husk was mixed with the samples with the wheat husk content of 00%, 01%, 02%, 03%, 04%, 05%, 06%, and 07% respectively; adding wheat straw of different quality, the wheat straw content was Samples 00%, 02%, 04%, 06%, 08%, L0%, L2%, L4%. In the preparation of wheat samples, the impurities were mixed well with wheat, and the bulk density of each wheat sample utilized a wheat bulkhead. Measured five times, and then take the average value, analyze the measurement results.
There is a linear correlation between gravimetric weight and gravel, and the correlation coefficient is Q983} As the gravel increases, the bulk density gradually increases. This is mainly because: the porosity of wheat is very high, and some are as high as 35% to 45%}, When gravel is added, these tiny gravels will fill in the pores of the wheat, increasing the density of the wheat and increasing the bulk density.
There is a linear correlation between oat husk and bulk density, and the correlation coefficient is Q9878. With the increase of wheat hull content, the bulk density gradually decreases. This may be due to the fact that the husk is a fluffy body with a large surface area and a low density. It is easy to empty the wheat grain and reduce its density, ie, the quality of wheat per unit volume is reduced.
There is a linear correlation between the bulk density and wheat straw, and the correlation coefficient is a Q9881. The bulk density gradually decreases with the increase of wheat straw. This may be because the wheat straw mixed in the wheat will empty the wheat grain, and the wheat straw is hollow inside. It will greatly increase the porosity of wheat, thus greatly reducing the wheat density. When the wheat straw content is between 1}/o%1}/o, the volume weight decreases more, indicating that the greater the wheat straw content, the more obvious this overhead effect.
After analyzing the relationship between the bulk density of wheat and the impurities mentioned above, it can be concluded that the impact on bulk density is total impurity content, wheat straw, wheat husk and sandstone, among which the total impurity content has the largest impact on the bulk density, wheat straw, and wheat husk. After that, sand and gravel again.
Analysis of the Relationship between Wheat Bulk Density and Wheat Bulk Density and Impurities
The grain quality of grain in a certain container is the grain bulk density, and the bulk density value is an important test index of wheat quality quality. The size of the bulk density value can comprehensively reflect the characteristics and characteristics of grain size, quality, shape, uniformity, depth of abdomen, texture of endosperm, and powder yield. Grain maturity, fullness, and size uniformity are all important factors affecting its bulk density. However, there are many studies on grain bulk density, and there is a very significant positive correlation between wheat grain bulk density and protein content, sedimentation value and hardness. The bulk density and total starch content also show a significant positive correlation. The higher the grain moisture content, the lower the bulk density. The determination of the bulk density of wheat can be effectively measured using a wheat bulkhead.
