[0032] Preliminary preparations: Prepare sample carriers 3 and place them on electronic balance 8 for weighing. Sample carrier identification device 2 identifies sample carrier 3 and transmits information about sample carrier 3 to computer 11 for recording. Electronic balance 8 transmits mass data of sample carrier 3 to computer 11 for recording. The information and mass data of each sample carrier 3 are bound and stored in computer 11 in a one-to-one correspondence. The empty mass m1, m2, m3, etc. of each sample carrier 3 is obtained.
[0033] In the first step, the user takes a sample to be tested with a fixed ring knife volume of V, and places the sample (with the barcode or QR code with sample information facing upwards) on the electronic balance 8. The sample identification device 4 above transmits the identified sample information and the weighing data of the electronic balance 8 to the computer 11 to obtain the mass m of the sample to be tested. 样 , the data information received and processed by the computer 11 during the subsequent test process are all registered under the sample information.
[0034] In the second step, after the system has collected the sample number, it automatically allocates two sample carriers 3 from the sample tray 1. The first sample carrier 3 is driven by the sampler 5 through the sample carrier identification device 2 to the electronic balance 8. The system automatically records the RFID code of the sample carrier 3 and the weight m1 of the empty sample carrier 3. The user takes a portion of the sample according to the test requirements and places it in the sample carrier 3.

[0036] Step 3: For the second sample carrier, the operation steps are the same as step 2. The weight m2 of the empty sample carrier 3 and the mass m of the partial sample and the sample carrier 3 are obtained. 2-湿 .
[0037] Step 4: Dry the two sample carriers 3 loaded with part of the sample together with the sample tray.
[0038] Step 5: Place the two sample carriers 3 together with the loaded dried samples and perform the following operations in sequence.
[0039] Place the two sample carriers 3 loaded with partial samples, along with the sample tray, at the designated location on the left side of the operating table. The sample carriers 3 are identified by the sampler 5 as they pass through the sample carrier identification device 2. The information about the sample carriers 3 is transmitted to the computer 11. After the sample carriers 3 reach the electronic balance 8, the electronic balance 8 transmits the mass data of the sample carriers 3 and the loaded dried samples to the computer 11. The mass m of the dried sample and the sample carriers 3 is obtained. 1-干 、m 2-干 After that, the system automatically sends the tested sample carrier to the sample tray on the right.

[0041] According to the test requirements, we can get:
[0042] Wet density of the sample ρ = m 样 / V,m 样 is the sample mass obtained in the first step, and V represents the sample volume.
[0043] The moisture content of the sample taken for the first time is w1=[(m 1-湿 / m 1-干 )-1]×100%
[0044] The moisture content of the second sample w2=[(m 2-湿 / m 2-干 )-1]×100%
[0045] Sample evaluation moisture content w = (w1 + w2) / 2
[0046] Dry density of the sample ρ d =ρ / (1+0.01w)
