The Application of the Blow-type Cleanness Meter in the Analysis of Seed Clarity

Seed clarity analysis Objective: Through the analysis of the three components of crop net seeds, other plant seeds and impurities, understand the true weight of clean use available in the seed lot and the types and contents of other plant seeds and inanimate impurities, in order to evaluate the seed quality. Provides the basis.

Correct identification of heavy-duty hybrids in crop seeds Heavy-duty hybrids are those that are significantly different in quality or size from the tested seeds, such as clods, small stones, and so on. This can summarize the characteristics of heavy-duty hybrids: the volume or weight is significantly different from the tested seeds; the clarity analysis results have been seriously affected. Therefore, we must eliminate the heavy-duty mixture before the clarity analysis. On the one hand, it may block the sampler. On the other hand, the clarity analysis results have obvious deviations, affecting the reputation of the company or the interests of consumers.

Reasonable selection of blast type netness meter
FJ-1 Purity Cleanness Tester introduces and refers to the technology of similar products in the United States and other countries, and uses electronic control technology to develop a special test instrument for the purity of seeds. It has functions such as continuously adjustable wind speed and timing. , Widen the scope of use of the instrument, improve the test accuracy, to meet the needs of a variety of seed and grain cleanliness test.

Seriously separate, analyze, identify, and calculate the results. After the blast-type cleanness meter operation method steps, we obtained net seeds, other plant seeds, and impurities. The three seeds were individually filled into containers and weighed using a balance. Then calculate the corresponding values ​​according to the following steps: (1) Calculate the sum of the weights of the three components of the net seed, other plant seeds, and impurities after the analysis; (2) Compare the sum of the weights of the three components with the weight of the original sample and check it. Whether the increase in material during the analysis exceeds 5% of the weight of the original sample, which exceeds the redo process; (3) Calculate the weight percentage of the three components. Calculate the sum of the weights of the three components as the denominator. Decimal, semi-sample calculation to two decimal places, the final result is one decimal place; (4) The final result of the three components retains a decimal place, the sum is 100.0%, less than 0.05% of the "micro", in the calculation Removed, the result is zero with "-0.0-" said. If the sum of the three components is 99.9% or 100.1%, increase or decrease 0.1% from the maximum component of the net seed component. If the rounding value is greater than 0.1%, check for errors in the calculations; (5) The test results for the netity analysis include the weight percentages of the three components of net seeds, other plant seeds, and impurities. When determining the weight percentage of a certain kind of impurity or a certain other plant seed reaching or exceeding 1.0%, the type should be indicated in the result report.
