[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 5 As shown, an intelligent coffee bean roasting device includes an equipment body 1, a flue 4 connected to the back of the equipment body 1, an electric heating coil 5 connected to the inner side wall of the equipment body 1, and an anti-scalding grille 6 below the electric heating coil 5. The equipment body 1 consists of a roasting chamber 10), a fan chamber 7 and a motor chamber 8. The fan chamber 7 is provided with a fan, the motor chamber 8 is provided with a driving motor, the roasting chamber 10 is provided with a rotating component 9, the roasting chamber 10 is provided with a roasting bean box 2, the front of the roasting chamber 10 is buckled with one end of the roasting bean box 2, and the roasting chamber 10 is provided with a silver skin tray 3, and the front of the roasting chamber 10 is buckled with one end of the silver skin tray 3.

[0024] like Figure 1 As shown, the structure of an intelligent coffee bean roasting device in the utility model is similar to that of an existing coffee bean roasting device, such as the intelligent coffee bean roasting device disclosed in the patent with publication number CN205695563U. The main improvement of the utility model is that the silver skin and debris generated by drying of the coffee beans during roasting are separated from the coffee beans, and the coffee beans are heated evenly. Figures 1 to 5As shown, when an intelligent coffee bean roasting device in the utility model is in use, the electric heating coil 5 inside the equipment body 1 generates heat, and the fan generates wind force, so that the heat inside the roasting chamber 10 starts to circulate, and the coffee beans are in a high temperature environment. The rotating component 9 rotates through the driving motor to turn the coffee beans in the roasting bean box 2. Through the cooperation of the electric heating coil 5 and the rotating component 9, the coffee beans are evenly roasted, and the wind force of the fan blows the silver skin and debris on the surface of the coffee beans into the silver skin tray 3 under the equipment body 1. When the roasting is finished, the operator can directly take out the evenly roasted coffee bean products, and the silver skin and debris in the silver skin tray 3 can be directly processed. The smoke generated during roasting is transmitted through the flue 4. An anti-scalding grille 6 is provided inside the equipment body 1 to prevent the operator from being scalded by the electric heating coil 5. Through this setting, the silver skin and finished coffee beans are separated, the working steps of the operator are simplified, and the automation and convenience of the equipment are improved.

[0025] like Figure 4 As shown, the rotating assembly 9 includes a plurality of sliding plates 901 and a rotating shaft 902. The outer side of the rotating shaft 902 is fixedly connected to the sliding plate 901. The plurality of sliding plates 901 are staggered and arranged at equal intervals. Circular holes 102 rotatably connected to the rotating shaft 902 are provided on both side walls of the baking chamber 10. One end of the rotating shaft 902 is fixedly connected to the output end of the driving motor.

[0026] Specifically, a rolling bearing is provided in the circular hole 102, and the outer ring of the rolling bearing is fixedly connected to the circular hole 102, and the inner ring of the rolling bearing is rotatably connected to the rotating shaft 902. The rotating shaft 902 drives the sliding plate 901 to rotate, and the offset gaps between the plurality of sliding plates 901 can allow the coffee beans lifted by the rotation to slide back into the roasting bean box 2, so that the coffee beans are cyclically turned over in the roasting bean box 2 and are evenly heated. The movement of the coffee beans separates the dry silver skin from the coffee beans, and the operator can obtain a complete coffee product without debris after the roasting is completed, which reduces the operator's operation process of cleaning the silver skin and improves the functionality and convenience of the equipment.

[0027] like Figures 2 to 5 As shown, the bean roasting box 2 includes a bean roasting basket 201, a connecting plate 202, a baffle 203 and a handle 204. The back of the baffle 203 is fixedly connected to the inner side of the connecting plate 202, the connecting plate 202 is fixedly connected to the outer side of the bean roasting basket 201, the outer side of the baffle 203 is fixedly connected to the handle 204, and the front side of the roasting chamber 10 is provided with a withdrawal channel 105 buckled with the baffle 203, and the inner side of the withdrawal channel 105 is fixedly connected to the limiting frame 104.

[0028] Specifically, through the cooperation of the limiting frame 104 and the outer wall of the extraction channel 105, the baffle 203 can be buckled with the equipment body 1, and a connecting plate 202 is provided between the bean roasting basket 201 and the baffle 203, so that the position of the bean roasting basket 201 can be fitted with the position of the rotating component 9, and placed at the lower end of the electric heating ring 5, and the coffee beans are roasted. It is worth noting here that the material of the bean roasting basket 201 is a high-temperature heat-resistant metal material, so that the coffee beans in the bean roasting basket 201 can be heated. The operator pulls the handle 204 to drive the roasting bean box 2 as a whole to be put in or taken out of the roasting chamber 10. Through this arrangement, the coffee beans are evenly heated in the roasting bean box 2, which increases the practicality of the equipment.

[0029] like Figures 3 to 5 As shown, when the front side of the roasting chamber 10 is buckled with one end of the bean roasting box 2, the inner wall of the bean roasting basket 201 is slidably connected with the sliding plate 901, and the length of the sliding plate 901 is consistent with the diameter of the inner wall of the bean roasting basket 201.

[0030] Specifically, through this arrangement, when the sliding plate 901 rotates, the side of the sliding plate 901 fits against the inner wall of the roasting bean basket 201, driving the coffee beans to flip over in the roasting bean basket 201. Through the cooperation between the roasting bean basket 201 and the sliding plate 901, the coffee beans can keep rotating consistently in the roasting chamber 10, thereby increasing the functionality of the equipment.

[0031] like Figures 3 to 5 As shown, the silver drawer 3 includes a crumb basket 301, a partition 302 and a handle 303. The inner side of the partition 302 is fixedly connected to one side of the crumb basket 301, and the outer side of the partition 302 is fixedly connected to the handle 303. A drawer opening 106 that is buckled with the partition 302 is opened on the front of the baking chamber 10.

[0032] Specifically, through this arrangement, when the operator pulls the handle 303, the entire silver tray 3 is taken out of or put into the baking chamber 10, thereby increasing the functionality of the device.

[0033] like Figure 1 As shown, an exhaust hole 101 matching the flue 4 is opened on the inner wall of the baking chamber 10 , and the exhaust hole 101 is connected to the flue 4 .

[0034] Specifically, through this arrangement, during the operation of the equipment, a large amount of smoke will be generated due to the high-temperature roasting of coffee beans. The smoke will adhere to the surface of the coffee beans. Through the cooperation of the exhaust hole 101 and the flue 4, a large amount of smoke will be discharged from the flue 4, thereby improving the quality of the coffee beans and increasing the functionality of the equipment.

[0035] like Figure 1 As shown, the inner wall of the baking chamber 10 is provided with air supply holes 103 corresponding to the positions of the fans.

[0036] Specifically, when the fan rotates, wind is sent into the baking chamber 10 through the air supply holes 103. The air supply holes 103 can reduce the heat received by the fan, increase the service life of the equipment, reduce the maintenance work of the operator, and improve the stability of the equipment.

[0037] like Figure 2 As shown, a support frame 701 is fixedly connected to the inner wall of the fan chamber 7, and the other end of the support frame 701 is fixedly connected to the fan.

[0038] Specifically, by this arrangement, the fan is fixedly connected to the support frame 701, so that the fan is stably connected inside the device body 1, thereby increasing the stability of the device.

[0039] like Figure 2 As shown, a fixing bracket 801 is fixedly connected to the inner wall of the motor chamber 8, and the other end of the fixing bracket 801 is fixedly connected to the driving motor.

[0040] Specifically, by this arrangement, the driving motor is fixedly connected to the fixing bracket 801, so that the fan is stably connected inside the device body 1, thereby increasing the stability of the device.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
