Technical Field
[0001] This utility model relates to the field of rice processing technology, specifically to a rice processing dehydration and drying device. Background Technology
[0002] Rice is an important food crop, with more than half of the world's population relying on it as their staple food. It is highly nutritious, rich in carbohydrates, protein, fat, vitamins, and minerals. Rice has relatively demanding growing conditions, requiring ample sunlight, water, and suitable temperatures. It is typically grown in paddy fields, with a growth cycle generally lasting 3-4 months. Rice can be used to make various foods, such as cooked rice, rice porridge, rice noodles, and rice cakes, and is widely enjoyed.
[0003] The processing of rice includes harvesting, threshing, drying, and milling. Drying is a crucial step, removing moisture from the rice to improve its quality and shelf life. Rice dehydration and drying refers to removing moisture from the rice to achieve a certain degree of dryness for storage and transportation. There are many methods for rice dehydration and drying, including natural sun-drying, mechanical drying, and solar drying. In actual production, the appropriate dehydration and drying method is usually selected based on factors such as the rice variety, moisture content, and storage time.
[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Existing drying devices often only use one drying method to dehydrate rice, and the dehydration effect is not thorough enough and the work efficiency is low; 2. Water droplets generated by existing drying devices during the dehydration process are easy to splash everywhere and are not easy to collect and clean, thus increasing the labor intensity of operators. Utility Model Content
[0005] The purpose of this utility model is to provide a rice processing dehydration and drying device to solve the problems mentioned in the background art, which are that existing drying devices often only use one drying method to dehydrate rice, resulting in insufficient dehydration, low work efficiency, and water droplets generated during the dehydration process that easily splash everywhere and are difficult to collect and clean, thus increasing the labor intensity of operators. To achieve the above objective, this utility model provides the following technical solution: a rice processing dehydration and drying device, including an outer box, a rotating shaft rotatably connected to one inner wall of the outer box, a dehydration cylinder welded to one end of the rotating shaft, an air conveying pipe inserted into the other end of the dehydration cylinder, a hot air box inserted into the other end of the air conveying pipe, a water collection trough slidably connected to the inner wall of the outer box directly below the dehydration cylinder, a material collection hopper at the top of the outer box, a discharge channel at the bottom of the material collection hopper, and a drive motor inserted into the other end of the rotating shaft.
[0006] More preferably, a sliding door is slidably connected to the top opening of the outer casing.
[0007] More preferably, the outer wall of the dehydration cylinder has several through holes, and a cylinder door is hinged to one side of the outer wall of the dehydration cylinder.
[0008] More preferably, the rotating shaft, drive motor, and dewatering cylinder together constitute the dewatering mechanism.
[0009] More preferably, an isolation net is fitted to the side of the air duct near the dehydration cylinder, and the other end of the air duct away from the dehydration cylinder is rotatably connected to the inner wall of the outer casing.
[0010] More preferably, the hot air box includes a box body, an electric heating tube, and a fan. One end of an air supply pipe is inserted into one side of the box body, the electric heating tube is fitted into the inner walls of both sides of the box body, and the fan is snapped into the inner wall of the side of the box body away from the air supply pipe.
[0011] More preferably, the top opening of the water collection tank is provided with several through slots.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In this invention, the centrifugal force generated by the high-speed rotation of the dehydration drum driven by the drive motor can quickly remove moisture from the surface of the rice, improving dehydration efficiency. During rotation, the rice is subjected to uniform centrifugal force, which ensures that the moisture is evenly distributed to the through holes and discharged, improving dehydration quality. The speed of the drive motor can be adjusted according to different rice varieties and moisture contents to achieve the best dehydration effect. The electric heating element and fan can quickly blow heated air into the air conveyor pipe and continue to push the hot air into the dehydration drum. The rapidly circulating hot air quickly removes the moisture from the rice, improving drying efficiency. The operator can control the temperature and air volume of the hot air by adjusting the power of the electric heating element and the speed of the fan to adapt to different rice varieties, moisture contents, and drying requirements to achieve the best drying effect.
[0014] In this invention, the water collection trough can collect water droplets thrown off the surface of rice, preventing water droplets from splashing everywhere. The through-channel design allows water droplets to flow smoothly into the water collection trough and be temporarily stored, thus preventing water from accumulating at the top of the water collection trough and overflowing. At the same time, when it is necessary to clean the water in the water collection trough, the water collection trough can be easily slid out for convenient centralized treatment and improved cleaning efficiency.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a rice processing dehydration and drying device, including an outer box 1, a rotating shaft 2 rotatably connected to one inner wall of the outer box 1, a dehydration cylinder 3 welded to one end of the rotating shaft 2, an air supply pipe 4 inserted into the other end of the dehydration cylinder 3, a hot air box 5 inserted into the other end of the air supply pipe 4, a water collection trough 6 slidably connected to the inner wall of the outer box 1 directly below the dehydration cylinder 3, a material collection hopper 7 provided at the top of the outer box 1, a material discharge channel 8 provided at the bottom of the material collection hopper 7, and a drive motor 9 inserted into the other end of the rotating shaft 2.
[0023] In this embodiment, as Figure 1 and Figure 5As shown, a sliding door 101 is slidably connected to the top opening of the outer box 1. It should be noted that the operator can first manually pull the sliding door 101 to slide it laterally to one side until the top opening of the outer box 1 is fully opened. Then, the cylinder door 302 of the dehydration cylinder 3 is opened, and the undried rice is poured into the inner wall of the dehydration cylinder 3. Then, the cylinder door 302 is closed, and the sliding door 101 is slid back to the top opening of the outer box 1, thus sealing the entire outer box 1 for subsequent dehydration and drying operations. In actual use, operators can easily open and close the top opening of the outer box 1 by manually pulling the sliding door 101, making it more convenient to add rice. During the dehydration and drying process, closing the sliding door 101 can effectively prevent external moisture from entering the outer box 1, maintaining a dry internal environment, which is conducive to improving the dehydration and drying effect. At the same time, the sealing design between the sliding door 101 and the outer box 1 can also ensure the airtightness of the outer box 1, prevent heat and moisture leakage, and improve energy utilization efficiency.
[0024] In this embodiment, as Figure 1 and Figure 3 As shown, the outer wall of the dehydration cylinder 3 has several through holes 301, and a cylinder door 302 is hinged to one side of the outer wall of the dehydration cylinder 3. It should be noted that after the operator pushes open the sliding door 101, the operator can first rotate the entire dehydration cylinder 3 by driving the motor 9 so that the cylinder door 302 can rotate to face the top opening of the outer box 1. At the same time, the operator opens the cylinder door 302 and pours the undried rice into the dehydration cylinder 3. Then, the operator closes the cylinder door 302 and starts the drive motor 9 to drive the dehydration cylinder 3 to rotate. During this process, the water on the surface of the rice will be thrown against the cylinder wall and discharged through the through holes 301. The rice is discharged into the outer box 1 to complete the dehydration process. In actual use, during the rotation of the dehydration cylinder 3, the water on the surface of the rice is subjected to centrifugal force and thrown towards the cylinder wall. The presence of the through hole 301 allows this water to quickly pass through the cylinder wall and be discharged, preventing water from accumulating inside the cylinder and improving the dehydration efficiency. The design of the cylinder door 302 allows the operator to easily open and close it, making it convenient to load and unload the rice into and out of the dehydration cylinder 3. Furthermore, closing the cylinder door 302 ensures that the rice will not leak during the dehydration process, thereby preventing the rice from entering other components and affecting their normal operation.
[0025] In this embodiment, as Figure 2 and Figure 3As shown, the rotating shaft 2, drive motor 9, and dewatering cylinder 3 together constitute the dewatering mechanism. It should be noted that after the operator pours the rice into the dewatering cylinder 3, the drive motor 9 can be started, causing its output end to rotate and drive the rotating shaft 2, which is connected to it, to rotate together. Simultaneously, the dewatering cylinder 3, welded to the other end of the rotating shaft 2, will also rotate synchronously, causing the entire dewatering cylinder 3 to generate centrifugal force under high-speed rotation, throwing off the water from the surface of the rice. The thrown-off water droplets will then pass through the through-hole 301 and be discharged into the outer casing 1, completing the dewatering process. During use, the centrifugal force generated by the high-speed rotation of the dehydration cylinder 3 driven by the drive motor 9 can quickly remove the water from the surface of the rice, improving the dehydration efficiency. During the rotation, the rice is subjected to uniform centrifugal force, which makes the water evenly distributed to the through holes 301 and discharged, improving the dehydration quality. At the same time, the drive motor 9 provides power, realizing the automation of the dehydration process, reducing the workload and labor intensity of manual operation. Furthermore, the speed of the drive motor 9 can be adjusted according to different rice varieties and moisture content to achieve the best dehydration effect.
[0026] In this embodiment, as Figure 3 and Figure 4 As shown, an isolation net 401 is fitted into the side port of the air conveying pipe 4 near the dehydration cylinder 3, and the other end of the air conveying pipe 4 away from the dehydration cylinder 3 is rotatably connected to the inner wall of the outer casing 1. It should be noted that while the operator starts the drive motor 9 and drives the entire dehydration cylinder 3 to rotate via the rotating shaft 2, the isolation net 401 fitted into the port of the air conveying pipe 4 can prevent rice from entering its interior. After the centrifugal dehydration of the rice is completed, the operator can start the hot air box 5, which blows hot air into the air conveying pipe 4, and the hot air will then be blown into the interior of the dehydration cylinder 3 along the air conveying pipe 4. At the same time, the drive motor 9 is started again. The dehydration cylinder 3 rotates, allowing the rice inside to be dried with hot air. In actual use, the main function of the air conveying pipe 4 is to transport hot air from the hot air box 5 to the inside of the dehydration cylinder 3, providing heat for the rice drying. Through the cooperation between the air conveying pipe 4 and the rotating dehydration cylinder 3, the hot air can be evenly distributed inside the dehydration cylinder 3, ensuring that all parts of the rice are fully dried. The isolation net 401 prevents rice from entering the air conveying pipe 4 during the centrifugal dehydration process, avoiding blockage and damage to the equipment. At the same time, the isolation net 401 can also prevent impurities and foreign objects from entering the air conveying pipe 4, ensuring the smooth flow of air and improving the efficiency of hot air transmission.
[0027] In this embodiment, as Figure 4As shown, the hot air box 5 includes a box body 501, an electric heating element 502, and a fan 503. One end of an air supply pipe 4 is inserted into one side of the box body 501. The electric heating element 502 is fitted into the inner walls of both sides of the box body 501. The fan 503 is snapped onto the inner wall of the box body 501 on the side away from the air supply pipe 4. It should be noted that after the operator completes the centrifugal dehydration of the rice, the electric heating element 502 and the fan 503 can be started simultaneously. At this time, the electric heating element 502 begins to heat the air inside the box body 501, while the fan 503, through its rotating blades, drives the hot air inside the box body 501 towards the air supply pipe 4. During this process, under the blowing of the fan 503, the hot air smoothly enters the dehydration cylinder 3 through the air supply pipe 4. Meanwhile, the drive motor 9 is started to rotate the dehydration cylinder 3, so that the rice inside the dehydration cylinder 3 can be dried with hot air. In actual use, the electric heating tube 502 can convert electrical energy into heat energy, thereby quickly heating the air inside the chamber 501, while the fan 503 can quickly blow the hot air into the air conveying pipe 4 and continue to push the hot air into the dehydration cylinder 3 through the air conveying pipe 4. Thus, the moisture in the rice is quickly removed by the rapidly circulating hot air, improving the drying efficiency. Moreover, the operator can control the temperature and air volume of the hot air by adjusting the power of the electric heating tube 502 and the speed of the fan 503, so as to flexibly adjust the drying conditions according to different rice varieties, moisture content and drying requirements to obtain the best drying effect.
[0028] In this embodiment, as Figure 5 As shown, the top opening of the water collection trough 6 has several through slots 601. It should be noted that when the operator starts the drive motor 9 and drives the entire dewatering cylinder 3 to rotate via the rotating shaft 2, the water originally attached to the surface of the rice will be thrown off by centrifugal force. The thrown-off water droplets will pass through the through holes 301 and be discharged into the outer casing 1, adhering to its inner wall. Then, under the action of gravity, the water droplets will converge and flow downwards to the water collection trough 6, and fall into the interior of the water collection trough 6 through the through slots 601 at its top. After the rice dehydration and drying process is completed, the operator can manually slide out the water collection trough 6 filled with water for easy centralized cleaning. In actual use, the water collection trough 6 can collect water droplets thrown off the surface of the rice, preventing water droplets from splashing everywhere. The through groove 601 allows water droplets to flow smoothly into the water collection trough 6 and be temporarily stored, thus preventing water from accumulating at the top of the water collection trough 6 and overflowing. At the same time, when it is necessary to clean the water in the water collection trough 6, the water collection trough 6 can be easily slid out for convenient centralized processing and improved cleaning efficiency.
[0029] The method of use and advantages of this utility model: The working process of this rice processing dehydration and drying device is as follows:
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the operator can first manually pull the sliding door 101 to slide it laterally to one side until the top opening of the outer box 1 is fully opened. Then, the drive motor 9 rotates the entire dewatering cylinder 3 so that the cylinder door 302 can rotate to face the top opening of the outer box 1. At the same time, the cylinder door 302 is opened again and the undried rice is poured into the dewatering cylinder 3. Then, the cylinder door 302 is closed and the sliding door 101 is slid back to the top opening of the outer box 1, thereby sealing the entire outer box 1. At the same time, the drive motor is started. Motor 9 starts rotating at its output end, causing the shaft 2 connected to it to rotate as well. Simultaneously, the dewatering cylinder 3 welded to the other end of shaft 2 rotates synchronously, generating centrifugal force under high-speed rotation. This force throws water off the surface of the rice, and the thrown-off water droplets pass through the through-hole 301 and are discharged into the outer casing 1. The water droplets adhere to the inner wall of the outer casing 1 and then, under gravity, converge and flow downwards into the water collection tank 6. The water is drawn through a slot 601 at the top and falls into the water collection tank 6. After the operator completes the centrifugal dehydration of the rice, the electric heating element 502 and the fan 503 can be started simultaneously. At this time, the electric heating element 502 starts to heat the air inside the chamber 501, while the fan 503 drives the hot air inside the chamber 501 to blow towards the air conveyor 4 through its rotating blades. During this process, the hot air blown by the fan 503 will smoothly enter the dehydration cylinder 3 through the air conveyor 4. At the same time, the drive is started. The motor 9 drives the dewatering cylinder 3 to rotate, so that the rice inside the dewatering cylinder 3 can be dried with hot air. After drying, the operator can rotate the cylinder door 302 of the dewatering cylinder 3 to the top opening of the outer box 1 by driving the motor 9 again, and open the sliding door 101 and the cylinder door 302 in sequence. At the same time, the water collection trough 6 is slid out. Then, the dewatering cylinder 3 is rotated so that the cylinder door 302 faces downward, so that the rice inside can fall from the center outward into the collection hopper 7, and enter the discharge channel 8 through the collection hopper 7, and then be discharged.
