The present invention relates to a stock re-pulper designed to macerate stock put into a stock tub. The stock re-pulper comprises first and second porous plate disposed in the stock tub and respectively having first and second holes, first macerating blades disposed to confront one surface of the first porous plate and made to be rotated in proximity to a first open area of the first porous plate, second macerating blades disposed to confront one surface of the second porous plate in proximity to a second open area and made to be rotated concentrically with respect to the center of rotation of the first macerating blades, and a pump blade disposed to confront the other surface of the first porous plate in proximity to the first open area and made to be rotated concentrically with respect to the center of rotation of the first macerating blades. With this construction, when a drive source is put into operation, the stock is positively guided between the first macerating blades and the first porous plate and positively guided between the first porous plate and the pump blade and further guided between the second macerating blades and the second porous plate, which can provide a high maceration efficiency while suppressing the power needed for the maceration processing.
