| titleOfInvention | A kind of method for measuring the sand content of powdered grain |
| abstract | The present invention discloses a method for determining the sand content of powdered grains provided by the present invention, which is characterized by comprising the following steps: (1) ultrasonic vibration-assisted separation, (2) preliminary separation, (3) acid washing, ( 4) Dry weighing and calculating the sand content, the present invention solves the problems of improper stirring and difficult control in the previous national standard method of manually stirring with a glass rod, and is beneficial to the more uniform dispersion and classification of the particles in the sample in the liquid, It is conducive to the full separation and deposition of sand and dust. The straight funnel and latex tube are used to avoid the problem that the piston hole of the spherical funnel is prone to clogging, and it is easy to clean. The separation effect is good and the amount of carbon tetrachloride can be reduced. For special flours containing non-sand dust additives, the pickling step can be used to reduce the influence of additives in the flour on the measurement of sand content, which can greatly improve the accuracy of the measurement. |
