PROBLEM TO BE SOLVED: To provide a pregelatinized grain flour manufacturing device capable of forcibly sucking and recovering pregelatinized grain flour together with air near a discharge part from the discharge part, capable of lowering moisture content in air near the discharge part by sucking and recovering the pregelatinized grain flour and air near the discharge part and preventing dew condensation on an inner surface of the discharge part from occurring, and capable of continuously manufacturing the pregelatinized grain flour.SOLUTION: A pregelatinized grain flour manufacturing device includes a grinding part 1 capable of shearing and crushing grain flour E, a supply part 4 capable of supplying grain flour to the grinding part and a discharge part 6 capable of discharging the grain flour sheared and crushed by the grinding part from the grinding part, further includes a heating part 9 for heating a grinding board 3 and, in collaboration of heating of grain flour by means of the heating part with shear crushing of grain flour, manufactures the pregelatinized grain flour F. Therein, a suction recovering part 10 for sucking and recovering the pregelatinized grain flour discharged from the discharge part is provided.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】吸引回収部によりアルファ化穀粉及び排出部近傍の空気を排出部から強制的に一緒に吸引回収することができ、アルファ化穀粉及び排出部近傍の空気を排出部から強制的に一緒に吸引回収することにより排出部近傍の空気中の水分量を低下させて排出部内面の結露の発生を防ぐことができ、アルファ化穀粉を連続して製造することができる。【解決手段】穀粒Eを剪断粉砕可能な擂潰部1、擂潰部に穀粒を供給可能な供給部4及び擂潰部により剪断粉砕された穀粉を擂潰部から排出可能な排出部6を備え、擂潰盤3を加熱する加熱部9を設け、加熱部による穀粒の加熱及び穀粒の剪断粉砕の協動によりアルファ化穀粉Fを製造する装置において、上記排出部から排出されてくるアルファ化穀粉を吸引回収する吸引回収部10を設けてなる。【選択図】図1
