Description

Technical Field

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

[0002] Edible oil, as an indispensable basic element of modern diet, has its quality directly related to national health and food safety. In the complete industrial chain of edible oil processing, efficient and gentle pre-treatment drying of raw materials such as sesame and peanuts is the first key process concerning oil yield, oil flavor, and nutrient retention. Although traditional hot air drying technology is widely used, it often faces common industry bottlenecks in energy consumption control, drying uniformity, and the level of automation. In the edible oil extraction process, drying pre-treated oilseeds such as sesame and peanuts is an indispensable key step before pressing or leaching. This process aims to precisely control the moisture content of the raw materials, which not only creates the necessary conditions for subsequent efficient crushing and rolling, but also directly affects the oil yield and the stability of oil quality.

[0003] Existing hot air drying equipment commonly uses fixed box or tower structures. Materials within the drying chamber are typically in a static, piled-up or limited, spread-out state. This relatively static material layout results in high flow resistance and uneven distribution of hot air as it penetrates the material layer, limiting the contact area and efficiency between the material and the hot air. This leads to a series of problems, including uneven drying, excessive energy consumption, and oil coking due to localized overheating, which negatively impacts the flavor of the oil. Furthermore, even if the oil undergoes preliminary cleaning and washing before drying, it is still difficult to completely clean it during subsequent conveying, lifting, and entry into the drying equipment. To completely avoid the fine powder and debris generated by adhesion to the inner wall of the equipment and friction and breakage of materials, in traditional stationary drying equipment, these light-weight fine particles cannot be effectively separated. In the static or semi-static material layer, they are subjected to the drying airflow along with the main material. These powder and debris filling the gaps between materials will seriously hinder the uniform penetration and flow of hot air in the material layer, forming a local barrier. This makes it difficult for the core material to come into contact with sufficient hot air, thus aggravating the unevenness of drying as a whole and restricting further improvement of drying efficiency. To this end, we propose a hot air drying equipment for edible oil processing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a hot air drying device for edible oil processing, including a mounting frame, a mesh barrel rotatably mounted inside the mounting frame, a toothed ring sleeved on the mesh barrel, a drive wheel rotatably mounted inside the mounting frame, the drive wheel meshing with the toothed ring, an air inlet pipe fixedly mounted on the mounting frame, the air inlet pipe being coaxially arranged with the mesh barrel, and a spiral propulsion plate being provided inside the mesh barrel.

[0005] In some embodiments, mounting rings are fixedly installed at both ends of the spiral propulsion plate, and the two sets of mounting rings are correspondingly arranged at both ends of the mesh barrel. The mounting rings are fixedly connected to the mesh barrel by bolts, and the number of bolts is four sets, and the four sets of bolts are symmetrically distributed.

[0006] In some embodiments, a roller brush is rotatably mounted on the mounting frame, the roller brush being in contact with the surface of the mesh barrel, a rotating frame is rotatably mounted inside the mounting frame, and three sets of circularly distributed sweeping brushes are fixedly mounted on the rotating frame, the sweeping brushes being in contact with the roller brush, and gears are sleeved on the rotating frame.

[0007] In some embodiments, a rack is slidably mounted on the mounting bracket, the rack meshing with a gear, and a cylinder is fixedly mounted inside the mounting bracket, with the rack fixedly connected to the output end of the cylinder piston rod.

[0008] In some embodiments, two sets of symmetrically distributed movable frames are slidably installed in the mounting frame. The two sets of movable frames are respectively arranged corresponding to the two sets of sweeping brushes below. The mounting frame is provided with two sets of lead screws corresponding to the movable frames. The two ends of the lead screws pass through the mounting frame and are rotatably connected to the mounting frame through rolling bearings. The lead screws pass through the corresponding movable frames and are threadedly connected to the movable frames.

[0009] In some embodiments, a scraper block is slidably installed inside the movable frame, the scraper block is slidably sleeved with a corresponding brush, a cam is rotatably installed on the movable frame, the cam is fitted with the scraper block, and a slide rod is fixedly installed inside the movable frame.

[0010] In some embodiments, the scraper block is slidably sleeved with the slide rod, and two sets of symmetrically distributed springs are sleeved on the slide rod, with the two ends of the two sets of springs respectively fixedly connected to the scraper block and the movable frame.

[0011] This utility model has at least the following beneficial effects: 1. Through the meshing transmission of the drive wheel and the gear ring, the screen barrel rotates within the mounting frame. Simultaneously, the internally installed spiral propulsion plate continuously tumbles and propels the oil to be dried within the screen barrel, significantly increasing the contact area and time between the material and the hot air. This effectively solves the problems of uneven drying and high energy consumption caused by static or spread materials in traditional fixed drying equipment. The air inlet pipe is coaxially arranged with the screen barrel, further ensuring that the hot air penetrates the material layer evenly and smoothly, improving drying efficiency and quality stability. Furthermore, the spiral propulsion plate is fixedly connected to the screen barrel through mounting rings at both ends and multiple symmetrically distributed bolts, ensuring a stable structure and facilitating disassembly, cleaning, or replacement. This effectively addresses potential blockages caused by impurities such as mud and stems mixed in the raw materials, reducing maintenance difficulty and ensuring continuous and stable production.

[0012] 2. The uniformly distributed mesh drum effectively screens particles mixed in with the raw materials, preventing the problem of fine powder in the oil adhering to or clogging the mesh and affecting the hot air penetration efficiency. The rotating roller brush, which is in contact with the surface of the mesh drum, effectively removes impurities attached to the drum, preventing mesh clogging and maintaining the effective screening function of the mesh drum during the drying process. The reciprocating motion of the rack driven by the cylinder drives the gear and the rotating frame to rotate, so that the three sets of ring-shaped brushes can take turns to contact the roller brush on the working side, achieving continuous and effective cleaning. On the non-working side, the moving frame drives the scraper to clean. The moving frame can move laterally under the drive of the screw, so that the scraper slides along the brush and scrapes off the impurities attached to the brush. During the movement, the scraper is periodically pushed by the cam and reset by the spring, generating a high-frequency vibration, which quickly shakes off the scraped impurities, preventing secondary adhesion and ensuring the cleanliness and continuous working capacity of the brush itself, further improving the self-cleaning efficiency and long-term operational reliability of the entire drying system.

[0015] 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.

[0016] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a hot air drying device for edible oil processing, including a mounting frame 1, a mesh barrel 2 rotatably mounted inside the mounting frame 1, a toothed ring 19 sleeved on the mesh barrel 2, a drive wheel 20 rotatably mounted inside the mounting frame 1, the drive wheel 20 meshing with the toothed ring 19, an air inlet pipe 3 fixedly mounted on the mounting frame 1, the air inlet pipe 3 being coaxially arranged with the mesh barrel 2, and a spiral propulsion plate 5 provided inside the mesh barrel 2. When the motor on the mounting frame 1 is started, the drive wheel 20 is driven to rotate, and through the meshing toothed ring 19, the entire mesh barrel 2 is driven to rotate slowly inside the mounting frame 1. At the same time, hot air is sent into the inside of the mesh barrel 2 from the air inlet pipe 3. The material inside the mesh barrel 2 is turned over as the mesh barrel 2 rotates, and is also pushed forward by the fixed spiral propulsion plate 5. In this process, the hot air penetrates the tumbling material layer, takes away the moisture, and achieves dynamic and uniform drying.

[0017] Both ends of the spiral propulsion plate 5 are fixedly equipped with mounting rings 6. The two sets of mounting rings 6 are correspondingly set at both ends of the mesh barrel 2. The mounting rings 6 are fixedly connected to the mesh barrel 2 by bolts 7. There are four sets of bolts 7, and the four sets of bolts 7 are symmetrically distributed. The spiral propulsion plate 5 is positioned by the mounting rings 6 at both ends and is fastened to the inner wall of the mesh barrel 2 by the four sets of symmetrically distributed bolts 7. This connection method ensures the structural stability of the spiral propulsion plate 5 under the high-speed rotation of the mesh barrel 2 and the friction of materials. When it is necessary to clean the inside of the mesh barrel 2 or replace the spiral propulsion plate 5, it can be disassembled simply by loosening the bolts 7, which is convenient for maintenance.

[0018] A roller brush 4 is rotatably mounted on the mounting frame 1, and the roller brush 4 is set in close contact with the surface of the mesh barrel 2. A rotating frame 8 is rotatably mounted inside the mounting frame 1, and three sets of circularly distributed sweeping brushes 9 are fixedly mounted on the rotating frame 8, with the sweeping brushes 9 in close contact with the roller brush 4. A gear 10 is sleeved on the rotating frame 8, and a rack 11 is slidably mounted on the mounting frame 1, meshing with the gear 10. A cylinder 12 is fixedly mounted inside the mounting frame 1, and the rack 11 is fixedly connected to the output end of the piston rod of the cylinder 12. The roller brush 4 rotates close to the outer surface of the mesh barrel 2 to remove impurities clogging the mesh. The roller brush 4 with impurities is cleaned by the sweeping brushes 9. When a set of sweeping brushes 9 has too much impurity due to cleaning the roller brush 4, the cylinder 12 pushes the rack 11 to move linearly, and the rack 11 drives the gear 10 to rotate, thereby driving the rotating frame 8 to rotate 120 degrees, switching a set of clean sweeping brushes 9 to the working position to contact the roller brush 4, so as to achieve continuous cleaning.

[0019] Example 2: Please refer to Figure 3 , Figure 4Two sets of symmetrically distributed movable frames 13 are slidably installed inside the mounting frame 1. The two sets of movable frames 13 are respectively set to correspond to the two sets of sweeping brushes 9 below. The mounting frame 1 is provided with two sets of lead screws 14 corresponding to the movable frames 13. The two ends of the lead screws 14 pass through the mounting frame 1 and are rotatably connected to the mounting frame 1 through rolling bearings. The lead screws 14 pass through the corresponding movable frames 13 and are threadedly connected to the movable frames 13. When the sweeping brush 9 is in the non-working position, it faces the movable frame 13. The lead screws 14 are driven to rotate by external power. Through the threaded engagement with the movable frames 13, the movable frames 13 are driven to move horizontally along the axis of the lead screws 14, so that the scraper blocks 15 installed on the movable frames 13 can traverse the entire working surface of the sweeping brush 9.

[0020] A scraper block 15 is slidably installed inside the movable frame 13, and the scraper block 15 is slidably sleeved with the corresponding brush 9. A cam 18 is rotatably installed on the movable frame 13, and the cam 18 is fitted with the scraper block 15. A slide rod 16 is fixedly installed inside the movable frame 13, and the scraper block 15 is slidably sleeved with the slide rod 16. Two sets of symmetrically distributed springs 17 are sleeved on the slide rod 16, and the two ends of the two sets of springs 17 are fixedly connected to the scraper block 15 and the movable frame 13, respectively. During the movement of the movable frame 13, the scraper block 15 is tightly... The bristles of the brush 9 scrape off the impurities attached to it. At the same time, the cam 18 rotates continuously, periodically squeezing the scraper block 15, forcing the scraper block 15 to slide away from the brush 9 along the slide bar 16 against the force of the spring 17. When the cam 18 turns to the non-squeezing point, the spring 17 pushes the scraper block 15 to return to its original position. This reciprocating motion causes the scraper block 15 to vibrate at high frequency, thereby shaking off the collected impurities from the scraper block 15, preventing them from accumulating, and keeping the scraper block 15 clean and effective.
