[0038] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present application.
[0039] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.
[0040] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.
[0041] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0042] This application provides a method for sealing cigarettes to prevent mold growth. Paper made from bamboo fiber pulp, corn cob pulp, and cigarette paper pulp is used to seal the tobacco end of the cigarette. Bamboo fiber has excellent anti-mold properties, while corn cob pulp has good biodegradability, water and moisture resistance, tear resistance, and water absorption. Sealing the tobacco end with this paper can prevent humid air and mold spores from entering the inside of the cigarette and causing mold growth.
[0043] like Figure 1 As shown, the anti-mildew cigarette sealing method provided in this application includes:
[0044] S110: Produces bamboo fiber pulp and corn cob pulp.
[0045] Bamboo fiber has excellent anti-mildew properties, mainly due to the natural antibacterial components "bamboo quinone" and "sodium copper chlorophyllin" contained within it. These components give bamboo fiber powerful antibacterial, bacteriostatic, and antimicrobial abilities. Furthermore, the ultra-fine porous structure of bamboo fiber allows it to absorb moisture, giving it breathable, moisture-regulating, and moisture-proof characteristics.
[0046] As one example, the preparation of bamboo fiber pulp specifically includes:
[0047] Q1: Obtain bamboo pulp from bamboo raw materials.
[0048] As one example, obtaining bamboo pulp from bamboo raw materials specifically includes:
[0049] P1: Select bamboo that is growing well and free of mold, cut off the root and tail, and split the bamboo diameter to make bamboo strips of the second preset size.
[0050] As an example, the second preset size is 1m in length and 0.03m in width.
[0051] P2: Place the bamboo strips into the drying oven and dry them at the second preset temperature for the second preset time. After removing them, let them cool for the third preset time.
[0052] As one example, the second preset temperature is 60°C, the second preset time is 4 hours, and the third preset time is 2 hours.
[0053] P3: Soak the cooled bamboo strips in clean water to soften them, remove the green and yellow parts of the bamboo, and obtain the bamboo flesh.
[0054] Q2: Place the bamboo meat in a steaming basket containing steaming liquid and steam it at the first preset temperature for the first preset time.
[0055] As an example, the first preset temperature is 100°C and the first preset time is 2 hours.
[0056] Through processes such as steaming and high-temperature baking, bamboo fibers lose their nutrients, making it impossible for insects and fungi to attach to them. Therefore, products made from bamboo fibers, such as wall panels and mattresses, are less prone to insect infestation under normal use.
[0057] Q3: The steamed bamboo pulp is repeatedly crushed and cut, and then made into bamboo fiber pulp using pulping equipment.
[0058] Corn cob refers to the core part of a corn cob. It is made by threshing and processing corn kernels and then strictly screening them. As an agricultural waste, corn cob has excellent biodegradability and a certain mechanical strength. It also has the characteristics of uniform texture, suitable hardness, low pollution, good waterproof and moisture-proof properties, good tear resistance, good toughness, and good wear resistance. At the same time, it has a water absorption capacity of more than 3 times its own weight, making it very suitable as a sealing material.
[0059] As one example, the preparation of corn cob pulp specifically includes:
[0060] R1: Remove the rough outer skin, impurities, dust, etc. from the corn cob to obtain a clean corn cob containing cellulose and hemicellulose.
[0061] R2: Use a grinder to grind clean corn cobs into corn cob particles of a preset size.
[0062] Preferably, the size of the corn cob particles is 58-62 mesh.
[0063] R3: Soak the corn cob kernels in clean water to allow them to fully absorb water.
[0064] R4: Place the soaked corn cob particles into a steaming device for high-temperature and high-pressure steaming.
[0065] R5: Put the steamed corn cob particles into a pulping machine to make corn cob pulp.
[0066] S120: Add bamboo fiber pulp and corn cob pulp to cigarette paper pulp to make mixed pulp.
[0067] As one example, bamboo fiber pulp and corn cob pulp are added to cigarette paper pulp to prepare a mixed pulp, specifically including:
[0068] S1201: Add bamboo fiber pulp and corn cob pulp to cigarette paper pulp, and use a pulper equipped with a jaw crusher for combined pulping and filtration.
[0069] Preferably, when adding cigarette pulp, the mass ratio of corn cob pulp to the mixed pulp is less than 10%.
[0070] Preferably, the mass ratio of bamboo fiber pulp to cigarette paper pulp is 1:(30-50).
[0071] Preferably, during combined pulping, the blade spacing is less than 3mm, and the middle blade pulping method is used.
[0072] Because the slurry contains a high amount of fiber, pressure filtration is used in the processing. Preferably, a filter screen with a mesh size of 200-600 mesh is used to improve the filtration speed.
[0073] S1202: The filtered pulp is fed into a high-speed centrifuge. While centrifuging, clean water is continuously added for washing and further rinsing of the pulp. The pulp discharged from the outlet of the high-speed centrifuge forms a mixed pulp.
[0074] Under the centrifugal force of a high-speed centrifuge, the pulp is subjected to a strong centrifugal force in the high-speed rotating centrifuge. This centrifugal force causes water and light impurities (such as residual chemicals, fine fiber fragments, etc.) in the pulp to be thrown out. At the same time, clean water is continuously added for washing, further rinsing and pulping. After rinsing, the water containing impurities is discharged through the drain, and the washed pulp is discharged from the pulp outlet of the centrifuge as mixed pulp.
[0075] S130: Dewatering and shaping the mixed pulp to form paper.
[0076] As one embodiment, the wire section of a paper machine is used to dewater and shape the mixed pulp. The wire section, also known as the forming device, is an important component of the paper machine. Once the wet paper web is formed on the wire section, the interweaving state of the fibers in the paper is basically fixed, and the basic physical properties of the paper are also determined. The main function of the wire section is to obtain a well-structured wet paper web and to dewater the formed wet paper web to a certain degree of dryness. In the prior art, the wire section includes a wire-laying section, a forming and dewatering section, and a high-pressure differential dewatering section arranged sequentially. The forming and dewatering section includes a forming zone near the wire-laying section and a dewatering zone near the high-pressure differential dewatering section.
[0077] This application does not modify the structure of the paper machine. The mixed pulp passes sequentially through the wire section, the forming and dewatering sections, and the high-pressure differential dewatering section to finally form paper.
[0078] The mixed pulp is dewatered and shaped using the wire section of a paper machine, specifically including:
[0079] On the screen section: The mixed slurry is sprayed onto the screen section, so that the mixed slurry is evenly dispersed on the screen surface and the slurry flow is stable, and the free liquid surface on the screen surface is minimized to reduce large fluctuations.
[0080] Forming and dewatering section: In the forming zone, the pulp is given a certain amount of turbulence, the dewatering rate should not be too high, and the dewatering should be uniform to facilitate uniform paper web formation; in the dewatering zone, the paper web has basically been formed, and the dewatering rate can be gradually increased to remove a large amount of water and form a wet paper web.
[0081] In the high-pressure differential dehydration section: a pressure difference is created across the wet paper web through the suction of a vacuum chamber, compressing the wet paper web and thus dehydrating it. Additionally, when air passes through the internal gaps of the wet paper web, it can carry moisture attached to the fibers into the vacuum chamber for further dehydration, forming paper.
[0082] S140: Drying paper.
[0083] S150: Cut the dried paper into a first preset size. Understandably, the first preset size matches the size of the tobacco end of the cigarette to be sealed.
[0084] S160: The cut paper is sealed at the tobacco end of the cigarette to form the finished cigarette.
[0085] It should be noted that the cigarettes mentioned here are regular cigarettes (non-heated cigarettes). Before the user takes out the cigarette to smoke, the paper sealing the tobacco end needs to be removed.
[0086] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
