Description

Elution treatment device for cut stems for cigarettes and operation method thereof
Technical Field
The invention belongs to the field of novel tobacco smoking tools, and relates to an elution treatment device for cut stems for cigarettes and an operation method thereof.
Background
In recent years, as the quality of cigarettes is improved by consumers, designers begin to optimize the cigarette details, and the whiteness of the cigarette ash is one of the cigarette ash. Generally speaking, the whiteness of cigarette ash can be roughly divided into two kinds, one is ash column whiteness, namely the whiteness of the outer surface of columnar ash presented after the cigarette is burnt; the other is the whiteness of the tobacco shred ash, namely the whiteness of the tobacco shred combustion ash presented after the internal tobacco shreds are peeled off from the cigarette paper ash after being combusted. The whiteness of ash column of the cigarette is mainly related to the combustion property of cigarette paper and the matching property of the cigarette paper and tobacco shreds; the whiteness of the tobacco ash is mainly determined by the formula structure and additives of the tobacco.
Although the incorporation of functional additives into tobacco shreds improves the whiteness of the tobacco ash, they are rarely used because they tend to present unpredictable safety hazards.
In addition, the stem shreds are compact in structure and easy to burst during combustion, the ash property of cigarette packages is affected, and the stem shreds cannot be directly used in tobacco shred formulas generally. Although the burst condition of the expanded cut stems can be greatly reduced, the content of nonflammable components such as pectin and the like contained in the expanded cut stems is still high, so that the burning ash of the expanded cut stems is generally blacker, the ash of cigarettes is blackened, and the consumption experience of consumers is influenced.
The present invention has been made to solve the above problems.

Preferably, the cut rolled stem stripper chamber 17 further has a fixing buckle 12 inside, which is located above the perforated transfer filter disk 11, and the perforated transfer filter disk 11 is fixed inside the cut rolled stem stripper chamber 17 by the fixing buckle 12 when sliding upwards to the position of the fixing buckle 12.
Preferably, the horizontal heights of the first discharge port 18, the pneumatic drying conveyor 24 and the second feed port 32 are in a relation that the first discharge port 18 is larger than or equal to the pneumatic drying conveyor 24 and larger than or equal to the second feed port 32. So that the cut stems can smoothly enter the next procedure after finishing the procedures.
More preferably, the level of the first discharge port 18 is higher than that of the pneumatic drying conveyor belt 24, and the cut stems output from the first discharge port 18 fall onto the pneumatic drying conveyor belt 24 by natural gravity; the level of the pneumatic drying conveyor belt 24 is higher than that of the second feed inlet 32, and cut stems on the pneumatic drying conveyor belt 24 fall into the pressure-reducing balancing chamber 36 through the second feed inlet 32 by natural gravity;
preferably, the pneumatic drying conveyor 24 is made of a metal conveyor capable of ventilating.
In a second aspect of the present invention, an operation method of the elution processing device for tobacco cut stems according to the first aspect of the present invention is provided, wherein cut stems and an elution solution are injected into the elution assembly 1, after one or more times of elution, pneumatic drying is performed on the pneumatic drying conveyor 24, and the pneumatic drying conveyor is conveyed into the reduced pressure balancing assembly 3, and a repairing agent is added to perform reduced pressure repairing, so as to obtain a required cut stem product.
The method specifically comprises the following steps:
a. closing the water outlet 14, putting the cut stems on the perforated conveying filter disc 11 in the cut stem elution chamber 17, adding eluent 16 through the first feed inlet 13 until the liquid level of the eluent 16 can completely immerse the cut stems, then starting the first heater 15, heating the eluent (16) to elute the cut stems, lifting the perforated conveying filter disc 11 to reach the level of the first discharge outlet 18, stabilizing for 0.5-1min, enabling the eluent 16 in the cut stems to fall back to the bottom of the cut stem elution chamber 17, opening the water outlet 14, and discharging the eluent 16;
b. after the cut stems finish the elution process, starting the conveying function of the conveying filter disc with the holes 11, and conveying the eluted cut stems to the airflow drying conveyor belt 24 through the first discharge hole 18 for conveying; simultaneously turning on the second heater 21 and the blower 22 to perform air flow drying on the cut stems on the air flow drying conveyor belt 24;
c. after the cut stems are conveyed by the airflow drying conveyor belt 24 and fall into the pressure reduction balancing chamber 36 through the second feed port 32, a certain amount of repairing agent is added through the second feed port 32, the second feed port 32 and the ventilation opening 33 are closed, the pressure reduction is started through the instrument panel 35 for controlling the pressure after the pressure reduction balancing chamber 3610-30s is rotated along the central rotating shaft 31, and meanwhile, the whole pressure reduction balancing chamber 36 is continuously rotated to perform the pressure reduction diffusion process;
d. after the balance is finished, the ventilation opening (33) is opened, so that the outside air enters the decompression balance chamber (36), when the inside and outside air pressure is equal, the second feeding hole (32) is opened, and the well-treated tobacco stem shreds are taken out.
Wherein, step a can be repeated for a plurality of times.
In a preferred embodiment of the second aspect of the present invention, in step a, the eluent (16) is water or an organic solvent, which refers to a washing solvent commonly used in the art, such as ethanol; in step c, the repairing agent is glycerol or propylene glycol repairing agent.
In a preferred embodiment of the second aspect of the invention, in step a, the elution temperature is in the range of 40-60 ℃; the elution time is 20-40 min. The stem structure is seriously damaged due to overhigh temperature of the eluent or overlong dipping time, and the breakage rate in the subsequent process is greatly increased; too low an eluant temperature or too short an immersion time can lead to insufficient elution and limited improvement in whiteness.
In a preferred embodiment of the second aspect of the present invention, in step b, the conveying speed of the pneumatic drying conveyor belt (24), the temperature of the second heater (21) and the blowing rate of the blower (22) are adjustable to ensure that the moisture content of the cut stems is controlled within 20% when the cut stems fall into the reduced-pressure balancing chamber (36). More preferably, the moisture content of the cut stems after the pneumatic drying is controlled within the range of 8-10%. The typical drying gas stream temperature is 100-120 ℃.
In a preferred embodiment of the second aspect of the invention, in step c, the pressure is generally controlled between 400mbar and 800mbar, the equilibration time is between 20 and 40min, and the repairing agent is added in an amount of 5% to 15% of the mass of the cut stems.
Wherein, if the repairing dosage is too small, the effect of full repair cannot be achieved; too large can make the cut stems too wet, which is not conducive to subsequent production.
Reducing pressure to balance the diffusion pressure, wherein when the pressure is too high, glycerol or propylene glycol molecules are not easy to fully diffuse; when the size is too small, atomization is easy to generate, and glycerol or propylene glycol molecules are not beneficial to the penetration of the inside of the cut stems.
The diffusion time is balanced by reducing the pressure, and if the time is too short, the diffusion is insufficient and the complete balance cannot be realized; if the length is too long, the balanced diffusion is basically finished, the effect is not large, and the waste of time and energy consumption is caused.
The method has the advantages that pressure reduction balance diffusion is adopted in the repairing process, compared with tobacco shreds, the tobacco shreds are hard, compact in structure and not beneficial to elution and repair, if the repairing agent is sprayed on the surfaces of the tobacco shreds and then naturally diffuses, the repairing agent can only stay on the surfaces of the tobacco shreds and cannot reach the insides of the tobacco shreds, the flexibility of the tobacco shreds is not obviously improved, so that breakage cannot be effectively reduced, compared with natural diffusion, the method is more beneficial to reducing the breakage rate and improving the whiteness of the ash of the cigarettes by adopting the pressure reduction balance diffusion.
In conclusion, the invention designs the pressure reducing balance component aiming at the repairing process pertinence and provides specific pressure reducing balance diffusion and pressure reducing balance diffusion time.
The invention has the following beneficial effects:
1. compared with the common cut stems, the cigarette manufactured by the cut stems processed by the device has the advantages that the ash whiteness can be generally improved by 15-30 units and the ash condensation index can be generally reduced by 1-2 units according to the standard method.
2. The invention adopts the pressure reduction balance component, can quickly diffuse and permeate the repairing agent on the surface of the cut stem in a short time, and the produced product is more uniform and has good stability.
3. The invention provides an elution treatment device for cut stems for cigarettes, which can perform elution, repair and other operations on the cut stems and solve the problem of blackening of cigarette ash caused by the cut stems. Specifically, the device integrates the elution, the drying and the restoration, is convenient for an operator to solve multiple steps in the processing process of the cut stems at one time, is simple and easy to implement, has strong universality and is convenient to popularize.
4. The method carries out repairing treatment on the cut stems after dipping and elution so as to repair the milk processing strength of the cut stems and greatly reduce the crushing rate, and the crushing rate of the process for treating and improving the whiteness of the ash of the cigarettes by adopting the method can be controlled within 10-20 percent, thereby saving the production cost. The invention provides a specific elution and repair method aiming at cut stems, and compared with cut tobacco, the cut stems are hard per se, compact in structure and not beneficial to elution and repair, and especially in the repair process, after a repair agent is sprayed on the cut stems, the pressure reduction balance diffusion is carried out for a certain time, wherein the pressure of the pressure reduction balance diffusion is controlled to be 400-800 mbar, and when the pressure is too high, molecules of the repair agent are not easy to fully diffuse; and when the size is too small, atomization is easy to generate, and the infiltration of molecules of the repairing agent into the cut stems is not facilitated. The diffusion time is 20-40 min. If the time is too short, the diffusion is insufficient, and the repairing agent cannot permeate into the cut stems; if the length is too long, the balanced diffusion is basically finished, the effect is not large, and the waste of time and energy consumption is caused. Under the condition, the processing resistance strength of the cut stems can be obviously improved, the influence on chemical components inside the cut stems can be avoided, and the fine adjustment on the difference of the chemical components is also needed after the processing resistance of the cut stems is restored. Compared with the method of independently spraying and naturally diffusing, the method of the invention has the advantages that the stalk filament is repaired, the breaking rate of the process for improving the whiteness of the cigarette ash is lower, and the whiteness of the cigarette ash is improved more obviously. The grinding rate of the process for improving the whiteness of the cigarette ash is about 20-30 percent by natural diffusion after being independently sprayed. If only spray into natural diffusion behind the repairing agent on the stalk silk surface, the repairing agent can only stay on the stalk silk surface, can't reach inside the stalk silk, and is not obvious to the promotion of stalk silk pliability to lead to can not effectual reduction to make garrulous. Compared with natural diffusion, the adoption of pressure reduction and balanced diffusion is more beneficial to reducing the breakage rate and improving the whiteness of the ash of the cigarettes.
5. The moisture content of the cut stems before decompression and diffusion is within 20%, and preferably the moisture content of the cut stems after airflow drying is controlled within the range of 20-30%, so that the moisture content is too high, the cut stems after decompression and diffusion are too wet, the cut stems can be used after further moisture removal, and the moisture content is too low, a large amount of broken stems are generated in the previous drying process.

Detailed Description
The present invention will be described in further detail with reference to specific embodiments, but it should not be construed that the scope of the present invention is limited to the following examples. Various alterations and modifications made by those skilled in the art and ordinary skill in the art without departing from the spirit of the method described above are intended to be included within the scope of the invention.
The whole device for preparing the cut rolled stems is shown in figure 1.
In addition, in the present example, the whiteness of the coiled ash was measured by a conventional powder whiteness measurement method, and the ash fusion index was calculated by the method described above.
Example 1
As shown in fig. 1, the method for processing the expanded cut stems specifically comprises the following steps:
a. closing the water outlet 14, putting the cut stems on the perforated conveying filter disc 11 in the cut stem elution chamber 17, adding water through the first feed inlet 13 until the liquid level of the eluent 16 can completely immerse the cut stems, then starting the first heater 15, heating the eluent (16) to elute the cut stems, lifting the perforated conveying filter disc 11 to reach the height of the fixed buckle 12, stabilizing for 0.5-1min, enabling the eluent 16 in the cut stems to fall back to the bottom of the cut stem elution chamber 17, opening the water outlet 14, and discharging the eluent 16;
the above elution process is repeated after the water outlet 14 is closed again and the height of the perforated transfer filter tray 11 is lowered, as required by the actual production.
The elution temperature was 40 ℃; the elution time was 30 min.
b. After the cut stems finish the elution process, starting the conveying function of the conveying filter disc with the holes 11, and conveying the eluted cut stems to the airflow drying conveyor belt 24 through the first discharge hole 18 for conveying; simultaneously turning on the second heater 21 and the blower 22 to perform air flow drying on the cut stems on the air flow drying conveyor belt 24;
the conveying speed of the pneumatic drying conveyor belt 24, the temperature of the second heater 21 and the blowing rate of the blower 22 are adjustable, so that when the cut stems fall into the reduced-pressure balancing chamber 36, the moisture content of the cut stems is controlled to be about 8%.
c. When sufficient cut stems are conveyed by the airflow drying conveyor belt 24 and fall into the pressure reduction balancing chamber 36 through the second feed opening 32, a certain amount of glycerol repairing agent is added through the second feed opening 32, the second feed opening 32 and the vent opening 33 are closed, and after the pressure reduction balancing chamber 3620s is rotated along the central rotating shaft 31, pressure reduction is started through the instrument panel 35 for controlling pressure, and meanwhile, the whole pressure reduction balancing chamber 36 is continuously rotated to perform a pressure reduction and diffusion process;
the pressure is controlled at 400mbar, the balance time is 40min, and the addition amount of glycerol is 5% of the mass of the stem.
d. After the balance is finished, the vent 33 is opened to enable the external air to slowly enter the decompression balance chamber 36, when the internal air pressure and the external air pressure are equal, the feed port 32 is opened, and the processed cut stems are taken out to be the cut stem products.
Wherein step a is repeated twice.
The shredding rate of the cut stems obtained by the method is about 12.3 percent. The cut stems are prepared into cigarettes (No. 2) by mixing the cut stems with cut tobacco without stems according to the proportion in the original formula, and the results are compared with the results of the original cigarettes (No. 1):
sample numbering Whiteness of ash Index of ash coagulation
1# 96.2 6.1
2# 121.2 4.9
As can be seen from the table above, compared with the original cigarette sample, the whiteness and the ash condensation index of the cigarette ash produced by adopting the processed cut stems are obviously improved.
Comparative example 1
Comparative example implementation differs from example 1 only in that the reduced-pressure equilibrium diffusion in example 1 for 60min was replaced by natural diffusion for 60min and then removed.
The shredding rate of the cut stems obtained by the method is about 27.4 percent. The cut stems are prepared into cigarettes (No. 2) with cut stems without cut stems according to the proportion in the original formula and compared with the original cigarettes (No. 1), and the results are as follows:
sample numbering Whiteness of ash Index of ash coagulation
1# 96.2 6.1
2# 104.2 5.6
As can be seen from the above table, the whiteness and the ash condensation index of the cigarette ash produced by using the processed cut stems are slightly improved compared with the original cigarette sample.
Compared with the comparative example 1, the cut stems treated by the method have more remarkable influence on the whiteness and the ash condensation index of the cigarette ash, probably because the reduced pressure diffusion process can enable the glycerol to penetrate into the cut stems more remarkably, so that the same amount of glycerol is distributed in the cut stems more uniformly, and the conditions that the combustion is insufficient due to overhigh concentration of the glycerol at partial positions, the ash is blackened and the ash condensation index is not good are reduced. In addition, compared with natural diffusion, the reduced-pressure balanced diffusion is more beneficial to reducing the fragmentation rate.
