This invention relates to the field of frozen seafood processing technology and discloses an automatic ice-coating device for shrimp tails, including an ice water tank, a conveyor belt, a material basket, a pressing plate, and an electric slide rail. The conveyor belt slowly transports the material basket along the ice water tank to complete the ice coating of frozen products.
