Description

Technical Field

[0001] The utility model relates to the technical field of rice screening, in particular to a portable screening device for rice detection. Background Art

[0002] With the development of modern society, the discharge of domestic sewage and the illegal use of pesticides and fertilizers containing heavy metal components have led to excessive heavy metal residues in some farmland soils. It is reported that during the growth process, rice can absorb and enrich heavy metals in the soil through its roots. The heavy metal residues in rice can cause serious harm to the human body. Therefore, efficient and accurate rice heavy metal detection is of great significance to ensuring food safety and improving the quality of agricultural products.

[0003] The traditional method of rice cultivation is cumbersome. When harvesting, weeds, rice leaves, straw, chaff and dust attached to the rice usually need to be separated before normal testing can be carried out. my country's national standard "GB / T5494-2019 Grain and Oil Inspection Grain and Oil Inspection of Impurities and Imperfect Grains" sets clear inspection standards for rice. Rice can be effectively screened to remove impurities and imperfect grains, thereby improving the quality and nutrition of rice. During the planting process, rice is affected by environmental factors such as light, temperature, soil nutrition and moisture, and there are certain differences in the quality of rice. High-quality and full grains often have higher quality and nutritional value than inferior grains. With the improvement of people's living standards, heavy metal residue detection and analysis of rice with high-quality grains provide a more accurate scientific basis for scientifically evaluating the safety of rice.

[0004] Traditional laboratory testing of rice is done by manually shaking the sieve to separate the rice sample from the impurities, which consumes a lot of manpower, has a low degree of automation, is inefficient, and may cause unstable test results. In addition, most of the rice separators currently sold on the market are too large and need to be connected to an indoor power source to use, which is inconvenient to carry and cannot meet the needs of field work.
