Description

Technical Field

[0001] This application relates to the field of grain processing technology, and in particular to a drying mechanism for rice processing. Background Technology

[0002] In the rice production process, grain drying is a crucial step. Effective drying not only ensures the quality of the grains but also lays a solid foundation for subsequent processing steps.

[0003] Currently, most rice production enterprises use hot air drying before filtering and removing impurities from the grains. This usually involves using a hot air blower to dry the grains piled up in the warehouse. During the drying process, in order to improve the drying effect, workers need to turn the grains over from time to time to promote the penetration and distribution of hot air in the grain pile. After drying, the grains are fed by a hoist.

[0004] In practice, while this method can achieve grain drying to some extent, the results are uneven. Although manual turning has some effect, the uneven heating of the grain during the drying process is due to variations in the density of the grain pile, the distribution of the hot air blower, and the unevenness of the hot air temperature, resulting in inconsistent drying outcomes. Furthermore, manually turning the grain is not only inefficient but also consumes a significant amount of labor.

[0005] To address the aforementioned issues, a drying mechanism for rice processing is now designed. Utility Model Content

[0006] This application provides a drying mechanism for rice processing to solve the problem in related technologies where drying grains stored in a warehouse is done by using a hot air blower and manually turning the grains, resulting in uneven drying and low efficiency.

[0008] A drying chamber is provided inside the drying chamber, and a drying cylinder is rotatably mounted outside the feeding pipe. The feeding pipe is used to feed materials into the drying cylinder. A driving component is provided inside the drying chamber to drive the drying cylinder to rotate.

[0009] The drying cylinder has several discharge holes at one end for discharging material;

[0010] The drying chamber is equipped with a hot air unit, which is used to send hot air into the drying chamber to dry the material.

[0011] The hot air unit includes a housing mounted on the drying chamber, several electric heating rods disposed inside the housing, and multiple fans mounted on the housing. The housing is connected to the drying chamber. The fans are used to deliver outside air into the drying chamber, and the electric heating rods are used to heat the air.

[0012] In some embodiments, one end of the feed pipe extends to the outside of the drying chamber, and the outwardly extending end of the feed pipe is provided with a feed unit for feeding materials;

[0013] The feeding pipe has a feeding hole located inside the drying cylinder, which is used to feed the material into the drying cylinder.

[0025] The drive unit also includes two toothed annular tracks disposed opposite each other on the drying cylinder, and two gears disposed opposite each other on the rotating shaft, the gears meshing with the corresponding toothed annular tracks.

[0026] In some embodiments, the drying cylinder is provided with spiral blades inside, which are used to guide the material to be conveyed to the discharge port side.

[0027] In some embodiments, the bottom of the drying chamber is provided with a discharge port located at the bottom of the discharge hole, and the bottom of the drying chamber is also provided with a guide hopper located below the discharge port.

[0028] In some embodiments, the feed tube is provided with a plurality of short rods arranged in a ring on the outside, the short rods being used to disperse the material inside the drying cylinder, and the short rods being provided with heating wires inside.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] This application provides a drying mechanism for rice processing, which can solve the problem in related technologies where drying grains stored in a warehouse is done by using a hot air blower and manually turning the grains, resulting in uneven drying and low efficiency.

[0040] Please see Figures 1-3 A drying mechanism for rice processing includes: a drying chamber 1, a feeding pipe 2 inside the drying chamber 1, and a drying cylinder 3 rotatably mounted outside the feeding pipe 2. The feeding pipe 2 is used to feed materials into the drying cylinder 3. A driving component 4 is installed inside the drying chamber 1 to drive the drying cylinder 3 to rotate. One end of the drying cylinder 3 has several discharge holes 31 for discharging materials. A hot air unit 5 is installed on the drying chamber 1 to send hot air into the drying chamber 1 to dry the materials. The hot air unit 5 includes a housing 51 installed on the drying chamber 1, several electric heating rods 52 installed inside the housing 51, and multiple fans 53 installed on the housing 51. The housing 51 is connected to the drying chamber 1. The fans 53 are used to send external air into the drying chamber 1, and the electric heating rods 52 are used to heat the air.

[0041] First, the grain material is fed into the drying cylinder 3 located outside the feed pipe 2. Once the material enters the drying cylinder 3, the drive unit 4 starts to work, driving the drying cylinder 3 to rotate inside the drying chamber 1, which promotes the uniform distribution of the grain in the drying cylinder 3 and greatly increases the contact area between the grain and the hot air, thereby improving the drying efficiency.

[0042] At the same time, the hot air unit 5 is activated, drawing outside air into the housing 51. Inside the housing 51, several electric heating rods 52 heat the air to a suitable temperature, forming hot air. Subsequently, multiple fans 53 send this hot air into the drying chamber 1, where it undergoes thorough heat exchange with the rotating material. The hot air not only removes moisture from the material but also ensures uniform heating of the material during the drying process.

[0043] As the drying process proceeds, the material gradually dries and is eventually discharged through the discharge hole 31 at one end of the drying cylinder 3.

[0044] By using a rotating drying drum 3 and introducing hot air, the drying efficiency of the material is improved. The rotation ensures full contact between the material and the hot air, while the hot air quickly removes moisture from the material. The rotation of the drying drum 3 and the uniform air delivery of the hot air unit 5 together ensure that the material is heated evenly during the drying process, avoiding uneven drying of the grains and improving the overall quality of the product.

[0045] Due to its high and uniform drying efficiency, this drying unit can complete the drying task in a short time, thereby reducing energy consumption and production costs. Furthermore, the efficient operation of the electric heating rod 52 and the fan 53 further reduces energy consumption.

[0046] like Figure 2 and Figure 4 As shown, in this embodiment, one end of the feeding pipe 2 extends to the outside of the drying chamber 1, and the feeding unit 6 for feeding is provided at the outward-extending end of the feeding pipe 2; a feeding hole 23 located inside the drying cylinder 3 is provided on the feeding pipe 2, and the feeding hole 23 is used to feed the material into the drying cylinder 3.

[0047] The feed pipe 2 serves as the main channel for materials to enter the drying cylinder 3. One end of the feed pipe 2 extends to the outside of the drying chamber 1, allowing the material to be stored outside the drying chamber 1 and then fed into the drying cylinder 3 for drying when needed.

[0048] The feeding unit 6 is responsible for continuously or intermittently feeding materials from storage or pretreatment equipment into the feeding pipe 2.

[0049] A feeding hole 23 is provided on the part of the feeding pipe 2 located inside the drying cylinder 3. The feeding hole 23 allows the material to enter the drying cylinder 3 evenly and stably, and to fully exchange heat with the rotating drying cylinder 3 and the hot air generated by the hot air unit 5, thereby achieving rapid and uniform drying.

[0050] The cooperation between the feeding pipe 2 and the feeding unit 6 enables the material to enter the drying cylinder 3 continuously or intermittently, ensuring the continuity and stability of the drying process, improving the efficiency of material conveying, and reducing waiting time and energy consumption in the production process.

[0051] like Figure 6 As shown, in one embodiment, the feeding unit 6 includes: a screw conveyor 61 connected to one end of the feeding pipe 2 extending outward; and an external transmission pipe 62 communicating with the screw conveyor 61.

[0052] The screw conveyor 61 is directly connected to one end of the feed pipe 2 that extends outward, and is responsible for continuously and stably feeding materials from the external transmission pipe 62 into the feed pipe 2. The external transmission pipe 62 serves as a transmission channel for materials before they enter the screw conveyor 61, ensuring that materials can quickly and smoothly enter the screw conveyor 61 when needed.

[0053] External transmission pipe 62 receives materials from upstream equipment such as material storage bins and temporarily stores or transmits them to the inlet of screw conveyor 61.

[0054] The screw blades of the screw conveyor 61 rotate under the drive of the motor, continuously and stably pushing the material from the inlet end to the outlet end, i.e., the feed pipe 2. The conveying speed of the screw conveyor 61 can be controlled by adjusting the speed of the motor, which will not be elaborated here.

[0055] like Figure 2 As shown, in one embodiment, the drying cylinder 3 is a cylindrical mesh cage, and the discharge hole 31 is located at the end of the drying cylinder 3 away from the feeding hole 23; two support seats 7 are arranged opposite each other at the bottom of the drying cylinder 3, and the support seats 7 are used to support the rotation of the drying cylinder 3.

[0056] The drying cylinder 3 has a cylindrical mesh cage structure, which increases the contact area between the material and the hot air, and also promotes the penetration and distribution of hot air in the material, thereby improving the drying efficiency.

[0057] The discharge port 31 is located at the end of the drying cylinder 3 away from the feed port 23, ensuring that the material is fully dried inside the drying cylinder 3 before being discharged. The support base 7 provides stable support for the rotation of the drying cylinder 3.

[0058] After the material enters the drying cylinder 3 through the feed hole 23, it gradually loses moisture and is dried under the action of hot air. Because the drying cylinder 3 has a cylindrical mesh structure, the hot air can easily penetrate the material layer and exchange heat thoroughly with the material. The fully dried material continues to rotate inside the drying cylinder 3 and is eventually discharged through the discharge hole 31. Since the discharge hole 31 is located at the end furthest from the feed hole 23, the material has sufficient drying time inside the drying cylinder 3.

[0059] In one embodiment, the support base 7 includes: a slip ring 71 disposed on the drying cylinder 3; a base 72 disposed inside the drying chamber 1; and two rollers 73 rotatably disposed on the base 72; the two rollers 73 are located on both sides of the corresponding slip ring 71 and slide in cooperation with the corresponding slip ring 71.

[0060] The slip ring 71 is fixedly mounted on the outside of the drying cylinder 3, serving as a part that slides and engages with the roller 73. The base 72 is fixed on the inside of the drying chamber 1, providing a stable mounting base for the roller 73. The two rollers 73 are rotatably mounted on the base 72 and located on both sides of the corresponding slip ring 71, forming a sliding engagement with the slip ring 71, thereby supporting and allowing the drying cylinder 3 to rotate around its axis.

[0061] When the driving component 4 drives the drying cylinder 3 to rotate, the slip ring 71 rotates together with the drying cylinder 3. Since a sliding fit is formed between the roller 73 and the slip ring 71, the roller 73 will roll on the surface of the slip ring 71, thereby supporting the rotation of the drying cylinder 3 and reducing frictional resistance.

[0062] The sliding fit between roller 73 and slip ring 71 ensures the stability of drying cylinder 3 during rotation.

[0063] like Figure 3 As shown, in one embodiment, the driving component 4 includes multiple support plates 41 disposed above the interior of the drying chamber 1. A rotating shaft 42 is rotatably disposed between the multiple support plates 41, with one end of the rotating shaft 42 extending outward. A reducer and a drive motor are disposed on one side of the drying chamber 1. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the outwardly extending end of the rotating shaft 42. The driving component 4 also includes two toothed annular tracks 43 disposed opposite to each other on the drying cylinder 3, and two gears 44 disposed opposite to each other on the rotating shaft 42. The gears 44 mesh with the corresponding toothed annular tracks 43. The racks on the outside of the toothed annular tracks 43 are adapted to the gears.

[0064] Multiple support plates 41 provide stable support for the rotating shaft 42. One end of the rotating shaft 42 extends outward to connect with the output shaft of the reducer.

[0065] Two gears 44 mesh with corresponding toothed annular tracks 43. When the rotating shaft 42 rotates under the drive of the drive motor and reducer, the gears 44 will roll along the toothed annular tracks 43, thereby driving the drying cylinder 3 to rotate around its axis.

[0066] When it is necessary to drive the drying cylinder 3 to rotate, the drive motor is started, the output shaft of the drive motor starts to rotate, and after being reduced in speed by the reducer, it is transmitted to the rotating shaft 42. The rotating shaft 42 starts to rotate under the drive of the drive motor and the reducer. Since the gear 44 on the rotating shaft 42 meshes with the toothed annular track 43 on the drying cylinder 3, the gear 44 will roll along the toothed annular track 43. As the gear 44 rolls on the toothed annular track 43, the drying cylinder 3 is driven to rotate around its axis.

[0067] like Figure 4 and Figure 5 As shown, the drying cylinder 3 is further provided with a spiral blade 8 inside, which is used to guide the material to be conveyed to the discharge hole 31 side.

[0068] A spiral blade 8 is added inside the drying cylinder 3. The spiral blade 8 is arranged spirally along the axis of the drying cylinder 3. Its function is to guide the material inside the drying cylinder 3 to be conveyed to the discharge hole 31.

[0069] The spiral shape of the spiral blades 8 enables them to effectively guide the material along a specific path inside the drying cylinder 3. When the drying cylinder 3 rotates, the spiral blades 8 rotate with the material and use the thrust generated by their spiral shape to push the material toward the discharge port 31. As the drying cylinder 3 continues to rotate, the spiral blades 8 continuously propel the material forward.

[0070] When the material is conveyed to the vicinity of the discharge hole 31, it will be smoothly discharged from the discharge hole 31 due to the guiding effect of the spiral blades 8, ensuring the continuous conveying and discharge of the material inside the drying cylinder 3, and avoiding the problems of material accumulation and uneven drying.

[0071] It should be noted that the bottom of the drying chamber 1 is provided with a discharge port 11 located at the bottom of the discharge hole 31, and the bottom of the drying chamber 1 is also provided with a guide hopper 12 located below the discharge port 11.

[0072] The discharge port 11 is located directly below the discharge hole 31, ensuring that the material discharged from the drying cylinder 3 can fall directly into the discharge port 11 and smoothly enter the next processing stage.

[0073] To further improve the efficiency and convenience of material collection, a guide hopper 12 is added below the discharge port 11. The guide hopper 12 is box-shaped with an open top and one side. The side of the guide hopper 12 with the opening is tilted downward, which is conducive to the smooth sliding of materials and can also prevent materials from splashing or scattering during the sliding process to a certain extent.

[0074] Once the grains in the drying drum 3 have been dried to the preset dryness level, they are discharged from the discharge hole 31 and fall directly into the discharge port 11 located below it. The grains falling into the discharge port 11 immediately enter the guide hopper 12, and under the guidance of the guide hopper 12, the material will eventually be concentrated at its outlet. In this way, the operator can easily collect the material for subsequent processing.

[0075] By combining the discharge port 11 and the guide hopper 12, materials can be collected more efficiently, preventing them from scattering during the discharge process. At the same time, it simplifies the operator's workflow, making material collection and subsequent processing easier.

[0076] In a preferred embodiment, the feed pipe 2 is provided with a plurality of short rods 21 arranged in a ring on the outside. The short rods 21 are used to disperse the material inside the drying cylinder 3. The short rods 21 are provided with heating wires 22 inside.

[0077] The short rod 21 serves to disperse the material inside the drying cylinder 3, and also provides preheating for the material through the heating wire 22 installed inside it.

[0078] The number and distribution of the short rods 21 can be adjusted according to actual needs to ensure that they can effectively cover the outside of the feed pipe 2 and fully disperse and preheat the material before it enters the drying cylinder 3. The length and diameter of the short rods 21 also need to be rationally designed according to the characteristics of the material and the size of the drying cylinder 3 to avoid obstructing the material conveying and the spiral blades 8.

[0079] When the material enters the drying cylinder 3 through the feed pipe 2, the short rod 21 effectively disperses it. This helps prevent the material from accumulating or clumping inside the drying cylinder 3, thereby improving the uniformity and efficiency of drying.

[0080] The heat generated inside the short rod 21 by the heating wire 22 is transferred to the material, causing it to reach a certain temperature before entering the drying cylinder 3. The preheated material is more likely to absorb the heat inside the drying cylinder 3, thereby accelerating the drying process.

[0081] By dispersing and preheating the material, the drying efficiency inside the drying drum 3 is significantly improved. This not only shortens the drying time but also reduces energy consumption and production costs.

[0082] In this embodiment, the electric heating rod 52 and the electric heating wire 22 are key heating elements in the drying equipment. Generally speaking, the temperature range of the electric heating wire drying device is relatively wide, and the hot air temperature can be controlled between 50℃ and 160℃.

[0083] However, for certain materials such as rice, in order to maintain its quality and prevent overheating damage, the drying temperature is usually set in a lower range. The drying temperature of the electric heating rod 52 and the electric heating wire 22 is set at about 36-42℃ to ensure that the dehydration rate is controlled within 0.7% of the rice moisture content per hour, thereby better ensuring the quality of the dried rice.

[0084] In another embodiment, the drying chamber 1 in this embodiment is provided with ventilation holes.

[0085] The main function of the ventilation holes is to facilitate the exhaust and renewal of gas inside the drying chamber 1. By venting the gas inside the drying chamber 1, the airflow rate of the gas inside the drying chamber 1 is increased.
