Clarity analysis is the determination of the percentage by weight of the different components (net seeds, other plant seeds, and impurities) of the test sample and the characteristics of the sample mixture, and the composition of the seed batch is deduced accordingly. The purpose is to understand the weight ratio of the three components of net seed, other plant seeds and impurities in the seed batch, so as to provide the basis for seed quality classification. Seed clarity is one of the parameters of seed quality, in addition to seed weight, seed water content, and germination rate. Seed grading requires the determination of each parameter and the final classification. Moreover, each parameter at a level must meet the requirements before it can be classified as this level.
Stitch bonding machine is a type of textile machinery used to create non-woven fabrics. It works by mechanically interlocking fibers together using a series of needles and threads. The machine can produce fabrics with a variety of textures and properties, such as thickness, elasticity, and strength. Stitch bonding machines are commonly used in the production of clothing, upholstery, and automotive textiles. They are also used in the medical industry to create wound dressings, bandages, and other medical textiles.

The earliest farmland operations were basically done by hand. At that time, the seed's net degree had no significant impact on the crop's output. As long as the seeds were cleared, raised, or picked, they could work; but with the With the increasing popularity of sowing seeds, the seeds have higher and higher requirements for cleanliness. Seeds with low cleanliness are prone to cutting seedlings and crop yields are greatly affected. At this time, a suitable seed cleanness table can greatly improve the seed's clarity.
There are several methods for seed clarity: use wind power or use optical instruments. Wind power was the earliest use, but now there are instruments similar to the seed winnower on the market. They use the size of the wind to clean the seeds. Because the weight of a pure seed is heavier than the weight of those impurities or alum, the seeds can be roughly classified. However, the most widely used and most used is the seed clarity analysis platform. Seed clarity analysis platform is based on the principles of optical transmission, reflection and amplification, combined with electronic technology and ergonomic principles. The instrument is composed of three parts: a transmission light source system, a console, a reflective light source and an amplifying device. The clarification of the seed clarity can be performed in detail. Seed clarity test table soft white surface, uniform reflection, the overall lightweight, placed on the desktop, you can enlarge the observation of the measured object, show its excellent performance in the seed cleaning, clarity testing, and now, has been widely used in Various agricultural institutions, seed companies, seed management stations, food agencies, and other related institutions have used this as the designated instrument for the analysis of seed clarity, and have achieved consistent favorable comments.
