Bulk weight refers to the weight per unit volume. It is generally used as a unit volume. Or, say, a liter is a unit volume. The weight of a liter of corn is called the weight of corn. The heavier the bulk density and the higher the quality, the less the pod-thin corn kernels are. Similar to the concept of 1000-grain weight, the fullness of the reaction material. Under certain moisture conditions, the higher the bulk density of corn, the better the quality. In addition, the classification of national corn is also divided according to the bulk density, and the bulk density of Grade 1 corn is 710 g/l.
Bulk density determination: Corn bulk density determination depends on corn bulk density (diameter of the bottom of the funnel is 40mm); grain selection sieve: the upper sieve diameter is 12.0mm, and the lower sieve diameter is 3.0mm. Sample Preparation: From the original sample splitter to divide the average sample of two, take an average sample of about 1000g, according to A1.2 provisions of the sieve layer twice for screening. The mesh of the lower sieve is mixed and used as a sample for determining the bulk density. Electronic load cell installation and measurement: 1. Open the lid, remove all parts and select the funnel according to grain type. 2. Place the container with exhaust port on the electronic scale and adjust the zero point at no load. 3. Remove the capacity, install the capacity cylinder on the iron plate base, and put on the middle cylinder. 4. Pour the prepared sample into the cereal cylinder and fill it with a flat surface. Then put the cereal tube on the middle tube, open the funnel switch, let the corn fall freely, wait until the sample all goes through the middle tube and fall into the capacity tube, close the funnel switch. Grasp the whole position of the cereal tube and the intermediate tube by hand, insert the insert into the notch groove accurately, remove the cereal tube one by one, pick up the intermediate tube and the capacity tube, then pour the excess sample on the insert and pull out the insert. Remove the iron plate base on the capacity cylinder and weigh the capacity cylinder on an electronic scale. The allowable difference between the two tests is not more than 3g/L, and the average value is the measurement result.
The bulk density of corn plays a very important role in the process of ranking the corn. Therefore, the load receptor has received such attention. In addition, the wheat and other crops also need to determine its bulk density, and the wheat bulk density is also called the wheat bulk density.
