Abstract: A material passage whose height decreases progressively towards the downstream side is formed and a hopper (1), a pulverizer (3), a centrifugal separator (4) and a soybean milk receiver (12) are disposed in that order in the downstream direction along the passage. Accordingly, tofu (soybean curd) can be made more readily and automatically. (2) Juice of pulverization prepared by crushing water-containing soybeans with a pulverizer (3) is put into a centrifugal separator (4) consisting of a cylindrical rotary basket (43) rotating on its axis so as to separate soybean milk and bean-curd refuse. To make the apparatus compact, the pulverizer (3) and the centrifugal separator (4) are disposed in a casing having the same space.
