[0062] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0063] Working principle: manually control the heating plate 3 to preheat the roasting box 2, compare the preheating data, and obtain the preheating temperature suitable for roasting coffee beans, wherein the preheating temperature is the starting point of the coffee bean roasting curve. After the coffee beans are introduced into the roasting box 2 to absorb heat, the temperature in the roasting box 2 will decrease, and the temperature of the re-temperature point of the coffee beans is obtained, wherein the re-temperature point temperature is the lowest point of the coffee bean roasting curve, and then the heating plate 3 is controlled to start, the temperature inside the roasting box 2 is raised, and the temperature of the first bursting point of the coffee beans is obtained. Subsequently, the temperature inside the roasting box 2 is controlled to continue to rise, and the temperature of the second bursting point of the coffee beans is obtained. In summary, the preheating temperature, the re-temperature point temperature, the first bursting point temperature and the second bursting point temperature are connected in sequence, which is the coffee bean roasting curve;

[0064] The coffee bean roasting curve is programmed and imported into the operation panel 53. Subsequently, the heating plate 3 is started through the operation panel 53 to heat the inside of the roasting box 2 to the preheating temperature. The air pressure in the roasting box 2 can be detected in real time through the wind pressure sensor 8. When the air pressure in the roasting box 2 is not suitable for roasting coffee beans, the vertical fan 6 is started to introduce airflow into the roasting box 2 in cooperation with the pressure control cylinder 4 and the pressure control pipeline 5, so as to adjust the gas pressure in the roasting box 2.

[0065] When the interior of the roasting box 2 reaches the preheating temperature, the operation panel 53 controls the blocking motor 44 to start, and cooperates with the connection between the blocking motor 44 and the blocking shaft 42 to drive the blocking sheet 43 to flip through the blocking shaft 42, so that the coffee beans can enter the roasting box 2 through the feeding pipe 41. When the temperature in the roasting box 2 is absorbed by the coffee beans to the temperature of the return point, the operation panel 53 controls the heating plate 3 to start, and the temperature inside the roasting box 2 is increased according to the roasting curve of the coffee beans;

[0066] At the same time, the transmission motor 10 is started to drive the central shaft 9 to rotate, and the threaded section 12 is set so that the threaded section 12 can drive the linkage shaft 14 to rotate on the displacement frame 13, prompting the linkage bevel gear A15 to shift the linkage bevel gear B17, and then drive the stirring roller 18 to rotate, so as to turn the coffee beans, so that the coffee beans can be heated evenly, and the hydraulic cylinder 23 can be started to push the guide frame 24 to move upward. Since the guide frame 24 is in contact with the pressure plate 21, when the guide frame 24 moves upward, the extrusion slope can be used to push the pressure slope, so that the positioning shaft 20 is close to the linkage shaft 14, until the positioning shaft 20 is stuck in the linkage shaft 14, so that the linkage shaft 14 is free The method is to rotate on the displacement frame 13, and then the transmission motor 10 is started to drive the threaded section 12 to rotate, and the threaded section 12 and the displacement frame 13 are connected. Since the displacement frame 13 is limited on the displacement frame 13 by the positioning shaft 20, when the threaded section 12 rotates, the linkage shaft 14 can be driven to move along the threaded section 12, so as to change the position of the stirring roller 18 inside the roasting box 2, so as to realize the turning of coffee beans at different positions. When the pressure plate 21 is displaced, the coil spring 22 can be deformed at the same time. When the guide frame 24 is away from the pressure plate 21, the pressure plate 21 can be pushed by the coil spring 22, so that the positioning shaft 20 is separated from the linkage shaft 14.

[0067] When the temperature in the baking box 2 approaches the first bursting point, smoke will be generated inside the baking box 2. At this time, the operation panel 53 controls the electric push rod 29 to start, and pushes the blocking plate 28 to flip under the support of the support shaft 27, so as to release the blockage of the top of the smoke exhaust pipe 25. At the same time, during the flipping process of the blocking plate 28, the guide plate B40 can be pulled at the same time, so that the guide plate B40 drives the guide plate A39 to rotate, and under the cooperation of the guide plate A39 and the linkage groove 37, the linkage groove 37 can be pushed by the guide plate A39, so that the linkage frame 35 drives the displacement slide rod 33 to move out of the smoke exhaust shaft rod 31, until the acceleration bevel gear 34 is meshed with the transmission bevel gear 11, and then during the rotation of the central shaft rod 9, the acceleration bevel gear 34 can be dialed through the transmission bevel gear 11, so that the smoke exhaust shaft rod 31 drives the smoke exhaust plate 32 to rotate, so as to discharge the smoke in the baking box 2.

[0068] After the subsequent coffee beans are roasted, the hydraulic rod 49 is started to pull the assembly frame 50 to move downward, and the eccentric plate 51 can be pulled synchronously with the connection between the assembly frame 50 and the guide groove 52. Since the eccentric plate 51 is supported by the discharge shaft 46, the discharge shaft 46 can drive the blocking plate 47 to flip, thereby releasing the blockage of the roasting box 2, so that the coffee beans in the roasting box 2 can be discharged, and the transmission motor 10 can be started to adjust the stirring roller 18 to be perpendicular to the length direction of the heating plate 3, and then the stirring roller 18 is limited by the positioning shaft 20, and the stirring roller 18 is displaced inside the roasting box 2 by the rotation of the threaded section 12, so that the coffee beans are pushed out of the roasting box 2.
