At the same time, moving the jet back and forth can also make the biofuel heat more uniform and the drying effect is better.

[0026] Reference Figure 2 and Figure 3 The reciprocating assembly 14 includes a rotating shaft 1406, which is rotatably connected to the inner top of the drying box 1, one end of the rotating shaft 1406 is fixedly connected to a turntable 1401, the outside of the turntable 1401 is fixedly connected to a fixed block 1403, the outside of the fixed block 1403 is slidably connected to a limit block 1402, the outside of the limit block 1402 is fixedly connected to two sliding rods 1404, the outsides of the two sliding rods 1404 are fixedly connected to two injection pipes 1407, the inside of the drying box 1 is fixedly connected to two fixed rods 1405; the outer side of the sliding rod 1404 is slidably connected to the inside of the fixed rod 1405.

[0027] Specifically, the rotation of the rotating shaft 1406 drives the turntable 1401 to rotate, thereby causing the fixed block 1403 to move in the internal groove of the limit block 1402, so that the two sliding rods 1404 connected to the outside of the limit block 1402 repeatedly move left and right, thereby driving the jet pipe 1407 to move and spray heated gas to dry the biofuel in the drum 4.
