Description

Technical Field

[0001] The present invention relates to the technical field of cigars, and in particular to a method for quickly shaping a cigar endometre and a pressure shaping device. Background Art

[0002] During the cigar production process, handmade cigars must be rolled after the inner blank is shaped before the wrapper can be applied. The shaping of the inner blank has a direct impact on the quality control of the subsequent wrapper application process, as well as the size, appearance and internal quality of the finished cigars.

[0003] During the shaping process of cigar stems, continuous external pressure is applied to the stem to maintain its shape. Currently, cigar stems are primarily shaped naturally using a shaping machine, requiring a long shaping process to meet cigar product quality requirements. For example, the journal document "The Effect of Shaping Time on the Appearance Quality of Hand-Rolled Whole-Leaf Cigars Under Certain Ambient Temperature and Humidity" states that "the optimal pressing time for hand-rolled whole-leaf cigars is 20-24 hours. A shorter time significantly impacts the appearance quality of the tobacco, resulting in a rough surface and poor appearance quality." "The optimum temperature for hand-rolled whole-leaf cigars is controlled at 20-25°C and a relative humidity of 60%-65%, which results in the highest pass rate for appearance indicators." This demonstrates that current shaping methods are time-consuming.

[0004] In the existing technology, there is little research on reducing the pressure shaping time of cigar tobacco endoplasm and improving the shaping efficiency. How to shorten the shaping time of cigar tobacco endoplasm and ensure the quality of the tobacco endoplasm is a problem that people in this field need to solve. Summary of the Invention

[0005] The present invention aims to solve the above problems and provides a method for quickly shaping the endoplasmic reticulum of a cigar and a pressure shaping device.

[0006] The technical solution to the problem solved by the present invention is to first provide a method for quickly shaping a cigar endoplasm, comprising the following steps:

[0007] S1. The rolled cigar is placed in a pressure shaping device and pressed into shape;

[0008] S2. Steaming the tobacco embryos in the pressure setting device at a temperature of 40-60°C for 5-10 minutes;

[0009] S3. The pressure shaping device is cooled to a temperature of 20 to 25°C.

[0010] S4. The cigarette endoplasm is kept in the pressure shaping device for 50 to 60 minutes to obtain the shaped cigarette endoplasm.

[0011] This application, for the first time, utilizes steam heating to assist in the pressure-setting of cigar tobacco embryos. Under pressure, the steam penetrates deeper into the tobacco, ensuring sufficient heating and softening of the tobacco leaves, effectively adjusting their shape in a short period of time. Then, still under pressure, the tobacco embryos are dried to a satisfactory moisture content within a short period of time, thus setting the shape. This setting method does not affect the quality of the cigars, effectively reduces odor and irritation, shortens the setting time, and improves rolling efficiency.

[0012] In step S2, the steam treatment temperature can be 40°C, 41°C, 42°C, 43°C, 44°C, 45°C, 46°C, 47°C, 48°C, 49°C, 50°C, 51°C, 52°C, 53°C, 54°C, 55°C, 56°C, 57°C, 58°C, 59°C, or 60°C, preferably 50°C. This relatively low-temperature steam can be obtained by controlling the pressure of a steam generator or by ultrasonically vibrating water at a certain temperature. The steam treatment duration can be 5 min, 6 min, 7 min, 8 min, 9 min, or 10 min, preferably 8 min.

[0013] As a preferred embodiment of the present invention, step S2 includes the following steps:

[0014] S21. Steam treatment at a pressure of 2.2-2.8 MPa for 30-60 seconds;

[0015] S22. After reducing the pressure by 0.01-0.1 MPa, flip the cigarette embryo and steam it for 1-5 seconds.

[0016] S23. Repeat steps S21 and S22.

[0017] During the steam treatment process, reducing the pressure to a certain extent firstly facilitates the flipping of the tobacco embryo and avoids damage to the shape of the tobacco embryo caused by excessive friction during the flipping operation. The flipping operation ensures that other parts of the tobacco embryo can also receive direct pressure and direct steam contact when the tobacco embryo subsequently undergoes step S21. By continuously flipping, all parts of the tobacco embryo can receive direct pressure and direct steam contact, ensuring that the pressure and steam are evenly distributed to each part of the tobacco embryo, thereby ensuring the overall shaping effect of the tobacco embryo. Secondly, after the pressure is reduced, the tobacco leaves that were originally compressed by the higher pressure can be slightly expanded and released, which helps the tobacco leaves maintain appropriate elasticity. At the same time, the distribution of the tobacco leaves in the tobacco embryo is adjusted to make it more even, avoiding local over-tightening or over-looseness, and ensuring the shaping effect and the appearance quality of the tobacco embryo. Third, steam treatment is performed on the cigarette inner embryo that is subjected to lower pressure. Compared with steam treatment on the cigarette inner embryo that is subjected to higher pressure, the diffusion speed of steam is relatively faster, and the steam quickly passes through the cigarette inner embryo, causing the cigarette inner embryo to be relatively more heated and less moistened, thereby achieving a thermal curing effect on the cigarette inner embryo and improving the shaping effect.

[0018] In step S21, the pressure can be 2.2 MPa, 2.3 MPa, 2.4 MPa, 2.5 MPa, 2.6 MPa, 2.7 MPa, 2.8 MPa, preferably 2.5 MPa; the steam treatment time can be 30 s, 35 s, 40 s, 45 s, 50 s, 55 s, 60 s, preferably 45 s.

[0019] In step S21, as a preferred embodiment of the present invention, steam treatment is performed at a pressure of 2.2-2.8 MPa for 27-52 seconds, followed by standing for 3-8 seconds.

[0020] Steam treatment can be continuous or intermittent, with intermittent treatment being preferred. A short period of resting can solidify the cigarettes, allowing them to fully adapt to their new shape and size, improving their stability and durability. In terms of cigarette inner embryo quality, steam can be given time to distribute evenly within the cigarette inner embryo, avoiding localized overheating and humidity, and stress caused by temperature and humidity differences that can lead to cracking. At the same time, chemical components in the cigarette inner embryo that are easily volatilized by the heat and humidity of steam are restored to a new equilibrium within the cigarette inner embryo, ensuring cigarette quality.

[0021] In step S22, the pressure can be reduced by 0.01 MPa, 0.02 MPa, 0.03 MPa, 0.04 MPa, 0.05 MPa, 0.06 MPa, 0.07 MPa, 0.08 MPa, 0.09 MPa, 0.1 MPa, preferably 0.05 MPa; the steam treatment time can be 1 s, 2 s, 3 s, 4 s, 5 s, preferably 3 s.

[0022] In step S3, the temperature of the cooled tobacco embryo can be 20°C, 21°C, 22°C, 23°C, 24°C, or 25°C, preferably 24°C.

[0023] As a preferred embodiment of the present invention, step S3 includes the following steps:

[0024] S31. Air-cooling treatment at 2.2-2.8 MPa for 20-30 seconds;

[0025] S32. After reducing the pressure by 0.01-0.1 MPa, flip the cigarette embryo and air-cool it for 1-5 seconds.

[0026] S33. Repeat steps S31 and S32 until the temperature of the tobacco embryo reaches 20-25°C.

[0027] First, similar to step S2, the entire tobacco embryo is uniformly cooled and shaped by flipping, and flipping is assisted by reducing pressure. Second, the tobacco embryo subjected to higher pressure is first air-cooled. The tobacco leaves in the tobacco embryo are tightly bound together, allowing the cold air to remain in the embryo for a longer time and allowing heat to transfer more easily between the tobacco leaves. This ensures uniform cooling of all parts of the tobacco embryo, reduces deformation or cracking caused by temperature gradients, and improves the strength of the tobacco embryo. Finally, the tobacco embryo subjected to lower pressure is air-cooled. The pores between the tobacco leaves help the cold air pass quickly through the tobacco embryo, removing excess moisture from the embryo and reducing the impact of moisture on the shaping effect.

[0028] In step S31, the air cooling treatment time can be 20s, 21s, 22s, 23s, 24s, 25s, 26s, 27s, 28s, 29s, 30s, and is preferably 25s.

[0029] In step S32, the air cooling treatment time can be 1s, 2s, 3s, 4s, or 5s, preferably 3s.

[0030] In step S4, the holding time can be 50 min, 51 min, 52 min, 53 min, 54 min, 55 min, 56 min, 57 min, 58 min, 59 min, or 60 min, and is preferably 55 min.

[0031] Secondly, another object of the present invention is to provide a pressure shaping device, comprising a base, a pressure plate, and a lifting structure for driving the pressure plate to move back and forth relative to the base; further comprising a shaping mold, the shaping mold comprising a lower mold arranged on the base, and an upper mold arranged on the pressure plate, a shaping cavity being formed in the shaping mold; further comprising a steam structure for introducing steam into the shaping cavity, and a cooling structure for introducing cold air into the shaping cavity.

[0032] As a preferred embodiment of the present invention, the base includes an inlet cavity connected to the steam structure and the cooling structure respectively, and the lower mold is provided with a lower through hole connected to the inlet cavity.

[0033] As a preferred embodiment of the present invention, the base is provided with a first mounting groove, the first mounting groove is provided with an inlet hole connected to the inlet cavity, the lower mold is rotatably arranged in the first mounting groove, and the lower through hole can be connected to the inlet hole; the pressure plate is provided with a second mounting groove, the upper mold is rotatably arranged in the second mounting groove, and the upper mold is provided with an upper through hole; the upper mold and the lower mold are detachably connected; and it also includes a rotating part for driving the shaping mold to rotate.

[0034] As a preferred embodiment of the present invention, an elastic cloth is provided in the second mounting groove, an air cavity is formed between the bottom of the second mounting groove and the elastic cloth, and the air cavity is connected to a gas part for inflating and deflating air; a mounting portion for accommodating the upper mold is formed between the elastic cloth and the notch of the second mounting groove.

[0035] As a preferred embodiment of the present invention, the upper mold is in a superior arc shape, and the lower mold is in a inferior arc shape.

[0036] As a preferred embodiment of the present invention, a pressure sensor and a temperature sensor are provided in the upper mold and / or the lower mold.

[0037] Beneficial effects of the present invention:

[0038] 1. The present application provides a method for rapidly shaping the endometrium of a cigar, which utilizes low-temperature steam and cooling to assist in pressure shaping of the endometrium of a cigar, so as to effectively adjust and solidify the shape of the endometrium in a short time. The shaping time only takes 1 to 2 hours, thereby shortening the shaping time and improving the shaping efficiency.

[0039] 2. In some embodiments, higher shaping pressure and lower shaping pressure are alternately used to assist steam or cold air in processing the tobacco embryo to further improve the shaping effect.

[0040] 3. The present application provides a pressure shaping device for carrying out the above method, which achieves the effect of quickly shaping the cigarette inner embryo by introducing steam or cold air while compressing it.

[0041] 4.

DETAILED DESCRIPTION

[0048] The following are specific embodiments of the present invention, which are combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0049] Example 1

[0050] A pressure shaping device, such as Figure 1 As shown, the system first comprises a base 1, a pressure plate 2, and a lifting structure that drives the pressure plate 2 to move back and forth relative to the base 1. Generally, to ensure the accuracy of the movement direction of the pressure plate 2, a fixed seat is provided on the base 1 via a support leg. The fixed seat has a guide hole, and a guide post is provided in the guide hole. The pressure plate 2 is located between the fixed seat and the base 1, and the pressure plate 2 is connected to the guide post. The guide hole of the fixed seat limits the guide post to ensure the movement direction of the pressure plate 2.

[0051] The choice of lifting structure is not limited. A hydraulic cylinder or a pneumatic cylinder can be used, and the end of the guide column located on the upper side of the fixed base can be directly connected to the piston rod of the hydraulic cylinder or the pneumatic cylinder. A screw lifting structure can also be used: in some embodiments, the guide hole can be set as a threaded hole, and the guide column can be set as a screw threadedly connected to the threaded hole, and the screw drives the pressure plate 2 to rotate downward or upward. In other embodiments, the guide hole is a through hole with a smooth inner wall, and the guide column is a screw; at the same time, a knob is provided on the fixed base through a rotating bearing, and the knob has an internal thread and is threadedly connected to the guide column; the support foot is provided with a slide groove in the vertical direction, and the pressure plate 2 is provided with a slider inserted into the slide groove and slides; this structure is basically the same as the ball screw structure. Turning the knob has a tendency to drive the guide column and the pressure plate 2 to rotate, but because the slider of the pressure plate 2 is confined in the slide groove, the rotation of the pressure plate 2 and the guide column is restricted. Therefore, under the action of the threaded connection, the guide column can move up and down, thereby driving the pressure plate 2 to move up and down.

[0052] Because the cigar stem blank needs to be shaped into a specific form, typically cylindrical, a cylindrical shaping mold 3 is also included. This mold 3 is divided into two parts: a lower mold 31 mounted on the base 1 and an upper mold 32 mounted on the pressing plate 2. The lifting mechanism drives the pressing plate 2 downward, allowing the upper mold 32 to contact the lower mold 31, forming a single integral shaping mold 3. A shaping cavity is then formed within the shaping mold 3. Furthermore, pressure sensors are installed within the upper mold 32 and / or the lower mold 31 to detect shaping pressure, as well as temperature sensors to monitor the temperature of the stem blank.

[0053] To accelerate shaping, the present application also includes a steam structure 4 for introducing steam into the shaping cavity, and a cooling structure 5 for introducing cold air into the shaping cavity. The steam structure 4 can be a conventional steam generator with controllable steam temperature, and the cooling structure 5 can be a conventional fan. To introduce the steam generated by the steam structure 4 or the cold air generated by the cooling structure 5 into the shaping cavity, a plurality of lower through holes 311 can be provided on the lower mold 31. The steam outlet of the steam structure 4 and the air cooling outlet of the cooling structure 5 can be connected to these lower through holes 311, respectively.

[0054] A method for quickly shaping cigar endoplasmic reticulum using the pressure shaping device comprises the following steps:

[0055] S1. Place the rolled cigar endometrium in the lower mold 31 of the pressure-setting device. Activate the lifting mechanism to move the pressing plate 2 and upper mold 32 downward, so that the upper mold 32 covers the endometrium and presses it tightly until the pressure sensor reaches 2.5 MPa.

[0056] S2. Open steam structure 4 and steam the cigarette embryos in the pressure shaping device at a temperature of 50°C for 7.5 minutes.

[0057] S3. Close the steam structure 4 and open the cooling structure 5 to cool the cigarette embryo in the pressure shaping device. After 5 minutes, the temperature of the cigarette embryo drops to 24°C and the cooling structure 5 is closed.

[0058] S4. Continue to maintain the pressure at 2.5 MPa for 55 minutes, then start the lifting mechanism to move the pressing plate 2 and the upper mold 32 upward to obtain the shaped cigarette embryo. At this time, the moisture content of the cigarette embryo is 12.5%.

[0059] Example 2

[0060] A pressure shaping device is basically the same as the pressure shaping device of Example 1, and the main differences are:

[0061] like Figure 3 and Figure 4 As shown, the shaping mold 3 is divided into two parts, a superior arc (i.e., an arc greater than half a circle) and an inferior arc (i.e., an arc less than half a circle). The upper mold 32 is a superior arc, and the lower mold 31 is an inferior arc. The upper mold 32 and the lower mold 31 are detachably connected, for example, a card slot is provided at the top of the lower mold 31, and a card block is provided at the bottom of the upper mold 32, and the card block can be inserted into the card slot; further, the card slot and the card block can be controlled to be connected through an electromagnet, for example, an electromagnet is provided in the card block, and an iron sheet is provided on the inner wall of the card slot. When the upper mold 32 and the lower mold 31 are connected together to form a complete shaping mold 3, the center of the shaping mold 3 is located on the upper mold 32, as shown in FIG. Figure 5 As shown, a connecting rod is provided at the center of the shaping mold 3 and is connected to a rotating member 33, such as a motor. Therefore, when the upper mold 32 and the lower mold 31 are connected together to form the complete shaping mold 3, the rotating member 33 can drive the shaping mold 3 to rotate, thereby causing the cigarette endoplasm therein to flip.

[0062] In order to make the shaping mold 3 able to rotate and still be fed with steam and cold air after rotation. Figure 3 and Figure 4 As shown, the base 1 is set to be hollow, and the hollow part forms an inlet cavity 1a, and the steam outlet of the steam structure 4 and the air cooling outlet of the cooling structure 5 are connected to the inlet cavity 1a respectively, so that steam or cold air can be introduced into the inlet cavity 1a.

[0063] Next, the top of the base 1 is recessed to form a first mounting groove 11. An inlet hole is provided in the top of the base 1, serving as part of the first mounting groove 11, to allow steam or cold air within the chamber 1a to escape. The lower mold 31 is then placed within the first mounting groove 11, ensuring that the lower through hole 311 of the lower mold 31 is connected to the inlet hole, allowing steam or cold air within the chamber 1a to enter the lower mold 31.

[0064] Similarly, the bottom of the pressing plate 2 is recessed upward to form a second mounting groove 21, and the upper mold 32 is disposed within the second mounting groove 21. Since the upper mold 32 is a superior arc, the corresponding second mounting groove 21 is also superior arc, making the notch width of the second mounting groove 21 smaller than the inner width of the groove, thereby preventing the upper mold 32 from falling out of the second mounting groove 21. At the same time, the upper mold 32 is provided with an upper through hole 321, which is the same shape and size as the lower through hole 311, so that the upper mold 32 can subsequently communicate with the inlet hole, thereby allowing steam or cold air in the inlet cavity 1a to enter the upper mold 32.

[0065] Meanwhile, a stretch fabric 22 is positioned within the second mounting groove 21. An air cavity 211 is formed between the bottom of the second mounting groove 21 and the stretch fabric 22. This cavity is connected to a gas element 23 for inflation and deflation. A mounting portion 212 for accommodating the upper mold 32 is formed between the stretch fabric 22 and the opening of the second mounting groove 21. When air is inflated into the air cavity 211, the stretch fabric 22 is pressed against the upper mold 32, increasing pressure on the upper mold 32 and, consequently, the pressure exerted by the upper mold 32 on the cigarette preform within it. The magnitude of this pressure is related to the amount of inflation gas. In some embodiments, a low-surface-energy coating, such as a polytetrafluoroethylene coating, is applied to the surface of the stretch fabric 22 proximal to the upper mold 32.

[0066] A method for quickly shaping cigar endoplasmic reticulum using the pressure shaping device comprises the following steps:

[0067] S1. Place the rolled cigar endometrium into the lower mold 31 of the pressure-setting device; appropriately inflate the air cavity 211 through the pneumatic component 23 until the elastic fabric is pressed against the upper mold 32; activate the lifting mechanism to move the pressing plate 2 and the upper mold 32 downward, so that the upper mold 32 covers the endometrium and presses it tightly. The upper mold 32 and the lower mold 31 are magnetically connected via an electromagnet. At this point, the pressure sensor displays a pressure of 2.45 MPa.

[0068] S21. Continue to inflate the air cavity 211 through the air piece 23 until the pressure sensor shows 2.5 MPa. Turn on the steam mechanism 4 to steam the cigarette embryos in the pressure shaping device at a temperature of 50° C. for 45 seconds.

[0069] S22. Keeping steam mechanism 4 open, partially evacuate the gas in air cavity 211 via gas element 23 until the pressure sensor displays 2.45 MPa. Then, rotating element 33 rotates the shaping mold 3 90°. The evacuation process takes approximately 1 second, the rotation process takes approximately 1 second, and the steaming process lasts for 2 seconds. Therefore, the steaming process is performed at 2.45 MPa for 3 seconds.

[0070] S23. Repeat steps S21 and S22 for 9 times, which takes about 7.5 minutes in total.

[0071] S3. Close the steam structure 4 and open the cooling structure 5 to cool the cigarette embryo in the pressure shaping device. After 5 minutes, the temperature of the cigarette embryo drops to 24°C and the cooling structure 5 is closed.

[0072] S4. Continue to maintain the pressure at 2.5 MPa for 55 minutes, then release the electromagnet connection between the upper mold 32 and the lower mold 31, start the lifting mechanism to drive the pressing plate 2 and the upper mold 32 to move upward, and obtain the finalized cigarette endoplasm.

[0073] Example 3

[0074] This embodiment is basically the same as embodiment 2, and the only difference is that:

[0075] S21. Continue to inflate the air cavity 211 through the air element 23 until the pressure sensor indicates 2.5 MPa. Open the steam mechanism 4 to steam the cigarette embryos in the pressure setting device at a temperature of 50°C for 40 seconds. Then close the steam mechanism 4 and wait for 5 seconds.

[0076] S22. Steam mechanism 4 is opened, and gas in cavity 211 is partially extracted via gas element 23 until the pressure sensor indicates 2.45 MPa. Rotating element 33 is then used to rotate mold 3 90°. The rotation process takes approximately 1 second, followed by 2 seconds of steaming. Therefore, steaming is performed at 2.45 MPa for 3 seconds.

[0077] S23. Repeat steps S21 and S22 9 times.

[0078] Example 4

[0079] This embodiment is basically the same as embodiment 2, except that S3 includes the following steps:

[0080] S31. Close steam structure 4 and open cooling structure 5 to cool the cigarette embryos in the pressure shaping device, and air-cool them at a pressure of 2.5 MPa for 25 seconds.

[0081] S32. Keeping the cooling structure 5 open, the gas in the air cavity 211 is partially extracted via the gas element 23 until the pressure sensor indicates 2.45 MPa. The shaping mold 3 is then rotated 90° via the rotating element 33. The rotation process takes approximately 1 second, followed by a cooling process of 2 seconds. Therefore, the cooling process is performed at 2.45 MPa for 3 seconds.

[0082] S33. Repeat steps S31 and S32 for 9 times until the temperature of the tobacco embryo reaches 24°C, which takes about 4.5 minutes. Then, close the cooling structure 5.

[0083] Example 5

[0084] The method for rapidly shaping cigar endoplasmic reticulum using the pressure shaping device of Example 2 comprises the following steps:

[0085] S1. Place the rolled cigar endometrium into the lower mold 31 of the pressure-setting device; appropriately inflate the air cavity 211 through the pneumatic component 23 until the elastic fabric is pressed against the upper mold 32; activate the lifting mechanism to move the pressing plate 2 and the upper mold 32 downward, so that the upper mold 32 covers the endometrium and presses it tightly. The upper mold 32 and the lower mold 31 are magnetically connected via an electromagnet. At this point, the pressure sensor displays a pressure of 2.45 MPa.

[0086] S21. Continue to inflate the air cavity 211 through the air element 23 until the pressure sensor indicates 2.5 MPa. Open the steam mechanism 4 to steam the cigarette embryos in the pressure setting device at a temperature of 50°C for 40 seconds. Then close the steam mechanism 4 and wait for 5 seconds.

[0087] S22. Steam mechanism 4 is opened, and gas in cavity 211 is partially extracted via gas element 23 until the pressure sensor indicates 2.45 MPa. Rotating element 33 is then used to rotate mold 3 90°. The rotation process takes approximately 1 second, followed by 2 seconds of steaming. Therefore, steaming is performed at 2.45 MPa for 3 seconds.

[0088] S23. Repeat steps S21 and S22 9 times.

[0089] S31. Close steam structure 4 and open cooling structure 5 to cool the cigarette embryos in the pressure shaping device, and air-cool them at a pressure of 2.5 MPa for 25 seconds.

[0090] S32. Keeping the cooling structure 5 open, the gas in the air cavity 211 is partially extracted via the gas element 23 until the pressure sensor indicates 2.45 MPa. The shaping mold 3 is then rotated 90° via the rotating element 33. The rotation process takes approximately 1 second, followed by a cooling process of 2 seconds. Therefore, the cooling process is performed at 2.45 MPa for 3 seconds.

[0091] S33. Repeat steps S31 and S32 for 9 times until the temperature of the tobacco embryo reaches 24°C, which takes about 4.5 minutes. Then, close the cooling structure 5.

[0092] S4. Maintain the pressure at 2.5 MPa for 55 minutes, then release the connection between the upper mold 32 and the lower mold 31, and start the lifting mechanism to move the pressing plate 2 and the upper mold 32 upward to obtain the shaped cigarette inner embryo.

[0093] Comparative Example 1

[0094] The shaping method using the pressure shaping device in Example 1 comprises the following steps:

[0095] The rolled cigar endoplasm is placed in the lower mold 31 of the pressure-setting device. The lifting mechanism is activated to move the pressing plate 2 and upper mold 32 downward, so that the upper mold 32 covers the endoplasm and presses it tightly until the pressure sensor reaches 2.5 MPa, which is maintained for 67.5 minutes. The lifting mechanism is then activated to move the pressing plate 2 and upper mold 32 upward, resulting in the finalized endoplasm.

[0096] Comparative Example 2

[0097] The shaping method using the pressure shaping device in Example 1 comprises the following steps:

[0098] The rolled cigar endoplasm is placed in the lower mold 31 of the pressure-setting device. The lifting mechanism is activated to move the pressing plate 2 and upper mold 32 downward, so that the upper mold 32 covers the endoplasm and presses it tightly until the pressure sensor reaches 2.5 MPa, which is maintained for 12 hours. The lifting mechanism is then activated to move the pressing plate 2 and upper mold 32 upward, resulting in the finalized endoplasm.

[0099] Cigars were made from 20 cigar endospores obtained in the Examples and Comparative Examples. Appearance quality testing was then performed in accordance with GB 15269 to determine whether the maximum deviation of the central axis, tightness, and other factors met the requirements. The pass rate was calculated, as shown in Table 1.

[0100] Table 1.

[0101]

[0102] As shown in Table 1, it can be seen that the present application can reduce the setting time while ensuring the setting effect on cigars.

[0103] The specific embodiments described herein are merely illustrative of the spirit of the present invention.
