The object of the present invention is to provide a continuous curding machine for tofu products, designed to be capable of manufacturing clean tofu products in that it will not cause a leakage of soymilk and seams and/or wrinkles on the tofu, sanitary and simple in mechanism, easy to perform transport of tofu to following processes, and capable of forming a deep coagulation compartment so as to enable “tatedori” (taking the depth of the coagulation compartment to be the longest side of the tofu). The machine is equipped with the conveyor belt C that transports coagulating coagulant-added soymilk as well as with a concave member 10 disposed underneath the belt. The belt C is conveyed as it is shaped into concave in accordance with the form of the said concave member 10 disposed underneath, and forms a coagulating compartment 10a, 10b.
