Abstract
Description
Technical Field
[0001] This utility model relates to the field of cereal processing technology, specifically to a stirring device for making cereal. Background Technology
[0002] Oatmeal is a sheet-like food made from grains (such as wheat, oats, barley, corn, etc.) through processes such as cleaning, dehulling, steaming, pressing, and drying. Mixed oatmeal is a compound product made by adding other ingredients to oatmeal, typically including dried fruit, nuts, milk powder, etc.
[0003] Making mixed cereal requires mixing various ingredients, and the key to this process lies in ensuring both uniform mixing and the integrity of the cereal. Current mixing devices are often large and designed for large-volume mixing at once. With such devices, increasing mixing uniformity requires longer mixing times, while maintaining cereal integrity necessitates avoiding fixed mixers and shortening mixing times. This creates a dilemma in mixed cereal production.
[0004] Therefore, it is necessary to change the design concept of the mixing device, which should focus on mixing small quantities. The time required for small quantities to be mixed evenly should be short enough to ensure both the uniformity of the mixture and the integrity of the oatmeal. At the same time, it is also necessary to solve the problem of low feeding and discharging efficiency when mixing small quantities, and it is best to achieve continuous automatic feeding and discharging.
[0005] Therefore, a mixing device for making oatmeal is designed, which can continuously mix small amounts of oatmeal and mixtures under automatic feeding and discharging conditions, while ensuring both mixing uniformity and oatmeal integrity. Utility Model Content
[0006] The purpose of this invention is to provide a stirring device for making oatmeal, in order to solve the problems described in the background art.
[0007] The technical solution of this utility model is implemented as follows:
[0008] A mixing device for making oatmeal includes a drive mechanism, a support component, and an inclined mixing drum. The upstream and downstream ends of the mixing drum are open, and the internal cavity of the mixing drum is cylindrical. The mixing drum is rotatably mounted on the support component. The drive mechanism drives the outer wall of the mixing drum, causing the mixing drum to rotate about the central axis of the internal cavity. The mixing drum has at least three partitions spaced from top to bottom along the central axis of the internal cavity. The partitions are parallel to each other and perpendicular to the central axis of the internal cavity. The edges of the partitions are sealed to the inner wall of the mixing drum. The edges of each partition... The device also includes a discharge port, and multiple lifting plates are provided on the inner wall of the mixing drum upstream of the partition. The lifting plates are arranged at equal angles around the central axis of the internal cavity. The mixing device also includes a feed hopper located above the upstream of the mixing drum. The bottom of the feed hopper is connected to the upstream opening of the mixing drum through a discharge pipe. The mixing device also includes multiple storage hoppers located above the feed hopper. A quantitative discharge mechanism is connected to the bottom of the storage hopper. The outlet of the quantitative discharge mechanism is connected to the inside of the feed hopper. The mixing device also includes a controller. The quantitative discharge mechanism and the controller are electrically connected.
[0009] When using the above scheme, various materials for mixing oatmeal are input into the storage hopper. Through the coordination of the controller and the quantitative discharge mechanism, the mixed materials in the storage hopper are simultaneously fed into the feeding hopper at a preset output rate within a preset time period. After entering the feeding hopper, the materials enter the mixing drum through the discharge pipe. The mixing drum, continuously driven by the drive mechanism, receives the materials, and the lifting plates continuously tumble and agitate them. Due to the inclined design of the mixing drum, the materials slide down to the baffles under gravity. The baffles briefly impede the material's fall, preventing stratification caused by the rapid descent of materials of different sizes and masses. During this brief period of obstruction, the lifting plates agitate the materials, thereby improving the mixing uniformity. Simultaneously, the agitation method of the lifting plates effectively prevents oatmeal breakage, improving oatmeal integrity. When the discharge port of the baffle rotates downwards, the materials continue to slide down through the discharge port. After being briefly obstructed by multiple baffles, the mixing uniformity of the materials continuously improves, and the materials are discharged from the last baffle, thus exiting the mixing drum.
[0010] Under the operation of this device, the quantitative discharge mechanism, in conjunction with the inclined mixing drum, conveniently achieves automatic feeding and discharging. Simultaneously, the material is mixed in small quantities each time in the mixing drum, ensuring thorough mixing within a short time. This mixing method also effectively prevents the cereal from breaking.
[0011] A further technical solution is that the discharge ports, starting from the uppermost partition, are sequentially offset along the circumference at predetermined angle intervals to form a spiral arrangement structure, and the rotation direction of the stirring drum is the same as the spiral direction formed by the multiple discharge ports.
[0012] When using the above scheme, the spiral arrangement of the discharge ports, combined with the co-rotation of the mixing drum, ensures that material sliding down from the discharge port of the upper baffle does not immediately enter the discharge port of the lower baffle, thus preventing the material from being discharged directly from the mixing drum without being agitated by the lifting plates. At the same time, the spiral arrangement maximizes the time the material is briefly blocked by the baffles, allowing technicians to systematically calculate design factors such as the mixing drum's rotational speed and the size of the discharge ports.
[0013] A further technical solution is that the driving mechanism includes a driven wheel fixedly sleeved on the outer wall of the mixing drum, a motor bracket and a first motor fixed on the motor bracket, and a driving wheel is provided on the output shaft of the first motor, and the driving wheel is driven by the driven wheel.
[0014] When using the above scheme, the first motor drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate, and the driven wheel drives the stirring drum to rotate.
[0015] A further technical solution is that both the driving wheel and the driven wheel are belt pulleys, and the driving wheel and the driven wheel are connected by a belt.
[0016] A further technical solution is that the supporting components include a front support frame and a rear support frame. The front support frame is located below the higher end of the mixing drum, and the rear support frame is located below the lower end of the mixing drum. A front groove seat is fixedly provided on the upper end of the front support frame, and a rear groove seat is fixedly provided on the upper end of the rear support frame. A front ring and a rear ring are respectively fixedly fitted on the outer wall of the mixing drum. A front ring groove is provided in the front groove seat for the front ring to rotate and be inserted into it. The front ring is rotatably installed in the front ring groove. A rear ring groove is provided in the rear groove seat for the rear ring to rotate and be inserted into it. The rear ring is rotatably installed in the rear ring groove.
[0017] When using the above scheme, the front and rear annular grooves work in conjunction with the front and rear circular rings to provide both support and rotation for the mixing drum.
[0018] A further technical solution is that the quantitative discharging mechanism includes a feeding pipe, one end of which is open and the other end is closed. The top of the feeding hopper has an opening, and the open end of the feeding pipe is located above the opening at the top of the feeding hopper. A discharge pipe is connected to the top of the feeding pipe near the closed end. The top of the discharge pipe is connected to the bottom of the storage hopper. A spiral shaft is also provided in the feeding pipe, one end of which extends to the open end. A second motor is also fixed to the outside of the closed end of the feeding pipe. The output shaft of the second motor rotates through the wall of the feeding pipe at the closed end. The other end of the spiral shaft is connected to the output shaft. The second motor is electrically connected to the controller.
[0019] When using the above scheme, the second motor drives the screw shaft to rotate, and the screw shaft pushes the material falling from the feeding pipe toward the open end. By controlling the speed of the screw shaft, quantitative discharge can be achieved.
[0020] A further technical solution is that a cone is connected to the upper end of the mixing drum. The opening of the cone at the end furthest from the mixing drum is smaller than the opening at the end closest to the mixing drum, and the discharge pipe is connected to the cone.
[0021] When using the above solution, the design of the cone can effectively prevent powdery materials from being thrown outwards.
[0022] The beneficial effects of this utility model are as follows:
[0023] 1. Automated feeding and discharging: Through the cooperation of the controller and the quantitative discharging mechanism, as well as the inclined mixing drum, the automatic feeding and discharging process of mixed oatmeal is realized, which improves production efficiency.
[0024] 2. High mixing uniformity: The material is continuously tumbled and stirred in the mixing drum by the lifting plates, and the temporary blocking effect of the baffles effectively prevents the stratification of materials of different particle sizes and masses, thus improving the mixing uniformity.
[0025] 3. Prevent cereal breakage: The mixing method of the lifting plate is reasonably designed, which can effectively prevent cereal breakage during the mixing process and maintain the integrity of the cereal.
[0026] 4. Small-volume, high-efficiency mixing: Each mixing operation involves small quantities of material, ensuring thorough mixing within a short time and improving the overall mixing effect.
[0027] 5. Spiral discharge port design: The spiral arrangement of the discharge ports, combined with the co-rotation of the mixing drum, avoids the situation where materials are discharged directly without being fully mixed, while maximizing the time that materials are blocked by the baffles, making it easier for technicians to perform relevant design calculations.
