[0002] The roasting of coffee beans is the process of transforming the internal components of coffee beans. During the roasting process of coffee beans, the transformation of the components is very complex. Only after roasting can the components that can release the aroma of coffee bean be produced.

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please refer to Figure 1-Figure 8The present invention provides a technical solution: a coffee bean roasting device with different flavor substances, comprising a base 1, a roasting chamber 4 is arranged above the base 1, two hydraulic rods 1 2 and two hydraulic rods 2 3 are fixedly installed on the top of the base 1 and are distributed in a rectangular shape, the piston rod tops of the two hydraulic rods 1 2 and the two hydraulic rods 2 3 are hinged to the bottom of the roasting chamber 4, the roasting chamber 4 is provided with a roasting barrel 5, the roasting barrel 5 passes through the inner wall of one side of the roasting chamber 4 and is fixedly connected to the roasting chamber 4, and the side of the roasting barrel 5 extending outside the roasting chamber 4 is open, a lower hopper 9 is fixedly installed on the side of the roasting chamber 4 close to the opening of the roasting barrel 5, the lower hopper 9 is located below the roasting barrel 5, a spreading and stirring component 8 is rotatably installed in the roasting barrel 5, the spreading and stirring component 8 is used to stir and spread the coffee beans in the roasting barrel 5, a heater 10 for heating the coffee beans in the roasting barrel 5 is fixedly installed on the inner wall of the bottom of the roasting chamber 4, a driving mechanism 6 for driving the spreading and stirring component 8 to rotate is arranged on one side of the roasting chamber 4, and the same feeding hopper 7 is fixedly installed on the roasting chamber 4 and the roasting barrel 5.

[0031] The evenly spreading and stirring component 8 includes two circular plates 81 rotatably installed in the baking barrel 5, and a plurality of through holes 801 are opened on the circular plates 81 and distributed in a circular array. Six sector plates 82 distributed in a circular array are slidably installed between the two circular plates 81. The evenly spreading and stirring component 8 also includes three pairs of sieve plates 83 distributed in a circular array, and the ends of the three pairs of sieve plates 83 close to each other are fixedly connected to the corresponding sector plates 82 respectively, and a channel 84 is formed between two adjacent sieve plates 83. The evenly spreading and stirring component 8 also includes three pairs of sieve plates 2 85 and sieve plates 3 86 distributed in a circular array, and a channel 2 87 is formed between the adjacent sieve plates 2 85 and sieve plates 3 86. The three pairs of sieve plates 1 83 and the three pairs of sieve plates 2 85 and sieve plates 3 86 are distributed in an interval manner.

[0032] An L-shaped plate 88 is fixedly installed on the side of the sieve plate three 86 away from the sieve plate two 85, and a scraper 89 is slidably installed between the L-shaped plate 88 and the sieve plate three 86. The side of the scraper 89 away from the center of the baking barrel 5 is slidably connected to the inner wall of the baking barrel 5, and a plurality of linearly distributed springs 810 are fixedly installed on the side of the scraper 89 close to the center of the baking barrel 5, and the ends of the plurality of springs 810 away from the scraper 89 are fixedly connected to the L-shaped plate 88.

[0033] Furthermore, as the sieve plate 3 86 moves toward or away from the center of the circle of the sector plate 82 , the cooperation of the plurality of springs 810 can ensure that the scraper 89 can always be in close contact with the inner wall of the baking barrel 5 .

[0034] Two limit blocks 812 are fixedly installed on the side of the fan-shaped plate 82, and six limit grooves 811 distributed in a circular array are opened on the side where the two circular plates 81 are close to each other. The six limit grooves 811 are all located on the diameter line of the circular plate 81, and the multiple limit blocks 812 on the six fan-shaped plates 82 are respectively slidably installed in the corresponding limit grooves 811.

[0035] Furthermore, through the cooperation between the limiting groove 811 and the limiting block 812 , it can be ensured that the moving path of the sector plate 82 can coincide with the diameter line of the circular plate 81 .

[0036] An annular plate 817 is rotatably installed on the side where the two circular plates 81 are close to each other. The annular plate 817 is provided with six arc holes 818 distributed in a circular array. Rollers 816 are rotatably installed in the six arc holes 818. Connecting rods 815 are rotatably sleeved on the six rollers 816. The ends of the six connecting rods 815 that are away from each other are fixedly connected to the corresponding fan-shaped plates 82 respectively.

[0037] A wheel frame 821 is fixedly installed on the side of the two circular plates 81 that are away from each other. A worm 823 is rotatably installed through the wheel frame 821 and is fixedly connected to a second motor 822. The output shaft of the second motor 822 is fixedly connected to one end of the worm 823. A gear ring 820 is meshingly connected to the worm 823. A cylinder 819 is rotatably installed through the two circular plates 81. The two gear rings 820 and the two annular plates 817 are fixedly mounted on the corresponding cylinders 819 respectively.

[0038] Furthermore, by starting the second motor 822 to drive the worm 823 to rotate, the worm 823 can drive the cylinder 819 to rotate through the meshing gear ring 820, and the cylinder 819 can drive the annular plate 817 to rotate;

[0039] There will be differences in the size of coffee beans with different flavors, such as Figure 4 and Figure 5 As shown, when the annular plate 817 rotates counterclockwise, the multiple rollers 816 are driven to approach each other through the multiple arc holes 818, and the multiple rollers 816 then drive the multiple fan-shaped plates 82 to approach each other through the corresponding connecting rods 815. In the process of the multiple fan-shaped plates 82 approaching each other, as the sieve plates 2 85 and sieve plates 3 86 constituting the channel 2 87 approach each other, the channel 2 87 will become narrower. In addition, as the two sieve plates 1 83 constituting the channel 1 84 approach each other, the channel 1 84 will also become narrower. By controlling the rotation direction of the annular plate 817, the widths of the channel 1 84 and the channel 2 87 can be adjusted. Therefore, when spreading coffee beans of different particle sizes, the accumulation of coffee beans can be effectively prevented.

[0040] A circular hole 51 is formed on the side of the baking barrel 5 away from the opening. The driving mechanism 6 includes a frame 63 that penetrates the circular hole 51 and is fixedly connected to the corresponding circular plate 81, and a motor 61 fixed to one side of the baking chamber 4. A transmission shaft 64 is fixedly connected to the frame 63. The transmission shaft 64 penetrates the baking chamber 4 and is rotatably connected to the baking chamber 4. A fixed sleeve of the portion of the transmission shaft 64 located outside the baking chamber 4 is provided with a pulley 2 65. A pulley 1 62 is fixedly installed on the output shaft of the motor 1 61. The pulley 1 62 and the pulley 2 65 are sleeved with the same synchronous belt.

[0041] An L-shaped arc plate 813 is fixedly installed on the inner walls of the three sector plates 82 to which the sieve plate 2 85 is fixed, and a channel 3 814 is formed between the L-shaped arc plate 813 and the adjacent sector plate 82 to which the sieve plate 3 86 is fixed.

[0042] The process for roasting green coffee beans with different flavor substances is applicable to the above-mentioned green coffee bean roasting equipment with different flavor substances, and comprises the following steps:

[0043] S1, the green coffee beans enter the roasting barrel 5 through the hopper 7, and the heater 10 generates heat and roasts the green coffee beans in the roasting barrel 5;

[0044] S2, during the roasting process, the driving mechanism 6 drives the spreading and stirring assembly 8 to rotate and stir and spread the green coffee beans in the roasting barrel 5 so that they are fully heated;

[0045] S3, after roasting is completed, the two hydraulic rods 1 2 are controlled to shorten and the two hydraulic rods 2 3 are controlled to extend, so that the opening side of the roasting barrel 5 is tilted downward, and then the stirring assembly 8 is spread and stirred to stir the green coffee beans, so that the green coffee beans will flow out from the opening of the roasting barrel 5 and fall on the lower hopper 9.

[0046] Filling: Green coffee beans are pneumatically conveyed to a collecting container 11 with a valve, where the green coffee is separated from the conveying air, and the air is released through an exhaust pipe 12. The gate of the collecting container 11 is located at the lower end of the collecting container 11. After receiving a signal from a programmable controller, the gate of the collecting container 11 opens, and the green coffee beans enter the filling container 13. Below the filling container 13 is a filling valve 14. When the filling temperature in the roasting drum reaches a certain level, the filling valve 14 is pneumatically driven downward, and the green coffee beans flow from the filling container into the roasting equipment under the action of gravity.

[0047] Roasting: The roasting equipment intensively circulates and mixes the green coffee beans to transfer the heat evenly. The heater 10 releases heat to heat and roast the green coffee beans in the roasting equipment. The temperature is automatically increased to a preset rated value by setting the controller and then kept constant. The exhaust gas generated during the roasting process is sucked away by the roasting fan 16 and transported to the roasting cyclone separator 15. Through this link, the silver skin and dust are separated from the roasting air by centrifugal force. As the roasting progresses, the heat supply of the roasting equipment is gradually reduced by lowering the temperature of the heater 10. The roasting process ends at a pre-programmed time or temperature point, or after the measured color grade is reached.

[0048] In this embodiment, when in use, after the green coffee beans are put into the roasting barrel 5 through the feeding hopper 7, the motor 1 61 is started to drive the pulley 1 62 to rotate, the pulley 1 62 then drives the pulley 2 65 to rotate through the synchronous belt, the pulley 2 65 then drives the frame 63 to rotate through the transmission shaft 64, and the frame 63 then drives the entire paving and stirring assembly 8 to rotate through one of the circular plates 81;

[0049] For example Figure 3 and Figure 4 As shown, when the paving and stirring assembly 8 rotates clockwise, the scraper 89 will scoop up the green coffee beans in the roasting barrel 5. When the scraper 89 rotates from a horizontal state to an upward tilt, the scooped green coffee beans will enter the second channel 87 corresponding to the scraper 89. Then, when the scraper 89 gradually rotates to an upward vertical state, the green coffee beans will fall through the scraper 89 into the connected channel three 814, and then fall between the multiple fan-shaped plates 82 and flow out from the opposite channel one 84.

[0050] In the above process, the rotating scraper 89 can scoop up the green coffee beans accumulated at the bottom of the roasting barrel 5, so that they are evenly mixed and fully heated. In the process of the green coffee beans passing through the channel 1 84 and the channel 2 87, since the green coffee beans are a thin layer, they will not be accumulated thickly, thereby ensuring that each green coffee bean can be heated evenly.

[0051] When the green coffee beans are stirred and roasted by the evenly spread stirring assembly 8 in the roasting barrel 5, the two hydraulic rods 1-2 are controlled to shorten and the two hydraulic rods 2-3 are controlled to extend, so that the side of the roasting barrel 5 near the opening is tilted downward. Then, when the evenly spread stirring assembly 8 rotates, the green coffee beans in the roasting barrel 5 will continuously flow out from the multiple through holes 801 on the circular plate 81 near the opening of the roasting barrel 5, and finally flow out from the opening of the roasting barrel 5 and fall on the lower hopper 9. During the roasting process, in order to prevent the green coffee beans from flowing out from the opening of the roasting barrel 5, the lengths of the two hydraulic rods 2-3 and the two hydraulic rods 1-2 should be adjusted so that the opening of the roasting barrel 5 is slightly facing upward.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
