Description

Technical Field

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

[0002] In peanut processing, uniform drying is a key step in ensuring peanut quality and storage safety. Traditional drying equipment often uses static baking or simple hot air circulation, which can easily lead to peanut stacking, uneven heating, and localized scorching or undried conditions. This affects the color, taste, and shelf life of the finished product. In addition, there is a risk of steam condensation dripping, causing secondary moisture absorption and dust contamination of the peanuts. It is difficult to meet the dual requirements of efficiency and quality for large-scale production.

[0003] While existing peanut drying equipment achieves continuous operation through conveyor belt transport, it generally suffers from the following core problems: peanuts tend to clump together due to gravity during transport, causing hot air to penetrate only the surface while the inside remains damp, resulting in uneven drying; simultaneously, the hot air flow is obstructed in the stacked areas, leading to excessively high local temperatures that can cause peanut oxidation and spoilage, while undried areas are at risk of mold growth; although some devices attempt to reduce stacking through mechanical dispersion, traditional single-pass dispersion or fixed-frequency vibration methods cannot maintain a single-layer distribution of peanuts and lack an immediate mechanism for removing water vapor from the drying area. The condensed steam easily adheres to the conveyor belt or peanut surface, further exacerbating uneven heating; these problems collectively result in low drying efficiency and large fluctuations in finished product quality, making it difficult to meet the industrial application requirements for uniform peanut drying. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a peanut processing device for uniform drying, so as to solve the technical problem in the prior art that peanuts are easily piled up during the transportation process, resulting in uneven hot air penetration and steam condensation dripping, causing secondary moisture absorption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a peanut processing device for uniform drying, comprising a base, an installation frame on the base, a feeding hopper for feeding peanuts on the installation frame, a conveyor belt for transporting peanuts in the installation frame, the conveyor belt being located below the feeding hopper, a guide frame in the installation frame, the guide frame being located beside the conveyor belt, and a collection frame for collecting dried peanuts being located below the guide frame; The mounting frame is provided with a bracket, and a drying component for drying peanuts conveyed on the conveyor belt is provided above the bracket. The drying component includes a fixed frame provided at the top of the bracket, and an electric heating roller for heating the air entering the mounting frame is provided in the fixed frame. The bottom of the support is provided with a dispersion and anti-stacking component to disperse the peanuts conveyed on the conveyor belt. The dispersion and anti-stacking component includes multiple connecting frames set at the bottom of the support. Each connecting frame is movably provided with a movable plate. The bottom end of the movable plate is provided with a dispersion roller. The bottom end of the dispersion roller contacts the top end of the conveyor belt. When the movable plate slides back and forth in the connecting frame, the spreading roller spreads the peanuts so that they are dried evenly. Preferably, the drying assembly includes a connecting frame disposed on a fixed frame, and an electric fan is disposed inside the connecting frame; The air blown by the electric fan is directed towards the inside of the mounting frame; Preferably, a mounting bracket is provided on the top of the connecting frame, and a filter screen is slidably disposed inside the mounting bracket to prevent external dust from entering the connecting frame, and a handle is provided on the side of the filter screen; Preferably, the anti-stacking assembly includes a connecting rod rotatably disposed in multiple connecting frames, and multiple incomplete gears are disposed on the outside of the connecting rod; Each movable plate has a rack fixed to its top, and each rack meshes with one of the incomplete gears; When the connecting rod rotates, the incomplete gear and the rack are in a meshing transmission state; Preferably, a spring is provided in the connecting frame, and the two ends of the spring are fixedly connected to the outside of the connecting frame and the movable plate, respectively; When the incomplete gear loses engagement with the rack, the spring returns to its original length, and the movable plate slides in the opposite direction in the connecting frame; Preferably, a drive motor is provided on the top of the bracket, and pulleys are provided on the output shaft of the drive motor and the end of the connecting rod. The two pulleys are externally connected by a synchronous belt. Each connecting frame is equipped with a fixing frame on the side, and the fixing frame is equipped with a telescopic rod. The output end of the telescopic rod is fixed with an elastic plate to flatten the peanuts being transported. Preferably, the mounting frame is provided with a water vapor removal component for removing water vapor generated during the drying process. The water vapor removal component includes a support seat on the mounting frame, an exhaust fan on the support seat, a connecting pipe fixed to the air inlet end of the exhaust fan, and an exhaust head fixed to the end of the connecting pipe away from the exhaust fan. The exhaust head is located at the bottom of the conveyor belt.

[0006] In summary, the present invention has the following main advantages: 1. This utility model utilizes the intermittent meshing transmission of incomplete gears and racks, combined with the spring rebound mechanism, to achieve the reciprocating motion of the spreading roller. This motion continuously spreads the stacked layers during peanut transport, and, in conjunction with the secondary leveling by the elastic plate, ensures that the peanuts are evenly distributed in a single layer. This guarantees that hot air can penetrate the entire peanut layer, avoiding uneven drying or mold risk caused by localized accumulation, and improving drying efficiency and finished product quality.

[0007] 2. The steam removal component in this invention continuously extracts water vapor from the bottom area of ​​the conveyor belt using an exhaust fan, effectively preventing condensate from accumulating inside the device and avoiding backflow of water vapor that could affect the drying effect. Simultaneously, the sliding filter screen can be manually opened and closed, blocking external dust from entering during the drying process and ensuring that the peanuts are dried in a clean environment. These two measures work together to ensure the continuity of the drying process and maintain the hygiene and safety standards of the peanuts. Attached Figure Description

[0011] The embodiments of this utility model will be described below based on its overall structure.

[0012] Example 1 Please see Figures 1-5 This utility model provides a technical solution: a peanut processing device for uniform drying, including a base 11, an installation frame 12 on the base 11, a feeding hopper 13 for feeding peanuts on the installation frame 12, a conveyor belt 21 for transporting peanuts in the installation frame 12, the conveyor belt 21 being located below the feeding hopper 13, a guide frame 22 being located beside the conveyor belt 21 in the installation frame 12, and a collection frame 23 for collecting dried peanuts being located below the guide frame 22; the vertical arrangement of the feeding hopper 13 and the conveyor belt 21 ensures uniform initial feeding of peanuts and reduces the risk of stacking; the cooperation of the guide frame 22 and the collection frame 23 enables directional collection of dried peanuts, improving process continuity; A support frame 3 is provided on the mounting frame 12. A drying assembly 31 for drying peanuts conveyed on the conveyor belt 21 is provided above the support frame 3. The drying assembly 31 includes a fixed frame 311 at the top of the support frame 3. An electric heating roller 312 is provided in the fixed frame 311 to heat the air entering the mounting frame 12. The electric heating roller 312 forms hot air circulation by heating the air. With the support structure of the support frame 3, it ensures that the hot air evenly covers the peanuts on the conveyor belt 21, thereby improving the drying efficiency. The bottom of the support frame 3 is provided with a peanut-dispersing and anti-stacking component 32 to disperse the peanuts conveyed on the conveyor belt 21. The peanut-dispersing and anti-stacking component 32 includes multiple connecting frames 321 set at the bottom of the support frame 3. Each connecting frame 321 is movably equipped with a movable plate 322. The bottom end of the movable plate 322 is provided with a dispersing roller 323, and the bottom end of the dispersing roller 323 contacts the top end of the conveyor belt 21. The dispersing roller 323 continuously disperses the peanut stack layer by the reciprocating sliding of the movable plate 322 in the connecting frame 321, ensuring that hot air penetrates and avoiding local overheating or undried peanuts. When the movable plate 322 slides back and forth in the connecting frame 321, the spreading roller 323 spreads the peanuts to make them dry evenly. The reciprocating motion mechanism combined with the contact spreading of the spreading roller 323 achieves single-layer distribution of peanuts, optimizes the utilization rate of hot air, and reduces drying dead corners. Furthermore, the drying assembly 31 includes a connecting frame 313 mounted on the fixed frame 311, and an electric fan 314 is installed inside the connecting frame 313; the air blown by the electric fan 314 is directed toward the interior of the mounting frame 12; the electric fan 314 drives the hot air to flow in a directional manner, accelerates air circulation, and, in conjunction with the heating function of the electric heating roller 312, forms a highly efficient hot air blowing. Furthermore, a mounting bracket 315 is provided on the top of the connecting frame 313, and a filter screen 316 is slidably installed inside the mounting bracket 315 to prevent external dust from entering the connecting frame 313. A handle is provided on the side of the filter screen 316. The filter screen 316 is easy to clean through its sliding design, preventing dust from contaminating the peanuts and ensuring the cleanliness of the drying environment. Furthermore, the anti-stacking and anti-stacking assembly 32 includes a connecting rod 324 rotatably disposed in multiple connecting frames 321, and multiple incomplete gears 328 disposed on the outside of the connecting rod 324; a rack 3221 is fixed to the top of each movable plate 322, and each rack 3221 meshes with one of the incomplete gears 328; when the connecting rod 324 rotates, the incomplete gears 328 and racks 3221 are in a meshing transmission state; the meshing transmission of the incomplete gears 328 and racks 3221 realizes the intermittent movement of the movable plate 322, which, together with the spring 3222, forms a reciprocating anti-stacking power source; Furthermore, a spring 3222 is provided in the connecting frame 321, and the two ends of the spring 3222 are fixedly connected to the outside of the connecting frame 321 and the movable plate 322, respectively. When the incomplete gear 328 loses engagement with the rack 3221, the spring 3222 returns to its original length, and the movable plate 322 slides in the opposite direction in the connecting frame 321. The elastic rebound mechanism of the spring 3222 ensures that the movable plate 322 automatically resets when the gear drive is lost, forming a continuous and stable reciprocating motion, which improves the dispersing effect. Furthermore, a drive motor 325 is installed on the top of the support 3. The output shaft of the drive motor 325 and the end of the connecting rod 324 are both equipped with pulleys 326. The two pulleys 326 are externally connected to a synchronous belt 327. A fixing frame 3291 is installed on the side of each connecting frame 321. A telescopic rod 3292 is installed in the fixing frame 3291. An elastic plate 3293 for leveling the peanuts being transported is fixed to the output end of the telescopic rod 3292. The drive motor 325 drives the rotation of the connecting rod 324 through the pulleys 326 and the synchronous belt 327. With the secondary leveling by the elastic plate 3293, the peanut layer is ensured to be uniform and flat, thus improving the drying quality.

[0013] Example 2 Please see Figure 6Furthermore, in conjunction with Embodiment 1, the mounting frame 12 is provided with a water vapor removal component 33 for removing water vapor generated during the drying process. The water vapor removal component 33 includes a support base 331 mounted on the mounting frame 12, an exhaust fan 332 mounted on the support base 331, a connecting pipe 333 fixed to the air inlet end of the exhaust fan 332, and an exhaust head 334 fixed to the end of the connecting pipe 333 away from the exhaust fan 332. The exhaust head 334 is located at the bottom of the conveyor belt 21. The exhaust head 334 is located at the bottom of the conveyor belt 21 and continuously removes water vapor through the exhaust fan 332 to prevent condensate accumulation, keep the drying environment dry, and improve drying efficiency.

[0014] The working process of a peanut processing device for uniform drying: In the mounting frame 12 set on the base 11, the feed hopper 13 feeds the peanuts to be dried into the conveyor belt 21; the conveyor belt 21 is located below the feed hopper 13, and the peanuts enter the drying area after being transported; in the fixed frame 311 at the top of the support 3, the electric heating roller 312 heats the air entering the mounting frame 12, and the electric fan 314 inside the connecting frame 313 blows the hot air onto the peanuts on the conveyor belt 21; At this time, in the multiple connecting frames 321 at the bottom of the support 3, the movable plate 322 meshes with the incomplete gear 328 on the connecting rod 324 through the rack 3221; the drive motor 325 drives the connecting rod 324 to rotate through the pulley 326 and the synchronous belt 327, which in turn drives the incomplete gear 328 to rotate; when the teeth of the incomplete gear 328 contact the rack 3221, it pushes the movable plate 322 to slide along the connecting frame 321, compressing the spring 3222; when the teeth of the incomplete gear 328 disengage from the rack 3221, the spring 3222 returns to its original length, pushing the movable plate 322 to slide and rebound in the opposite direction, forming a reciprocating motion; when the movable plate 322 slides, the dispersing roller 323 at its bottom end contacts the top of the conveyor belt 21, dispersing the stacked peanuts, and in conjunction with the telescopic rod 3292 on the fixed frame 3291, pushes the elastic plate 3293 to flatten the peanuts, ensuring that hot air penetrates the peanut layer evenly; During the drying process, the water vapor removal component 33 on the mounting frame 12 is activated: the exhaust fan 332 on the support base 331 continuously extracts water vapor from the bottom area of ​​the conveyor belt 21 through the connecting pipe 333 and the exhaust head 334, so as to avoid water vapor condensation affecting the drying efficiency; the filter screen 316 is slidably set in the connecting frame 313 through the mounting bracket 315 and is controlled by the handle to prevent external dust from entering the drying area; The dried peanuts are conveyed to the end of the conveyor belt 21 and then slide down the guide frame 22 to the collection frame 23 for collection. The entire process uses the synergistic effect of hot air circulation, mechanical dispersion and steam removal, combined with the rebound mechanism of spring 3222 to realize the reciprocating motion of the dispersion roller 323, to ensure that the peanuts are dried evenly and without stacking. At the same time, the secondary leveling by the elastic plate 3293 further improves the drying uniformity. During the operation of the device, the movement of each component is automatically controlled by the drive motor 325 and the mechanical transmission mechanism to ensure the continuous and stable process.
