The Technology Of Magnesium Sulfate Food Grade
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.
