The present invention discloses a processing, drying and disinfecting system of aquatic products. A structure of the processing, drying and disinfecting system of aquatic products comprises a dryer structure, a falling curtain, a first conveyor belt, a first fixing plate, a first roller connecting seat, screws, foot stands, an observation window, a switch button, an operation panel, adjustment buttons, a second fixing plate, a second roller connecting seat, an inclined slide plate and a second conveyor belt. A bottom part of the falling curtain is matched with a top part of the first conveyorbelt, a roller is arranged inside the first conveyor belt, a rear end of the first roller connecting seat is fixedly connected with a front end of the first fixing plate, and rear ends of the screws are vertically connected with a front end of the first roller connection seat. The processing, drying and disinfecting system of the aquatic products is provided with the dryer structure in structure,can adjust the dryer, accelerates a speed of a drying rod, can be flexibly adjusted according to the different aquatic products, and is extremely practical. Besides, a fan and a disinfection lamp arecombined, so that the processing, drying and disinfecting system can achieve the drying and disinfecting of the aquatic products in one step, shortens working time, reduces working steps and thus improves work efficiencies.
