The PLC controller 11 controls the output shaft of the fourth motor 10 to rotate, and the output shaft of the fourth motor 10 drives the first rotating shaft 303 to rotate, which drives the crushing blades 302 on the outer side of the first rotating shaft 303 to rotate, thereby achieving the crushing of the citrus peel in the crushing chamber 301. The crushed citrus peel falls to the lowest point through the inclined sliding surface 304 and then enters the first section of the discharging pipeline 601 of the discharging assembly 6. The output shaft of the second motor 603 drives the spiral transmission blade 604 to rotate in the first section of the discharging pipeline 601, thereby achieving the spiral transmission of the citrus peel in the first section of the discharging pipeline 601 and guiding it out into the box body 901 through the second section of the discharging pipeline 605.

[0053] After distillation for a certain time, the third motor 907 of the storage box structure 9 drives the second supporting rod 906 to rotate the box body 901 by ninety degrees, so that the third rotating shaft 903 is rotated from the axial vertical state to the axial horizontal state, then the push rod of the second electric telescopic rod 908 is extended to drive the box body 901 to pass through the inlet and outlet opening slot 407 and enter the waste residue collection box 2, at this time, the third motor 907 drives the second supporting rod 906 to continue to rotate the box body 901 by ninety degrees, so that the third rotating shaft 903 is rotated from the axial horizontal state to the vertical state, and at this time, the opening of the box body 901 is downward, the residue discharging and cleaning assembly 4 realizes cleaning of the box body 901, the water liquid passes through the liquid passage 902 to wash the citrus peels in the box body 901 downward and fall to the bottom surface in the waste residue collection box 2, and the box body 901 is reset under the driving of the third motor 907 and the second electric telescopic rod 908;
