The invention discloses an automatic stiff aphid processing system which comprises an automatic stripping assembly and a split charging assembly. The automatic stripping assembly comprises a first conveying device, the first conveying device comprises a first conveying belt, and a tobacco leaf feeding position, a washing-brushing module, a collecting module and a tobacco leaf discharging positionare sequentially arranged on the first conveying belt; the split charging assembly comprises a second conveying device, the second conveying device comprises a second conveying belt, and an upper boxposition, a stiff aphid split charging module and a lower box position are sequentially arranged on the second conveying belt; the collecting module comprises a discharging port, and the direction ofthe discharging port faces the stiff aphid split charging module of the split charging assembly. By means of automatic operation of a production line, labor can be saved, stiff aphids can be efficiently and economically stripped from tobacco leaves, and then drying, impurity removal and collection are performed; stiff aphids which are not stripped from leaves are small in number and low in damagerate; in addition, the stiff aphids adjustable in number can be efficiently split-charged.
