Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and specifically to a raw material drying device for cosmetic production. Background Technology

[0002] In cosmetic production, some raw materials often contain high moisture content during extraction, compounding, or pretreatment stages. To improve raw material stability and facilitate subsequent formulation and storage, a drying step is usually incorporated into the process to reduce their moisture content. Rotary drum dryers are widely used in cosmetic raw material drying due to their simple structure, large processing capacity, and strong adaptability. These machines utilize the continuous rotation of the drum to constantly tumble the raw materials inside and ensure full contact with the heating medium, thereby achieving moisture evaporation.

[0003] In existing drum dryers, the drying time of raw materials is mainly adjusted by controlling the drum's rotation speed and tilt angle. A higher rotation speed results in a shorter residence time for the material inside the drum; a lower rotation speed results in a longer residence time. However, in actual use, the initial moisture content, particle size, thermosensitive properties, and loading of raw materials vary, making it difficult to achieve a uniform drying effect at a fixed rotation speed. To extend the drying time, the rotation speed is usually reduced to increase the residence time of the material inside the drum. However, a lower rotation speed reduces the frequency of material tumbling, making it prone to accumulation at the bottom of the drum or in localized areas. This leads to uneven tumbling and uneven heating, resulting in incomplete drying or localized over-drying, affecting the stability of subsequent batching and product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a raw material drying apparatus for cosmetic production, aiming to alleviate the aforementioned problems to at least some extent.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A raw material drying device for cosmetic production, comprising: A drying cylinder, wherein a roller is provided inside the drying cylinder and multiple air ports are provided on the roller; Multiple partition rings are disposed inside the drum, and the multiple partition rings are arranged at equal intervals along the axial direction of the drum; An air inlet pipe is provided on the drying cylinder, the air inlet pipe extends into the interior of the cylinder, the partition ring is fixed on the air inlet pipe, and multiple drying ports are provided on the air inlet pipe; A driving component located between the drying cylinder and the drum is used to drive the drum to rotate inside the drying cylinder; A rotating component located between the drying cylinder and the air inlet pipe is used to intermittently rotate the air inlet pipe.

[0006] Preferably, the roller has multiple discharge ports a, the drying cylinder has discharge ports b corresponding to the discharge ports a, and a feed pipe is fixed on the drying cylinder, the feed pipe being connected to the roller.

[0007] Preferably, the driving component includes a gear a connected to the end of the drum, a motor a connected to the drying drum, and a gear b connected to the output shaft of the motor a and meshing with the gear a.

[0008] Preferably, the rotating component includes a gear c fixed to the air inlet pipe, a motor b connected to the drying cylinder, and a gear c fixed to the output shaft of the motor b, with the two gears c meshing with each other.

[0009] Preferably, the inner wall of the roller is connected to a plurality of paddles.

[0010] Preferably, the intake pipe is provided with an extension pipe, which is rotatably sleeved inside the intake pipe.

[0011] In summary, the present invention has the following main beneficial effects: This device divides the interior of the drum into multiple chambers by setting a partition ring around the outer periphery of the air inlet pipe. The intermittent rotation of the air inlet pipe controls the phased flow of the raw material, ensuring that each batch of material remains stationary within its chamber for targeted heating, thus effectively extending the drying residence time. Simultaneously, the drum rotates continuously at a low speed, causing the baffles on the inner wall to agitate the material, preventing accumulation or uneven heating due to prolonged residence. This structure achieves a controllable extension of drying time without relying on reducing the rotation speed, balancing material agitation with thorough drying, improving drying uniformity and process adaptability, and solving the problems of easy accumulation and insufficient agitation in traditional drum dryers at low speeds.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] refer to Figures 1-4 This embodiment provides a raw material drying device for cosmetic production, including a drying cylinder 100, a drum 101, an air inlet pipe 104, a separator ring 103, a driving component, and a rotating component.

[0016] The drying cylinder 100 is a monolithic structure with a support mechanism and a rotating interface installed at both ends to accommodate and support the rotation of the drum 101. The drying cylinder 100 is inclined at a certain angle relative to the horizontal plane to promote axial sliding of the material during the drying process.

[0017] The roller 101 is located inside the drying cylinder 100 and can rotate around its axis. Multiple air ports 102 are provided on the outer wall of the roller 101. The roller 101 is driven to rotate by a drive component located at one end, and the rotational speed is adjusted to regulate the tumbling frequency of the raw materials inside the cylinder.

[0018] The air inlet pipe 104 is arranged along the axis of the drum 101, and its distal end is connected to a hot air source. The air inlet pipe 104 is driven by a rotating component. Multiple drying ports 105 are provided on the wall of the air inlet pipe 104 for spraying hot air into each chamber in segments. The partition rings 103 are fixedly installed at equal intervals on the outer periphery of the air inlet pipe 104, dividing the interior of the drum 101 into multiple chambers, each chamber being used to hold a certain amount of raw material.

[0019] Each separator ring 103 has an approximately C-shaped structure, with its outer edge extending towards and contacting the inner wall of the roller 101. Specifically, one side of each separator ring 103 has a flow guide opening, which is a notch structure reserved at a certain circumferential position in each separator ring 103. When the air inlet pipe 104 rotates to a specific angle, the flow guide opening faces downward, cooperating with the tilt angle of the roller 101, allowing the raw material in the chamber to flow from one chamber to the next by means of gravity and rolling tendency, thereby realizing the staged conveying of the raw material.

[0020] The rotating component controls the intermittent rotation of the air inlet pipe 104. When the air inlet pipe 104 maintains its initial position, the separating ring 103 isolates the raw materials in their respective chambers. The air inlet pipe 104 heats the raw materials at fixed points through each drying port 105, and the drying process continues. When the set time is reached, the rotating component drives the air inlet pipe 104 to rotate a certain angle, so that the guide opening on the separating ring 103 is in the lower position. With the help of the tilt angle of the roller 101 and the rolling force generated by the rotation, the raw materials slide into the adjacent chamber under the action of gravity. Subsequently, the air inlet pipe 104 returns to its original position, the guide opening is rotated away from the lower position, and the raw materials remain in the same position in the chamber. This structure allows the conveying behavior of the raw materials to be intermittently released and blocked by the rotation of the air inlet pipe 104, thereby realizing a cycle of drying-movement-drying.

[0021] Through this application, the raw materials are dried in batches and tumbled in stages inside the drum 101, achieving a balance between a longer residence time and a higher tumbling frequency, thus solving the problem of uneven drying caused by raw material accumulation when the traditional drum 101 is running at low speed.

[0022] In this embodiment, a plurality of discharge ports a106 are provided axially spaced on the side wall of the drum 101, and a discharge port b107 is provided on the outer shell of the drying cylinder 100 at the corresponding position, so that the raw material after drying can be discharged from the inside of the drum 101.

[0023] With the above setup, the dried material can be automatically discharged through these outlets.

[0024] In this embodiment, the driving component includes a gear structure disposed at the end of the drum 101, specifically a gear a200 coaxially mounted at one end of the drum 101. A motor a201 is disposed outside the drying drum 100, and a gear b202 is fixedly connected to the drive shaft of the motor a201, with the gear b202 meshing with the gear a200.

[0025] With the above setup, the motor a201 located outside the drying cylinder 100 is started, and the gear b202 on the drive shaft rotates accordingly and meshes with the gear a200 located at the end of the drum 101, thereby driving the drum 101 to achieve stable rotation around the central axis inside the drying cylinder 100. During the rotation of the drum 101, the raw material continuously tumbles in each partitioned chamber, achieving physical disturbance. At the same time, in conjunction with the directional blowing of hot air, a fully convective drying environment is formed.

[0026] In this embodiment, the rotating component is used to control the intermittent rotation of the intake pipe 104, and its structure includes a pair of meshing gears disposed outside the intake pipe 104. Specifically, a gear c203 is fixedly disposed on the outer circumference of the intake pipe 104, and a motor b204 is mounted on the outer wall of the drying cylinder 100. The output shaft of the motor b204 is also provided with a gear c203 that meshes with the gear c203 on the intake pipe 104.

[0027] When motor b204 is working, it drives the output shaft to rotate, which in turn drives the gear c203 on it to rotate, and then drives the intake pipe 104 to rotate slowly through the meshing transmission structure. The motor b204 and the intake pipe 104 are connected by a gear pair to realize the intermittent transmission of power and angle control.

[0028] In this embodiment, motor b204 can be connected to the control system. According to process requirements, the operator can set the start and stop time, rotation angle and running cycle of motor b204 through control modules such as pulse controller, timer relay or encoder, so as to achieve precise control of the rotation rhythm of intake pipe 104.

[0029] In this embodiment, to prevent the intake pipe 104 from rotating when not in operation, the output shaft of the motor b204 can be equipped with a self-locking structure, such as a stepper motor with a self-locking gearbox or a worm gear transmission structure. This structure can maintain the stable position of the output shaft even when the motor is braked or powered off, preventing the guide opening from deviating from the set position due to rotation or vibration, thereby ensuring the reliability of the material sealing state.

[0030] With the above setup, when the device is running, motor b204 starts at set time intervals, and its output shaft drives the gear c203 connected to it to rotate, which meshes with another gear c203 fixed on the outer periphery of the air inlet pipe 104, thereby causing the air inlet pipe 104 to rotate at an angle. When the air inlet pipe 104 rotates to the point where the guide opening faces downward, the raw material in the chamber will slide into the next adjacent chamber under the combined action of the rotation and tilt angle of the drum 101 itself, realizing the phased renewal of materials.

[0031] After rotation is complete and material flow is achieved, the inlet of the air pipe 104 moves to the lower position, thereby closing the material flow path and restoring the raw material to a dry state. By controlling the running time and interval frequency of the motor b204, the drying cycle of the raw material in each chamber can be precisely set, thus adapting to raw materials with different moisture contents or heat-sensitive properties.

[0032] In this embodiment, to enhance the tumbling and agitation effect of the material within the drum 101, a plurality of paddles 205 are provided on the inner wall of the drum 101 along the circumferential direction. Each paddle 205 is fixedly connected to the inner wall of the drum 101 and is evenly arranged along the axial direction of the drum 101. The length of the paddle 205 is slightly shorter than the distance between two adjacent separating rings 103 to ensure that it forms an effective paddle action in each chamber.

[0033] With the above configuration, during the operation of the device, the drum 101 is driven by the drive component to rotate slowly. The raw materials are separated into each chamber by the separating ring 103. As the drum 101 rotates, the material itself will roll along the drum wall. However, if the material particle size is small or the moisture content is high, relying solely on gravity to roll can easily lead to slippage or accumulation, which is not conducive to sufficient turning and uniform heating.

[0034] At this time, multiple paddles 205 mounted on the inner wall of the drum 101 rotate together with the drum 101, creating periodic mechanical agitation of the raw material within the chamber. Whenever a paddle 205 passes through a material accumulation area, it lifts and agitates the material, resulting in a more thorough scattering and tumbling effect within the chamber. This passive stirring action effectively expands the heated surface area of ​​the material, accelerates the evaporation of surface moisture, and promotes the rapid escape of internal moisture, thereby increasing the overall drying rate.

[0035] In this embodiment, to achieve structural decoupling between the hot air input and rotational motion of the air intake pipe 104, an extension pipe 206 is provided at the air intake end of the air intake pipe 104. The extension pipe 206 is rotatably sleeved on the outside of the air intake pipe 104, and the two are coaxially connected. The extension pipe 206 is used to connect to an external heat source device, thereby establishing a hot air supply path.

[0036] Specifically, staff can select hot air supply equipment according to usage needs, such as a hot air generator, hot air furnace, or electric heating blower system, and connect it to the extension pipe 206 via a flexible connecting pipe. External hot air is continuously supplied into the air inlet pipe 104 through the extension pipe 206, and then evenly sprayed into each chamber inside the drum 101 through multiple drying ports 105 on the air inlet pipe 104, thereby achieving segmented hot air drying of the raw materials.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
