A heat dissipation member is installed on one side of the inside of the pressure chamber 7 close to the air inlet 11. A lifting device 10 is provided on the top of the pressure chamber 7. The top of the lifting device 10 is provided with a first air duct 2. One side of the lifting device 10 is detachably connected to a transparent baking chamber 3. The transparent baking chamber 3 is respectively communicated with the pressure chamber 7 and the first air duct 2. A collection bucket 8 is provided on one side of the lifting device 10 away from the transparent baking chamber 3. The collection bucket 8 is communicated with the first air duct 2. An exhaust port 9 is provided at the top of the first air duct 2 close to the collection bucket 8.

[0024] External cold air enters the pressure chamber 7 through the heat dissipation member via the air inlet 11. After being heated in the pressure chamber 7, the hot air enters the transparent baking chamber 3 to bake the coffee beans in the transparent baking chamber 3, and can optimize the uniformity of heat absorption when the coffee beans are heated. The silver skin enters the collection bucket 8 through the first air duct 2 for collection.

[0025] In a further optimized solution, the bottom of the transparent baking chamber 3 extends into the pressure chamber 7 and is communicated with the pressure chamber 7. A hot air guiding chamber 17 is provided at the top of the pressure chamber 7 close to the transparent baking chamber 3. The hot air guiding chamber 17 is respectively communicated with the inside of the transparent baking chamber 3 and the pressure chamber 7. An concave air duct is provided outside the hot air guiding chamber 17. The concave air duct is respectively communicated with the hot air guiding chamber 17 and the inside of the pressure chamber 7.

[0026] In a further optimized solution, a heating chamber 16 is provided in the concave air duct, and the heating chamber 16 is located at the bottom of the hot air guiding chamber 17.

[0027] A further optimized solution is that the air pressure chamber 7 is hollow, the heat dissipation element is the fan 12, a power module 13 is fixedly connected to the top surface of the air pressure chamber 7 close to the fan 12, and a control module 14 is fixedly connected to the bottom surface of the air pressure chamber 7 away from the fan 12. The control module 14 is located at the bottom of the concave air duct, and the control module 14 is electrically connected to the fan 12, the power module 13 and the heating chamber 16 respectively.

[0028] To further optimize the solution, a conical silver skin separation tube 19 is fixedly connected to the collecting barrel 8, and the collecting barrel 8 is a transparent silver skin collecting barrel 8.

[0029] As a further optimized solution, an S-shaped air duct bin 18 is provided in the first air duct 2 , the first air duct 2 is an S-shaped air duct, and the S-shaped air duct bin 18 is communicated with the collecting barrel 8 and the transparent baking chamber 3 respectively.

[0030] As a further optimization solution, a start switch 5 and a fan switch 6 are respectively provided on the outside of the air pressure chamber 7 , and the start switch 5 and the fan switch 6 are respectively electrically connected to the control module 14 .

[0031] According to a further optimized solution, a lifting switch 1 is provided on the outer side of the lifting device 10 , and the lifting switch 1 is transmission-connected to the lifting device 10 .

[0032] In a further optimized solution, a baking chamber handle 4 is installed on the outside of the transparent baking chamber 3.

[0033] Press the start switch 5, the equipment starts preheating, and the fan 12 draws cold air into the air pressure chamber 7 to form air pressure. The cold air passes through the power module 13 and the heat dissipation module to take away the heat. The cold air then flows to the dedicated concave air duct 15, and then enters the heating chamber 16 from the bottom of the heating chamber 16. After being heated by the heating chamber 16, it is converted into hot air and sent to the hot air guide chamber 17 to rectify the wind direction. The rectified hot air then enters the transparent roasting chamber 3. The hot air from bottom to top is converted into two kinds of rolling and rotating wind forces, thereby driving the coffee beans in the roasting chamber to roll and rotate. The coffee beans roll and rotate evenly and directionally in the roasting chamber, so that the coffee beans are heated more evenly and achieve a better roasting effect.

[0034] Working principle:

[0035] When it works, connect the power supply, turn on the APP to connect the coffee roaster, send the roasting curve required, press the start switch 5, and the coffee roaster enters the preheating state of the set curve. When the coffee roaster reaches the preheating temperature, press the lifting switch 1, and the lifting device 10 raises the S-shaped air duct bin 18. Take out the transparent roasting bin and add coffee beans. Then press the S-shaped air duct bin 18, lock the lifting device 10 by the lifting switch 1, touch the start switch 5, and the heating starts. The blower 12 sucks cold air from the air inlet 11 into the air pressure bin. On the way, it flows through the power supply module 13 and the control module 14 to suck away the heat of the modules. Then it enters the concave air duct 15 from the upper left of the air pressure bin. The concave air duct 15 takes away the external heat radiation heat of the heating chamber 16. It enters the heating chamber 16 from the bottom of the heating chamber 16 built inside the concave air duct 15 to heat the air. The hot air enters the hot air guiding chamber 17 from above the heating chamber 16 and then enters the transparent roasting chamber 3, so as to drive the green coffee beans to be evenly heated in two ways of suspension tumbling and rotation. The coffee beans release silver skins when heated. The silver skins rise from the transparent roasting chamber 3 to the S-shaped air duct bin 18, are converted into power by the S-shaped air duct bin 18, flow to the conical silver skin separation pipe 19 at the lower right, and the conical silver skin separation pipe 19 pneumatically settles the silver skins into the collection bucket 8. The hot air is discharged from the exhaust port 9 at the upper right of the S-shaped air duct bin 18 until the heating process ends and enters the cooling stage. After the roasting is completed, press the lifting switch 1 to raise the S-shaped air duct bin 18, take out the transparent roasting chamber 3, and pour out the roasted coffee beans. The roasting process ends.
