Description

Technical Field

[0001] This patent relates to the field of tobacco technology, and specifically to a rotating drum and drying device for drying popping wet pills. Background Art

[0002] Popping beads for cigarettes, commonly known as capsules or scented beads, are 1.5 to 6.5 mm in diameter and are spherical objects made of edible gum. They contain a special scented liquid made from essences, spices, Chinese herbal extracts, and an appropriate amount of solvent. Adding popping beads to cigarettes is a flavor-compensating technology for cigarette flavoring. Adding contents of different properties to popping beads can enrich the aroma of cigarettes, improve the taste of cigarettes, and reduce harmful components in cigarettes. As a new flavoring technology for cigarettes, "popping bead addition" has become an important technical means to build cigarette products with flavor shaping as the core. Therefore, in recent years, with the rapid development of popping bead cigarettes in domestic and foreign markets, tobacco companies' demand for popping bead production has continued to increase.

[0003] The commonly used method for the industrialization of explosive bead preparation is the concentric film-forming method. The concentric nozzle of the dripping machine sprays the wall material solution and the core material solution at different speeds. The wall material wraps a certain amount of core material and then drips into another immiscible coolant to solidify and form. After the explosive beads are drop-formed, they appear soft at this time because the wall material contains a lot of water. They are called explosive bead wet pills. After subsequent curing, cleaning, drying, screening and other processes, the finished explosive beads are finally obtained.

[0004] Currently, the main drying methods include natural air drying and drum drying. Since both the wall and core materials of the pellets are formed from liquid, the wet pellets are soft before drying. During the drum drying process, it is difficult to control their shape and fluidization state, which can easily result in pellets with irregular shapes such as elliptical, convex, and hemispherical shapes, reducing product quality and production efficiency.

[0005] The pellets are fluidized and dried in a rotating drum. Heat exchange between the air and the pellets removes moisture from the pellets. Air flow in the pellet drying process is one of the key factors in achieving an efficient drying process.

[0006] The drum of a rotary drum dryer is typically circular. During the drying process, wet pellets accumulate at the bottom of the drum's arc, creating a thick layer of material. Drying air cannot effectively penetrate the material, hindering heat exchange during drying. Furthermore, the circular drum structure forces the material to move along a fixed circumference at a consistent linear speed, eliminating material tumbling and reducing drying efficiency. Furthermore, the circular structure suffers from inefficient ventilation, relying on surface airflow for heat exchange. This slows moisture migration within the rubber layer, leading to drying cycles of up to 4-6 hours. Existing improvements, such as natural air drying, avoid mechanical damage but are more time-consuming and offer poor environmental control. Furthermore, the addition of forced agitation to the drum can easily damage the pellet structure, leading to core liquid leakage. The industry urgently needs a drying device that can simultaneously optimize fluidized tumbling, hot air penetration efficiency, and damage control to meet the dual requirements of efficiency and quality in industrialized production of explosive pellets. Therefore, a solution for a polygonal rotary drum dryer is urgently needed. Summary of the Invention

[0007] This patent aims to overcome the three major defects of the existing circular drum drying of popping wet pellets, namely, material layer accumulation, low heat exchange efficiency, and high wet pellet damage rate. By designing a rotating drum with a polygonal mesh plate structure and a supporting drying device, this patent provides the following technical solutions:

[0008] In the first aspect, a rotating drum for drying wet pellets of popping beads is provided. The rotating drum includes a material door, a retaining ring, a drum body and a bottom plate. The material door is openably fixed on the retaining ring. The retaining ring and the bottom plate are respectively arranged at both ends of the drum body. The drum body is a polygonal structure. The wet pellets of popping beads are placed on the mesh plate and are dried by rotating the rotating drum. The mesh plate is a breathable structure provided with ventilation holes to promote heat exchange of the wet pellets of popping beads.

[0009] Furthermore, the shape of the barrel can be one or more of a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, a heptagonal prism or an octagonal prism.

[0010] Furthermore, the drum can rotate in both forward and reverse directions.

[0011] Furthermore, the shape of the ventilation holes can be one or more of waist-shaped holes, circular holes, diamond-shaped holes, honeycomb holes or louver-shaped holes.

[0012] Furthermore, the aperture of the ventilation hole is smaller than the diameter of the explosive bead wet pill.

[0013] Furthermore, the diameter of the bursting wet pills is 1.3-3.1 mm, 3.1-4.9 mm or 4.9-6.7 mm.

[0014] Furthermore, the explosive beads wet pills are spheres containing a liquid core.

[0015] Furthermore, the material door and the retaining ring are connected by one or more of a hinge connection, a snap connection, a magnetic connection or a bolt connection.

[0016] Furthermore, the mesh plates are connected in one or more ways: welding connection, mortise and tenon connection, pressure plate connection, quick-release connection or bolt connection.

[0017] In a second aspect, a drying device is provided, comprising the above-mentioned rotating drum and a base for accommodating the rotation of the rotating drum.

[0018] This patent has the following beneficial effects:

[0019] 1. This patent provides a rotating drum and drying device for drying wet pellets, including a material door, a retaining ring, a drum body and a bottom plate. The drum body is surrounded by a mesh plate to form a polygonal structure. The wet pellets are placed on the mesh plate and dried by rotating the drum. The mesh plate is a breathable structure with ventilation holes to promote heat exchange of the wet pellets. When the polygonal structure of the drum body rotates, the linear speed of the edges is significantly higher than that of the plane center, forming a forced convection of "high-speed throwing-low-speed spreading", so that the wet pellets are discrete and evenly rolled, solving the problem of material adhesion in the circular drum and reducing the rate of abnormal shapes.

[0020] 2. In this patent, the polygonal plane enclosed by the mesh plate allows the wet pills to be laid out in a single layer, reducing the thickness of the material layer. The mesh plate is provided with ventilation holes with various hole types. By designing a breathable structure with ventilation holes on the mesh plate, the resistance to hot air penetration is reduced, the synchronous evaporation efficiency of moisture inside and outside the rubber is improved, and the drying cycle is shortened.

[0021] 3. In this patent, the drum can rotate forward and reverse, and the forward and reverse dual-mode drive mechanism provides an adaptive drying path: when rotating forward, the wet pills slide smoothly along the slope to avoid initial mechanical damage; when rotating reversely, the edges and corners scoop up the wet pills and throw them into the air, and strong convection breaks up the late caking, thereby improving drying uniformity.

[0055] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0056] A rotating drum 100 for drying wet pellets, see Figures 1-2 , including a first gear 110, a material door 150, a retaining ring 140, a cylinder body 130 and a bottom plate 120. The retaining ring 140 and the bottom plate 120 are respectively arranged at both ends of the cylinder body 130. The first gear 110 is adjacent to the bottom plate 120 and is arranged at the other end of the bottom plate 120. The retaining ring 140 and the bottom plate 120 are circular structures. The material door 150 can be opened and fixed on the retaining ring 140. The material door 150 is circular and its size is consistent with the size of the circle in the circular ring of the retaining ring 140, so that the material door 150 is fixed on the circular surface of the retaining ring 140 and opens or closes from the circular surface around the fixed point.

[0057] The connection method between the material door 150 and the retaining ring 140 is one or more of hinge connection, snap connection, magnetic connection or bolt connection, which can enable the material door 150 to open and close on the retaining ring 140. This patent is not limited to this.

[0058] In this embodiment, the material door 150 and the retaining ring 140 are connected by a hinge connection, wherein the connecting component is a hinge, one side of the two hinges is fixed to the material door 150 by bolts and the other side is fixed to the annular surface of the retaining ring 140 by bolts.

[0059] The cooperation mode of the retaining ring 140 and the support wheel 260 is one or more of ratchet transmission, groove wheel transmission, cam transmission, flange roller transmission, gear transmission, screw transmission, worm gear transmission, belt transmission, chain transmission or friction wheel transmission.

[0060] In this embodiment, the retaining ring 140 and the support wheel 260 cooperate in a sheave transmission. The retaining ring 140 is provided with raised bars on both sides of the side, with the center providing a rotational track for the support wheel 260, thereby guiding and constraining the support wheel 260 to rotate along the side of the retaining ring 140 and prevent it from deviating.

[0061] The base plate 120 and the driving wheel 230 cooperate in one or more of ratchet drive, groove wheel drive, cam drive, flange roller drive, gear drive, screw drive, worm gear drive, belt drive, chain drive or friction wheel drive.

[0062] In this embodiment, the base plate 120 and the drive wheel 230 cooperate in a sheave transmission. Raised bars are provided around the sides of the base plate 120, with the center providing a rotational track for the drive wheel 230. This guides and constrains the drive wheel 230 from rotating along the sides of the base plate 120, preventing it from deviating and assisting the meshing of the first gear 110 and the second gear to rotate the drum 100.

[0063] The diameter of the first gear 110 is equal to the diameter of the base plate 120 and the retaining ring 140, and the side of the first gear 110 is evenly arranged with teeth in the circumferential direction; the second gear is fixed on the driving mechanism 220, and the driving mechanism 220 is installed in the middle of the side where the driving wheel 230 is located, and the height is equivalent to the radius of the base plate 120. The driving mechanism 220 can drive the second gear to rotate forward or reverse; the diameter of the second gear is smaller, and the side of the second gear is also evenly arranged with teeth in the circumferential direction.

[0064] The shape of the barrel 130 can be one or more of a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, a heptagonal prism or an octagonal prism. This patent is not limited to this. It should be noted that the polygonal structure of the barrel 130 should at least include edges rather than an arc-shaped cross section.

[0065] Specifically, when the polygonal drum 100 rotates, the linear velocity at the corners is much higher than that at the center of the plane, which causes the material to be thrown up at high speed at the corners and spread at a low speed when falling back to the plane, forming forced tumbling. The speed difference breaks the adhesion of the material, making the wet pills more evenly dispersed. The circular drum 100 rolls at a uniform speed, and the material is easy to accumulate into a ball, thereby reducing the airflow penetration resistance and improving the heat exchange efficiency.

[0066] In this embodiment, the barrel 130 is a hexagonal prism, and the side of the barrel 130 is hexagonal. The barrel 130 includes a mesh plate 131 and a ventilation hole 132. The length of the mesh plate 131 is slightly smaller than the length of the frame 240. The six mesh plates 131 enclose the barrel 130, and the bottom of the bottom plate 120 has a hexagonal boss for fixing the side of the barrel 130.

[0067] The ventilation holes 132 are evenly arranged on the mesh plate 131 and are used to allow the bursting beads on the mesh plate 131 to fully exchange heat with the external environment. The shape of the ventilation holes 132 can be one or more of waist-shaped holes, circular holes, diamond-shaped holes, honeycomb holes or louver-shaped holes. In this embodiment, the shape of the ventilation holes 132 is waist-shaped holes, which are long strips with a large air permeability area and are not prone to clogging.

[0068] The connection method of the mesh plates 131 is one or more of welding connection, mortise and tenon connection, pressure plate connection, quick release connection or bolt connection. In this embodiment, six mesh plates 131 are welded into the cylinder body 130, which can ensure the firmness of the connection of the cylinder body 130.

[0069] The bursting beads are spheres containing a liquid core. The diameter of the bursting beads is 1.3-3.1 mm, 3.1-4.9 mm or 4.9-6.7 mm. The specific situation is adjusted according to actual production. The aperture of the ventilation hole 132 is smaller than the diameter of the bursting beads. Before drying, the bursting beads are put into the mesh plate 131 from the material gate 150. During drying, the rotating drum 100 rotates, and the bursting beads move synchronously with the rotating drum 100 and exchange heat with the external environment through the ventilation holes 132.

[0070] Please refer to Figure 3 The base 200 includes a second gear, a driving mechanism 220, a driving wheel 230, a frame 240, an air supply mechanism 250, a supporting wheel 260 and a caster 270. The frame 240 is a rectangular parallelepiped structure. Four casters 270 are provided at the bottom of the frame 240 for fixing or moving the drying device. A cavity is provided inside the frame 240 for accommodating the air supply mechanism 250, the supporting wheel 260, the driving wheel 230, the driving mechanism 220 and the second gear. A receiving groove is provided at the top of the frame 240 for partially placing the rotating drum 100 inside the frame 240. The supporting wheel 260, the driving wheel 230 and the second gear cooperate with the inserted rotating drum 100 part. The driving mechanism 220 is placed in the middle of the side of the frame 240, and the second gear is fixedly set on the driving mechanism 220.

[0071] The driving mechanism 220 is preferably a servo motor or a drive motor.

[0072] The air supply mechanism 250 includes an air outlet and a motor 252. The air outlet supplies air toward the receiving slot. The motor 252 is used to drive the air supply mechanism 250 to supply air. The air supply mechanism 250 can adjust the temperature and size of the air supply through a control mechanism.

[0073] In this embodiment, the air supply mechanism 250 is preferably a fan.

[0074] The accommodating groove is set at the top of the frame 240, specifically, a rectangular opening is opened on the top surface of the frame 240 and a semicircle is opened at the top of the side of the frame 240, and the radius of the semicircle is slightly larger than the radius of the retaining ring 140 and the bottom plate 120 to ensure that the drum 100 can rotate smoothly on the base 200.

[0075] The support wheel 260 includes a first support wheel and a second support wheel, which are respectively fixed to the upper part of one side of the frame 240 and arranged below the accommodating groove; the driving wheel 230 includes a first driving wheel and a second driving wheel, which are respectively fixed to the upper part of the other side of the frame 240 and arranged above the driving mechanism 220, and also arranged below the accommodating groove.

[0076] Please refer to Figure 4 When the drum 100 is installed on the base 200, the drum 100 is placed into the base 200 from the accommodating groove. When the first support wheel and the second support wheel are embedded in the retaining ring 140, the first driving wheel and the second driving wheel are embedded in the bottom plate 120, and the first gear 110 and the second gear are engaged and clamped with each other, the drum 100 is relatively stably placed on the base 200, and the installation of the drum 100 and the base 200 is considered to be completed.

[0077] It is particularly noted that the first gear 110 is at the lowest end of the rotating drum 100, and the bottom plate 120 is closer to the drum body 130 than the first gear 110. Therefore, the corresponding driving wheel 230 should be more protruding than the second gear, and the second gear should be closer to the inner wall of the side of the frame 240, so that the driving wheel 230 and the bottom plate 120, the first gear 110 and the second gear do not interfere with each other.

[0078] The material door 150 is openably fixed on the retaining ring, and the retaining ring and the bottom plate are respectively arranged at both ends of the cylinder body 130, and the cylinder body 130 is a polygonal structure;

[0079] The drum body 130 is enclosed by a mesh plate 131 to form a polygonal structure, and the wet pellets are placed on the mesh plate 131 and rotated and dried by the drum 100;

[0080] The mesh plate 131 is a breathable structure with ventilation holes 132 to promote heat exchange of the popping beads and wet pills.

[0081] The drum 100 can rotate forward and reverse under the drive of the driving mechanism 220. During forward rotation, the second gear connected to the driving mechanism 220 rotates forward synchronously, and the first gear 110 engaged with the second gear rotates forward at the same time. The driving wheel 230 and the supporting wheel 260 rotate forward on the bottom plate 120 and the retaining ring 140 respectively, so that the drum 100 rotates forward as a whole; during reverse rotation, the second gear connected to the driving mechanism 220 rotates reversely synchronously, and the first gear 110 engaged with the second gear rotates reversely at the same time. The driving wheel 230 and the supporting wheel 260 rotate reversely on the bottom plate 120 and the retaining ring 140 respectively, so that the drum 100 rotates reversely as a whole.

[0082] It is particularly noted that when the drum 100 rotates forward, the bursting beads and wet pills slide smoothly along the polygonal inclined surface, which is suitable for initial drying and prevents the bursting beads and wet pills from breaking due to violent collision; when the drum 100 rotates reversely, the bursting beads and wet pills are picked up by the edges and corners and thrown into the air, forming a strong convection tumbling, which is suitable for later drying to break up lumps.
