PROBLEM TO BE SOLVED: To provide a multi-layer food producing device constituted by a simple structure capable of utilizing sticky food ingredients as outer layer food ingredients and inner layer food ingredients for producing high quality multi-layer food. SOLUTION: a multi-layer food producing device 10 including: an inner layer food ingredient pressing and conveying device 22 and an outer layer food ingredient pressing and conveying device 32 constituted by a uniaxial eccentric spiral pump； and an ejecting part 40. An ejecting nozzle 42mounted on the ejecting part 40 is a dual structure inserted from inside of an outer layer food ingredient ejecting tube 58, that is connected to the outer layer food ingredient pressing and conveying device 32, into an inner layer food ingredient ejecting tube 56 connected to the inner layer food ingredient pressing and conveying device 22.本發明的課題為其目的為提供一種可使用具有黏性的食材當作外層食材及內層食材製造品質高的多層食材，進而裝置構成簡單的多層食品製造裝置。本發明解決手段為一種多層食品製造裝置10，包含:藉由單軸偏心螺旋泵構成之內層食材壓送裝置22與外層食材壓送裝置32；吐出部40。配設於吐出部40的吐出噴嘴42為在連接於外層食材壓送裝置32的外層食材吐出筒58的內側插入連接於內層食材壓送裝置22的內層食材吐出筒56之雙重構造。
