According to the provisions of Article 2.3.6.1 of GB6970, samples shall be taken from the materials before and after drying. For continuous dryers, samples shall be collected three times from the materials discharged from the machine. Each sampling shall be for 2 to 3 minutes. The interval between samples shall be no less than 5 minutes. A 2kg small sample shall be collected each time. b. 10 samples shall be collected at different positions and at different times on the cross section of the feed inlet and discharge outlet of the dryer (for fixed bed dryers, samples shall be collected at different positions on the bed surface). The amount of each sample shall be no less than 150g. c. The above samples shall be divided into average samples and quantitative samples according to GB3543, GB2930 and GB2772. 4.3.1.2 Performance measurement and index calculation.

4.3.2.1 Sampling
a. Sampling position. Sampling should be taken at the original material feeding port, all impurity discharge ports and the main discharge port of the last process at the same time. If there is no sampling condition at a certain place, the materials discharged during the entire operation time can also be weighed and samples can be taken from them. b. Sampling time. The first sample should be taken 5~10 minutes after the operation is stable and the finished product is discharged. Samples should be taken twice every 5~10 minutes thereafter, and the sampling time should not be less than 5s each time. The amount of sample taken from the main discharge port of the last process each time should not be less than 2000g. c. Weigh all the samples collected and record them in Table 6. According to the provisions of GB3543, GB2930 and GB2772, the samples collected from the feeding port and the main discharge port of the last process are divided into two average samples and three quantitative samples. When determining the content of weed seeds that harm crops by the number of grains, the remaining samples (i.e. the remaining part of the average sample after the quantitative sample is used) should be measured separately. 4.3.2.2 Performance measurement and index calculation, the results are recorded in Table 6. a. Moisture content (water content), purity and germination rate are measured for samples before and after cleaning according to the provisions of GB3542, GB2930 and GB2772. However, when determining the germination rate, whether the samples are before or after selection, as long as they are grains of this crop, they are within the range of random sampling. Purity is calculated according to formula (6).
