Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a drying device for rice processing. Background Technology

[0002] Rice drying is a crucial step in rice processing and storage. Its core purpose is to reduce the moisture content of rice (usually controlled below 14%) to prevent mold and pests, extend shelf life, and ensure rice quality and food safety. Currently, large-scale production commonly uses drying equipment such as tower dryers and fluidized bed dryers to adapt to large-scale industrial production. These dryers allow for temperature and air speed adjustment, enabling continuous drying operations.

[0003] However, in the material conveying process of existing drying equipment, when rice is evenly spread onto the conveyor belt by the feeding device, the thickness of the rice is prone to local unevenness due to factors such as feeding speed, conveyor belt inclination angle, and rice variety (e.g., differences in grain shape and flowability). This unevenness leads to differences in heat exchange efficiency, causing some rice to be over-dried (causing cracks) or under-dried (leaving moisture), directly affecting the processing quality of the finished rice (e.g., rice yield, cooking rate, etc.).

[0004] In existing technologies, the problem of uneven rice layer thickness has not been solved. Generally, pressure rollers are installed above the conveyor belt. The rice layer is compressed by the gap formed by the rotation of the pressure rollers and their cooperation with the conveyor belt, thereby compacting the rice to the target thickness and avoiding uneven drying.

[0005] However, using pressure rollers to level the rice layer on the conveyor belt to a suitable thickness may increase the breakage rate of the rice (especially for rice varieties with high brittleness, such as long-grain rice and old rice). Furthermore, if there is residual grease, dust, or other impurities on the surface of the pressure rollers, cross-contamination may easily occur when processing different batches or varieties of rice, affecting food safety. Utility Model Content

[0006] In view of this, the present invention provides a drying device for rice processing, which can solve the problem of uneven rice layer by initial leveling with a flat plate and secondary dynamic adjustment with a baffle plate, avoid heat exchange differences, reduce rice cracks and moisture residue, and significantly improve drying uniformity and processing quality.

[0007] To solve the above-mentioned technical problems, this utility model provides a drying device for rice processing, including a dryer body. The dryer body includes two baffles, a conveyor belt is arranged between the two baffles, and a mounting frame is arranged on the upper part of the two baffles and above the conveyor belt. Mounting plates are fixedly connected to both sides of the bottom of the mounting frame, and the mounting plates are detachably connected to the upper part of the baffles by bolts.

[0008] Two mounting slots are cut through the mounting frame, and a flat plate is slidably connected in the mounting slot for initial thickness leveling of the rice layer. Two flat plates are also set, which reduces the production cost of the equipment while ensuring the leveling effect and facilitating maintenance.

[0009] Several diversion channels are evenly distributed on the flat plate. The diversion channels on every two adjacent flat plates are staggered to achieve the initial uniform laying of the meter layer on the conveyor belt through the guiding effect of the diversion channels.

[0010] The entire flat plate is made of food-grade silicone, which can come into direct contact with rice, and its smooth surface makes it easy to clean up any rice residue.

[0011] A limiting plate is fixedly connected to the upper part of the plate, and the limiting plate is detachably connected to the upper part of the mounting frame by bolts.

[0012] A leveling mechanism is installed on one vertical surface of the mounting frame to level the rice layer laid on the conveyor belt again. The leveling mechanism includes a support plate installed on one vertical surface of the mounting frame. The support plate is connected to the vertical surface of the mounting frame by a fixing plate. The fixing plate is detachably connected to the mounting frame by bolts. A baffle plate is bolted to the lower part of the support plate. The thickness of the rice layer is dynamically adjusted by the gap formed with the surface of the conveyor belt to achieve secondary leveling.

[0013] The bottom of the baffle plate is tilted away from the mounting frame, so that the rice layer is naturally flattened under the action of gravity and conveying force, avoiding deformation and damage of the rice layer caused by rigid compaction.

[0014] Side plates are fixedly connected to both sides of the baffle plate to prevent rice from overflowing to both sides during the leveling process, ensuring the uniformity of the rice layer width.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] 1. Double leveling structure improves drying uniformity: The initial thickness leveling is achieved through the leveling plate on the mounting frame, and the secondary dynamic thickness adjustment is achieved with the baffle plate of the leveling mechanism. The double leveling mechanism effectively solves the problem of uneven rice layer thickness in traditional drying equipment, avoids the difference in heat exchange efficiency caused by local excessive thickness or thinness, reduces the situation of rice cracking due to over-drying or residual moisture due to insufficient drying, and significantly improves the uniformity of rice drying and processing quality.

[0017] 2. Optimized distribution channel design for initial rice layer laying: The distribution channels evenly opened on the flat plate are staggered to guide the rice grains to disperse through the guiding effect, refine the flow trajectory, and make the rice layer on the conveyor belt form a more uniform thickness distribution in the initial leveling stage. This provides a stable foundation for subsequent secondary leveling, reduces the problem of rice grain accumulation or uneven distribution from the source, and improves the material pretreatment effect before drying.

[0018] 3. Food-grade silicone material ensures safety and convenience: The entire plate is made of food-grade silicone material, which is non-toxic, harmless, and has a smooth surface. It meets food contact safety standards, avoiding contamination when in contact with rice and ensuring food safety. At the same time, the flexibility of silicone material makes it slide with low resistance in the installation groove, which is convenient for height adjustment and position replacement. It also has good self-cleaning properties, making it easy to clean residual rice, reducing equipment maintenance costs and improving ease of operation.

[0019] 4. Detachable structure improves equipment maintenance efficiency: The entire platen is detachably connected to the mounting frame via limit plates and bolts. Components such as the leveling mechanism's support plates and baffles are also bolted together, facilitating quick disassembly and replacement. When adjusting the layer thickness, cleaning components, or maintaining the equipment, operations can be completed efficiently, reducing downtime and meeting the needs of convenient maintenance and flexible adjustment in industrial production.

[0020] 5. Inclined baffles and side plates reduce rice grain breakage and ensure uniform width: The bottom of the baffle is inclined away from the mounting frame, using the weight of the rice and the conveyor belt to naturally flatten the rice layer, avoiding the deformation and breakage of rice grains caused by the rigid compaction of traditional pressure rollers. This is especially suitable for brittle varieties such as long-grain rice and old rice, reducing the breakage rate. The side plates on both sides block the rice that overflows during the leveling process, ensuring that the rice layer is evenly distributed in the width direction, further improving the drying consistency.

[0021] 6. Low cost and high reliability design: The flat plate is set as two pieces, which reduces material usage and processing costs while ensuring the leveling effect; the components are connected by bolts to achieve modular installation, reducing equipment manufacturing and maintenance costs. At the same time, the combination of silicone material and inclined baffle plate improves the long-term reliability of the equipment and adapts to the high-intensity production needs of large-scale rice processing.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0032] A drying device for rice processing, such as Figure 1 , 2 As shown: It includes a dryer body 100 for drying rice. The dryer body 100 includes two baffles 101 and a conveyor belt is arranged between the two baffles 101. The conveyor belt is used to transport the rice to the drying mechanism for drying.

[0033] An installation frame 102 is provided on the upper part of the two baffles 101 and above the conveyor belt. The installation frame 102 is located on one side of the drying mechanism and on the side where rice is added. The bottom sides of the installation frame 102 are fixedly connected to the installation plates 106. The installation plates 106 are detachably connected to the upper part of the baffles 101 by bolts, so that the installation frame 102 can be quickly disassembled and assembled when maintenance or repositioning is required.

[0034] like Figure 2 , 3 As shown: In this embodiment, two mounting slots 103 are formed through the mounting frame 102. A flat plate 104 is slidably connected in the mounting slots 103 for initial thickness leveling of the rice layer. The height of the flat plate 104 can be adjusted according to the different conditions of the dryer body during use, so as to further control the thickness of the rice layer. This allows the rice layer to be leveled to a suitable thickness during the initial leveling, so that the rice can be dried evenly.

[0035] In this embodiment, the flat plate 104 is also set to two pieces, which reduces the production cost of the equipment while ensuring the leveling effect. In addition, since there are fewer pieces of flat plate 104, it is easier to maintain and adjust them later.

[0036] like Figure 3 As shown: Several diversion grooves 105 are evenly distributed on the flat plate 104. The diversion grooves 105 guide the rice layer on the conveyor belt to achieve initial dispersion during movement, avoiding the problem of rice grain accumulation or uneven distribution. The diversion grooves 105 on every two adjacent flat plates 104 are staggered. Through the cross distribution of the flow path, the flow trajectory of the rice grains is further refined, so that the rice grains form a more uniform initial thickness adjustment on the conveyor belt, providing a basis for subsequent secondary thickness leveling, so that the initial uniform laying of the rice layer on the conveyor belt can be achieved through the guiding effect of the diversion grooves 105.

[0037] like Figure 3 As shown: The flat plate 104 is made of food-grade silicone, enabling it to withstand the continuous impact and pressure of the rice layer accumulating on the conveyor belt. This prevents the flat plate 104 from deforming due to long-term stress, ensuring the stability of the flat plate 104 in leveling the rice layer thickness and the long-term reliable operation of the equipment.

[0038] The food-grade silicone material is non-toxic, harmless, and odorless, meeting food contact safety standards and will not contaminate the rice, ensuring the quality and safety of the rice during the drying process. At the same time, the smooth surface of the silicone material has a certain degree of self-cleaning property, making it difficult for rice grains to adhere to the plate 104, which facilitates equipment cleaning and maintenance. In addition, its flexibility means that the plate 104 has low resistance when sliding and adjusting within the mounting groove 103, making it easy to adjust the height and change the position, thus improving the ease of operation (different lengths of plate 104 can be used when adjusting the height).

[0039] like Figure 3 , 4 As shown: A limiting plate 201 is fixedly connected to the upper part of the plate 104, so that the plate 104 can be supported during use and prevented from falling out of the mounting groove 103 during use. The limiting plate 201 is detachably connected to the upper part of the mounting frame 102 by bolts, so that the plate 104 is limited and can be quickly disassembled and assembled when the plate 104 needs to be replaced or its position adjusted.

[0040] like Figure 3 , 4 As shown in Figure 5, a leveling mechanism is provided on one vertical surface of the mounting frame 102 to level the rice layer laid on the conveyor belt again, so that the rice layer can be leveled to a suitable thickness when it enters the drying mechanism, and further avoids uneven drying.

[0041] The leveling mechanism includes a support plate 302 set on a vertical surface on one side of the mounting frame 102. The support plate 302 is connected to the vertical surface on one side of the mounting frame 102 by a fixing plate 301. The fixing plate 301 is detachably connected to the mounting frame 102 by bolts, so that the support plate 302 can be quickly removed from the mounting frame 102 when maintenance or replacement is required.

[0042] A baffle plate 303 is bolted to the lower part of the support plate 302. The baffle plate 303 dynamically adjusts the thickness of the rice layer by forming a gap with the surface of the conveyor belt, thereby achieving secondary leveling. That is, the baffle plate 303 blocks the dispersed rice layer for secondary thickness leveling through its bottom. Furthermore, the bolted connection allows for quick disassembly and assembly of the baffle plate 303 when changing to different lengths (i.e., when adjusting the rice layer thickness according to different drying equipment).

[0043] like Figure 4 , 5 As shown: The bottom of the baffle plate 303 is inclined towards the side away from the mounting frame 102, so that the rice layer is naturally flattened under the action of gravity and conveying force, avoiding deformation and damage of the rice layer caused by rigid compaction.

[0044] Side plates 401 are fixedly connected to both sides of the baffle plate 303 to block the rice from overflowing to both sides during the leveling process and ensure the uniformity of the rice layer width.

[0045] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
