Preparation method for stored water or water solution dewatering composite capsule for cigarettes

The invention discloses a preparation method for stored water or water solution dewatering composite capsules for cigarettes. The preparation method for the stored water or water solution dewatering composite capsules for the cigarettes comprises the following steps of 1, preparing water or a water solution with water-soluble components and thickening agent dissolved therein; 2, preparing an inner soft capsule wall material capsule solution or prefabricated wall material capsule pieces; 3, preparing inner layer soft capsules directly wrapping water or the water solution through a soft capsule conventional method and performing shaping after volatilizing the solvent; 4, after the inner soft capsule is in swelling equilibrium for a certain time, solidifying through coating macromolecule paint or coating, then forming outer layer dense protective films or layers and preparing the stored water or water solution dewatering composite capsules. The preparation method for the stored water or water solution dewatering composite capsules for the cigarettes is simple, safe and controllable, meanwhile, the isolation effect of the stored water or the water solution is remarkably improved, and the service life of the stored water capsules for the cigarettes is effectively prolonged.
