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

A solid-liquid separating apparatus for separating a slurry into a solid component and a liquid component, which apparatus comprises:

• 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;
• wherein while fibrous solid-liquid separating filters are placed 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, the pressing rod is driven into the mold cavity to compress the slurry within the mold unit, and a resultant solid component is ejected out of the mold unit together with the solid-liquid separating filters.
