The utility model provides a high-efficiency secondary re-freezing device, which relates to the technical field of re-freezing devices and comprises a
machine body, a motor I is fixed on the surface of the
machine body, a rotating rod I is mounted at the output end of the motor I, a rotating rod II is sleeved in the
machine body, and conveying belts are sleeved on the outer surfaces of the rotating rod I and the rotating rod II. According to the seafood
water cooling device, by arranging the machine body, the first motor, the first rotating rod, the second rotating rod, the conveying belt, the spiral single freezing machine, the operation panel, the fixing
barrel, the fixing block, the moving groove, the first
hydraulic cylinder and the like, in the
water cooling process of the device, seafood can be effectively conveyed to the lower end in sequence by arranging the rotating plate, the torsional spring, the fixing
barrel and the like; in the transportation process, the placing angle of seafood and the contact surface are changed for multiple times to spray
water flow, so that the possible dead angle which is not sprayed is effectively avoided, the seafood can be effectively prevented from going bad in the storage process, and meanwhile, the seafood freezing efficiency is improved.
