DETAILED DESCRIPTION

[0031] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present disclosure. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0032] The accompanying drawings illustrate various schematic diagrams of structures according to embodiments of the present disclosure. These figures are not drawn to scale, and for the purpose of clarity, certain details are exaggerated and certain details may be omitted. The shapes of the various regions and layers shown in the figures, as well as their relative sizes and positional relationships, are merely exemplary and may deviate in practice due to manufacturing tolerances or technical limitations. Those skilled in the art may design regions / layers with different shapes, sizes, and relative positions as needed.

[0033] In the context of the present disclosure, when a layer / element is referred to as being "on" another layer / element, it can be directly on the other layer / element or an intervening layer / element may be present therebetween. In addition, if a layer / element is "on" another layer / element in one orientation, it may be "below" the other layer / element when the orientation is reversed.

[0034] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0035] For oral nicotine products, the mainstream "powder filling + non-woven bag packaging" has the following problems:

[0036] 1) The filling powder structure is loose and the release is uneven: The powder is highly mobile in the oral cavity and easily accumulates, making the release rate difficult to accurately control. Especially during the onset phase, problems such as excessive release or insufficient stimulation often occur.

[0037] 2) Poor stability of flavorings and / or active substances: Filling powders are exposed to the air and are very likely to absorb moisture, evaporate or migrate. Especially when containing explosives, flavors, and free base nicotine, their ingredients are easily ineffective due to changes in temperature and humidity.

[0038] 3) The structure and function are single, making it difficult to achieve a multi-level experience: The powder bag structure can only achieve single-flavor, single-stage release, and cannot support innovative sensory experiences such as burst, dual-flavor release, and delayed controlled release.

[0039] 4) The filling process has great limitations: The powder filling process has high requirements on the powder morphology and fluidity. It is difficult to achieve uniform filling when it contains highly viscous fillers or special carriers, which affects product consistency and production capacity.

[0040] In summary, although powder-filled bagged oral preparations are currently the mainstream products, they have obvious technical bottlenecks in product structure, release control, sensory experience and industry expansion, and urgently need innovative breakthroughs.

[0041] In order to solve the problems of loose filling powder structure, uneven release and poor stability in bagged oral products, in an optional embodiment, please refer to Figure 1 The provided manufacturing equipment for oral products is used to prepare oral products containing active substances and / or flavorings, including: a feeding unit 10, used to provide a substrate; an application unit 20, arranged downstream of the feeding unit 10, used to apply a filler including active substances and / or flavorings to form a filling layer stacked with the substrate; and a coating unit 30, arranged downstream of the feeding unit 10, used to coat to form a coating layer stacked with the substrate and the filling layer to obtain the oral product.

[0042] In some embodiments, the material applying unit 20 and the film coating unit 30 may also be used in combination with the material applying unit 20 according to actual needs.

[0043] With the movement direction of the substrate as a reference, for any unit, the upstream is the incoming end and the downstream is the outgoing end. The feeding unit 10 is located upstream of the manufacturing equipment and serves as a feeding device for providing the initial substrate. In some embodiments, the feeding unit 10 can use a feeding wheel group or an unwinding wheel group to unwind the rolled substrate and then provide it to the feeding unit 20 and the laminating unit 30 located at the downstream end of the feeding unit 10; the feeding unit 10 can ensure that the substrate stably enters the feeding unit 20 and the laminating unit 30, and maintains the tension stability of the substrate.

[0044] The substrate is the base layer of the stacked oral product, serving as the basis for supporting the filling layer and the coating layer; in some embodiments, the substrate is a non-woven fabric, a hydrophobic fabric or other types of composite fabrics, and the coating layer is a non-woven fabric, a hydrophobic fabric or other types of composite fabrics. Non-woven fabrics, also known as non-woven fabrics, are sheet-like or film-like materials formed by directly bonding or entangled fibers together by mechanical, thermal bonding or chemical methods, and have certain permeability. Hydrophobic fabrics are fabrics with a surface that repels liquid water. It can be made of synthetic fibers that have a certain hydrophobicity, or it can be a composite fabric with a hydrophobic or waterproof coating (such as fluorine-containing compounds, silanes, waxes) formed on the surface of some fabrics (including non-woven fabrics) to prevent the rapid penetration of liquid water.

[0045] The applying unit 20 is used to apply filler to form a filling layer. Through the applying unit 20, one or more layers of filling layer material can be evenly and quantitatively applied on the substrate. The applying width can match the finished product specifications of the oral product, or can be selected according to the width of the substrate or actual conditions.

[0046] In some embodiments, the filling layer may include functional components, and the filling layer provides functional components for the oral product. In some embodiments, the functional components include flavorings and / or active substances. The active substance may be nicotine and / or nicotine derivatives, wherein the nicotine derivatives may be nicotine salts and nicotine containing substituents, such as nicotine tartrate, nicotine lactate, hexamethyl nicotine, etc.; the flavorings may be spices, aerated particles, cooling agents and other components used to adjust the taste, release rate or other physical and chemical properties of the oral product. The functional components may also be other substances, such as caffeine, amino acids, vitamins, plant extracts, etc., which are not limited here. In some embodiments, the filling layer may also include components for facilitating molding, facilitating production, or improving taste, which are not limited here, and the user can choose the configuration according to the actual situation.

[0047] The laminating unit 30 is used to laminate a layer of laminating material onto the material input from its input end. In some embodiments, the laminating unit 30 is used to provide a laminating process, whereby a laminating material or laminating cloth is applied to the material input from the input end by pressurizing, bonding, or heating to form a laminating layer. This process can be used to laminate non-woven fabric, closed fabric, or other materials onto a filling layer, substrate, or other laminating layer. It supports multi-layer lamination and the replacement of single-layer fabric, composite fabric, and functional film (such as hydrophobic fabric). The laminating layer formed by the laminating unit 30, together with the substrate and filling layer, can form a stable laminated structure and can also control or adjust the release of active substances and / or flavoring agents from the filling layer.

[0048] It should be noted that the application unit 20 includes at least one application module, and one application module can be selectively used to form at least one filling layer of each oral product; the coating unit 30 includes at least one coating module, and one coating module can be selectively used to form at least one coating layer of each oral product; that is, according to design and functional requirements, each oral product can include one or more filling layers and coating layers. In order to meet the manufacturing requirements of the oral product, when assembling the manufacturing equipment, the application unit 20 can include one or more modular application modules, and the coating unit 30 can include one or more modular coating modules. , the number of feeding modules and coating modules needs to match the maximum stacking number of the oral product. For example, the maximum number of filling layers and coating layers of a certain oral product are both 3. Then, when using the commonly used unidirectional single-pass feeding modules and coating modules, the feeding unit 20 needs to include 3 feeding modules, and the coating unit 30 needs to include 3 coating modules; if bidirectional multi-pass feeding modules and coating modules are used, by driving the substrate to move back and forth, multiple filling layers can be formed in one feeding module, or multiple coating layers can be formed in one coating module. Then, the feeding unit 20 can include only one feeding module, and the coating unit 30 can include only one coating module. In addition, when the number of feeding modules and coating modules is greater than the number of stacking layers of the oral product currently to be manufactured, only some of the feeding modules and coating modules need to be selectively used; for example, when manufacturing a three-layer oral product of substrate-filling layer-coating layer, only one feeding module and one coating module in the manufacturing equipment need to be used; in this way, a set of manufacturing equipment can be used to manufacture a variety of oral products with different stacking structures, thereby broadening the applicability of the manufacturing equipment.

[0049] The positional arrangement of the feeding module and the coating module determines the stacking order of the filling layer and the coating layer in the stacked oral product. The more common situation is that the filling layer and the coating layer are stacked alternately in sequence, that is, there is a coating layer between two adjacent filling layers, there is a filling layer between two adjacent coating layers, or there is a filling layer between the substrate and the nearest adjacent coating layer; in addition, multiple filling layers can also be stacked together, for example, at least two filling layers can be stacked between the substrate and the nearest coating layer, or between two adjacent coating layers.

[0050] Corresponding to the above-mentioned oral products, in some embodiments, please refer to Figure 2 In the manufacturing equipment provided, at least one applying module A2 is arranged between a coating module A3 and the feeding unit 10, and is used to form at least one filling layer between the coating layer and the substrate of the oral product; when the coating unit 30 has at least two coating modules A3, at least one applying module A2 is arranged between two adjacent coating modules A3, and is used to form at least one filling layer between two adjacent coating layers of the oral product.

[0051] In other embodiments, see Figure 3 The manufacturing equipment provided is that the applying unit 20 includes N applying modules A2, and the coating unit 30 includes N coating modules A3, where N is a positive integer; the applying modules A2 and the coating modules A3 are alternately arranged one by one downstream of the feeding unit 10; the applying module A2 is used to apply filler to the substrate or the coating layer to form a filling layer; the coating module A3 is used to coat the surface of the filling layer to form a coating layer.

[0052] Therefore, the embodiment of the present disclosure provides a manufacturing device for oral products, including multiple modular functional units, wherein a substrate is provided by a feeding unit 10, a feeding unit 20 applies a filler including an active substance and / or a flavoring to form a filling layer stacked with the substrate, and a coating unit 30 coats to form a coating layer stacked with the substrate and the filling layer; the feeding unit 20 and the coating unit 30 are modularly designed, and through at least one feeding module and at least one coating module, a stacked oral product with a stable structure including at least one filling layer and at least one coating layer can be formed on the substrate, thereby overcoming the problem of loose filling powder in bagged oral products, effectively improving the ingredient retention rate and consistency of the filling layer, thereby obtaining an oral product with a more stable filling layer structure and better uniformity in the release of filling layer materials.

[0053] In addition, according to the stacking structure of the oral product, the modularly designed application unit 20 can be configured with multiple application modules, and the coating unit 30 can be configured with multiple coating modules, and supports the selective use of one or more application modules and coating modules. Combined with the material of the base material and the coating layer, and the selection of the filling layer components, a variety of oral products with different stacking structures and different flavors can be obtained to meet various usage requirements.

[0054] In some embodiments, the application module can be a coating module or a printing module; the coating module is used to provide a coating process to form a filling layer on one or both sides of the substrate. Coating is a process of coating a paste or molten filling material on a substrate to form a filling layer. The coating module can be a roller coating module, an air knife coating module, a knife roller coating module, and a die groove coating module, etc.; the printing module is a processing module that uses a filler containing active substances and / or flavorings as "ink" and "prints" a new filling layer on a substrate, a filling layer, or a coating layer according to a certain pattern; the printing module can be a screen printing module or an inkjet printing module, etc.

[0055] In some embodiments, the laminating module may use a laminating wheel set or a laminating machine to press the laminating material onto the filling layer through a roller or a rolling wheel to form a laminating layer.

[0056] In some embodiments, the application module and the laminating module may incorporate heating functions to cure or dry the filling layer and to shape the laminating layer. For example, a preheating application module can be used to cure or pre-cure the filling layer while it is being formed; a preheating laminating module can be used to enhance the bond strength between the laminating layer and the filling layer while forming the laminating layer.

[0057] In some embodiments, see Figure 4 The manufacturing equipment also includes a heating unit 40, which is arranged downstream of the feeding module or the coating module, and is used to dry or cure the filling layer and / or the coating layer; compared with the feeding module and the coating module with preheating function, the independent heating unit 40 can flexibly set the heating temperature and heating time, thereby improving the drying and curing effect of the filling layer, or improving the shaping effect of the coating layer.

[0058] In some embodiments, the heating unit 40 includes multiple heating devices, and the outlet end of each feeding module and each coating module is individually provided with at least one heating device; in this way, after any filling layer or coating layer is formed, it can be sent to the heating device for drying, curing or shaping as soon as possible to obtain a better heating effect; wherein, the heating conditions of each heating device are configured to be independently controllable to meet the heating requirements of different filling layers or coating layers.

[0059] In some embodiments, the heating device includes a tunnel furnace, and the heating temperature of the tunnel furnace is not lower than room temperature and not higher than 180°C. Excessively high temperature will cause excessive volatilization of active substances and / or flavorings, affecting product quality; the heating device equipped with a tunnel furnace has the characteristics of a wide temperature control range, and can adapt to different heating requirements through segmented heating and drying.

[0060] In some embodiments, see Figure 4 The manufacturing equipment also includes a spraying unit 50, which is arranged downstream of the feeding unit and is used to apply a liquid material to the surface of at least one of the substrate, the filling layer and the coating layer; the liquid material can be a composite solution used to flavor the semi-finished oral product, such as a composite solution of flavor and nicotine, which can be formulated according to actual needs. The embodiments of the present disclosure do not impose specific restrictions on its components.

[0061] It should be noted that the spray unit 50 is selectively used to flavor some types of oral products, and is not mandatory for flavoring all types of oral products; in some embodiments, the spray unit 50 may include a double spray module, which can spray liquid materials on the upper and lower surfaces of the target film layer at the same time, thereby achieving a better flavoring effect; at the same time, thanks to the ability of the double spray module to precisely adjust the spraying volume and the sheet-like form of the stacked oral product, it can dry naturally after the double spraying is completed, and will not produce obvious adhesion or volatilization loss compared to bagged products.

[0062] It should be noted that the dual-spray module is an independent mechanical module that can be installed at any section of the manufacturing equipment production line as long as space is reserved for its arrangement. According to the product design, liquid materials can be sprayed on the surface of at least one of the substrate, filling layer and coating layer; for example, if the dual-spray module is arranged downstream of the last coating module, liquid materials can be sprayed on the surface of the semi-finished product of the oral product; if the dual-spray module is arranged upstream of any coating module, liquid materials can be sprayed on the surface of the filling layer.

[0063] In some embodiments, see Figure 4 The manufacturing equipment also includes a collecting unit 60, which is arranged at the downstream end of the manufacturing equipment and is used to collect the finished oral products; the collecting unit 60 can collect the finished oral products by slicing or by rolling; for rolling collection, the finished oral products are rolled into rolls and then stored, packaged and inspected for quality; for slicing collection, the continuous finished products can be sliced ​​and cut according to the set specifications to form oral products of standard size for storage, packaging and quality inspection; slicing collection has the characteristics of high precision and can adapt to finished products of sheet-like oral products of different thicknesses and specifications.

[0064] In some embodiments, see Figure 4 The manufacturing equipment also includes a power unit 70, which is configured to drive the substrate to move between the various processing units of the manufacturing equipment; the stacked oral products are often manufactured using a rolled strip substrate, which can be unwound by a feeding wheel group. Under the action of the power unit, the strip substrate moves between the feeding unit, the coating unit, the heating unit and the spraying unit to form the corresponding filling layer and coating layer, and complete the heating and semi-finished product spraying.

[0065] In some embodiments, the power unit 70 includes a traction wheel group and a tension wheel group; the traction wheel group is configured to pull the strip substrate provided by the supply wheel group to move between the processing units, and the tension wheel group is configured to resist the strip substrate and adjust the tension of the strip substrate.

[0066] It should be noted that Figure 4 The arrangement of the application unit 20, the coating unit 30, the heating unit 40, the spraying unit 50 and the power unit 70 is only an example to show that the manufacturing equipment includes the above-mentioned units, rather than to clearly define the arrangement position and order of the units.

[0067] In summary, the embodiments of the present disclosure provide a modularly designed manufacturing device for stacked sheet-like oral products, which can use one or more feeding modules and coating modules according to product requirements, is compatible with different types of substrates, coating layers and filling layers with different formulas, and has industrial continuous production capabilities to meet the production needs of high efficiency, low manpower and high consistency.

[0068] In order to explain the above solution more intuitively, in the following embodiments, an optional manufacturing device and the stacked structure of the oral product manufactured by using the manufacturing device will be further explained.

[0069] See also Figure 5 The feeding unit 20 of the manufacturing equipment includes a first feeding module 21 and a second feeding module 22, and the coating unit 30 includes a first coating module 31 and a second coating module 32. The first feeding module 21 is arranged between the feeding unit 10 and the first coating module 31, and the second feeding module 22 is arranged between the first coating module 31 and the second coating module 32.

[0070] All the application modules can be coating modules, and the coating module can be one of roller coating, air knife coating, knife roller coating and die slot coating. Taking the first application module 21 as an example, Figure 5 What is shown is a knife roller coating module, including a coating roller 2A for carrying a substrate; a hopper 2B for storing materials corresponding to the filling layer, and cooperating with the coating roller 2A to coat the materials onto the substrate; a coating knife 2C for removing filler materials on the substrate that exceed a set thickness to form a filling layer; the coating module can achieve uniform quantitative coating of the filler material, and can also support wide-width continuous application of high-viscosity slurries or powder suspensions, and the coating amount is adjustable, and the coating width matches the finished product specifications; the structure of the second application module 22 is the same as that of the first application module 21, and will not be repeated.

[0071] All laminating modules can adopt a laminating wheel group. Taking the first laminating module 31 as an example, it includes a laminating wheel 3A, a supporting wheel 3B and a roller 3C. The finished roll of the laminating material is sleeved on the laminating wheel 3A. After being unrolled by the laminating wheel 3A, the laminating material is guided to the roller 3C through the supporting wheel 3B, and then pressed on the filling layer by the roller 3C to form a laminating layer; in addition, the roller 3C can have a preheating function, which helps to improve the bonding strength of the laminating layer.

[0072] The manufacturing equipment further comprises a heating unit 40, such as Figure 5As shown, the heating unit 40 specifically includes: a first heating device 41, arranged between the first feeding module 21 and the first coating module 31, for drying or curing the filling layer formed by the first feeding module 21; a second heating device 42, arranged between the first coating module 31 and the second feeding module 22, for shaping the coating layer formed by the first coating module 31; a third heating device 43, arranged between the second feeding module 22 and the second coating module 32, for drying or pre-curing the filling layer formed by the second feeding module 22; a fourth heating device 44, arranged at the outlet side of the second coating module 32, for shaping the coating layer formed by the second coating module 32, and / or curing the filling layer formed by the second feeding module 22.

[0073] All heating devices can use the same heating equipment and set the same or different temperature control ranges according to needs. Taking the first heating device 41 as an example, it can include a tunnel furnace 4A, which is provided with a heating module 4B for providing tunnel-type heating capabilities with independent temperature control in multiple zones, which can be used for curing the filling layer, shaping after lamination, and volatilization control of the surface solution. The tunnel furnace 4A is also provided with a convection fan 4C and an exhaust hole 4D, which are used to control the heating environment in the furnace, achieve uniform heating and efficient heat transfer, so as to improve the drying, curing or shaping effect; all heating devices have the characteristics of a wide temperature control range (such as room temperature to 180°C), and are adapted to different structural requirements through segmented heating and drying.

[0074] The manufacturing equipment also includes a spray unit 50 for applying liquid material to the semi-finished oral product; the spray unit 50 adopts a dual spray module, which is an atomizing spray device that supports multi-channel independent control and can accurately set the spraying dose, pressure and position to achieve functional enhancement or flavor differentiation of the oral product. For example, different flavors of solutions can be sprayed on the surface of different positions of the oral product to provide a mixed flavor, or the surface of the oral product can be flavored; the dual spray module can be set at the outlet side of the fourth heating device 44; it needs to be explained The spray unit 50 is selectively used to flavor some types of oral products, and it is not necessary to flavor all types of oral products. At the same time, as mentioned above, spraying nicotine / flavoring on the packaged surface of bagged oral products is difficult to accurately control the dosage, and there is a problem of adhesion or volatilization loss easily caused by no further drying process after spraying. The double-spray module can accurately adjust the spraying amount and the sheet shape of the stacked oral products, and can dry naturally after the double spraying is completed, and will not cause obvious adhesion or volatilization loss compared to bagged products.

[0075] The manufacturing device also includes a collecting unit 60, see Figure 5The collecting unit 60 includes a slicing module 62 and a collecting module 61; the slicing module 62 is used to cut the continuous semi-finished oral products into finished oral products of a set shape and size; the collecting module 61 is arranged at the outlet end of the slicing module 62, and the collecting module 61 includes a receiving wheel group 611 and / or a receiving frame 612, the receiving wheel group 611 is used to roll up the oral products, and the receiving frame 612 is used to accommodate flatly stacked oral products; after the collecting unit 60 collects the finished oral products, subsequent storage, packaging and quality inspection are carried out.

[0076] See also Figure 5 The slicing module 62 includes: a first cutting group 621, which is used to cut the continuous semi-finished oral product in a first direction; the first direction is the direction of substrate transmission; a second cutting group 622, which is arranged downstream of the first cutting group 621, and is used to slice the oral product along a second direction, and the second direction is perpendicular to the first direction; a material receiving frame 612 is arranged downstream of the second cutting group 622, and is used to collect the sliced ​​oral product finished products.

[0077] Specifically, since the first direction is the direction of substrate transport, the first cutter assembly 621 can be considered a vertical cutter assembly, used to cut the oral product into strips along the transport direction. The second direction is a horizontal direction perpendicular to the transport direction, and the corresponding second cutter assembly 622 can be considered a transverse cutter assembly, used to cut the strip oral product into standard-sized slices. The sliced ​​oral products can be stored in a flat sheet storage manner via the receiving frame 612. The first and second directions are interchangeable; to facilitate slicing and collection, a conveyor belt can be provided at the slicing module 62 to achieve slicing and transportation of the finished oral products.

[0078] In some embodiments, only the first cutter group 621 may be used to cut the continuous semi-finished oral product in the first direction to obtain strip-shaped oral products, which are then collected by the receiving wheel group 611.

[0079] The manufacturing equipment also includes a power unit 70, see Figure 5 The power unit 70 specifically includes: a first traction wheel group 71, which is arranged between the first feeding module 21 and the first heating device 41, and is used to pull the substrate; a second traction wheel group 72, which is arranged between the first heating device 41 and the first coating module 31, and is used to pull the substrate; a third traction wheel group 73, which is arranged between the second feeding module 22 and the third heating device 43, and is used to pull the substrate; a fourth traction wheel group 74, which is arranged between the third heating device 43 and the second coating module 32, and is used to pull the substrate; a fifth traction wheel group 75, which is arranged at the outlet side of the second coating module 32, and is used to pull the oral product; the traction wheel groups arranged at the above-mentioned key nodes are used to drive the overall operation of the strip substrate and cooperate with each process to complete the process synchronization control, and coordinate the line speed and beat of the whole process.

[0080] The power unit 70 also includes: a first tension wheel group 76, which is arranged between the feeding unit 10 and the first feeding module 21, and is used to control the tension of the substrate; a second tension wheel group 77, which is arranged between the second heating device 42 and the second feeding module 22, and is used to control the tension of the substrate; each tension wheel group is arranged at a transition position between the layers of the oral product, and is used to control the tension of different film materials or intermediate structures during operation, to prevent the film materials from wrinkling or shifting, and to ensure accurate lamination positioning; the first tension wheel group 76 and the second tension wheel group 77 can also be provided with automatic tension feedback to improve the accuracy of tension control.

[0081] It should be noted that Figure 5 The manufacturing equipment includes two feeding modules and two coating modules. By selectively using the above modules, oral products with 3 to 5 layers can be prepared. For example, by using the feeding unit 10, the first feeding module 21 and the first coating module 31, an oral product with a three-layer structure can be prepared; by using the feeding unit 10, the first feeding module 21, the second feeding module 22 and the second coating module 32, an oral product with a four-layer structure can be prepared; by using the feeding unit 10, the first feeding module 21, the first coating module 31, the second feeding module 22 and the second coating module 32, an oral product with a five-layer structure can be prepared. The components of the active substance and / or flavoring agent of each filling layer can be the same or different, and the coating material of each coating layer can also be the same or different. In this way, oral products with different numbers of layers, different flavors and different release effects can be obtained using the same set of manufacturing equipment, and can be flexibly configured according to product design requirements. If it is necessary to manufacture oral products with more than five layers, it can also be Figure 5 This can be achieved by further adding a feeding module, a laminating module and a heating device to the manufacturing equipment provided.

[0082] In the following examples, Figure 5 Taking the manufacturing equipment provided as an example, the manufacturing process of the manufacturing equipment is introduced in combination with several typical stacked oral products.

[0083] Example 1: Single-layer oral product.

[0084] The main modules in use include: a feeding unit 10 , a first material applying module 21 and a first film coating module 31 .

[0085] 1) A substrate BL is provided by a feeding unit 10 (such as a feeding wheel).

[0086] 2) The coating roller 2A and the coating knife 2C of the first material applying module 21 are used to coat the hydrophobic cloth to form a first filling layer CL1 ; the components of the first filling layer CL1 include a film-forming substance, an active substance, and a flavoring agent.

[0087] 3) The coated substrate BL enters the first heating device 41 to lightly dry the first filling layer CL1. The heating temperature of the first heating device 41 can be set to 80°C to 90°C.

[0088] 4) The first coating module 31 is used to coat a layer of non-woven fabric on the first filling layer CL1 as the first coating layer FL1 .

[0089] 5) The first filling layer CL1 is completely solidified and the first coating layer FL1 is fixed by the second heating device 42 ; the heating temperature of the second heating device 42 can be set to 95° C. to 105° C.

[0090] 6) Drying is performed by the third heating device 43 to obtain Figure 6A The drying temperature of the single-layer oral product shown is 90° C. to 100° C. It should be noted that the single-layer here refers to only one filling layer, not that the total number of layers in the product is only one.

[0091] 7) The single-layer oral product is collected by the collecting wheel set 611 or the collecting frame 612.

[0092] All traction wheel sets in the production process use medium tension, such as 0.15kgf / cm~0.25kgf / cm.

[0094] Example 2: Single-layer oral product with added material.

[0095] The main modules used include: a feeding unit 10, a first applying module 21, a first coating module 31 and a spraying unit 50 (double spraying module).

[0096] 1) A nonwoven fabric is provided as a base material BL by the feeding unit 10 .

The coating speed can be controlled at 1.0 m / min to 2.0 m / min, so that the coating thickness is controlled at 350 μm to 500 μm.

[0098] 3) The coated substrate BL enters the first heating device 41 , where the heating temperature can be controlled at 80° C. to 90° C., which is only used to dry the bottom layer (substrate BL).

[0099] 4) A non-woven fabric is coated on the first filling layer CL1 as the first coating layer FL1 by the first coating module 31. After the non-woven fabric coating is completed, the substrate BL directly passes through the second heating device 42 without heating to avoid volatilization of the API.

[0100] 5) The third heating device 43 or the fourth heating device 44 is used for low-temperature auxiliary drying, and the heating temperature does not exceed 90°C.

[0101] 6) Use the spraying unit 50 to spray the feeding solution on both sides, and obtain the following after natural drying: Figure 6B The double-spray spray rate of the single-layer oral product shown is controlled at 1.5-2.5 g / min / m to control the penetration of the composite solution and avoid accumulation.

[0102] 7) The single-layer oral product is collected by the winding unit 61 or the slicing unit 62 through the receiving wheel group 611 or the receiving frame 612.

[0103] All traction wheel sets in the production process use medium tension, such as 0.20kgf / cm~0.28kgf / cm.

[0104] The single-layer oral product with added materials manufactured by using the above-mentioned module has a stacked structure of three layers: first filling layer CL1-first filling layer CL1-first coating layer FL1. Compared with the oral product in Example 1, since no second heating device is used, low-temperature auxiliary drying is adopted and a spraying unit is used for adding materials, the API of the final product volatilizes less and the taste can be richer.

[0105] Example 3: Double-layer oral product.

[0106] The main modules in use include: a feeding unit 10 , a first material applying module 21 , a first film covering module 31 , a second material applying module 22 and a second film covering module 32 .

[0107] 1) The substrate BL is provided by the feeding unit 10 .

[0108] 2) The coating roller 2A and the coating knife 2C of the first applying module 21 are used to apply a first filling layer CL1 on the non-woven fabric; the first filling layer CL1 is a quick-release type, and its components include a first film-forming substance, a first active substance, and a first flavoring agent. The coating speed can be controlled at 1.2 m / min to 2.0 m / min, and the coating thickness can be controlled at 200 μm to 350 μm.

[0110] 4) The first coating module 31 is used to coat a layer of non-woven fabric on the first filling layer CL1 as the first coating layer FL1 .

The coating speed can be controlled at 1.2 m / min to 2.0 m / min, and the coating thickness can be controlled at 200 μm to 350 μm.

[0113] 7) After coating, the film enters the third heating device 43 for semi-curing, and the heating temperature can be controlled at 100°C to 110°C.

[0114] 8) The second laminating module 32 laminates the semi-cured second filling layer CL2 with a non-woven fabric to form a second laminating layer FL2.

[0115] 9) After lamination, the film enters the fourth heating device 44 for curing, shaping and drying. The heating temperature can be controlled at 100°C to 110°C to obtain the following: Figure 6C The double-layer oral product shown. It should be noted that the double-layer here means that the oral product includes two filling layers.

[0116] 10) The double-layer oral product is collected by the collecting wheel set 611 or the collecting frame 612.

[0117] All traction wheel sets in the production process use medium to high tension, such as 0.25kgf / cm to 0.35kgf / cm.

[0118] In some embodiments, a spray unit 50 can be optionally used to spray the composite solution on both sides of the double-layer oral product to enhance the function of the back end. If used, the spray rate can be controlled at 1.0-1.5 g / min / m.

[0119] The double-layered oral product manufactured using this module has a five-layered structure. The first layer, base material BL, is a nonwoven fabric. The second layer, first filling layer CL1, is a rapid-release filling layer, using a fast-dissolving filler to create an initial release. The third layer, first film layer FL1, is a nonwoven fabric barrier. The fourth layer, second coating layer, maintains a sustained release with a distinct release rhythm. The fifth layer, second film layer FL2, is sealed with nonwoven fabric. Overall, the double-layered oral product, with its two coating layers and two layers of film-coated nonwoven fabric, creates dual sustained-release zones, making it suitable for oral products requiring both initial and medium- to long-term sustained release.

[0120] Example 4: Multi-flavor double-layer oral product

[0121] The main modules in use include: a feeding unit 10 , a first material applying module 21 , a first film covering module 31 , a second material applying module 22 and a second film covering module 32 .

[0122] 1) A nonwoven fabric is provided as a base material BL by the feeding unit 10 .

[0125] 4) Using the first coating module 31 , a layer of hydrophobic cloth is coated on the first filling layer CL1 as the first coating layer FL1 .

[0126] 5) The coated substrate BL enters the second heating device 42 for shaping. The heating temperature is controlled at 105° C. to 115° C. Micro-temperature division can be set to improve temperature control accuracy.

[0127] 6) The coating roller 2A and the coating knife 2C of the second applying module 22 are used to apply a second filling layer CL2 on the shaped first coating layer FL1; the components of the second filling layer CL2 include a second film-forming substance, a second active substance, and a second flavoring agent; the coating speed can be controlled to be 1.2 m / min to 2.0 m / min, and the coating thickness can be controlled to be 200 μm to 300 μm.

[0128] 7) After coating, the film enters the third heating device 43 for semi-curing, and the heating temperature can be controlled at 100°C to 110°C.

[0129] 8) The second laminating module 32 laminates the semi-cured second filling layer CL2 with a non-woven fabric to form a second laminating layer FL2.

[0130] 9) After lamination, the film enters the fourth heating device 44 for curing, shaping and drying. The heating temperature can be controlled at 100°C to 110°C to obtain the following: Figure 6D The multi-flavor double-layer oral preparation shown.

[0131] 10) The multi-flavor double-layer oral product is collected by the collecting wheel set 611 or the collecting frame 612.

[0132] All traction wheel sets in the production process use high tension, such as 0.28kgf / cm~0.38kgf / cm.

[0133] In some embodiments, a dual-spray module 50 can be used to achieve multiple flavor adjustments. In this case, the same filler layer composition can be used for both coatings. The dual-spray module 50 sprays different flavors of essence at different locations on the surface to achieve localized flavor variation and surface flavor adjustment. If a dual-spray module 50 is used, the spray rate can be controlled at 1.2 to 2.0 g / min / m.

[0134] The multi-flavor double-layer oral product manufactured by using the above-mentioned module has a five-layer stacked structure. The base material BL of the first layer is non-woven fabric. The first filling layer CL1 of the second layer and the second filling layer CL2 of the fourth layer are separated by the hydrophobic fabric of the third layer: the first covering layer FL1 to form a "release delay zone", so that the front taste and the back taste enter the mouth in stages, which is suitable for enhancing the flavor level and interesting experience. The second covering layer FL2 of the fifth layer is sealed with non-woven fabric. In short, the multi-flavor double-layer oral product can meet the needs of multi-stage flavor release by arranging the two-flavor fillers in layers or in parallel, and is suitable for innovative experience products.

[0135] Example 5: Continuous double-layer oral product

[0136] The main modules used include: a feeding unit 10, a first feeding module 21, a second feeding module 22 and a second coating module 32; the feeding unit 10 provides a non-woven fabric as a base material BL, and then the first feeding module 21 and the second feeding module 22 form a first filling layer CL1 and a second filling layer CL2 stacked together on the base material BL, and then the second coating module 32 forms a first coating layer CL1 for capping, so as to obtain the following: Figure 6E The oral product shown; therefore, the main difference between the oral product of Example 5 and Examples 3 and 4 is that the first filling layer CL1 and the second filling layer CL2 are not separated by a coating layer but are directly stacked together, so there is no need to use the first coating module 31. For other steps and processes, please refer to the relevant contents of Examples 3 and 4, which will not be repeated here.
