Abstract

The invention discloses a preparation method of composite encapsulation capsules for cigarettes. The method is specifically a composite encapsulation technique in which amphipathic natural high polymer materials directly wrap water or water solution to prepare inner-layer water-wrapping soft capsules, and the inner-layer soft capsules are subjected to thermal encapsulation with high-density multilayer polymeric membranes to isolate the inner-layer soft capsules from the external environment. The method aims to directly wrap the water or water solution with the composite encapsulation capsules and stably store the water or water solution; during external physical squeezing the inner-layer soft capsules break firstly, heat-seal joint parts of the outer membranes break under the action of continuous pressure and internal pressurization air, and accordingly the water and water solution is released. The stable formation process after water balance of the inner-layer water-wrapping soft capsules can be carried out after encapsulation of the multilayer polymeric membranes, so that processing time is shortened, and smoke moisture is increased remarkably by squeezing and breaking the composite encapsulation capsules in filter rods; meanwhile, the composite encapsulation capsules can be used for applying carriers to water-soluble components.

Description

technical field [0001] The invention belongs to the technical field of capsule preparation for cigarettes, and in particular relates to a method for preparing a composite packaging capsule for cigarettes. Background technique [0002] The moisture content in the mainstream smoke of cigarettes has an important impact on the sensory quality of cigarettes. Increasing the moisture content of smoke can effectively improve the comfort of smoke and reduce its irritation. Part of the moisture in the mainstream smoke of cigarettes comes from the combustion products, and part of it comes from the water content of the cigarette itself. The moisture produced by cigarette combustion generally fluctuates less; the moisture content of cigarettes is determined by the processing technology and storage conditions, increasing the moisture content reduces its processing performance, and it is easy to cause mildew in cigarettes. Conventional cigarette technology mainly uses methods such as mois...
