Abstract
A method for producing granules of a uniform size includes preparing an organic member solution, uniformly dispersing an inorganic member in the organic member solution at a weight ratio of 1 to 10 based on an organic member to form an organic-inorganic composite solution, spraying the organic-inorganic composite solution in an electrostatic charge manner, and polymerizing the sprayed organic-inorganic composite solution to form a hydrogel phase. The granules having a uniform size may be mass-produced in a short time and may be produced at a high yield. The method may be applied to a variety of fields, such as a pharmaceutical field, a medical field, a cosmetics field, and a food field and may replace a conventional spray drying method.
