2022-04-20
Crystalline sorbitol is an important fine chemical product that can be used in the production of vitamin C, pharmaceutical additives, anti-crystallizing agents, hygroscopic agents and other products, and is widely used in chemical, pharmaceutical, tobacco and other industries. Crystalline sorbitol is produced by crystallization technology, so what is the specific preparation process?

  The VC grade liquid sorbitol is evaporated and concentrated to a molten state with a solid mass concentration of more than 98%, cooled to 105-120 ° C, sprayed on the boiling sorbitol crystal seed, and stirred and mixed while spraying to crystallize the molten sorbitol. γ? crystalline sorbitol is formed, wherein the mass ratio of molten sorbitol to sorbitol seed crystals is 1:2 to 2:1; after spraying, the obtained product is heat-insulated and matured, and then cooled to 20 to 40° C. After pulverization; spray with clean steam after pulverization, and obtain finished crystalline sorbitol after drying.
