Seed processing is the further processing of field seeds, and once the purity reaches over 90%, it becomes more commercialized. Among them, removing various pollutants from seed materials is an important step in the commercialization of seed processing. Usually, please refer to the following principles.
1. If the removal weight of high-quality seeds is significantly smaller than that of high-quality seeds, and the size is significantly different from that of high-quality seeds, then machines with specific seed weights should be prioritized. This machine is currently widely used.
2. If there is a significant difference in the length and size of the cleaning, and there are still long or short contaminants present, and the contaminants cannot be removed after gas screening treatment, a hole cleaning machine should be used.
3. After treatment with air screens and hole cleaning machines, the cleanliness has been significantly improved, and the particle size is relatively uniform. However, there are still some dry grains, worms, and ear mold kernels in corn, and some dry grains, worms, and shell kernels in wheat. Dry grains, powdery mildew, rice germination, insecticidal diseases, and pathogenic bacteria in beans. Most of the above impurities are density impurities (specific gravity), and their weight is usually higher or even heavier than elite species. If there is no specific weight washing machine, it cannot be disassembled. With the development of the seed industry, proportional cleaning machines have become increasingly popular, and their operation is more difficult than air filter cleaning machines.
Of course, before cleaning, some seeds need to be threshed, sown, flipped up, polished, and removed. Therefore, it is necessary to purchase suitable processing machines. When handling corn seeds for ears, threshing and cleaning machines should be used. If rice is needed, it should be chosen.
The above is the scope and advantages of the seed density machine that the editor has shared with you. If you want to learn more, please follow the official website of Yongming Machinery.
