The remaining non-peeled fruit continues to move along with the stem to the second drum 100 along with the movable scraping teeth 200, and the previous work is repeated to perform the second peeling. The detached fruit drops from the pores of the second outer barrier 300 to the third cleaning roller 900. Finally, the stalk follower scraping teeth 200 are thrown from the second drum 100 onto the second cleaning roll 800. The detached fruit is conveyed to the next stage, and the stalks are conveyed from the second cleaning roll 800 to another process. And the cleaning system finishes the work. If the number of the rollers 100 is increased, the above implementation process is repeatedly increased in sequence. When the working stem crops are changed, the number of the fixed scraping teeth 400 and the movable scraping teeth 200 can be reduced or increased, or the distance between the fixed scraping teeth 400 and the movable scraping teeth 200 can be adjusted, and the impact force can be adjusted by changing the rotating speed of the roller 100, so that the stem and fruit separating operation of different stem crops can be adapted.
