[0028] 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.
[0029] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.
[0030] Reference Figure 1-3This utility model discloses a multi-layer temperature-controlled grain cooking device, comprising a cooking chamber 1. Multiple ventilation holes (not shown in the figure) are provided at the rear of the cooking chamber 1 to facilitate the release of gases such as water vapor and carbon dioxide generated during the cooking process, including moisture evaporation, starch gelatinization, protein denaturation, and decomposition of trace components. Two partitions 3 are fixedly connected inside the cooking chamber 1, dividing the interior into three independent cooking spaces. Storage boxes 4 are provided at the top of the partitions 3 and at the bottom of the cooking chamber 1. A removable baffle (not shown in the figure) is provided at the rear of each storage box 4, allowing for easy removal of the storage box 4. Two fixed posts 5 are fixedly connected to both sides of the inner wall of the cooking chamber 1, providing support. Sliding grooves 6 are provided on adjacent sides of the two fixed posts 5, with limit blocks (not shown in the figure) installed on both sides of the sliding grooves 6 to prevent the flipping plate 10 from colliding with the inner wall of the storage box 4. A movable plate 7 is slidably connected between two chute 6, serving a supporting function. A motor 8 is fixedly connected to the top of the movable plate 7, and a stirring rod 9 is fixedly connected to the output end of the motor 8 through the movable plate 7. A rotating rod 21 is rotatably connected to the bottom left side of the movable plate 7, which can drive the stirring rod 9 to rotate via the motor 8. Multiple flipping plates 10 are fixedly connected to the lower outer ring of both the rotating rod 21 and the stirring rod 9. The rotation of the flipping plates 10 can turn the grains in the storage box 4, ensuring even heating. A gear 11 is fixedly connected to the upper outer ring of the stirring rod 9. Three electric heating plates 15 are fixedly connected to both sides of the inner wall of the maturation box 1, which can heat the grains to make them mature. A temperature sensor 18 is fixedly connected inside the storage box 4, which can detect the temperature of the grains. A display screen 19 is fixedly connected to the outside of the maturation box 1, which can display the temperatures of the grains in the multiple storage boxes 4.
[0031] Reference Figure 1-3A rack 12 is fixedly connected to the bottom of the right-side fixed column 5, and the rack 12 meshes with the gear 11, serving as a transmission mechanism so that the gear 11 can move along the rack 12 when it rotates. A sprocket 13 is fixedly connected to the upper outer ring of both the rotating rod 21 and the stirring rod 9. A chain 14 is provided on the outer ring of each sprocket 13, and the chain 14 meshes with the sprocket 13, serving as a transmission mechanism so that the stirring rod 9 can rotate while also driving the rotating rod 21. An electric heating plate 15 is located below the fixed column 5, and can be used to cook the corresponding space. Hot air blowers 16 are fixedly connected to the upper part of the cooking chamber 1 and the bottom of the two partitions 3. The hot air blowers 16 can convert the heat generated by the electric heating plate 15 into circulating hot air, which is evenly distributed to each layer through convection. A protective cover 17 is fitted over the motor 8, and the bottom of the protective cover 17 is fixedly connected to the moving plate 7, serving to protect the internal motor 8. Below the display screen 19 is a control panel 20, which is fixedly connected to the curing chamber 1. The heating power of each layer can be set independently through the control panel 20 to achieve precise temperature control of different areas (e.g., 70℃ for the upper layer, 80℃ for the middle layer, and 90℃ for the lower layer). Three chamber doors 2 are rotatably connected to the front of the curing chamber 1.
[0032] The working principle of this utility model is as follows: During operation, the grains to be cooked are placed into the corresponding storage boxes 4 according to their degree of cooking. The box door 2 is then closed. The electric heating plate 15 is then activated to heat the grains in the storage boxes 4. At the same time, the hot air blower 16 is activated to convert the heat generated by the electric heating plate 15 into circulating hot air, which is evenly distributed to each layer through convection. The hot air flows through the gaps between the grain particles, compensating for local temperature differences in the electric heating plate 15 and ensuring temperature uniformity within the same layer. Simultaneously, the motor 8 is activated. The motor 8 is installed on the top of the moving plate 7 and drives the stirring rod 9 to rotate. The flipping plate 10 below its outer ring stirs the grains. At the same time, the gear 11 above the stirring rod 9 meshes with the rack 12 at the bottom of the right fixed column 5. When the stirring rod 9 rotates, the rack 12 remains stationary, and the gear 11 moves along the rack 12, causing the moving plate 7 to slide left and right in the slide groove 6, so that the stirring rod 9 achieves a compound motion of "rotation + translation". In addition, the rotating rod 21 and the stirring rod 9 are linked by the sprocket 13 and the chain 14 to achieve simultaneous rotation. The heat causes the flipping plate 10 outside the rotating rod 21 to rotate, ensuring that the grain particles are fully turned over in the three-layer space and that the grains are heated evenly.
