[0028] Working principle: When in use, when performing drying operation, before adding aquatic feed, first turn on the driving motor 13, the output shaft of the driving motor 13 drives the second gear 12 to rotate, the second gear 12 drives the first gear 11 meshed with it to rotate, the first gear 11 drives the rotating tube 9 to rotate, the rotating tube 9 drives the multiple connecting tubes 5 and the one-way valve 6 to rotate, and then the aquatic feed is added to the drying cylinder 3 through the feed hopper 7, and the multiple rotating connecting tubes 5 stir and crush the agglomerated aquatic feed;
