Problems solved by technology

In this method, due to the different specific gravity and viscosity of the inner and outer layer materials (core material and wall material), it is difficult to ensure that the core material in the liquid droplets formed in the air does not come out or lean in one direction, which seriously affects the prepared capsules. Excellent mechanical strength, roundness, uniformity, and post-processing performance
[0006] Ordinary soft capsule droplet method can not solve the mechanical strength, compactness and smoke tolerance of the shell, but also solve the reasonable crushing strength of the controlled release Problem (Zhang Wenhui, Chinese Patent Publication No. CN 101564667A)

Abstract

The invention relates to a preparation method of controlled-release soft capsules for cigarettes. The preparation method comprises the following steps of: dripping an oil-in-water emulsion containing polyvalent metal ions into a film former complex colloid solution as a template, enabling the periphery of the liquid drop template of the oil-in-water emulsion containing the polyvalent metal ions to perform self-assembly on the surface of the liquid drop template in the film former colloid solution through film former colloid particles to form an ordered spherical gel wrapping layer, further cross-linking through the chemical action of the colloid particles and the polyvalent metal ions in the emulsion drops to form a dense and firm film, forming primary products of the soft capsules, and further performing dyeing, drying and dehydration to obtain target capsules. The preparation method disclosed by the invention has the advantages of sufficient mechanical strength and dense structure, higher uniformity, roundness and stability of the capsules in comparison with the ordinary capsules, and great compatibility with smoke gas.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to a method for preparing controlled-release soft capsules for cigarettes. Background technique [0002] In traditional cigarette production, various additives, such as flavors, fragrances and seasonings, are usually added to tobacco during tobacco processing to improve the quality of tobacco and the sensory quality of tobacco products. However, in the process of adding additives, due to the different physical and chemical properties of additives, for direct addition of certain additives, such as components with better volatility, such as highly volatile flavors and fragrances, they are easy to volatilize, which makes it difficult to apply; Some components cannot be applied effectively; for high residual components, it will bring "pollution" to the equipment and affect the production of other products. With the advancement of science and technology, various new additive applicat...
