The invention belongs to the field of food processing equipment, and particularly relates to an efficient aquatic product seafood processing device. The device comprises a hanging assembly, a conveying assembly, a salt smearing assembly, a cleaning assembly, a stacking assembly, a pressing assembly and a base, a fish body A which is cut into two pieces which are connected is fixed in the hanging assembly, the hanging assembly is arranged on the conveying assembly, the conveying assembly drives the hanging assembly to sequentially pass through the salt smearing assembly and the cleaning assembly, then the fish body A is taken down from the hanging assembly, the fish body A is horizontally placed in the stacking assembly, the fish body in the stacking assembly is pressed by the pressing assembly, and the conveying assembly, the salt smearing assembly, the cleaning assembly, the stacking assembly and the pressing assembly are all arranged on the base. The device has the advantages that the structure is reasonable, all working procedures are in cooperation, the hanging assembly can quickly hang and process the fish body, the operation of salt smearing on the fish body adopts an automatic salt smearing mode, and uneven smearing and manpower waste caused by manual salt smearing are avoided, so that the salt smearing efficiency is improved.
