[0026] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-5As shown, this utility model provides a seed roasting device with overheat protection function, including a seed roasting room 1, a control terminal 2, and a heating pipe 3. The seed roasting room 1 is provided with a roasting chamber 4 and a heating chamber 5. The roasting chamber 4 is provided with a conveying assembly 6. The heating pipe 3 includes a heating bypass pipe 7 and a heating supply pipe 8. The heating bypass pipe 7 is connected to the heating supply pipe 8. The heating bypass pipe 7 is placed inside the heating chamber 5. The heating supply pipe 8 is placed outside the seed roasting room 1. A shut-off valve 9 and a proportional valve 10 are connected in series in the heating supply pipe 8. A temperature sensor is provided in the roasting chamber 4. The temperature sensor, shut-off valve 9, and proportional valve 10 are electrically connected to the control terminal 2. By placing areca nuts onto the conveying assembly 6, the areca nuts are transported to the roasting chamber 4. High-temperature steam or hot water is then introduced into the heating pipe 3, and the areca nuts are continuously heated and roasted through heat radiation. The temperature of the roasting chamber 4 is monitored in real time by a temperature sensor, and the temperature data is transmitted to the control terminal 2. A maximum temperature threshold is preset in the control terminal 2. When the temperature data fed back by the temperature sensor exceeds the maximum temperature threshold, the control terminal 2 will control the shut-off valve 9 to close, cutting off the heat supply source of the heating bypass pipe 7, and at the same time, an alarm will be issued. Alternatively, the opening of the proportional valve 10 can be adjusted manually by operating the control terminal 2 to adjust the heating curve in the roasting room 1.

[0028] like Figure 4 As shown, specifically, the heating chamber 5 is located above the baking chamber 4.

[0029] like Figure 5 As shown, alternatively, the heating chamber 5 is located on the outer layer of the baking chamber 4.

[0030] Specifically, a pressure sensor is installed below the conveying assembly 6, and the pressure sensor is electrically connected to the control terminal 2. When a new batch of areca nuts enters the conveying assembly 6, the pressure sensor continuously records the weight change of that batch of areca nuts and transmits the weight data to the control terminal 2. The control terminal 2 can generate a areca nut weight change curve based on this weight data, allowing staff to intuitively and quickly understand the state of the areca nuts.

[0031] Specifically, the conveying assembly 6 has a feeding bin 11 and a dropping hopper 12 at each end, both of which are located outside the roasting room 1. The processed areca nuts can be fed into the conveying assembly 6 manually or via a conveyor belt through the feeding bin 11. The dropping hopper 12 can also be replaced by a conveyor belt leading to the next process.

[0032] like Figure 3As shown, specifically, the feeding hopper 11 is equipped with a hinge plate 13 and a guide plate 14 that are movably arranged inside. A cylinder 15 is installed at the bottom of the hinge plate 13, and the hinge plate 13 moves with the cylinder 15. The guide plate 14 is located below the hinge plate 13 and is in an inclined position. The hinge plate 13 is movably mounted on the inner wall of the feeding hopper 11 via a rotating shaft, thereby realizing the function of opening and closing. When it is necessary to add areca nuts, the hinge plate 13 can block the feeding hopper 11 to ensure that they do not fall out prematurely. In order to drive the hinge plate 13, a cylinder 15 is also installed on the inner wall of the feeding hopper 11. The piston rod of the cylinder 15 is connected to the bottom of the hinge plate 13, and the extension and retraction of the cylinder 15 drives the hinge plate 13 to open and close. This not only realizes automated control, but also greatly improves the convenience and accuracy of operation.

[0033] In actual operation, after the operator puts the areca nuts to be roasted into the top of the feeding hopper 11, the areca nuts will first fall onto the hinge plate 13. The operator can put the areca nuts in batches through the hinge plate 13 to prevent the areca nuts from clogging the feeding hopper 11 or the conveying component 6, thus affecting production efficiency. When the areca nuts on the hinge plate 13 reach the amount that can be put in at once, the cylinder 15 is activated to drive the hinge plate 13 to move, so that the hinge plate 13 no longer blocks the feeding hopper 11, and the areca nuts fall downwards under the action of gravity. In order to ensure that the areca nuts fall neatly into the port of the conveying component 6, a guide plate 14 is also installed in the feeding hopper 11, which is located below the hinge plate 13. After being weighed, the areca nuts fall onto the conveying component 6 after passing through the guide plate 14. The guide plate 14 can guide the areca nuts to fall in an orderly manner, avoiding the areca nuts from being scattered or deviating during the fall, so that the areca nuts all fall into the port of the conveying component 6.

[0034] Furthermore, a weighing device can be installed on the hinge plate 13, and the weighing device, cylinder 15 and control terminal 2 can be electrically connected. A weight limit can be set on the control terminal 2. When the weight of the areca nuts on the hinge plate 13 reaches the limit weight, the control terminal 2 will automatically control the cylinder 15 to retract and open the hinge plate 13 to complete the automatic control.

[0035] In this embodiment, the conveying assembly 6 is a conveyor belt, which consists of a belt and pulleys. Inside the feeding hopper 11, an intervention wheel 16 that rotates together with the conveying assembly 6 is also provided, located below the guide plate 14. Specifically, the intervention wheel 16 consists of a rotating shaft and multiple intervention plates fixed to the rotating shaft. The rotating shaft of the intervention wheel 16 is connected to the pulleys of the conveyor belt via a belt drive assembly, allowing the intervention wheel 16 to rotate with the conveyor belt. After the areca nuts fall to the left end of the conveying assembly 6, they move from left to right to the position of the intervention wheel 16 as the conveying assembly 6 moves. As the areca nuts pass the intervention wheel 16, the rotation of the intervention wheel 16 agitates and spreads the areca nuts, ensuring they are evenly distributed on the conveyor belt, preventing accumulation and overlap, and ensuring that the areca nuts are heated evenly during the roasting process.

[0036] Preferably, the conveying component 6 is provided with multiple leveling baffles 18 above it, which can level the areca seeds during the conveying process, prevent the areca seeds from piling up, and make the areca seeds roast more evenly, thereby improving the roasting effect.

[0037] Preferably, the conveying assembly 6 has a transition chamber 17 at one end near the hopper 12. The bottom of the transition chamber 17 has a channel for the conveying device to pass through, and rubber baffles 20 are provided on both sides of the channel. The transition chamber 17 can reduce the loss of heat from the baking chamber 4 to the outlet of the conveying assembly 6 to a certain extent.

[0038] Preferably, a heat-insulating baffle 19 is also provided outside the seed drying room 1, and a heat-insulating cavity is provided between the heat-insulating baffle 19 and the seed drying room 1. This can effectively prevent burns to operators.

[0039] Working process and principle:

[0040] Areca nuts are fed into the feeding hopper 11 manually or directly via conveyor belt. The areca nuts are then fed onto the hinged plate 13 within the feeding hopper 11. When the weight of areca nuts on the hinged plate 13 reaches the limit for a single entry, the control terminal 2 automatically controls the hinged plate 13 to open. The areca nuts are guided by a guide plate and fall into the inlet of the conveying assembly 6. Then, the intervention wheel 16 flattens and spreads the areca nuts into the roasting chamber 4 in the roasting room 1. The conveying assembly 6 then stops operating, and high-temperature steam or hot water is continuously introduced into the heating bypass pipe 7, allowing the heating chamber 5 to continuously radiate heat to the roasting chamber 4, roasting the areca nuts. During this process, temperature and pressure sensors continuously monitor the temperature and weight of the areca nuts within the roasting chamber 4. This data is synchronously transmitted to the control terminal 2 and displayed on the control terminal. Terminal 2 generates temperature and weight curves, which allow staff to determine the roasting status of the areca nuts. The staff can then control the proportional valve 10 on the heating pipe 8 to regulate the temperature of the heating chamber 5, thereby regulating the temperature of the roasting chamber 4. Alternatively, the proportional valve 10 can be automatically regulated by the program within the control terminal 2. When the temperature in the roasting chamber 4 reaches the preset maximum temperature threshold, the control terminal 2 will close the shut-off valve 9 on the heating pipe 8, stopping the heating pipe 3 from supplying heat. The control terminal 2 will also issue an alarm to remind the staff. After the areca nuts have finished roasting, the conveying assembly 6 is restarted, sending the roasted areca nuts out of the roasting room 1 while simultaneously sending a new batch of areca nuts that need to undergo roasting into the roasting room 1.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
