What are the two production processes for sodium metabisulphite?
Sodium metabisulphite is a common additive used in food processing and manufacturing. It is also used as a disinfectant and antimicrobial agent. The solid form of Sodium metabisulfite is white, crystalline, or powdery, and it has a faint sulfur scent. toxic when breathed in. irritates skin and tissue severely. Noncombustible, but when heated to a high temperature, it may break down and release deadly sulfur and salt oxide gases. When combined with water, a corrosive acid. both a laboratory reagent and a food preservative. In this article, we will discuss the two production processes for Sodium metabisulfite.
Sodium Metabisulphite Production Process
There are two production processes for sodium metabisulphite: the anhydrous process and the mixed anhydrous-crystalline process. The anhydrous process is more common, as it is easier and cheaper to produce.
The anhydrous process begins by heating sodium metabisulphite powder to around 800 degrees Celsius. This high temperature breaks down the sodium metabisulphite into its component molecules, which then form sodium sulfate crystals. These crystals are then poured into molds and allowed to cool. Once they have cooled, the sodium sulfate crystals are broken up into smaller pieces and the resulting powder is called sodium metabisulphite anhydrous.
The mixed anhydrous-crystalline process is similar to the anhydrous process, but instead of using a heat source, crystals are grown in a cold environment. This process is used to produce high-quality sodium metabisulphite that does not contain any impurities.

Sulphite Processes
Two production processes for sodium metabisulphite are the wet process and the dry process. The wet process is the more commonly used production process because it is cheaper and faster. The wet process involves spraying sulfite solution into the air to form an aerosol. The Sodium Sulfite and Sodium Formate solution than meets with moisture in the air and reacts, creating sulfur dioxide and hydrogen gas. This gas mixture is then captured and condensed into liquid form. The dry process is less common, but is considered more environmentally friendly because it does not involve using chemicals or water. The dry process instead involves heating sulfur dioxide and hydrogen gas until they form a solid, which can then be used to produce sodium metabisulphite.
