Summary of the products
The Vc direct pressed granules and Coated Vitamin C series products are widely used in Medicine, food and feed stuff etc.
Vc granules have good condensability, so can be made into smaller and high content ascorbic tablet with adding less shaping agent; since less shaping agent used, the produced ascorbic acid tablet has better stability of its colcor; since it has good fluidity, and can get better evenness n content without adding other shaping agent so the production process becomes simper, which can save the operating hours and slow down the equipment abrasion and energy consumption.
Coated Vitamin C has better stability than common Vc in high temperature, water and minerals.
Application
Vc granules series: applied in the press of Vc tablet for adsorption or chewing, and for compound vitamins directly pressing and the troche of vitamin minerals.
Coated Vitamin C: A-type coating suits for medicine tablet pressing, F-type suits for aquatic product fowl and livestock premixed feed stuff additives.
