Description

Technical Field

[0001] This utility model belongs to the field of rice processing technology, specifically relating to a rice moistening and processing equipment. Background Technology

[0002] In rice processing, brown rice, obtained after hulling, needs to undergo milling to remove the outer bran layer before it can be processed into edible white rice. However, the bran layer of brown rice (including the pericarp, seed coat, and aleurone layer) has a dense and hard structure. Direct mechanical milling can easily lead to grain breakage and uneven milling, reducing the rice yield and affecting the integrity and taste of the finished rice. Traditional processing methods, lacking effective pretreatment, have long suffered from high broken rice rates, high milling energy consumption, and cracks on the rice grain surface, hindering the quality and efficiency of rice processing. To optimize milling, the "moistening brown rice" technique has emerged. This technique involves adjusting the moisture content of the brown rice, using the osmotic effect of water to soften the bran layer and reduce its bond strength with the endosperm, thus making the subsequent milling process more efficient and gentle.

[0003] For example, Chinese Patent Publication No. CN212855866U discloses a rice moistening device, belonging to the field of rice processing technology. It includes a main frame with an inclined moistening pipe inside. The higher end of the moistening pipe is the inlet, and the opposite end is the outlet. The inlet is connected to a feed pipe. Inside the main frame, a nozzle support is also provided, with an atomizing nozzle connected to it. A support is also located inside the moistening pipe, and a driving device is also located inside the main frame, connected to the support. A supporting slip ring is located outside the moistening pipe, and a groove is provided in the main frame to facilitate the sliding of the supporting slip ring. A notch is opened at the upper end of the moistening pipe, facing the atomizing nozzle. This rice moistening device has a simple structure and good moistening effect.

[0004] The above application still has shortcomings. Due to the obstruction of the humidification pipe and the low movement of the rice, the humid air containing water droplets cannot fully and evenly contact the rice, resulting in an insufficient humidification effect and affecting the overall humidification effect of the rice.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a rice processing and conditioning equipment to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rice processing and humidifying device includes a processing tank with open top and bottom. Multiple staggered guide plates are fixed to the two opposite inner sidewalls of the processing tank. The guide plates are arranged at an angle, with a gap between one end of each guide plate and the inner sidewall of the processing tank. The gaps between adjacent guide plates and the inner sidewall of the processing tank are staggered. A first humidifying component for blowing air onto the rice is installed inside the processing tank, and a second humidifying component for humidifying the rice is installed on the side of the processing tank.

[0009] Preferably, the first humidification component includes a second cavity formed in the side wall of the processing tank, and the second humidification component includes a blower plate embedded in the side wall of the processing tank. The blower plate is provided in multiple ways and the multiple blower plates are spaced apart between the multiple guide plates. The blower plate has a second cavity inside it. The blower plate has a second air hole on its side facing the center of the processing tank that communicates with the second cavity. The second air hole is provided in multiple ways and the multiple second air holes are equidistantly distributed.

[0010] Preferably, a convex tube is fixed on the blower plate, and the convex tube extends into the second cavity and is connected to the second cavity.

[0011] Preferably, each of the multiple guide plates has a first cavity communicating with the second cavity, and the top surface of the guide plate has a first air blowing hole communicating with the first cavity. An air supply pipe communicating with the second cavity is fixed on the outer wall of the processing tank.

[0013] Preferably, two symmetrically distributed support rods are fixed on the outer wall of the processing tank, and screw holes are provided at the bottom end of the support rods.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The second humidification component delivers air with a certain humidity to the processing tank and blows the humid air evenly and finely onto the rice flowing in an S-shaped path inside the processing tank, thereby humidifying and softening the rice. The guide plate ensures that the rice flows downward in an S-shaped path inside the processing tank, effectively increasing the residence time of the rice inside the processing tank, thus improving the full contact between the rice and the humid air and enhancing the overall softening effect of the rice.

[0016] 2. The first humidification component sprays the humidified airflow evenly and finely from bottom to top onto the rice on the top surface of the guide plate, increasing the blowing direction of the humidified airflow, thereby increasing the movement of the rice and further improving the uniformity of the rice distribution when flowing inside the processing tank. This further improves the sufficiency and uniformity of the contact between the rice and the humidified airflow, and further improves the overall moistening and roughening effect of the rice.

[0027] See attached document Figure 1-5 A rice processing and humidification device includes a processing tank 3 with openings at both the top and bottom. Multiple staggered guide plates 8 are fixed to the two opposite inner walls of the processing tank 3, each guide plate 8 arranged at an angle with a gap between one end of each guide plate and the inner wall of the processing tank 3. The gaps between adjacent guide plates 8 and the inner wall of the processing tank 3 are staggered. A first humidification component 1 is installed inside the processing tank 3 to blow air onto the rice, and a second humidification component 2 is installed on the side of the processing tank 3 to humidify the rice. In use, the rice to be processed is fed into the processing tank 3 from the top opening, flowing in from the top opening and out from the bottom opening. During this process, the second humidification component 2 humidifies the rice to a certain moisture content. Airflow is delivered into the processing tank 3, and the humidified airflow is evenly and finely blown into the rice flowing in an S-shaped path inside the processing tank 3, thereby humidifying and softening the rice. The guide plate 8 ensures that the rice flows downward in an S-shaped path inside the processing tank 3, effectively increasing the residence time of the rice inside the processing tank 3, thus improving the fullness of contact between the rice and the humidified airflow and enhancing the overall softening effect of the rice. At the same time, the first humidification component 1 evenly and finely sprays the humidified airflow from bottom to top onto the rice on the top surface of the guide plate 8, increasing the blowing direction of the humidified airflow and thus increasing the movement of the rice, further improving the uniformity of the rice distribution when flowing inside the processing tank 3, thereby further improving the fullness and uniformity of contact between the rice and the humidified airflow, and further enhancing the overall softening effect of the rice.

[0028] Further as Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that the first humidification component 1 includes a second cavity 103 opened in the side wall of the processing tank 3, and the second humidification component 2 includes a blower plate 201 embedded in the side wall of the processing tank 3. Multiple blower plates 201 are provided and spaced apart between multiple guide plates 8. A third cavity 204 is opened inside the blower plate 201. Second air holes 203 communicating with the third cavity 204 are opened on the side of the blower plate 201 facing the center of the processing tank 3. Multiple second air holes 203 are provided and equidistantly distributed. In actual operation, a humidification pump is connected to the external air supply pipe 5. A humidified airflow with a certain pressure is delivered to the second cavity 103 through the air supply pipe 5, and then connected to multiple air blowing plates 201. The humidified airflow is evenly delivered to the processing tank 3 through multiple second air blowing holes 203 on the air blowing plates 201, and then evenly and finely blown out onto the rice flowing in an S-shaped path inside the processing tank 3, thereby humidifying and softening the rice. The guide plate 8 makes the rice flow downward in an S-shaped path inside the processing tank 3, effectively increasing the residence time of the rice inside the processing tank 3, thereby effectively increasing the full contact between the rice and the humidified airflow and improving the overall softening effect of the rice.

[0029] Further as Figure 5 As shown, it is worth noting that a protruding tube 202 is fixed on the blower plate 201. The protruding tube 202 extends into the second cavity 103 and is connected to the second cavity 103. In specific operation, the humid airflow inside the second cavity 103 is synchronously transported to the interior of multiple blower plates 201 through the protruding tube 202.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that each of the multiple guide plates 8 has a first cavity 102 communicating with the second cavity 103. The top surface of the guide plate 8 has a first air blowing hole 101 communicating with the first cavity 102. An air supply pipe 5 communicating with the second cavity 103 is fixed on the outer wall of the processing tank 3. Multiple first air blowing holes 101 are provided and are equidistantly distributed. In specific operation, the humid airflow inside the second cavity 103 is synchronously transported to the first cavity 102 of the multiple guide plates 8, and the humid airflow is evenly and finely sprayed from bottom to top onto the rice on the top surface of the guide plate 8 through the multiple first air blowing holes 101. This increases the blowing direction of the humid airflow, thereby increasing the movement of the rice and further improving the uniformity of the rice distribution when flowing inside the processing tank 3. This further improves the sufficiency and uniformity of the contact between the rice and the humid airflow, and further improves the overall moistening and roughening effect of the rice.

[0031] This solution includes the following working process: Rice to be processed is fed into the processing tank 3 from the top. The rice enters through the top opening and flows out through the bottom opening. A humidified airflow with a certain pressure is transported through the air supply pipe 5 to the second cavity 103, and then connected to multiple air blowing plates 201. The humidified airflow is evenly distributed into the processing tank 3 through multiple second air blowing holes 203 on the air blowing plates 201, and then evenly and finely blown onto the rice flowing in an S-shaped path inside the processing tank 3, thereby humidifying and moistening the rice. The guide plate 8 further facilitates the process... The rice flows downwards in an S-shaped path inside the processing tank 3, effectively increasing the residence time of the rice inside the processing tank 3, thereby effectively improving the sufficiency of contact between the rice and the humid airflow. The humid airflow inside the second cavity 103 is simultaneously transported to the first cavity 102 of multiple guide plates 8, and sprayed evenly and finely from bottom to top onto the rice on the top surface of the guide plates 8 through multiple first air holes 101, increasing the blowing direction of the humid airflow, thereby increasing the degree of movement of the rice, further improving the uniformity of the distribution of the rice when it flows inside the processing tank 3, and thus further improving the sufficiency and uniformity of contact between the rice and the humid airflow.

[0032] Further as Figure 1 and Figure 2 As shown, it is worth noting that two symmetrically distributed support rods 6 are fixed on the outer wall of the treatment tank 3, and screw holes 7 are opened at the bottom of the support rods 6; in actual operation, the treatment tank 3 is fixedly installed by installing screws in the screw holes 7.

[0033] In summary: The second humidifying component 2 delivers air with a certain humidity to the processing tank 3, and evenly and finely blows the humidified airflow into the rice flowing in an S-shaped path inside the processing tank 3, thereby humidifying and softening the rice. The guide plate 8 ensures that the rice flows downward in an S-shaped path inside the processing tank 3, effectively increasing the residence time of the rice inside the processing tank 3, thus improving the fullness of contact between the rice and the humidified airflow and enhancing the overall softening effect of the rice. At the same time, the first humidifying component 1 evenly and finely sprays the humidified airflow from bottom to top onto the rice on the top surface of the guide plate 8, increasing the blowing direction of the humidified airflow and thus increasing the movement of the rice, further improving the uniformity of the rice distribution when flowing inside the processing tank 3, thereby further improving the fullness and uniformity of contact between the rice and the humidified airflow, and further enhancing the overall softening effect of the rice.
