The classification of wheat determines its economic value. In China, the bulk density is the main criterion for determining the level of wheat, and it is also the main evaluation index of wheat quality. It is also an important basis for calculating the wheat flour yield rate. Wheat bulk density is affected by many external factors. The larger the bulk density, the better the grain development and the more endosperm. The rate of flour extraction directly affects the economic benefits of the flour mill. Therefore, the study of the relationship between the change in the bulk density of wheat and the rate of flour extraction is of great significance to flour production. The determination of the bulk density of wheat is generally measured by a bulkhead, which is an instrument commonly used internationally.
500g wheat samples were used to measure impurities, imperfect grains and moisture, water content was converted to 14% according to the original wheat moisture condition, and the wheat was hydrated at room temperature 25°C for 20 hours, and the person was started to grind, and the flour and chilled weight were weighed. Powder extraction rate. With 750 g/L as the standard bulk density, the standard weight removal rate was taken as an integer and expressed as 0, and the difference between the test weight and standard bulk density was tested. Can predict any number of changes in bulk density and chalking rate. Therefore, the standard weight-bearing rate of powder extraction is explored, and other arbitrary weight-bearing wheat can use the standard weight-recovery rate to calculate the actual weight-receiving rate. That is: the actual weight-rate extraction rate /% = the standard weight-density extraction rate / The difference between the actual powder yield and the standard weight difference caused by %.
Through the determination of the bulk density of wheat by the weight density device and the analysis of the wheat powdering situation, it can be concluded that the wheat flour extraction rate is positively related to the bulk density. From then on, under different conditions, the impact of the bulk density on the extraction rate is different; under the same conditions, the higher the bulk density of wheat, the higher the powder extraction rate. The weight of wheat at different stages has different effects on the extraction rate. Within the range of standard bulk density (7so}L soil and 4 sg/L, the specific gravity is less than ±1% of the powdered g/L extraction rate; in standard bulk density (7s0g/L). ) For persons outside the 4s age L range, the test weight is 10% for each 10 year old and the rate of powder extraction is 1%; outside the standard bulk density (7s0g/L) for the ssg/L range, the test weight is less than 1% for each person. 1%; according to the relationship between the rate of powder extraction and the weight of the curve can be estimated to any of the powder density of the bulk density.
The weight-receiver plays an important role in the analysis of the relationship between wheat flour extraction rate and the bulk density. Through this test, the relevant precautions for actual production of the flour processing plant are also very clear. The powder rate can be estimated based on the change in the bulk density. For product quality control, to ensure maximum efficiency.
