The Technology Of Magnesium Sulfate Food Grade

by Hu Yanchao Magnesium oxide manufacturers in China

      Food grade magnesium sulfate has a large market in Europe, Japan and South Korea, and its price is much higher than that of industrial magnesium heptahydrate sulfate. Therefore, it is of great research value to process food-grade magnesium sulfate with industrial magnesium heptahydrate sulfate.

　　In China, there is no unified standard for food-grade magnesium sulfate, and most of the enterprises implement the pharmaceutical standard stipulated in the Chinese pharmacopoeia.

　　We take the 2000 edition of Chinese pharmacopoeia as the standard to carry out the experiment, take the magnesium sulfate of industrial heptachyhydrate as the raw material, produce the method of food grade magnesium sulfate: magnesium sulfate of industrial heptachyhydrate → dissolution → cooling crystallization → centrifugal separation → drying → product.

The results showed that the process conditions were: the dissolution temperature was 70℃~90℃, the relative density was 1.36g/cm^3~1.41g/cm^3, the recrystallization time was 7h~8h, the cooling rate was 2℃/h at the initial stage of crystal core formation, and the terminal temperature was 20℃~30℃.

Mei Shen is the world's leading producer of magnesium oxide,Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.

Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.

Hebei MeiShen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.

With rich experience in the research, development, production, management and operation of magnesium oxide products, MeiShen Group has always attached great importance to the research and development of new products and strict requirements on product quality.MeiShen has a high-level sales team.The business covers more than 20 countries and regions around the world.It is widely welcomed by new and old customers.
