Description
FIELD OF THE INVENTION
[0001] The present invention relates to a cooling filter rod, an
application thereof and a cigarette, belonging to the technical
field of cigarette production.
BACKGROUND OF THE INVENTION
[0002] In the smoking process of traditional cigarette, the heat
generated by a cigarette burning cone will be carried by mainstream
smoke to a filter, and as the smoking progresses, the temperature
of smoke passing through the filter gradually increases. Studies
have shown that the temperature of the smoke at the filter can be
as high as 70-80.degree. C. near the end of smoking. Too high
temperature at the filter will affect the retention effect of the
filter, and will also affect consumer's evaluation on the sensory
quality of smoke. Therefore, it is necessary to appropriately
reduce the temperature of smoke. A heat-not-burn cigarette produces
smoke by heating the tobacco product with an external heating
element. Generally, the tobacco product reaches an atomization
condition at 250-350.degree. C. In order to ensure the amount of
smoke, low or no adsorption is usually required at the filter. The
temperature of high-temperature atomized smoke entering the mouth
through the filter will be higher than that of traditional
cigarette burning. Therefore, appropriate reduction of the
temperature of smoke is also a key technology for the development
of low-temperature cigarettes. Chinese patent CN201510045745.4
provides a filter and a cigarette. The temperature of smoke is
reduced by adding a phase change material to the filter, the phase
change material used is a mixture of a hydrated inorganic salt and
urea, and the mixture is sprayed onto a cellulose acetate rod or
its crystal is placed between two filters. As known in the
industry, the use and effect of this hydrated salt are not ideal.
Chinese patent CN101396173 provides a vortex cooling and flavor
keeping method for a cigarette and a cigarette structure. Vortex
channels are formed in front of a cigarette filter to achieve the
same cooling effect as air, but the structure is complicated and
not suitable for heat-non-burning cigarette.
[0003] The perfuming treatment through the filter is generally in
the form of perfuming particles, perfuming threads or capsules. For
example, Chinese patent CN101390657 discloses a cigarette filter
rod with a function of mint sustained release and a production
process thereof. The perfuming means is to use cotton threads
impregnated with perfume, but it is difficult to achieve continuous
perfuming.
SUMMARY OF THE INVENTION
[0004] The technical problem to be solved by the present invention
is, when cigarettes (including traditional cigarettes and
heat-not-burn cigarettes) are smoked, the temperature of smoke
generated by combustion is relatively high, causing a burning
sensation in the mouth of consumers to affect the smoking
experience. In order to solve the above technical problem, the
technical solution of the present invention is as follows:
[0005] A cooling filter rod is mainly formed by cooling particles;
the cooling particle includes a particle body and a shell coated on
the particle body, and the shell/or the particle body contains a
phase change material.
[0006] In this way, the cooling particles used have a core-shell
structure, and the surface shells are distributed with the phase
change material, which has a cooling function. The cooling filter
rod can be obtained by molding of the cooling particles according
to the required shape; after the cooling particles are stacked in a
certain shape, the entire cooling filter rod formed has a loose and
porous structure; when the cooling filter rod is applied to a
cigarette product and high-temperature smoke passes through the
cooling filter rod, the smoke can pass smoothly; and on the other
hand, the high-temperature smoke has a large contact area with the
shells, so the cooling efficiency is high, a good cooling effect
can be achieved, and the experience of a smoker is improved.
[0007] Optionally, only the shell contains the phase change
material; optionally, only the particle body contains the phase
change material; optionally, both the shell and the particle body
contain the phase change material.
[0008] In some embodiments of the present invention, the shell is
composed of a phase change material.
[0009] Further, the phase change material includes at least one of
PLA, polyethylene glycol, stearic acid, palmitic acid, paraffin,
microcrystalline wax, EVA, pentaerythritol, stearate-isopropanol
ester, and stearate-glycerol ester. The suitable phase change
material can ensure a good cooling effect while ensuring the
coating effect, thereby improving the overall cooling performance
of the cooling filter rod. Preferably, the phase change material
includes a mixture of PLA, polyethylene glycol, stearates
(including series stearates) and EVA.
[0010] In some embodiments of the present invention, the shell
further contains a flavor enhancer. In this way, the shell of the
cooling particle contains a phase change material and a flavor
enhancer, and after the cooling particles are stacked in a certain
shape, the entire cooling filter rod formed has a loose and porous
structure, and the smoke can pass smoothly; in addition, when the
cooling filter rod is applied to a cigarette product and
high-temperature smoke passes through the cooling filter rod, the
high-temperature smoke has a large contact area with the shells,
and the phase change material has a high absorption efficiency on
the heat of smoke, so the cooling efficiency is high, a good
cooling effect can be achieved, and the experience of a smoker is
improved; meanwhile, the flavor enhancer in the shells is heated to
slowly emit flavor, and the flavor enters the mouth of the smoker
together with the smoke to give the smoke a unique taste, which can
meet individual smoking needs; and when the phase change material
undergoes a phase change by absorbing heat, the flavor ingredients
inside the shell can be slowly released to add the flavor
continually. Generally, the volatilization of the flavor enhancer
to produce flavor is also a heat absorption process, and is also
beneficial to the reduction of smoke temperature.
[0011] Further, the flavor enhancer includes a flavor and/or a
tobacco extract; preferably, the mass ratio of the phase change
material to the flavor enhancer is 100: (0.5-10). Optionally, the
flavor includes at least one of menthone and coffee flavor, which
can be specifically selected as required, and other types of
flavors can also be selected as required.
[0012] Further, the mass of the shell accounts for 0.5-30% of the
total mass of the cooling particle, preferably 1-20%. The proper
amount of the phase change material can ensure that the cooling
effect meets the requirements, and channels of the filter rod will
not be blocked when the phase change is repeated in the smoking
process.
[0013] In some embodiments of the present invention, the particle
body contains plant fiber powder and/or inorganic material powder,
and further, the plant fiber powder and/or inorganic material
powder have a particle size of 80-200 meshes, preferably 100-180
meshes.
[0014] Further, the plant fiber powder includes at least one of
tobacco powder, corncob powder, rice husk powder, walnut shell
powder, coconut shell powder, tangerine peel powder, and grapefruit
peel powder. The plant powder is natural, pollution-free and cheap,
can be prepared into dense particles to reduce the adsorption
efficiency, is more suitable for low-temperature cigarettes, and
can reduce the loss of cutters during the preparation of the
cooling filter rod and cigarettes. Further, the inorganic material
powder includes at least one of calcium carbonate, carbon powder,
ceramics, silica gel, and molecular sieves. The use of inorganic
materials does not introduce peculiar smell, and at the same time,
the porous property is partially utilized, so that the cooling
filter rod has better adsorption performance and is more suitable
for ordinary cigarettes. Further, the particle body further
includes an auxiliary molding material, and the auxiliary molding
material includes at least one of a binder, a wetting agent, and an
excipient.
[0015] Further, the binder includes at least one of PVP, HPC, HPMC,
SCMC, and modified starch; the wetting agent includes water or
alcohol; and the excipient includes microcrystalline cellulose and
lactose. The suitable binder and wetting agent can ensure that the
prepared particles have good shape and strength.
[0016] By reasonably adjusting the ratio of the plant fiber powder
and the inorganic material powder, the adsorption performance of
the cooling filter rod can be adjusted to an appropriate range, and
the needs of different cigarettes can also be met.
[0017] In some embodiments of the present invention, the particle
body is obtained by thoroughly mixing base powder, hot melt
adhesive powder, excipients, and water, granulating, drying, and
sieving; wherein the base powder includes at least one of plant
materials, inorganic materials, and metal powder; further, the
plant materials include at least one of tobacco raw materials,
straw, peanut shells, bagasse, corncobs, pericarp, and aromatic
plants; the inorganic materials include at least one of carbon
powder, clay, calcium carbonate, and silicon oxide; and the metal
powder includes at least one of iron powder, aluminum oxide, and
copper powder. Generally, the ratio of base powder, hot melt
adhesive powder, excipients, and water can be selected according to
needs, as long as they can be used for normal and smooth
granulation and formation. The use of plant materials can reduce
costs as much as possible, and the aromatic plants also have a
flavoring effect in the filter rod. The inorganic materials and the
metal powder will not introduce peculiar smell, and the metal
powder is more helpful for the cooling effect. Further, the
aromatic plants include at least one of sandalwood, agarwood,
cloves, coffee, and anise.
[0018] Further, the hot melt adhesive powder includes at least one
of EVA, TPU, PE, PA, and PES. The hot melt adhesive powder can
ensure the formation of particles and the formation of particle
rods. Meanwhile, the hot melt adhesive powder has certain phase
change capability, so they can achieve a phase change cooling
effect to a certain extent. The mass ratio of the hot melt adhesive
powder in the cooling particles is 5%-50%, preferably 10%-40%, and
the content of other ingredients can be adjusted as required. The
proper amount of hot melt adhesive can ensure sufficient adhesion,
and excessive amount may block the channels during melting to
affect the cooling effect.
[0019] Optionally, the excipients include microcrystalline
cellulose and pre-gelatinized starch. Further, the cooling
particles have a diameter of 10-50 meshes, preferably 20-35
meshes.
[0020] Further, when used to cool the heat-not-burn cigarettes, the
cooling particles are granulated by extrusion rounding, are
spherical or approximately spherical particles, and have a bulk
density of 0.8 to 2.5 g/ml. The spherical or approximately
spherical shape can ensure complex enough and continuous smoke
channels inside the cooling filter rod, and the high enough
particle density can ensure that its adsorption performance is
minimized without affecting the amount of smoke produced by the
cigarette.
[0021] Further, when used for cooling conventional cigarettes, the
cooling particles are spherical or amorphous, and have a bulk
density of 0.4 to 1.6 g/ml. It can ensure complex enough and
continuous smoke channels inside the cooling filter rod, and the
low particle density can ensure that the internal pores of the
particles are not completely blocked, so that the particles still
have certain adsorption performance. Preferably, the moisture
content of the cooling particles is 5-15wt %, and further is 7-12wt
%. Keeping the moisture content in a proper moisture content range
can keep the cigarette in a good mouthfeel during smoking, and can
prevent mildew for the cooling filter rod containing plant fiber
powder.
[0022] The particles of proper diameters can ensure sufficient air
permeability inside the filter rod, and the proper moisture
facilitates storage and forming control.
[0023] Further, the effective porosity inside the cooling filter
rod is 65-95%. In this way, the entire cooling filter rod has a
porous structure with complex and continuous channels formed
inside; after the high-temperature smoke enters the cooling filter
rod from one end of the cooling filter rod, the high-temperature
smoke is quickly dispersed in the pores in the cooling filter rod
and fully contacts the cooling particles to exchange heat, thus
realizing cooling; in addition, the high-temperature smoke has a
long distance of travel in the cooling filter rod, so the cooling
effect achieved is good. The sufficient effective porosity can meet
the needs of air permeability inside the filter rod.
[0024] Further, the effective porosity inside the cooling filter
rod is 80-95%.
[0025] Further, the porous structure is honeycomb-like.
[0026] Optionally, the cooling filter rod is a loose and
air-permeable cylinder.
[0027] Further, the cooling filter rod is formed by the bonding of
the cooling particles through a binder.
[0028] Further, the cooling filter rod is mainly formed by the
cooling particles through the way of microwave heating or heat
solidification.
[0029] Further, the cooling filter rod is connected to a cut
tobacco section or a smoking section for smoking, wherein the
cooling filter rod is close to the cut tobacco/smoking section.
Optionally, a preparation method of the cooling filter rod includes
the following steps:
[0030] (1) mixing plant fiber powder and/or inorganic material
powder with relevant auxiliary molding materials, granulating,
drying, and screening to obtain particle bodies; then coating the
particle bodies with a phase change material to obtain cooling
particles; and
[0031] (2) molding the cooling particles obtained in step (1) to
obtain the cooling filter rod; or,
[0032] 1) thoroughly mixing at least one of plant
materials/inorganic materials/metal powder, hot melt adhesive
powder, microcrystalline cellulose, pre-gelatinized starch, water,
etc., granulating, drying, and screening to obtain particle bodies;
then coating the particle bodies with a phase change material to
obtain cooling particles of proper diameters; and
[0033] 2) molding the obtained cooling particles into a cylinder
with definite size, that is, the required cooling filter rod.
or,
[0034] 1) mixing plant fiber powder and/or inorganic material
powder with relevant auxiliary molding materials, granulating,
drying, and screening to obtain base particles;
[0035] 2) heating a phase change material for melting, weighing a
proper amount of flavor enhancer and adding it to the molten phase
change material, stirring and shearing at a high speed for thorough
and uniform mixing to obtain a mixed liquid for later use;
[0036] 3) coating the base particles prepared in step 1) with the
mixed liquid prepared in step 2) as a coating material to obtain
cooling particles; and
[0037] 4) molding the cooling particles prepared in step 3) into a
cylinder with definite size to obtain a flavor enhanced cooling
filter rod.
[0038] Based on the same inventive concept, the present invention
further provides an application of the aforementioned cooling
filter rod in the production of a cigarette.
[0039] Based on the same inventive concept, the present invention
further provides a cigarette, including the aforementioned cooling
filter rod.
[0040] Further, a cigarette includes a smoking portion and a filter
connected in sequence, wherein the aforementioned cooling filter
rod is arranged inside the filter.
[0041] Optionally, the cooling filter rod is compounded with
conventional filter rods in a certain ratio as a filter for
conventional cigarettes or heat-not-burn cigarettes, for example,
the cooling filter rod is arranged between two conventional filter
rods to constitute a cigarette filter portion (filter), and all
high-temperature smoke needs to pass through the cooling filter rod
before entering the mouth to ensure the cooling effect. Different
conventional filter rods are selected according to different usage
requirements.
[0042] Further, the conventional filter rods are acetate filter
rods, polypropylene fiber filter rods, paper filter rods, empty
tube rods, etc.
[0043] Compared with the prior art, the technical effects brought
by the technical solution of the present invention are:
[0044] (1) The phase change material is coated on the surface of
the particle material to form cooling particles, and the cooling
particles are integrally formed into a cooling filter rod, which
can be directly used for cigarette production after being
compounded with conventional filter rods.
[0045] (2) The cooling effect can be controlled according to the
amount of the phase change material and the cooling filter rod. The
form of the cooling filter rod is simple and novel, and the
bran-new filter rod facilitates industrial production and has low
cost and good cooling effect.
[0046] (3) The smoking resistance is small, and the contact area
between the smoke and the phase change material is large, so the
cooling efficiency is high, the temperature of smoke entering the
smoker's mouth can be greatly reduced, and the experience is
improved.
[0047] (4) The flavor enhancer is compounded with the phase change
material, so that the cooling filter rod realizes a flavoring
function for the first time, and its the application value greatly
increases.
[0048] (5) The temperature of smoke entering the mouth is greatly
reduced by controlling the effective porosity of the cooling filter
rod and using the means of no ventilation or dilution based on the
principle of physical cooling, and the cooling amplitude can reach
more than 50%.

particles containing menthone were taken; 5) the obtained cooling
particles were continuously molded with microwave into a loose and
porous cylinder with a circumference of 23.5 mm, and the cylinder
was cut into 120 mm long cooling filter rod sections; and 6) the
cooling filter rod sections were compounded with acetate fiber
sections in a length ratio of 10: 15 for preparing cigarettes,
wherein the cooling sections were close to cut tobacco, and acetate
fiber rods were also prepared into cigarettes of the same
specification as a control. The two kinds of filter rod cigarettes
were smoked, the temperatures at the outlet ends of the filter rods
were tested at the fifth time of smoking, and the temperature test
results were shown in Table 2. At the same time, the two kinds of
cigarettes smoked were evaluated, and the results were shown in
Table 3.
