[0001] This utility model belongs to the field of grain baking technology, specifically a tunnel-type hot air circulation grain baking equipment. Background Technology

[0002] The tunnel-type hot air circulation grain roasting equipment is designed for continuous, large-scale grain roasting and processing. It achieves efficient and uniform heating through a tunnel-type cavity and a forced hot air circulation system. It adopts a multi-layer mesh belt conveyor structure, combined with an axial fan and a guide device, to allow hot air to penetrate the grain layer to improve heat exchange efficiency. It is suitable for drying, roasting, and flavor shaping of products such as coffee beans, nuts, and grains.

[0003] In most existing grain roasting methods, the grains are placed inside a drum for roasting. However, this method lacks a turning device, which leads to uneven roasting and affects the yield of the finished grain. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a tunnel-type hot air circulation grain baking equipment, which solves the problem that in existing grain baking, the grain is mostly placed in a drum for baking. However, this baking method lacks a turning device, which leads to uneven baking during the grain baking process and affects the yield of the finished grain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel-type hot air circulation grain roasting equipment, including a roasting box, a sliding groove on one side of the roasting box, a locking slider slidably connected through the sliding groove, damping telescopic rods fixedly connected to the top and bottom of the locking slider, mounting grooves on the top and bottom walls of the sliding groove, one end of the damping telescopic rod fixedly connected to the inner wall of the mounting groove, a return spring sleeved on the outer arc surface of the damping telescopic rod inside the sliding groove, and a mounting box fixedly connected to one side of the locking slider. A rotary motor is fixedly connected inside the mounting box. A rotary gear is fixedly connected to the output end of the rotary motor. One end of the rotary gear is rotatably connected to one side of the locking slider via a bearing. A connecting gear meshes with the top of the rotary gear. One end of the connecting gear passes through the locking slider and is fixedly connected to a baking cylinder. The connecting gear is rotatably connected to the locking slider via a bearing. A rotating wheel is fixedly connected to the end of the baking cylinder away from the locking slider. Elastic fixing rods are symmetrically fixed to both sides of the rotating wheel. The end of the elastic fixing rod away from the rotating wheel is fixedly connected to the inner wall of the baking box.

[0006] As a further embodiment of this utility model: the outer arc surface of the baking cylinder is rotatably connected to a feed cover via a pin, and an elastic buckle is fixedly connected to one side of the feed cover, the elastic buckle being snapped onto the surface of the baking cylinder.

[0007] As a further embodiment of this utility model: the bottom of the baking box is rotatably connected to a discharge plate via a pin, and a pin is fixedly connected between the discharge plate and the baking box; the top of the baking box is rotatably connected to a feed plate via a pin, and the positions of the feed plate and the feed cover correspond to each other.

[0008] As a further embodiment of this utility model: the top and one side of the baking oven are respectively provided with ventilation holes, and a fixed frame is fixedly connected inside the ventilation holes.

[0009] As a further embodiment of this utility model: a fan motor is fixedly connected to one side of the fixing frame, an intake fan is fixedly connected to the output end of the fan motor located at the top of the baking oven, and an exhaust fan is fixedly connected to the output end of the fan motor located on one side of the baking oven.

[0010] As a further embodiment of this utility model: a heating tube mechanism is provided on the top wall of the baking oven at the position corresponding to the vent hole, and support legs are fixedly connected to the four corners of the bottom of the baking oven.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This tunnel-type hot air circulation grain roasting equipment, through the setting of a roasting cylinder, connecting gears, and locking sliders, can start a rotary motor to drive the rotating gears and connecting gears to rotate during heating and roasting. The connecting gears drive the roasting cylinder to rotate. When the roasting cylinder rotates, because there are grains inside, the center of gravity of the roasting cylinder becomes unstable. This causes the locking slider to slide up and down in the sliding groove, while squeezing the damping telescopic rod and the return spring. This creates a rotating oscillation of the roasting cylinder, turning the grains and making the grains roast more evenly.

[0013] This tunnel-type hot air circulation grain roasting equipment, equipped with a fan motor, heating element mechanism, and exhaust fan, allows for efficient grain roasting. When the grain needs to be roasted, the fan motor is activated to drive the intake fan to rotate, while the heating element mechanism is simultaneously activated. The intake fan blows air onto the heating element mechanism, directing hot air into the roasting drum. At the same time, the exhaust fan rotates to expel air from one side, thus creating a hot air circulation. This hot air circulation penetrates the grain layer, eliminating the temperature gradient that occurs during static roasting, preventing localized over-burning or under-roasting, and ensuring consistent color and flavor.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a tunnel-type hot air circulation grain baking equipment, including a baking box 1. A sliding groove 2 is provided on one side of the baking box 1. A snap-fit ​​slider 3 is slidably connected through the sliding groove 2. A damping telescopic rod 5 is fixedly connected to the top and bottom of the snap-fit ​​slider 3. An installation groove 4 is provided on the top and bottom walls of the sliding groove 2. One end of the damping telescopic rod 5 is fixedly connected to the inner wall of the installation groove 4. A return spring 6 is sleeved on the outer arc surface of the damping telescopic rod 5 inside the sliding groove 2. By setting the damping telescopic rod 5, whenever the return spring 6 is squeezed and reset, the damping telescopic rod 5 will extend and retract, thereby reducing the rebound potential energy of the return spring 6 after reset, thereby preventing the return spring 6 from always being in the rebound state.

[0020] A mounting box 7 is fixedly connected to one side of the snap-fit ​​slider 3. A rotary motor 8 is fixedly connected inside the mounting box 7. A rotary gear 9 is fixedly connected to the output end of the rotary motor 8. One end of the rotary gear 9 is rotatably connected to one side of the snap-fit ​​slider 3 through a bearing. A connecting gear 10 is meshed with the top of the rotary gear 9. One end of the connecting gear 10 passes through the snap-fit ​​slider 3 and is fixedly connected to the baking cylinder 11. The connecting gear 10 is rotatably connected to the snap-fit ​​slider 3 through a bearing. Through the setting of the connecting gear 10 and the rotary gear 9, the rotary motor 8 drives the rotary gear 9 to rotate, and then the rotary gear 9 synchronously drives the connecting gear 10 to rotate, so that the connecting gear 10 can drive the baking cylinder 11 to rotate, thereby causing the baking cylinder 11 to rotate and turn the grains.

[0021] A rotating wheel 14 is fixedly connected to the end of the baking cylinder 11 away from the locking slider 3. Elastic fixing rods 15 are symmetrically fixedly connected to both sides of the rotating wheel 14. The end of the elastic fixing rod 15 away from the rotating wheel 14 is fixedly connected to the inner wall of the baking box 1. By setting the elastic fixing rod 15, the rotating wheel 14 and the baking cylinder 11 are supported, preventing the baking cylinder 11 from tilting and collapsing because only one side of the baking cylinder 11 can be supported.

[0022] The outer arc surface of the baking cylinder 11 is rotatably connected to the feed cover 12 via a pin. One side of the feed cover 12 is fixedly connected to an elastic buckle 13. The elastic buckle 13 is snapped onto the surface of the baking cylinder 11. Through the setting of the feed cover 12 and the elastic buckle 13, the elastic buckle 13 is used to snap onto the surface of the baking cylinder 11, thereby preventing the feed cover 12 from suddenly opening when the baking cylinder 11 is rotated.

[0023] The bottom of the baking box 1 is rotatably connected to the discharge plate 16 via a pin. The discharge plate 16 is fixedly connected to the baking box 1 via a pin 17. The top of the baking box 1 is rotatably connected to the feed plate 19 via a pin. The feed plate 19 is positioned corresponding to the feed cover 12. With the setting of the pin 17, when it is necessary to open the discharge plate 16, the pin 17 can be pulled out so that the pin 17 no longer blocks the discharge plate 16, thereby allowing the discharge plate 16 to be rotated open.

[0024] The top and one side of the baking oven 1 are respectively provided with ventilation holes 20. A fixed frame 21 is fixedly connected inside the ventilation holes 20. A fan motor 22 is fixedly connected to one side of the fixed frame 21. An intake fan 23 is fixedly connected to the output end of the fan motor 22 located at the top of the baking oven 1, and an exhaust fan 24 is fixedly connected to the output end of the fan motor 22 located on the side of the baking oven 1. When the intake fan 23 and the exhaust fan 24 rotate simultaneously, air can be drawn into the baking oven 1 on one side and air can be drawn out of the baking oven 1 on the other side, thereby forming a wind circulation to assist baking.

[0025] A heating tube mechanism 25 is installed on the top wall of the baking oven 1 at the position corresponding to the vent 20. Support legs 18 are fixedly connected to the four corners of the bottom of the baking oven 1. Heating is carried out through the heating tube mechanism 25, so that the baking oven 1 can be heated and the grains inside the baking oven 1 can be baked.

[0026] The working principle of this utility model is as follows: First, open the feeding plate 19, then open the elastic buckle 13 and the feeding cover 12 to put the grains into the baking cylinder 11. After the grains are put in, they need to be baked. By starting the fan motor 22, the output end of the fan motor 22 drives the air intake fan 23 to rotate. At the same time, the heating tube mechanism 25 is started. The air intake fan 23 draws in outside air and blows it onto the heating tube mechanism 25, so that hot air can flow into the baking cylinder 11. At the same time, the exhaust fan 24 rotates to exhaust the air in the baking cylinder 11, thereby forming a hot air circulation to bake the grains. During heating and baking, the rotary motor 8 can be started to use the rotation... The output of the motor 8 drives the rotating gear 9 to rotate, and the rotating gear 9 drives the meshing connecting gear 10 to rotate. The rotating connecting gear 10 synchronously drives the baking cylinder 11 to rotate inside the baking box 1. At this time, because there are grains inside the baking cylinder 11, the center of gravity of the baking cylinder 11 will be unstable when it rotates and stirs, resulting in a certain amount of swaying. At this time, the baking cylinder 11 will synchronously drive the locking slider 3 to slide up and down in the sliding groove 2. While the locking slider 3 is sliding, it squeezes the damping telescopic rod 5 and the return spring 6. At the same time, the damping telescopic rod 5 and the return spring 6 extend and retract, so that the baking cylinder 11 can stir the grains.

[0027] In the description of this utility model, it should be noted that, 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 based on the specific circumstances.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
