Description
Technical Field
[0001] This utility model relates to the field of grain production technology, and more specifically, to a rapid drying device for rice production. Background Technology
[0002] During the grain production process, after harvesting, a large amount of grain will become moldy and sprout because it is not dried in time during threshing, drying, storage, transportation, processing, and consumption. Therefore, it is necessary to dry the grain in time after harvesting.
[0003] Existing drying equipment results in the accumulation and sticking of damp rice grains during transportation and drying. Hot air cannot penetrate the accumulated rice grains to dry the internal moisture, leading to low drying efficiency. Furthermore, the equipment only has a single drying chamber. If high-temperature drying is used in a single drying chamber, it can easily cause the rice grains to form a crust. If the drying temperature is too low, it may be impossible to dry the moisture. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a rapid drying equipment for rice production that improves drying efficiency and product quality by dividing the rice into multiple drying zones and using different drying coefficients at different stages.
[0005] To solve the above problems, the present invention adopts the following technical solution.
[0006] A rapid drying device for rice production includes: Frame; A drying mechanism includes a drying chamber and a drying assembly; the drying chamber is mounted on the frame and has three separate drying zones inside: a high-temperature drying zone, a static drying zone, and a low-temperature slow drying zone; the drying assembly has heating elements located within the high-temperature drying zone and the low-temperature slow drying zone, situated on the inner wall of the drying chamber, for drying rice; and The vibrating conveying mechanism includes a conveying plate and a vibrator; the conveying plate is inclinedly arranged at the bottom of the drying box along the discharge direction and continuously passes through the high-temperature drying zone, the static drying zone and the low-temperature slow drying zone, and is used to place rice grains; the vibrator is arranged at the bottom of the conveying plate and is used to vibrate the rice grains on the conveying plate.
[0007] The technical solutions described in this application example have at least the following technical effects: This drying equipment divides the drying chamber into three drying zones: a high-temperature drying zone, a static drying zone, and a low-temperature slow drying zone. In the high-temperature drying zone, a large amount of moisture on the surface of the grain pile is quickly removed by high temperature. In the static drying zone, moisture inside the grain pile migrates to the outside, ensuring a balance of moisture inside and outside the grain pile. Finally, the low-temperature slow drying slowly evaporates the moisture in the grain pile, preventing the rice from spoiling due to excessive evaporation. As can be seen, this equipment improves drying efficiency by matching different process parameters at different drying stages to meet the process requirements of rice at different stages. At the same time, the vibrating conveyor mechanism vibrates the rice, causing it to bounce up and down repeatedly during transportation, preventing the wet rice from sticking together. Hot air can be transmitted into the inside of the grain pile to dry the rice inside, further improving drying efficiency and product quality.
[0008] In some embodiments, the rapid drying equipment for rice further includes an infeed / outfeed mechanism disposed on the side of the drying chamber near the input end of the vibrating conveyor mechanism for feeding rice into and out of the drying chamber.
[0009] In some embodiments, the drying chamber is provided with a feed inlet near the high-temperature drying zone and a discharge outlet near the low-temperature slow drying zone on both sides; the feeding and discharging mechanism includes: A feeding assembly, located at the feeding inlet, is used to transport rice into the drying chamber; A discharge pipe is installed at the discharge port to discharge the dried rice.
[0010] In some embodiments, a heat-insulating curtain is provided between the high-temperature drying zone, the static drying zone, and the low-temperature slow drying zone to prevent heat transfer.
[0011] In some embodiments, the drying assembly further includes a blower disposed in the high-temperature drying zone and the static drying zone and located on the inner wall of the drying chamber for drying rice; and a thermal sensor disposed in the high-temperature drying zone, the static drying zone and the low-temperature slow drying zone and located on the inner wall of the drying chamber for measuring temperature.
[0012] In some embodiments, the conveyor plate is divided into a first conveyor plate, a second conveyor plate, and a third conveyor plate, which are respectively arranged in the high-temperature drying zone, the static drying zone, and the low-temperature slow drying zone; the vibration frequency of the first conveyor plate is greater than that of the second conveyor plate; the vibration frequency of the second conveyor plate is greater than that of the third conveyor plate.
[0013] In some embodiments, a soft rubber connecting block for eliminating gaps is provided between the first conveyor plate, the second conveyor plate and the third conveyor plate.
[0014] In some embodiments, three vibrators are provided; the three vibrators are respectively arranged under the first conveyor plate, the second conveyor plate and the third conveyor plate.
[0015] In some embodiments, the vibrating conveying mechanism further includes a spring disposed between the conveying plate and the bottom of the drying chamber to prevent the drying chamber from shaking. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 and Figure 2This utility model provides a rapid drying device for rice production, comprising: a frame 10; a drying mechanism 20, including a drying chamber 21 and a drying assembly 22; the drying chamber 21 is mounted on the frame 10 and has three separate drying zones inside, namely a high-temperature drying zone 211, a static drying zone 212, and a low-temperature slow drying zone 213; the drying assembly 22 has a heating element 221 disposed in the high-temperature drying zone 211 and the low-temperature slow drying zone 213 and located on the inner side wall of the drying chamber, for drying rice; and a vibrating conveying mechanism 3030, including a conveying plate 31 and a vibrator 32; the conveying plate 31 is inclinedly disposed at the bottom of the drying chamber 21 and passes through the high-temperature drying zone 211, the static drying zone 212, and the low-temperature slow drying zone 213, for holding rice; the vibrator 32 is disposed at the bottom of the conveying plate 31 for vibrating the rice on the conveying plate 31.
[0020] Understandably, the frame 10 is a component that supports and installs the drying equipment. For example, it can be a frame-type frame 10 or a box-type mounting frame 10, but it is not limited to these. The drying chamber 21 is a component that removes moisture from the damp rice inside. For example, it can be a heated drying chamber 21 or a wind-blown drying chamber 21, but it is not limited to these. The internal area of the drying chamber 21 is divided into three drying zones. The order in which the three drying zones are set affects the drying effect on the rice. For example, it can be divided into a high-temperature drying zone 211, a static drying zone 212, and a low-temperature slow drying zone 213. In the high-temperature drying zone 211, high-temperature baking quickly dries the moisture in the rice pile. In the static drying zone 212, the rice is left to stand, allowing internal moisture to penetrate to the surface of the rice pile. In the low-temperature slow drying zone 213, the rice evaporates moisture at a low temperature. Alternatively, the rice can be first sent to the low-temperature slow drying zone 213, then to the static drying zone 212, and finally to the high-temperature drying zone 211 for rapid moisture evaporation, etc., but it is not limited to these specific arrangements. The conveyor plate 31 is a platform component that carries rice grains. For example, it can be a plate-shaped conveyor plate 31 or a trough-shaped carrying platform, but it is not limited to these. The vibrator 32 is a component that drives the conveyor plate 31 to vibrate, thereby causing the rice grains on the conveyor plate 31 to bounce forward. For example, it can be a vibrating motor or a vibrator, but it is not limited to these.
[0021] As described above, the drying equipment divides the drying chamber 21 into three drying zones: a high-temperature drying zone 211, a static drying zone 212, and a low-temperature slow drying zone 213. In the high-temperature drying zone 211, a large amount of moisture on the surface of the grain pile is quickly removed by high temperature. In the static drying zone 212, moisture inside the grain pile migrates to the outside, ensuring a balance of moisture inside and outside the grain pile. Then, the moisture in the grain pile is slowly evaporated by low-temperature slow drying, preventing the rice from spoiling due to excessively rapid evaporation. Therefore, this equipment improves drying efficiency and product quality by matching different process parameters at different drying stages to meet the process requirements of rice at different stages. The equipment is also equipped with a vibrating conveyor mechanism 30, which causes the rice to bounce repeatedly during transportation, allowing heat to penetrate the surface of the grain pile and fully dry the rice inside, further improving drying efficiency.
[0022] Optionally, in some embodiments, please refer to Figure 3 The rapid drying equipment for rice also includes a feeding and discharging mechanism 40 located on the side of the drying chamber 21 near the input end of the vibrating conveyor mechanism 3030, for feeding rice into and discharging rice into the drying chamber 21.
[0023] Understandably, the feeding and discharging mechanism 40 is a component for feeding rice into and out of the drying box 21. For example, it can be a suction-type feeding and discharging mechanism 40, or a conveyor belt type conveying mechanism, etc., but is not limited to these.
[0024] Optionally, in some embodiments, please refer to Figure 2 The drying chamber 21 has an inlet 214 near the high-temperature drying zone 211 and an outlet 215 near the low-temperature slow drying zone 213 on both sides; the feeding and discharging mechanism 40 includes: a feeding component 41, which is set on the inlet 214 for transporting rice into the drying chamber 21; and a discharge pipe 42, which is set on the discharge outlet 215 for discharging the dried rice.
[0025] Understandably, the feeding assembly 41 is a component that puts the damp rice into the drying chamber 21. For example, it can be a feeding pipe 42 connected to the feeding port 214, where the rice is manually poured into the feeding pipe 42 and introduced into the drying chamber 21. Alternatively, it can be a feeding pipe 42 connected to the feeding port 214, with the feeding pipe 42 connected to a pressure pump, which automatically sucks in the rice, or other feeding methods, but it is not limited to these.
[0026] Optionally, in some embodiments, please refer to Figure 4 A heat insulation curtain 216 is provided between the high-temperature drying zone 211, the static drying zone 212 and the low-temperature slow drying zone 213 to prevent heat transfer.
[0027] Understandably, the heat insulation curtain 216 has the function of preventing heat transfer. At the same time, when the rice is transported by the vibrating conveyor 30, the rice can push the heat insulation curtain 216 open and pass through the heat insulation curtain 216 by its own weight. Therefore, the heat insulation curtain 216 can be a canvas heat insulation soft curtain, or a PVC heat insulation soft curtain, etc., but is not limited to these.
[0028] This setup, with its simple heat insulation curtain 216, not only prevents heat loss between the three drying zones but also allows the rice to flow freely within each drying zone, simplifying the structure of the drying equipment and reducing costs.
[0029] Optionally, in some embodiments, please refer to Figure 2 The drying assembly 22 also includes a blower 222 disposed in the high-temperature drying zone 211 and the static drying zone 212, and located on the inner wall of the drying chamber 21, for drying rice. It also includes a thermal sensor 223 disposed in the high-temperature drying zone 211, the static drying zone 212, and the low-temperature slow drying zone 213, and located on the inner wall of the drying chamber 21, for measuring temperature.
[0030] Understandably, in the high-temperature drying zone 211 and the static drying zone 212, the blower 222 is a component that dries the moisture of the rice by blowing air. For example, it can be an electric blower or a pneumatic blower, but it is not limited to these.
[0031] This configuration allows for faster airflow within the high-temperature drying zone 211 via the blower 222, enabling the heat generated by the heating element 221 to be distributed more quickly throughout the drying zone, thus improving drying efficiency. Within the stationary drying zone 212, the airflow generated by the blower 222 can more quickly disperse surface moisture, further enhancing drying efficiency.
[0032] Optionally, in some embodiments, please refer to Figure 2 The conveyor plates 31 are divided into a first conveyor plate 311, a second conveyor plate 312, and a third conveyor plate 313, which are correspondingly arranged in the high-temperature drying zone 211, the static drying zone 212, and the low-temperature slow drying zone 213. The vibration frequency of the first conveyor plate 311 is higher than that of the second conveyor plate 312. The vibration frequency of the second conveyor plate 312 is higher than that of the third conveyor plate 313. Soft rubber connecting blocks 314 are provided between the first conveyor plate 311, the second conveyor plate 312, and the third conveyor plate 313 to eliminate gaps. Three vibrators 32 are provided. The three vibrators 32 are correspondingly arranged under the first conveyor plate 311, the second conveyor plate 312, and the third conveyor plate 313.
[0033] Understandably, since the drying requirements of rice differ in the high-temperature drying zone 211, the static drying zone 212, and the low-temperature slow drying zone 213 during the drying process, the residence time in these three zones varies. This difference can be achieved through different structural settings. For example, the conveyor plate 31 can be divided into a first conveyor plate 311, a second conveyor plate 312, and a third conveyor plate 313, and these can be arranged in the three drying zones respectively. Simultaneously, a vibrator 32 can be installed under each of the first, second, and third conveyor plates 311 and 313, or there can be one conveyor plate 31 and one vibrator 32. However, the lengths of the high-temperature drying zone 211, the static drying zone 212, and the low-temperature slow drying zone 213 can differ. For instance, the low-temperature slow drying zone 213 could have the longest length, while the high-temperature drying zone 211 could have the shortest. These settings, however, can achieve differences in the residence time of rice in different zones, but are not limited to these methods. Because the first method allows for more flexible control of the rice transport speed by adjusting the vibration frequency of the vibrator 32, it can adapt to more diverse drying needs. The soft rubber connecting block 314 is a component that eliminates the gap between conveyor plates by flexibly connecting the conveyor plates. For example, it can be a flange-type rubber soft connector or a sleeve-type silicone sleeve, but it is not limited to these.
[0034] This configuration divides the conveyor plate 31 into a first conveyor plate 311, a second conveyor plate 312, and a third conveyor plate 313. The first conveyor plate 311, the second conveyor plate 312, and the third conveyor plate 313 are respectively installed in the high-temperature drying zone 211, the static drying zone 212, and the low-temperature slow drying zone 213. Each of the first conveyor plate 311, the second conveyor plate 312, and the third conveyor plate 313 is equipped with a corresponding vibrator 32. The vibrator 32 can control the conveying speed of the corresponding conveyor plate, thereby enabling individual control of the residence time of rice in different zones. This configuration is suitable for various drying needs and makes processing more flexible.
[0035] As can be seen from the above, wet rice is sucked into the drying chamber 21 through the feeding component 41, the drying mechanism 20 is turned on, and at the same time the vibrating conveyor 30 makes the rice bounce forward. The heating element 221 and the blowing element 222 in the high-temperature drying chamber quickly dry the surface temperature of the wet rice. When most of the moisture is dried, the vibrating conveyor 30 transports the rice to the static drying area 212. After the moisture inside the rice pile is balanced, the rice is transported to the low-temperature slow drying area 213 for low-temperature drying. Finally, the rice is sent out of the drying chamber 21.
[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
