DIE FOR MANUFACTURING FOAMED FOOD

PROBLEM TO BE SOLVED: To provide a die for manufacturing foamed food enabling to manufacture a foamed food with reduced water content and bulk density, and having an excellent palatability. SOLUTION: The die for manufacturing foamed food is used in manufacturing foamed food by extrusion molding and is provided with an extruding path 2 through which a raw material is extruded. The extruding path 2 has a contraction section 21 in which the cross section gradually reduces from an inlet port 2A of a material to an exit port 2B, and an expanding section 22 with a cross section expanding with a difference in level from the most contracted part 211 of the contraction section 21 and keeping the cross section for a constant length. The expanding section 22 is preferably formed with a material with a low coefficient of dynamic friction than that of the contraction section 21. COPYRIGHT: (C)2009,JPO&INPIT
