[0037] like Figure 1-9As shown, the present application provides a coffee fruit drying and throwing machine, including a frame 1, a driving device 2, a drying device 3 and a conveying device 4, a roller 124 is arranged at the bottom of the frame 1, a horizontal outer cylinder 11 is arranged on the frame 1, a feeding port 111 is formed at the first end of the outer cylinder 11, the driving device 2 includes a driving motor 26 assembly and a driving shaft group driven by the driving motor 26 assembly, the driving motor 26 assembly is arranged at the second end of the outer cylinder 11, the driving shaft group extends into the outer cylinder 11, the driving shaft group includes an outer shaft 21 that is coaxially arranged and has different rotation speeds and an inner shaft 22 that passes through the outer shaft 21, the rotation speed of the outer shaft 21 is higher than the rotation speed of the inner shaft 22, the drying device 3 includes a net cylinder 31 that is rotatably arranged in the outer cylinder 11, and the net cylinder 31 is fixedly connected to the inner shaft 22 The conveying device 4 includes a spiral blade 41 and a throwing assembly. The spiral blade 41 is rotatably arranged in the mesh cylinder 31. The spiral blade 41 is fixedly connected to the outer shaft 21 to realize rotation and form a spiral conveying channel for drying wet coffee fruits in the mesh cylinder 31. One end of the spiral conveying channel is connected to the feeding port 111, and the other end is connected to the throwing assembly. The throwing assembly includes a throwing cylinder 42 whose inner cavity is connected to the spiral conveying channel and an impeller 43 rotatably arranged in the inner cavity of the throwing cylinder 42. A throwing pipe 44 connected to the inner cavity is formed on the peripheral wall of the throwing cylinder 42. The impeller 43 is fixedly connected to the outer shaft 21 to realize rotation and form an airflow in the throwing cylinder 42 to throw the dried coffee fruits after drying. The dried coffee fruits are sent out from the throwing pipe 44 along with the airflow.

[0038] In the coffee fruit drying and throwing machine of the present application, wet coffee fruits are input from the feeding port 111 of the outer cylinder 11, and then the wet coffee fruits enter the net cylinder 31 of the drying device 3. The net cylinder 31 rotates under the drive of the inner shaft 22. The wet coffee fruits adhere to the inner wall of the net cylinder 31 under the action of centrifugal force, and the moisture on the wet coffee fruits is thrown out of the net cylinder 31 from the mesh holes of the net cylinder 31. At the same time, the spiral blades 41 in the net cylinder 31 rotate under the drive of the outer shaft 21. Since the rotation speed of the outer shaft 21 is higher than that of the inner shaft 22, the coffee fruit is sucked out of the net cylinder 31. The rotation speed of the spiral blade 41 is higher than that of the mesh drum 31, so the wet coffee fruits can still be pushed by the spiral blade 41. After being pushed, the dry coffee fruits enter the throwing drum 42. The impeller 43 in the inner cavity of the throwing drum 42 rotates under the drive of the outer shaft 21 to generate airflow. The dry coffee fruits are sent out from the throwing pipe 44 of the throwing drum 42 along with the airflow, thus completing the coffee fruit drying and throwing machine, thereby solving the technical problem of the lack of a horizontal dehydration mechanism separately provided for coffee fruits.

[0039] In order to conveniently discharge the water flowing out of the net cylinder 31 , the spin-drying device 3 further includes a water outlet trough 32 arranged below the net cylinder 31 , and a drainage pipe 33 is arranged at the bottom of the water outlet trough 32 .

[0040] Preferably, a buffer chamber is arranged between the feeding port 111 and the mesh cylinder 31 so that the wet coffee cherries input from the feeding port 111 can be buffered in the buffer chamber, making the whole process smoother. In order to set the buffer chamber, specifically, one end of the inner shaft 22 extends all the way into the end of the mesh cylinder 31 close to the feeding port 111, the first end of the mesh cylinder 31 is fixedly connected with the tapered sleeve 12, the outer ring of the wide end of the tapered sleeve 12 is fixedly connected to the mesh cylinder 31 through a flange edge, the inner ring of the wide end of the tapered sleeve 12 is provided with a connecting ring 121, a connecting hole is opened at the axis center of the connecting ring 121, a tightening sleeve 122 is arranged in the connecting hole, the connecting ring 121 is fixedly sleeved on one end of the inner shaft 22 through the tightening sleeve 122, one side of the connecting ring 121 is fixedly connected to the inner wall of the tapered sleeve 12 through a plurality of sheets 123, the internal space of the tapered sleeve 12 forms a buffer chamber, the buffer chamber is formed between the feeding port 111 and the spiral conveying channel, a gap is left between the outer periphery of the connecting ring 121 and the inner wall of the tapered sleeve 12 for wet coffee fruits to pass through, and accordingly, the shape of the first end of the outer cylinder 11 is adapted to the tapered sleeve 12 to accommodate the tapered sleeve 12.

[0041] Furthermore, in order to allow the wet coffee cherries flowing from the buffer chamber to better enter the inner wall of the mesh cylinder 31, the spiral blade 41 is provided with a dividing sheet 411 at the inlet end of the spiral conveying channel.

[0042] In order to better assemble the outer shaft 21 and the inner shaft 22 on the frame 1, a plurality of axial positioning grooves are arranged between the outer wall of the inner shaft 22 of the drive shaft group and the inner wall of the outer shaft 21, and each axial positioning groove is provided with an inner bearing 23 with guiding function on both the inner and outer walls to support and position the outer shaft 21.

Some of the subsequent process equipment is on the same floor as the coffee berry spin-drying and throwing machine, some are on different floors, and most are on the upper floor. Therefore, the throwing cylinder 42 needs to be configured to be rotatable, so as to adjust the position of the discharge port of the throwing tube 44, so that the discharge port of the throwing tube 44 can be on the same floor or on different floors. Specifically, the throwing cylinder 42 includes a cylinder body, and a cover plate 421 is configured at the first end of the cylinder body close to the driving device 2.
