摘要： A method for continuously preparing stable-type vitamin A microcapsules is disclosed. The method comprises the following steps: adding vitamin A crystals and an antioxidant into a crystal melter continuously according to a certain ratio under the protection of nitrogen to prepare vitamin A melting oil containing the antioxidant; pumping the above melting oil into a high gravity rotary packed bed emulsifier with a liquid distributor by a pump, and pumping aqueous solution containing gellable modified starch into the above high gravity rotary packed bed emulsifier after deoxidation treatment to obtain vitamin A emulsion at the outlet of the high gravity rotary packed bed emulsifier; and atomizing and spraying the emulsion continuously in a cooled starch bed for granulating, and performing fluidization drying and gelation treatment in a fluidized bed by taking nitrogen as a drying medium to obtain the stable-type vitamin A microcapsules. Above method has the advantage of capability of continuous production, and has good embedding effect due to adopting the gellable modified starch, granulating and gelation treatment, thus the product has good storage stability.
