In addition, 30 shown in FIG. 1 has a plurality of mounting members 31 on which the inlet 32a is positioned in the main body 10, the outlet 32b is connected to the suction passage S, and the fish knot raw material 1 to be dried is placed inside. As shown in FIG. 4, a plurality of mounting members 31 are provided in the suction passage S, and for example, a plurality of mounting members 31 are provided in the horizontal direction and the vertical direction, respectively.
Reference numeral 32 denotes a second door that can freely open and close the opening 30 </ b> A of the mounting body 30, and the second door 32 is provided with a plurality of air inlets 32 a. For example, when a plurality of horizontal members 32C that cross the frame body 32W are provided in the frame body 32W, the plurality of air inlets 32a are formed by the adjacent horizontal members 32C and 32C among the plurality of horizontal members 32C and 32C. (See FIGS. 2 and 5).
