 
Edible salt, chemically known as sodium chloride (NaCl), is one of the most common and essential seasonings in daily life. It also serves as an important raw material in the food processing, chemical, pharmaceutical, and feed industries.
Depending on its origin, edible salt can be classified into sea salt, well salt, rock salt, and lake salt.
During salt production, processes such as crushing, screening, drying, iodizing, and packaging are required. Among them, screening is a key step to ensure uniform particle size and high purity.
Because salt crystals are hard and hygroscopic, the screening equipment must be corrosion-resistant, moisture-proof, and designed to prevent screen blockage. Equipment made of stainless steel 304 or 316L is widely used to meet hygiene and durability standards.
Sanyuantang Machinery provides efficient, sanitary, and reliable screening solutions for edible salt processing, helping customers produce high-quality, food-grade salt that meets international standards.
