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.

Abstract: A generally cylindrical thermally insulated ceramic container of imposing appearance suitable for use on dining tables comprises a double-wall ceramic container and insulation formed of a foaming resin of low thermal conductivity and contained in the inner cavity interposed between the two walls. The thermally insulated ceramic container is produced by preparing an inner green container wall and an outer green container wall one size larger, both of potter's dough, joining the two green container walls along the upper edges thereof with the walls radially opposed to each other across an intervening space (inner cavity), firing the resultant molded green double-wall container thereby producing a double-wall ceramic container, injecting an unfoamed or semi-foamed foaming resin into the inner cavity through a perforation bored in advance in the outer wall, and foaming the resin within the inner cavity.
