Bulk weight is one of the necessary inspection items for grain purchase. This product is based on the “Reference Standard†in LS/T3701-1993 “HA/HGT-1000 Grain Bulker†Standard and Standard and GB1353-2009 “Corn†New National Standard. Developed according to the requirements of grain weight. The product measures the bulk density of food and sets its grade through standard requirements, so it plays a key role in grain purchase, storage and processing.
It reflects the fullness of rice and corn kernels and is affected by moisture and impurities. Corn bulk density is now used as a basis for grading, replacing the past pure grain rate.
It is a special measuring tool for measuring grain grade. The bulk density is the weight per unit volume.
The weight of wheat and corn is the weight (grams) of one liter of wheat and corn under standard bulk load test.
Performance characteristics:
1. Considering the actual application and application to different working places, it is convenient for different users to carry and use. The country's first grain bulk density with "charging characteristics";
2. The product adopts high-density and high-reliability imported patch components to replace the traditional electronic component parts, so that the internal structure saves space for component installation;
3, using advanced electronic weighing technology and computer technology, to achieve automatic display of test results while displaying weighing results;
4. The mechanical part has been carefully selected and carefully processed, and the unique external color tone makes the appearance more novel and beautiful;
5. This product also has the features and advantages of simple operation, system setting, high precision and fast measurement.
Configuration instructions:
1. According to computer technology, it is divided into two types of grain electronic weights with and without printing;
2. According to the product charging design, it is divided into two grain electronic weights with and without charging;
3. According to the measurement products of grain electronic bulk loader, it is divided into three kinds of measuring instruments: small particles (30mm diameter hopper), large particles (40mm diameter hopper) and dual-purpose type;
use
Or, say, one liter is a unit volume. The weight of a liter of corn is called the bulk density of corn. The heavier the weight, the less corn kernels that represent the shells
Instructions:
It is important to start the inspection. The instrument is filled with the grain to be inspected. For example, if there are three packages, the longest package is filled, assembled and discharged into the next package, and the excess grain is separated by the blade shape. Pour it out and finally weigh it. It is the weight. .
Method for determining the bulk density of corn
A1 instruments and appliances
A1.1GHCS-1000 bulk loader (40mm diameter under the funnel).
A1.2 grain selection sieve: the upper sieve hole diameter is 12.0mm, and the lower sieve hole diameter is 3.0mm.
A2 sample preparation
Two samples of the average sample were separated from the original sample, and an average sample of about 1000 g was taken, and the sieve layer was set to be screened twice according to the provisions of A1.2. The sieve on the lower sieve was mixed and used as a sample for measuring the bulk density.
A3 bulk load installation and measurement
A3.1 Open the lid, take out all the parts, and select the funnel according to the type of grain.
A3.2 Place the heavy-duty cylinder with exhaust vents on the electronic scale and adjust the zero point when no-load.
A3.2 Remove the capacity, install the capacity cylinder on the base of the iron plate and put on the middle cylinder.
A3.4 Pour the prepared sample into the grain cylinder and fill it up. Then place the grain cylinder on the middle cylinder, open the funnel switch, let the corn fall freely, and close the funnel switch after all the samples fall into the volumetric cylinder through the intermediate cylinder. Hold the joint of the grain cylinder and the intermediate cylinder with your hand, insert the insert into the slot accurately, remove the grain cylinder in turn, pick up the intermediate cylinder and the volumetric cylinder, pour the excess specimen on the insert, and pull out the insert. , remove the iron plate base on the capacity cylinder, and place the capacity cylinder on the electronic scale for weighing. The double test allows the difference to be no more than 3g/L, and the average is the measurement result.
