The quality of the food grain in a certain volume is called the bulk density. Their units was g/L. The bulk density is a comprehensive indicator of food quality. Similar food, such as full grain, structure, bulk density; contrary bulk density is small. The bulk density is an important indicator of assessment of food quality which is good. The bulk density can be measured through the use of volume-weight tester which can simultaneous determination of bulk density value of the corn as well as wheat both food and thus also known as dual-use bulk density. This instrument is essential grain quality inspection agencies instrument. In the course of the operation it is an effective method to improve the life of the instrument. This article simply lists the electronic grain bulk density of points to note, as well as maintenance programs.

Points to note: To keep the instrument clean machine and parts. Cylinder capacity, grain tube, middle tube to be light-light, to prevent the collision and deformation. After weighing the capacity of the cylinder do not long hold on the pan. Do not use items outside the provisions of this electronic scales weighing bulk density. Non-professionals is strictly prohibited to disassemble the instrument.

Instrument maintenance: the instrument must be in accordance with the provisions on a regular basis test. When the instrument is long-term disabled, it should be in a dry, non-corrosive gas environment and save. Printer paper. Switch the instrument off, press the small button of the printer panel above, print the superstructure will automatically pop up, remove the waste paper tube, the new paper into the paper slot, and print the paper sheet of paper out of about 5cm, and then the printer cover press, you can fasten. Remove the waste tube, the new paper into the paper slot, and print paper sheet of paper out of about 5cm, then the top cover press, fasten to.
