[Problem] To provide: an apparatus which is for use in manufacturing a nano-pulverized product and which can yield a nano-pulverized product with high productivity while minimizing the fibrillation-associated lowering in the degree of polymerization; and a process for manufacturing a nano -pulverized product. [Solution] A polysaccharide slurry is circulated in a polysaccharide slurry supply line (3) through a chamber (2). In particular, a polysaccharide slurry in a tank (7) is circulated using a pump (8) in a circuit (9) formed by a vinyl hose, a rubber hose or the like. On the other hand, a non-polysaccharide slurry is circulated in a second liquid medium supply line (4) through the chamber (2). In particular, a non-polysaccharide slurry in a tank (10) is circulated using a pump (11) in a circuit through a heat exchanger (12) and a plunger (13). Thus, the non-polysaccharide slurry, which is circulated in the second liquid medium supply line (4), is jetted through an orifice against the polysaccharide slurry, which is circulated in the polysaccharide slurry supply line (3) and passes through the chamber (2). |
