The hot air blowing portions are configured to apply hot air to the item to be dried in parallel with irradiation of the microwaves by the microwave irradiation portions.

Abstract: A method for manufacturing a honeycomb structure includes producing a pillar-shaped honeycomb molded body in which a plurality of cells are placed in parallel with one another in a longitudinal direction with a cell wall therebetween by molding a ceramic raw material; and producing a honeycomb fired body by carrying out a single or a plurality of treatments including at least a firing treatment on the honeycomb molded body. The method further includes temporarily storing the treated honeycomb molded body on which the single or plurality of treatments have been carried out in a molded body storage container; taking out the treated honeycomb molded body placed in the molded body storage container from the molded body storage container; and conveying the taken-out honeycomb molded body to a subsequent process.

Abstract: A degreasing jig assembling apparatus includes a robot arm and a table or a conveyor on which a degreasing jig including a bottom plate and a cover member is placed. A ceramic molded body is mounted on the degreasing jig upon degreasing the ceramic molded body. The ceramic molded body is mounted on the degreasing jig on the table or the conveyor. The degreasing jig assembling apparatus further includes a molding body mounting mechanism and a cover member. The molding body mounting mechanism mounts the ceramic molded body at a predetermined position on the bottom plate placed on the table or the conveyor by using the robot arm. The cover member attaching mechanism attaches the cover member to the bottom plate in a manner so as to cover the ceramic molded body mounted on the bottom plate.
