In food quality testing, grain screening and bulk density determination are among the most important test items. Bulk density measurement can generally be done using a bulkhead. Food screening can also be done using instruments. We recommend using a DSX computer filter. The instrument is a special instrument developed for the screening of grain impurities. Its standard complies with the national standard of GB5494-85 "Inspection of Impurities and Imperfect Grains of Foodstuffs and Oils". It is a new standard instrument product and the use of DSX computer filter can be quickly and accurately. The completion of grain and oil screening tests is an ideal choice for the classification of agricultural breeding sieving.
The traditional food impurity screening method is to use a hand-sieving method, that is, to nest the sieve layer, pour the sample, and after covering the sieve lid, place the sieve on a glass plate or a smooth tabletop with hands at a rate of 110 per minute. ~ 120 times the speed, according to the clockwise and counterclockwise direction of the screen movement 1min, while the scope of the screen, grasp in the selection of sieve diameter to expand 8 ~ 10cm. Although it is very simple to say, it is actually very difficult to operate. It requires the operator to have a wealth of experience and professionalism. Even so, manual screening is still difficult to achieve full accuracy and uniformity, so the measurement results will often vary from person to person, with actual results biased. But if you let the screening work use electric screening, the results will be completely different.
The DSX computer filter is a professional instrument that uses an electric screening method. The advantage of electric screening is that as long as the setting is set, the instrument will automatically complete the screening according to the set requirements of the program, with almost no deviation. For example, the sieve is automatically sieved left and right for 1 minute and 110 to 120 revolutions per minute. From a practical point of view, the screening effect of the DSX computer filter is also very good. It not only solves the problem of manual screening, but also improves the efficiency and accuracy of the screening. Therefore, for screening of grain impurities, we recommend the DSX computer filter.
