Description

Technical Field

[0001] This invention relates to the field of cigar processing technology, and in particular to a method for grouping and processing cigar tobacco scraps. Background Technology

[0002] A cigar is a special tobacco product. Traditional cigars typically refer to hand-rolled cigars made entirely of tobacco leaves, meaning that all three components—filler, binder, and wrapper—are made from tobacco leaves, and the entire production process is done by hand. The raw materials for cigars are dried tobacco leaves with veins and stems, which undergo pre-treatment processes such as rehydration, industrial fermentation, stem removal, leaf sorting, and wrapper cutting. These processes ensure that the wrapper leaves reach the optimal state for hand-rolling in terms of leaf shape, size, integrity, and moisture content. Current pre-treatment processes for hand-rolled cigars, including the wrapper, binder, and filler, are all done manually. After rehydration and fermentation, the tobacco leaves are first manually removed from the stems, then sorted according to their appearance quality. The sorted wrapper leaves then enter the hand-rolling workshop, where workers cut the leaves by hand to the required wrapper size before rolling the cigars. This pretreatment process has many manual pretreatment steps, a long process flow, and low raw material utilization during the tobacco leaf cutting process. After the eggplant peel tobacco leaves are cut, a large amount of them are processed into scraps, making it difficult to achieve high-value utilization of tobacco resources.

[0003] In recent years, with the rapid development of domestic cigars, the amount of scraps generated during the cigar production process has also increased. How to effectively utilize these scraps has become an urgent problem to be solved.

[0004] Patent document CN108523198A discloses a pretreatment process for threshed and re-dried tobacco leaves based on the characteristics of the raw materials. The process includes vacuum rehydration, primary hot air moistening, and secondary hot air moistening. Prior to these processes, the tobacco leaves are first analyzed and classified based on their adhesion and moisture content. Pretreatment process parameters for different categories of tobacco leaves are determined based on the adhesion and moisture content test results. While this technical solution classifies tobacco leaves according to adhesion and moisture content before processing, it is not suitable for classifying and processing cigar tobacco scraps. This is because existing research shows that the adhesiveness of tobacco leaves varies with moisture content, ambient temperature, and external pressure. The current technical solution involves classifying raw tobacco leaves. For example, in its embodiments, the same type of raw tobacco leaves are usually stored in the same tobacco pack. The moisture content, ambient temperature, and external pressure of the same type of raw tobacco leaves within the same pack are basically the same, so the adhesiveness of these raw tobacco leaves is not significantly different. Therefore, when classifying raw tobacco leaves, only a portion of the samples within the pack needs to be tested to determine the grouping of all the raw tobacco leaves in the pack. However, for cigar tobacco scraps, these scraps come from cigars produced using different processes. Each type of cigar includes wrapper, binder, filler, and stuffing. Each of these components has different processing and storage requirements, resulting in significant differences in adhesiveness between different scraps. Furthermore, since these are only scraps, the quantity of each type of scrap is much less than that of raw tobacco leaves. If we expect to classify cigar tobacco scraps based on adhesiveness, the testing workload will be large and the work efficiency will be low. Summary of the Invention

[0005] The present invention aims to solve the above problems by providing a method for grouping and processing cigar tobacco scraps.

[0006] The technical solution to the problem of this invention is to provide a method for grouping and processing cigar tobacco scraps, comprising the following steps:

[0007] (1) Grouping:

[0008] S11. Based on whether or not they contain tobacco stems, the scraps are divided into: Group A (unprocessed) containing tobacco stems and Group B (processed) not containing tobacco stems.

[0009] S12. Based on moisture content, the scraps in group A (unfinished sheets) are divided into: high moisture content group A. 高 Group A with medium moisture content 中 Low moisture content group A 低 ;

[0010] S13. Based on the source, group A with medium moisture content 中 and low moisture content group A 低 The scraps inside are divided into: Group A, which is made from cigar wrappers and cigar filling tobacco. 中-薄 and low-thin group A低-薄 Medium-thickness group A, derived from cigar filler and cigar binder. 中-厚 and low thickness group A 低-厚 ;

[0011] (2) Pre-processing of unprocessed group A:

[0012] S21. For medium moisture content group A 中 The scraps inside are vacuum re-moistened until the moisture content reaches the high moisture content group A. 高 Moisture content;

[0013] S22. For low moisture content group A 低 The scraps inside are sequentially subjected to vacuum rehydration and hot air moistening treatments until the moisture content reaches the high moisture content group A. 高 Moisture content;

[0014] In the vacuum rehumidification of steps S21 and S22, each group of scrap materials is rehumidified for at least two cycles, including a water rehumidification cycle through water and a feeding rehumidification cycle through a mixture.

[0015] The thin group A 中-薄 and low-thin group A 低-薄 In this process, the feeding rehydration cycle is located after at least one water rehydration cycle, and the feeding rehydration cycle is carried out by rehydration with an aqueous solution of phosphatidylcholine with a concentration of 300~400mmol / L;

[0016] The medium-thickness group A 中-厚 and low thickness group A 低-厚 In this process, the feeding rehydration cycle is located before at least one water rehydration cycle, and the feeding rehydration cycle is carried out by rehydration with a sodium chloride aqueous solution with a concentration of 100~200 mmol / L;

[0017] S23. The medium moisture content group A that has been treated is now complete. 中 Low moisture content group A 低 Compared with high moisture content group A 高 The leaves were removed together;

[0018] (3) Pre-processing of pre-processed sheet group B: The scraps in pre-processed sheet group B are treated with hot air until the moisture content reaches that of high moisture content group A. 高 Moisture content;

[0019] (4) Final processing: The unprocessed tablet group A and the preprocessed tablet group B are mixed and then further processed.

[0020] This application pre-treats cigar tobacco scraps by grouping them according to whether they contain tobacco stems, moisture content, and origin, so that the moisture content and processing performance of the cigar tobacco scraps are uniform and can be processed together in subsequent processes, thereby improving the utilization value of cigar tobacco scraps.

[0021] In step S11, since scraps are generally used as fillers for sheet cigars and shredded cigars, and those containing tobacco stems need to have the stems removed manually or by leaf trimming, the scraps are first divided into unprocessed group A and processed group B based on whether they contain tobacco stems. Only unprocessed group A is trimmed, which avoids the problems of large fragmentation and low utilization rate that occur with scraps without tobacco stems during the trimming process, and ensures the shape and processing performance of processed group B.

[0022] The grouping of tobacco stems can rely on existing sorting equipment, including sorting equipment using image recognition technology and sorting equipment using gravity air separation technology. This can automatically separate scraps into unprocessed group A containing tobacco stems and processed group B without tobacco stems, which has the characteristics of low workload and high detection effect.

[0023] In step S12, since the moisture content of the scrap material affects its processing resistance for the unfinished sheet group A that requires leaf removal, if all unfinished sheet groups A are subjected to the same leaf removal intensity, some scrap material will be over-leaved while others will be under-leaved. Therefore, unfinished sheet groups A are also classified according to their moisture content. For group A with high moisture content... 高 Unfinished scraps are directly processed into leaves; for group A with medium moisture content 中 and low moisture content group A 低 Unprocessed scraps need to have their moisture content increased and stabilized within the range required for leaf cutting before leaf cutting can be carried out.

[0024] The grouping of moisture content can rely on existing moisture meters. The grouping criteria for high, medium, and low moisture content are not limited and depend on the moisture content range of the scraps. However, actual research has found that the moisture content of cigar tobacco scraps is typically between 12% and 35%. Therefore, as a preferred embodiment of the present invention, in step S12, the moisture content grouping criteria are: ≥25% moisture content is considered high moisture content, 18% ≤ moisture content <25% is considered medium moisture content, and <18% moisture content is considered low moisture content.

[0025] The moisture content of cigar tobacco scraps is related to its upstream processes. Generally, the moisture content of scraps produced during the unpacking, head drying, and filler drying processes is typically 12% to 13%, while scraps produced during fermentation have a moisture content of around 20%, and scraps from sheet cigar wrappers exceed 30%. Therefore, when cigar tobacco scraps are widely available and produced in large quantities, to reduce the workload associated with moisture content testing, the moisture content can be differentiated based on the source of the scraps. As a preferred embodiment of this invention, in step S12, scraps from sheet cigar wrappers have a high moisture content, scraps from the cigar tobacco fermentation process have a medium moisture content, and scraps from the unpacking, head drying, and filler drying processes have a low moisture content.

[0026] In step S13, the source of the cigar tobacco scraps can be marked directly during the collection stage.

[0027] In steps S21 and S22, due to the medium moisture content group A 中 Compared to group A with low moisture content, the unfinished scraps 低 Unfinished scraps have a similar moisture content range to those required for leaf trimming. Vacuum rehumidification can achieve a uniform moisture content while slightly increasing it to reach the desired range. Meanwhile, group A has a low moisture content. 低 The moisture content of the unfinished scraps is significantly different from the range required for leaf cutting. Vacuum rehydration alone is insufficient to raise the moisture content to the required range. Therefore, hot air moistening is added to further increase the moisture content.

[0028] In the process of increasing the moisture content of scrap materials, the inventors discovered that, due to the different sources of the scrap materials, even if the initial moisture content was the same, after vacuum rehumidification and / or hot air moistening under the same conditions, the moisture content of these scrap materials from different sources still differed significantly after storage equilibrium, thus still resulting in uneven leaf cutting. The inventors found that this is because scrap materials from different sources have different water absorption and retention capacities, which are also related to the thickness of the scrap materials. Therefore, based on the source of the scrap materials, they further categorized the medium moisture content group A... 中 and low moisture content group A 低 The unfinished scraps are divided into thin and thick groups. Different moisture content enhancement processes are used for the thin and thick groups to balance the final moisture content of the scraps.

[0029] The grouping criteria are as follows: The wrapper is typically thinner with finer veins and a smoother surface to ensure a flat and smooth appearance after rolling; the resulting scraps are considered thin materials. The filler and lower tobacco are also relatively thin, resulting in thin scraps. When selecting cigar tobacco for the filler and binder, based on the blend's efficacy, concentrated tobacco, flavorful tobacco, and upper tobacco are considered thicker materials, resulting in thicker scraps.

[0030] Among them, the medium-thin group A 中-薄 and low-thin group A 低-薄 The scraps inside absorb water quickly but retain it poorly. First, they are rehydrated with water to absorb a large amount of water; then, they are rehydrated again with phosphatidylcholine, which, through the barrier structure composed of lipid molecules, covers the cell membrane surface, thereby reducing cell membrane permeability and improving the water retention of the thin material. Meanwhile, the medium-thickness material A... 中-厚 and low thickness group A 低-厚 It absorbs water slowly but retains water well. First, use sodium chloride to rehydrate it, which increases the permeability of the plant cell membrane. Then, use water to rehydrate it, which allows it to absorb a large amount of water and increases its moisture content.

[0031] Specifically, in step S21, the thin group A 中-薄 Vacuum rehumidification is performed, with at least two rehumidification cycles, including a water rehumidification cycle and a feed rehumidification cycle. The feed rehumidification cycle uses a phosphatidylcholine aqueous solution with a concentration of 300-400 mmol / L, which can be 300 mmol / L, 310 mmol / L, 320 mmol / L, 330 mmol / L, 340 mmol / L, 350 mmol / L, 360 mmol / L, 370 mmol / L, 380 mmol / L, 390 mmol / L, or 400 mmol / L. The feed rehumidification cycle follows at least one water rehumidification cycle. For example, it can be two rehumidification cycles: first a water rehumidification cycle, then a feed rehumidification cycle. It can also be three rehumidification cycles: first two water rehumidification cycles, then a feed rehumidification cycle; or sequentially, a water rehumidification cycle, a feed rehumidification cycle, and a water rehumidification cycle.

[0032] Medium-thin group A 中-薄 In this preferred embodiment of the invention, a water rehydration cycle, a feed rehydration cycle, and a water rehydration cycle are performed sequentially to reduce the impact of phosphatidylcholine on the taste of scraps. More preferably, the vacuum degree of the water rehydration cycle is lower than that of the feed rehydration cycle to reduce the impact of water rehydration on the absorbed phosphatidylcholine.

[0033] Medium-thin group A 中-薄 In embodiments with at least two water rehydration cycles, preferably, the vacuum level decreases sequentially during each cycle. By gradually reducing the vacuum level, the rate of moisture evaporation and rehydration can be slowed down, allowing for a more uniform distribution of moisture within the scraps, thereby improving the quality and texture of the scraps. Preferably, the vacuum level decreases by 0.01 to 0.02 MPa each time.

[0034] Medium-thin group A 中-薄 In this invention, as a preferred embodiment, each rehydration cycle can be independently configured with: steam pressure ≥ 0.8 MPa, and water or phosphatidylcholine aqueous solution pressure ≥ 0.3 MPa.

[0035] Medium-thickness group A 中-厚 Vacuum rehumidification is performed, with at least two rehumidification cycles, including a water rehumidification cycle and a feed rehumidification cycle. The feed rehumidification cycle uses a sodium chloride aqueous solution with a concentration of 100-200 mmol / L, which can be 100 mmol / L, 110 mmol / L, 120 mmol / L, 130 mmol / L, 140 mmol / L, 150 mmol / L, 160 mmol / L, 170 mmol / L, 180 mmol / L, 190 mmol / L, or 200 mmol / L. The feed rehumidification cycle precedes at least one water rehumidification cycle. For example, there can be two rehumidification cycles: first the feed rehumidification cycle, then the water rehumidification cycle. Alternatively, there can be three rehumidification cycles: first the feed rehumidification cycle, then two water rehumidification cycles; or sequentially, a water rehumidification cycle, a feed rehumidification cycle, and a water rehumidification cycle.

[0036] Medium-thickness group A 中-厚 In a preferred embodiment of the present invention, after at least one water rehydration cycle, the scraps are further rehydrated using a phosphatidylcholine aqueous solution with a concentration of 300-400 mmol / L to improve the water retention rate of the scraps. Preferably, after this feeding rehydration cycle, at least one more water rehydration cycle can be performed to reduce the impact of phosphatidylcholine on the taste of the scraps. More preferably, the vacuum degree of the water rehydration cycle is lower than that of the feeding rehydration cycle to reduce the impact of water rehydration on the absorbed phosphatidylcholine.

[0037] Medium-thickness group A 中-厚 In embodiments with at least two water rehydration cycles, preferably, the vacuum level decreases sequentially during each cycle. By gradually reducing the vacuum level, the rate of moisture evaporation and rehydration can be slowed down, allowing for a more uniform distribution of moisture within the scraps, thereby improving the quality and texture of the scraps. Preferably, the vacuum level decreases by 0.01 to 0.02 MPa each time.

[0038] Medium-thickness group A 中-厚 In this invention, as a preferred embodiment, each rehydration cycle can be independently configured with: steam pressure ≥ 0.8 MPa, and water, sodium chloride aqueous solution, or phosphatidylcholine aqueous solution pressure ≥ 0.3 MPa.

[0039] In step S22, the low-thin group A 低-薄First, vacuum rehumidification is performed, with at least two rehumidification cycles, including a water rehumidification cycle and a feed rehumidification cycle. The feed rehumidification cycle uses a phosphatidylcholine aqueous solution with a concentration of 300-400 mmol / L, where the concentration can be 300 mmol / L, 310 mmol / L, 320 mmol / L, 330 mmol / L, 340 mmol / L, 350 mmol / L, 360 mmol / L, 370 mmol / L, 380 mmol / L, 390 mmol / L, or 400 mmol / L. The feed rehumidification cycle follows at least one water rehumidification cycle. For example, there can be two rehumidification cycles: first a water rehumidification cycle, then a feed rehumidification cycle. Alternatively, there can be three rehumidification cycles: first two water rehumidification cycles, then a feed rehumidification cycle; or sequentially, a water rehumidification cycle, a feed rehumidification cycle, and a water rehumidification cycle.

[0040] Low-thin group A 低-薄 In this preferred embodiment of the invention, a water rehydration cycle, a feed rehydration cycle, and a water rehydration cycle are performed sequentially to reduce the impact of phosphatidylcholine on the taste of scraps. More preferably, the vacuum degree of the water rehydration cycle is lower than that of the feed rehydration cycle to reduce the impact of water rehydration on the absorbed phosphatidylcholine.

[0041] Low-thin group A 低-薄 In embodiments with at least two water rehydration cycles, preferably, the vacuum level decreases sequentially during each cycle. By gradually reducing the vacuum level, the rate of moisture evaporation and rehydration can be slowed down, allowing for a more uniform distribution of moisture within the scraps, thereby improving the quality and texture of the scraps. Preferably, the vacuum level decreases by 0.01 to 0.02 MPa each time.

[0042] Low-thin group A 低-薄 In this invention, as a preferred embodiment, each rehydration cycle can be independently configured with: steam pressure ≥ 0.8 MPa, and water or phosphatidylcholine aqueous solution pressure ≥ 0.3 MPa.

[0043] Low-thin group A 低-薄 Next, hot air is used to moisten the leaves. As a preferred embodiment of the present invention, this is applied to the low-thin A group. 低-薄 A steam-water mixture is used to moisten the tobacco leaves. This process involves mixing water at a specific temperature with a certain proportion of steam, then atomizing the mixture to heat and humidify the tobacco leaves. It has a relatively low enthalpy but a relatively high moisture content, resulting in high humidification efficiency and alleviating the effects of low moisture content in tobacco leaves. 低-薄 The inner edge scraps suffer from water loss due to insufficient water retention. As a preferred embodiment of the invention, in the steam-water mixture for leaf humidification, the steam pressure is ≥0.8 MPa, the water pressure is ≥0.3 MPa, the hot air temperature is 110~140℃, and the exhaust hot air opening is 70±20%.

[0044] Low-thin group A 低-薄 In this preferred embodiment of the invention, after the leaves are moistened with hot air, they are sealed and stored for 18-24 hours to ensure uniform moisture content after moistening.

[0045] Low Thickness Group A 低-厚 First, vacuum rehumidification is performed, with at least two rehumidification cycles, including a water rehumidification cycle and a feed rehumidification cycle. The feed rehumidification cycle uses a sodium chloride aqueous solution with a concentration of 100-200 mmol / L, which can be 100 mmol / L, 110 mmol / L, 120 mmol / L, 130 mmol / L, 140 mmol / L, 150 mmol / L, 160 mmol / L, 170 mmol / L, 180 mmol / L, 190 mmol / L, or 200 mmol / L. The feed rehumidification cycle precedes at least one water rehumidification cycle. For example, there can be two rehumidification cycles: first the feed rehumidification cycle, then the water rehumidification cycle. Alternatively, there can be three rehumidification cycles: first the feed rehumidification cycle, then two water rehumidification cycles; or sequentially, a water rehumidification cycle, a feed rehumidification cycle, and a water rehumidification cycle.

[0046] Low Thickness Group A 低-厚 In a preferred embodiment of the present invention, after at least one water rehydration cycle, the scraps are further rehydrated using a phosphatidylcholine aqueous solution with a concentration of 300-400 mmol / L to improve the water retention rate of the scraps. Preferably, after this feeding rehydration cycle, at least one more water rehydration cycle can be performed to reduce the impact of phosphatidylcholine on the taste of the scraps. More preferably, the vacuum degree of the water rehydration cycle is lower than that of the feeding rehydration cycle to reduce the impact of water rehydration on the absorbed phosphatidylcholine.

[0047] Low Thickness Group A 低-厚 In embodiments with at least two water rehydration cycles, preferably, the vacuum level decreases sequentially during each cycle. By gradually reducing the vacuum level, the rate of moisture evaporation and rehydration can be slowed down, allowing for a more uniform distribution of moisture within the scraps, thereby improving the quality and texture of the scraps. Preferably, the vacuum level decreases by 0.01 to 0.02 MPa each time.

[0048] Low Thickness Group A 低-厚 In this invention, as a preferred embodiment, each rehydration cycle can be independently configured with: steam pressure ≥ 0.8 MPa, and water, sodium chloride aqueous solution, or phosphatidylcholine aqueous solution pressure ≥ 0.3 MPa.

[0049] Low Thickness Group A 低-厚 Next, hot air is used to moisten the blades. As a preferred embodiment of the present invention, this is applied to the low-thickness group A. 低-厚Steam humidification is performed on the tobacco leaves. Steam humidification mainly uses pure saturated steam to heat and humidify the tobacco leaves. It has a high enthalpy value and relatively low moisture content, which helps the steam penetrate into the interior of the tobacco leaves. Preferably, in the steam humidification process, the steam pressure is ≥0.8MPa, the hot air temperature is 90~120℃, and the exhaust hot air opening is 70±20%.

[0050] Low Thickness Group A 低-厚 In this preferred embodiment of the invention, after the leaves are moistened with hot air, they are sealed and stored for 18-24 hours to ensure uniform moisture content after moistening.

[0051] In step S23, the medium moisture content group A, the low moisture content group A (low), and the high moisture content group A (high) are all subjected to leaf trimming together. The leaf trimming parameters are not limited; however, as a preferred embodiment of this invention, a three-stage trimming and three-stage air separation process is used, with the leaf trimmer speed at 500-550 r / min and the air separation negative pressure at 0.3-0.8 kPa.

[0052] In step (3), the hot air humidification method for the prepared sheet group B is not limited, but steam humidification is preferred. In the steam humidification, the steam pressure is ≥0.8MPa, the hot air temperature is 90~120℃, and the exhaust hot air opening is 70±20%.

[0053] In step (4), the subsequent processing includes adding and moistening the leaves, storing the leaves, drying the leaves, mixing with other main blend tobacco leaves, and rolling.

[0054] The beneficial effects of this invention are:

[0055] 1. This application involves the refined pretreatment of cigar tobacco scraps after grouping them based on factors such as whether they contain tobacco stems, their moisture content, and their origin. Compared with single processing, this approach can fully leverage the sensory quality advantages of the raw materials, enhance the aroma and richness of the cigars, and by adjusting the processing parameters and intensity of each module in the grouping process, it allows the raw materials of each grade in the formula to exert their positive sensory effects as much as possible, thus providing a new processing method and approach for improving the quality of cigars.

[0056] 2. This application homogenizes the processing characteristics of different cigar tobacco scraps, which can improve the leaf yield, reduce breakage, and increase the utilization rate of raw materials. Attached Figure Description

[0057] Figure 1 This is a flowchart of a method for grouping and processing cigar tobacco scraps. Detailed Implementation

[0058] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0059] Example 1

[0060] A method for grouping and processing cigar tobacco scraps, such as Figure 1 This includes the following steps:

[0061] (1) Grouping:

[0062] S11. Based on whether or not they contain tobacco stems, the scraps are divided into: Group A (unprocessed) containing tobacco stems and Group B (processed) not containing tobacco stems.

[0063] S12. Based on moisture content, the scraps in the unfinished sheet group A are divided into: scraps with a moisture content ≥25% are classified as high moisture content group A. 高 Scrap materials with a moisture content of 18% to 25% are classified as medium moisture content group A. 中 Scrap materials with a moisture content of <18% are classified as low moisture content group A. 低 .

[0064] S13. Based on the source, group A with medium moisture content 中 The scraps inside are divided into: Group A, which is made from cigar wrappers and cigar filling tobacco leaves. 中-薄 Medium-thickness group A, derived from cigar filler and cigar binder. 中-厚 .

[0066] (2) Pre-processing of unprocessed group A:

[0067] Prepare a 150 mmol / L sodium chloride aqueous solution and a 350 mmol / L phosphatidylcholine aqueous solution under ultrasonic stirring for later use.

[0068] S21. For medium moisture content group A 中 The scraps inside are vacuum rehydration treated.

[0069] For the thin group A 中-薄 The scrap materials inside undergo one water rehydration cycle: vacuum degree 0.085MPa, steam pressure 0.8MPa, water pressure 0.3MPa, time 120s. Then, a feeding rehydration cycle is performed: vacuum degree 0.098MPa, steam pressure 0.8MPa, phosphatidylcholine aqueous solution pressure 0.3MPa, time 120s.

Then, a water rehydration cycle is performed: vacuum degree 0.085MPa, steam pressure 0.8MPa, water pressure 0.3MPa, time 120s.

[0071] S22. For low moisture content group A 低 The scraps inside are then subjected to vacuum rehydration and hot air moistening treatment in sequence.

Then, a feeding rehydration cycle is performed: vacuum degree 0.098MPa, steam pressure 0.8MPa, phosphatidylcholine aqueous solution pressure 0.3MPa, time 120s.

[0073] For low-thin group A 低-薄 After vacuum rehydration, the scraps are moistened with a mixture of steam and water: steam pressure 0.8 MPa, water pressure 0.3 MPa, hot air temperature 120℃, and exhaust hot air opening 70%. After hot air moistening, the leaves are sealed and stored for 22 hours.

[0074] For low-thickness group A 低-厚 The scrap materials inside undergo one feeding and rehydration cycle: vacuum degree 0.098MPa, steam pressure 0.8MPa, sodium chloride aqueous solution pressure 0.3MPa, time 120s. Then, a water rehydration cycle is performed: vacuum degree 0.085MPa, steam pressure 0.8MPa, water pressure 0.3MPa, time 120s.

[0075] For low-thickness group A 低-厚 After vacuum rehydration, the scrap materials are steam-moistened: steam pressure 0.8MPa, hot air temperature 95℃, and exhaust hot air opening 70%. After hot air moistening, the materials are sealed and stored for 22 hours.

[0076] S23. The medium moisture content group A that has been treated is now complete. 中 Low moisture content group A 低 Compared with high moisture content group A 高 Leaf removal is performed together: a three-stage leaf removal and three-stage air separation process is adopted, with the leaf removal machine speed at 525 r / min and the air separation negative pressure at 5 mbar.

[0077] (3) Pre-processing of pre-made sheet group B: The scraps in pre-made sheet group B are treated with hot air moistening, with a steam pressure of 0.8 MPa, a hot air temperature of 95℃, and a dehumidification hot air opening of 70%. After hot air moistening, the sheets are sealed and stored for 22 h.

[0078] (4) Final processing: After mixing the pre-processed unprocessed group A and the pre-processed group B, the leaves are sequentially added, moistened, stored, dried, mixed with other main blend tobacco leaves, and rolled.

[0079] Example 2

[0080] This embodiment is basically the same as Embodiment 1, except that:

[0081] S21. For medium moisture content group A 中 The scraps inside are vacuum re-moistened, and the medium-thin A group is processed. 中-薄 and the medium-thickness group A 中-厚 Three rehydration cycles were performed respectively.

[0082] For the thin group A 中-薄 The scrap materials are subjected to one water rehydration cycle: vacuum degree 0.085MPa, steam pressure 0.8MPa, water pressure 0.3MPa, time 120s. Then, a feeding rehydration cycle is performed: vacuum degree 0.098MPa, steam pressure 0.8MPa, phosphatidylcholine aqueous solution pressure 0.3MPa, time 120s. Finally, a water rehydration cycle is performed: vacuum degree 0.085MPa, steam pressure 0.8MPa, water pressure 0.3MPa, time 120s.

[0083] For medium-thickness group A 中-厚 The scrap materials are subjected to one water rehydration cycle: vacuum degree 0.085MPa, steam pressure 0.8MPa, water pressure 0.3MPa, time 120s. Then, a feeding rehydration cycle is performed: vacuum degree 0.098MPa, steam pressure 0.8MPa, sodium chloride aqueous solution pressure 0.3MPa, time 120s. Finally, a water rehydration cycle is performed: vacuum degree 0.085MPa, steam pressure 0.8MPa, water pressure 0.3MPa, time 120s.

[0084] Example 3
