The importance of seed clarity and the introduction of professional instruments Seed clarity is also referred to as cleanliness. Seed clarity refers to the percentage of normal seed weight in the total weight (contains impurities other than normal seeds) in a given amount of seed. A 100% clarity indicates that the seed has no impurities. Seed clarity is one of the important indexes for judging the quality of seeds, and it is an important basis for seed grading and seeding rate determination. It has important significance in agricultural production, while seeds with low cleanliness in agriculture have great impact on agricultural production. The impact is mainly manifested in several aspects: firstly, increasing the seeding rate of seeds and reducing the utilization rate of seeds; secondly, affecting the growth and development of crops; thirdly, sowing seeds with high moisture content will affect the storage and transportation of seeds. The test of the seed's clarity can be done using a blast cleanness meter or using a seed cleanness workbench. Here's a simple look at the difference between the two.
The blast purity meter and the seed clarity table are two types of cleanliness instruments developed from different design concepts. The blast type purity meter is a concept developed using wind mechanics, because seeds There is a certain difference between the weight and the weight of the impurity. The seed is separated from the impurity by the action of the wind force. At the same time, the instrument can adjust the wind force according to the size of the seed particle, and make it suitable for all the test of the seed's clarity.
The Seed Clarity Workbench is based on the principles of optical transmission, reflection and amplification combined with electronic technology and ergonomic principles. This instrument is characterized by the ability to zoom in and reflect, allowing us to observe the seed epidermis more closely and to further ensure seed clarity. During the research and design of this form, the instrument was reformed many times, and finally its design was more humanized, mainly reflected in the following points: The two sides of the work table were adopted according to ergonomic principles. Slope design, comfortable and effortless operation; the lower part of the instrument is equipped with a drawer to store the selected seed; the left and right side of the net degree table is designed with a protruding edge to prevent side leakage of the seed; the glass table can be withdrawn and the lamp tube can be replaced; The seed hole is provided to facilitate the selection of the seed removed; the wooden structure, the ultra-thin observation platform, and the additional desktop illumination magnifier.
Regardless of whether it is a blast-type cleaner or a seed-clarity workstation, both models are professional seed cleaners, but personally feel that the use of the two models will be even better, first through the use of blast-type clarity. The instrument separates the initial separation of the seed and the impurities, and uses the seed clarity table to observe the epidermis of the seed, which not only saves time, but also enables more accurate judgment of the seed's clarity.
