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
The invention belongs to cigarette capsule preparing technical field, be specifically related to a kind of preparation method of cigarette composite package capsule.
Background technology
In cigarette mainstream flue gas, moisture content has important impact to Sensory Quality of Cigarette, improves moisture content of flue gas adopting, effectively can promote the comfortableness of flue gas and reduce its excitement.In cigarette mainstream flue gas, a moisture part derives from products of combustion, and a part derives from the water-content of cigarette own.Cigarette burning produces moisture and generally fluctuates less; The moisture content of cigarette own is determined by complete processing and condition of storage, promotes moisture content and reduces its processing characteristics, easily cause going mouldy of cigarette simultaneously.Conventional cigarette technology, mainly through means such as humectation moisturizings, to keep moisture content in main flume, reduces the disadvantageous effects such as environmental drying.Therefore improve moisture content in main flume at present, apply mainly through outer source apparatus, as duroplasts capsule water storage in external water pipe or external filter tip etc.But because human consumer need additionally purchase, do not meet the suction custom of most consumers, thus its practical application is not extensive simultaneously.
In cigarette filter rod, embedding moisture soft capsule, by racking capsule release moisture before suction, can solve the problems referred to above.The preparation of soft capsule mainly contains dropping method, orifice method and pressing, can form the soft capsule of different size, specification according to technology controlling and process, is mainly spherical, droplet shape or cylindricality, can play stable parcel, the isolated effect being wrapped composition.But because the current main application of soft capsule is packaging medicine composition, must be dissolved in gastric juice while composition safety, decompose completely or digestion.In order to realize such use, main raw material prepared by soft capsule wall material is the hydrophilic natural macromolecule materials such as gelatin, and it meets water significantly swelling or dissolving, thus destroys soft capsule structure, therefore can only wrapping up oiliness or solid matter, having a definite limitation to being wrapped material moisture content simultaneously.
The technology that current cigarette soft capsule directly wraps up water has more research.But being subject to the restriction of soft capsule forming technique, soft capsule directly wraps up the actual effect that water does not still reach long-term water storage.This is because soft capsule is shaped mainly through solvent evaporates, solvent molecule volatilization leaves a large amount of microvoid structures.Although barometric point effect prevents oozing out of liquid water, due under capillary structure, the curved surface saturated vapor pressure of water is greater than extraneous water saturation and increases air pressure, the continuous loss through volatilization of water molecules.Therefore existing cigarette soft capsule technology, under the prerequisite not using high compactness material, is difficult to solve this technical barrier of long-time water storage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of internal layer soft capsule that can realize to the direct parcel of water or the aqueous solution and moulding, stops penetration by liquid water; The preparation method of the cigarette composite package capsule that first the lower internal layer soft capsule of external force extruding simultaneously breaks.
For solving the problem, the present invention adopts following technical scheme:
A preparation method for cigarette composite package capsule, comprises the following steps:
1) preparation is dissolved with water or the aqueous solution of water soluble component and thickening material;
2) not exclusively water-soluble amphipathic natural macromolecular material internal layer soft capsule wall material glue or prefabricated wall material film is prepared;
3) by preparing the ordinary method of soft capsule, the internal layer soft capsule of water or the aqueous solution is directly wrapped up in preparation;
4) after internal layer soft capsule is shaped, under certain air pressure, directly by the heat-seal of layer high molecule mould material, composite package capsule is prepared.
Further, in step 4) in, described layer high molecule mould material is polyethylene or polypropylene.
Further, in step 4) in, described heat-seal procedure of processing is, heat-sealing regional temperature be 200 ± 20 DEG C, heat seal width is 0.5-1mm, and heat-sealing pressure is under the condition of 350-500KPa, cuts after heat-sealing cooling, sealing and cutting spacing is 3.5mm, and pressure is 1.2-1.5 times of normal atmosphere.
Further, in step 4) in, the packed size of described composite package capsule is less than filter stick cross section, and length is filter lengths 1/3 to 1/4.
Further, composite package capsule is embedded in filter stick, prepares cigarette, and by racking composite package capsule release water and water soluble component, flue gas is regulated.
Outer protective layer of the present invention uses multilayered polymer film heat-seal; solve water molecules volatilization and infiltration problem; the present invention distinguishes one of feature of other multilayered polymer film heat-seal technology and is: set by heat-sealing region and temperature; and wrap up certain pressure air and internal layer soft capsule simultaneously, reach encapsulated bond position 6-8KPa ruptures at pressures.
Designed by technique scheme, realize composite package capsule and directly wrap up water or the aqueous solution, and stably stored water or the aqueous solution; When external force physical impact, first internal layer soft capsule breaks, under continuous and under internal pressurization air effect, the heat-seal bond broken of outer membrane, thus reach the object of release water and the aqueous solution, embedding composite package capsule in filter stick, discharging wherein moisture or water-soluble flavor matter by racking, thus move in main flume, realize the application regulating moisture or improve water-soluble flavor matter blending effect.
The invention has the beneficial effects as follows: internal layer soft capsule uses amphipathic natural macromolecular material, solve bag water or aqueous solution soft capsule preliminary shaping and safety problem, hydrophilic natural high score material to water or the aqueous solution too much swelling, moisture or water soluble component are bound by hydrophilic natural high score material inner layer soft capsule, do not reach the effect racking rear release; Hydrophobicity natural macromolecular material uses other non-aqueous solvents, and application is subject to a definite limitation.Comprehensive above-mentioned practical application effect, the present invention uses amphipathic natural macromolecular material, plays water or the moulding effect of the aqueous solution, the process of stable formation after its water balance, can carry out, shorten process period after multilayered polymer film encapsulation.
