The amount of powder obtained at the end of the grinding process is about 400 g.
The purpose of performing raw material treatment on shrimp shell waste through cleaning,
grinding, and sieving is to extract high-quality chitin and chitosan.
By cleaning the waste, the impurities can be removed, and the subsequent grinding and sieving
processes can produce a purified and homogeneous material suitable for chitin and chitosan
extraction. This raw material treatment process ensures the production of high-quality chitin
and chitosan with optimal purity, which can then be utilized in various applications.
