[0023] In specific implementation, according to Figures 1-4The coffee beans are put into the roasting cylinder 101 through the feeding hopper 102 to the inside of the stirring mesh cover one 206 and the stirring mesh cover two 208, and the hot air generated by the roasting cylinder 101 passes through the stirring mesh cover one 206 and the stirring mesh cover two 208 to heat the coffee beans. At this time, the driving motor 2 is started to simultaneously drive the small synchronous gear one 201 and the large synchronous gear one 210 to rotate. When the large synchronous gear one 210 rotates, the large synchronous gear one 210 and the large synchronous gear two 212 are in meshing butt joint with the synchronous belt two 211, so that the large synchronous gear one 210 can drive the two large synchronous gear two 212 to rotate through the synchronous belt two 211, thereby driving the toothed disc column one 213 and the toothed disc column two 2131 to butt joint through the large synchronous gear two 212. The toothed disc column one 213 and the toothed disc column two 2131 are in meshing butt joint with the tooth ring 209, respectively, so that the toothed disc column one 213 and the toothed disc column two 2131 drive the tooth ring 209 to rotate, respectively, and the rotation direction of the tooth ring 209 of the toothed disc column one 213 is opposite to that of the toothed disc column two 2131. The rotation direction of the two adjacent stirring mesh cover one 206 is opposite, and the stirring mesh cover one 206 can drive the stirring mesh cover two 208 to rotate through the connecting ring 207, so that the beans can be more uniformly stirred and turned during the roasting process, and the beans can be more uniformly contacted with the hot air. The opposite rotation direction can effectively break the aggregation and accumulation of the beans, and the different rotation directions can make the beans collide with each other to prevent the beans from forming lumps. When the small synchronous gear one 201 rotates, the small synchronous gear one 201 and the small synchronous gear two 203 are in meshing butt joint with the synchronous belt one 202, so that the small synchronous gear one 201 can drive the small synchronous gear two 203 to rotate through the synchronous belt one 202, thereby driving the push rod 204 to rotate in the containing groove 205. The convex rod of the push rod 204 gradually approaches the stirring mesh cover two 208, so that the convex rod of the push rod 204 collides with the stirring mesh cover two 208. The top end of the convex rod of the push rod 204 is adhered with a deformable rubber block, so that the push rod 204 is not easy to damage the stirring mesh cover two 208. The connecting ring 207 is made of a deformable rubber material, so that when the push rod 204 collides with the stirring mesh cover two 208, the connecting ring 207 deforms, thereby enabling the stirring mesh cover two 208 to vibrate, so that the stirring mesh cover two 208 further breaks the lumps of the beans, thereby enabling the coffee roaster to uniformly roast the beans, and the beans are not easy to form lumps, thereby preventing the beans from being locally over-roasted or burned.
[0024] In summary, the driving motor 2 is started, the rotating directions of the two adjacent stirring mesh covers 206 are opposite, the stirring mesh cover 206 can drive the stirring mesh cover 208 to rotate through the connecting ring 207, the beans are stirred and turned more uniformly during the roasting process, the beans can be contacted with the hot air more uniformly, the opposite rotating directions can effectively break the gathering and accumulation of the beans, the different rotating directions can make the beans collide with each other, prevent the beans from forming lumps, the push rod 204 collides with the stirring mesh cover 208, the stirring mesh cover 208 can vibrate, the stirring mesh cover 208 further breaks the lumps of the beans, the coffee roaster is convenient for uniformly roasting the beans, the beans are not easy to form lumps, and the beans are not easy to cause local over-roasting or burning, and the contents not described in detail in the description belong to the prior art known by the person skilled in the art.
