Dependent claims

A drying device for a square pillar-shaped honeycomb molded body, comprising a plurality of drying jigs and a piling member,

wherein each of the plurality of drying jigs comprises:
an upper jig and a lower jig, wherein the upper jig and the lower jig are adapted to form an enclosure, the enclosure being adapted to substantially surround the honeycomb molded body and substantially cover a side face of the honeycomb molded body and being configured so that the longitudinal direction of said honeycomb molded body is held in the horizontal direction while opposite angles of a square shape in the cross-section perpendicular to the longitudinal direction of said honeycomb molded body are located on a same vertical line;
and
a fixing member for affixing the upper jig and the lower jig together to form the enclosure;
and
wherein the piling member is adapted to support one drying jig while being supported by another drying jig when more than one drying jigs are stacked, and the piling member comprises:
a first V-shaped notch for engaging the lower jig of the drying jig, and
a second V-shaped notch for engaging the upper jig of the drying jig, wherein a first vertex portion of the first V-shaped notch and a second vertex portion of the second V-shaped notch are substantially aligned along the vertical line.

molding a ceramic material into a square pillar-shaped honeycomb molded;
drying said honeycomb molded body using a drying device comprising a drying jig and a piling member, wherein the drying jig comprises an upper jig, a lower jig, and a fixing member;
and
firing said honeycomb molded body;
wherein the drying of said honeycomb molded body further comprises:
affixing the upper jig and the lower jig together using at least one fixing member to form an enclosure in the drying jig, the enclosure being adapted to substantially surround the honeycomb molded body and cover a side face of the honeycomb molded body and being configured so that the longitudinal direction of said honeycomb molded body is held in the horizontal direction while opposite angles of a square shape in the cross-section perpendicular to the longitudinal direction of said honeycomb molded body are located on a same vertical line;
and
placing the honeycomb molded body in the enclosure of the drying jig;
stacking a plurality of drying jigs vertically using at least one piling member so that the piling member supports one drying jig while being supported by another drying jig, wherein the piling member comprises
a first V-shaped notch for engaging the lower jig of the drying jig, and
a second V-shaped notch for engaging the upper jig of the drying jig, wherein a first vertex portion of the first V-shaped notch and a second vertex portion of the second V-shaped notch are substantially aligned along the vertical line;
and
placing the plurality of vertically stacked drying jigs inside a dryer for a predetermined period of time.
