The invention relates to the field of dairy products, in particular to pretreatment deslagging equipment for dairy product packaging and a deslagging method of the pretreatment deslagging equipment. The cheese packaging box solves the technical problems that after cheese is pressed and formed, some protruding cheese disintegrating
slag can be reserved on the surface of the cheese, the packaging effect is affected, and the cheese is inconvenient to put into the packaging box due to the fact that the packaging box is prone to being concaved inwards. According to the technical scheme, the pretreatment deslagging equipment for dairy product packaging comprises a supporting frame, a disintegrating
slag collecting box and the like; and a disintegrating
slag collecting box is arranged on the left side in the supporting frame. According to the cheese residue collecting device, residues on the surface of cheese are removed, the cheese residues stored in the collecting frame are transferred in a linkage mode, manual taking-out is not needed, continuous cheese residue collecting is rapidly carried out, the working efficiency is improved, meanwhile, the inner wall of a packaging box is leveled, the corners of the packaging box are pressed through semi-cylindrical protrusions of two pressing plates, and the packaging box is convenient to use. And corner blind areas during pressing are avoided, subsequent cheese can be quickly put in conveniently, and the situation that the cheese is damaged is avoided.
