Description
Technical field
The present invention relates to leaf tobacco production fields, in particular to a kind of coating fluid and heat cigarette core material of not burning.
Background technique
The production process for heating cigarette core material of not burning is the separation-regrouping process an of tobacco material, in production process
Middle tobacco material is divided into two parts of water phase soluble matter and insoluble object by extraction and separation technology, insoluble object by slurrying,
Equal process procedures of manufacturing paper with pulp form intermediate product --- the substrate of cigarette core material, and soluble matter is by techniques shapes such as purification, concentration, allotments
At another intermediate product --- coating fluid is backfilled to recombinate can be obtained on substrate and heats cigarette core material of not burning by coating fluid.
Conventional coating liquid preparing process is to mention raw material by water, separate, refining, being concentrated and form the water extracted immersing paste, then to leaching
Addition smoke agent, fragrance etc., which ultimately form, in cream heats the reconstituted tobacco coating fluid that do not burn.
Water proposes process and has the following problems in heating cigarette core material of not burning: in the coating fluid being configured to the water extracted immersing paste
Containing large quantity of moisture, water is converted into steam and can carry smoke agent, fragrance matter and is atomized loss together in drying process after coating.
In view of this, the present invention is specifically proposed.
Summary of the invention
The first object of the present invention is to provide a kind of coating fluid, it is possible to prevente effectively from sending out in the drying process after coating
Fumicants and fragrance matter atomization are lost.
The second object of the present invention is to provide a kind of heating and does not burn cigarette core material, and fragrance matter content is higher.
In order to realize above-mentioned purpose of the invention, the following technical scheme is adopted:
A kind of coating fluid, preparation method include:
Smoke agent, cosolvent are mixed to get Extraction solvent, progress multistage is then mixed with tobacco material and is mentioned
Take liquid；
The extracting solution is concentrated to get medicinal extract, auxiliary agent is then added, obtains the coating fluid.
Extraction solvent is obtained using smoke agent as one of ingredient of Extraction solvent and cosolvent cooperation, adjustment is extracted molten
The polarity of agent, smoke agent will be dissolved in so that extraction process is more selective by changing extraction process by water pure in the prior art
Ingredient more effectively extract, and the ingredient insoluble in smoke agent (i.e. smoke agent is difficult to carry smoke) does not extract then or few
It extracts, finally formed coating fluid good fluidity is easy to permeate, and product, which is not easy stickness agglomeration, is beneficial to subsequent processing.
The heating that coating fluid provided by the present application is suitable for wet process preparation is not burnt cigarette core material.

Or using ultrasonic wave as assisted extraction means, each contribute to improve extraction efficiency.
Preferably, the mass content of Extraction solvent described in the medicinal extract is less than or equal to 3%.
The mass content for limiting the Extraction solvent in medicinal extract is to guarantee a large amount of volatility object during following process
Matter, which is volatilized, to be taken away, and the quality of tobacco leaf is reduced.
Preferably, the auxiliary agent includes one of essence, fragrance and bacteriostatic agent or a variety of.
The addition of auxiliary agent is the integrated quality in order to improve final products, tart up, prevent it is mouldy, extend the shelf life.
Optionally, the tobacco material is obtained by raw material by cleaning, being uniformly mixed.
The purpose of purification is to improve overall quality for dust, the foreign matter in raw material of going out.
It is a kind of to heat cigarette core material of not burning, it is coated on tobacco leaf substrate and is made using the coating fluid.
Compared with prior art, the invention has the benefit that

It takes.
Comparative example 1
Difference from Example 1 is, is extracted using water as Extraction solvent and prepares coating fluid, is then prepared into
Heat cigarette core material of not burning.
Embodiment 1-5 and comparative example 1 are sampled, all samples balance 48 under the conditions of 22 DEG C, humidity 45% ± 2%
Hour, then weighing heats 2h in Muffle furnace, weighs after cooling, calculate total volatility of each sample at 350 DEG C.Its result
It is as shown in table 1 below:
The total volatility test result of 1 sample of table
As upper table 1 it is found that heating cigarette core material of not burning made from coating fluid provided by the present application, total volatility is higher than
Existing extraction process by water.It shows that the heating that the application obtains is not burnt reconstituted tobacco, and the volatile materials contained is more, more
It is easy to produce fragrance.
Chloride ion, potassium ion, nitrate ion can't participate in the flue gas for heating cigarette core material generation of not burning, also
Raw sugar is a part in total reducing sugar, and cracking can occur during heating and release a certain amount of cigarette for total reducing sugar, reduced sugar, total nitrogen
Gas, but it contributes seldom the amount of smoke for heating cigarette core material of not burning, about 5%~10%, excessively also result in miscellaneous gas
Generate, therefore also to reduce the extracted amount of chloride ion, potassium ion, nitrate ion in extraction process, control total reducing sugar, reduced sugar and
The extracted amount of total nitrogen.
Each composition quality content in the medicinal extract that testing example 1 and comparative example 1 obtain, compared with comparative example 1, embodiment
In 1 obtained medicinal extract, total sugar content decline 28.59%, nicotine content decline 29.79%, content of reducing sugar decline 30.07%,
Total nitrogen content decline 73.79%, potassium content are reduced to 0, nitrate content decline 76.92%, chloride ion content decline 58.89%.
It follows that using coating fluid made from method provided by the present application, chloride ion, nitrate ion, total reducing sugar, is gone back potassium ion
Coating fluid of the content of raw sugar and total nitrogen than obtaining using water as Extraction solvent decreased significantly, and advantageously reduce harmful substance
With the extraction for the substance for being not involved in smog generation, the generation of miscellaneous gas is avoided.
Coating fluid provided by the present application, is added smoke agent in Extraction solvent, and the dissolution of extraction process solute has better
Selective, fragrance matter ratio improves in coating fluid, harmful substance contents reduce, reduces the generation of miscellaneous gas when smog generation, dry
Fragrance matter is lost few during dry；Coating fluid good fluidity is easy to permeate, and product, which is not easy stickness agglomeration, is beneficial to subsequent processing；
The fragrance matter content for heating cigarette core material of not burning is higher, and quality is more preferable.
Although illustrate and describing the present invention with specific embodiment, it will be appreciated that without departing substantially from of the invention
