[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] like Figure 1-4As shown, this embodiment includes a housing 10, with an air inlet 11 on one side and an air outlet 12 on the top; thus, during the baking process of the baking machine, smoke enters from the air inlet 11, is removed by the smoke remover of this application, and is then discharged through the air outlet 12.

[0025] The bottom of the housing 10 is provided with support feet 13, which are evenly distributed at the four corners of the bottom of the housing 10, so that the housing 10 is stably supported on the ground or other load-bearing surfaces, thereby preventing the equipment from shaking or shifting during operation.

[0026] Because smoke is not produced throughout the entire coffee roasting process, there is no smoke at the initial low temperature. Smoke gradually appears as the temperature rises above the smoke point, and the amount of smoke increases as the temperature rises. At the end of roasting, the material is discharged to the cooling tray, at which point the cooling exhaust pipe will have a large amount of smoke for a short period of time. Subsequently, when the material cools down to a certain degree, no more smoke is produced.

[0027] Therefore, the air inlet 11 is connected to a connecting member 16. In this embodiment, the connecting member 16 is a three-way pipe. The first end of the three-way pipe is connected to the air inlet 11, the second end is connected to the smoke source of the baking machine, and the third end is connected to the cooling exhaust pipe. By setting the connecting member 16, the smoke source can be flexibly switched or expanded, thereby meeting the smoke treatment needs under different working conditions.

[0028] A cooling fan 14 is provided at the bottom inside the housing 10. The air outlet of the cooling fan 14 is connected to the outside. During the operation of the equipment, the cooling fan 14 can effectively reduce the temperature inside the housing 10, avoid the aging or failure of components due to excessive internal temperature, and thus improve the stability and service life of the equipment.

[0029] The housing 10 has a first cavity 20 communicating with the air inlet 11 and a second cavity 30 communicating with the first cavity 20. The top of the second cavity 30 is communicating with the air outlet 12. The first cavity 20 has a fan 21, and the air outlet of the fan 21 is communicating with the second cavity 30. Thus, the fan 21 is used to draw smoke from the air inlet 11 and pass it through the first cavity 20, the second cavity 30, and the air outlet 12 in sequence, and finally discharge it to the outside from the air outlet 12.

[0030] The first cavity 20 is also equipped with a filter screen 22. The filter screen 22 is located at the front end of the air inlet of the fan 21, that is, the filter screen 22 is located in the first cavity 20 and close to the air inlet 11. The filter screen 22 performs preliminary filtration of particulate matter in the smoke, thereby reducing the subsequent processing load and improving the overall purification efficiency.

[0031] In this embodiment, the filter screen 22 is detachably installed inside the first cavity 20, which facilitates regular cleaning or replacement and ensures long-term stable operation of the equipment.

[0032] The second chamber 30 is provided with a heater 31 and a catalyst layer 32 from bottom to top. The operation of the fan 21 can draw smoke from the air inlet 11 and pass through the first chamber 20 and the second chamber 30 in sequence. The smoke is heated by the heater 31 and then undergoes a catalytic reaction through the catalyst layer 32. The gas after the catalytic reaction is discharged through the air outlet 12, thereby achieving efficient decomposition and purification of harmful gases in the smoke and ensuring that the emitted gas meets environmental protection standards.

[0033] The heater 31 is used to heat the smoke to the reaction temperature required by the catalyst layer 32, so that the harmful gases in the smoke undergo a highly efficient catalytic oxidation reaction under the action of the catalyst layer 32 and decompose into harmless gases.

[0034] The first cavity 20 is provided with a first temperature sensor 23 for detecting the temperature inside the first cavity 20. The first temperature sensor is used to monitor the temperature change inside the first cavity 20 in real time.

[0035] A second temperature sensor 33 is provided between the heater 31 and the catalyst layer 32. The second temperature sensor 33 is used to monitor the temperature change in the second chamber 30 in real time to ensure that the catalyst layer 32 works within a suitable temperature range and avoids excessively high or low temperatures from affecting the purification effect or equipment safety.

[0036] High-temperature incineration methods result in excessive energy consumption and waste.

[0037] The housing 10 contains a control module 40, which is electrically connected to the fan 21, heater 31, first temperature sensor 23, second temperature sensor 33, and cooling fan 14. The control module 40 controls the operation of the fan 21, heater 31, and cooling fan 14 based on the detection signals from the first temperature sensor 23 and the second temperature sensor 33, thereby achieving precise control of the internal temperature of the equipment, ensuring the stability and efficiency of the entire purification process, and saving energy.

[0038] When the first temperature sensor 23 or the second temperature sensor 33 detects an abnormal temperature, the control module 40 can automatically adjust the working status of the fan 21, heater 31 or cooling fan 14 to respond to temperature changes in a timely manner, prevent equipment failure or reduction in purification efficiency caused by temperature fluctuations, and ensure continuous and safe operation of the equipment.

[0039] A control panel 15 is mounted on the exterior of the housing 10. The control panel 15 is electrically connected to the control module 40. The control panel 15 has a touch operation area for receiving user operation commands and transmitting them to the control module 40. The control module 40 adjusts the equipment operating mode according to the received operation commands to achieve intelligent management of the purification process. Users can set the target temperature, start / stop the equipment, or check the operating status through the touch operation area.

[0040] Therefore, this invention reduces the oxidation temperature of smoke to about 200 degrees Celsius by introducing a catalyst, which greatly reduces energy consumption compared to the 600-800 degrees Celsius required for traditional high-temperature incineration.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
