Solid-liquid separating method, solid-liquid separator and solidified product

A solid-liquid separating method for separating a slurry into a solid component and a liquid component, which is accomplished by utilization of a solid-liquid separating apparatus comprising a mold unit having a cylindrical mold cavity defined therein for accommodating the slurry and also having first and second open ends opposite to each other, a gate for selectively opening and closing the second open end of the mold unit and a pressing rod slidable into the cavity of the mold unit to urge the slurry against the gate, then held in position to close the second open end of the mold unit, to thereby compress the slurry, which method comprises:

• placing fibrous solid-liquid separating filters, each of which is a round sheet, in the mold unit so as to seal a gap, delimited between an inner peripheral surface of the mold unit and an outer periphery of a leading end of the pressing rod, and another gap delimited between respective contact surfaces of the gate and the mold unit, respectively;
• driving the pressing rod into the mold cavity to compress the slurry within the mold unit;
• and
• ejecting a resultant solid component, in a form of a cylindrical solidified block body with opposite ends thereof having respective fibrous solid-liquid separating filters, having respective protruding portions protruding axially along the inner peripheral surface of the mold unit so as to form a cylindrical surface, stuck thereon, out of the mold unit.
