Description

Technical Field

[0001] The utility model relates to a stirring structure of a coffee bean roaster. Background Art

[0002] A coffee bean roaster is a device for roasting coffee beans. The coffee bean roaster mainly roasts coffee beans by rotating a drum, so it is necessary to configure a motor with a relatively large power to drive the drum. Generally, the roasting work of coffee beans lasts for a long time. In this case, driving the drum to work consumes a large amount of electric energy, and when the heat dissipation is poor or the weather is hot, the motor is prone to burnout.

[0003] Therefore, it is necessary to make further improvements to it. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above problems, and provides a stirring structure of a coffee bean roaster. This stirring structure does not require a high-power motor to drive, and has the advantages of energy saving and power saving.

[0005] To achieve the above purpose, the utility model provides a stirring structure of a coffee bean roaster, which includes a roasting barrel, a stirring paddle, a driving motor and a heating element arranged inside the machine body. The stirring paddle is arranged inside the roasting barrel for stirring coffee beans. The stirring paddle includes a rotating shaft, a first paddle blade and a second paddle blade circumferentially distributed on the rotating shaft. The front end of the rotating shaft is rotatably connected to the machine body, and the rear end of the rotating shaft is rotatably connected to the roasting barrel. The driving motor is connected to the rotating shaft to drive it to rotate. The first paddle blade is arranged obliquely from left to right, and the second paddle blade is arranged obliquely from right to left.

[0006] In one or more embodiments, bearing parts connected to the rotating shaft are arranged at the front end of the machine body and the rear end of the roasting barrel.

[0007] In one or more embodiments, the driving motor is fixed to the back of the roasting barrel through a bracket, and the rear end of the rotating shaft passes through the roasting barrel and is connected to the rotating shaft of the driving motor.

[0008] In one or more embodiments, the stirring paddle further includes a third paddle blade, and the structure of the third paddle blade is the same as that of the second paddle blade. The first paddle blade, the second paddle blade and the third paddle blade are circumferentially and evenly distributed on the rotating shaft.

[0009] In one or more embodiments, a door body is arranged at the front end of the machine body, a material guiding shell is arranged above the door body, the material guiding shell is communicated with the inside of the roasting barrel, and a gate for cutting off the connection between the material guiding shell and the inside of the roasting barrel is arranged on the material guiding shell.

[0010] In one or more embodiments, a heat insulation area is formed between the machine body and the roasting barrel. A heat dissipation port is arranged on the machine body, the heat dissipation port is communicated with the heat insulation area and the outside, and a fan is arranged on the heat dissipation port.

[0011] The effects of the present utility model compared with the background technology are as follows: The driving motor is used to drive the stirring paddle to rotate for stirring coffee beans. Therefore, a driving motor with a relatively small power can be selected, achieving the advantages of energy conservation and consumption reduction. In addition, by setting the opposite stirring angles of the first paddle and the second paddle on the stirring paddle, the coffee beans can be turned more evenly. Description of the Drawings

[0013] Figure 2 It is a schematic structural view of the stirring paddle according to the embodiment of the present utility model. Detailed Embodiment

[0014] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in combination with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not limit the protection scope of the present utility model.

[0015] Please refer to the attached Figure 1-2 This application provides a stirring structure for a coffee bean roasting machine, which includes a roasting barrel 2, a stirring paddle, a driving motor 3 and a heating element arranged inside the machine body 1. The stirring paddle is arranged inside the roasting barrel 2 for stirring coffee beans. The stirring paddle includes a rotating shaft 4 and a first paddle 5 and a second paddle 6 circumferentially distributed on the rotating shaft. The front end of the rotating shaft is rotatably connected to the machine body 1, and the rear end of the rotating shaft is rotatably connected to the roasting barrel 2. The driving motor 3 is connected to the rotating shaft to drive its rotation. By directly driving the stirring paddle by the driving motor, the coffee beans in the roasting barrel can be stirred, so that the coffee beans can be evenly heated. The first paddle 5 is arranged obliquely from left to right, and the second paddle 6 is arranged obliquely from right to left, that is, the setting angles of the first paddle and the second paddle are opposite, which is beneficial to stirring the coffee beans more evenly and uniformly roasting the coffee beans.

[0016] Bearing parts connected to the rotating shaft 4 are provided at the front end of the machine body 1 and the rear end of the roasting barrel. The setting of the bearing parts can ensure that the rotating shaft does not shake when rotating and rotates more smoothly.

[0017] The driving motor 3 is fixed to the back of the roasting barrel 2 through a bracket. The rear end of the rotating shaft passes through the roasting barrel and is connected to the rotating shaft of the driving motor 3. Direct connection between the driving motor and the rotating shaft can save the setting of the transmission structure and simplify the overall structure of the roasting machine.

[0018] The stirring paddle further includes a third paddle 7, and the structure of the third paddle is the same as that of the second paddle 6. The first paddle, the second paddle and the third paddle are circumferentially and evenly distributed on the rotating shaft. The setting of three paddles can better turn the coffee beans and make them evenly heated and roasted.

[0019] A door body 8 is provided at the front end of the machine body 1. Above the door body, there is a material guiding shell 9 which is internally connected to the baking barrel. A gate 10 for cutting off the connection between the material guiding shell and the interior of the baking barrel is provided on the material guiding shell. After the user pulls up the gate, coffee beans are poured into the material guiding shell, and the coffee beans enter the baking barrel for baking.

[0020] An insulation area 11 is formed between the machine body 1 and the baking barrel 2. There is a heat dissipation port on the machine body. The heat dissipation port communicates the insulation area with the outside. A fan 12 is provided on the heat dissipation port. The insulation area can reduce the temperature of the machine body to avoid scalding the user due to overheating. The setting of the fan can accelerate the discharge of the heat in the insulation area to avoid heat accumulation.

[0021] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present invention shall be included in the protection scope recorded in the claims.
