About granulation. By themselves, dry powder particles do not form into granules. The powder should be moistened with a liquid with a binder added to it. It can be powdered sugar, an aqueous solution of gelatin and a bunch of other substances that ensures the gluing of particles together. That is, you need to take a powder and some liquid with a bonding agent. Then you need to gradually inject this liquid into the powder through the sprayer, while stirring. Then the moistened mass needs to be granulated.
