Beneficial Effects

[0016] The present invention provides a coloring device for roast chicken processing.

The second spring is arranged so that when the sealing plate moves upwards, the triangular limiting plate moves outwards. When one end of the inner side of the second supporting plate is flush with the slide groove, the piston loses its supporting force. The elastic force of the first spring pulls the piston downwards, so that the piston draws air into the square frame, thereby drawing the coloring liquid on the surface of the chicken skin back into the inner discharge pipe, so as to prevent the liquid on the surface of the roast chicken from dripping due to gravity, resulting in obvious coloring drip marks on the surface of the roast chicken after it is air-dried.

By starting the rotating motor, the rotating motor rotates forward, driving the first reciprocating screw rod to rotate forward, so that the first rotating rod rotates forward, and the second reciprocating screw rod rotates forward. Through the limiting of the limit frame and the limit rod, the lifting plate, the limit rod and the connecting plate drive the electric rotating hook to do up and down reciprocating motion. The roast chicken is rotated by the set electric rotating hook, and the coloring liquid overflows from the inner discharge pipe and the outer movable pipe through the gap between the ball and the bearing ring. The coloring liquid is distributed on the surface of the ball, so that the skin of the roast chicken can be colored without dead angles, and the skin of the roast chicken is more evenly colored, which greatly reduces the waste of coloring liquid. By starting the electric telescopic rod, The triangular sliding frame descends to the specified position, at which time the sealing plate is reset, so that the second support plate is located on one side of the bottom of the piston but does not contact the piston. The electric telescopic rod is started to rise, and the triangular sliding frame and the triangular limiting plate are engaged with each other, so that the triangular sliding frame pushes the triangular limiting plate to move to one side, thereby extending the second support plate and supporting the piston again. At this time, the electric telescopic rod stops working, and the cycle is repeated, so that the coloring liquid remaining on the surface of the chicken skin is continuously recycled and utilized. The liquid stays in the outside world for a short time, effectively avoiding the food safety risks caused by multiple recycling of the coloring liquid. BRIEF DESCRIPTION OF THE DRAWINGS
